I don't know whether computers are improving the style of play, I know they are changing it. Chess has become a different game, one could say that computers have changed the world of chess. That is pretty clear.

Intellectual effort gives me enormous pleasure

The development of beauty in chess never depends on you alone. No matter how much imagination and creativity you invest, you still do not create beauty. Your opponent must react at the same highest level.

Look at the catastrophic record Vishy Anand has against Garry Kasparov. Kasparov managed to beat him almost everywhere they played, even though Vishy Anand has belonged to the absolute top players in the world for fifteen years. This difference cannot be explained purely in chess terms, there must have been some psychology.

But with the Berlin, I was able to allow him to get near, but not quite near enough, and I knew where to draw the line with the fortresses I had set up.

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.

I made a better decision in choosing my team. Sure, I had a bigger choice of players to choose from - but I couldn't have asked for a harder working group of players who did an incredible job.
