I attend to my fitness. I go the gym every day and try to maintain my physical fitness; without that, it is tough to take challenges on the chess board.

When I started out playing chess as a kid I thought I should be world champion. As a kid you have no idea what that means and you only sort of picture it. It is hard to imagine that I waited all those years and it happened in a late stage of my career.

Chess as a sport requires a lot of mental stamina, and this is what that makes it different from a physical sport. Chess players have a unique ability of taking in a lot of information and remembering relevant bits. So, memory and mental stamina are the key attributes.

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.

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.

It'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.

In 1996, the players at the VSB tournament in Amsterdam sent me a card for my wedding with this dedication, 'Anand congrats on your wedding. You were a great player, now be ready to lose 50 points'.
