In chess, knowledge is a very transient thing. It changes so fast that even a single mouse-slip sometimes changes the evaluation.

In Gujarat, we had the world record of largest number of chess games in a single venue - 20,500 - and in Tamil Nadu, I have been emphasizing on the positives of chess to the authorities.

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.

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.

If revenge motivates you, go for it! But the main thing is to set your game in order.

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.
