Preface After the great success of my first two Grandmaster Repertoire books (l.d4 for White), it was not long before the idea of writing about my favourite Black opening, the Griinfeld Defence, was discussed. Ironically this meant searching for an antidote to the line of the Fianchetto Variation on which I had worked so diligently in the second of my l.d4 volumes. My solution to this problem can be found in Chapter 4 of the present book. I would like to share the story of how I became a devotee of this great opening. After I moved to Israel in 1995 my opening repertoire was rather shaky, so during my first few months there I made a serious effort to improve it. Fortunately the Beer-Sheva Club and its manager Ilyahu Levant provided the best possible conditions for such work. My first coach in Israel was Mark Tseitlin, whom I continue to regard as something of a 'Griinfeld guru'. I also received high quality support from Alex Huzman, a strong player who is best known for being the long-term coach of Boris Gelfand. Ever since my first few lessons with Mark, I immediately understood that the Griinfeld was the opening for me. I was attracted by the combative and dynamic positions to which it leads, and relished the prospect of fighting for the initiative with the black pieces. It was especially helpful that all the strong players in my new club knew this opening well. Indeed, in the present work the reader will find plenty of references to the games of Mark Tseitlin, Alex Huzman, Alon Greenfeld, Victor Mikhalevski and Alex Finkel. At that time the influence of the computer was not so strong, and by analysing together we managed to discover a lot of interesting ideas. The Griinfeld has remained my first choice against l.d4 for sixteen years (and counting!), whereas against l.e4 I have changed quite a lot. The Griinfeld is one of the most prominent openings at the highest level, with players such as Shirov, Svidler, Leko and Kamsky using it as their main weapon, while Anand, Carlsen, Topalov and Grischuk also employ it frequently. Let us not forget Garry Kasparov, who made huge contributions to Griinfeld theory from the late eighties until his retirement. The recent Candidates matches paint a remarkable picture. Vladimir Kramnik refused even to allow Alexander Grischuk to play the Griinfeld (which is understandable given that one ofGrischuk's seconds was Peter Svidler), and opened all his white games with l.lLlf3. Gata Kamsky played only the Griinfeld against 1.d4, and his main second Emil Sutovsky is one of the leading Griinfeld experts in the world. Two of Kamsky's clashes with Boris Gelfand in the fashionable 4.ig5 system can be found in Chapter 23. Of course Grischuk lost his vital last game in the final against Gelfand with the Griinfeld, but as we shall see, he did not play the line I recommend! I have always enjoyed the Griinfeld from either side of the board, as the rich positions offer considerable scope for creativity and investigation for both sides. I hope that after reading this book the reader will share my enthusiasm! Boris Avrukh, Beer-Sheva, May 2011

l.d4 ~f6 2.e4 g6 The starting point of our journey into the Griinfeld Defence. Why not start earlier? Sometimes you cannot cover everything; I am sure you will find this book heavy enough as it is. Besides, there should also be room for another book later on ... In this chapter we shall look at A) 3.Wc2, B) 3.d5 and C) 3 •.1gS. Obviously there are many more possible moves, but some of them do not have any point and are not worth studying. And the rest we shall consider in the following chapters. 3.h4!? This outlandish move has been championed by Simon Williams, who recently wrote an SOS article on the subject. 3 ... c5! Black steers the game towards a posltlon where the move h2-h4 is of limited value. 4.d5 b5 4 ... e6!?N also deserves attention, angling for an improved version of a Modern Benoni. 5.e4?! A bit too creative. Williams suggests the improvement 5.h5!?N lDxh5 6.cxb5 a6 7.e4 d6, reaching an unusual kind of Benko position which should be roughly equal. 5... lDxe4 6.h5 YMa5t 7.lDd2 ig7 8.YMf3 lDd6 8... f5!?N is also good. 9.cxb5 ib7 10.hxg6 hxg6 11.~xh8t ixh8 12.a4 a6 13.~a3 This was Vinoth Kumar - Shivananda, New Delhi 2009. White's play has been enterprising but ultimately unsound, and in this position both 13 ... c4N and 13 ...YMb4N give Black some advantage.
Maybe not such a bad idea against the Griinfeld, but the problem is that White gets
a poor version of the King's Indian Defence, where he can have trouble fighting for the vital d4-square. Here is one illustrative example:
3....1g7 Certainly 3 ... d5 4.cxd5 lDxd5 5.e4 lDb6 6.lDf3 is not such a bad version of the AntiGriinfeld for White.

7 ... e58.dxe5 Obviously 8.d5 lDd4 couldn't satisfy White either. 8 ...dxe5 9J~dl c!Lld4 White has lost the battle for the d4-square, and very soon finds herself in a clearly inferior position. IO ..ixd4 10.YMd2 ie6+ IO ...exd4 H.e5 We7 12J~xd4 Wxc5+ Koneru - eAmi, Wijk aan Zee 2006.

5... c66.dxc6
When this chapter was almost ready, I was playing in a rapid tournament and my opponent managed to surprise me with this rare move. But after the game I did some work and came to the conclusion that the most promising response for Black is:
If 6.ltJc3 then Black develops with tempo: 6 ... cxdS 7.ltJxdS \Wast 8.ltJc3 .ig7 9 ..id2 Peev - Radev, Bulgaria 1975. Here simply 9 ...ha6N 1O.ltJf3 0-0 l1.g3 ltJc6 12 ..ig2 l:%fb8 13.l:%bl ltJdS! offers Black tremendous compensation.
6 ... ~xc67.e3
3 ... b5!? Playing in the spirit of the Benko Gambit is logical, since the dark-squared bishop can find a lot of activity on the long diagonal after White has advanced his d-pawn. That said, I believe there is nothing wrong with more classical play, for example: 3 ... c6 4.ltJc3 cxdS S.cxdS d6 6.e4 .ig7 7.ltJf3 0-0 8 ..ie2 ltJbd7 9 ..ie3 ltJcS 1O.ltJd2 e6 With equal chances.
4.cx:b5 a6 5.bxa6 During the aforementioned game I was concerned about S.b6N. However, Black is not forced to take this pawn and can try S... c6 6.\Wb3 .ib7 with interesting play.
Or 7.ltJc3 .ixa6 8.g3 ig7 9..ig2 0-0 10.ltJh3 Varga - Feher, Hungary 1998, and now the naturall0 ... e6N 11.0-0 dS 12.ltJf4ltJg4! would give Black ample compensation for the pawn.
7 ...!i.g7 8.~f3 8.ltJc3 0-0 9.~f3 occurred in Alber Banas, Germany 2000. Black now hurried with 9 ....ixa6, but instead the more accurate 9 ... \WaSN 1O ..id2 .ixa6 would have given him an excellent version of the Benko.
8 ... 0-0 9 ..te2 ha6 10.ha6?! Better is 10.0-0 but after, for example, 10 ... ltJe4 Black still has great compensation.

Quite a tricky move, especially taking into account that it's a rarely seen continuation.
5.f3 %Va5t 6.lDd2 lDxd2 This looks more natural than retreating, as after 6... lDf6 7.d5 d6 8.e4 Black's queen is somewhat misplaced on a5. 7 ..ixd2 %Vb6 8.ic3 .ig7 9.e3 In the event of 9.d5 .ixc3t 1O.bxc3 %Vf6 (also threatening the c4-pawn, by means of 11...%Vh4t) 11.%Vb3 d6, Black has an excellent position. This position arose in Koops - Tesic, e-mail 2005, and now simplest for Black is: 9... lDc6N 1O.lDe2 0-0 Obviously there is no advantage for White.
Cl) 5.d5
3... ~e4 The most challenging reply. Certainly Black can continue with 3 ....ig7, but then he must be ready to play the King's Indian, which is not in our plans, even though White's setup after 4.lDc3 is generally considered quite harmless.
4..tf4 c5 The text is logically connected with Black's previous move and resembles Black's play in a line of the Trompowsky (1.d4 lDf6 2 ..ig5 lDe4 3 ..if4 c5 etc.). Obviously after 4 ....ig7 5.f3 lDf6 6.e4 we would get a strange version of the Samisch King's Indian, with White's .if4 being an extra move.

7.e4d6 We have reached the main crossroads in this line. At this point the most logical moves are Cl) 5.d5 and C2) 5.'1Wc2, but we shall take a quick look at a couple of other moves that White has tried:
8.YlYc2
If 5.lDd2 then the response 5... lDxd2 6.%Vxd2 ig7 is too compliant. After 7.d5 White has a reasonable game, with chances for an
As a consequence of the knight being on d2, White has to take time to defend the b2-pawn, because the natural8.lDgf3 would just lose this pawn to 8... lDh5 followed by 9 ....ixb2.
Finally the game has transposed to a King's Indian type of position, but with White's knight misplaced on d2.

11...e5! Black is probably better already, e.g. 12.dxe6 dxe6 13.0-0-0 e5 14.~g3 ~d7 The idea of ... ~a4 is unpleasant for White.
7 ... tiJf6 8.d5 i.g7 9.i.e5 A natural idea, White's dark-squared bishop is transferred to c3, neutralizing the annoying pin along the el-a5 diagonal. This position occurred in Barsov - Vareille, Val Thorens 1995. I found the following improvement:
9 ... 0-0N 10.tiJh3 e6 Black strikes in the centre, aiming to use his lead in development.
White may be attracted to these rare thirdmove options because they make it problematic (or even impossible) for Black to continue in traditional Griinfeld style. However, by adopting a flexible approach, I believe that Black can obtain good chances. Against 3.Wc2 it is promising for Black to head into a King's Indian in which White's d4-pawn can quickly be targeted. I recommend meeting 3.d5 with the aggressive 3 ... b5!? when Black can expect to obtain compensation typical of the Benko Gambit. Finally 3.~g5 can be met by an idea from the Trompowsky, 3 ... lLle4 followed by 4 ... c5, which assures Black of good play.

White generally chooses between B321) 12.d5 and B322) 12J~~xh5, although there are a couple of less serious options: 12 ..ah6?! has been played twice, but I think it is a blunder, since Black can simply grab the central pawn: 12 ... %Vxd4!N 13.%Vg5 (Black's point is that 13.%Vxd4 runs into 13 ....axh6t-+) 13 ... %Ve5 14.%Vxg7t %Vxg7 15.hg7 Q{xg7 16.lDxe4 .afS 17.~xh5 .axe4 18.fxe4 ~ad8+ White has absolutely no compensation for being a pawn down. 12.g4 This surprising continuation was first employed by Durch Grandmaster Stellwagen in 2008, but we shall follow a later correspondence game, in which White was convincingly punished: 12 ... exf3 13.~xh5 (after 13.gxh5 ig4 14.%vf2 Q{h8 Black is also better) 13 ....axg4 14.~g5 %Vd7 15.d5 f2!

A remarkable position. At first sight it looks as if White has a serious initiative, due to the exposed black king. However, Black's position is like a coiled spring, and in a very short time he manages to develop his pieces and even create significant threats against the white king.
15.hc4 Another line is: 15.~h4 %Vd6! (but not 15 ... lDxb2? 16.~f4! and Black ends up losing the knight on b2, Rodshtein - Sanikidze, Chalkidiki 2003) 16 ..axg7 ~xg7 17.%Vxh5 .ad7! 18.~xe4 %Vb4! 19.~d2 %Vc5 20 ..axc4 (or 20.~d1 lDd6 21.~ed4 lDfS 22.~4d2 lDe3+) 20 ... lDxc4 21.~dd4lDd6 22.~f4 lDfS-+ Black is winning material and he went on to win the game in Aleskerov - Sanikidze, Istanbul 2005. I have to say that Black's play in this game was most impressive; all his moves from 15 ... %Vd6 onwards were simply the best. 15... tLlxc4 16J~d4 White tried 16.lDxe4? in Meessen - Peschlow, Germany 2006, but Black could just grab an important pawn: 16 ... lDxb2!N 17.~d2 (or 17.~d4 c5) 17 ... lDc4 18.~d4lDd6 Black has a winning position. White's best option is 16.ixg7, which has not been played, but is recommended by Ftacnik.
Chapter 2 - 3.f3 A logical c.ontinuation is then: 16.. .!hg7 17.~xh5 exf3 IB.gxf3 (after IB.lDxf3 ig4 Black is clearly better) IB ...~f8 Ftacnik evaluates this position as unclear. It is true that White has a certain amount of compensation following 19.1Dge2 if5 20.lDd4 ig6 21.~h2, but after 21...~f6 I prefer Black's position, due to his strong bishop. It should be noted that White cannot take the pawn back, as after 22.~xc7? lDd6 Black has too many threats (such as ... e5, .. .EkB and ...~f4t).

13.Lf4c5! All Black's pieces are brought into play, even the dark-squared bishop.

This move is the primary subject of the present chapter. 6.~b3 dxc4 7.~xc4 tDa6 would take us to
Chapter 10. 6.e3 cS From this position the most likely outcome is a transposition to one of the main lines considered elsewhere. Let us briefly consider a few independent possibilities. 7.dxcS 7.ie2 cxd4 8.exd4 tDc6 leads to a reversed Tarrasch in which White has the extra tempo icl-f4.

This is not a great idea, as White seems to have forgotten about developing his kingside. 6 ... tDxdS It is worth considering two options here. a) It has long been known that White cannot take the c7-pawn, so I just want to show you why: 7.tDxdS?! ~xdS 8 ..ixc7 tDc6 9.e3 ifS White has tried several moves here, but in all cases the evaluation is clear: Black's superior development is more valuable -than White's extra pawn.

Conclusion Variation A is deservedly rare, and we saw that White's pawn-grabbing expedition is likely to lead to nothing but trouble for him. Variation B with 6.lLlf3 is a bit more respectable, but here too we saw that Black can equalize and fight for the initiative in many lines.

It follows that variation C) with 6.dxc5 Wla5 is the only option that can really threaten the second player, and indeed the next two chapters will be devoted to the critical continuation of 7.!!cl. In the previous pages we saw that none of White's alternatives on the seventh move should be feared. The only one that demands serious attention is variation C3) with 7.Wla4t, but we saw that with the aid of an energetic pawn sacrifice Black can obtain a fine position with the kind of dynamic counterplay which is absolutely typical for the Griinfeld.

Chapter 16 - 7J'kl - Sidelines and 9.lLlge2 A well-known mistake would be 8 ...%Vxc5?, after which - 9.lLlb5 %Vb4t 10.'.!tfl! wins material.
However, after the superior Il.b4!N %Vc6 12.ixe6 %Vxb5 13.ic4 White's bishop pair gives him some advantage.
From this posltlon we will examine two moves in the present chapter: A) 9.a3 and
10.lilge2
B) 9.lilge2. The most frequently played option has been 9.lLlf3, which will form the subject of the next chapter. 9.%Va4 %Vxc5 10.lLlb5 is simply a dubious idea in view of: 1O ... lLld5!

A) 9.a3
In the event ofl0.%Vb3, as played in Almeida Quintana - Bacallao Alonso, Santiago de Cuba 2009, I do not see any problem with 10 ... %Vxc5N. From this position Il.lLlb5?! does not work due to 11...lLld5!=t, and even after the superior 11.%Vb5 %Vxb5 12.ixb5 lLlh5! only Black can be better.

So far five subsequent games have ended in the same way.
Conclusion The 9.lLlf3 system has been White's most popular method of handling the 4 ..tf4 variation. White develops his pieces classically and will usually focus his energy towards the centre, although we have seen over the course of the chapter that the battle might play out across any and all areas of the board. The unusual options of A) lo.lLlbS and B) 1O.'lWb3 should not be ignored, although neither will present much of a threat against a well-prepared opponent. The main line of C) 10..tb3 is more serious, and leads to rich positions in which both sides will face plenty of challenges. The list of variations requiring particularly careful study involves the tricky C2l) 13.lLlgS, the presently fashionable C222) 14.g4!?, the two versions of the thematic exchange sacrifice, C2232) IS.:gxc6 and C22331) 16.:gxc6, and finally the classical C22332) 16J3fdl which can lead to a forced draw. We have reached the end of our investigation into the entire scheme of development starting with the move 4 ..tf4. The theoretical verdict looks perfectly healthy for Black at present, and although some improvements and refinements will inevitably be found for both sides, I am confident that the Griinfeld will continue to prove its soundness.

13.ixe7? ixb2 only leads to trouble for White, and 13.0-0? allows 13 ...'lWd2! winning material. Therefore White has to spend time securing his queens ide before completing development.

Conclusion In this chapter we have dealt with all of White's sensible options after 4.igS lDe4 which do not involve retreating his bishop. The rare options of A) S.lDf3 and B) S.h4 should not cause Black too much concern, although the latter is not a bad move at all. The temporary piece sacrifice C) S.cxdS is tricky, but we saw that Black's bishop pair should stand him in excellent stead. Of the four options examined in the present chapter, variation 0 with S.lDxe4 dxe4 is by far the most significant. The resulting positions with doubled e-pawns are a bit irregular, but we saw that in most lines Black can obtain good counterplay by means of an early ... cS, making full use of the Griinfeld bishop.

This variation has been tested in numerous high-level games.
5... ~xc3 6.bxc3 Ag7 It is important to understand that in the present position Black should avoid 6 ... dxc4?!, as in that case the white bishop will be much more effective on f4 than h4. White has at least two good replies: a) 7.Wa4t Wd7 (or 7 ... c6 8.Wxc4 i.g7 9.lLlf3;!;) 8.Wxc4;!; Compared with the 5..th4 variation Black has no time for ... b6 followed by ...i.a6 as the c7-pawn is hanging. b) White can also play 7.e3 i.e6 8J~bl and once again Black cannot continue in the same way as in the 5.i.h4 variation, as there is no time for the ... lLld7-b6 manoeuvre due to the vulnerable c7-pawn.
7.cxdS WxdS 8.Wb3 (8.d cS transposes to the main line.) So far in all games Black has gone for the queen exchange, but a much more purposeful idea would have been:

White must deal with the attack on the bishop, after which ... lLla5 will eliminate his light-squared bishop. 7.Wa4t i.d7 8.WaS is not dangerous for Black. The simplest solution seems to be:
7.e3 This is the usual continuation, but there are some minor options as well. 7.lLlf3 cS usually transposes to a main line, for instance 8.cxdS (8.e3 transposes immediately) 8...WxdS 9.e3 cxd4 10.cxd4 lLlc6 11.i.e2 0-0 and we have reached the main position after move II in variation C below.

23 .. J:i:e8 From here I do not see anything better for White than regaining his pawn:
24..b:b7 ~xb7 25J;xb7 It is hard to see this opposite-coloured bishop endgame finishing in anything other than a draw.
The system beginning with 5.J.f4 is a sensible try which has been tested in numerous highlevel games. Following the usual sequence of 5 ... liJxc3 6.bxc3 ig7 7.e3 c5 8.liJf3 0-0, we investigated three main moves. Attempting to save time with either A) 9.gbl or B) 9.'Wb3 leads nowhere for White, so the main line of C) 9.cxd5 cxd4 10.cxd4 'Wxd5 Il.ie2 liJc6 12.0-0 is critical. Then after l2 ...if5 13.'Wa4 'Wa5 both Cl) 14.'Wxa5 andC2) 14.'Wb3Iead to roughly similar situations without queens. The latter is considered slightly more challenging, but according to the above analysis Black should experience no particular problems. In all these lines his position remains fundamentally sound, with considerable dynamic potential, as illustrated by lines such as the note to White's 16th move in line C2.

B) 7.~a4t is more significant, especially as Black must keep in mind the possibility of a transposition to Chapter 25. Fortunately we saw that, in the cases where White attempts to derive independent value from the early queen check, Black has at least enough resources to maintain the. balance, and quite possibly fight for the advantage.

A} B.ltlh3 is not completely without merit, but analysis shows that Black can obtain an excellent game with resolute play. B} B.ie2 is not such a bad move, and usually transposes to a line examined in a different chapter. As we have seen, Black has nothing to fear from the independent possibilities.

9....t.d5 9 ...J.g7?! would be a serious concession, as after 1O.J.xc4 J.xc4 11.Wfxc4 White has regained the pawn while keeping a safe positional edge. After the text move Black is threatening to consolidate his extra pawn with ... a6 followed by ... b5, so White is more or less forced to take the following path:
After a more or less forced sequence of moves, we have reached the position for which White has been aiming. Despite having only two minor pieces for the queen, he has reasonable compensation thanks to his superior coordination and safer king. Nevertheless I do not believe that Black should have any serious problems, and I was happy to defend my point of view at the 2.008 Dresden Olympiad, in a remarkable game against Tiger Hillarp Persson, which we will now follow.

The queen sacrifice associated with B) 9.Wla4 is fascinating, but as long as Black keeps a cool head and finds the right moves at a few key moments, he should be able to count on at least equal chances. Line C with 9.lLlf3 sees White developing more calmly, but after 9 ... lLl b6 Black secures his extra pawn and keeps enough dynamic potential to fight for the initiative, perhaps with a material sacrifice of his own.

Conclusion Simply developing with A) 9.~e2 is a sensible option; Black must play accurately, but if he does so then he can count on securing equal chances. Attacking the b7-pawn with B) 9.'lMfbl is well met by 9 ... 'lMfd5. White will regain the c4-pawn, but the queens are liable to come off, resulting in a level endgame. The other method of attacking the b7-pawn is 9.l"Ibl, which can lead to very interesting tactical play; in particular, C31) 9 ... b6 1O.~e2 0-0 11.tt:ld2 c5! 12.~f3 cxd4! is a highly promising rook sacrifice.

This variation is clearly similar to the line with 4.'1Wa4t that we examined in Chapter 9. Indeed the two most popular moves here, S.~f4 and S.e4, transpose directly into that chapter, to lines A and B 1 respectively. There remains one other reasonable move to look at: 8.g3 i.e6 Chasing the white queen away should help Black to get in the desirable ... c5, although

I have never faced this move in practice, but in my database I found over 600 games where it has been played. 5 ... dxc46.\Wa4t The alternative is: 6.ig2 c6! It is already not so easy for White to regain the pawn. The arising position slightly resembles some Catalan lines where White plays for compensation for the pawn, but I believe that Black's dark-squared bishop makes a big difference here - from g7 it has a lot of influence on the centre. 7. tt'l e5 7.0-0 0-0 and 7.a4 0-0 8.0-0 transpose to lines C and C2 respectively of Chapter 5. 7 ... tt'lg4!

13... eSN 10.d5 This pawn sacrifice doesn't work here: 10 ... ixc3t 11.bxc3 ~xd5 12.0-0 ie6 White had no compensation for the pawn in Niebaum - Krueger, Essen 2006. 10.0-0 tLlxd4 11.tLlxd4 ~xd4 12.E1d1 (after 12.tLlb5 Docekal - Dvorak, Znojmo 2002, Black should play 12 ... ~c5!N 13.ie3 ~c4 and White does not have enough compensation for the pawn) 12 ...~g4 13.if3 Schwartzman Martinovsky, Saint John 1988.

After A) S.e3 Black can keep the pawn with S... b5, when it is not clear that White can obtain enough compensation. Therefore it is safer for White to regain the pawn immediately with B) S.~a4t.

Conclusion Of White's eighth move options, A) 8.Wa4t is not too threatening. Black should equalize easily, although the resulting positions can be very drawish; perhaps 18 ...id7!?N in the main line can keep some life in the game. After 8.Wd2 h6 9.tLlh3 exd5 10.We3t 'it>f8 Il.tLlf4 the displacement of the black king should not be too worrying. With B22I) 11...c6 Black aims to unravel slowly, but his long-term prospects seem good; however if that is not to your taste then B222) 11...c5 offers a more direct route to equal chances.

Conclusion
15.i.d2 Other possibilities are: 15.i.xd3 lLlxd3 16.Wc2 lLlb4 17.We4 Wd5 18.Wh4 (this looks logical, but it is better to allow the queen swap with 18.a3 Wxe4 19.1Llxe4 lLl4d5 with approximately equality) 18 .. .f6! This strong move greatly restricts White's play on the kingside. 19.~h6 This was Gershon - Ma.

Black will continue with ... lLl6d5 and he seems to keep everything under control. 15.Wc1 ~xe2 16.lLlxe2 This occurred in Volke - Brendel, Dresden 2007, and here I developed the following regrouping for Black: 16 ...

After 7 ... lLlc6 White has a wide range of alternatives to the usual 8.~e2, but none of these moves promise him any advantage. Perhaps the rwo most tricky lines are variation B) 8.~f4, which we meet with a spectacular line, leading to an advantage for Black, and variation £) 8.h3, when instead of the usual 8 ... lLld7, the blunt 8 ... e5! solves all problems.

17.tLldl e6 IS.dxe6 fxe6 19J~cl 'iNb6 20.b4 tLlb7 21.bxc5 tLldxc5 22.'iNb4 'iNd6 23.tL\c3 .ie5 24.g3 tLld7 25.'iNxd6 tL\xd6 26J3fdl tLlf6 27.f4 i.xc3 2SJ~xd6 tLlxe4 29J3xa6 .id4!
Maybe White could try 15.tLlb5 tLlxc6 16.Wi'a4, although Black has no problems and can respond 16 ... tLle5 with some attacking ideas.
15 ... bxc3 16.exf6 Lf6 17.bxc3 tLlxc6 IS.i.h6.ig7 19.i.xg7 ~xg7 Although the position looks fairly equal, there is some strategical danger for White due to his weak c-pawn. In Vallejo - Roiz, Dresden (01) 2008, White had to suffer for a while before eventually securing the draw.

The idea of exchanging White's darksquared bishop appears very logical to me. Instead IS ...

Chasing the black knight away with B) 9.d5 is a more challenging approach, but in return White loses time with his queen, and with careful play Black can be confident of equalizing. However White must also play with care; as I point out in the notes to line B 11, the pawn sacrifice with 14 ... tLld7 and 15 ... c5 can be dangerous in certain circumstances. Finally in line B234 I refer to a game in which I suffered, but that was because I chose the wrong square for my queen; with 16 ... 'Wc7!N Black can solve all his problems.

New Opening Books
This book is part of a new series from Quality Chess examining the cutting edge of opening theory. The idea is to identify the most important theoretical battlegrounds and then analyse as deeply as possible in search of improvements. Thus the reader will be ahead of the current state-of-the-art, rather than lagging behind trying to memorize old games. The Cutting Edge 2 considers the Sicilian Najdorf - a favourite opening of ambitious players at every level. This book concentrates on lines where White chooses 6 ..ie3, heading for the English Attack.
After one move of the Scandinavian opening, 1.e4 d5, Black decides where the battle will be fought - a significant gain for any competitive player. Grandmaster Christian Bauer is one of the world's leading experts on the Scandinavian and in this book he reveals the secrets of his over-the-board success. Bauer focuses particularly on 2.exd5 'Wxd5 3. tiJ c3 'Wa5, the established main line of the Scandinavian. An understanding of the move order nuances is essential, and Bauer is an ideally-qualified guide.
The Sicilian Defence, 1.e4 c5, is one of the popular chess openings. In this book several grandmasters present stateof-the-art analysis of lines where White meets the Sicilian by avoiding the Open variations. The editors, 2007 British Champion GM Jacob Aagaard and three-time Scottish Champion GM John Shaw, have recruited a line-up of strong chess grandmasters to share their expert opinions both on how to play the Sicilian Defence and how to play against it.
Grandmaster Repertoire An update to a Classic Concept
Creating the Grandmaster Repertoire series seemed a natural idea. There has been a glut of opening books offering simplistic coverage of a subject. Apart from a few exceptions, it almost seemed like the concept of a high-level repertoire book had been forgotten. As chess players and fans, we felt we were missing out, and because we can, we decided to do something about it. The books in the Grandmaster Repertoire series are written by grandmasters, edited by grandmasters, and will certainly be read by grandmasters. Of course, this does not mean that players who are not grandmasters cannot benefit from them. We have worked hard to make our books clear in their presentation and to make it possible for the readers to decide the depth to which they want to study them. It is our conviction that most players will eventually enjoy greater success by playing the main lines, simply because they are, in most cases, based on stronger moves. Instinctively most players know this, but for one reason or another they employ easy-to-Iearn but unambitious systems, or dubious gambits. These approaches may yield success from time to time, but we would argue that they are less conducive to a player's overall development. In these days of multi-million game databases, we all have access to information. The difficulty comes from trying to navigate through the ever-expanding jungle of games and variations. In this groundbreaking new series, readers will be guided by the insights of grandmasters, each chosen for their special expertise in the opening in question. We are immensely excited about this new series, and we hope that the readers will share our enthusiasm.
