Black death

Raymond Keene

With the Phillips and Drew over, several of the players transferred directly to the next super-tournament, at Bugojno in Yugoslavia. True, Karpov was not present, but his absence was amply compensated for bY Gary Kasparov, who raced to first prize ahead of Polugayevsky, Timman, Andersson, Larsen, Hubner, Spassky, Petrosian and six other Grandmasters. 'asparov was devastating with the White pieces, as this week's games show.

IliCasParov — Petrosian: Bugojno, May 1982; ogo-Indian Defence. 1 d4 Nf6 2 c4 e6 3 Nf3 Bb4 + 4 Bd2 Qe7 5 g3 14d2+ 6 Qxd2 0-0 7 Bg2 d5 8 0-0 doc4 9 No3 c5 In the game Speelman-A.ndersson from the P + D a Couple of weeks earlier, Black had drawn easily With 9 ... Rd8 10 Nxc4 c5 11 Rfdl Na6. Here Kasparov improves White's play by capturing on c5 to exploit White's lead in development. 10 dx,"I Qxe5 11 Rac1 Nc6 12 Noc4 Qe7 13 NfeS '1xe5 14 NxeS Nd5 15 Rfdl Nb6 16 Qa5 g6 17 Nd5 18 e4 Nb6 19 Bfl Re8 20 Rddl Rf8 Black is completely paralysed since he cannot

bring out his Q-side pieces. 21 a3 Kg7 22 b3 Kg8 23 a4 Rd8 24 Qc5 Black resigns. If 24 ... Qxe5 25 Rxd8 + Qf8 26 Rxf8 + Kxf8 27 a5 or 24 . . Qe8 25 Qc7 Nd7 26 BbS. One of the most crushing defeats of Petrosian's career and one which must have been sweet revenge to Kasparov, who had twice lost to the ex-world champion in earlier games, both from winning positions.

Kasparov — Najdorf: Queen's Indian Defence. 1 d4 Nf6 2 c4 e6 3 Nf3 b6 4 a3 Bb7 5 Nc3 d5 6 cxd5 Nxd5 It is a puzzle to me that so many players prefer this risky recapture to the solid 6

Psahis continued with the quiet Radl but Kasparov has something much more dynamic up his sleeve. 19 Nd4! Qxe5 20 Nf5 Bf6 21 Qg4 Rce8 Preparing to give up his Q for 2 rooks to break the back of White's attack, but he has overlooked a trick. 22 Bd2 Qxal 23 Rxal Bxal 24 Nxg7! Bxg7 25 Bh6 Black resigns. After 25 ... Rel + 26 Bfl there is no defence to Qxg7 mate. The 72-year old veteran, Miguel Najdorf, was originally invited as chief arbiter, but brave- ly opted to play when Vlastimil Hort withdrew after a heart attack.

Kasparov — Gligoric: Queen's Indian Defence. 1 d4 Nf6 2 c4 e6 3 Nf3 b6 4 a3 c5 5 d5 Ba6 6 Qe2 exd5 7 cxd5 g6 8 Bf4 d6 9 Nc3 Bg7 10 Qa4 + Qd7 11 Bxd6 Qxa4 12 Nxa4 Nxd5 13 0-0-0 Ne7 14 e4 Boll 15 Rxhfl Nbe6 16 Nc3 (Diagram) 16 Rd8 17 Nb5 Rd7 18 Bf4 Rxdl+ ?

Korchnoi's son Igor has at last been releas- ed from prison camp in Russia and he and Korchnoi's wife Bella have renewed their application to join Korchnoi in the West. Unfortunately Igor was promptly presented with a new call-up order for the Soviet army and if he refuses once again he will be in- volved in a vicious circle of detention. The Soviets have extracted more than their pound of flesh from Korchnoi's family.
