When I was about six, I saw my elder siblings play chess and pestered my mother into teaching me. Very soon, I was beating everyone at home, and they thought it would be good to join a club. So my sister would take me to the Tal chess club on Thursdays and weekends.

Things like the financial markets - a proper grounding in mathematics could help the common man. I believe that if people are more familiar with mathematical concepts... it can help deal with modern life, which is increasingly complex.

My parents were very supportive of my chess. When I got home after a game of chess, having missed school or something, they always made me feel very welcome; I didn't feel guilty at all about pursuing chess with such fervour. They never, for instance, perceived sports as a rival to academics.

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

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.

Being the undisputed world champion is a relief. We instituted a unified chess title, I am the absolute world champion.
