Introduction After reading the title of our book you haνe the right Ιο ask the question: '00 the authors consider the Grίinfeld Defence ΙΟ be a winning one?' Well, of course that is ηοΙ the case. Anyone with half an eye can see that there are ηο directly winning openings either for Black or eνen for White. Rather the titIe of our νolume hints at a method: play and do "ot bury your head ίη the sand! There are openings - for example the Queen's Gambit, the Queen's Indian Defence or the Caro-Kann Defence - ίη which, during the first stage of the game, Black adopts a defensiνe, though stable, position. His first intention is ιο exploit eνen White's smallest mistakes to reach equality and οηlΥ during later stages of the game - the middlegame or endgame - does he aim for an adνantage. That demands, of course, further mistakes οη White's part. Ιη the case of the Grίinfeld the shoe is οη the other foot. From the outset Black increases the tension, deνelops an asymmetrical position Hnd permits White ιο build υρ a strong pawn centre, while he prepares to undermine this centre and start a counterattack ίη good time. Instead of strictly theoretical equality, ίη the Grίinfeld Defence a dynamic equilibrium arises ίη which opponents haνe ιο recognise the fundamentals and peculiarities of the position and elaborate and execute their plans accordingly. Necessarily ίη situations of this nature there are more chances of making mistakes, and therefore more chances of a decisiνe game. We intend this book mainly for practical players. For that νery reason we did ηοΙ write a co.mplete encyclopaedic νolume; instead we offer you a repertoire, enabling you ιο counter any of White's principa:l continuations. This repertoire was played with success ίη top-class tournaments by one of the authors, ΙΟΜ Adorjan, for nearly two decades. Since then Adorjan has been interested ίη other areas Ιοο, but he has stuck firmly to the lines giνen ίη this book. (Mistakes, of course,

2 lntroduction are possible, but bamboozIing, mystification and seIling incorrect sacrifices with the help of showy variations is ηοΙ ίη my nature - Α.Α.) The two main consequences of this treatment are: 1) Against each White set-up there is aIways οηΙΥ one variation for BIack, but that one is analysed ίη detail, Ιο the best of our knowledge. For example, against the Russian System (Chapter 2) there are many good defensive methods for Black, but we will discuss οηΙΥ the Hungarian System, which we consider Ιο be the best. 2) There are anaIogies and relationships between the recommended answers and set-ups given Ιο White's different attempts. For instance, there are severaI systems ίη which White drives away Black's knight from d5 and the seCond pIayer has the choice between exchanging οη c3 and retreating Ιο b6. According Ιο current opening theory both continuations are of equal viability. We will, however, deal with the exchange οη c3 οη all occasions, consequently aiming at positions of a similar type. Our selection of material is based οη the original classical GrϋnfeΙd idea, ίη whatever system is discussed. Thus we will always proceed with Iines that seek counterpIay with ... c5, despite the fact that set-ups with ... c6 and ... d5 have often been played recently. There is only one exception Ιο this rule: the set-up with ... c6 and ... d5 ίη Chapter 7, but there we again avoid the knight retreat Ιο b6, using the c-pawn Ιο capture οη d5. We recommend our readers Ιο play actively, Ιο try Ιο seize the initiative even at the price of a pseudo or, ίη many instances, real pawn sacrifice. The basis for the selection of illustrative games is as follows. The games· show the lίnes considered by us Ιο be best. Besides games played ίη the latest tournaments which demonstrate new ideas and innovations, we have selected games regarded as classical stem-games of some variations. So we give ίη fully analysed form games which are also quoted ίη other theoretical works as definitive for a variation but represented there οηlΥ by a couple of moves. Their middlegames are tyJjical, characteristic of the variations given and demonstrating standard motifs. That is why we do notjudge a Black win Ιο be an absolute requirement, and why we inc!ude, besides several drawn games, encounters lost by Black. Our illustrative games meet at least one of these requirements. Ιη analysing games we have emphasised, of course, the opening, but we have also tried Ιο indicate the correct continuations ίη the

Introduction· 3 complications of both middlegames and endings. This book contains many preνiously unpublished games. This fact is pointed ουΙ οηlΥ ίη the case of the most important games, but you can find such games ίη eνery chapter. Ιη many instances we draw your attention Ιο moνes which can be played ίη reνerse order, and we illustrate transpositional possibilίties which are important knowledge for practical players. We intend this book for actiνe players who pIay for a wiD. Our firm conviction is that the second pIayer shouId ηοΙ set himseIf the target of haIf a ροίηι! The GrϋηfeΙd Defence is an exceIlent means of realizing more ambitious objectives. We hope that whiIe reading this book you enjoy discovering further finesses ίη the GrtinfeId and that you will be abIe Ιο empIoy your new knowledge successfully ίη your future tournaments.

White's first and most natural reaction is acceptance of Black's intention by 4 cd ~xd5 5 e4 ~xc3 6 bc occupying the centre. Τhis is the starting position of the Exchange Variation and of the material Ιο he discussed ίη this chapter.

According Ιο classical principles, White should stand better. Τhis eνaluation was particularly considered a well-founded one at the time of the appearance of the opening. (Ιι was first played by the late Austrian grandmaster Grϋnfeld ίη 1922 and hence is named after him.) Ιι was the elaboration of this νery opening, among other things, which resulted ίη the reνision of classical principles. It was proνed that occupying the centre with pawns does ηοΙ necessarίly lead ιο an adνantage. Τhe essential thing is Ιο haνe control oνer the central squares. (Similar ideas can be seen ίη the Alekhine Defence, the Reti Opening and the Nimzowitsch Defence.) Ιη the present instance Black is prepared ιο fight against White's centre. Τhe counterplay can be started by ... j.g7, ... c5 and ... ltJc6. Ιη the Exchange Variation White can choose between two main

6 Exchange Variation lίnes.

One is 7 .tc4 followed by lLIe2, elίminating the ρίη which wouId be possibIe after 7 lLIf3 .tg4. This deveIopment was thought for a Iong time Ιο be White's best pIay. Former worId champion Boris Spassky, for exampIe, gained some memorabIe victories with this setυρ, twice defeating, among others, Fischer. Later, theory improved BIack's pIay and demonstrated sufficient counterpIay for the second pIayer. The move 7 lLIf3 was formerIy rejected because ίι was thought that the ρίη 7 ... .tg4 wouId heIp BIack ιο attack the centre successfully. Αι the end of the 1970s, however, this move was brought back from negIect. It appeared that ίη the event of ... .txf3 the recapture gf couId be good for White ίη many instances since ίι further strengthens his pawn centre. White's fans found brand new ideas too, which were frequently connected with pawn or exchange sacrifices. The variation with 7 lLIf3 became even more popular after Kasparov gained severaI spectacular victories with ίι. It took supporters of the BIack side a Iong time Ιο recover their wits and discover the proper defence. Ιη the last anaIysis, we can say that 7 lLIf3 is ηοΙ stronger than the earlίer continuations.

12 1Wd2 This queen move came ίηΙο fashion ίη the early 1970s. Ιι was mainIy played with success by Vaganian. White intends ιο develop a kingside attack by j.h6 and, after exchanging bishops, f4.

Besides achieving quick development, White has another idea. After strengthening the centre, or possibly even immediately, he wants to play llcl to prevent ... c5 and also Ιο exercise pressure along the c-file. Οη the natural 4 ... .tg7 White has two basic plans.

One is Ιο secure the centre with 5 e3, when Black's most frequent answer is 5 ... ο-ο. White can now choose between four moves: a) 6 cd lbxd5 7 lbxd5 1!fxd5 8 .txc7, with an extra pawn. b) 6 lbf3 c5 7 dc ιt::\e4!. c) 6 't!rb3 c5 7 dc lbe4!. d) 6 1icl c5 7 dc .te6. We will analyse 5 ... c5!? (instead of 5 ... 0-0), which has become increasingly popular recently. With this move Black avoids the a), b) and c) lines and limits White's possibilities. However, after 6 ιt::\f3 ο-ο, variation b) can arise from another Inove order. This continuation will be considered ίn the games Ribli-Timman and YuneyevPolovodin. Consequently, after 5 ... c5!?, it is 6 dc which has independent significance. This line wilI be analysed ίη the games BohmTimman, Petrosian-Fischer and Schmidt-Gross.

Systems with J,{4 55 White's other option is ιο delay e3 and play 5 lbf3 immediately, followed by 1ΣcΙ. Ιπ this line the f4 bishop is πο! shut off from the queenside by the pawn οπ e3 and this factor is sometimes advantageous for White (see FeuersteinSimagin and Andersson-Sax). Ιπ systems with i.f4 White cannot prevent Black's ... c5 counterplay. The exchange of centre pawns opens the position υρ and the play becomes sharper. The system with i.f4 was often played by the world champions Capablanca and Petrosian, while Botvinnik did pioneer work ίη the elaboration of Black's defensive resources. Black's play has been enriched by contemporary grandmasters too, ίη particular Timman, Tukmakov, Tseshkovsky and the Hungarians Ribli, Adorjan and Sax. Gamel6 Bohm-Timman

White can also fight for an advantage ίη the centre with 4 .tg5, attacking indirectly the d5 square. Ιη this case both 4 ... dc and 4 ... c6 are insufficient for Black. This variation was first seen ίη Αlekhίηe-Grϋnfeld, Vienna 1922, when the eponymous player of the black pieces answered with the powerful 4 ... lbe4!. Later ίι was proved that both the exchange of knights and the retreat of the bishop Ιο [4 leaνe Black with an edge or, at least, easy equality. These factors almost ρυι this variation ουΙ of business ίη top-class pIay for a Iong time. The decisive year was 1969, when Taimanov, the great innovator, first played 5 .th4! (TaimanovSavon, USSR Ch), resurrecting the variation. After the initial surprise the defence was more thoroughly examinedand methods of achieving equalίty were worked out.

The Quiet System

Against the GrϋηfeΙd Defence, White often chooses the following plan: before developing the fl bishop he strengthens his centre with e3 and aims to seize an initiative by swift action οη the queenside. Ιη this case, of course, he renounces any claim to an advantage ίη the centre. We recommend this variation to players who like quiet manoeuvring play. The basic position arises via 1 d4 ~Ι6 2 c4 g6 3 ~c3 dS 4 ~o j"g7 S e3. Black can now choose between two basic plans. One is to play 5 ... c6 and after completing his development aim for ... c5 or ... e5. This is known as the Schlechter System. Ιη the other, more active, plan, after 5 ... ο-ο Black immediately plays ... c5 even at the cost of a pawn. This intention suits the GrϋnfeΙd Defence better, 50 this is the system we shall examine ίη this chapter. After S ". ο-ο the main continuations are:

6 j"e2 6 .td3 Ιη choosing these moves White completes his development before starting queenside action. Both continuations are harmless for Black since 6 '" c5 is an effίcacious antidote Ιο them. 6 Wb3

6 .td2 - Opocensky's suggestion 6 b4 - Makagonov's variation Ιη all three cases White starts immediate queenside action, but blasting at the centre with ... c5 still secures Black's chances. 6 cd - Keres's variation This lίne was elaborated later than the others. White clears υρ the situation ίη the centre at once and opens υρ the position. According Ιο today's theory and toumament practice, the socalled Quiet System does ηοΙ cause Black problems and he can equalise. Moreover, ίη the event of a mistake by White (even a small one), he can seize the initiative and revert Ιο a tactical fight. That is why the system has become less popular recently.

The Quiet System Besides the eponymous players mentioned above, ίι should be noted that Bagirov has also enriched the theory of this line. The ideas of these players have been successfully employed, as you can see from the notes and analysis ίη the following games, by many of the greatest grandmasters - among them world champions Alekhine, Botvinnik, Fischer and Karpov - who directed the black pieces ίη those games.

Black now has the choice between pIaying ίη the classical spirit ofthe GrϋηfeΙd with ... ~xc3 followed by ... c5, or playing for ... e5 after ... .!ίJb6 and ... .!ίJc6. Both plans are satisfactory for Black. We will consider and recommend the system with ... ~xc3 which is part of Adorjan's repertoire. White's other possibility consists ίη playing .tg2 without ~c3, namely 1 d4 ~f6 2 c4 g6 3 g3. Ιη this case Black can transpose into the King's Indian Defence (as has often been done by Adorjan ιοο) by ., . .tg7, ... d6 and ... ~c6. Οη the immediate 3 ... d5 White can drive the knight to b6 ΟΓ b4 by 4 .tg2 .tg7 5 cd ~xd5 6 e4, when he can build υρ a strong pawn centre and Black does ηοΙ have the

possibility of exchanging with ... ~xc3. That is why we recommend another, maybe safer, line ίπ which . .. d5 is delayed until ... c6 has been played. ΒΥ doing this Black can recapture οπ d5 with the pawn and get good chances to equalise. This set-up was frequently played by Botvinnik and Fischer.
