It is possible for chess to demand too much knowledge, so that anyone who wishes to become an outstanding player must, I think, give to it as much time and study as he would to learning some noble science or performing well something or other of importance; and yet for all his pains when all is said and done all he knows is a game. Therefore as far as chess is concerned we reach what is a very rare conclusion: that mediocrity is more to be praised than excellence. - Baldassare Castiglione, 1527
