He is the so-called father of the modern school of chess; before him, the King was considered a weak piece and players set out to attack the King directly. Steinitz claimed that the King was well able to take care of itself, and ought not to be attacked until one had some other positional advantage. He understood more about the use of squares than Morphy and contributed a great deal more to chess theory.

Too many times, people don't try their best. They don't have the keen spirit; the winning spirit. And once you make it you've got to guard your reputation - every day go in like an unknown to prove yourself. That's why I don't clown around. I don't believe in wasting time. My goal is to win the World Chess Championship; to beat the Russians. I take this very seriously.

If you don't win, it's not a great tragedy - the worst that happens is that you lose a game.
