Final rally

Raymond Keene

ASmyslov's match situation became in- creasingly desperate he sought to lash out and challenge Kasparov in the tactical sphere. For game 11 Smyslov adopted the volatile and highly unusual Chigorin Defence, while in game 12 he went for an all-out blitz against his opponent's King, even at the cost of heavy material sacrifice. When I wrote last week that Kasparov's style has been evolving and maturing towards a more positional one, this in no way implied that he had forfeited his grasp of tactics and combinations. He put these talents into excellent use in those two games, scoring a further one and a half points, sufficient to persuade a demoralised Smyslov to sue for an early peace in game 13, thus conceding the match.

I spoke to correspondents of the Moscow-based chess magazine 64 im-

mediately after game 13. They claimed that Smyslov missed nothing in his conduct of the attack in game 12, and that Kasparov's defence was ironclad and perfect. They also said that after game 5 of the Smyslov match, Gary was no longer mentally facing Smyslov, but Karpov himself. In fact, the Kasparov-Karpov world championship match has been set by Fide for September of this year. The new regulations state that even if the two contenders come from one and the same country, other nations may still make bids, which, if superior, will be accepted by Fide. What a coup it would be if we could stage all or part of the cham- pionship match itself! Should any readers have suggestions, plaese do not hesitate to contact me. If we could pull this off as well as the semi-finals, it would really put UK chess on the Fide map!
