When I started out playing chess as a kid I thought I should be world champion. As a kid you have no idea what that means and you only sort of picture it. It is hard to imagine that I waited all those years and it happened in a late stage of my career.

There are some things we do much better than computers, but since most of chess is tactically based they do many things better than humans. And this imbalance remains. I no longer have any issues. It's bit like asking an astronomer, does he mind that a telescope does all the work. He is used to it. It is just an incredible tool that you can use.

Before a match, I do not follow any chess news except the games.

In the knockout tournaments, it's futile to prepare for a grand finale. You may have worked out many strategies for the final. But you may lose in the first round itself.

Just before a game, I try to keep a clear mind so that I can focus better. I'm the kind of person who plays fast and relies a lot on intuition, so being at peace with myself is vital. Saying my daily prayers helps me achieve this heightened state of mind.

It is important that you don't let your opponent impose his style of play on you. A part of that begins mentally. At the chessboard if you start blinking every time he challenges you then in a certain sense you are withdrawing. That is very important to avoid.

The broader the chess player you are, the easier it is to be competitive, and the same seems to be true of mathematics - if you can find links between different branches of mathematics, it can help you resolve problems. In both mathematics and chess, you study existing theory and use that to go forward.
