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.

With the Berlin I was able to set up a fortress that he could come near but not breach.

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.

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.

So basically it's very simple: to start with, if you want to win the match, you shouldn't be afraid of him. There are still many, many things to do, but above all this is the most important: Don't be scared of him!

Chess is a matter of daily training.

Now, two years have passed and the situation is completely different: no one wants to organise this match.
