Chess as a sport requires a lot of mental stamina, and this is what that makes it different from a physical sport. Chess players have a unique ability of taking in a lot of information and remembering relevant bits. So, memory and mental stamina are the key attributes.
Viswanathan AnandI 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.
