International chess master Jon Speelman, the 1978 British champion, did some hard thinking in a match with a new electronic opponent, the £279 Sargon 2.5 chess computer. Jon Speelman was one of only 2 players (the other was ex-Welsh national champion Manny Rayner) who beat the computer on the fifth of it's seven levels of difficulty. Jon persuaded it to resign after 40 moves.
