Garry Kasparov has two important dates in his 1997 calendar. In the autumn, he has faintly pencilled in his final showdown match with Anatoly Karpov. Before that, however, firmly written in for May, comes Kasparov's re-match with Deep Blue. The last time he met the IBM computer, Kasparov lost the first game then won one and drew two before suddenly coming to his senses and playing the sort of chess that made it clear that beneath all that calculating power the machine didn't have the faintest idea what it was doing.

The clash of human judgement and computer calculation is always fascinating, but I doubt if GK and DB will produce anything quite as amusing as this game, played against a Deep Blue last year. Bronstein has always tried to show - with moves such as 7.Ra3?! - that computers can be defeated tactically as well as strategically, but Deep Blue deserves credit for finding the cool 10...Nc6! instead of grabbing everything it was offered.
