NEW YORK (Reuter) - World chess champion Garry Kasparov slowly squeezed
the best chess-playing supercomputer into submission Saturday to win the
first game of their $1.1 million re-match in New York. 

The game began with a quiet, closed opening more suited to the 34-year-old
Russian grandmaster's ability to form long-term judgement about his game
plan, then exploded in the middlegame with a sacrifice by Kasparov and
ended with the champion forcing home a positional advantage. 

``It is already different from Philadelphia,'' a beaming Kasparov told an
auditorium full of 450 spectators in the Manhattan office complex where
the 6-game match is taking place.  He was referring to his game one defeat
by Deep Blue in their first contest in February 1996. Kasparov recovered
from that loss to win the match overall. 

Spectators, expert observers and the team of scientists who created Deep
Blue, an IBM RS/6000 SP parallel processor with specialized microchips for
chess, applauded Kasparov's victory with the white pieces. 

``Kasparov won this game with such finesse,'' said International Master
Maurice Ashley of the United States, who was one of the official
commentators. ``His understanding of the computer's weaknesses was pushed
to a higher level today.''

The key moment of the game came on Deep Blue's 28th move, when the
complications that arose from its kingside pawn thrust led to the exchange
of a white rook for a black bishop and pawn two moves later. 

Kasparov's risk in allowing the loss of the more valuable rook paid off
because it gave him the space to obtain the advantage by marching two of
his own pawns down the kingside supported by a bishop and a rook with the
black king stranded.  The IBM programmers resigned on the 45th move after
some 3 hours and 45 minutes play. 

``It was very complicated and tense,'' Kasparov said. ``I couldn't
calculate the position but I felt with these two pawns it would be enough
in the endgame.''

Kasparov frequently says that the machine's huge calculating powers are no
match for his vast experience and intuition about chess. The Russian,
world champion since 1985, is considered by most experts to be the best
ever player of the ancient game. 

The computer, which can search hundreds of millions of positions per
second was always ahead of its human opponent on the clock. In Sunday's
second game, Deep Blue will play with the white pieces. The match ends May
11. 

``We have some work to do tonight,'' said IBM's Murray Campbell, one the
computer scientists on the team. 

The computer's sole win in last year's match created chess history because
it was the first time a program had defeated a reigning world champion in
classical chess, in which games can last several hours. 

In each game, the players have two hours each to play 40 moves, then one
hour each for the next 20 moves and an additional 30 minutes each to
complete the game. The winner of the six-game match will receive $700,000
and the loser $400,000. 

The contest 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. 

Chess playing is considered ideal for computers because the game involves
a specific number of physical objects governed by simple, clearly defined
rules. Information on the contest is carried on the IBM Web site
www.chess.ibm.com. 

Kasparov strode into the playing room confidently and went on to play with
authority. 

``It was a tremendous effort by Kasparov, he exposed the computer's
weaknesses,'' U.S. grandmaster Patrick Wolff said.
