Deep Blue Uses 'Torture' To Tie Up Kasparov, 1-1

NEW YORK -- The supercomputer Deep Blue defeated world chess champion Garry Kasparov on Sunday to tie their six-game rematch at one victory each.


Deep Blue's victory after 45 moves and 3 hours and 42 minutes play was the second time in history that a computer program had defeated a reigning world champion. The first time was in February 1996 in Philadelphia when the IBM system won the first game of their rivalry. Kasparov recovered to win that match overall.


"This was real chess, not computer chess," said Deep Blue's grandmaster consultant, Joel Benjamin. "This is the kind of game that the very best human players would be proud of."


Benjamin and other expert observers said the computer established a spatial advantage out of the opening, restricting the 34-year-old Russian grandmaster to mostly passive moves.


Usually, computers excel at complicated tactical struggles in which their massive calculating powers give them the edge. However, in this game, Deep Blue demonstrated that it "understood" positional concepts too.


"I think the computer played an excellent positional game and I was impressed by how it closed all the possible counterplays Kasparov may have dreamed of," said Czech-born grandmaster Lubo Kavalek. "It was incredibly well done."


"It was easily the best game I've ever seen a computer play and one of the best games I've ever seen anything play against Kasparov," said Frederic Friedel, the creator of a chess-playing computer called "Fritz" and one of the Russian's closest advisers. "It played very intelligent chess and this is what we've always been slightly afraid of. I'm terrified right now."


Deep Blue and Kasparov opened the game with the classical Ruy Lopez or Spanish game, sometimes referred to as "the Spanish torture," named after a 16th century chess-playing Spanish priest.


The clash between Kasparov and the machine is part chess match and part research project to help build computers that can make complex, simultaneous calculations at high speeds. Among the applications for the technology developed for Deep Blue are weather forecasting, air traffic control, data mining and molecular dynamics.
