CHESS

Ihave not yet given any of Kasparov's wins against Miles from their match. This week I make amends by publishing their amazing 6th game with variations shown to me personally by Kasparov.

Miles — Kasparov: Game 6, Slav Defence, Meran Variation.

1 d4 d5 2 c4 c6 3 Nc3 Nf6 4 e3 e6 5 Nf3 Nbd7 6 Bd3 dxc4 7 Bxc4 b5 8 Bd3 a6 9 e4 c5 10 e5 cxd4 11 Nxb5 Ng4 12 Qa4 With the score 41/2-1/2 against him, it must have taken real courage to play such a double-edged variation in the final game. Afterwards Miles agreed, saying, 'I knew I was probably crazy to play 12 Qa4'. 12 . . . Ngxe5 13 NxeS NxeS 14 Nd6+ In the chess encyclopaedia, Korchnoi gives 14 Nc7+ Ke7 15 Nxa8 Nxd3+ 16 Ke2 Ne5 17 Qb4+ Ke8 18 Qb6 Qxb6 19 Nxb6 leading to a big advantage in the endgame. But much better is 17 . . . Kf6! 18 Qd2 Ke7! with equality. 14 . . . Ke7 15 NxcS+ Kf6! For the second time in the match (as in game 3) refusing to capture a knight that has taken a bishop. 16 Be4 If 16 Bxa6 Nxd3+ 17 Ke2 Nb4! (17 . . . Nc5 18 Qc6 d3+ 19 Kdl Qd5 20 Qxd5 exd5 21 Nb6 is better for White) 18 Qb5 h6 (or . . . Kg6) 19 Bb7 Ra5 20 Qc4 Rc5 is unclear. 16 . . . Ftxc8 17 h4? 17 0-0 Rc4! 18 Qxa6 d3 is fine for Black e.g. 19 f4 Qd4+ 20 Khl Ng4. Nevertheless, 17 0-0 would have been the correct course. Miles had overlooked a tactical point and in the further course of the game the weakness on h4 is of great use to Black. 17 . . . h6 18 0-0 Miles had missed a complex variation namely 18 Bg.5+ is answered by 18 . . . hxg5 19 hxg5 + Kxg5 20 Rxh8 Rc4! 21 Qb3 Bb4+ 22 Qxb4 Qxh8 23 0d2+ Kf6 24 Qf4+ Ke7! when Black is much better. 18 . . . Rc4 19 Qdl d3 20

Rfel Rxcl! 21 Rxcl d2 22 Rfl Qd4 If now 23 Rc8 Qxe4 24 Qxd2 Bb4 25 Qe3 Nf3+ !! and Black wins. 23 Rc2 Qxe4 24 Rxd2 Bc5 25 Rel Qxh4 26 Qc2 Bb4 27 RxeS If 27 Re4 Nf3+ ! 28 gxf3 QgS-F wins. 27 . . . Bxd2 28 g3 Qd4 29 Re4 Qd5 White resigns.

The notes to the above game were dictated to me by Garry Kasparov in his suite in the Sarria Hotel, Barcelona, on 3 June 1986, the evening of the day on which he was presented by El Corte Ingles with the Chess Oscar for the best performance of 1985.

To round off, here is the 8th game from the Kleinwort GrievesOn UK-USA Chal- lenge:

Alburt — Speelman: English Defence.

1 Nf3 b6 2 d4 Bb7 3 g3 Needing only a draw to win the match, Alburt proceeds quietly, though perhaps, unwisely, against his natural tempera- ment. 3 c4, 3 Nc3 are alternatives. 3 . . . g6 4 Bg2 Bg7 5 0-0 Nf6 6 c4 e6 7 Nc3 Ne4 A curious hybrid between the King's and Queen's Indians. 8 Nxe4 Bxe4 9 Bg5 Qc8 10 Qd2 h6 11 Bf4 d6 12 Nel Consistently heading for exchanges, pre- sumably happy to increase his chances of a draw. 12 Rfdl or Racl with the intention of c5 looks more promising. 12 . . . Bxg2 13 Kxg2 Qa6 14 b3

Nc6 15 Be3 Ne7 Thus Black has been allowed to solve all his problems. White's position is somewhat discoordinated. The Be3 is particular- ly awkwardly placed. 16 f3 c5 17 Nc2 Rd8 18 a4 Played just as much to free the Ral as with the idea of a Queen's side attack. 18 . . . d5 Definitely seizing the initiative. Black's pins on the h8-al diagonal and on the 'd' file suffice to gain material. 19 cxd5 Rxd5 20 Bf2 cxd4 21 NM Of course, 21 Nxd4 e5 wins. 21 . . . Qa5 Another pin makes Black's advantage clear. 22 Racl 0-0 23 Rfdl Rc5 24 Rxc5 bxc5 25 Nd3 Qb6 It is a testimony to Alburt's fighting spirit that he survives so long with such a difficult position. 26 Qc2 Nd5 27 Qc4 27 Qxc5 Qxb3 attacking dl. 27 Nxc5 Rc8 28 Rcl e5 is very unpleasant for White. 27 Nxc5 Rc8 28 Rcl Bf8 29 Bxd4 Bxc5 30 Bxc5 Ne3+ 31 Bxe3 Rxc2 3213xb6 Rxcl 33 Bxa7 Rbl may be adequate to win. 27 . . . Rc8 28 Rcl Qd8 29 Nxc5 Qg5 White has regained his pawn but still suffers from many disadvantages such as the 'c' file pin and a shaky King's side. 30 h4 Ne3+ 31 Bxe3 Qxe3 32 Rc2 BIB 33 b4 a5 34 Qa6 d3! A fine coup just when White appears to be getting counterplay. If 35 Qxd3 Qxd3 36 exd3 axb4 37 d4 e5 wins. 35 exd3 Now White's position is a smoking wreck. Black's last also had the effect of excluding White's Queen from the defence. 35 . . . Rd8 36 Qxa5 Rd5 37 Qa8 g5 38 a5 Bxc5, 39 BxcS Qxd3 40 kf2 RxcS King safety is of paramount importance in such positions. White cannot afford to offer the exchange of Queens with 41 Qe4 Qxe4 42 fxe4 Rica5 as this leaves him with an utterly wretched 4-3 Rook and pawn ending. However, what he plays precipitates the end. 41 Qa7 Rcl 42 g4 Qdl 43 Rb2 Qhl+ 44 Kg3 e5 45 QbS+ Kg7 46 KI2 Rfl+ White resigns.
