CHESS

Secret weapon

Raymond Keene

Nigel Short's controversial shorts were in evidence again during the Kleinworth Grieveson British Championship at Swan- sea. Last month Zoltan Ribli, the Hunga- rian Grandmaster, protested when Short wore them at the Subotica Interzonal. Hardly surprising, since Short had won every game with them and, even shortless, he still defeated Ribli when the time came. In fact, the shorts are no ordinary pair but a peculiarly revolting set in pink and green, presented to Nigel by Dominic Lawson for the purpose of playing tennis rather than chess. My advice: hang on to them, Nigel; they may be necessary next time you face Kasparov.

Nigel slaughtered the opposition at Swansea, leading scores out of 11 being: Short 91/2; Ivanov and Conquest 8; Plaskett and King 71/2; Adams, Pritchett, Gal- lagher, Mestel, Speelman and Wells 7.

Here is Nigel's win against a very prom- ising 15-year-old, described by the Daily Telegraph as a 'Short-clone'.

Adams-Short: Ruy Lopez.

Cool defence by Black. If 27 . . . Rxel? 28 Bxf7+ Qxf7 29 Nxf7 Kxf7 30 Qb3+ and Qxb7. In the final position both Black rooks will penetrate to White's second rank with deadly effects.

Before the championship I had har- boured thoughts that Jon Speelman might win for the fourth time. His recent form had been so devastating, while Nigel Short had suffered a signal setback at SWIFT in April. Indeed, Speelman had barely lost a single game over the past year.

It was, however, not to be. Short won crushingly, while second place was shared by two relative newcomers. Stuart Con- quest, of Hastings, is still barely 21, while Igor Ivanov is one of those Russians whose careers have blossomed after leaving the USSR. He currently plays for Canada but will be in the UK throughout August playing in the BIS British Speed Cham- pionship and the Lloyds Bank Masters. Further down, the performance of 23-year- old Joe Gallagher must be noted. He is one of the hungry young men trying to fill the vacant post on the English team left by Tony Miles's 'defection.'

I have not yet been able to do justice to John Nunn's wins from the Szirak Inter- zonal. Here is a superb selection: Nunn-Marin: Sicilian Defence.

1 e4 c5 2 NO d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 6 Be3 e6 7 Qd2 b5 8 f3 Nbd7 9 g4 h6 10 0-0-0 Bb7 11 Bd3 Ne5 12 Rhel Nfd7?! 13 14! b4 14 Nd5!

Best is 12 . . . b4! 13 Na4 d5. With 19 Bb6!! Nunn, already a piece down, launches a tremendous combination.

Bouaziz-Nunn: King's Indian Defence. 1 d4 Nf6 2 Nf3 g6 3 c4 Bg7 4 Nc3 0-0 5 e4 d6 6 Be2 e5 7 dxe5 dxe5 8 QxdS Rxd8 9 Bg5 c6 10 NxeS Re8 11 Bf4 Na6 12 0-0-0 Nc5 13 13 Nh5 14 Be3 Nxe4 15 Nxe4 BxeS 16 Bd4 Bf5 17 BxeS Rxe5 18 Nc3 Nf4 19 Bfl RaeS 20 g3 Nh3 21 Bxh3 Bxh3 22

Nunn improves on the usual line: 9 . . . Re8 10 Nd5 NxdS 11 cxd5 c6 12 Bc4 cxd5 13 Bxd5 which is not truly satisfactory for Black. If 11 0-0-0 Na6 12 Nf3 Bg4 13 Bd3 Nc5 14 Rhel Nfd7!
