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.

On the whole, the life of a chess professional is not as easy as it appears at first sight. One needs to devote some ten hours a day to chess and to everything connected with it - physical and psycholgical preparation.

Only he, who penetrates into the depth of the game, can express his personality in it.

Intellectual effort gives me enormous pleasure

Every month I look through some ten thousand games, so not as to miss any new ideas and trends.

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.

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.
