Kasparov versus Deep Thought 1989, was a two-game exhibition match between human world champion Garry Kasparov and computer world champion Deep Thought on October 22, 1989, at New York Academy of Art, at that time 419 Lafayette Street in Greenwich Village, New York City. Kasparov won both games quite easily.

=Quotes= from A Grandmaster Chess Machine : In October of 1989 an experimental six-processor version of Deep Thought played a two-game exhibition match against Kasparov in New York City. Although the new version was capable of searching more than two million positions per second, Kasparov disposed of it quite easily. The result was not un-expected, but Deep Thought's play was rather disappointing.

Game 1
In game 1, DT did not know what to do with its fairly good opening position. Kasparov gradually took charge, built up pressure and calmly and cautiously maneuvered his pieces to their optimal squares until the position was ripe for the kill. Only at move 40 did DT notice something was seriously wrong.

Game 2
After showing his strategic superiority in game 1, Kasparov proceeded to outcalculate DT in game 2. DT neglected the development of its pieces rather pitifully, and Kasparov put the position on fire (beginning with 10 Qd4), eventually winning DT's queen (18 Bc6). With two pieces and two pawns for the queen it didn't look all that bad yet, but Kasparov finished the job effortlessly.
