Final Position

It was discovered after the game that Kasparov could have drawn this game with perpetual check beginning 45...Qe3 46.Qxd6 Re8! 47.h4! h5!. It seems that he trusted the computer's analysis too much and just did not believe the computer would let the position be drawn!

I didn't play the opening very well - I was passive, because I thought the computer would not be able to understand and handle well the resulting position. I wish I would have played otherwise, however, in order to play 'normal' openings you have to spend a couple of months checking your openings with your computer. Every line. Because one mistake in the Najdorf Sicilian could be fatal. The level of preparation would be different. Obviously Deep Blue had a large team behind it studying the openings.

The rest of the game is history. Including my resignation in a drawn position. The truth is that I was very tired and couldn't believe the way the machine had just played. I trusted its calculations. I assumed that if the machine allowed a move such as Qe3 at the end, it had calculated everything that could follow and found wins, so I didn't even bother checking it. Costly error, as I soon found out. - Kasparov
