The Berlin Defence suited my strategy for the match. I had a defensive strategy - Actually, I had in my pocket some other sharper stuff to fall back on - but first I wanted to try the defensive strategy with Black and it worked so well.

Playing rapid chess, one can lose the habit of concentrating for several hours in serious chess. That is why, if a player has big aims, he should limit his rapidplay in favour of serious chess.

I am convinced, the way one plays chess always reflects the player's personality. If something defines his character, then it will also define his way of playing.

At some point he seemed to lose all confidence trying to break down the Berlin Wall. He was still fighting as only Kasparov can, but I could see it in his eyes that he knew he wasn't going to win one of these games.

Chess is so deep, I simply feel lost.

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.

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.
