The therapeutic value of chess has been claimed for psychiatric in-patients, for violent criminal offenders and for recidivists. Now we have the first evidence that it may also help as an outlet for the aggressive instincts of footballers.

Eric, you really ought to meet Fritz. At his best, Fritz is a fearsome fighter, but he'll happily lie down and let a footballer kick him into submission. Not only that, but the last time it happened, everyone cheered.

Fritz 3 is the latest version of a computer chess program with some novel features that can make it suit any opponent. In a recent tournament in Germany, it performed well enough to secure a qualification towards the International Master title. Curiously, it scored better against grandmasters than against ordinary mortals - but there is some evidence that its lesser opponents prepared for it by buying the program (it retails for around £80) and practising beforehand. Fritz's best game was a draw againstthe Russian grandmaster Igor Glek. Black's sacrificial attack is met by a string of accurate defensive moves which leave Black with three pawns for a piece. White's 26.Qb3 and 30.Qxb7 look the height of recklessness, but were based on precise calculation. The queen returns just in time with 31.Qb8+ and 33.Qh2.

Only that time poor old Fritz was on a handicap level forcing it to make 80 per cent king moves.
