Carlsen will be ridiculously difficult to play against. (on the 2013 World Championship match)

India has lot of talent. What I am happy with is that the talent keeps on coming. Certainly it could be nice, though I am not terribly keen on seeing my successor yet.

Confidence is very important - even pretending to be confident. If you make a mistake but do not let your opponent see what you are thinking then he may overlook the mistake.

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.

I don't know how many calories an average chess player burns per game, but it often exceeds that of a player in ball games. It is not only the chess as such: You need to be fit and undergo complicated preparation.

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.

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