Computer 1, Human 1

World chess champion Garry Kasparov outmaneuvered a computer Sunday, rebounding from an opening-round loss and evening the six-game series at one win apiece.

Kasparov won the match in 73 moves with a triumphant display of long-range tactical thinking over Deep Blue, an IBM computer which has a calculating capacity of 200 million moves a second.

Feng-hsiung Hsu, the architect and principal designer of Deep Blue, ceded defeat after 5 hours, 45 minutes.

After the match, Kasparov said he had a key strategy for attacking the computer he referred to as “the monster.” He discovered that by moving for safe positions rather than direct attacks, he could lull the machine into opening its defense.
