on Judit Polgar-
Judit Polgar is known for her aggressive playing style and her tendency to track the opponents' weaker points and attack them. In more than one interview, she emphasized the psychological aspect of the game saying she prefers learning the opponent's playing style so she can play intentionally against him, then playing chess in an objective manner.
I think Fischer had it right when he said to play the board. It just seems like too weak of an idea to play the man in as mathematical a game as chess. Eventually, your lack of attention to small nuances, which inevitably happens if you're playing mainly if not wholly mindgames, will add up and you will be hurt. Playing the board however offers an objective approach to the game; make the best move possible. Of course when you're a much better player than your opponent, you naturally have a read on how they will respond to your moves but this is irrelevant for at least two reasons: 1. If you play against his mentality, and it's a weak player, you will jeopardize your position because their moves are not as sound or calculated as a better player's would be and 2. You can never be certain that they will in fact make the move you predict, even if you are right an inordinate amount of the time.
