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 AnandIt's important, according to me, to train in small doses so as to not lose the joy of playing chess. I personally think too many coaching and training classes may take away a child's interest in the game itself. The essential thing to do is practise often and, in case of a doubt, to consult a trainer.
Viswanathan AnandWhen there's an important tournament going on, I try and stay in a bubble. It's easy that way because then you don't have to worry about anything else.
