Chess

Things to come

Raymond Keene

T t was a frustrating feeling last Friday to Isee my column appear without precise in- dications as to whether London would stage the Candidates' semi-finals or to the identi- ty of our sponsors. In fact, the news broke on Thursday, too late for me, but in plenty of time for the dailies. So now it is no secret that Smyslov-Ribli and Korchnoi-Kasparov — the latter clearly the most exciting match held in the West since Fischer-Spassky 11 years ago — will both be in London, with Acorn computers as the sponsor. The open- ing ceremony will take place on 2f) November, with the first Korchnoi- Kasparov game on 21 November and the Smyslov-Ribli match beginning on 22 November. The venue will be the Hamilton Ban- queting Hall of the Great Eastern Hotel at Liverpool Street. Starting time will be 4.00 pm every day, and entry to watch each game £5. We hope that all chess lovers throughout the country will support our ef- forts by visiting this great event, the most important chess match ever held in the UK. Further inquiries can be directed to the British Chess Federation at St Leonards-on- Sea 442500. Meanwhile, the 4th Chequers Competi- tion and £200 has been won by Paul Kane, 19 Sterling Grove, Whitefield, Manchester. On this occasion there were in excess of 120 entries, so it seems an opportune moment to upgrade the competition's level of dif- ficulty. Next week, in fact, I shall reveal full details of a new Chequers Competition run- ning until the end of the year, with a £500 prize at stake. Finally, Karpov has narrowly won Tilburg, the closing scores being: Karpov 7/11, Ljubojevic and Portisch 61/4, Sosonko and Vaganian 6, Hubner,1/4 Polugaievsky and Spassky 5, Andersson and Timman 5, Seirawan 41/4, Van der Wiel 31.

Here is another sharply contested game from that tournament: Timman-Polugaievsky: Nimzo-Indian Defence; Tilburg 1983.

1 d4 N16 2c4 e6 3 NO Bb4 4 e3 c5 5 13d3 0-0 6 a3 The bold Samisch Variation, whereby White contracts double pawns but increases his chances of an attack against Black's K. 6 ... Bxc3 + 7 bxe3 Nc6 Here 7 ... d5? was played in Kasparov-Ivanovic, from Niksic. 8 Net To this square, rather than f3, since White does not wish to block the advance of his f pawn, 8 b6 9 e4 Ne8 Sidestepping the pin Bg5. 10 0-0 Ba6 11 f4 Na5 Boldly ignoring White's K-side demonstra- tion. In contrast, 1 I d6 fails to hinder White's plan e.g. 11 d6 12 f5 e5 13 f6! Nxf6 14 Bg5, followed by Ng3, with carnage. 12 f5 16! Correctly halting the further push of White's f pawn. 13 Nf4 cxd4 14 Qh5?! Both 14 cxd4 and 14 Position after 19 Rh3
