Before a game, I avoid having a heavy meal so that I don't feel sleepy at the board. You eat to be healthy, and that generally takes care of everything. Also, you can't be too finicky, since at tournaments you tend to eat at restaurants here and there. But, as long as you're eating sensibly, it's all good.

I think the draw quotient has always been high in world championship matches because the amount of effort people put into neutralizing each other's openings. It's just now with computers that it has reached a new level.

Psychology plays a big part but I always say psychology will only be a differentiator when the players are of equal technical strength.

The Internet gives you access to a lot of material, and it's fun to sit and read. I go to something like Wikipedia and look at different topics... I find the subject fascinating. I like to read about concepts and mathematicians.

Chess is like a language, the top players are very fluent at it. Talent can be developed scientifically but you have to find first what you are good at.

Each match I play is the most important one yet.

Preparedness for a game that usually lasts four-five hours requires good physical condition and also steady nerves.
