CHESS

Arachnophobia

Raymond Keene

The chess style of Anatoly Karpov lacks the dynamism of Kasparov but his moves are for the connoisseur of gradual- ism. Karpov has been likened to a poison- ous spider, patiently spinning a barely perceptible yet ultimately lethal web. Last week I gave Nigel Short's win against Karpov as part of my preview of the match between the two in the world cham- pionship semi-final which starts today in Linares, Spain. This week I give two of Karpov's wins and the full record of the previous clashes between the two.

Total Karpov 9 Short 6

One of Nigel's problems will be how to defend against Karpov's habitual queen's pawn opening, 1 d4. In the past, Short has often resorted to the Dutch Defence. Nevertheless, this is of dubious soundness due to the 'tendency for Black to have to weaken his kingside in order to gain counterchances. I doubt, therefore, that this suspect variation will surface for the match, an observation reinforced by Nigel's use of it in the disastrous game against Karpov from the Linares tourna- ment. Patently, Nigel used the Dutch there to avoid giving away his true preparation for the match. Karpov — Short: Brussels 1987; Queen's Gambit Declined.

1 d4 Nf6 2 c4 e6 3 NI3 d5 4 Nc3 Be7 5 Bg5 h6 6 Bxf6 Bxf6 7 e3 0-0 8 Rd l Karpov adopts what had become Kasparov's favourite method, which he used several times during the 1985 and 1986 world championship matches. 8. . . a6 9 a3 c6 10 Bd3 Nd7 11 0-0 b5 12 cxd5 cxd5 13 Ne2 Karpov tries to improve on the game Portisch — Short, Brussels 1986, where 13 Bbl Bb7 14 a4 bxa4 simply led to a speedy draw. 13. . . Bb7 14 Bbl Re8 15 Qd3 g6 16 Rfel Rc8 17 Rxc8 Qxc8 18 h4 e5 This accepts the liability of an isolated queen's pawn but Nigel has seen that he can liquidate it fairly quickly. 19 dxe5 Nxe5 20 Nxe5 Rxe5 21 Nf4 d4 22 Qxd4 Qc6 23 e4 Rc5 24 Qe3 Bxh4 25 Nd3 Rh5 26 Ba2 Bd8 27 Nf4 Rg5 28 Bd5 Qc8 29 Bxb7 Qxb7 30 Nd5 White enjoys a slight advantage of superior centralisation but this is the kind of position one has to be able to defend if one is to be successful in an extended match against Karpov. 30. . .

Qe6 33 Rd3 h5 34 R13 Kg8 (Diagram) I was watching this game as it was played and here Karpov almost fell into a trap of his own making. He picked up his rook and started to move it towards 16. He knew that 35 Rf6 Bxf6 36 Nxf6+ would lead to a forced win for White but then he suddenly noticed that 35 Rf6 would be brutally punished by the intermezzo

35 . . . Rxd5. For an instant Karpov's hand hovered over the board holding the rook and then he quickly put this piece down on d3. 35 Rd3 Kh7 36 Rf3 Kg8 37 Kfl Re5 38 Re3 Qd6 39 14 Re8 40 e5 Qe6 41 Kgl Qg4 42 KW Bh4 43 RD Rc8 Nigel cracks under the constant pressure.
