It was Nigel Short, in his game against Karpov in Dortmund 1 997, who re-introduced the daring pawn advance 5.e4! after 4.'ifc2 0-0 in the Classical Nimzo-Indian.

:.�·� '!J� . ;: ttS. � 'i!•'it . . ·�·· · ��· After Karpov's playable, but cau­ tious reply 5 ... d6, White kept some advantage and managed to win the game. The question 'how should Black really play here to maintain the balance?' was left unanswered. In the following years, however, the world's top players remained faith­ ful to the reliable 5.a3 and ignored this new and more energetic option for White. Occasionally White would use 5 .e4 to surprise his oppo­ nent - often with striking success ­ but the move remained unpopular among leading players. The pro­ verbial exception to the rule was the TV game Krarnnik-Adams, Co­ logne 1998, but in spite of his vic­ tory, Kramnik sounded pessimistic

about White's true chances in that variation. What the author of these lines thinks, will be explained in the comments to this recent game:

Ivanisevic,Ivan Gligoric,Svetozar Herceg Novi tt 2001 (6)

1 .d4 tt:lf6 2.c4 e6 3.tt:lc3 �b4 4.'®'c2 0-0 5.e4 d5 Being theoretically 'better devel­ oped' Black needs to open the po­ sition. Less efficient is 5 ... d6 (see the afore-mentioned game Short­ Karpov, or Kir. Georgiev-Epishin, Germany 1999), and risky is 5 . . . c5 6.e5 cd4 7.a3 dc3 8.ab4 tt:lg4 9.'ifc3 etc., as in Goldin-Z. Al­ masi, Yugoslavia 1998.

6.e5 tt:le4 7.�d3 White should hurry with his devel­ opment. Inferior is 7 .a3 �c3 8.bc3 c5 9.�d3 'iVa5 ! etc. (Kelecevic­ Abramovic, Yugoslavia 1 984).

7...c5 8.cd5 In case of the immediate 8.tt:le2 cd4 9.tt:ld4 Black has the move 9 ... dc4 ! .

8. . .ed5 9.tt:le2 cd4 White is better after the 'normal' 9 . . . tt:lc6 1 0.0-0 tt:ld4 (not 10 ...cd4 1 1 .tt:ld5 !) 11.tt:ld4 cd4 12.tt:le4 de4 1 3.�e4 '®'h4 14.'iVd3 �e6 1 5.a3 �a5 1 6.g3 'iVh5 1 7.�f4 (Goldin­ Gligoric, Yugoslavia 1 998).

1 O.tt:ld4 tt:ld7 1 1 .f4 '®'h4 The alternative 1 1 ... tt:ldc5 1 2.0-0 is less promising for Black.

The only way to meet the deadly threat of 1 8 ... lLld3.

I called the second of the three arti­ cles on the Polugaevsky Variation I made for New In Chess Yearbook 'Questions about 1 0.ef6' . It is quite normal for a trainer to ask his pupil questions but it is quite ex­ traordinary that ifl raise a question in an article, a former pupil starts answering it! I always knew that some of my suggestions and con­ clusions in this Polu-trilogy would be improved by White or even re­ futed. In such a sharp line that's al­ most inevitable. Peter knows better than anyone else that I am not easily satisfied. No matter what a pupil does, I think he or she can always do better. However, this time Peter really deserves my praise. In the first half of the year he faced the Polugaevsky in a blindfold game against Ivanchuk and won a hair-raising game, ana­ lysed in Yearbook 59. At the World Team Championship in Erevan Peter faced another line of the Polugaevsky, initiated by 12 ... J:::!.a7. He wrapped up the Ira­ nian talent Ghaem Maghami very nicely in 27 moves. I would even call it a brilliant game, although Peter may think that something is wrong with me and I might be ill. His opponent underestimated the strength of the g7 pawn. I compared Peter' s game with my original analyses of Saravanan­ Mitrakanth, as given on page 2627 in Yearbook 59. White's play evidently forced me to analyse it all over again and this is what I dis­ covered.

1 8... tLld3 1 9.'ifd3 ed3 20.il.b6 ab6 21 .ttld4!? White hopes that this active ma­ noeuvre, eyeing the weak b5 square, is an improvement over the afore-mentioned game Ivanisevic­ Gomez Esteban, which saw 2 1 .\tod2 il.c5 22.tLlc l .!:!.d8 23J�i e l .itf5 24.ttlb3 .ite7 25.l::le 3 J:!.ac8 26.J:i:ae 1 l:i:c4 27.t2lc 1 h5 with suf­ ficient counterplay in the end­ game.

1 3...�h6! This was first played in I vanisevic­ Gomez Esteban, Elgoibar 2000, and it looks like an improvement over the usual 1 3 ... 'ifh5, when it is more problematic for the queen to rejoin the battle. In the afore­ mentioned game Kramnik-Adams, Cologne 1998, after 1 3 ... 'tl:Yh5 14. .itg2 lLlb6 (if 14 ... lLJdc5 1 5.0-0 .2.c3 1 6.bc3 .ith3 1 7.f5 !) 1 5.0-0 �c3 1 6.bc3 il.h3 ( 1 6 ...il.g4 ! ? is less clear) 1 7.f5 il.g2?! (Kramnik recommended 1 7 .. .f6 1 8.e6 .l::!. ac8 as a good chance for Black of ob­ taining strong counterplay, but who knows?) 1 8.�g2 lL:Jc4 (even here Kramnik considers 1 8 .. .f6 19.g4 'tl:Ye8 20.e6 'tl:Yc8 to be Black's chance to fight back) 19.g4 'tl:Yh4 20.f6 ! White had a winning attack.

1 4.il.g2

21 .. .f6! Was this a surprise for White, this move found over the board?

22.e6 The opening of the position cannot suit White.

22 ....itc5 23.tLlcb5 .!;!.a4! White claimed that he had over­ looked this move in his calcula­ tions. He made his reply after a long think, having seen that 24 ... J:!.d4 25.lLJd4 �d4 26 . .!ld3 �b2 27 .f5 is quite playable for White.

24. .!ld1 il.d4 25.b3! J:i.a5 26.lLld4 .ite6! 27.b4!? z:!.d5 28.lLle6 z:!.e8 29.'>itd2 J:!.e6 30. .!:!.de1 30. .!:!.he 1 ? J:!:e2 ! would lead to a lost pawn endgame for White !

30...�f7

1 4... 'ii!Ya6!

Draw agreed. Black made the offer because of his - premature impression that reaching a draw is quite easy for White.

by Tibor Karolyi VB 59

Leko,Peter Ghaem Maghami,Ehsan Erevan Wch-tt 2001 {7)

1 .e4 The only first move Peter plays. It may turn out one too few. Kaspa9

rov's last matches have shown that it can be a big disadvantage to have only one opening move at a world championship match. Anand had such a disaster against the Dragon against Kasparov in 1 995. Right after that match Anand started to play 1 .d4 as well. Kasparov did not prepare 1 .d4 against Kramnik and when the sting went out of 1 .e4, it cost him dearly. Of course Kram­ nik himself is an example of the contrary, as he was victorious with 1 .d4 only.

Taking the c2 pawn is best. In my analysis of the game Saravanan­ Mitrakanth, Indian Champion­ ship, Hyderabad 1 994, in Year­ book 59 I failed to point out the refutation of 1 8 . . .'Wia3? There are two !

1 ...c5 V2:lf3 d6 3.d4 cd4 4.tt:ld4 tt:lf6 5.tt:lc3 a6 6.�g5 This is the influence of Amador Rodriguez. He is a strong GM, but an even better trainer. When we both worked for Peter, I saw his good effect on Peter's chess. He contributed a lot to Peter raising his Elo from 2660 to 2745.

6 ... e6 7.f4 b5!?

Risky, of course, but it can be play­ able.

8.e5 deS 9.fe5 'Wic7 1 0.ef6 'Wie5 1 1 .�e2 'Wig5 1 2.0-0 l:ta7 Ivanchuk played 12 ... 'Wie5 against Leko at this year's Monaco Amber tournament. Peter won that game after a razor-sharp battle. It is not clear, however, whether White had an advantage in the opening and I would very much like to know what improvement Peter had pre­ pared against it.

'Wia4 20.tt:le5 This is Van der Vliet's suggestion from his 1978 monograph. It is very strong indeed. 20 ... �e4 (20 ... l::l.g 8 2 l .'Wib6 �e4 22.'iYb8 J:!.d8 23.'Wic7 and 20 ..

1 9.tt:lfg5! A 2660 player is already a terribly strong player for most of us, and we have problems imagining what a 2750 player does better. By the time Peter made this huge jump one thing among several I noticed was that he had visibly improved his handling of sharp Sicilians! 19.tt:lfg5 ! is an excellent move. It

opens the f-file and puts pressure on e6 and f7. Some commentators thought it was a novelty, but it was not. In my analysis in Yearbook 59 I only gave the immediate rook sac­ rifice 19 . .!:i:b4. This looks danger­ ous as well, but Black seems able to hold after 1 9 ... �b4 20.fg7. Not with 20 ... �c3? because of Van der Vliet's 1978 refutation 2 1 .tt:ld4 ! , e.g. 2 l . . . �d4 22.�d4 J:!.g8 23.ttlf6 'it>d8 24.'iYb6 '!J.c7 25.J:!.d1 (25.tt:lg8 'iYe2 26.�d6 also suf­ fices) 25...�d1 (25 . . .

20.J:!.b4 A pretty diversion, for sure ! In Yearbook 12 there is this game by Vladimir Dimitrov against Niko­ lay Vasilev, Pravets 1 988/89, in which he played 20.l:i:bdl . He also made some very nice analyses of it. However I think Black can get away with both 20 ... �e4 and 20 . . . g6. 20J:l:bdl ! ? swaps off the defending rook, but according to my analyses it is just a bit slow.

VB 58

During the Mirabal Active Chess Tournament held in Madrid earlier this year, my friend and co-author Diego Adla got the chance to play FIDE World Champion Viswana­ than Anand. As a prominent pro­ fessional player, Anand had just laid his hands on a copy of Year­ book 58 and had found our survey on the English Opening very inter­ esting. He quickly forgot who had written it, but he figured the tour­ nament in Madrid was a good oc­ casion to test the line and probably surprise his opponent. In fact, he was right insofar as Adla hadn't got a copy of Yearbook 58 yet! But obviously, my friend had 'some' knowledge of the line and man­ aged to draw.

Yearbook 60 featured a very inter­ esting game between I van Sokolov and Curt Hansen in a topical line of the Classical Nimzo-Indian. At home I started to analyse the game with my chess programs, trying to find an improvement for Black. After some hours I managed to do so with the new move 1 9 ... a6 ! This leads to some exciting complica­ tions but in my opinion Black is doing very much OK here. So far so good. As the opening ex­ pert for the chess programs Rebel Century and Chess Tiger I put the line in the opening books of both programs, not knowing if it would ever appear on the board. Luckily I didn't have to wait long. In the Open Dutch computer chess championship 2001 the line was played in the game COMP Diep versus COMP Rebel Century. In the end the white program man­ aged a draw, but I think this game is interesting for the theory of this line.

Referring to Van der Tak's survey on the drawing sacrifice 1 3 .�h6 in the Scotch Four Knights I would like to draw attention to an enter­ taining game played on May 26, 200 1 , during the Turkish Under 1 2 Schools Championship. I have added further information in the notes to this game. According to my analyses White retains a slight advantage after both 17 .f4 ttlg8 and 1 7 ... ttlg4.

Postscript by A. C. van der Tak: This game is indeed an interesting addition to the correspondence game Velcu-Kaunz given on page 133 in Yearbook 60. The verdict 'unclear' I attributed to 17 .f4 seems justified. In the introduction I commented that this move was 'probably aiming too high ' . In ret­ rospect this may be a bit too pessi­ mistic.

It was with vivid interest that I read the contribution by John van der Wiel on the Caro-Kann Defence: A Modern Defence Hybrid in Yearbook 59. This line also fea­ tures in my opening repertoire. I believe that the following two games of mine may be of some in­ terest to the theory of this line.

Almeida's Persistence

15

6.t2lc3 c5 7.e4 cd4 8.t2ld4 t2lc6 9. t2lc6 �c6, the strongest move for White was 10.�f4. White aims at controlling the h2-b8 diagonal in order to impede Black's manoeu­ vre �d8-b8, which was said to give Black excellent prospects af­ ter lO.�e2. This sequence was the subject of a survey by Kick Lange­ weg in Yearbook 39 and just re­ cently by Jan van de Mortel in Yearbook 59. Still IM (and soon to be IGM) Omar Almeida insists on playing 1 O.�e2, and when he used this line no fewer than three times over the summer in Cuba, it evoked my cu­ riosity. Let's see how these games continued after 1 0 . . .�b8 l l .f4 (al­ ternative moves have much poorer results).

The first game I present, Almeida­ Garcia Martinez, Santa Clara 200 1 , features ll hS, a seem­ ingly active attempt at counterplay by Black. It lends support to his knight on g4 anticipating an even­ tual quick e4-e5 break. Later on, however, the h pawn became a ma­ jor source of worry for Black, and White gradually built up pressure in the centre and on the left flank, only to decide matters after an er­ roneous black central break. In the second game, Almeida­ Delgado, Las Tunas 200 1 , Black just played ll d6. Much to my surprise this move, which I con­ sider as the most natural move in the position, has never been used before. In this encounter White continued in very aggressive style and got severely punished by the ...

quiet little move 17 . . . �b7 ! In my opinion White would do better castling kingside, which gives rise to a Sicilian-type of position. Four rounds later in the Cuban Championship Irisberto Herrera tried 10 ... �c7 and met l l .t2ld5 with the remarkable novelty 1 1 . . . � d8. Reluctantly White with­ drew his knight, when Black re­ frained from taking the draw and reverted to 1 2 ... �b8. After 1 3.f4 he chose the third way (13 e5) without ever reaching equality.

Update of an Old Sacrifice

by A. C. van der Tak Sl38.5

VB 57

It is impossible to keep updating each and every survey, of course, but we cannot withhold the follow­ ing recent game in the 1 1 .�b5 bishop sacrifice variation of the Sveshnikov. It updates the survey covering Dolmatov's queen 'sacrifice' 151 1 6 ...V//ic7 (who is sacrificing anyway? - Black gets three pieces for the queen) in his game against Baljon, Amsterdam 1979. Shirov's novelty 16.c3 ! ? seems to be a useful move, gaining a tempo compared to the previously played 1 6.tLlc7.

It has been predicted many times, by Capablanca and others: chess is about to peter out in a drawing game. When the computers ar­ rived on the chess scene the same message could be heard again. Fortunately, nothing is further from the truth. In all corners of the game sparkling novelties as well as new settings to old ideas are abounding. This includes the field of opening play. Look at this game from the jubilee l Oth edition of the Monarch As­ surance Isle of Man International.

When playing the Catalan Open­ ing, White, apart from the normal 3 . . . d5, also has to reckon with the reply 3 . . . c5, to which he can react either with 4.d5 (BI 2.3) or 4.4Jf3 (EO 45). A quarter of a century ago I spent a lot of time studying the position after

Black's last move has a certain logic to it. In the Benoni Black of­ ten goes to great length to realise this pawn thrust, so why not go for it on move 5 while the chance is there. The downside of the story is that Black tends to lag in develop­ ment and that the role of White's centre is increased. To the best of my knowledge Bot­ vinnik was the first grandmaster to play this line in a tournament game.

Here Timman went into a deep think. It is clear that White has beautiful compensation for the sacrificed pawn. Black's queen­ side is weakened and he always has to be aware of the line of march g l-f3-d4-c6 of the king's knight. By the time this position was on the board Petrosian had already drawn his game against Smyslov and he looked at our board with great interest. He smiled skepti­ cally and shook his head in his typical manner. Finally he switched off his hearing aid and said aloud to Smyslov: 'Black's position is on the verge of defeat! ' This evaluation of the former World Champion is obviously too categorical but it is more than apparent that Black has a difficult defensive task ahead of him.

started to analyse its conse­ quences and given that I liked what I saw I decided to employ it the next day.

Akopian, NikitilAfytos 1992, and Borriss-Tischbierek, Budapest 1996) prove that Black loses a tempo, and White gets a sweeping attack. The rook manoeuvre 15 ... l:!.d7 ! ? 16 . .ild3 l:!.e8 was introduced in modem tournament practice by the Hungarian grandmaster Jozsef Horvath, and Zoltan Ribli has also successfully applied it several times. Black provokes White to play 1 7.e5, after which 17 ... de5 1 8 . .ile5 'ifd8 ! gives Black good play ! See the games Alexieva­ J.Horvath, Cappelle la Grande

1 996, Volkmann-J .Horvath, Buda­ pest 1997 and Gaston-Lukov, Paris 2000. There was more meat for White in the positions without 17 .e5, but White could not get an advantage in these lines either. Black had no problems after 17. 'flh3 e5 ! in T.Horvath-De Sousa, Eger 1 997, Fogarasi-Ribli, Budapest 1998 and Gaston-Antal, Paris 2000. The moves 1 7.J:l:e3 ! ?, as in Vukovic­ P.Varga, Neum 2000, and 17.t/Jd1 ! ?, as in Bratovic-G .Pinter, Balatonlelle 200 1 , are interesting and more dangerous for Black. Finally, the move 16 . .ilf3 ! ?, tried in the game Lanka-Ribli, Austria 1 999, which restricts Black's manoeuvering space on the kingside, deserves further analysis.

Black's Task Black's task, on the other hand, is by no means trivial. He needs to move his centre pawns to develop but ... d5 (Baklan-Othman, Duis­ burg 1992; Hamdouchi-Canderas, Mancha 2000) , ...e5 (Anand-Chris­ tiansen, Monaco 1993; Bogdan­ Papp, Harkany 2000) and .. .f5/f6 (Zakharov-Sherbakov, St Peters­ burg 1999; Zhang Pengxiang­ Kang, Shenyang 1999) all have their downsides, as these games re­ veal. However, many strong black players have shown the promise in Black's position and David-Kram­ nik, France 1993, Bisguier-Gulko, 50

Los Angeles 1991 and Adams­ Krasenkow, Istanbul Olympiad 2000 are notable examples. It seems that Black's success depends on finding a role for his light­ squared bishop, and he sometimes has to be willing to sacrifice a pawn to do so (Uusi-Gulko, Soviet Union 1977; Bologan-Shabalov, Foxwoods 2000).

Which moves and when? 1 ) h4. I don't see how this helps White in general, and often serves merely to further weaken the light squares, but it is often played by strong players and Bezold-Volk-

STATISTICS

mann, Austrian Staatsliga 1999, is an example of its sting. 2) d4. It seems odd to undouble Black's pawns and wake up the bishops so d4 is rarely the most promising approach, but it can be quite effective, as shown in Mestel-Quinn, Eastbourne 1 973 and Timman-Visier Segovia, Las Palmas 1 977. 3) The tLlg5 manoeuvre. This is White's most dangerous idea at the moment (Bologan-Sveshnikov, Tallinn 2000; Hamdouchi-Mila­ dinovic, Saint Vincent 2000). It is particularly threatening when Black's knight is already commit-

ted to g6 (Psakhis-Nielsen, Gaus­ dal 1994 is a drastic example). However, when the knight is still on e7 Black has more options, and in the main game Rowson-Ansell, Scarborough 200 1 , B lack gives a vigorous demonstration of Black's prospects in this line. 4) Move order issues. If White begins with 5.b3 Black will often seek to blunt the diagonal at some point with .. .f6. In these cases White does well to exchange on f6 rather than allowing Black the pleasure of the spectacular ... tt:lh8 ! manoeuvre as in Bisguier-Gulko, Los Angeles 199 1 . However, in general b3 seems a little tame and there is a danger of the bishop banging its head against a black e5 pawn. 5.d3 suggests itself, but then Black should consider an early . . . e5 with 5 ... d6 or 5 .. .'f/c7 because the idea of c3 and d4 is less threatening. 5.0-0 is most flexible and probably best. Then if 5 ... tt:le7 6.d3 ! ? begs an important question, because 6 ... tt:lg6 7.tt:lg5 gives White some initiative, and yet there is no other consistent sixth move. This sug­ gests that Black might try some­ thing more flexible on move five like 5 .. .'f/c7 ! ? when ... tt:le7-g6 is still possible, but ... e5 and . . . tt:lf6 is a plausible alternative. Then 6.d3 e5 ! ? looks fine for Black and 6.b3, although perfectly playable, doesn't help prepare the funny business with tt:lg5.

Conclusion This line is highly complex. It is easier for White to play, but players like Shabalov, Gulko and Krasen­ kow often make it look like White is struggling to equalise. I suspect the biggest danger for both sides is that it's the sort of position where it's very easy to drift, and underesti­ mate the importance of each move. In any case, many black players steer clear of 3 ...e6 because 4..tc6 seems so annoying, but I hope this survey shows that this annoyance can be overcome, and that White also has things to worry about.

Sicilian Defence Alapin Variation 51 47.3

Who Was Wolfgang Heidenfeld? 1 .e4 c5 2.c3 tt:lf6 3.e5 tt:ld5 4.tt:lf3 tt:lc6 5.tt:la3 Biography Wolfgang Heidenfeld was born in Berlin, Germany, the 29th of May of 1 9 1 1 . He emigrated to South Africa in the mid- 1930's, although most likely he was forced to for be­ ing Jew. He had a variety ofjobs as crossword puzzle designer, writer, journalist and even door-to-door salesman. He was always against Apartheid. A good poker player, he was also an interesting chess player, eight times winner of the South African championship. In 1 956 he visited Dublin, he got

STATISTICS

married and moved there. Later on he spent a few years in Frankfurt. Curiously enough in 1959 he was both Irish and South African champion while domiciled in Ger­ many ! He settled back in Dublin in 1963 and became Irish Champion six times. In 1968 his son Mark was born, who is currently an in­ ternational master and was the 2000 Irish Champion, but he learned chess from his mother! According to an Internet page dedicated to him, his arrogance was characteristic. From this in­ tense, fascinating and a bit eccen­ tric biography, a free-thinker was given to chess, who created the

system which is analysed in this survey: 5.tt:la3.

Some ideas White's difficulties to get an ad­ vantage in the main line (5.d4 cd4 6 . .iilc4 tt:lb6) put the repertoire of many Alapin experts under fire. However, lost between the count­ less games stored in modem data­ bases, some with the astonishing 5.tt:la3 can be found. Nowadays, the variation is being gradually rescued, specially thanks to Vla­ dimir Baklan's efforts, who re­ vived the line with a couple of nice ideas accompanied with vic­ tories. Black is faced with unex­ pected problems, and this might be the main virtue of the Heiden­ feld System. Several set-ups seem to be playable and this makes the choice even more difficult. How­ ever, in each one of them, White should be able to complicate the game and reach a promising mid­ dle game.

Alternative defensive set-ups To oppose White's set-up there are several responses that can be sum­ marize in four categories. All they lead to an unbalanced piece distri­ bution, so some structure is indis­ pensable in order to understand the varied consequences that arise from each one of them. 77

A) The strange moves 5 .. .t2Jb6 and 5 ... a6 appear under this heading. The game Vysochin­ Sislian, Norderstedt 2000, shows all the power that Alapin­ supporters 'worship' : a queenside pawn majority, a strong knight on e5 and excellent piece coordina­ tion either for the middle game or the ending. Although things are not so easy if Black reverts to sounder resources, both moves lack a sophisticated touch. After all, why not attack White's center immediately? B) The modest 5 . . . e6, simply developing the kingside, suffered a setback in the game Baklan­ Anapolsky, Alushta 1 999, where the weakness created by the early b5 proved fatal in the resulting middle game. This excellent game culminated in an accurate and beautiful kingside attack. It re­ mains to be seen how White can improve on the game Vysochin­ Gritsak, Polanica Zdroj 200 1 , where the quick gain of the bishop pair did not assure any advantage, but without a doubt new discover­ ies can be expected in this line. C) The logical 5 ... d6, attacking White's center immediately, has been tested on several occasions. Our hero, the intrepid Heidenfeld, faced it several times. In his game against Penrose, Madrid 1 960, he tried to convert the classic small ad­ vantage of the queenside pawn ma­ jority under the well-known Alapinian adage: 'all or draw ' , but he was unsuccessful. Although very playable, this line doesn't seem attractive for Black. One of the main games, Dolzhikova­ Gaponenko, emphasizes this evaluation. D) Finally we arrive to what possibly will become the main an­ swer against White's system: 5 ...g6. The first main game Gla­ vina-Sion, where development was based on 6.g3, leaves a clear im­ pression: White has to be very ac­ curate, otherwise Black's central influence will be oppressive. This 78

was confirmed in the game Heidenfeld-Larsen, Havana Olym­ piad 1 966, and even more clearly in Bisguier-Fischer, Saltsjobaden Inter­ zonal 1962, where the great Bobby found the very precise 7 . ./ijc7 which leaves White with serious problems to defend the e5 pawn. The ball is now in White's court in this line. 6.'iVb3, played with assi­ duity by Baklan, seems an interest­ ing attempt. In any case, it demonstrates that there is a lot to discover. Baklan-Aagaard, Gronin­ gen 1 998, and Suer-Johannsson, Lugano Olympiad 1 968, are two good examples of the type of play that White seeks.

Conclusion Summarising, the line surveyed tries to open new possibilities in the almost exhausted and suffering Alapin. All this was brought to us by an illustrious player, who may get a deserved place in the vault of the variations 'with a name' .

Pirc Defence Byrne Variation PU 10.10

Problems in the Main Line 1 .e4 d6 2.d4 tt:lf6 3.4Jc3 g6 4.�g5 �g7 s:�Yd2 c6 6.f4 In his survey in Yearbook 48 Alex­ ander Beliavsky concludes that "the variation 4. �g5 is only at the beginning of its evolution." Since then, this active way of meeting the Pirc has only grown in popular­ ity. Beliavsky concentrated on the variations with h6, g5 followed by tt:lh5 to eliminate the white bishop, a principal way to deal with �g5. Here I will look at what is mostly considered as the main line: the possibilities arising after 5.'ii'd2 c6.

STATISTICS

After this move White has several options. With 6.�h6 he can enter a line that belongs to the 4.�e3complex. At present Black seems to be holding in this line. With 6.0-0-0 or 6.f3 White can choose for a set-up that is also similar to lines in the �e3-complex. The move I will be looking at is 6. f4 and this gives White's game its own character.

Black's options

After 6.f4 Black has different ways of playing against White's impres­ sive centre. Very logical is 6 ... b5, threatening pawn e4, and after

7 .�d3 following up with �g4 and 'ii'b6, putting pressure on d4. White's bishop on g5 is very ac­ tively placed but not doing much for the defense of d4. After 6 . . . b5 7.�d3 0-0 8.4Jf3 �g4 White has the choice: A) 9.0-0-0 leads to very sharp play. The game Tiviakov­ Delemarre gives a good idea of the dangers of White's attack. Recom­ mended to look at is also the game Peng Xiaomin-Gallagher where the black player in a very creative way launches a dangerous counter-attack. B) 9.e5 seems, after some ini­ tial successes, not to be very threatening. The game Wiersma­ Nijboer shows an interesting ap­ proach for Black. C) 9.f5, very direct, also seems not to be a big threat to Black. D) 9.0-0 is the most modest move but seems to pose the biggest problems to Black. After 9 ... 'ii'b 6 1 0.4:le2 tt:lbd7 l l .>t>hl ! Black doesn't seem to achieve equality with l l . . .d5. This variation will be analysed in the main games.

Looking for other ways

Although the set-up with jt_g4 and 'ii'b6 is recommended in several books on the Pirc Black has at this moment some problems getting a good game. So he is well advised 88

Survey PU 10. 10 to look for possible improvements. One idea is to continue with tt.:lb8d7-b6 after b5. The disadvantage of this is that it gives White a little bit a free hand to start his attacking plans, aiming at e5 or f5. A quick black disaster is seen in the game Minasian-Van Wely. Another idea is to play 6 ... 0-0 in­ stead of 6 ... b5. In answer to 7.�d3 Black can play 7 ... 1/lk'b6 and after 7.tt.:lf3 the direct 7 ... d5 is an extra possibility. Of course White has other moves like 7.0-0-0 or 7.e5. Other ways of deviating include an early b4 and an early �a5 and Mikhail Gurevich' experimental move tt.:lh5.

specialist in the �g5-variation). I did not manage to solve the open­ ing problems and had to give a pawn to keep playing. Very untypically, Tiviakov had difficul­ ties converting his big advantage and in time-pressure even went into a lost endgame. Two rounds later Jan Werle sur­ prised me by choosing the same variation. With 9 ... tt.:lbd7 I devi­ ated and after the strange-looking IO.tt.:le2 I almost immediately played IO . . . d5?, getting the same miserable position as against Tiviakov. This time I wasn't lucky: the young Dutch talent finished me off without difficulties.

Important ideas

The �g5-variation is a very inter­ esting line in which play can de­ velop in a lot of different ways. White has the choice of castling long or short. In the center he can choose between advancing with e5 (making the bishop on g5 work) or f5. Black has different ways of attack­ ing White's centre: e5, c5 or d5. Es­ pecially the last move, d5, is seen often in this line. After the logical e5 Black plays tt.:le4, attacking 'llk'd2 and �g5. After a subsequent tt.:lxe4 dxe4 the white knight on f3 lacks the g5 square to go to. That's why White often plays �xf6 first in re­ action to d5. After Black takes back with �xf6, e5 gives White some advantage. So Black may play exf6. Then it's often crucial if White is able to continue with f5 preventing a black f5 which lives up the bishop on g7.

Playing one-self

Every chess player has one game (ore maybe a few) he theoretically would play against himself. Play­ ing against myself probably the Pirc-�g5 would come on the board (unless I would chose to sur­ prise myself!). In this year's Open in Dieren I was, as Black, con­ fronted with my own plans. Not by myself but by Sergey Tiviakov (a

INTRODUCTION: Adrian Skelton STUDY MATERIAL: Skelton

French Defence Two Knights Variation FR 4.5

The Day of the Jackal 1 .e4 e6 V2:lc3 d5 3.ti:lf3 ti:lf6 4.e5 ti:lfd7 5.d4 c5 6.�g5 Adrian Skelton of Ireland recently put together a booklet called The Jackal Attack, which covers the French Two Knights Variation. Mr Skelton contacted the Yearbook editors with a view of having (part of) the material published in the Yearbook, and, as the subject (and the quality of the analysis) ap­ peared very interesting, we are happy to present to our readers 6 ...'li'b6, one of the most significant variations of the Jackal Attack.

Introduction

One of the main problems White encounters when playing against the French Defence is simply that he always faces an experienced opponent. For whereas White may encounter this particular opening, say, once in every dozen games or even more rarely, Black's experi­ ence of the opening is bound to be more extensive. Somewhere be­ tween a quarter and a third of Black's games are likely to feature the defence he specializes in. Whatever theoretical advantage White can claim by virtue of inher­ ent weaknesses in the French De­ fence must therefore realistically be set off against the fact that the game will largely follow an 94

agenda of Black's choosing. One way around this problem is to find a 'firewall' system which can be relied upon to muddle one's op­ ponent's theoretical 'book' . Such a system must of course be basically sound. At the same time it must not be innocuous. But if White can in­ deed find such an opening and use it regularly, then to some extent he has turned the tables on Black. This was my thinking during the '80s, when I began using the Two Knights Variation against the French (i.e. l .e4 e6 2.tt::lc3 d5 3.ti:lf3 ti:lf6 4.e5 ti:lfd7 5.d4 c5 6.dc5 tt::l c6 7.�f4) and because it was a sideline, I soon found that my specific knowledge of this sys­ tem, together with its infrequent use, definitely tilted the balance very much in my favour. Still, in spite of my favourable re­ sults something aroused my curi­ osity while at the same time puzzling me. You see, the opening moves quoted above, while not forced on Black, do represent the most likely variation that both players will pursue in the opening. What aroused my curiosity more and more as I continued to play 7 .�f4 game after game was simply: 'Why not 6.�g5 (?)' Thus far I had been in the habit of occasionally scribbling down my

own analysis of possible variations in the normal Two Knights French, a good way ofleaming how to han­ dle any opening. But now I began considering 6.�g5. So what is so good about 6.�g5 compared to 7.�f4 in the normal line? After all, at least 7 .�f4 helps control the e5 square, thematically as important in this branch of the French as in any other. The answer lies in the greater tactical possibili­ ties for White after 6.�g5. After Black's previous move he appears to have what looks for all the world like a very typical posi­ tion. Yet after 6.�g5 Black can easily find himself immersed in complex tactical evaluations he could well do without within only a few short moves. A quick flick through the relevant section should bear this out. Whereas the normal Two Knights French often muddles Black's 'book' preparation, the 6.�g5 line threatens to throw the book straight out the window and leave Black playing to White's agenda. ( ... )

Jackal with 6 ...'*'b6

In quite a few cases Black will re­ act to the 'hit' on his queen by moving it to b6. The temptation to 'kill two birds with one stone' is powerful - Black removes his

Survey FR 4.5 queen from danger and also counter-attacks an undefended pawn. However, the move 'iYb6, which enjoys a roguish but semi­ respectable reputation in many other opening systems, has al­ ready blotted its copybook in the normal Two Knights French (i.e with White playing �f4 instead of the Jackal's �g5). White's anti­ dote to 6 'iYb6 is 7.dc5!?, forcing Black into another potentially tricky choice. ...

Black is most likely to play one of the following: Line A: 7 ... �c5 Line B : 7 . . .'iYb2 Line C: 7 ... 'iYc5 Line D: 7.Ji:Jc5

Line A - 7 ... �c5 7...�c5 8.'iYd2!

It seems that White has overlooked something even more important than the double attack. Although few players are likely to 'jump in with both feet' and recklessly snatch the b-pawn at once, the pre­ paratory

Line C - 7...'ifc5

looks a more attractive proposi­ tion. However, things are not so simple, as we shall see. On 8 ... 'iYb4 White might try 9.0-0-0. For example 9 . . . 0-0 1 0.a3 'i!Ya5 1 L !lf6 ! and Black is in trou­ ble since l l ...gf6? appears to lose. Another possibility is 8 ...

This might well be Black's best try, since now there is little point in White placing a bishop or knight immediately on b5, both of which are answered with 8 . . . a6.

8.�d3

A natural square for the bishop. Other moves such as 8.a3 or 8.�e3 waste time. 95

8 ... tt:lc6

This is clearly best. Very risky is the premature 8 ... f6? ! , to which White might well reply with 9.tt:ld4 ! ?

9.0-0

It is probably best to give up the pawn. If 9.'iYe2 Black can try ei­ ther 9 ... d4 ! ? or 9... tt:ld4 both of which give him active play.

with fair prospects for White.

B) 9...�e7

As it turns out, White cannot make anything of the exposed position of the Black queen and attacking it merely drives it to better squares. If White instead retreats his bishop to f4, he has wasted a tempo and to little purpose, positionally. Conse­ quently the bishop swap is indi­ cated, and although this may improve the position of Black's queen, the burden of proof rests with Black as to how he can cover the black squares after the pawn break ... f6, ef6.

This is the critical test, since Black's queenside pieces are much better placed to cope with the kind of counterplay generated by White in earlier examples, when Black has dared to grab the pawn.

White probably can't hang about with moves such as 1 2.'iYd2 be­ cause of 1 2 ... a6, which shuts out the White knights.

Black will find that the position is not so easy to handle, e.g. l l ...a6? is met by 1 2.'iYh5. l l . . .h6 gives White a choice between l 2.�f4 and l 2.l:i:e5, while l l . ..tLld3 1 2.'iYd3 �d6 1 3.'iYd5 favours White. This leaves one main op­ tion for Black.

1 1 ... �d6 1 2.�e3

In this way White attempts to ex­

ploit the position ofthe Black queen, which does not have many squares.

1 2... 'iYb4

1 2 . . .'iYa5 may be better.

While this move takes the pressure off the White e-pawn it neverthe­ less has merits: The black knight is on an active square, which not only prevents White's tt:la4 attacking the black queen, but both controls e4 and makes �d3 less attractive to White. The presence of the knight on c5 also indirectly weak­ ens White's b2 pawn further. Nor should Black be unduly worried by the pin �e3 since at worst he can simply retreat to d8.

8.tt:ld4 tt:lc6

Once again it's risky to play 8 ... 'ifb2 due to 9.tt:ldb5, when even after 9 ... tt:le4 Black is in extreme danger: 1 0.tt:lc7 Wd7 l l .tt:l7d5 tt:lg5 1 2.tt:lf6 Wc6 1 3.�b5.

9.�b5 �d7 1 o.�c6 �c6

This is the strongest approach, im­ proving the position of the bishop.

1 1 .0-0

If l l .tt:lb3, Black's bishop imme­ diately enters the fray with l l ...d4!

Black is two pawns up, but as usual White is better developed, has more space and is trying to desta­ bilise the position. Here are some possibilities:

1 5 ... h6

This might be best. 1 5 . . . tt:le4? 1 6.:\lal 'iYb6 1 Hi'a4±; 1 5 ...a6 1 6.tt:ld6 (unclear is 16.J::!. a l 'iYb6 1 7.'iYb l ) 1 6 . . . �d6 1 7.ed6 0-0 1 8 .cd5 (not 1 8 .�e7 dc4!), with interesting possibilities for both sides; 1 5 ... �e7 1 6.�e7 We7 17.cd5 with compensation for the pawn.

1 6.�d2 'i!Vd8 1 8.�c3 tt:le6

1 7.cd5

ed5

In the case of bishop moves White can play 1 9.tt:ld6 opening up the a l - h 8 diagonal and/or the ' e ' file. If 1 8 . . . tt:le4 White also gains the ad­ vantage with 19.'iYa4.

1 9.�a4 �d7 20.J:!.fd1

Although two pawns up, Black's position is clearly unenviable. Naturally, over the last few moves either side could have steered a dif­ ferent course and the variation merely indicates a sample line.

Survey FR 4.5

Summary

Many variations stemming from 6 ...'ii'b6 offer White good attack­ ing chances and lead to interesting and often complex positions, as shown above. As is frequently the case, White's threats tend to multiply when Black captures the 'poisoned' pawn. The fact is that players of all standards will be tempted to take on b2. Motivated by consistency, ignorance, self-belief, even fear (of missing the obvious), they will take the pawn. Some players may even base the capture on analysis ­ yes, seriously. The absence of an outright refuta­ tion of this capture is almost irrele­ vant. Familiarity with the resulting positions is the key issue in practi­ cal play. Players interested in obtaining the complete overview of main lines resulting from l .e4 e6 2.lLic3 d5 3.lLif3 can obtain it on floppy disk by contacting Mr Skelton directly at [email protected] and quoting 'Jackal Attack' (80 pages of analysis and games with diagrams), cost 5 pounds sterling, including postage.

Alekhine Defence Four Pawns Attack AL 8.10

A Future For The Alekhine? 1 .e4 ti:Jf6 2.e5 ti:Jd5 3.d4 d6 4.c4 ti:Jb6 5.f4 deS 6.fe5 ti:Jc6 7.�e3 �f5 8.ti:Jc3 e6 9.ti:Jf3 �g4 1 o.�e2 �f3 1 1 .gf3 �h4 1 2.�f2 �f4 13.c5 The Alekhine Defence is not as popular as it used to be. According to the current theory, the position after l .e4 ti:Jf6 2.e5 ti:Jd5 3.d4 d6 4.ti:Jf3 is difficult to play for Black: both 4 ... g6 (Alburt) 5.�c4 and 4 ...�g4 5.�e2 as 4 ... de5 5.ti:Je5 g6 are said to be slightly better for White. Variations such as 4 ... de5 5.ti:Je5 ti:Jd7 (Larsen) 6.ti:Jf7 ! ? and

STATISTICS

4 . . . ti:Jc6 5 .c4 ti:Jb6 6.e6 ! ? are probably a bit too wild for most players. Facing De Firmian (who is not un­ familiar with the opening) earlier this year in Malmo, Timman (who also has played the line in the past) was confronted with the Alekhine Defence. Probably to avoid prepa­ ration, Timman decided to revert to the old Four Pawns Attack: 4.c4 ti:Jb6 5.f4. Timman relates in New In Chess Magazine 2001/5 that he was relieved when, after 5 . . .de5 6.fe5 �f5 7.ti:Jc3 e6 8.ti:Jf3 ti:Jc6 9.�e3, De Firmian didn't play one

of the sharper continuations, 9 ... �e7 or 9 ...�d7, but went for 9 . . . �g4 instead.

The Critical Line

The critical position in this line arises on the 13th move, after 1 0.�e2 �f3 1 1 .gf3 'ifh4 1 2.�f2 �f4. Timman played 1 3 .c5 ! - a 1 940 invention by the American Dr. Joseph Platz - and com­ mented: 'An important strategic feature of the text is that the pres­ sure against d4 is relieved and that Black cannot exploit his posses­ sion of square d5' . De Firmian reacted with 1 3 ... ti:Jd5, when White got a space advantage and the bishop pair after 14.ti:Jd5 ed5 1 5 .'ifd2. Black withdrew into passivity, trying to build a fortress. However, a mistake on the 24th move led to a virtually lost posi­ tion. This survey covers the position af­ ter Timman's 1 3 .c5 ! , examining both 1 3 . . . ti:Jd5 and 1 3 . . . ti:Jd7. It is clear from the Study Material that Black is living on the edge.

An Afterthought

Lastly, note the blitz game Tim­ man-Piket, Dordrecht 2000, in which Black (instead of 1 2 .. .'iff4) opted for 1 2 .. .'ifh3, a novelty as far as I can tell. Does this move have any future? 1 07

In the main game of this survey Sergey lvanov therefore resorts to the old line 6.de5 (instead of

After 7 ... d6 8.e6 fe6 9.ab5 ttJe7 l O.ttJc3 ttJf5, his opponent Emelin deviated from the game Nunn-Romanishin, Mexico 1977 (which is mentioned in all the theoretical textbooks) with l l .ttJd4 tLld4. Black did al­ right in this game, but Ivanov might have missed a promising continuation on move 13. New de­ velopments in this line are in the air. It is nice to observe the possi­ ble revival of an old variation the roots of which are to be found in the 1 9th century. All important games, old and new, are listed in the Study Material. One should take special notice of

Halprin-Pillsbury, Munich 1900, a very elegant game and relevant to this day. However, the whole line is rather drawish as well, especially if Black refrains from the ambitious 7 ... d6 and plays 7 ... ttJbd4 instead, returning the knight in a safe and simple way.

I hope this article at least contributes to the theory of the Open Variation of the Ruy Lopez.

l l ...t2ld3 can be tried too. On 1 2.lle3, 12 ... t2lcl was played in the junior game Bratovic-Smeets, Halkidiki 200 1 . I also checked the surprising and untested 1 2 ... t2lc5, thinking of an early d4 and insist­ ing on ... t2le6 and ... �c5. I did not find anything wrong with it. Yona Kosashvili beat Haba (Haifa 1989) in a nice game featuring l l ...t2lb3, but after 1 2.t2lb3 �e7 1 3 .'iVd3, 13 ... �f3 ! ? might be playable.

Conclusion

All in all, it seems Black can play this line. Several times in this opening my ideas did not work in the end, but I hope it's different this time. If I am mistaken, please forgive me and remember that even Anand came up with a losing line. I do not think he would have risked a line knowing it had a hole in it against Peter Svidler, but I am absolutely sure he would not have done that against Kasparov in a world championship match.

Afterthought

You may wonder why this article is called The Last of the Mohicans. Here is the explanation. Nowadays a player either makes very good results or has to play so much that he has no time to obtain a big encyclopedic knowledge of chess. In the old socialist system in Hungary, once a player got to a decent IM level, he could make a nice living out of chess despite having only modest results. That resulted in a situation in which some players did not bother to make good practical results, and could still work with chess. I could name a whole series of players: Haag, Dely, Petran, Hazai. Recently I realised I am the last of those players. Our chess careers were a waste to a certain extent, still maybe we added a bit to chess.

Queen's Gambit Declined Blackburne Variation Q0 1.5

The New Trend: 6 1 .d4 d 5 2.c4 e6 3.tt:lc3 .1i.e7 4.tt:lf3 tt:lf6 5 ..1i.f4 0-0 6.e3 tt:lbd7 7.c5 Introduction

The popularity that the 5 ..1i.f4 sys­ tem in the QGD has enjoyed for years is still rising. The opulence of its contents and the variety of its options have induced many players to include this system into their repertoires. White has the option to either play a quiet and controlled game striving for a small advantage without risk or to give the game an extremely sharp course in variations in which he castles to the queenside. One sel­ dom finds a variation in any open­ ing with such diametrically opposite and extreme options. The fact alone that these options exist commands respect and which option will be chosen natu­ rally depends on the individual player, and is caused by various factors. The analyses of several variations extend well into the endgame as can be seen in Pelletier's superbly written survey in Yearbook 58. In the search for new paths, Black players have recently more and more often developed the knight to d7 (6 ... tt:lbd7), instead of the standard 6 ...c5 and ... tt:lc6. The idea is not new but it has not

...

been sufficiently investigated. The different position of the knight gives the variation an independent character, and more recent exam­ ples from practice show this alter­ native to be quite playable for Black. Of course, it cannot be claimed that the knight stands bet­ ter on d7 than on c6, but it cannot be disputed that for Black this is a solid option if he wants to avoid the much-trodden theoretical paths. After 6 .. .tt.ibd7 the reaction . . . c5 still remains Black's main idea, but the more modest option ... c6, after which there appears a kind of a Carlsbad structure, also has its

lbbd7

adherents. However, this survey does not deal with the positions arising after ... c5. Postponing this move gives White the chance to block the position by playing 7.c5 himself, and that is the subject matter of our discussion. At an early stage of the game White relinquishes the tension in the center and claims space on the queenside. Obviously it is more consistent to play this move after Black has played . . . a6. Neverthe­ less, with the present structure the plan of advancing queenside pawns supported by the dark­ squared bishop has its sound posi­ tional basis as well. The idea has

STATISTICS

1 29

been known ever since the last century (Steinitz-Chigorin, Nurn­ berg 1 896), and I believe that it is this option for White (7 .cS) that was the main reason why the con­ tinuation 6 ... l/Jbd7 was for a long time overshadowed by the popu­ lar 6 . . . cS. Black players wandered for many years trying to find the right plan. The fashion of the 60ies was active play on the kingside as the obvious reaction to 7.cS. But, this straightforward plan, which neglects the development of the queenside, proved wrong. Several illustrative examples can be found at the beginning of the Study Material. The modern way to play against 7.cS is based on a different con­ cept. Black in the early phase of the game provokes and under­ mines White's advanced pawn mass with ... b6 and . . . aS with a clear and most important strategic idea in mind, viz. to exchange his light-squared bishop along the a6-fl diagonal. There are two dif­ ferent versions of this plan.

The system with 7

...

c6

In the variation 7 . . .c6 Black ig­ nores the white dark-squared bishop and at once carries out the plan ... b6, aS, �a6. The exchange of light-squared bishops is inevita­ ble. There are finesses regarding the moment of the exchange. Black should not hurry and, in the main line 8.�d3 b6 9.b4 aS l O.a3 �a6 1 1 .0-0, he should better play a couple of useful moves like �c8 and h6 for example, and wait for White's �c2 (or �e2) before he takes on d3. The best move order can be seen in Van Wely­ Kasimdzhanov, Vlissingen 200 1 . The positions that arise here are of a positional nature. White has a spatial advantage and his atten­ tion is directed towards Black's only permanent weakness - the c6 pawn. Playing for that pawn is the motif in all types of possible end­ games. In this variation these can often be knight endgames be1 30

cause Black has at its disposal the manoeuvre . . . �d8-c7 with which he gets rid of the unpleasant pres­ sure of White 's dark-squared bishop. White needs to be patient and he should be prepared for a long battle. The attempt to refute Black's strategy with an early b4-bS has not given satisfactory results in practice. Black has tac­ tical defensive resources at his disposal where he sacrifices ma­ terial for excellent compensation, as in the example I.Sokolov­ Spassky, Malmo 1 998. The black position is a tough nut that cannot easily be cracked with b4-bS, as can also be seen in the game Dreev-Malakhov, New Delhi, 2000. Although White carried out this breakthrough with the ideal arrangement of his pieces, Black resisted the pressure. But the mo­ tif b4-bS is always present before Black himself reacts with . . . bS, so he should be careful. The basic position for the con­ tinuation 7 . . . c6 arises after 8.�d3 b6 9.b4 aS l O.a3 �a6.

It would be consistent for Black to play ... b6-bS only when he really has to because of White's threat b4-bS. White often voluntarily abandons the a-file and by threat­ ening the breakthrough along the b and c-files, forces Black to close the position with ... b6-bS. In this type of the position matters can take an unfavourable turn for White if he underestimates Black's minimal tactical possibili­ ties which consist of the coordi­ nated exploitation of the a-file and e4 square. The transformation of the position after the possible ex­ change on e4 gives Black a power­ ful stronghold on dS. The consequences of such a transfor­ mation can be seen in the featured game Dautov-Kasimdzhanov, Es­ sen 200 I . This motif also comes to the fore in the important game Galego-Vaganian, Ohrid 200 1 , where Black won the theoretical duel with the promising novelty 1 4 . . . l:!.a7. Generally speaking, in the varia­ tion 7 ... c6 there is a balanced rela­ tionship between the arrangement of pieces and pawns, where even a small imprecision can easily un­ balance the position with serious consequences.

The system with 7 l/Jh5 ...

Similar strategic observations can also be made with regard to the variation 7 ... l/JhS. Sooner or later the a-file is opened, and which side will profit from that depends on various factors. In the case of the general exchange of the rooks along the a-file Black should make sure to prevent White in time from endangering the vul­ nerable c6 pawn. A careless treat­ ment is seen in Topalov-Karpov, Monaco rapid 2000. Black should not hurry to commit himself with his b-pawn because ... b6-bS gives White the possibility of the ma­ noeuvre l/Jd2-b3-aS, while the po­ tential bcS releases the b4 square.

Here Black at once eliminates the strong white dark-squared bishop, which in the main line enables him an active game, i.e. the exchange of the rooks along the open b-file.

Survey QO 1.5 Unlike the variation 7 ... c6, where we see knight endgames, here there often arises the type of the endgame tt:ltt:l versus tt:l�. White retains a space advantage, but with precise play Black is able to main­ tain the balance. It is advisable to study the finesses of this endgame type through two examples from Vaganian's practice: Schandorff­ Vaganian, Germany Bundesliga 2000/01 and Bareev-Vaganian, New Delhi 2000. It should be noted that in this second example Black did not apply the usual plan of opening the b-file but instead borrowed the plan from the system 7 . . . c6, which quickly yielded him equality. Finally, the question should be asked which of these two plans is the more reliable for Black. It is difficult to give a precise answer. The greatest expert on this varia­ tion, Rafael Vaganian, plays both of them, which could indicated that the choice is a matter oftaste. The continuation 6 . . . tt:lbd7 ap­ pears more or less often in the practice of top QGD experts like Kramnik, Karpov, Vaganian and others. This is a clear indication that one can expect an increase in popularity of this continuation in the future. Who should and who can success­ fully play this variation? Defi­ nitely not those striving for attacking chess and those whose endgame technique leaves some­ thing to be desired.

As Matthew Sadler explains in his remarkable

prize-winning book Queen 's Gam­ bit Declined: 'White often plays .ig5xf6 just to prevent the knight from coming to e4. Although this gives up the bishop pair, it drags the bishop from the f8-a3 diagonal where it belongs (on f6, it merely bites against the granite on d4).'

Black's Intentions

It's now clear what Black has in mind with the idea of 7 ... .id6, followed by ... lt:lf8 and ... lt:lg6. He would like to trade White's dark­ squared bishop, while at the same time keeping its counterpart on the best possible square - from d6 he's supporting active kingside play

and controls the b4 and c5 squares. This idea is not very well known. Suffice it to say that neither Sadler nor Lalic even mention it in their latest QGD-monographs. The Yugo­ slav Encyclopaedia does give some material which traditionally ends with � or oo. Its main protagonist was Ljubomir Ljubojevic, who took it up in the mid-seventies. After 7 ... .id6 8 . .id3 lt:lf8 White faces a choice between two princi­ pal options: 9.'il'c2 and 9.lt:le5 ! Other moves, such as 9.0-0 and 9. iY a4 have also been seen.

Variation A

Although it is not easy to get an ad­ vantage for White, 9. 'iVc2 is by far the most popular choice here. This is partly due to various transpositions, in which '/Wc2 has been played prior to move 9. After 9 . . . lt:lg6 (9 ... lt:le6 10 ..ih4 g6 is also worthy of attention, see Sokolov-Milov, Amsterdam 2000) White is at a crossroads: is it going to be 10.0-0-0 or 1 0.lt:lh4 ( 1 0.h4 and 10.h3 are just inferior versions of 1 0.0-0-0) A 1 ) 1 0.0-0-0 leads to unclear complications after 10 ...h6 1 l ..ig6 ( l l ..if6 'il'f6 1 2.e4 lt:lf4 1 3.�b1 is interesting, Miladinovic-Cvetkovic, Kavala 1 997) 1 1 ... hg5 1 2.lt:lg5 fg6 1 3.'/Wg6 �d7 14.lt:lf7 'il'e8 1 5 .lt:lh8 '/Wh8. Playing such types of posi­ tions is not everybody's cup of tea.

Survey QO 1 1. 4 A2) 10.tbh4 leads to some ad­ vantage after 10 ... 0-0 1 1 .0-0-0 h6 1 2.tbg6 fg6 1 3.�h4 g5 1 4.�g3 �g3 15.hg3 tbg4 16 . .!:i:d2, Bagi­ rov-Taimanov, Balm 1 977, and Stohl-Cvetkovic, Vmjacka Banja 1 989, when White will open the position with e4. However, Black has a strong alternative in 10 ... �e7 ! 1 1 .tbf5 �f5 1 2.�f5 0-0 ( 1 2 ... tbd7 13.�e7 tbe7 was Razuvaev-Smagin, Tashkent 1 984) 1 3.0-0 tbe8 1 4.�e7 W/e7 1 5.tbe2 tbd6 with good play in Hertneck­ Pinter, Germany 1 997.

Variation B

Now we finally come to the main subject of this survey. 9.tbe5 ! is a real hammer blow to Black's posi­ tion. When Black first faced it, he went pawn hunting with 9 ... 'iVb6. It proved to be an unfortunate choice, but it enriched the antholo­ gies of chess miniatures with Yusupov-Nogueiras, Montpellier Candidates 1 985 and Hjartarson­ Ljubojevic, Tilburg 1 989. By the way, ECO gives 9 ... 'iVb6 10.0-0 W/b2 l l. .l:i:c 1 tbg6 1 2.f4 0-0 1 3 J:Ic2 (Timman-Ljubojevic, 5th match game, Hilversum 1 987) and now 1 3 ... W/a3 as , concluding that 1 4.�f6 gf6 1 5.tbg4 �g4 1 6.W/g4 �b4 is :f. It doesn't take inhuman efforts to realise that Black can resign after 17.f5 �c3 1 8.fg6 fg6 1 9.�g6. Black does have an alternative in 9 ... W/e7, the choice of Ljubojevic in his game against Portisch, Nik­ sic 1978. Black's position proved resilient in the complications after 10.f4 h6 1 1 .�h4 g5 1 2.fg5. Dizdar-Groszpeter, Austrian Staats­ liga 1 999, is another example where a draw was reached. But the situation becomes less rosy after the superior 1 2.�g3 ! After 1 2 ...gf4 1 3.ef4 tbg4 we can continue with 1 4.0-0 (as in the main game) or play 1 4.W/e2 ! , sim­ ple but strong. The point is that 14 ... llg8 1 5.0-0 f6 1 6.�h4 ! com­ pletely paralyses Black's position. During the game I overlooked this possibility.

In our main game Laurent Fressi­ net played 1 4 ... �e5, a bad novelty. He didn't take enough time to real­ ise (it was a rapid game) that there is a huge difference between our game and Relange-Prie, Clichy 1 995. 14 ... tbe3 seems better, since it is not clear why Prie didn't ex­ change queens in reply to 1 5.Wih5. However, I believe that in the case of 14 ... tbe3 White strikes at the other side of the board with 1 5.W/a4 ! , which yields him excel­ lent chances. At the end of this survey you will find some games with 9 ... tbg6. Blagojevic-Cvetkovic, Yugoslavia 1 999, shows us what Black should be aiming for. With the novelty 1 4 ... tbe4! Cvetkovic improved on an earlier game of his against Chemin, Belgrade 1988. I feel White should have played more aggressively against Black's cramped position. The immediate 1 2.h4 is probably over-optimistic, but 1 2.0-0-0, followed by that same idea of h4, looks dangerous for Black.

Meeting The Aggressive 6.tbh4 1 .d4 d5 2.c4 c6 3.ttlf3 tt:lf6 4.e3 .tf5 5.tt:lc3 e6 6.tt:lh4 A remarkable new trend in the Slav Defence is the rising popular­ ity of the line 3.ttlf3 tt:lf6 4.e3 which used to be considered to­ tally harmless after 4 . . . .tf5 . Although this is undoubtedly still the most critical move, several high-level games have shown that White's chances should not be un­ derestimated if he continues in the most aggressive way, which is 5 .tt:lc3 e6 6.tt:lh4. Now 6 ... .tg4 was examined by Dautov in Yearbook 60. After 6 ... �g6 or 6 . . . .te4 7.f3 .tg6 (it is

not quite clear which is best, al­ though 6 ...�e4 is certainly more popular and has also scored better) White continues 7.�b3 (or 8."ifb3) when Black faces an im­ portant choice. The endgame which may arise from 7 (or 8) ... "ifb6 turns out to contain more venom than anyone ever thought, now that the likes of Kramnik have taken up the White side of it. The main alternative 7(8) . . .'i/c7 leads to more complicated play, often producing the typically Slav situation where Black is a little cramped for space, but he has a solid position with counterplay looming in the background.

What is really very attractive for White in this line is that there are few forcing lines, which after a while, tend to kill any theoretical debate. Instead there seems to be ample scope for a slowly develop­ ing middle game which makes high demands not just on your opening preparation, but even more on your practical skills, which is what chess is all about.

Black is quite solid against a direct attack, though, and he usually cas­ tles kingside too, organizing coun­ terplay in the centre afterwards. It is quite amazing that the most popular move is 9.Jl.e3, and not 9.0-0. e3 is the best place for White's bishop, of course, but on the other hand I don't really see why White should start with this move. 9.0-0 is quite logical White executes the plan with 'it>hl

and l:i:gl first. Later on, in some lines the bishop might go to h6 di­ rectly. Anyway, if White plays Jl.e3 soon, this aspect might make no difference. In the featured game against Alexey Shirov from the German Bundesliga 200 1 , I tried to postpone the move Jl.e3 as long as I could, intending to play it only when there was a direct threat against pawn d4. My main task was to organize a quick attack on the kingside and I believe this is what White should do in such posi­ tions - play actively by trying to use his bishop pair and the g-file, see Mikhalevski-Rabinovich, Dieren 1 999, or Izeta-Stefanova, Las Pal-

mas 1996. But as I said earlier, Black has a solid position and White can easily end up with a bad pawn structure and no attack. I refer to Cebalo-Lugovoi, Budapest 1 996 and Omearat-Rausis, Cairo 200 1 . White's alternative, to start active play at once with 9.l:i:g 1 (or Jl.e3 and J::!.g l with the king on e l ), is probably too optimistic and rather dubious. The move 9.Jl.a6 is better, but I believe that Black has enough counter-chances after that. So the plan involving kingside castling (with or without Jl.e3), followed by 'it>hl and .!lgl is White's most promising approach and it might cause Black serious problems.

Tarrasch Defence Rubinstein Variation TD 4.16

The Right Rook 1 .d4 d 5 2.c4 e 6 3.t2:lc3 c 5 4.cd5 ed5 5.t2:lf3 t2:lc6 6.g3 t2:lf6 7.�g2 �e7 8.0-0 0-0 9.�g5 cd4 1 0.t2:ld4 h6 1 1 .�e3 J::l:e8 1 2.'il'a4 A Difficult Choice

In the Rubinstein Variation of the Tarrasch Defence, White faces a difficult choice after 12. 'iVa4 �d7. Which rook to move to d l ? Tradi­ tionally White has preferred 1 3 . .!:!:ad l . The reason is that his piece coordination is not disturbed after 1 3 ... t2:la5 14.'il'c2, and now a future t2:lc4 is easily answered by �c l , and as the a l -rook has been moved to d l it will not be stuck in the corner. Since 1 3 ... t2:la5 is bad, Black must react with 13 ... t2:lb4 1 4.�b3 a5, when he gets good counterplay. So far so good. So why is 1 3JHdl not White's most popular choice, you may ask? The reason is that now the above argument may be turned around. This time 1 3 ... t2:lb4 is no good because of 14. �b3 a5 1 5 .t2:ld5 when after all the ex­ changes on d5 Black does not have �h3, winning an exchange, since the fl-rook has been moved to d 1 ! This trick has been known since the game Vaganian-Ivkov, USSR­ Yugoslavia 1 975 (see the notes to the main game). Hence, tradition­ ally Black has replied with 1 3 ... t2:la5 reasoning that a future 1 66

t2:lc4 will now seriously embarrass White's dark-squared bishop.

Lautier Revives Keilhack

Enter Lautier, who has shown in a recent game against Grischuk, Enghien-les-Bains 200 1 , that there is no need for the bishop to move at all. For White gets a pleasant edge after 1 3.J:Hd l t2:la5 1 4.'iVc2 t2:lc4 1 5.t2:ld5 ! t2:ld5 1 6�d5 t2:le3 1 7.fe3, when Black has not enough compensation de­ spite his bishop pair. Was this sur­ prising novelty perhaps found with the aid of a materialistic

computer program? Hardly so, it is actually more surprising that this has not been played before in a top-level game, because the move 1 5 . t2:ld5 ! had already been suggested by Harald Keilhack in 1 993 in his seminal work on the Tarrasch ! In fact, Lautier­ Grischuk bears a remarkable resemblance to Kelecevic-Wein­ zettl, Wattens 1 988 ( 1 3.J:Iad l ) - a fine effort by White.

Conclusion

The whole 1 2.'iVa4 line is quite concrete. White simply prepares to

attack and win the isolated pawn. Therefore, Black's counterplay is often also based on some very con­ crete tactics. I have already men­ tioned that White must carefully check the tactics when he takes d5 (see Vaganian-Ivkov, but also Olafsson-Nunn, Groningen 1 974 - 1 3 /i:JdS?). The positional ex­ change sacrifice on e3 is another typical feature that he must avoid (see Paunovic-Poulenard, Mont­ pellier 1 989, and Ljubojevic­ Bosch, play-off Dutch Team Championship, Breda 1 999). Black's main worry is that he sim­ ply loses d5, but he may also lose after a quick kingside attack (see Gurevich-Summerscale, France 1 999). In conclusion, 1 3 ..1:Hd 1 is stronger than 1 3 . .l:!.ad 1 , as the former neu­ tralizes Black's counterplay quite effectively. For the moment, the onus is clearly on Black.

Ql 1.1

And The Beat Goes On 1 .d4 tt:lf6 2.c4 e6 3.tt:lf3 tt:lc6 4.a3 The Black Knights Tango ( l .d4 tt:lf6 2.c4 tt:lc6) has received con­ siderable practical exposure since my treatise in Yearbook 4 1 . Sev­ eral grandmasters, most notably Yermolinsky, Benjamin and Bolo­ gan have played the line success­ fully against very solid opposition. It's fair to say that 3.tt:lf3 e6 4.a3 remains the best choice for the first player. Black's options are 4 ... d6 and 4 ... d5. The second line was tested a few years ago in Kasparov-Yermolinsky, Yerevan Olympiad 1 996, where the former

STATISTICS

World Champion obtained a edge out of the opening. While 4 ... d5 remains playable, 4 ... d6 has emerged as a very strong alternative. The original inventor of the system, Viacheslav Che­ banenko, preferred 4 ... d6 on ac­ count of its originality. Moldovan grandmaster Viorel Bologan (who incidentally was among the group of remarkably talented youngsters I was coaching together with my then good friend V. Chemov for a short period of time in Moldova) has been an active and successful promoter of this system. A summary of challenges Black is facing after 4.a3.

4. . . d5

Here 5.tt:lc3 remains popular, al­ though Neverov's idea 5.e3 g6 (5 ... dc4 ! ? 6.�c4 �d6 ! ?) 6.b4! �g7 7.�b2 tt:le4 8.tt:lbd2 is inter­ esting. I believe there are no prob­ lems for Black after 5.cd5 ed5 6.�g5 in a view of 6 . . . �e7 7.tt:lc3 tt:le4 (see Gentes-Orlov, Vancou­ ver 200 1 ). After 5.tt:lc3 main lines are 5 ... g6 and 5 . . .�e7. Kasparov put some problems before second player after 5 . . . a6 (Silman) 6.cd5 ed5 7.�g5 (as in Kasparov­ Yermolinsky). The lines after 5 ... g6 6.�g5 �g7 7.e3 h6 8.�h4 0-0 9.�d3 look more favorable for White. In case of5 ... �e7 6.�g5 h6 7.�h4 tt:le4 the resulting position is playable for Black. I have not seen many games with 6.�f4, but this move is not to be underesti­ mated.

4. . .d6!?

Bologan has played this move with a great deal of success. The main line here is 5 .tt:lc3 g6 ! ? It's fair to say that 5 ... �e7 6.e4 e5 7.d5 tt:lb8 8.�e2 gives White a small edge. While the position is closed and thus the loss of time on ttJb8-c6-b8 and e6-e5 is less felt, it's neverthe­ less substantial. While White's victory celebration is, by all means, uncalled for, playing this line is a risky business for Black. 1 75

Further, 6.e4 Ji.g7 leads to position similar to the Classical Variation of King's Indian. The games where White played 7 .Ji.e2 0-0 8.0-0 brought him little success af­ ter 8 .. Jle8 ! ?, followed by e6-e5. Another idea, 7.h3 0-0 8.Ji.g5 ! ? was recently introduced by Stuart Conquest against Bologan and later repeated in the featured game Krasenkow-Bologan, Shanghai 200 1 . White provokes h7-h6 and retreats to e3, making h6-pawn vulnerable to a later attack. In ad­ dition, White develops his queen's bishop to d3 instead of e2, cover­ ing the crucial e4 square. Bologan drew both games, but in his com­ ments to Krasenkow-Bologan he suggests l l .Ji.e2 ! ? as an improve­ ment, allowing White's queen to protect the important d4 square. While this suggestion is certainly very sensible, I feel we have not seen the end of Black's efforts in this line.

Minor Lines

White seldom opts for an early ad­ vance of his queen's pawn after 5.tt:lc3 g6. Not much material is available on 6.d5, only Khari­ tonov-Brodsky, Koszalin 1 999, proceeded in this direction. The final position of that game appears to be balanced. Another sensible idea for White is 6.g3, hoping to make use of the tempo a2-a3 in later developments on the queenside, although I can­ not quite remember any King's In­ dian line other than the Classical where the expansion with b2-b4 is successful for White. Both in Sorokin-Poluliakhov, Novgorod 1 999, and Bonin-Benjamin, Sara­ toga Springs 2000, Black success­ fully deployed 8 .. J:!:e8 ! ?, once again intending to meet e2-e4 with e6-e5 and tt:lc6-d4.

White moves his rook away from the X-ray of �g7, then plays b3, neutralising Black's typical plans ti:lb6-c4 or �c4. The variation has been extremely popular in the past two years and Black has to play very precisely to retain his chances for active piece play ! After IOJ:!:bl ! ? 0-0 1 1 .0-0 ti:lb6 1 2.b3, Black can choose between two possibilities:

B ) 1 2 ... �b7 1 3.tl:lh4 ti:le8 ! ? was played in Milov-Tregubov, Deizi­ sau 200 1 , when Black played e6 and obtained satisfactory counter­ play in the centre.

(l3.b3 '®'a3 ! with good play for Black, as in Avrukh-Ponomariov, Batumi 1999) has been popular lately, when Black faces problems (see Yakovich-Calzetta Ruiz, Saint Vincent 2000 and Malakhatko­ Aveskulov, Alushta 2001). It can be concluded that l l ...ti:lb6 seems to give Black better pros­ pects than l l ... �a5 , which used to be popular earlier.

Old Indian Defence Main Line 8.�e3 01 6.10

The Right Time 1 .d4 tt:lf6 2.c4 d6 3.tLlc3 tt:lbd7 4.tt:lf3 e5 5.e4 �e7 6.�e2 c6 7.0-0 0-0 8.�e3 a6 This survey is devoted to the line that represents the origin of the King's Indian Defence, in those forgotten times when nobody knew such a name as KID ! The plan of developing the bishop to e7 looks more passive than a kingside fianchetto, but it gives Black sev­ eral advantages. The lines with the bishop on e7 have not been subject to so many theoretical investiga­ tions. Furthermore, if White chooses to close the center with d4-d5, it will be easier for Black to bring his 'bad' bishop back into the game via d8 and b6 or to swap it on g5. Thirdly, the pawn structure be­ comes very stable and steady. In this survey we will consider the position after 9.h3 b5 1 0.a3 �b7 l l .'i¥c2 J::!.e 8 1 2 .l:!Jd l VJ/ic7.

This position calls forth associa­ tions with several other openings. Apart from the above-mentioned KID, which closely resembles this Old Indian - especially after the exchange on e5 - one can observe similarities with the Philidor De­ fence. There is one very important difference, however. In the Philidor the c-pawn is still on c2, which requires a completely dif­ ferent plan from White, relying more on piece play in the center and on the queenside. In the Old Indian pawn structure White's plan is more likely to be oriented towards a queenside pawn attack

and the breakthroughs c5 or d5. The positions in this survey will often remind us of a Ruy Lopez structure (as in Petran-Lobron, Euro-Cup 1989 for instance), in which, after the exchange of c­ pawns ( 1 3 .cb5 cb5), White tries to exploit the weakness of the c6square and Black's inability to rap­ idly transfer his pieces from the kingside to the queenside, where the main battle is going to take place. Black's plan lies in the chance to exchange on d4 and break through with the typical thrust d6-d5. These and similar plans can be borrowed from the

Survey 01 6. 10

Ruy Lopez, especially the Breyer, Zaitsev or Smyslov systems. It seems White has to close the center at some moment in order to prevent Black from executing his plan and to carry out his own, but the main question of this entire line is: what is the right moment to do so? Because if d5 is played too early, Black may be able to close the center with c5 and to create some counterplay on the kingside. Another drawback of an early d5 lies in the fact that White himself might not yet be ready for the queenside attack. In order to pre­ pare queenside play, it is reason­ able for White to postpone d5, but if he delays it for too long, Black might be able to materialize his plan first. In the main game of the survey (Shulman-Krechetkov, San Fran­ cisco 200 1) White tries to prove that Black's plan is going nowhere and that it White need not play d5, as Black's attempts of freeing him­ self after ed4 and d5 do not prom­ ise complete equality.

The only sensible move with the c3 knight is 3.i>g7 31 .tLle7 .li:b6 32.tLlg6 'ilo>g6 33 .ilf6 >i>h5 34.h3 t2Je3 35 . .!:r.e1 lLld5 36.g4 >i>h4 •

English Opening Symmetrical Variation EO 32.3

No Cure Yet 1 .c4 c5 V2:lc3 tZ:lc6 3.tLlf3 t2lf6 4.d4 cd4 5.tLld4 e6 6.g3 �b6 7.t2ldb5 t2le5 Prelude I had only a few days to prepare for the category 1 3 tournament in Kharkov, which was to take place in the second half of April. When hastily going through my oppo­ nents' games, I noticed that several of them used to react to the English Opening with the symmetrical set-up l .. .c5, 2 . . . t2lf6 and 3 ... t2lc6. So, logically, I decided to try and find a line that would bother them a bit. My quest resulted in the variation examined in this survey.

STATISTICS

The Line At Stake I will concentrate on the position arising after 7 ... t2le5. Presenting the subject in Yearbook 45, Kick Langeweg evaluates 8.�f4 as 'unable to lead to any advantage' . This assessment is still valid, as long as Black replies 8 . . . t2lfg4 9.e3 a6 - see for instance L.Hansen­ C.Hansen, Aalborg 2000. Surpris­ ingly enough, alternatives to 8 . . .tLJfg4 quickly lead to difficul­ ties: 8 . . . �c5 is well met by 9.�g2 ! (Bruzon-Volokitin, Lausanne 2001), and 8 ... d6 ended in a disaster for Black in L.Hansen-De Firmian, Denmark 1 998. After 8.�g2 a6 9.�a4 deviations

from the main move 9 . . . l::!.b 8 have not been popular lately, although in my opinion 9 ...t2lfg4 and 9 ... t2Jeg4 are worthwhile too. This leaves us with the ending arising after 9. �a4 l::!.b 8 10.�e3 �c5 l l .�c5 �c5 1 2 .�a3. Black has now two ways of trading queens: 12 ... �a3 or 12 ... b6. When prepar­ ing for Kharkov, I understood that Black does not have any trouble after 12 ... b6 13.�c5 bc5 14.tLJd6 ri;;e7 1 5.t2lc8 :C:hc8 1 6.b3 g5 !, as first played by John Emms. Recent games confirm this conclusion. The alternative 12 ... �a3 1 3.t2la3 is less drawish. Here I managed to find an improvement over former games, where White regularly al­ lowed ... t2lb4. I have to admit that I have never been as lucky when try­ ing to guess my opponent's open­ ing choice as in Kharkov ! Both Ruslan Ponomariov and Pavel Eli­ anov followed my preparation and experienced problems. Those en­ counters constitute the main games of this survey.

Conclusion It seems obvious to me that Black is doing all right in this variation if he continues with 1 2 ... b6 and later 16 ... g5. 16 ... d5, which was the novelty of Yearbook 45, is also in­ teresting but less secure. In fact, I do not see any perspective to play 21 1

for a win as White after the king­ side has been blocked with g5 and h5 . In case Black wants to spice up his day a little bit, he can always in­ vestigate alternatives at move 9. To sum up: White definitely needs to find something new!

Monographs Lev Alburt & Alex Chemin Pirc Alert! A Complete Defense Against l.e4

As a service to our readers the editors keep a close eye on all issues on the subject of the chess opening. Publications in any form, (e.g. books, CD-Roms and videos) may be the subject of a review in this section.

Uncredited reviews are by the NIC editorial board. All publications mentioned are in English unless otherwise indicated.

Chess Information and Research Center 2001 448 p. $ 34.95 This is not your average opening book. It is not just a book about the Pirc, or only a complete defence against l .e4 (although that in itself is quite an achievement). This book is also about a certain method of working on the opening, and more importantly still this book will teach you about chess. It de­ serves to become a classic, and it also deserves quite some review­ ing space. Now that I have given you my very positive overall evaluation I can safely start with some minor criticisms. When you casually flick through the book you may be shocked by the colourful (black and blue) presentation. What is more, I sus­ pect that quite a few non­ American readers will have to get used to its 'self-advertizing' style. The authors (Alburt) boast about their achievements in true Ameri­ can(?) fashion. I personally won­ dered why they felt the need to pat themselves on the back. I trust this is for commercial reasons - 'buy this book'. However, just reading the names of the authors on the jacket should convince many

chess players of the value of this book. Two strong and serious Grandmasters, one of them clearly a supreme Pirc expert. When the names mean nothing to you, then the contents of the book, even at a casual glance, should convince many a skeptical buyer. Coming back to the black and blue presentation. This book has a strong didactical side. Ideas are extremely well explained. They are first touched upon, then worked out, and finally summa­ rised and repeated. The authors make admirable use of presenta­ tion techniques here. There are many diagrams, the blue ones indi­ cating the most important posi­ tions. General ideas and guiding principles stand out in large type within blue boxes. To give a few examples of such guiding princi­ ples: 'It's best for Black to play ... c7-c5 or ... e7-e5, inviting White to push d4-d5 rather than e4-e5.' (p.37), 'Pressure on e4 is a key idea for Black in the Philidor Pirc.' (p.86), 'In the Philidor Pirc, we should look to trade off the c8bishop.' (93). Such rules of thumb are conducive to the learning pro­ cess and clearly enrich this book. Unfortunately, the tendency to have blue boxes every few pages leads to a number of superfluous and even annoying 'guide lines' . Surely it is not helpful for the reader to know that 'Lev Alburt, after only a few lessons in the Pirc

from Alex Chemin, found a move that changed the theoretical as­ sessment of a key variation ! ' (p.223), nor does the general state­ ment 'Black has compensation for the exchange' (p.254) which refers to a specific position deserve to stand out in a blue box.

The Structure of Pirc Alert! The book is divided into three main parts. Part I (written by Alburt) de­ scribes in a personal account how this book found its authors, and, more importantly, how this book should be used. The next two parts form the bulk of the book. They are mainly written by Chemin as the Pirc expert (although he was appar­ ently assisted by Alburt in part Ill ­ the exact division of roles is not clear here). Part 11 explains the gen­ eral themes and ideas of the Pirc in slightly less than 200 pages ! Thus the main structures are explained as well as the most important ideas for White and Black. Important strate­ gical operations are highlighted: such as, which pieces to trade and not to trade, playing for c5 or for e5, releasing the tension (ed4) or not, and so on. Finally, the third part gives you the theory of the Pirc, or at least those variations selected by Chemin for the reader. Some 230 pages divided logically into 5 sec-

tions (depending upon what gen­ eral idea White plays for) which are in turn divided into a total of 1 1 chapters. Each of these 1 1 chapters starts off with a one page overview with 4 diagrams preparing the reader for the coming discussion. Next there follows an introduction with some of the main ideas and important move orders and specific tactics. These sections partly over­ lap or repeat themes already ex­ plained in Part 11. However, repetition is an important didactic instrument and the reader will surely benefit from this approach. Only then do we get pages and pages of moves and analysis: i.e. the traditional opening book. Even here, though, this book compares favourably to others. Chemin gives his expert opinion on many lines. Indeed, he seems to be holding nothing back - a rare thing for an active grandmaster - even adding numerous TN's which are marked accordingly (in blue of course). The only drawback that I can think of is that this is a repertoire book written from the Black side. This means that not all lines are covered, but only those which Chemin deems strongest for Black against that particular line. The conse­ quence is that the book is less use­ ful for those who play against the Pirc. A danger for a black player is that if the particular line chosen by Chemin is not your cup of tea, or gets refuted in the future, you will have to look elsewhere for an alter­ native. On the positive side you might argue, as indeed the authors do, that the reader is saved a lot of time having to examine every sin­ gle line and trying to find out which is best. That time-consuming part of opening research has already been done by an expert, and he is willing to share his opinion!

Learning Chess: Part 11: General Themes and Ideas In Part I Alburt argues that the in­ tended readership of this book in­ cludes even those players who do

not play the Pirc and do not intend to take it up (p. 17). While this is tantamount to saying that every­ one should buy this book, I must confess that on the strength of Part 11 alone I do agree. Chemin does a great job as a chess instructor, and he certainly does not limit himself to the intricacies of the Pirc. Thus, he explains Nimzowitsch's theory of 'Overprotection' in a very clear and succinct manner.

This is a slight adaptation of one of Nimzowitsch's diagrams. Chem­ in's explanation is in fact more lu­ cid than Nimzowitsch's own from Mein System. In the above dia­ gram: 'The d4-outpost is attacked and defended by an equal number of pieces on both sides, and the situa­ tion can be characterized as a total paralysis of the defending pieces. ... So none of the White pieces in­ volved can undertake dynamic ac­ tions against Black's position.' (p.87) Next he adds a White rook on d3 and a Black on e8. This changes the situation, for 'now all the White pieces become dynamic, so that any one of the group - the f3knight, e3-bishop and even d3rook - are free to move and can take part in active operations. . . . Thus when White strengthens his outpost by adding more defending resources, he doesn 't tie himself down further. On the contrary, such reinforcements lead to posi­ tions where all White's pieces have more freedom.' (pp. 88-89) This is indeed what overprotection 223

is about, but I don't think I have seen it explained so well before. However, things will get even bet­ ter, for Chemin now makes the idea of overprotection valuable for a specific type of Pirc position which he calls the 'Philidor Pirc' (i.e. positions where Black re­ leases the tension with ... e5xd4). In such positions Black's single most important idea is to build up pressure against pawn e4. Chemin builds up his argument with the help of three diagrams. The first one is good for Black, the second one is good for White and the third one is dynamically equal.

Here White has overprotected e4, and Black therefore has no coun­ terplay and is clearly worse. This leads to the following success formula: 'the number of attackers against the e4-outpost must be no less than the number of defenders' (pp.89-90). This rule is rightly em­ phasized within a blue box. Finally, Chemin presents the theo­ retically important game Aseev­ Zakharevich where we find a case of dynamic equilibrium.

While the number of attackers and defenders equals out at the mo­ ment, it is also true that both sides have one rook in reserve for at­ tacking and defending e4. For an extensive analysis of this position, buy the book! Interestingly, Chemin later (pp. 1 1 2- 1 24) comes back to these games to discuss them in detail. This not only helps the reader to memorize the most important points, but, as I have argued above, increases the didactic value of the book. There is much more to be said about this Part. I am also quite im­ pressed with the number of well­ chosen illustrative games with which Chemin supports his argu­ ment. Another nice feature are the diagrams which illustrate a certain positional idea or higlight a strate­ gic operation. Take, for example, the following one (p. 1 0 1 , 108): How to recapture?

Aseev,Konstantin Zakharevich,Igor Elista ch-RUS 1 994 (2)

Black is better as White is tied down to the defence of e4, more­ over b4 is threatened.

Some Theory To give you a more specific idea of what these theoretical chapters look like we will now skim through one particular chapter called 'Chapter 17: The Classical System, I; Introduction & 5.�e2 ' . For reasons o f space I move di­ rectly to the theoretical variations in one particular line here (Varia­ tion B l , pp.3 10-3 1 3).

1 .e4 d6 2.d4 ti:Jf6 3.ti:Jc3 g6 4.ti:lf3 .ik.g7 5 . .ik.e2 0-0 6.0-0 �g4 This is Chemin's preferred choice, he mentions the alternatives 6 ... ti:lc6 and 6 ...c6 only in passing.

The choice for 6 ... �g4 and not 6 . . . c6 has been explained in Part 11: 'Not because 6 ...�g4 is actually stronger, but rather because there is a clear concept behind it' (p. l 29). Three lines are now discussed: A) 7.h3, B) 7.iLe3 and C) 7.a4.

B) 7.�e3 ti:lc6 Here Chemin divides the material in two main lines: B l) 8.'1Wd2 and B2) 8.d5. He rightly mentions that other moves cannot hurt Black, citing briefly: 8.�d3 e5 9.d5 ti:le7 1 0.ttld2 �c8 ! (TN), with the idea of ... ti:ld7 and ... f7-f5. This is one of the many instances where Chemin gives a novelty for free.

81 ) 8.'t'Hd2 e5 Now B l a gives the innocuous end­ game line 9.de5 deS l OJiad l . Here I like Chemin's recommen­ dation 10 . . . �c8 l l .'iVc l l:id8 1 2.l:Id8 ti:ld8 ( ! ) which is a simpler equalizer than the more common 1 2 ... 'iVd8 - which he does not even mention! Let us continue with B 1 b: 9.d5 ti:le7 1 0.J:!.ad1

meet f2-f4.' This is quite an inter­ esting suggestion, more so be­ cause it has hardly ever been played! It is just one of the numer­ ous valuable ideas that are casually dropped by Chemin. Still, his quite ruthless method of selection is another typical feature of this work. Thus, 1 0... \t>h8, 1 0... .tf3, 1 0 . . . ti:ld7, 1 0... ti:le8 and 10 ...b5 are not deemed worthy of receiving a small note or game reference. I, for one, am surprised that 1 0. . . b5?! - a move that became fa­ mous after Black's victory in Karpov-Azmaiparashvili, Soviet Championship, Moscow 1 983 - is not given. It is true that the theo­ retical value of this move is negli­ gible, however, its main ideas are quite close to those of 1 0. . . �d7 ! From a historical perspective the game is of some value for the whole line, and what is more Kar­ pov losing a game as White was quite a rare occasion in those days ! Here it is: 10 ... b5?! l l .a3 [We now know that l l ..tb5 is the refutation, both l l .. ..tf3 and l l ...ttle4 are insuffi­ cient] l l .. .a5 1 2.b4 ab4 1 3.ab4 l::ta3 14 ..tg5 [compare the follow­ ing exchange sacrifice (which can hardly be accepted) to the one be­ low in Brunner-Fioramonti]

1 1 ... b5! The exclam is Chemin's who con­ tinues to explain why l l ...ti:lg4 is no good here citing Nielsen­ Chemin, Taastrup 1 992, in the pro­ cess.

1 2.a3 aS 1 3.ti:ld3 This is the main line, Chemin also mentiones 1 3 .b4 ab4 14.ab4 lla3 1 5.�g5 ( 1 5 .f3 is also given) 1 5 .. J:tc3 1 6 ..tf6 .!:!.a3 17.�g7 Wg7 (here is the eerie resemblance to Karpov-Azmai) 1 8.f4 f6 1 9.ti:lf3 '1Wb8= (Chemin) as in Brunner-Fioramonti, Switzerland 1 992.

1 3 ... �b8 1 4.f3 c6 Again Chemin draws on personal experience to explain that 'Black doesn't need more preparation to perform a central break.' In Kuczynski-Chemin, Polanica Zdroj 1 992, White went for a strong pawn sac after 14 ... .!::!.d 8 15.b4 ab4 1 6.ttlb4! .ih3 17.lla l .

1 0...�d7! Black's strongest option according to Chemin, and I think we can safely trust him on that one. The bishop retreat is also the most popular move here. Yet, it is re­ markable, especially for an open­ ing tome of almost 450 pages, that only one other move is mentioned at this stage. I quote: 'Playing in King's Indian style with 10 ....tc8 ! also deserves attention, leaving d7 as a retreat for the knight on f6 for example, l l .ttlel ti:ld7 ! . Black is ready both to play ... f7-f5 and to

tournament in Bastia Chemin did very well. He made it into the final, not even losing to Anand. His three draws versus the Indian genius gave him second place overall. He held his own in a fashionable Pirc quite easily:

Jeroen Bosch

Anand,Viswanathan Chemin,Alexander After quite a long but impressive theoretical expose we have ended up with this, very unclear, posi­ tion. Considering the importance of this line, Chemin's conclusion is, uncharacteristically, vague: 'We've followed the game Kamin­ ski-Finkel, 1993' . . . 'Finkel recom­ mends 2 l .. .tLlfS, with good play for Black. The move 2l .'�c8, which was actually played in the game, looks worthy as well.' Both moves may indeed be good, and it may be true that Black has a good position. Yet, I would like to see how things might develop. It is true that we are on move 2 1 , so perhaps it is a bit much to ask of the writer of an opening book to continue his analysis here, yet I don't understand why the rest of the game is not given for the read­ er's benefit. So, here is the rest of that game: 2 l . ..Wfc8 ! ?

As an afterthought on this slightly critical note of mine the following lines (Alburt in Part I, Chapter 3, p.26) deserve to be quoted in de­ fence of the authors: 'Whatever your playing strength, nothing will improve your opening results more than home preparation - your own work in your own home over your own board.' So true, so true. ..

Chernin remains alert in the Pirc! In the recent (knock-out) rapid 226

volume sets high standards for the next two volumes, and gives this reviewer something to look for­ ward to. Actually, I wouldn't mind an extension of this series either. Provided that the same passion and effort is put into it: why not hope for 'Alekhine Alert ! ' with Alburt as its expert author?

Future Plans Pirc Alert! constitutes the first part of a projected three volume series on openings. Volume 2 will pro­ vide a complete defence versus all other first moves. While Volume 3 will give you a complete White­ repertoire. The quality of this first

Everyman 2001 176 p. £ 14.99 Byron Jacob's publication about the French classical is a must for everybody who wants to pick up 3.tt:lc3 against the French. The author delivers a complete overview of all the lines that can occur on the basis of 78 grandmas­ ter games that are thoroughly analysed. Practitioners of the French themselves I would just ad­ vise to buy this nice (but English and therefore rather expensive) book. As with any theory book from Everyman Chess, the advantage of the presentation by games is that the reader gets a grip on the strate­ gic, and sometimes tactical, ideas behind the opening. When he or she (unwillingly) enters unknown territory or simply forgets theory he or she should be able to cope

with problems ahead. The draw­ back of the approach is that it can take rather long before you have a good view of the opening and therefore the risk of mixing things up seems considerable. The author has managed to include some games from 200 1 in the book which is nice, not least because at least one of them was quite enjoy­ able for the writer of this review. The oldest game presented is Kaplan-Bronstein which took place as far back as 1975 but can still be studied without any risk for one's repertoire. Lastly, I would mention the some­ times inconsistent use of exclama­ tion and question marks by J acobs. I do not see the point of calling a move interesting (with ! ?) without giving alternatives, or giving a series of ! for Black and some ? ! for White when the position re­ mained equal. Jan van de Mortel

David Cummings Symmetrical English Everyman 2001 1 60 p. £14.99 'Symmetrical English, again?', I hear you think. Yes, with Vladimir Krarnnik in the driving seat the Eng­ lish Opening has regained its popu­ larity. Make no mistake about it, the English Opening is not just a dull,

cowardly opening to prevent your­ self from losing, not even the sym­ metrical English! One should realize that what one gets from an English Opening often is what one gets from the black side of a Sicilian Defence - dull, cowardly? I think not - with an extra move to spare! Less than a year ago, Carsten Han­ sen authored a bible that seemed to cover everything one can come across in the symmetrical English. So what does Cummings have to add? Well, first of all a new book that will be a pleasant read to many. Secondly, the insights of an expert. Nothing wrong with that. Cummings strives to not only take us through the opening, but also the middle game, which of course is directly linked to the opening, the symmetrical English. The author is successful in this as all 63 games he presents are easy to fol­ low and analyzed from beginning to end. His second wish to cover all critical lines is a bit over­ ambitious given the 'limited' amount of pages he was awarded by Everyman. Cummings' third objective is to reveal all the ins and outs of symmetrical-English move orders. Now, that is quite a task and in itself a reason for many, readers, chess players and writers, to stay away from the (symmetri­ cal) English (or to buy this book as Cummings does not fail). Yet, as it is more about quality than about order in the English Opening, the moves presented by Cummings will be of great help to many chess devotees. The only question that remains is, who will write the 2002

ford. In the meantime he has moved to Australia and now The Ultimate Closed Sicilian has been released by the same publisher. This automatically raises the ques­ tion whether or not this is a rehash of old material. When we compare the Contents we notice the two books use a similar structure, both in terms of variations and of for­ mula (theory incorporated in com­ plete games). Yet my initial doubts proved premature. Lane did write a completely new book, albeit on the same subject. Which players feature in the 64 carefully annotated Main Games? On the White side Adams is a prominent player alongside the 3 S's: Short, Smyslov and Spassky: two English players of the present, two Russian giants of the past. On the Black side Kasparov is the ob­ vious trendsetter, with two games as recent as 200 1 . This is anything but the ultimate book on the Closed Sicilian. Still there can be no doubt that Lane's book gives an excellent insight into all aspects of this opening sys­ tem often used as a strategic alter­ native to the endless tactical jungle of the Open Sicilian. The book is structured around the deployment of both king's knights. White has to decide if he wants it on e2, f3 or

Videotapes Stefan Kindermannn Franzozisch I Franzozisch 11 Winawer

Schach ! ! Verlag - Jtirgen Daniel Price DEM 46.90 each If, after reading Jeroen Bosch 's re­ view above, you decide that Pirc Alert! is not your cup of tea, then here is another complete defence against l .e4: the French, which by the way (according to Stefan Kin­ dermann at least) could equally well have been dubbed the Ger­ man Defence, in view of the large number ofleading German players who have used it on a regular basis, with Wolfgang Uhlmann as their patriarch.

228

These two tapes cover the most important points of a complete French repertoire for Black. Part I deals with The Tarrasch, Ex­ change and Advance Variations and the King's Indian Attack, while the second tape is devoted entirely to the Winawer. It is, of course, impossible to cover all the ins and outs of the entire opening in a little over four hours of taped instruction, but the viewer who follows Kindermann intently through this crash course, will have obtained a nice overview of the opening and will already have a good idea of most of the impor­ tant positional ideas relevant to this repertoire, as well as specific knowledge about the main lines. One will have gathered enough in­ formation to start playing the opening immediately, at least at club level. Of course there are sidelines and subvariations not featured in these tapes which one will want to fill in later. The variations chosen remind one of John Watson's selection in his book Play the French, but there are significant differences. As one would expect from Kindermann, his recommended defence in the 7.'ifg4 Winawer is not 7 . . . 'fl!c7 (as

Watson advocates), but 7 . . . 0-0, the variation on which he wrote an authoritative book together with Ulrich Dirr (see Yearbook 60 for our review). In the Tarrasch Variation both authors offer essentially the same line, Kindermann crediting Wat­ son for some ideas, while criticis­ ing him at other points, e.g. in the line l .e4 e6 2.d4 d5 3 .(Dd2 (Df6 4.e5 (Dfd7 5.�d3 c5 6.c3 (Dc6 7.(De2 'ifb6 8.(Df3 cd4 9.cd4 f6 10.ef6 (Df6 1 1 .0-0 �d6 12.(Dc3 0-0 1 3 .�e3 �d7 14.a3 �e8 1 5.(De5

In this positioin Watson recom­ mends 1 5 . . . �e5 ! 1 6.de5 'ifb2 1 7.ef6 'fl!c3 1 8.fg7 'ifg7. No good, says Kindermann, who considers White's attack after 19.'fl!d2 to be much too dangerous. He offers his own idea 15 . . . J::l.c 8 instead, with some supporting analysis. A peculiar thing happens when Kindermann the introduces Milner-Barry Gambit in the Ad­ vance Variation. He uses the move order l .e4 e6 2.d4 d5 3.e5 c5 4.c3 (Dc6 5.(Df3 �d7 6.�d3 �b6, which is considered inaccurate by theory because of the possibility 7 .dc5 for White. Black should pre­ fer 6 . . . cd4 7.cd4 and only now 7 . . . 'ifb6. In general, however, Kindermann really knows what he is talking about and, in spite of the rather dry presentation, these tapes can be readily recommended to anyone wishing to take up The French De­ fence. Anyone who understands German, that is.

How to read NIC Statistics

Each NIC survey is accompanied by a statistical evaluation of the line or variation under discussion. All statistical data is extracted from the New In Chess Database, containing more than 850,000 games, with aid of the statistical functions incorporated in the NICBASE database software. The New In Chess Database is com­ piled by careful selection of in­ coming data, by sifting out insignificant or obscure games and tournaments as much as possible. The statistics extracted from the database will therefore present a more reliable picture than those gathered from other, maybe larger,

STATISTICS

but more indiscriminitely com­ piled databases. The data is presented as a graph in­ dicating White's scoring percent­ age in four different cases. The number of games upon which the statistical analysis is based is indicated in the white box inside each bar. Each NIC Statistics item centres around the survey position repre­ sented in the diagram at the top of the page. The first bar shows the score over all games featuring this specific position. Generally the other three

bars represent different (sub)varia­ tions or entire opening systems, but in some cases the score of a particular player (an expert in the field) has been depicted instead. For correct interpretation of the in­ formation it is important to re­ member that even if the player defends the Black side of the sys­ tem, the scoring percentage indi­ cated is still that of White. For instance, if the graph shows a score of 40%, this means that the player in question has a success rate of 60% as Black!

1.d4: Best by test! White's score over the entire NIC Database is 54.8%, as can be seen in the graph below. Of White's two main opening moves, l .d4 scores significantly better than l .e4. The main culprit responsible for this state of affairs is portrayed in the fourth bar.
