Of all the possible replies to 1 .e4, the Scandinavian is the only reputable option which creates an immediate pawn clash in the centre. This means that it differs from most other openings where a variety of pawn structures can be reached. For example, the French Defence is noted for thematic positions with a rigid pawn chain (where the white phalanx d4-e5 is blocked by Black's d5-e6) but many other structures can also be reached. In contrast, in the Scandinavian, right from the start Black breaks up the pawn structure. We will see that 2.exd5 constitutes White's only worthy reply, so players using the Scandinavian can be sure of reaching their favourite scheme. This point should be underlined, since it is a unique case among 1 .e4 openings. The Scandinavian highlights the activity of the pieces and this factor is predominant in the first phase. Indeed, the usual pawn structure - d4 for White vs. the black duo of e6 and c6 - is unlikely to evolve in the near future. As we will see throughout this work, the assessment of the position greatly depends on the circumstances in which the d4-d5 push may be achieved. Black is often slightly behind in development, a consequence of the queen's early outing, and he must therefore be especially cautious about this central thrust, as it would open the game in favour of the white forces. The main drawback of the Scandinavian, these lost tempos by the queen which lead to Black being behind in development, is the reason why some claim this opening is dubious. It is true

Play the Scandinavian

that Black disobeys two major chess principles: he commits his queen early (2 . . . Wfxd5) and then he moves the same piece again (3 . . . Wfa5). Despite these sins, the Scandinavian should not be dismissed, as Black acquires numerous advantages from the main line introduced by 3 . . . Wfa5 . In essence, Black hankers after an improved Classical Caro-Kann ( 1 .e4 c6 2.d4 d5 3.liJc3 dxe4 4.liJxe4 ifS) while having avoided various White divergences on move three, notably the critical Advance Variation and the Panov Attack. If Black succeeds in developing his light-squared bishop and then completes his development without harm, he will have a perfectly sound position, without any 'bad' pieces. Another element that one should mention in favour of the Scandinavian compared to the Caro Kann, in addition to avoiding the need to study sharp theoretical systems such as the Advance Variation, concerns the white c-pawn. If White chases the enemy queen from the centre with 3.liJc3, then the c-pawn is blocked on its original square. In consequence, White has less potential activity than in the main line of the Caro-Kann, and so it is difficult to profit from any extra tempos. In this book, after l .e4 d5 2.exd5 Wfxd5 3.liJc3, I shall analyse only 3 . . . Wfa5 and not 3 . . . Wfd6 or any of the sidelines such as 3 . . . Wfd8 or 3 . . . Wfe5t. The latter two moves are certainly inferior, but the reader may wonder why I have studied 3 . . . Wfa5 and not 3 . . . Wfd6, which is also popular. There is no consensus on the respective value of these two queen moves. For example, Nigel Short seems convinced that 3 . . . Wfa5 is inferior due to his system (4.i.c4 and next 5 .d3) , while Eric Prie swears by 3 . . . Wfa 5 . As for me, I am certain that these two moves have roughly equal merit. As 3 . . . Wfd6 appeared more recently at grandmaster level, the theory of this variation is less developed. This has pros and cons: a greater chance of innovations but also more difficulties learning what each side should avoid. Regardless, there is plenty of interesting material to consider with 3 . . . Wfa5 without adding more about other moves. The Scandinavian has served me well for many years. I hope the reader is equally fortunate. Christian Bauer Montpellier, France, September 20 1 0

the major argument lies in the solidity of his formation. Without further delay, let's see how the game may develop after the first of the aforementioned knight hops.

In this, the first chapter of the book, we are jumping straight in at the deep end and analysing the variation that is most likely to appear on a Scandinavian player's board nowadays. a

In the above pOSItiOn White normally chooses between the related, yet quite distinct continuations of A) 8.llJe4 and B) 8.llJd5, which will be analysed in turn. The other main option is B .\We2, which will form the subject of Chapter 2, while the remaining alternatives will be covered in Chapter 3.

By choosing this square Black is visibly hoping for 9.llJxf6t, which would transpose into line B with B .llJd5 \WdB . Unfortunately for Black, the queen is less than ideally placed on its original post, which enables White to profit from avoiding the transposition.

Why is the idea of exchanging knights so popular for White? For one thing, the c3knight is traditionally a poor piece in the Scandinavian, so it is logical to take the opportunity to exchange it for the more active one on f6. Furthermore, after the subsequent llJxf6t Black will have to make a difficult decision: either he compromises his pawn structure or allows his queen to be drawn out into an exposed position. In general terms, White's position is sound and relatively easy to handle, at least for the next few moves. From Black's point of view

9.llJg3! Ag6 Safer is: 9 . . . Ag4 The bishop will have to exchange itself for the knight on f3 in the near future, but Black's position will remain solid and only a little worse. 1 0.c3 llJbd7 1 O . . . llJh5?! 1 1 .\Wb3 llJxg3 1 2.hxg3 Axf3 was tried in Golod - Sergeev, Hlohovec 1 994. Here White's strongest reply would have been 1 3.gxf3!N (The game continuation of 1 3.\Wxb7 Axg2 1 4 .:!:!h2 llJd7 1 5 .:!:!xg2 was

We have reached a position resembling those that may arise from the Caro-Kann, as well as the "Fort Knox" variation of the French Defence ( l .e4 e6 2.d4 dS 3.ltJc3 dxe4 4.ltJxe4 i.d7, intending . . . i.c6) . The bishop pair confers on White a slight but risk free advantage, although at the same time the black fortifications are hard to shake. (There is a reason why the aforementioned variation of the French Defence received that particular moniker. . . ) 1 3.ltJe2 Wc7 1 4.g4 White is not forced to act so energetically, and he may have been better off playing more patiently with 1 3.0-0 0-0 1 4.�fe l . 1 4 . . . ltJdS Another game continued 14 ... 0-0 I S .gS ltJdS 1 6.0-0-0 bS 1 7.i.d3 cS 1 8 .mb l c4 1 9.i.e4 ltJ7b6 20.h4 �aeB 2 1 .�dg l b4 with decent counterplay for Black, Bologan lonov, Kazan 1 99 5 .

Obviously there is a lot of play in the position, but presumably White offered a draw on the basis that he lacked any real advantage.

lO.h4! This aggressive move highlights the drawback of Black's decision to retreat his bishop rather than exchange it. Instead the timid 1 0.c3?! would be good enough for equality after 1 O . . . ltJbd7. lO ... ltJh5!? This creative solution is unfortunately insufficient to solve Black's problems, although his position is already quite dangerous. He should certainly avoid: l O . . . hS? 1 1 .ltJeS i.h7 1 2.We2± 10 . . . i.d6!? This rare move may be the least of the evils. 1 1 .hS i.e4 ( l 1 . .. Lg3?? 1 2.hxg6 i.c7 1 3.gxf7t+-) 1 2.ltJxe4 ( l 2.h6!?N) 1 2 . . . ltJxe4 1 3 .i.e3 ( l 3.h6!?N) White maintained an edge in Zeleic - Fierro Baquero, Cannes 2007, but at least Black's position is not about to collapse any time soon. Black's most common reply has been: 1 O . . . h6 But this has not brought him much success. 1 1 .ltJeS i.h7 1 1 . .. Wxd4? 1 2.ltJxg6 fxg6 1 3 .We2± 1 2.We2 We have reached the same position as in the game Nedev - Slovineanu (see variation A

in Chapter 8) except that the white knight is on eS rather than f4, turning an already promising position into an even better one. 12 . . . ltJdS 12 . . . J.d6?? loses trivially after: 1 3.ltJxf7 mxf7 14.'!Wxe6t mg6 I S .hS# 13.0-0-0 13 .WhS!?N also looks dangerous. 13 . . . ltJd7 14.f4 ltJxeS Relatively best. 14 . . . J.e7?! I S .ltJhS 0-0 1 6.Wg4 g6 17.ltJg3 is clearly unappetizing for Black. I S .fxeS I S .dxeS?! would spoil a good part of White's advantage. I S . . . Wc7 16J::ihfl 0-0-0 1 7.5 Arakhamia - Olbrich, Yerevan (01) 1 996. Now Black could have got out of the woods with 17 . . . mb8!N (instead the game continuation of 17 . . .J.xfS 18 .ltJx5 ex5 19.!!xfS g6 20.!!f3 J.g7 2 1 .e6! yielded White a big plus) 18.Wg4 J.cS with a decent game. I S . . . Wc7 1 6.!!hfl 0-0-0 1 7.!!f3 bS This radical measure weakens the black queenside, but also secures the position of the knight on dS. The alternative was 17 . . . @b8 18.!!dfl !!d7 followed by passive defence. 1 8.J.d3

Black decided here to throw in the towel in view of the impending J.bS . It was perhaps a bit early to resign, but in any case the whole game provided a useful illustration of the kind of trouble Black must strive to avoid.

H .We21 White does best to ignore the cheeky knight, as the exchange on g3 can bring him certain benefits.

H ltJd7 The immediate exchange on g3 would have increased White's options: 11 . . . ltJxg3?! 12.fxg3 ltJd7 (12 . . . J.xc2? loses fast: 13.ltJgS!

9 . gxf6 Black is effectively a tempo up on variation B2 (8.tLld5 Wfd8 9.lLlxf6t gxf6) , although it is not the type of position in which a single move should make a massive difference to the overall evaluation. I suppose the present line may appeal to White players who are happy in the type of positions resulting in the . . . gxf6 pawn structure, but are, for whatever reason, reluctant to enter variation B1 with 8.lLld5 Wfd8 9.lLlxf6t Wfxf6. ..

15 . . . 0-0-0! ?N A few games have continued with 15 . . . h5 16.0-0-0 if5 17.Wfe3, but the resulting po sition is problematic for Black, for instance: 17 . . . 0-0-0 (17 .. J!:g8 was suggested as an improvement by Wahls, but the remedy is worse than the disease, since after 18.ixd6 Wfxd6 19.d5!, intending to meet 19 . . . Wfb4 with 20.E:d4, Black is in trouble.) 18 .ixg7 ixg3 19.E:dfl E:hg8 20.if6 Black failed to equalize and eventually succumbed to the pressure along the e- and f-files in Glek Wahls, Bundesliga 1996. 16.h5 16.0-0-0?! ixe5 17.dxe5 h5 is at least equal for Black.

l O.Wfe2 It is worth mentioning that the slow l O.c3, despite having been played by such esteemed players as Psakhis and Bologan, is a slight inaccuracy. The point is that after l O.Wfe2 the c2-pawn is poisoned, as we will see in the note to Black's next move in the main line below.

Chapter 1 - Main line 8 .lLle4 & 8 .lLld5 1 0.0-0 should not worry Black. 1 O . . . llJd7 I I .lLlh4 Compared with the analogous position arising in variation A3 below, the position of the queen on c7 instead of b6 will help Black in a position with mutual attacks.

This accurate move brought White a distinct advantage in Nunn - Conquest, Hastings 1996. White is no longer interested in exchanging what is now a misplaced bishop on g6, and instead wastes no time in preventing . . . f4, which would have liberated that piece. Finally it is worth noting that Black is in no position to exploit the e4-square, which can always be covered by f2-f3. I would advise the reader to remember the following rule of thumb: the move .. .f6-f5 is usually an effective reaction against a pawn on f4, but should usually not be played in situations where White is able to prevent the further advance of this pawn using pieces, as was the case here. Going back, the other main option on move 13 is: 13 . . . lDb6!? 14.Wff3 .ie7 14 . . . .ig7?! 1 5 ..if4 Wfd7 16.!!he l lDd5 17.J.g3 is unpleasant for Black, who will have to face the plan of c4 and later d5 , which can perhaps be preceded by lDxg6 and/or f1 with promising compensation. 1 0.0-0! ? This sets a clever trap: 1O . . . .ixf3?! Instead Black should choose between the natural and solid 1 0 . . . lLlbd7 and the more daring 1 0 . . . Wxb2, intending to meet 1 1 .�b 1 with 1 1 . . . .ixf3.) 1 1 .Wxf3 Wxd4?! Consistent, but bad. 1 2.Wb3 Wb6 1 3 . .ixe6! Black can hardly accept this gift, and he is therefore in trouble. 1 0 . . . a5 Black can also consider the slightly cheeky pawn grab: 1 0 . . . .ixf3!? 1 1 .Wxf3 Wxd4 1 2.0-0-0 lLlbd7 Mueller evaluates this position as unclear, and I agree, as White is unable to exploit the seemingly exposed black queen, while his opponent is ready to castle soon and may obstruct the d-file by . . . lLld5.

This very position is commonly reached in line B252 (beginning on page 52) except that here the black queen is on b6 instead of c7 and the white bishop is on c4 instead of b3.

In this position Black faces a major decision. If he is willing to take a risk in order to unbalance the game, he can consider grabbing the b2-pawn. The safer option involves the straightforward completion of development, although it should be emphasized that the resulting position with opposite-sided castling will still lead to very lively play. Ultimately I think both approaches are equally valid, and the choice will depend on one's personal taste and tournament/match tactics.

lO...Wxb2!? I decided to give this as the main line, mainly because the resulting complications were so interesting to analyse. Here are a couple of instructive examples involving the other plan. 10 . . . lLld? 11.b4 �d6 12.E:e l E:g8 13.\t>h l Perhaps White would have been better off doing without this move in an effort to save time. 13 . . . 0-0-0 14.�fl This retreat is a logical choice, guarding the g2-pawn and making way for the c-pawn to advance.

Despite the queen exchange, White's activity compensates for his pawn deficit and Black should take care over his next few moves. I believe he can defuse his opponent's initiative and obtain equal chances provided he avoids the tripwires on the path.

In this position I found a new idea:

The text move is directed against that very idea, as we will soon see:

lS.ixe6? White should instead opt for a quieter move, in which case he will have adequate compensation for the missing pawn, but no advantage. lS ... fxe6 16.gxe6t ie7 17.ib4 O-O-O! And Black wins. A32) lo.ib3

As mentioned previously, this move theoretically maintains the possibility of castling on either wing. However, in practice the white king is more likely to castle on the queenside. The problem with short castling is that after Black castles on the opposite flank, the game will enter a phase of mutual attacks. The bishop on b3 will not be able to contribute much for either attacking or defensive purposes, and only serves to obstruct the b-pawn. We will see a good example of this in the game Schmidt Schaeffer - Vidoniak, in the note to White's 12th move below.

lO aS! I prefer this over 10 . . . lDd7 I l .Wle2 ig4?! (This is inaccurate, as it will be too risky for Black to grab the d4-pawn.

Chapter 1 - Main line 8 . ttJ e4 & 8 . ttJ d 5 The knight is heading for b4 and perhaps later d5. If White plays c2-c3 at some point, in order to expel the knight from b4 and/or bolster his d4-pawn, the bishop on b3 will become unstable. These factors, combined with the half open d- and g-files, make Black prospects quite interesting in my view. Let's examine some practical examples to illustrate this assertion.

20 ... £5 Prie thought afterwards that 20 . . . gS!?N was stronger, as White will not be able to swap bishops. However, I am not convinced that Black can claim an edge after 2 1 .dS! (2 1 .Wxf6? g4 22 . .if4 Wd7 is perilous for White) 2 1 . . .fS 22.dxc6 bxc6 (or 22 . . . Wxc6 23.Wxc6t bxc6 24 . .id4 g8h7 2S . .ib6) 23 . .id4 g4 24.We2 g8h7 2S . .ieS . It is true that Black will manage to play . . . gxh3 soon, but after the reply g2-g3 this will not have brought him much. 21..if4 .id6 22.h:d6 Wxd6 23.d5! White just manages to create counterplay before his opponent's kingside attack gathers any real momentum. 23 ... exd5 23 . . . gS!?N would have given better practical chances to press for a win, although on the flip side Black would also have to find some accurate moves after: 24.Wc3! (24.dxc6 Wxc6 and 24.dxe6 g4 2S .Wg3 We7 26.gad l fxe6 are both a bit better for Black.) 24 . . . g4 2S .cS! Wd7!? (and not 2S ... WxdS?? 26.gfd l We4 27.gd4 We2 28.gad l when White's attack arrives first) 26.d6 f4!? Now a logical continuation would be: 27.Wxa5 Wxd6 28.cxd6 gxaS 29.hxg4 �d7 Black has a tiny advantage in the endgame, but realistically a draw is by far the most likely outcome.

9.lOxf6t Now Black is confronted with the dilemma of how to recapture, so we will consider both BI) 9 Wxf6 and B2) 9 gxf6 in turn. The current status of theory is tipping the scales in favour of the latter, although I would still invite the reader to examine both paths and form his own conclusions. •••

alternatives. In the present posltlon Black has three main moves: Bl l) 10 .id6, B12) lo ..lLld7 and B13) 10 .ig4 . The latter two will often transpose, although independent possibilities do exist.

It should also be mentioned that l 1 .lLleS?! gets nowhere after: 1 1 . . .lLld7! 1 2.lLlxd7 g;;x d7 1 3.0-0-0 �ad8 White is obviously unable to break through with d4-dS , and the position is just equal.

1 O . . . .ixc2?! is too risky and is only rarely seen. White has a generous selection of promising moves, including 1 1 .0-0, 1 1 ..ic3 or even l 1 .dS. In every case, at the very least White obtains excellent compensation. First, let's consider what happens if White castles:

The most significant alternative is: 1 1 .0-0-0 O-O! This fresh try seems to give Black better prospects than the alternatives. One such example is: 1 1 . . .'We7?! 1 2.lLleS! Intending g4, with a powerful initiative. 1 1 . . . .ig4?! is strongly met by 1 2.dS!, after which the d6-bishop will soon become uncomfortable. For instance: 1 2 . . . .ix8 ( 1 2 . . . cxdS 1 3 . .ixdS lLlc6 14 ..ic3 'We7 I S . .ixc6t bxc6 1 6 . .ixg7± Neukirch Cording, Dresden 2003; 1 2 . . . eS 1 3 .h3 [ 1 3.'Wd3!?1 1 3 . . . .ixf3 1 4.gxf3 cxdS I S . .ixdS lLlc6 1 6.�hg l And the black monarch has no safe haven.) 1 3.gxf3 cxdS 1 4 . .ixdS lLlc6 I S . .ic3 'Wf4t? (This unfortunate decision and the next one accelerate the fall, but Black was in serious trouble anyway. For instance, I S . . . .if4t 1 6.G;; b l eS I 7 . .ixc6t bxc6 1 8 . .ib4! With his king stuck in the centre Black will not survive for long.) 1 6.G;; b l 0-0 1 7.hc6 bxc6 1 8.�d4 'WeS 1 9 .'Wd3 1 -0 Movsziszian - Prie, Marseille 200S. 1 2.lLleS bS 1 3 . .ib3 as 1 4.a3 This position was reached in Azarov - Rep kova, Warsaw (rapid) 2009, and here Black could have obtained a decent position with:

..•

1 1 .0-0 .id6 Little better is 1 1 . . . lLld7 1 2.dS cxdS 1 3 . .ibS . For example, 1 3 . . . a6 1 4 . .ic3 and White wins a piece. 1 2.dS cxdS 1 3 . .ixdS lLlc6? This gets blasted, but the alternatives also lead to trouble. For example, 1 3 . . . lLld7 1 4 . .ixb7 �b8 1 S ..ic6 and Black's minor pieces are all in trouble. Or 1 3 . . . 'We7 when one of White's many options is: 1 4 . .igS 'Wd7 I S . .ixe6 'Wxe6 1 6.'Wxc2 0-0 1 7.�fe l 'Wg6 1 8 .'Wxg6 hxg6 1 9 . .ie7 .ixe7 20.�xe7 With a strong grip in a simple ending. 14 . .ixc6t bxc6 I S .'Wc4 'Wxb2 Now in Jonkman - De Vreugt, Tel Aviv 2000, White could have won a piece with: 1 6.'Wxc6t g;; e7 1 7 . .ic 1 ! The first player may also consider the rather forcing line l 1 .dS! ? cxdS 1 2 . .ibS t lLlc6 1 3 . .ic3 'Wg6 1 4.lLld4 'Wxg2 I S .g;; d2, which may well prove very good for him.

Bl l) 10 .id6 1 1 .ig5!? ...

This unusual move may well be White's most convincing route to an advantage. The premature I I .dS?! squanders White's initiative after 1 1 . . .cxdS 1 2 . .ixdS 0-0 1 3 . .ic3 'We7, with a balanced game.

It should be noted briefly that 2 1 . . .e5? only leads to an increase in Black's worries after 22.t.xc5 t.xc5 23.b4! with a marked edge to White, for instance: 23 . . .t.fS 24.'lWe6t 'lWd7 (24 .. .'itj'bS? 25 .1"1:d l +-) 25 .t.xb7t etc.

24 g6!? 25.¥Mxf6 E:d8 Black will likely recover a pawn on either f2 or h2. White can play for a win without any risk, but the presence of opposite-coloured bishops is a significant drawing factor.

We have arrived at an important crossroads, from which we will analyse five main moves: B2 1) 10.Af4, B22) 10.0-0, B23) 10.¥Me2!?, B24) 10.c3 and finally the main line of B25) 10.Ab3.

•••

When opting for the recapture 9 . . . ¥Mxf6 Black leaves himself almost no opportunity to deviate from the main theoretical path. He thus condemns himself to a defensive role, with limited prospects of playing for more than a draw. That being said, there is scope for the second player to prepare in considerable detail, and with precise play Black has decent chances to neutralize his opponent's edge in the critical lines.

This will not only affect his chances in the endgame, but will also render short castling problematic. On the other hand the half-open g-file is a valuable source of counterplay, and Black also avoids moving his queen into an exposed position. Moreover, there is usually no harm for Black in castling long, and his

This position was reached in Kais - Brandys, Oberschwaben 1 995 (via the Caro-Kann move order noted previously) . Here the following untested approach looks quite interesting:

With this move White obtains a better version of one of the S.liJe4 lines: compare both 1 0.0-0 in the note to White's 1 0th move in line A2 (after S .liJe4 Wlc7 9.liJxf6t gxf6) , as well as variation A3 1 (S.liJe4 Wlb6 9.liJxf6t gxf6 1 0.0-0) . In the present position there is no denying that the black queen is worse on dS than it was on either c7 or b6 respectively, and Black will almost certainly have to spend a tempo on . . . Wlc7 (or . . . Wld6) in order to facilitate queenside castling. That being said, the second player is still not doing badly and the open g-file will offer plenty of counterattacking chances.

Compared with the other big main line of B2S with 1 O . .tb3, this move has the advantage of reinforcing the d4-pawn, thus enabling the

a good idea.

pawns are not such a big handicap, and Black may even benefit by utilizing the eS-square for his pieces. The position will be difficult to win for either side.

Conclusion In this chapter we have examined the numerous methods at Black's disposal to counter 8.lLle4 and 8.lLldS. Clearly he should avoid 8.lLle4 %Vd8 ?! because of 9.lLlg3, when White obtains an edge. On the other hand, the retreats to b6 and c7 both seem fully satisfactory. After the more frequent 8.lLldS %Vd8 9.lLlxf6t, variation B l with 9 . . . %Vxf6 has been under a cloud ever since the game Sanduleac - Prie, which has led to line B2 with 9 . . . gxf6 becoming recognized as the main line. Although Black may fall marginally short of full equality here, his position remains safe and solid, and the ball is in White's court to demonstrate a tangible advantage.

8 ... .ib4 This standard response introduces a central theme in the Scandinavian, namely the issue of how Black should conduct the position without his dark-squared bishop after a2-a3. From our starting position, the immediate 9.a3 is White's most accurate move, as by comparison with 9.0-0-0, White effectively rules out the option of 9 . . . ttJd5. If he intends to castle short then the move order is not so important, but that whole strategy is too timid to threaten the opponent.

10 hc3 1 l .hc3 VfJc7 Practice has shown that White will have a hard time making his bishop pair count for anything in this position. Black's formation is rock-solid, and he can look to develop active play on the light squares.

doubled pawns are not a real handicap, and Black has the b- and c-files for his rooks. He is thus a bit more active, but the presence of opposite-coloured bishops leaves little chances to press seriously.

This is arguably White's most accurate choice, as by comparison with 9.0-0-0, White effectively rules out the option of 9 . . . lDd5 for reasons that will soon become apparent.

9 ... lDbd7 9 . . . lDd5? can effectively be refuted as follows:

This position was reached in Schmittdiel Reefschlaeger, Binz 1 994. White stands clearly better. The presence of doubled c-pawns is no nuisance at all because Black cannot anchor his centralized knight. White's plan for the next few moves will be to retreat his bishop from c4, defend its brother on d2 and then play c4. If Black tries to stabilize his knight with

. . . b5 then White can either play c4 and repeat the process, or perhaps even consider the alternative undermining plan of a4, depending on circumstances.

10.0-0-0 1 0.0-0 will soon lead back into line B. The text move is much more challenging, and leads us into what has historically been one of the most important battlegrounds in the Scandinavian. It was tested extensively during the 1 990s, and was especially prevalent in the German Bundesliga. This is largely due to the influence of the German grandmaster Matthias Wahls, who employed the Scandinavian with considerable success during that period.

10 ...hc3 1 0 . . . i.xa3? is plainly wrong: 1 1 .lLld5!?N (The one elementary trick that White must avoid is 1 1 .bxa3 Wfxa3t 1 2.@b 1 Wfb4t 1 3 .i.b3?? Wfxb3t! Blaas - Knijft, Haarlem 1 997.

This may not be 1 00% sound, but it leads to heavy complications and might appeal to players who enjoy taking risks to unbalance the game. White has three main replies: a) He can avoid all complications with 1 1 .i.b3, but forgoes any real chance of an opening advantage after l 1 . . .i.xc3 1 2.i.xc3 Wfb5 . The resulting equal position is reminiscent of the game Hjartarson - Cu. Hansen, Reykjavik 1 995, covered under variation C22 beginning with 9.0-0-0 lLlbd7 1 0.@b l . b) 1 1 .lLle5!? This was mentioned by Emms, who himself quotes the Serbian GM Solak. 1 1 . . .i.xa3 1 1 . . .i.xc3? 1 2.i.xc3 Wfa4 1 3.i.b4 is disastrous for Black. 1 2.bxa3 Wfxa3t 1 3.@b1 Wfb4t 1 4.@a1 1 4.@c 1 Wfa3t repeats. 1 4 . . . i.xc2 1 5 .E:c 1 i.g6 Black has obtained three pawns for a piece, and the position offers mutual chances.

We have been following the game Enders - Michaelsen, Bundesliga 1 993. The bishops find it hard to express themselves here, whereas Black's minor pieces both occupy stable posts. White can consider the plan of h3, ghfl and f4-5, but it will take some time to execute. The only fly in the ointment for Black is his king, which lacks a safe haven. Overall the position yields mutual chances.

25.'!Wf3 gh8 Black keeps sufficient counterchances. Conclusion In the basic position of this chapter, namely after l .e4 d5 2.exd5 '!Wxd5 3.lLlc3 '!Wa5 4.d4 lLl f6 5.lLlf3 .ifS 6 . .ic4 e6 7 . .id2 c6 8.'!We2 .ib4, we should briefly recall that 9.0-0 is not at all critical, and Black easily obtains a balanced middlegame. Instead the most promising plan for White, and also the most frequent, is linked with 0-0-0. For this purpose 9.a3 deprives Black of the option 9.0-0-0 lLld5, but at the same time White is showing his cards. Indeed, the interesting secondary lines 9.0-0-0 lLlbd7 1 O.lLlh4 and 1 O.mb 1 disappear as possibilities. The main line, 9.a3 lLlbd7 1 0.0-0-0 .ixc3 1 1 ..ixc3 '!Wc7 1 2.lLle5, demands great accuracy from Black. The second player indeed walks a tightrope following 1 2 . . . lLld5 1 3 . .id2 lLlxe5 1 4.dxe5 0-0-0 1 5 .g4 .ig6 1 6.f4, since the white plan of f4-fS constitutes a permanent threat. In this case 1 6 . . . h5 1 7.h3 hxg4 1 8.hxg4 E:xh 1 seems to be the best way to proceed, rather than 1 7 . . . '!Wb6. If Black wishes to spare himself the fastidious theoretical knowledge inherent to this variation, then 1 2 . . . b5!? represents a valid escape hatch.

We dealt with 8 .We2 in the previous chapter, while the knight jumps 8.lLldS and 8.lLle4 were the topic of the first chapter. To obtain a complete view of White's options, we will now address six minor alternatives. After a brief glance at 8.dS?! we shall look more deeply at A) 8.lLlh4, B) 8.h3, C) 8.a3, D) 8.lLleS and E) 8.0-0. 8.dS?! is basically dubious, since it merely helps Black's development. However the position remains balanced after 8 . . . WcS 9.dxc6 lLlxc6 1 O.We2. Here Black's safest option is 1 O . . . ie7, waiting to see which side White will castle. Nevertheless the more audacious 1 0 . . . 0-0-0!? or even 1O ... ixc2!? could prove playable as well.

A) 8.lLlh4 ig6 This is sounder than the provocative: 8 . . . ig4!? 9.f3 ihS No better is 9 . . . WhS 1 O.g3 ih3 1 1 .We2 (stronger than 1 1 .lLle2 id6) . White is now ready to castle long and to redeploy his offside knight via g2. One may wonder what the black queen and bishop duo are doing on the h-file. 1 O.We2 lLlbd7 1 1 .g4 ig6 1 2.0-0-0

White refrains from forcing matters, since 1 2.dS?! cxdS 1 3.lLlxdS WcS is not clear. 1 2 . . . ib4 1 3.@b 1 lLlb6 Or 13 . . . 0-0-0 1 4.a3 ixc3 1 s .ixc3 and the dark-squared bishop will soon be rerouted to g3. White has the better prospects.

Black has improved his pawn structure for free.

I. Gurevich - Morozevich, London 1 994. The mighty knight on d5 is worth a bishop. Trying to exploit the weakened d6-square would involve playing c2-c4, which would also concede some squares in the white camp.

White has the cwo bishops, but the black position is a tough nut to crack.

The various alternatives presented in this chapter are not bad, but they are not as critical as the options covered in the first cwo chapters. Black should not be afraid of his bishop being exchanged by tL'lh4xg6. Indeed, whether he obtains attacking prospects along the h-file or simply a solid position, in both cases chances will be shared after the recapture . . . hxg6. The hasty jump of the king's knight to e5 is not to be feared either. It will generally be neutralized by the natural developing move . . . tL'lbd7.

1 04


Meanwhile the quieter moves 8 .h3, 8.a3 and 8.0-0 all fail to create any early challenge to the black position, and the second player can easily complete his development in peace to reach a comfortable middlegame with balanced chances.

An unusual position; Black's bishop has been lured into a scary-looking pin at the cost of only one pawn. However it should be observed that the weakening of White's kingside makes it harder to profit from the pin. 1 4.WTe2 In the event of 1 4.g5 Black has a choice: a) 1 4 . . .

Kristiansen - Kamaras, Ballerup 1 98 5 . Black could have carried o n the fight, but converting his extra pawn would require really hard work.

Conclusion The extremely sharp variation A, in which White hounds the black bishop by 6 . .tc4 c6 7.lLle5 e6 8.g4 .tg6 9.h4, has been thoroughly investigated by theory, and Black has found several ways to get a decent game. Against the modest moves 6 . .te2 and 6 . .td3 (lines B l and B2 respectively) , White can equalize with a solid set-up based on . . . c6 and . . . e6, or can play more ambitiously with 6 . . . lLlc6 and a subsequent . . . 0-0-0. This latter possibility provides an argument for why Black should prefer the move order 5 . . . .tfS to the more limiting 5 . . . c6. The various minor lines after 6.lLle5 c6, such as 7.g4 or 7.lLlc4, have gone out of fashion and should not be feared either. Black can rather easily reach a level game against all of these secondary variations.

AIl we have seen in the first four chapters, the

main lines begin with 5 . . . .tf5 , which will in most cases be followed by . . . c6 on the following move. Before moving onto the main part of the present chapter, I should mention that the alternative 5 . . . c6 is equally popular, and in the great majority of cases the two moves will end up transposing. However, my personal preference is for the bishop development, as in a small minority of lines Black may still be able to benefit from the possibility of . . . tLlc6 intending . . . 0-0-0 (see, for instance, lines B 1 and B2 of the previous chapter.) For this reason I will not consider 5 . . . c6 independently. Let us now move on to the main subject of the present chapter: Black's unusual options on move 5. Apart from the main set-up examined in the first four chapters, the second player has tried plenty of other ideas, with varying results. We will study four main branches: A) S .tf5 (without an early . . . c6) , B) S .tg4 C) S tLlc6?! and D) S tLle4?!. •••

This suspicious-looking move probably leads only to a small edge for White.

Black only has two minor pieces and a pawn for the queen, but his position is compact and d4 is weak. White's supremacy does not look so great to me here. 1 O.'LJxg6 With his bishop on g6 rather than fS , Black can meet 1 0.'LJc4?! \Wc6 1 1 .'LJd6t with 1 1 . . .i>e7!oo. 1 0 . . . hxg6 Now White can force a transition into a favourable endgame as follows:

It should lead to a level position: 1 O . . . exd5 1 O . . . �bd7 is playable as well, in which case White's only hope of an advantage is 1 1 .�d4.

Nowadays it has a bad reputation and is seldom employed, but only a minority of games have featured what I believe to be the critical test of it.

Conclusion The majority of the lines treated in this chapter are old-fashioned and dismissed by current theory as being bad for Black. The secondary line 5 . . . lLlc6?! is almost forgotten nowadays. White is generally aware of the nasty 6.id2, which leads to a pleasant ending for him practically by force. The line 5 . . . lLle4?! is basically dubious. White can obtain an advantage with precise play, as his opponent will find it hard to deviate from the games Nevednichy - Afek and Dranischnikov - Prie. On the other hand 5 . . .ig4 is not so bad. I have personally used this line in four classical games against three GM's and an 1M, and was never confronted with the critical response, which suggests that this variation may serve as a decent surprise weapon.

We will now turn our attention to the early development of the queen's bishop with 5 .id2. This scheme of development is closely related to 5 .ic4 (the subject of the next chapter) and the two moves can frequently transpose to one another. In both cases White hopes that the delayed development of the g I -knight will give him some additional options. Black can react in a number of different ways, but I would tend to agree with the assessment of the French specialist of the Scandinavian, Grandmaster Eric Prie, who recommends a set-up founded on an immediate 5 . . . ig4. White has several possible responses, the most critical being 6.£3 if5 7.g4 ig6, and now the ultra-aggressive B.f4 e6 9.f5!?, which is analysed in variation B44. The resulting positions are complex and challenging for both sides, but my analysis indicates that Black's prospects are quite healthy. 1 .e4 d5 2.exd5 Wfxd5 3.lLlc3 Wfa5 4.d4 lLlf6 5.id2

In both cases Black can hope for nothing more than a transposition to a standard line, while White's move order has provided him with some genuinely promising additional options.

The drawbacks of this slow move were convincingly exposed in the following model game of Vladimir Kramnik. Neither . . . �a5-b6 nor . . . c7 -c6 were bad moves in isolation, but together they make for a bad combination. Some of the following annotations are borrowed from Pril! in ChessBase Magazine.

7 .tc4 .tfS 7 . . . .tg4? is hit by the trivial B . .txf7t dfxf7 9.lLle5t Q;>gB 1 0.lLlxg4 �xd4 and now either 1 1 .lLle3 or 1 1 .lLlxf6t exf6 1 2.0-0 gives White a sizeable edge. •

Black cannot get away with taking on b2. Let's see: 7 . . . �xb2? B.lLle5! The proof of the preceding comment! Also BJ::\ b 1 ! comes to the same thing. B . . . e6 9.0-0 .te7 1 O.E:b 1 �a3 1 1 .E:e 1 ! 1 1 .lLlb5? would trap the queen, but the price to pay is too high: l 1 . . .cxb5 1 2 . .txb5t .td7 1 3.lLlc4 �xa2! 1 4.E:b2 .txb5 1 5 .E:xa2 .txc4-+ 1 1 . . .0-0 1 2.lLle4 This eliminates one of the few defenders of the black castled position, at the same time preparing a rook lift along the third rank. The whole white army will join the assault against the enemy king and there is already no satisfactory defence.

8.We2! Black's problems are already starting to become apparent: the pawns on b2 or c2 are hardly edible, so White develops normally without harm. In other words, the queen's retreat to b6 has effectively wasted a tempo which could otherwise have been spent on a useful developing move. a

7.�c4?! As we will soon see, it is more precise to play: 7.h3! This may not lead to an advantage, but it reduces Black's options by ruling out the set up seen in the main line below.

Chapter 6 - 4 . d4 tLJf6 S .i.d2 7 . . . i.hS 7 . . .i.xB 8 .WfxB lOc6? is met by the powerful 9.dS! lOd4 1 0.Wfd3 eS l 1 .lOa4. Confronted with the threat of c2-c3, Black now blundered by 1 1 . . .e4? 1 2.Wfc4 1 -0 Lanzani - Ricci, Milan 2004. The alternatives weren't much brighter however: 1 1 . . .Wfd6 1 2.c3 bS 1 3.cxd4 bxa4 1 4.WfbSt lOd7 I S .0-0-0± or 1 1 . . .Wfa6 1 2.Wfxa6 bxa6 1 3.0-0-0 lOxdS 1 4.i.xa6± 8 .i.c4 lObd7 8 . . . lOc6? loses a piece to 9.g4 followed by l O.lOa4. 9.g4!? This committal move is not strictly necessary because Black was not yet threatening . . . i.xB followed by . . . Wfxd4, but testing the viability of the black set-up is natural. In this case it will be waterproof, therefore I would suggest that the alternatives 9 .Wfe2!? and 9.a4!? deserve attention. 9 . . . i.g6 1 0.gS

White should win in the long run.) l 1 .lOdS Wfd6 1 1 . . .Wfe6t? 1 2.lOeS would not be vety smart from Black. 1 2.i.b4 Wfc6 1 3.lOeS lOxeS 1 4.i.b5 White has put all his energy into going for the enemy queen, but in doing so he has completely neglected the harmony of his position. 1 4 ... 0-0-0 1 5 .i.xc6 1Oxc6 1 6.c4 e6 1 6 . . . 1'%xd5? 1 7.cxd5 1Oxb4 1 8.Wfa4 1 7.i.xf8 1'%hxfB 1 7 . . . exd5!? is also interesting. The position can be assessed as unclear, although with . . . lOxd4 coming on the next move I would rather be Black.

7 ... e6 8.h3 ha!? 8 . . . i.h5 is similar to the previous note. The text move, in conjunction with Black's next, is an interesting attempt to question White's chosen move order. 9.Wfxf3 1O c6! With the d4-d5 advance prevented, this is now playable.

Chapter 6 - 4 . d4 tLl f6 S .J.d2 do so. Let's study BI) 6.ttJO, B2) 6.ttJge2 and B3) 6.J.e2, before turning to the critical B4) 6.0. 6.ttJe4? leads to an endgame where White is fighting for a draw. 6 . . . J.xd 1 7.ttJxf6t gxf6 8.J.xaS J.xc2 9.!:k1 (Or 9.J.xc7 ttJc6 1 0.dS? E:c8 1 1 .E:cl J.e4 1 2.dxc6 E:xc7+) 9 ... J.e4 1 0.E:xc7 ttJc6 1 1 .f3 J.dS The as-bishop is attacked and the white rook is cut off from its camp. 1 2.J.bS ( 1 2.J.c3 E:b8) 1 2 . . . a6! 1 3.J.xc6t J.xc6 White is in trouble.

BI) 6. ttJ O The position after this self-pin can be categorized under the variation 4.d4 ttJf6 S .ttJf3 J.g4, as analysed in line B of the previous chapter. AB 6.J.d2 is a secondary move in that position, Black should be able to equalize rather easily.

6 ... ttJbd7 6 . . . ttJc6? transposes into the dubious line B of the previous chapter. 6 . . . WfhS?! is not to be recommended either: 7.J.e2 ttJc6 8 .h3 0-0-0 9.0-0 J.xf3 (9 . . . eS?! 1 0.dS!) 1 O.J.xf3 WffS 1 1 .J.xc6 bxc6 1 2.Wfe2 with a plus for White. 6 . . . e6 looks fine though. Then after 7.h3 J.hS 8.g4 J.g6 9.ttJeS we have reached another position that could have arisen from the aforementioned S . . .J.g4 variation, where White has opted for 9.J.d2 instead of the critical 9.h4!. Black can choose berween 9 . . . Wfb6 or 9 . . . ttJbd7°o.

7.h3 7.J.c4 now allows Black extra options. Apart from 7 . . . 0-0-0 8 .J.xf7?! eS!, he can contemplate either 7 . . . WffS or 7 . . . WfhS , after which 8.ttJbS? is foolhardy to say the least, as Black seizes the initiative with 8 . . . 0-0-0 9.ttJxalt 'it>b8 1 O.ttJbS eS.

8 ... 0-O-O?! Playing with fire. 8 . . . Wfb6! is okay for Black, as we saw in variation A2. 9.g4 9.ttJb5 is interesting but not altogether convmcmg. 9 . . . Wfb6 1 O.a4 mb8 1 1 .g4 J.g6 1 2.J.f4 ttJe8 Black should succeed in unravelling while repelling the enemy pieces, for example: 1 3.Wfe2 a6 1 4.a5 Wfc6 l S .ttJc3 e6 1 6.0-0-0 J.b4 1 7.dS exd5 1 8 .ttJxd5 J.d6= 9 ... J.g6 IO.Wfe2 e6?! Again the cautious 1 0 . . . Wfb6 is more to the point. 1 1 .ttJd5! 1 1 .0-0-0?! justified Black's play after 1 1 . . .J.b4 1 2.a3 J.xc3 1 3.J.xc3 Wfb6, Leon Hoyos - Prie, Villeneuve Tolosane 2006. Black had good control of the light squares in return for the rwo bishops. AB pointed out by Prie, Black usually gets this kind of position with a pawn on c6 rather than c7. Thus d6 is not weakened and Black may utilize the c6-square for his pieces. 1 l ... Wfa4 12.ttJxc7!

After White's 1 1 th move we reach a critical position.

Black has a minimal material disadvantage, with a knight and a rook for the enemy queen. On the other hand he benefits from several positional features, such as a better pawn structure and a stronghold for a knight on d5. Prie now analyses a dubious knight tour designed to grab the c3-pawn, but I would prefer the simple: 1 4 . . . 0-0 When White has no more than a small edge.

Conclusion The line considered in this chapter, 4.d4 lDf6 5 .id2, can be tricky if Black is unfamiliar with the nuances this move order introduces. By delaying or even omitting lDf3, White leaves his kingside pawns free to advance, which can be dangerous if Black pretends this chapter is j ust like the main lines we have already seen. Now 5 . . . %Vb6!? is an interesting sideline, but the main line I recommend is to cross White's plans with 5 . . . ig4. The critical line is B44, which is 6.f3 if5 7.g4 ig6 8.f4 e6 9.f5!? This is undeniably wild, but Black has level chances in the melee.

This move is played with the same basic idea as 5 .�d2 from the previous chapter. White hopes to obtain an improved version of a standard line by delaying the development of his knight on f3. However, the choice to develop the light-squared bishop first this time can give rise to some independent possibilities for both sides. As the reader may have observed throughout the previous chapter, it is in Black's interest to provoke his opponent by playing . . . �c8-g4. We saw that this might either yield a tempo to develop, while in the event of the principled reply f2-f3 White gains time for his kingside expansion but weakens the a7-g 1 diagonal as well.

From this, our starting position for the chapter, we will begin by considering the slightly unusual A) S 4:J c6!? , before moving onto the main line of B) S �g4 . Before doing so, let us briefly check a few other possibilities: •••

5 . . . c6?! is once again unattractive, for exactly the same reasons as discussed in the previous chapter. It is a similar story after 5 . . . �f5?! 6.�d2, when the threat of 4:Jd5 means that Black probably has nothing better than

Black has two pawns for the exchange but his king is rather lonely for the time being. If he can consolidate his position then he will stand at least equal, so the question is whether White can prevent that from happening.

The whole line with 7 . . . ie6!? requires further practical testing. It seems to me that Black's position is perfectly viable, and I have identified a number of improvements and other potential areas requiring further investigation.

Conclusion Black has a few interesting ways to meet the system with 4.d4 and 5 .ic4. He can unbalance the game with 5 . . . lLlc6, which seems to lead to unclear complications. The more popular 5 . . .ig4 will usually provoke the weakening f2f3 during the next move or two, thus leading to complex, double-edged positions in which Black seems to be holding his own.

Some players have experimented with leaving the g8-knight where it is, even though . . . lLlg8-f6 is as natural a developing move as one could wish for. This line has acquired the catchy name of the Konigspringerzuruckhal tungspolitik (which can be translated as: "policy of not developing the king's knight") variation. One of Black's ideas is to avoid lLlc3-d5xf6t, while in certain variations he might even be able to consider developing the knight on e7. This concept was recommended by GM Matthias Wahls, but the Konigspringerzuruckhaltungspolitik suffers from one essential drawback: it gives White the opportunity to seize space on the kingside, which increases his options without any significant counterbalancing gain for Black.

White is a tempo up compared to a line of the Caro-Kann, namely l .e4 c6 2.d4 d5 3.lLlc3 dxe4 4.lLlxe4 .tf5 5 .lLlg3 .tg6 6.h4 h6 7 . .tc4 e6 8.lLlge2 lLlf6 9.lLlf4 .th7 1 O.We2, having acquired the extra move .tc 1 -d2. This argument may cool down even Scandinavian fanatics, but there is another way to look at this annoying observation. Indeed, Black is scoring well in the theoretical position (i.e. with the bishop still on c 1 ) because the white position is merely optically menacing. Sacrifices on e6 are usually unsound, which makes the black camp fairly solid.

9 lLl e7 10.0-0-0 Black has a large choice at this juncture, but nothing is satisfactory. The unfortunate paradox of his set-up is that the squares fS and dS are the most controlled ones of the board, and yet it is precisely the pawn breaks f4-fS and d4-dS that will hurt! ..•

Conclusion In my view the Konigspringerzuriickhaltung spolitik has not been completely refuted, but Black is walking a tightrope just to stay alive. He can hope to lure his opponent onto less well-trodden paths and confuse him, which is a reasonable idea from a practical point of view. Apart from that, a Scandinavian player will draw no benefit from keeping his gB-knight at home, while depriving himself of various use ful resources.

We will now examine the so-called "Short System", which is characterized by the moves l .e4 d5 2.exd5 "Wxd5 3.tLlc3 "Wa5 4.ic4 tLlf6 5 .d3, and is named after the British GM who helped to popularize it after winning several nice games. In comparison with variations studied so far, the outing of the light-squared bishop to c4, in conjunction with the seemingly modest d2-d3, introduces a rather aggressive and flexible system. White will usually continue with a quick id2 followed by "We2 and 0-0-0, although short castling can sometimes be considered too. The first player enjoys maximal flexibility with his kingside pieces; thus he might play f4 followed by tLl8, or alternatively tLl8 or tLlge2 without touching the f-pawn. Pushing the d-pawn only one square yields pros and cons for both sides. On the plus side for White, the light-squared bishop is protected, a future tLlc3-e4 is made possible and moves like . . . tLlc6 will not attack the d-pawn. On the other hand White controls less space in the centre and lacks the often powerful d4-d5 break. Black might also profit from the unguarded e5-square, which can facilitate the transfer of his pieces. For instance, the black queen will tend to be in less danger after the usual ic l -d2.

From the diagram position Black's two main options are A) 5 c6 and B) 5 ig4 . •••

This is a perfect example of the troubles Black may experiences in the present variation.

Black was under unpleasant pressure in Short - Gonzalez, Banyoles 2007, although to his credit he eventually held on for a draw after the Englishman missed a few opportunities to clinch victory.

the knight obstructs the queen from defending the bishop on e7, which in turn makes it more difficult for Black to castle as f4-5 will simply win a piece.

Black has an inferior pawn structure and a stupid-looking bishop on g6, and yet the position offers mutual chances.

This is the obvious answer to Black's last move, even though the weakening of the a7gl diagonal should not be underestimated. Black must now decide between B21) 6 ... i.f5 and B22) 6 i.d7. Indeed, 6 . . . i.h5 only limits Black's choice afterwards, while there is no real point in stopping f3-f4.

7 . . . e5?! This is inaccurate. We may also briefly note that 7 . . . tLlc6 8 .id2 �c5 9.a3 is more pleasant for White. The correct idea was the flexible 7 . . . tLlbd7!N, which allows Black to choose between . . . e6 and . . . e5 depending on circumstances. In that case the chances would remain about equal. 8.tLlg3 i.g6 9.i.d2 tLlbd7 This was Belkhodja - Chabanon, Marseille 200 1 , and here White could have obtained a strong initiative with: 1 0.f4!N Instead the game continuation of 1 0.�e2?! 0-0-0 was only equal. 1 O . . . exf4 l 1 .tLld5 �c5 1 2.�e2t d8 1 3.tLlxf4 i.d6 1 4.0-0-O With an unpleasant position for Black.

7 Wb6!? This is often a risky square for the queen in the Scandinavian, but in this position the idea is quite viable and has scored heavily in the few games in which it has been played. Nevertheless the following idea is also quite playable: 7 . . . c6 B.We2 B.llJd5 WdB 9.llJxf6t gxf6, Sammalvuo Wegner, Jyvaskyla 1 993, is not to be feared. Black would then have obtained the same structure as in the Caro-Kann line with 1 .e4 c6 2.d4 d5 3.llJc3 dxe4 4.llJxe4 llJf6 5 .llJxf6t gxf6, where he has avoided the nasty system with g3 and �g2.

Conclusion The Short System, l .e4 d5 2.exd5 V9xd5 3.lLlc3 V9a5 4 . .ic4 lLlf6 5 .d3, may give rise to an early tactical skirmish. This is generally linked with Black's light-squared bishop making a provocative lunge to g4, which White usually meets with a double-edged pawn avalanche on the kingside. In contrast to lines that include the d2-d4 push, the black queen often has the c5- and e5squares available. As a consequence, the queen is in less danger of running short of space. From a theoretical point of view, Black can obtain decent chances, but he has to pay close attention to the details if he embarks on . . . g7g6 or . . . c7 -c6 prior to . . . .ig4. The games Cicak - Hernando Rodrigo and Short - Reprintsev perfectly illustrate this assertion.

In this chapter we will turn our attention to a modest system of development in which White delays any action with his d-pawn. The whole idea appears rather timid, but it should not be underestimated. White keeps some flexibility regarding the future of his light squared bishop and d-pawn, so Black should take care not to allow a transposition into an unfavourable line.

From here we will consider A) 4.h3 and B) 4.lDf3.

A) 4.h3!? If White wishes to avoid the . . .�g4 pin at all costs, then this is the way to do it, although I hardly need state that it is objectively harmless. Against such a slow set-up Black can do almost anything, so I will j ust mention one interesting practical example.

Chapter 1 0 - 4 . ct:l f3 (and 4 . h3) This position might also b e reached via the move order l .e4 d5 2.exd5 �xd5 3.lLlf3 �g4 4.lLlc3 �a5 (see variation B2 of Chapter 1 2) , although the present sequence has enabled White to avoid the problematic 4 . . . �e6t. In any event, the following game featured an original treatment from White: 5 .h3 �h5 6.g4 �g6 7.�g2 lLlc6 S.O-O 0-0-0

The position now resembles the ones arising after 4.g3 in Chapter 1 1 . White's tempo-gai ning development on the kingside has also created weaknesses, so Black certainly has a share of chances here. 9.a3 e5?! A reply in the centre often constitutes the correct response against action on the wing. Here, however, a counter-attack on the opposite flank was more appropriate: 9 . . . h5!N 1 O .g5 ( l 0 .b4 lLlxb4 1 1 .1"1b l lLlc6 is not convincing for White, while after 1 0.1"1b l ? his assault could well arrive too late, as the following sample line suggests: 1 O . . . hxg4 I l .hxg4 lLlf6 1 2.b4 �b6 1 3.lLla4 �a6! 1 4.lLlc5 �c4 and White is in trouble.) 10 . . . h4 with complex play. 1 O.1"1b l �c5 I l .d3 White probably rejected the tempting I l .b4!N in view of 1 1 . . .�xc3 1 2.dxc3 1"1xd l 1 3.1"1xd 1 �xc2, but the reality is that 1 4.b5! is strong.

1 1 . . .e4 1 2.lLlh4 Not 1 2.�e3?! exf3 when Black will obtain three minor pieces for the queen. 1 2 . . . exd3 1 3.lLlxg6 dxc2 1 4.�xc2 hxg6 1 5 .�e3 �e5 1 5 . . . � c4 was perhaps a better defensive try. 1 6.1"1fe l �c5 1 7.b4 �xe3 I S .1"1xe3 White has an overwhelming initiative.

5.�e2 This shy move allows Black more options than the standard 5 .d4. Fianchettoing the dark-squared bishop, for instance, becomes perfectly valid.

5 ... c6 One of the points of this move is to provide a convenient retreat for the queen in the event that White plays b4. Its small drawback, compared to the immediate 5 . . . �g4, is that White can now reply 6.h3, but that is unlikely to strike fear into the hearts of Scandinavian players. Here are some other possibilities:

White has a pair of bishops but less influence in the centre and no target for the moment. The position is close to equal. It should be mentioned that the following continuation is not advisable: 5 . . . ig4?! This move is premature, and enables White to fight for the initiative thanks to the possibility of b2-b4. 6.b4 6.h3 ih5 7.b4 is also possible, and leads to similar play. 6 . . . \Wb6 7.a4 c6 Another game continued 7 . . . e6 8 .a5 (8.�b l is a logical alternative, preparing b5.) 8 . . . \Wd6 9.b5 ie7 1 0.h3 ih5 1 1 .�a4!? \Wd8 1 2.g4 ig6 1 3.h4 h6 1 4.lDe5 ih7 Filipek - Nezar, Belgium 2002, and here White should have played 1 5 .if3!N intending 1 5 . . . lDd5 1 6.lDxd5 exd5 1 7.a6 bxa6 1 8 .�d4 with a large advantage. 8 .h3 ih5 9.0-0 e6 I O.b5 ib4?! 1 1 .�b l ixc3

Conclusion If, after the series of moves l .e4 d5 2.exd5 Vlixd5 3.lLlc3 Vlia5 4.lLlB lLlf6, White restricts himself to the modest 5 .fie2, his opponent can certainly choose from a greater variety of possible replies than after the main 5 . d4. The choice between 5 . . . c6, 5 . . . lLl c6, 5 . . . fig4 and even 5 . . . g6 is largely a matter of taste. From White's point of view, the interesting b2-b4 thrust may give some initiative on the q ueenside, once Black has developed his q ueen's bishop. Still, as long as Black takes care not to allow this idea under especially favourable conditions, he should not encounter any real problems in the opening.

In this chapter we will examine two very different flank systems, beginning with the sacrificial 4.b4?!, followed by the calmer 4.g3. These two marginal lines have, perhaps not surprisingly, not been studied deeply by theo reticians. The reason in the former case is rath er obvious, since White's compensation for the sacrificed pawn is questionable, particularly against a black formation including a kingside fianchetto. In the second line, a certain amount of opening knowledge will be beneficial for both players. Black can equalize in various manners, but must avoid certain pitfalls. For instance, a premature development of the c8-bishop might run into a quick b2-b4 thrust, which would increase the influence of the bishop on g2 without losing a pawn. White should also remain cautious though, as in some cases a premature b4-b5xc6 can be answered by the simple . . . tLlxc6, when White's queenside demonstration has only helped to accelerate his opponent's development. Without further ado, let us analyse both A) 4.h4?! and B) 4.g3.

A) 4.h4?!

f

g

h

This gambit, which was occasionally tested in simultaneous exhibitions by Lasker or Capablanca, is strategically unfounded. It is true that White can activate his queen's rook on b 1 this way, and thus hamper the opponent's development, but that alone is not worth a pawn. The black position contains no weaknesses and with accurate play he will be able to fight for an edge. It is worth adding that I only found a single instance in which a player rated over 2400 dared to use this gambit in a classical game.

4 Wi'xb4 I am not even going to analyse 4 . . . Wi'e5t and 4 . . . Wi'b6, even though both moves have been tested. Black should definitely take the pawn there are no two ways about it. •••

5J�bl Wi'd6 6.d4 6.tLlf3 will usually transpose after 6 . . . tLlf6 7.d4, as White finds it hard to do without one move or the other. 6 tLlf6 7.tLla a6! I believe this to be more accurate than the natural 7 . . . e6, when White obtains reasonable play: 8 .�d3 a6 9.0-0 tLlbd7 1 O.ge l ( 1 0.�g5 intending �h4-g3 and perhaps also tLle4, deserved consideration.) 10 . . .�e7 1 1 .Wi'e2 c5 1 2.d5!?

8.g3! This is White's best chance. The situation can be compared with the line 3 . . . �d6 4.d4 tLlf6 5.tLlf3 a6, at which point 6.g3 is White's main line. The present position is identical, except that the white rook is on b l and the b-pawn is missing, thus making the kingside fianchetto all the more logical. The alternatives are unappetizing for White:

8 ... b6 This is solid and safe, but Black can also consider the peculiar-looking 8 . . . �c6!?N, with the possible continuation 9 .�d3 ie6 1 O.ig2 ic4, impeding White's castling. 9.ig2 ib7 10.0-0 e6 1 1 .tLle5 ixg2 12.�xg2 ie7 13.�f3 ga7 14.gdl 0-0 This position was reached in Ivanets Minakov, Kiev 2005.

The flexibility of Black's set-up becomes apparent after 8 .id3 g6! 9.0-0 ig7, when White has problems demonstrating compensation. After castling, Black will follow up according to his opponent's reaction, by means of. ..tLlc6, . . . c5 or . . . b5, reaching a normal looking position with a pawn safely in the bank.

Fianchettoing the light-squared bishop constitutes an original and interesting treatment

224


of the opening from White. The first player spares himself the effort of studying a lot of theory, while still maintaining the prospect of a rich struggle. Indeed, early exchanges of both pieces and pawns are rare in this system, and each camp can develop his pieces according to various schemes. Even if the white set-up is not theoretically dangerous, its flexibiliry makes it a tricky line to meet, especially if Black is unprepared. Before moving on, it is worth noting that White occasionally plays 4.ttJge2 with the idea of following up with g3. I will not consider this line independently, since the outcome will almost certainly be a transposition to one of the lines presented below. The only difference is that White has committed his knight prematurely, whereas in the main line he can consider putting the knight on f3 instead of e2. We will consider two main replies for Black. He can respond to his opponent's last move in kind with Bl) 4 ... g6, but the most natural and popular move is of course B2) 4 ttJf6. Black has occasionally tested a couple of rather more exotic replies as well. •••

The aggressive 4 ... h5?! seems inappropriate with almost the entire black army still in their starting blocks. 5.ttJf3 ttJc6 6.ig2 h4 A consistent follow-up, but Black will never get enough in return for the pawn. 7.ttJxh4 g5 8.ttJf3 ih3 9.ixh3 Elxh3 1 0.d3 After this simple move even covering g5 proves a challenge. 1 O . . . g4 1 1 .ttJgl Wh5 1 2.ttJxh3 Wxh3 1 3.ie3 Wg2 1 4.lt>d2!

If Black wishes to play with . . . e7 -e5 , then it is not necessary to restrict the scope of the g2bishop by means of . . . c7-c6. On the contrary, as the following game will show, it can prove useful to have kept the c6-square vacant for the queen's knight.

6.tLlge2 6.tLlf3 is also playable. From this square the knight exerts a slightly greater influence over the centre, but also obstructs the g2-bishop as well as the f-pawn. Play may continue 6 . . . .id6 7.0-0 0-0 8 .d4, Dvorak - Mlensky, Znojmo 2002, and here Black should proceed as in the main line below with 8 . . . tLlc6N, with the possible continuation 9.d5 (Hoping to utilize the position of the f3-knight in a positive way.) 9 . . . tLlb4 (9 . . . tLle7 is suitable too) :

Finally we come to a rare system, which is however quite in the "Scandinavian spirit". In deed, with the early . . ..tg4 and . . . lLlc6 Black speeds up his development and gives priority to dynamic piece-play. With . . . 0-0-0 he then reveals his bellicose intentions. It is worth mentioning that Black can implement the same scheme by means of 5 . . . lLlc6, as 6 . .txc6t?! bxc6 is surely not in White's interests, while 6.h3 looks like a tempo "half-wasted" .

This may be acceptable too, but the following line works out in White's favour: 1 O . .td2 Wb6 1 1 .:i:!b 1 .tb4 In the event of 1 1 . . . .td6 (intending either 1 2 . . . lLld4 or 1 2 . . . e4 1 3.dxe4 .txg3) White replies 1 2.g4! .tg6 1 3.g5 ttJd7 1 4.ttJd5 (or 1 4.b4!?) 14 . . . Wa6 (or 14 . . . Wb5 1 5 .c4 Wa6 1 6.b4) 1 5 .b4 with some initiative. 1 2.a3N This is better than the weakening move 1 2.g4?! as played in Day - Rositsan, Toronto 1 998. 1 2 . . . .txc3 1 3.bxc3

We now reach a final division, where White can choose either B222 1) 6.lLla or B2222) 6.lLlge2.

B222 1) 6.lLla lLlc6 7.h3 And not 7.0-0? Wh5 ! when White is already in trouble.

Conclusion One major theme in this chapter is the b2-b4 thrust, although it seems a little premature on move 4 since after 4.b4 VNxb4 5 .E:b l VNd6 White's compensation for the pawn is uncertain. On the other hand, pushing the b-pawn becomes stronger once White has posted his light-squared bishop on g2. From here it eyes the b7-pawn, and the attempt to bolster the diagonal with . . . c7 -c6 might eventually be met by b4-b5xc6. It is worth noting that the preparatory move E:b 1 is not always necessary, but can certainly prove useful. Overall I would say that the g3-system may suit creative players who are keen on avoiding heavy theory, such as the Lithuanian Grandmaster Rozentalis. We have seen that Black has numetous ways to reply, and his choice is foremost a question of style. For those who are willing to try and shake their opponent, I would recommend the typically "Scandinavian" scheme of development, . . . lLlc6/ . . . .ig4 and . . . 0-0-0.

By deferring the natural 3 .it:k3, White is aiming to establish a pair of pawns on c4 and d4. This would control the centre well, and often give White an initiative linked to the d4-d5 push. This pawn tandem constitutes the focal point of the entire 3 .d4/3.tLlf3 complex, since it will also provide Black with his main target for counterplay. White's two third moves will sometimes merge, but by starting with the development of the king's knight White avoids the interesting 3 . . . e5. We will see over the course of the chapter that Black's most promising methods against both moves will be based on quick development combined with pressure against the enemy centre. In many cases, the presence of opposite-sided castling will add an extra level of excitement to the already tense and unbalanced positions.

1 .e4 d5 2.exd5 Wxd5 If he wishes to avoid the theory inherent to 3.tLlc3 White only has two sensible replies, A) 3.d4 and B) 3.tLlf3. These two variations often melt together if Black decides to answer them with the scheme . . . tLlc6/ig4/0-0-0, but they also contain their own individual features. Before we dive into the study of these lines, let's have a brief look at two rare alternatives: 3.c4? This ugly-looking move may be playable in a rapid game. That is, as long as Black fails to opt for: 3 . . . \We4t! After a continuation such as 3 . . .\Wa5 4.tLlf3 there would follow ie2, 0-0, and d4, perhaps with the insertion of tLlc3 if White has to stop . . . e5-e4 at some point. In this case White's position would be j ust about acceptable. The text move, on the other hand, simply refutes White's third move. 4.\We2

This is more or less forced, since the alternatives 4.tLle2? \Wxc4 and 4.ie2?! \Wxg2 5 .if3 \Wg6 both lose a pawn for no real compensation. 4 . . . \Wxe2t 5 .ixe2 tLlc6 6.tLlf3 e5 Black stands better in this queenless middlegame, as White has no compensation for his backward d-pawn and the weakness of the d4-square. 3 .\wf3 Strangely White feels more attracted by the aforementioned lunge with the c-pawn (97 games in my database) than by this modest move (67 instances) , although the latter at least maintains the equilibrium rather than putting White on the defensive immediately. 3 . . . tLlf6 From here a possible continuation is: 4.tLlc3 \Wa5 4 . . . \Wxf3 5 .tLlxf3 is level. 5 .h3!? tLlc6 6.ib5 id7 7.tLlge2 0-0-0 With mutual chances.

Chapter 1 2 - 3 .d4 and 3 . tD f3 moves, as they are bold and ambitious. A neu tral move such as 3 . . . lDf6 is not disastrous, but it is likely to allow White the set-up he wants - a solid centre with d4 and c4.

This energetic action in the centre usually leads to simplifications. It can thus be recommended to players who hanker for a less complex position than the ones arising from 3 . . . lDc6.

4.dxe5 The attempt to chase the enemy queen from the centre by: 4.lDc3 Should be met by: 4 . . . i.b4 Instead, taking the d-pawn would be too risky. Now we have the possible continuation: 5.lDf3 In the event of 5 . a3 i.xc3t 6.bxc3 lDc6 Black's healthier pawn structure and speedy development easily compensates for White's pair of bishops. 5 . . . exd4 Black can also consider 5 . . . lDc6, transposing to variation B 1 1 beginning with 3 . . . lDc6. 6.WI'xd4

237

6.lDxd4 transposes to 4.lDf3 below. 6 . . . WI'xd4 7.lDxd4 lDe7 And Black is j ust a little worse in the queenless position. 4.lDf3 exd4 5 .lDxd4 After 5 .lDc3? Wl'e6t 6.lDe2 c5 Black was already better in Balogh - Goreskul, Gyongyos 1 999. A more reasonable alternative is 5.WI'xd4 lDf6 6.lDc3 Wl'xd4 7.lDxd4. In this position White seems to have a small plus at first sight, but after the logical 7 . . . i.c5 B.lDdb5 (B.i.e3 invites B . . . lDg4) B . . . lDa6 9 .i.f4 0-0 (or 9 . . . i.f5!?) this proves illusory. 5 . . . i.b4t!? This is intended to lure the c-pawn forwards, thereby depriving the b I -knight of its best square. The natural 5 . . . lDf6?! runs into problems after: 6.lDc3 i.b4 7.WI'e2t! Wl'e4 (perhaps Black should consider 7 . . . i.e6 or even 7 . . . i>f8, although both of these options also have obvious defects) B.i.d2 Wl'xe2t 9 .i.xe2 And at this early stage of the game, Black found himself defending a nasty ending in Sevillano - Wahls, Biel 1 993. White has a simple and powerful plan of development involving �he 1 combined with placing his bishops on f3 and f4, from where they will exert unpleasant pressure against the enemy queenside. 6.c3 6.lDc3 should be met by either 6 . . . lDe7 or 6 . . . lDc6; but obviously not 6 . . . lDf6?! which would transpose to the above note. 6 . . . i.c5 7.i.e3 This position was reached in Zellweger Droessler, Bavaria 2002, and now after the natural 7 . . . lDf6N the position is roughly equal. 4.i.e3

The text move unbalances the position more, without compromising on soundness. B.O-O Axc3 9.bxc3 This position was reached in Balla - Gereben, Budapest 1 93 5 , and several subsequent games. Wahls j udges the white position to be preferable, but I would rather speak about mutual chances after: 9 . . . liJf6!?N Surprisingly this natural move has not yet been tested. So far Black has always played either 9 . . . e4 or 9 . . . exd4. 1 0.c4 In the event of 1 OJ%b l Black can get away with 1 O . . . Wlxa2. 1 0 . . . WIe4 I 1 .Ad3 I I .d5 will come to the same thing after 1 1 . . .Axf3 1 2.gxf3 Wlh4 1 3.Ad3. 1 1 . . .Axf3 1 2.gxf3 Wlh4 1 3 .d5 liJd4!? With the possible conclusion: 1 4.c3 liJe6! 1 5 .dxe6 e4! 1 6.fXe4 l:hd3 1 7.Wlxd3 Wlg4t I B.mh l Wlf3t= And the game ends with a perpetual.

for instance: 5 . . . Ag4 6.Ae3 (6.liJd2 liJc6 7.liJgf3 Wle6 is balanced) 6 . . . Wlxb2!? 7.liJd2 (7.Ad4?! does not impress after 7 . . . Wlb4t B.c3 Wle7 with a healthy extra pawn, and 7.Axg4 Wlxa l B.AcB does not work due to B . . . Wlb2.) 7 . . . AfS BJ:!b l And White has a dangerous lead in development for a small material investment.

5.mxdl c!t:Jc6 5 . . . Ac5! ? could also be considered. 6.-*.£4 This seems like the natural choice, although several others have been tried. It is a bit early to commit the king's knight with 6.liJf3, and Black is doing more than okay after 6 . . . Ag4 or 6 . . . Ac5 . 6.Ab5 i s also not especially challenging after: 6 . . . Ag4t (or6 . . . Ad7 7 .liJf3 liJxe5=) 7.f3 O-o-ot B.Ad2 Ad7 9.-*.xc6 (otherwise . . . liJxe5 will follow) 9 . . .Axc6 1 0.liJh3 h6 (preventing the plan of liJg5 and e6) l 1 .liJf2 g5 1 2.!!e l liJe7

This move represents the only way for White to guarantee holding on to the eS-pawn. It creates serious weaknesses in White's camp and is therefore criticized by various sources. My own view is that the advance of the f-pawn does not in fact compromise White's position excessively, although I must emphasize that Black can certainly claim adequate compensation after a subsequent . . . 0 -f6, opening the centre. 6 . . . i.fS 6 . . . i.g4t 7.i.e2 O-o-ot can be adequately met by 8 .i.d2 lLlh6 9.lLlf3 i.cs 1 O.c;t>c1 followed by lLlc3. White will try to lighten his defensive task by exchanging pieces, while parrying any direct threats as they arise. 7.lLlf3 7.c3 is less solid, as demonstrated by the following duel: 7 . . . 0-0-ot 8.c;t>el f6 9.i.bS fXeS 1 O.i.xc6 bxc6 1 1 .fXeS i.cS 1 2. lLlf3?!

1 2 . . . ttJgeS!N (The game instead saw 1 2 . . . ttJceS, at which point 1 3.ttJd4!N would have been annoying.) After the text move Black intends . . . ttJd3 and/or . . . .ih6 with full compensation for the pawn.

The above sequence was not forced, but neither side made any notable mistakes, and my feeling is that Black always had enough compensation for the sacrificed pawn. A2) 3 ... lOc6

If White is desperate, he can try a strange and unsound gambit: 4.ttJc3 Wxd4 S .We2 White wants to win tempos with his knights; more natural-looking moves achieve nothing: S .J.e3 Wxd l t 6.!!xd l .ifS 7.ttJbS !!c8 8.ttJf3 a6 is harmless. If S . .id3 then S . . . ttJb4! kills all the fun, especially as 6 . .ibS t wins absolutely nothing after 6 . . . c6. S . . . Wb6!N This is an interesting improvement. The queen is no worse on b6 than the white queen on e2. S . . .ig4 6.f3 id7 looks clever, but after 7.ttJbS Wb6 8 . .ie3 Wast 9 . .id2= Black has to agree to a repetition. 6.ttJdS Wast 7.Wd2 Wxd2t 8 .hd2 cbd8 A minor and temporary inconvenience; the extra pawn is forever. For example: 9.0-0-0 ttJf6 1 O.ic4 J.e6't

4....tg4 Another key move is 4 . . . eS. We shall consider this move in variation B 1 1 on page 244 via the 3.ttJf3 move order.

5.c4?! This is not a great move, but it is useful to see how Black should react. The superior 5 .ie2 will be considered in variation B 1 2 via the move order 3.tLlB .tg4 4 . .te2 tLlc6 5 .d4. White does have another natural-looking move: 5 .tLlc3 The problem with this move is that the early development of the bishop to g4 offers the black queen a new and appealing square: 5 . . . VNh5! Instead 5 . . .VNa5 6.ib5 could take us into territory we don't want to enter. 6.ie2 Also no problem is: 6.ib5 e6 7.ixc6t (even worse is 7.VNd3?! ixB 8.gxB tLlge7+ as in Grushevsky - Korchnoi, Tashkent 1 958.) 7 ... bxc6 8 .VNd3 ixf3 (also interesting is 8 . . . id6!?N 9.tLld2 tLlf6 1 0.tLlde4 ifS 1 1 .tLlxd6t cxd6 1 2.VNg3 0-0 with equality) 9.gxB 1':1:b8 1 0.if4 id6 1 1 .ixd6 cxd6 1 2.0-0-0 tLle7= Janousek - Voj ta, Tatranske Zruby 200 5 . 6 . . . 0-0-0 7.0-0 Black is fine after 7.ie3 e5 8.d5 tLlf6=. 7 . . . tLlf6!

This has been played a number of times.

The acrobatic 5 . . . %Ve4t!? 6.i.e3 i.xf3 7.gxf3 %Vh4 S.d5 0-0-0 9.lLld2 lLld4 is also less convincing than the text move, and leads to complications that require thorough analysis.

6.tLlc3 So far nobody seems to have tried the alternative: 6.i.d2N %Vf5! The position is similar to that reached in line B222 with 3.lLlf3 i.g4 4.i.e2 lLlc6 5.d4 0-0-0 6.c4 %Vf5, but it turns out that Black can achieve more than a simple transposition. 7.i.e2 After 7.i.e3 Black can take the afore mentioned transposltlon with 7 . . . 0-0-0, but 7 . . . e5 and 7 . . . i.xf3 are both more promising. Also 7.i.c3 gives Black a pleasant choice between 7 . . . i.xf3 and 7 . . . 0-0-0 S.d5 e5. 7 . . . i.xf3 s .i.xf3 lLlxd4 9.i.xb7 lLlc2t 9 ...

White protects the d-pawn while at the same time developing a piece. He also remains flexible regarding his c-pawn and queen's knight. They can either contribute to the aggressive set up with c4 and ti)c3 (or sometimes ti)bd2) , or the more solid construction with c3 and ti)bd2. Black has four main responses: B23 1) 6...hf3!? B232) 6... ti)h6, B233) 6... e5 and B234) 6 ... ti)f6.

B23 1) 6 ...hf3!? 7.hf3 Wb5 This rare continuation needs further investigation. Its logic is crystal clear: in return for the two bishops, Black eliminates a defender of d4, makes it harder for the opponent to castle and attacks b2. The idea of . . . ltJxd4 and then . . . e5 or . . . c5 is also in the air. We will follow a fresh practical example.

8.d White seems to have decent compensation for the pawn after: 8.ltJc3!? 'Wxb2 And for that reason Korneev gave it a try two years after his game against Prie. 9.ltJe2 9.ltJa4!? is interesting too: 9 . . . 'Wb5 1 O.ltJc5 (better than 1 0.c3?! e5 1 1 .l'!b l 'Wc4)

This has not been hugely popular, but based on the games available thus far it looks quite promising. Black is developing with no fear of j,xh6 (he would obtain the two bishops and a half-open g-file) and he is ready to intensifY the pressure on d4 by mean of . . . ttJf5 .

7.c4 It is unclear whether White has anything better than this move, for instance: 7.ttJbd2!? ttJf5 (7 . . . e5?! 8.c4 'lWa5 9.d5 proved unpleasant for Black in Izoria - Stopa, Richardson 2007) 8.c4 And now either 8 . . .

7.c3?! e5! is already pleasant for Black. 7.h3?! .ixf3 8 . .ixf3 �b5 can be compared with variation B23 1 with 6 . . . .ixB!? Here Black practically has an extra tempo, as . . . ltJg8-f6 is obviously more useful than h2-h3. 7.c4 �a5t!? 7 ... �h5 8.ltJbd2 transposes to variation B234 1 beginning with 7.ltJbd2. Perhaps the strongest move is 7 . . . �f5! when 8.ltJc3 (8.0-0 e5 9.d5 e4 comes to more or less the same thing) 8 . . . e5 9.d5 e4 reaches line B2342 beginning 7.0-0 �f5 . 8.ltJc3 After 8 . .id2 the reply 8 . . . �f5! is strong. 8 . . . e5 9.d5 .ixf3 1 0 . .ixB This position should be quite playable for Black, although he must avoid the following devilish trap: 1 0 . . . �b4? Instead 1 0 . . . .ic5 or 1O . . . ltJd4 I l .a3 �c5 should be preferred. I l .a3!! �xc4 1 2 . .ie2 �h4 1 3.h3

This time White reinforces the knight on f3, and consequently the pawn on d4, before advancing in the centre.

Chapter 1 2 - 3 . d4 and 3 . lL'l f3 This natural reaction fails to solve Black's opening problems. 8.c4 VNa5 9.d5 .ixf3 9 . . . e4 is no improvement: 1 O.ltJg5! .ixe2 I 1 .VNxe2 ltJe5 1 2.0-0 And White stands much better as the e4-pawn will drop. 1 O . .ixf3 This position was reached in Bruzon Ribeiro, Cienfuegos 1 997.

White can also consider 8 .h3 when the attempt to play creatively with 8 . . . g5?! (better is 8 . . . e5 9.0-0) soon led to a disastrous position for Black after 9.c4 ltJd7 1 0.c5 ltJdb8 l 1 .VNa4±, Gonzales - Antonio, Quezon City 200 1 . 8 . . . e5 9.d5

Conclusion The idea of choosing 3.d4 or 3.llJf3, and then playing for a big centre with d4 and c4, represents a serious alternative to 3.llJc3 . After 3.d4 llJc6 many sharp and interesting lines are possible. However, if Black does not want to bother learning the maze of variations after 3.d4 llJc6 4.lLlf3 .ig4, then 3 . . . eS is a perfectly viable solution. The positions resulting from 4.dxeS %Vxd l t S.c;,f}xd l llJc6 offer him full compensation for a pawn, while White's other fourth moves lead to simplifications in the centre, with a satisfactory game for Black as long as he plays accurately. Since after 3.d4 Black can count on quite reasonable prospects after 3 . . . eS, 3.llJf3 is generally regarded as the best way for White to execute his plan.

273

The response of 3 . . . llJc6 is interesting, although the entire line with 4.llJc3 %VaS S . .ibS .id7 6.d4 0-0-0 7.0-0 was dealt a severe blow in the model game Emms - Kristensen, in which Black was crushed. However, instead of 7 . . . a6, as in the Emms game, there is 7 . . . llJf6 8 . .id2 e6, which may be playable. A more reliable, yet still dynamic, response is 3 . . . .ig4, when play usually continues 4 ..ie2 (we saw that the minor option of 4.llJc3 cannot trouble Black) 4 . . . llJc6 S .d4 0-0-0. In this rich position White has a couple of main tries. The forcing option of 6.c4 %Vf5 7 ..ie3 .ixf3 7 . .ixf3 llJxd4 seems quite okay for Black, according to the current state of theory. White can also opt for the less forcing 6 . .ie3, when there are several options available, most of which lead to rich and dynamic play. I would, however, advise the reader to pay particular attention to the rare 6 . . . llJh6 (line B232) which looks like an effective way to solve his opening problems.

1.e4 d5 2.tLlc3 This move develops a piece while protecting the e4-pawn and attacking dS, and is thus more logical than some of the other "anti Scandinavians" that we will encounter in the final chapter. It is not such a bad line in my estimation, as White keeps some chances of gaining an opening advantage against an insufficiently prepared opponent, or else a balanced yet rich middlegame without having to learn too much theory.

We will analyse two contrasting but equally effective responses: A) 2 dxe4 and B) 2 d4 . The choice between them is a matter of taste, but both are undoubtedly stronger options than the transpositions derived from 2 . . . e6, which comes to a French Defence, 2 . . . c6 a Caro-Kann and 2 . . . tLlf6 an Alekhine. (These are all respectable openings of course, but in each case White has reasonable chances to fight for an opening advantage, whereas the two featured options should both enable Black to equalize comfortably with correct play.) •••

A) 2 dxe4 •••

By exchanging pawns Black relieves the tension while opening some space for active piece play.

3 . . . eS has been a popular choice, but after 4 . .ic4 Black must tread carefully as f7 is rather weak. It is also worth considering: 3 . . . VNdS!? Inviting a return to the Scandinavian, but the knight is not forced to retreat to c3. 4.tLlg3!? This leads to rather unorthodox play. 4.VNf3?! is not to be recommended. 4 . . . tLlc6 S.tLle2 f5! 6.VNhSt? (6.tLlgS tLlf6 was the lesser evil, with only a marginal edge for Black) 6 . . . g6 7.tLl4c3 VNcS 8 .VNh4 eS 9 .d3 f4! Hampering White's development is more important than conceding a stronghold on e4. White quickly went downhill in the duel Kenworthy - Prie, Paris-London 1 994. 4 . . . tLlc6 S.tLlf3 eS!? Rather ambitious. Black can reach a position with a small but manageable disadvantage with: S . . . .ig4

After 7 ..ic4 ttJxf3t S.gxf3 White has a certain lead in development in return for his damaged pawn structure. It is however unsure whether he can draw a substantial profit from it. 7 ..ib2 ttJh6 S . .ic4 �d6 This was Rauber - Prie, Yerevan (01) 1 996, and here White could have obtained a clear plus with: 9.h3!

1 4 .�e2 ttJd5, when the knight enjoys complete stability on its ideal central outpost. The second Caro-type system at Black's disposal is: 3 . . . ttJd7 4 . .ic4!? This tricky move keeps the game lively but all the same balanced. 4.d4 leads nowhere special for White after 4 . . . ttJgf6 5 . .id3 ttJxe4 6 ..ixe4 ttJf6 7 . .if3 c6 with equality.

There are two other notable set-ups for Black, both of which aim to reach an improved version of a Caro-Kann. The first is: 3 . . . .if5 This has been Black's most popular choice in the position. If we continue the analogy with the Caro-Kann variation, the main line will continue as follows: 4.ttJg3 .ig6 5 .h4 h6 6.ttJf3 ttJd7 7.d4 e6 S.h5 .ih7 9 . .id3 .ixd3 1 0.�xd3 ttJgf6

Mter this space-gaining advance the central pawn structure will remain frozen, at least for a few moves. Before analysing the resulting posltlons in detail, I would like to highlight two important themes that we will encounter throughout the following section. The first is the possible undermining of Black's pawn centre by means of c2-c3 and/or tL-f4. The second is the question of how White plans to develop the bishop on fl . In general, he will look to develop this piece actively on c4 or b5. Both sides should be aware that the departure of this piece from the fl -a6 diagonal can often be met strongly by . . . d4-d3.

3.tLlce2 White can also consider the more fanciful: 3.tLlb l After the unusual withdrawal of his knight White will be able to develop his bishop outside the pawn chain on c4. This should enable him to maintain approximate equality, but certainly no more. 3 . . . e5 I have taken a slight liberty with the move order of the present example. The game actually saw 3 . . . tLlc6 here, but in that case

White has the additional option of 4 ..ib5 . 4 . .ic4 1Of6 5.d3 lOc6 6.lOe2 6.lOB would prevent Black's next move but at the cost of blocking the f-pawn, thus slowing down any potential activity linked with its advance. 6 . . . lOa5 Baudson - Prie, Chamalieres 2007. After eliminating one of his opponent's important bishops, Black can look towards the future with confidence. The position may be closed for the moment, but his bishops can still hope for plenty of opportunities to make their presence felt in the future.

This early actlVlty is rather risky. Indeed, White's pieces are lacking space and advancing the f-pawn makes his king feel less safe.

Chapter 1 3 - 2 . tiJ c3 Once again this active move proves to be a strong antidote against White's set-up. The natural 5 . . . i.d6 gives White the opportuni ty for 6.fXe5!

This is the most popular and accurate continuation.

In this, the 1 4th and final chapter, we will discuss all of White's rare options on the second move. These range from the plain weak (2.e5?!) to the timid (2.d3) to the optimistic, with the gambits 2.d4 and even 2.ttJ£3. Without dwelling on the topic, I can already tell you that each of these largely minor lines suffers from certain drawbacks, and in each case Black will have more than one way to achieve a good game. That being said, one should not forget the importance of psychology in chess. Therefore, entering a level endgame after 1 .e4 d5 2.d3 dxe4 3 .dxe4 '?Mxd 1 t 4.@xd 1 might not be the best idea against a player who excels in simplified positions. Likewise, accepting the Blackmar-Diemer Gambit after l .e4 d5 2.d4 dxe4 3.ttJc3 ttJf6 4.£3 ex£3} is almost certainly Black's "best" option, but not necessarily the most appropriate when meeting a tactically skilled opponent.

a French or Caro-Kann. Compared to the French, Black's light-squared bishop will be able to develop actively outside of the e6-d5 pawn chain. And compared with the Caro Kann, the black c-pawn can advance to c5 in one move instead of rwo. (And depending on how the game continues, the bishop might also have the option of moving to g4 rather than the less active f5.)

2 c5 Black can also develop the bishop first with: 2 . . . .if5 3.d4 e6 4.ttJ£3 4.id3 is equally harmless.

Black already enjoys a marked advantage due to his central predominance and the weaknesses in White's queenside, Welz Slobodjan, Bad Wiessee 2002. 4 . . . c5 This position is identical to that reached in one of the main lines of the Advance Caro Kann - except that there the white bishop would stand on e2 instead of f1 ! Readers who are interested in investigating such positions in greater detail are advised to consult Chapter 1 2 of Lars SchandorfFs Grandmaster Repertoire 7 The Caro-Kann. -

Chapter 1 4 - 2nd Move Sidelines 5 .i.e3 White is not ready for 5.c4 dxc4 6.i.xc4 ttJc6, whereas 5.c3 would restrict him to a defensive role, and Black is extremely comfortable after 5 . . . lLIc6 intending . . . lLIge7. 5 . . .

Black will regain the sacrificed piece while keeping a superior position. His king is quite safe, and he enjoys a solid grip on the centre. The immediate plan will be to unravel the kingside pieces by means of . . . e6-e5 followed by . . . e7 -e6. Meanwhile it is not so easy to suggest a worthwhile plan for White.

2 ... e5!? reaches a kind of reversed Centre Game in which the extra move d2-d3 actually helps Black, as the natural 3.exd5 Wfxd5 4.lLlc3 can now be met by 4 . . . .ib4!, avoiding losing time with the queen. The position holds chances for both sides. 2 . . . lLlf6 is also perfectly valid. (Interestingly, according to the database this has been played less than 30 times after 1 .e4 d5 2.d3, yet the position after 2 . . . lLlf6 has occurred in over 700 games in total! The explanation is of course that the majority of those encounters began via an Alekhine move order.) Play may continue: 3.e5 lLlfd7 4.f4!? (4.d4 c5 5 . c3 lLlc6 is also possible, with an unusual type of French.) 4 ... c5 5 . .ie2 lLlc6 6.lLlf3 e6 Now if White tries to reach a French-type position with 7.c3 .ie7 8.d4, he may have trouble developing his queenside pieces after 8 . . .

3.dxe4 Wfxdl t 4.�xdl e5 This endgame, or rather queen less middlegame, is completely level. The fact that White has lost the right to castle does not change anything since his king will find a safe haven on c2. Of course, an equal position does not guarantee a draw, and a strong technician might very well try to win from either side of the board.

2nd Move Sidelines

This gambit is dubious and unfounded. One way to look at it would be as a Budapest Gambit with reversed colours, except that Black's c-pawn is on c7 instead of c5, which might even benefit him in certain lines. Overall the most White can realistically hope for is to regain his pawn and equalize; and he might not even manage to achieve that, as we will soon see.

2 ... dxe4 2 . . . e6 and 2 . . . c6 would only transpose to sub-variations of the French Defence and Caro-Kann respectively. Black already has to show more ambition!

If Black is content to return the pawn, the simple 3 . . . e5!? deserves attention, intending to meet 4.lL\xe4 with 4 . . . f5! followed by . . . .te6. The optimal development of the enemy bishop to c4 is prohibited, leaving Black with the better chances thanks to his space advantage and central control.

4.g4!? This energetic though weakening thrust may well be the least of the evils, at least as a practical try to muddy the water. Indeed, White experiences the worst difficulties after the "normal" follow-ups: 4 . .tc4? achieves nothing after 4 . . . e6, when Black also wins an important tempo due to the attack on the g5-knight.

3 .t5 ! The other automatic way of protecting the pawn, namely 3 . . . lL\f6?!, would let the advantage slip. After 4 . .tc4 Black is compelled to obstruct the diagonal of his light-squared bishop. The position resulting from 4 . . . e6 5 .lL\c3 .te7 6.0-0 0-0 7.lL\gxe4 would then be reminiscent of a French Rubinstein (reached after the opening moves l .e4 e6 2.d4 d5 3.lL\c3 [or lL\d2] 3 . . . dxe4 4.lL\xe4) . Black is certainly not in any danger, but nor is he better. •••

e5!? It is well known that the acceptance of the gambit pawn leads to a position where White's compensation is technically inadequate. However, my personal view is that the practical risks of going astray while trying to neutralize the white initiative are pretty high. Nevertheless, if the reader is determined to try and refute the gambit, I will offer a brief outline of one of Black's better defensive systems, based on the repertoire presented in Lars SchandorfFs Grandmaster Repertoire 7 lhe Caro-Kann. 3 . . . lLlf6 4.B exB 4 . . .i.f5 is sometimes played, but after 5 . fxe4 lLlxe4 6.�B lLld6 7.i.f4 e6 8 .0-0-0 White is becoming quite active. 5 .lLlxB c6 6.i.c4 6.i.d3 is well met by 6 . . . i.g4. 6 . . .i.f5 7.lLle5 After the quieter 7.0-0 e6 8.lLle5 i.g6 9.i.g5 lLlbd7 White has very little to show for the pawn. 7 . . . e6 8 .g4 3

The text move is not an attempt to refute the gambit, but rather to draw the opponent away from his comfort wne. White can choose between four main approaches: taking the pawn with 01) 4.dxe5, developing with 02) 4.lLlge2, starting an attack with D3) 4.Wlh 5 , and finally the main line of 04) 4.lLlxe4. Alternatives are clearly worse, for instance: 4.dS?! Relieving the central tension enables Black to choose between a few tempting continuations. Here is one of them: 4 . . . c6! ? Pinning the knight by 4 . . . .ib4 i s a good alternative. S .WlhS!? This seems like a principled move, but the complications turn out favourably for Black. S . . . cxdS 6.WlxeSt .ie6 7.lLlbS lLlc6! 8.Wlg3

Or 8.lLlc7t @d7 9.lLlxe6 lLlxeS 1 0.lLlxd8 �xd8 with a sound extra pawn. 8 . . . �c8 9 . .if4 lLlf6 1 0.lLlc7t No better is 1 O.lLld6t .ixd6 1 1 ..ixd6 lLld4. 10 ... @d7 I l .lLlxe6 fxe6 White is a pawn down with a worse position. The black king is safely hidden, but the opportunities to activate his army are teeming, with . . . lLld4 (or . . . lLlb4) , . . . Wlb6, and . . . lLlhS all looking rather troublesome for White. 4 . .ie3?! White develops a piece while simultaneously reinforcing the attacked pawn. This move is, however, less j udicious than 4.lLlge2. 4 . . . exd4 S .Wlxd4 This gives better equalizing chances than: S . .ixd4 lLlc6 (S . . . lLlf6!?) 6 . .ibS .id7 7.lLlge2 Wlh4! The queen's outing on h4 fulfils several functions. It exerts pressure against the enemy kings ide, defends the e4 pawn and prepares long castling. This last factor is particularly important because of the impending vis-a vis between the queen on d l and rook that is about to land on d8. 8 . .ic4 (8.lLldS 0-0-0 9 . .ixc6 Lc6 is no better) 8 . . . 0-0-0! 9 . .ixf7 .ig4

6.lDc3! This somewhat humiliating move is the only way for White to maintain the balance. After j ust six moves Black has taken over the 'advantage of the first move' , but despite this moral victory, he is unable to secure any meaningful advantage. By contrast, the inaccurate 6.f4?! leaves White with a weak isolated pawn. Here is one practical example: 6 . . . exf3 7.lDxf3 �g4 8 .�b5 lDge7 9.lDe3 �xf3 1 O.gxf3 a6 1 1 .�xc6t lDxc6 1 2.f4 0-0-0 1 3 .�d2 �c5 1 4.lDf5 g6 1 5 .lDg3 �f2t 1 6. i>e2 �xg3 1 7.hxg3 lDd4 t 1 8 . i>f2 lDxc2 And Black went on to convert his extra pawn in Zauner - Maljutin, Werfen 1 992.

This has been the highest-scoring of White's main options, but that does not mean we should fear it.

With 4 . . . tDf6!? 5 .%Vxe5t j,e7 Black tries to turn the tables with a pawn sacrifice of his own. He certainly obtains promising compensation after 6.tDxe4?! 0-0, but a better idea for White is 6.j,f4 c6 7.%Vc7!? with interesting play.

5.dxe5 5.d5? tDf6 and 5 .j,b5 ? exd4 are unacceptable for White. 5 ...j,b4 6.j,d2 g6 Black cannot do without this move indefinitely.

Conclusion None of the four options examined here should be ofgreat concern to Scandinavian players. The only one that requires any serious consideration from Black is line 0, the Blackmar-Diemer Gambit with 2.d4. After the usual 2 . . . dxe4 3.llJc3, for reasons explained earlier, I find declining the gambit with 3 . . . e5!? to be quite an attractive course of action for Black. White can shift gears and head for the equal ending arising after 4.dxe5 Wfxd I t 5 .llJxd l , but who would be willing to start a game this way as White? On the other hand, we saw that after the aggressive 4.Wfh5 Black is also doing well when the game takes a tactical turn. It seems that line 04 with 4.llJxe4 represents the first player's only chance to maintain the balance. In this case he will have reasonable chances to regain his pawn to reach an equal position, but will have to kiss goodbye to any chances of launching a deadly sacrificial attack.
