King's Indian

Raymond Keene

One of the most attractive features of Kasparov's style is his willingness to defend against OP openings with the sharp King's Indian Defence. This is a defence (or rather, counter-attack) which often appeals to aggressive young players, as it did to the youthful Bronstein, Tal and Fischer, but as masters mature they tend to shift towards the more stable Nimzo-Indian, or the ultra-solid Orthodox Defence to the Queen's Gambit. It is noteworthy that the risky King's Indian has never exerted any kind of appeal over Karpov or Korchnoi. So it is invigorating to see a great player, as Kasparov undoubtedly is, prepared to enter the maze of complications to which the King's Indian beckons.

This week's turbulent game with the opening is taken from the supertournament now in progress in Moscow. Beliavsky — Kasparov: Moscow April 1981; King's Indian Defence, Samisch Variation.

1 d4 Nf6 1 c4 g6 3 Nc3 Be 4 e4 d6 5 0 0-0 The essence of the K.I.D. is to let White establish a massive pawn centre, and then undermine it by blows from the flank, or the central thrusts. . .c5 and. . . e5. 6 Be3 Nc6 7 Qd2 a6 8 Nge2 An earl Kasparov game (Black v Lputjan, USSR 197 went: 8 Rbl Rb8 9 b4 e5 10 c15 Nd4 11 Nge2 c5 12 dxc6 bxc6 13 Nxd4 exd4 14 Bxd4 Re8 15 Be2 c5 16 bitc5 Nxe4! 17 fxe4 0h4 + 18 g3 Rxbl + 19 Kf2 (19 Nxbl Qxe4) 19 . . .

The move chosen is a great surprise, since it gravely weakens the d5 square, not to mention the Black pawn on d6. Kasparov, however, has a vastly more ambitious sacnficial scheme in mind than the one mentioned above. 13 Nd5 b5 Kasparov pondered for one hour and eight minutes over this, which offers the exchange. 14 Bb6 Qd7 15 Nc7 Rb8 16 Nxe8 Qxe8 17 Be3 Beliavsky likes to keep things under firm control (although he has not been too successful in this aim so far) so he retreats his valuable QB, rather than entering the obscurities of 17 cxb5 Rxb6 18 bxc6 d5 19 exd5 c4 or 17 . . . axb5 18 Be3 d5 19 exd5 Nd4. 17 . . . bxe4 18 Nc3 Be6 19 Be2 A stronger possibility may be 19 Nd5 although it is

The latest scores in the Moscow touril; ment (after five round) are: Karpov %A Kasparov and Smyslov 31/2; Portisch Andersson 3; Polugayevsky, GheorghltiA and petrosian 21/2; Balashov, Smejkal Torre 2; Belgavsky, Timman and Gehe' Ph. It was hoped that Seirawan and Miles the would also participate to spice UP Western challenge, but the former preferred to accompany his principal to Lone Piflie (where Korchnoi won first prize) wIlucl Miles experienced difficulty with travel an visas and decided not to go.
