CHESS

Opening gambit

Raymond Keene

The centenary world chess cham- pionship has started in London amidst a fanfare of publicity and spectacle. On Sunday 28 July the match was formally Opened by the Prime Minister, Margaret Thatcher, in the ballroom of the Park Lane Hotel, which will also serve as the playing hall throughout the match.

To a background of music played by the Coldstream Guards, four hundred guests watched Mrs Thatcher conduct the draw- ing of lots. Challenger and former world champion, Anatoly Karpov, drew White in the first game. The current world cham- pion, Gary Kasparov, was to have the black pieces.

As she was leaving the ceremony Mrs Thatcher remarked that chess 'is rather like mathematics. . . you need to learn it Young to get used to it and get it into your bloodstream'. She also noted that young people take to chess and computing more quickly than adults. Indeed, the links between chess, mathematics and compu- ters are very strong. Chess is undoubtedly a discipline which instructs children in the modes of logical thought necessary for success at maths and in the new computer technology. With this in mind the British Chess Federation has arranged that subject to availability of seats, schoolchildren will be able to attend the games of the match free of charge.

The world championship, sponsored by Save and Prosper and funded by the GLC, will run until the end of August in London, where twelve games will be played before the players leave for the second half of the match in Leningrad. Games take place on Mondays, Wednesdays, and Fridays from 5 p.m. I had hoped to annotate the first game of the match, played on 28 July. In the event it was an evenly matched draw and I am therefore looking backwards to the first really controversial world championship in modern times — the clash between Bobby Fischer and Boris Spassky in 1972. I have chosen Game 3 from that match, the first game of the series to be won by Fischer, who had the black pieces.
