CHESS

Chaos theory

Raymond Keene

THE MOSCOW OLYMPIAD has been full of spills and upsets, both on and off the chessboard. In the chess-political sphere Kasparov has been actively lobbying for Campomanes, his former arch-enemy, in the Fide presidential election. For support- ers of both the Professional Chess Association and the World Chess Feder- ation, who had previously drawn their bat- tle lines and insisted on no compromise, the Kasparov-Campomanes love-in must have made them feel that the world had been turned upside down. Henceforward, the PCA and Fide will jointly run the world championship, but I imagine that there must be plenty of disgruntled troops on both sides, quite ready to stab their former leaders in the back should anything go wrong. After all, that is the experience they have just gone through. I feel particularly sorry for PCA-sceptics Karpov, Gelfand and Salov, formerly loyal adherents of the Fide line, who steadfastly refused to play in the rival PCA events such as the speed chess world cup and have now seen the very world championship itself delivered bound and gagged by Campomanes into the PCA's hands. The PCA too will find that erstwhile supporters, such as the US grandmaster Larry Evans, will be less vocif- erous now in their support. Many PCA enthusiasts had volunteered for the cause simply and solely to see Campomanes removed from office.

Kasparov himself has invested so much effort in canvassing for Campo that his chess has suffered. Particularly painful for him must have been his demolition by the young Bulgarian Topalov. Although Kas- parov bounced back in the very next round to score a brilliant win against Lautier, the champion's general performance has been lacklustre, with numerous draws. The fol- lowing two games are the exception.

Meanwhile, the fractious negotiations which preceded Moscow concerning the captaincy and composition of the English team may have been taking their toll. Jon Speelman, ever the optimist, said: 'The team mood is now okay; there are about 12 teams with good chances for a medal, and we are one of them.' This sunnyni terpretar ton was, however, directly contradicted by Tony Miles, who opined: 'There is no tear and the atmosphere is bad.' Miles was Or ported in his assessment by Dr John Nunn who, so far, has had the most disastrous personal result in the English line-"P' Nunn said: 'I'm afraid that the conflicts sv' had about Nigel Short and the captaincy have a lot of influence on our perf°r mantes. In fact, I spent much more time talking by phone about all these problems than in training.'
