I like to keep myself physically and mentally fit before any important match. I usually take a short nap just before the game and do not practice immediately before the tournament.
Viswanathan AnandFor me, chess is not a profession, it is a way of life, a passion. People may feel that I have conquered the peak and will not have to struggle. Financially, perhaps that is true; but as far as chess goes, I'm still learning a lot!
Viswanathan AnandIt 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.
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.
