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.
Viswanathan AnandThe 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.
Viswanathan AnandJust 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.
