Professional players work almost every day, for hours on end, and the emphasis is on the word 'work.' It can be with a partner or it can be alone, but professional chess is always a pursuit of something new and surprising.
Other quotes by Viswanathan Anand
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.
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.
