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.

You need to motivate yourself, no matter what-definitely when things are bad, but also when things are good. Or else, you risk becoming complacent.

Chess has given me a lot more than I could ask for. I have been able to feel special, travel the world and do what I truly enjoy. Moreover, chess players love being their own boss and hate having to wake up early!

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 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.

Before a game, I avoid having a heavy meal so that I don't feel sleepy at the board. You eat to be healthy, and that generally takes care of everything. Also, you can't be too finicky, since at tournaments you tend to eat at restaurants here and there. But, as long as you're eating sensibly, it's all good.

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