My Understanding is that Paul has taught many of the best backgammon players in the world. But my understanding is that he now teaches poker. He has many top hold'em players taking lesson from him in fact many are in the shark club. At one time reports are he had 3 top sharks in the shark club at the same time. I believe he probably is one of the best teachers of the game. With a huge IQ how can he not be one of the best teachers in anything he puts his mind too.
