Just before the recent Intel/PCA title match began, Garry Kasparov accepted a challenge for a $500,000, six-game contest early next year against the computer, Deep Blue (formerly known as Deep Thought).

Last year, Kasparov was horrified to lose to a machine in a quick-play event, but if the newly designed hardware performs to expectations, Deep Blue may calculate a thousand times faster than Genius 2, the program which beat Kasparov. Yet the champion will probably win without much difficulty.

The top humans, after some humiliating experiences against computers, are beginning to understand how to play against them. The following game decided first place in this year's Aegon, Man versus Machine, tournament in the Hague. Keep the position closed, manoeuvre patiently, avoid tactics and its chips are fried.
