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

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.

Just before a game, I try to keep a clear mind so that I can focus better. I'm the kind of person who plays fast and relies a lot on intuition, so being at peace with myself is vital. Saying my daily prayers helps me achieve this heightened state of mind.

Psychology plays a big part but I always say psychology will only be a differentiator when the players are of equal technical strength.

I would never suggest to anyone that they drop school for chess. First of all even if you can make it in chess, your social skills need to be developed there.

Grandmasters decline with age. That's a given. There is nothing special about the age of 40, but age eventually takes its toll. That much is clear. Beyond that it's about how long you can put off the effects and compensate for them. Mistakes will crop in but you try to compensate for them with experience and hard work.

I think an important lesson from the game is that once you have made a move, you cannot take it back. You really have to measure your decisions. You think a lot. You evaluate your choices very carefully. There's never any guarantee about what's going to follow once you have made a decision.
