Chess

London leads

Raymond Keene

The Phillips and Drew/GLC Kings Tournament has been remarkably in- novative in a number of significant respects. As in the London Candidates' semi-finals, we have taken the initiative in breaking international deadlock and this is the first non-Fide event in which Karpov and Korchnoi have played together since Korchnoi's defection in 1976. In fact, it is their first joint tournament since the 1973 USSR championships! Spectators will experience all the usual amenities, such as Bill Hartston's amusing lectures and the ex- cellent chess book stand, but, in addition, we also have, this year, in-game commen- taries by IM Glen Fear which can be enjoyed via portable earphones in the play- ing hall itself. This may be a world first. Bulletins are available at .£9.00 from the British Chess Federation, 9A Grand Parade, St Leonards-on-Sea, Sussex, while there will also be a tournament video tape,

featuring game comments, a Korchnoi in- terview and the GMs v GLC football mat- ch. IM David Goodman is producer of this. Play still runs from 3 to 11 May inclusive, though May 4 and 10 are free days. Play is from 1.15 to 6.15 pm and the big game Karpov-Korchnoi is on 5 May. All chess en- thusiasts who can should take the chance to see these marvellous players in action at County Hall. Regular Ceefax reports are on pages 193-194.

As we go to press, Karpov and Chandler lead after five rounds with 4 points, follow- ed by Polugaievesky (3 and an adjourned game) and Timman (3).

After 12 e5 Nd5 13 Nxd5 cxd5 14 Qe3 Polugaievsky-Tan, Manila Interzonal 1976, Black should, according to BCO, play 14 . . Bg6 with level chances. The point of this bishop retreat is to blunt the power of White's KB. 12 . .

Unfortunately, this consumes an enor- mous amount of tempi and also does nothing to challenge White's KB. By analogy with the line above, Black should try . . . Bg6. 18 Qxf3 Nb8 Consistent, but foolhardy. Torre must have totally underestimated the force of White's com- ing attack. 19 Bxh7 + ! Kxh7 20 Qh5 + Kg8 21 The Spectator 5 May 1984 Rg3 If now 21 .
