Final Position

There was nothing Deep Blue could do about those two passed pawns!

This is what Kasparov had to say about this game:

Deep Blue's position wasn't so bad in this game. 13...g5 was okay for Black - it played under its own logic, which motivated it. But then 22...g4 wasn't so good - it opened up the kingside to my advantage.

Had it not done that, then Deep Blue would have had some well centralized pieces. For instance, it could have made moves like Bd4, which keep the position under control.

Later in the game, we saw another typical computer weakness: taking the exchange. The computer doesn't understand positions with a material disadvantage. I'm sure it was very pleased with the position, but the consequences were too deep for it to judge the position correctly. I think White's position was excellent and I am positive this was a correct sacrifice.

Interestingly enough, the machine didn't spend more than three minutes per move in this game. It only took longer right at the very end of the game - six minutes on a move - when it saw the drop in evaluation. This game was a pure machine performance, which is what I had been expecting before the match. In order to win the game I had to show some good qualities. I played well: I sacrificed an exchange, I maneuvered on the first rank, then eventually at the end I played 37. Bh3 and 39 g4 to break through; it was very nice. I used the machine, I exploited its weaknesses.

Unfortunately, after game 1 Deep Blue never played in the same style again. No positional mistakes of that magnitude, and no fixed time per move. Sometimes it thought for four or five minutes per move. In two very important games - games two and four - it spent 8 minutes and then 15 minutes for two of its moves. Deep Blue probably sees more lines in 15 minutes than all chess-players in the world for the rest of their lives. I would really like to know how the Deep Blue team was able to so radically alter the machine after the first game. - Kasparov
