he Kasparov-Karpov world chess championship match, their fifth, starts in New York on Monday. Any Spectator reader in New York who wants to visit it should contact Macklowe Hotel on 44th Street, near Times Square. The match is being played in the Hudson Theatre of the Macklowe.

Kasparov is generally regarded as the favourite, but in such matches Karpov should never be underestimated. Although Kasparov has a tangible plus score in their individual encounters (plus two, expanding dramatically to plus seven if one only includes results from the past four and a half years), the champion, in spite of his fiery genius, sometimes finds himself im- paled with surprising lack of resistance on the sharp peaks of the Karpovian iceberg.

I give two samples of play to illustrate their respective strengths and weaknesses, Karpov plays too passively in the first extract and is grimly hunted down with some brilliant tactics. The second extract gives evidence of Kasparov's occasional ability to select, prepare and then actually play opening variations which lose by force. He will have to avoid this in New York if he wants to retain his title.

Kasparov — Karpov: Game 22, World Cham- pionship Match, London/ Leningrad 1986; Queen's Gambit Declined.
