World chess champion Garry Kasparov outmaneuvered the computer Deep Blue on 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 the IBM computer, which has a calculating capacity of 200 million moves a second.
``Kasparov managed to develop a plan that extended beyond the computer's horizon,'' said observer David Levy, vice president of the International Computer Chess Association. ``Arguably, the computer didn't know what was going on.''
Feng-hsiung Hsu, the architect and principal designer of Deep Blue, ceded defeat after 5 hours, 45 minutes.
Kasparov, 32, had suffered a startling loss Saturday in the first round when the computer took advantage of the Russian's wide-open, aggressive attack.
Play resumes Tuesday in the series, which coincides with the University of Pennsylvania's celebration of the 50th birthday of the ground-breaking computer ENIAC.
The duel is the first to pit human being against machine for a regulation, six-game chess match.
Kasparov, at age 22, became the youngest world chess champion when he defeated fellow Russian Anatoly Karpov.
In 1989, he proved critics wrong by handily defeating Deep Thought, IBM's prototype for Deep Blue.
The improved version, however, boasts an talent no human can match: shifting through more than 200 million possible chess maneuvers per second.
In Saturday's opening game, Kasparov ceded defeat on the 37th move when Deep Blue pinned his king between a knight and a rook.
``I know my opponent is invisible, but I strongly believe that it's not invincible,'' Kasparov said before that match.
Saturday's three-hour defeat was much quicker than Deep Blue's design team had even dared to hope, IBM computer engineer Chung Jen Tang said after the match.
``We knew the computer had great strengths, but we weren't sure if it was up to the caliber of the world champion,'' Tang said.
After the loss, the 32-year-old Russian left Philadelphia's Convention center without saying a word.
