DEEP THOUGHT - the world's strongest chess machine - won the ACM Computer Championship with a score of 4 out of 5. Its only loss came by forfeit when its power source failed.

Deep Thought is awaiting the spare parts that will complete its transformation into Deep Blue, the long-awaited custom-built piece of electronic wizardry that will think faster and better than anything yet seen. In this tournament we saw an interim version of new software on the old machine. And very impressive it looked too.

In the following game against the eventual runner- up, it played the King's Gambit (probably following its opening book rather than its better judgment) and was in definite trouble in the middlegame.

The crucial moment came with 24. Rd1] allowing the apparently crushing Re8. White's 25. Ne4]] was hard to believe, but the threat of Rxd5 followed by Nf6+ denies Black the time to take advantage of the pin.

Again after 28. Be3 Bh6, White seemed on the verge of disaster, but DT, analysing 4 million positions a second, had calculated that all was under control. Finally DT's rook was too much for Zarkov's disastrously placed minor pieces in the endgame.

The lesson for Deep Blue's future opponents is clear - go for its plug.
