"Why does one chess player play better than another?
The answer is not that the one who plays better makes fewer mistakes. The one who plays better makes more mistakes, by which I mean more imaginative mistakes. He sees more ridiculous alternatives. The mark of a great player is exactly that he thinks of something which by all known norms of the game is an error."
