Next time you sit down to play a match, ask yourself what is your aim in playing. Are you aiming to play the best moves? Or are you playing to win? There is a difference. Many players aim merely to play the best moves, objectively speaking. They never succeed, of course, but that doesn’t stop them trying. But chess is not a science — it’s a game, a struggle between two mortals who make mistakes, deceive themselves and each other, get tired, allow themselves to be distracted, and altogether have no hope of attaining perfection at the chess-board. If you want to become a Tiger, you must forget about playing the best moves and concentrate on winning.
