Introduction The Sicilian Sveshnikov is one of the most popular defences ίη contemporary chess practice. Its theory is developing rapidly. Since the ,publication of Sveshnikov's book The Siciliαn Pelikαn, many hundreds of games have been played, greatly enriching the theory of this variation. Our book is about these games and the conclusions ιο be drawn from them. Before sending the reader forth through the labyrinth of the many variations of this system, we would like ιο talk about the common thread ίη them. Ί\vo factors appear ιο be fundamental ιο the system: Black's gaping hole οη d5 and White's slight lack of development. Ιι is ηο joke to say that the white g l-knight makes four ΟΓ five moves at the very outset - as if the knight has promised his queen he wi11 make as many moves as possible, and is ηοι allowed Ιο do otherwise. Thus the main battle takes shape. Which, then, is stronger: White's static SUΡeήοήtΥ ΟΓ Black's dynamic advantages? This controversy has been going οη for a 10ng time ίη chess history.

Tarrasch was clearly ίη favour of White. His opponent was the great chess player and philosopher Lasker. His use of what was ιο later become known as the Pelikan Sicilian stemmed from his deep understanding of chess strategy. This is what B.Weinstein, the author of The Thinker, the bri11iant work οη the second World Champion, said of the conflict: "Pressure οη weak points! Doesn't that remind you of stress testing under a heavy 10ad? Testing ιο destruction! Βυι if the construction is solid ίι wi11 resist, and the attack wi11 fail". Another route - the dynamic one - is also possible; gather a11 one's forces ίη the decisive area (even at the cost of weaknesses ίη other places) and then inflict a blow, acting quickly and energetica11y, so that the opposition cannot make use of these weaknesses. Thus, Lasker's strategy was based effectively οη ideas which were much more wide-ranging and fruitful than the basic ΡήηcίΡΙes of pressure οη weak points, ideas of superior mobility, space and ammunition, and an advantage ίη strength.

6 Introduction

Ιι has long been well known that the basic strategy ίη chess lίes ίη the struggle ΙΟ control the key squares, and, ίη the first place, the central squares. as the pieces which are arranged οη them are the most active. And although ίη the course οί the game the objectives οί attack might change more than once, the fight for the e4-, d4-, e5- and d5squares carrίes οη practically permanently. Το show the reader graphically the essence οί the conflict, we have chosen a basically old game, and ίη the years that have passed since the game was first played. the theoretical assessments ofindividual νarί­ ations have changed, butthe ideas have remained. The game which you will now examine has been commented οη more than once, but previously ηοΙ all the evaluations have seemed justified Ιο us. So, the reader will judge who is right.

Isn't ίι strange that this is one οί the most popuIar continuations οί the Sicilίan Defence? What attracts

W Black Ιο leaving d5 so weak? The fact is that from the very first moves the conflicts οί the position are heightened. and both sides face difficult strategic problems. Indeed the move ... e5 has clear positional advantages: the d4-knight is driven from its central position, and White has less freedom οί movement ίη the centre. and οη the kingside.

Introduction 7 This move prepares lίk2 followed by a4. The battle for d5 is already ίη full swing: ηο sooner is the f6-knight removed, than White tήes Ιο eliminate the b5-pawn and give the light-squared bishop an active position οη c4. The most pressing problems for Black are Ιο finish his development, and find better squares for his pieces, especially his bishops ( ... ~g5, ... ~e6), and thanks Ιο his e5-pawn he need ηοΙ fear an assault by the white pawns. 11 ... ο-ο 12 lbc2 :b8 Directed against a4. 13 ~e2 ~g5 14 ο-ο ~e6 (D)

the b5-pawn prevents the enemy bishop from landing οη c4, and when the opportunity aήses, ...a5 is possible, stopping lbc2-b4). After Black has dealt a blow Ιο the e4 pawn with ... f5, the white centre turns ουΙ Ιο be suποuηded from the flanks. 15 'iVd3 Prepaήng a place for a rook (which one depends οη the circumstances) οη dl Ιο support the central knight. This means that Black must distract ίι with other problems. Threats along the f-file, created by doubling rooks, serve this aim well. Such is the strategic outlίne of the battle, and moreover the d5-square itself can be practically ignored by Black, with his pieces more or less flowing round ίι Ιι remains for the game to be shaped definitely.

Besides, 15 ...:b7 frees b8 for the knight, e.g. 16lΔcb4lΔb8!? with the idea of ...lDd7-c5 and then ...f5 (although the simple 16 ... lΔxM is also reasonable). 15 "iWd7 Α quite acceptable decision, although it seems less significant than 15••':b7. 16 'ifg3 Here the queen does not get ίη the way of her own pieces, and meanwhile is not susceptible to any attack. Besides, she is attacking the opposition's dark-squared bishop, which is placed οη an important diagonal (exerting control over e3!). 16•..J.h6 is impossible here because of 17 lΔf6+. 16 Ι6!? (D) Black is seeking the possibility of leaving his bishop οη the cl-h6 diagonal, insofar as his next move

17 ... J.h6 followed by ... f6-f5 is still possible. Βυι 16••...td8 doesn't 100k bad either (from this position the bishop aims at both flanks). 16••• h6 is worse, as weakening g6 makes play Iinked with carrying out ... f7-f5 more difficult.

W 17 :fd1 a5? Why ηοΙ 17•••J.h6? Maybe Dolmatov, when he played his 16th move, calculated the following varίation: 18lΔcb4lΔxb4 19lΔxM

a5 20 lΔa6 :c8 (20...:b6 21lDc5) 21 'it'd3 J.c4 22 'ifxd6 'ii"xd6, and then, having discovered the intervening check 23 J.xc4+, avoided this line. Ιη νώη! ΒΥ continuing 23 ...:xc4 24 :xd6 :xe4, we can see that only White will have difficulties. If instead of 20 lΔa6 he had chosen 20 lΔd5. then after 20 ... f5 Black has good counterplay (as we will see later on, such a correlaιίοη of the Iight pieces, that is two

After two precise moves the fol10wing part of the game takes 00 a technical character for Karpov. White's plan coosists of the fol10wing elements: 1) exchanging the lesser pieces (light-squared bishop and knight); 2) opeoiog a file 00 the queeoside and invadiog with the knight ίηΙο the enemy camp; 3) prepariog aod carrying ουΙ ao attack agaiost the king. How can Black defeod himself? Passive defeoce will spell his doom quickest of all. Therefore he must

use aoy possibility ιο change the character of the struggle, for example, at this ροίοι a pawo sacήfice was possible: 19•••g6 20 ..tg4 f5 21 ..txf5 (ίη the eveot of 21 ef gf and 22 ..te2 then 22 ... 'ilg7 with the idea of 23 ... f4, aod if 22 ..txf5 then 22 ... 1Σχf5 23lDe3 'ilg7 with a double-edged game) 21 ... gf22 'ilxg5+ Φh8 with some compeosatioo. Dolmatov missed this possibility. 19 ••• Φh8 20 ..tg4 1Σfc8 20•••g6 is better. 'ilxe6 21 ..txe6 1ΣcS? 22 'ifd3 Now the rook cannot help defeod his king. From now 00 Karpov virtuously prevents all his attempts Ιο get ίοΙο the game. 22•••g6 would have been more persisteot. 23 lDc2 g6 24 b4! ab 25 lDcxb4 It is instructive Ιο observe the realization of ao advaotage. Here White also had at his disposal the continuatioo 25 cb with the idea after a2-a4 of gaioiog an 'extra' passed pawn. Βυι this opens the cfile, which Black controls at the momeot. However, ίι does οοΙ give the oppositioo aoy couoterplay; one must open precisely the file which can be seized. 1Σb7 25 26 a4! ba

Of course, although the above game is typical, ίι far from exhausts all of the many clashes of strategic ideas brought ουΙ by players of the Sveshnikov. We should add that this system wages war οη all new adherents. It forms part of the permanent opening reperιoire of Grandmasters Alexei

Shirov, Vladimir Κramnik, John Chandler, Ketevan Arakhamia as well as many other prominent and rank and file chessplayers. Ιη the book we will examine 31 main and hundreds of subsidiary games. Insofar as the move order ίη the Sveshnikov can be either 1 e4 c5 2lbf3lbc6 3 d4 cd 4lbxd4lbf6 5lbc3 e5 6lbb5 d67 .i.g5, or 1 e4 c5 2lbf3 e6 3 d4 cd 4 lbxd4 lbf6 5 lbc3 lbc6 6 lbb5 d6 7 .i.f4 e5 8 .i.g5, then the move numbers ίη both the main game and the subsidiary games are taken from the first move order given above.

this system White actively fights for control οί d5. He gives υρ his light-squared bishop ίη retum for his opponent's knight and fights Ιο ρυι his own knight οη d5. Ιη the event of an exchange White is prepared Ιο replace ίι with other pieces. Black's counterplay is most often linked with the thematic move ... f7-f5 and activity οη the kingside and ίη the centre. Β

16 :xb7!! thunderbolt from a clear sky! Played ίη the style of Nimzowitsch, Petrosian, and indeed of Α

Kasparov himself, this represents a typical positional exchange sacrifice. White does ηοΙ gain any kίnd of profit immediately, a1though the strategic superiority of his posiιίοη more than makes υρ for the materialloss. What advantages are ίη question? Ιη the first place, Black has lost his Iίght-squared bishop, which would have played a large role ίη organizing a counterattack. As a consequence of this, the role of the blockading d5knight has grown, and, as ίι has ηο opponents, ίι is more powerful than the rook. Moreover, Black's lίght-squared bishop was ίη full control of his teπίtοry. Secondly, the black knight is now (and, as ίι tums ουΙ, υηΙil the end of the game) excluded from play. Thus ίι is υη­ clear whether this is an exchange sacrifice or winning two pieces for arook. So, White's plans have become obvious, but ίι was ηοι easy ιο come ΙΟ this paradoxical solution. The abilίty ιο find such obscure ideas marks ουΙ the outstanding players from the merely good ones.

1/"_1/,, Conclusion the games ίη this first chapter, White's hopes are linked with play οη the queenside (ίη many cases this is accounted for by the fact that Black does ηοΙ hinder a2-a4) and ίη the centre. Black prepares an assault οη the kingside. But ίη general this means that play is spread over the whole board. As we can see, the engagement turns ίηΙο a full-blooded battle, and he who is the more inventive and resourceful will be the victor. Ιη

2 9...~e710 .txf6; 12....:ϊb8 Quite often Black does ηοΙ allow his opponent Ιο play the automatic a2-a4 so easily, by adopting the precautionary ... .:ta8~b8. Ιη this case White must devote more attention Ιο the centre and kingside. Ιη a tense battle Black's chances aren't Ιοο bad (as Black's chances go). The light-squared bishop does ηοΙ play its previous role (as ίη Game 3, for instance), which often tums ουΙ better for his opponent. Kamsky demonstrates this plan by exchanging this bishop even at the price of apparently strengthening Black's pawn cenιre. The Αmeήcan Grandmaster's play is more profound, ηοΙ using the particular weakness of d5, but of the pawn centre as a whole. Game5 Lputian Biel ΙΖ 1993

this chapter we will begin to examine the whole stratum of νari­ ations beginning with 9 ~xf6. With this moνe White actively starts the fight for d5, and moreoνer doubles Black's pawns. However, ίη return Black gains the bishop pair and the open g-file. Even his doubled pawns actiνely influence the centre. As a rule, this preordains an extremely complex strategic and tactical battle oνer the whole of the board. Game 11 Dolmatov - Topalov Groningen 1993 1 e4 c5 2lbf3 ~ 3 d4 cd 4lbxd4 lbf6 5 lbc3 e5 6 lbdb5 d6 7 ~g5 a6 8 lba3 b5 9 ~xf6 gf 10 lbd5

is always quite teπίfΥίηg, especially when the white king is sheltering οη the queenside, and ίη reply to ... b5-b4, White must strike οη b4, opening the way for the dpawn.

Β Ιη Sveshnikov ρositions with doubled f-pawns, White sooneror later runs ίηto the problem οί the c-pawn. Indeed the knight οη a3 most frequently enters the struggle via c2. Therefore a choice arίses as ιο whether Ιο move the c-pawn one square or two. c2-c3 looks slίghtly more solίd. Ιη the event οί c2-c4 White is gaίning time, but it also has an essential disadvantage: exchanging the more central c-pawn for its black colleague οη the b-file ίη many cases opens the way for the black infantryman οη d6.

W Arriving ίη the world chess elite, Grandmaster Vladimir Kramnik is an ardent admirer ofthe Sveshnikov, aπd because of this, one can judge the development of the system as a whole from the variations he chooses to use. Kramnik has introduced many new ideas, often

(Typesetter's note: It ίδ worth mentioning that 14...e4 is bad after 15 ~e7 'ifxe7 16 J.xb5+ axb5 17 'ifd5 and White wins a pawn.) 15 J.xf5 ~e7 15...~f6 is ηοι proιnising, as it allows White to consolidate conclusively his hold οη f5, which has ηο less (if ηοΙ more) significance than d5, as it ίδ closer Ιο the enemy kίng.

Before this game White usually reacted to Black's transpositίon (13 ... ~e7 instead of 13 ...J.e6) by means of the standard 14 lLJce3, which led to a normal poδίtίoη from this varίatίon: 14...J.e6 15 g3 ~xd5 16 ~xd5 ο-ο 17 J.g2. Of course, this narrows down his possibilίtίes. After 13 ...J.e6 White can for the tίme being manage without 14 ~3 and straίght away develop his kίngside with g2-g3 and J.f1g2.

Conclusion Ιη this chapter we have examined games from one of the most aggressive variations of the Sveshnikov. If White plays 12 "h5, a very sharp game arises, giving ήse ΙΟ reasonable counterchances for Black.

However, the plan 1inked with 12 ...:g8 seems more promising. After 12... f4 and 13 ...~g7 he often falls ίηΙο a difficult position. The game goes οη ίη a more positional mood after 12 ο-ο with a small advantage (as, strictly speaking, is predetermined) Ιο Whiιe.

9 Classical Sveshnikov: 11 iιxb5 Nowadays it is quite rare to see White sacrificing a piece οη b5 οη move 11. Moreover, if the knight sacήfice has gone completely out of use, then taking with the bishop is wrong, as this scene shows ...

speaking, play ίη this νaή­ ation begins οηlΥ οη move 11, because White most frequently plays ίι with a transposition of moves: 9 lbd5 iLe7 10 .i.xf6 .i.xf6 Illbbl.

this situation there are two ΡήηcίΡaΙΙΥ different possibilities. With 8 ... J.e6, Black tries Ιο bring his pieces ίηΙο the battle quickly: ... %:tc8, ... lbd4, creating pressure 00 the c-file. Alternative cootinuations:

a) Black has tried by the mechanical means of 8••• h6 Ιο hinder a ρίη οη the knight, but after 9 iιc4 iιe6 10 ο-ο %:tc8 11 %:tellbb4 12 b3 iιe7 13 .ib2 ο-ο 14 'iWe2 'ii'c7 15 h3 %:tfe8 16 %:tad 1 'ii'c5 17 %:td2 Φh7 18 %:ted 1 (Radulov-Neckaf, Vratsa 1975) White firmly seized the ίο­ itiative. b) 8....ie7 solves the problem of developing the kίngside. b1) Ιι would seem that Black then also makes 9 .igS difficult, although after 9 ...lbxe4 1Ο lbxe4 (10 .ixe7lbxc3 11 .ixd8lbxdl =) 10... .ixg5 Illbxd6+ ~e7 12&4 .ie6 13 'iWf3! lbd4 14 'iWxb7+ 'i/ί'd7 15 'iWxd7+ (15 'i/ί'e4 f5 16 'i/ί'd3 .if6 with the initiative ίη return for the sacrificed pawn) 15 ...

Nevertheless, one of the key ρο­ sitions of the entire variatίon has arisen, and understanding ίι is very important for playing simίlar positions, which as a whole are typical of the Sveshnikov. After 14•••lDe7 15 _b3 ~xd5 (15 ...lDxd516edand 17_xb7) 16 ~xdS lDxdS 171!fxdS 1!fc7 18 :fdl :fd8 19 lDc2 an ideal cοπelatίοn of pieces, with possession of dS, arises for White, which gives him a big advantage; furthermore, Black is forced ιο watch passively as Whiιe reinforces, and counterplay with ... f5 is at this Ροίηι Ιοο laιe.

Clearly Black should avoid such positions by every means possible.

15 ~B2 If 15 'ife2, then 15•••~b8!? is not bad, with the plan of transferήng the knight to c5, whilst also keeping an eye οη the a4-pawn and preparing ... f5. Recently thίs manoeuvre ίη the Sicilίan Defence (the Boleslavsky System, for ίη­ stance) has become very popular, and is longer called into doubt (for losing time?), as moving the knίght Ιο c5 and ΡressuήΖίng e4 is Ιοο good an idea. Οη the other hand, 15•••~e7 scarcely allows Black Ιο hope for equality after 16 ~xe7 'ifxe7 17 1ΣadΙ 1Σfd8 (the moves ...

Here, 15•••~b8 is ηο good because of 16 ~c4, but the continuation ίη the game is quite sufficient for equalίty, as the bishop οη a2 is not best placed. In general Black has to follow the nuances constantly, and, depending οη White's continuation, vary his game. For example, why exactly did Black play 14...Φh8? Evidently to prepare ... f5. But the time for this plan has not yet arrived, ίη that 15••.f5 is met by 16 ~b6! gaίnίng mateήal. It is possible that this blow will not be carried out, but it does not mean that we should hurry to condemn the king move as an eποr. The threat was created all the same, and White was forced to deal with it somehow. True, alongside 14 ... Φh8, 14•••~b8, with the idea of bήngίng the knight to c5, deserved attention.

Conclusion The move 7 a4 does ηοι cause Black any special trouble; thanks ιο the extra tempo he has good development and a large choice of plans, and he simply does ηοι need to force events ( ...ιt1f6xe4 is very often premature and fails to equalise). But adherents of quiet positional play (whilst indeed many variatίons ίη the Sveshnikov are quite sharp) can boldly be advised to play ίι as White; the precautίon­ ary move a2-a4 deprives Black of his actίvity οη the queenside ( ...b7b5), and if he succeeds ίη holding onto d5 with little 10ss of blood, then he can expect a definite advantage.

14 White plays 6 ~f5 Ιη this final chapter we will examine a deviation for White from the maίn vaήatίοn ίη the very early stages of the battle. 6 lLIf5 is the one that deserves most attention.
