Once he had selected the path he was going down he really had to stick with it in a 16 game match. He had to try and hit in the one direction but unfortunately for him - though fortunately for me! - he hit in the wrong direction.

Part of my preparation for the World Champion match against Kasparov was to be ready for his off-board tactics. I did not to react to them at all. Once you start thinking about these things during the game, even analysing them, you're caught.

My very first book was a games collection of Anatoly Karpov. On the whole I was attracted by positonal play with some tactics, and already then I was aiming for universality.

It made a big difference to my match stamina. I couldn't imagine I would have been so energetic during the match - it really gave me a welcomed extra boost!

In games against humans, you often win because the opponent blunders a piece, and you can often survive when you do it yourself. Against the computer, you make only one mistake - the last one.

I started playing chess when I was about 4 or 5 years old. It is very good for children to learn to play chess, because it helps them to develop their mental abilities. It also helps to consolidate a person's character, because as it happens both in life and in a chess game we have to make decisions constantly. In chess there is no luck and no excuses: everything is in your hands.
