One afterthought. There was an interesting article in the NY Times the other day in the Arts section wherein a psychologist pointed out that besides being really bright (in the photographic memory sense of the word) he also has the ability to remain cool which can act as a detriment to his opponents. After all these appearances the other players are "awed" to some extent which gives him a psychological edge---he also knows never to ring in out of desperation at this point.
