Dwan is supposedly one of the best players in the world, notice how he always loses at WSOP, plays so many events always loses. Main Even always out early and pathetically. Edge is so small for these players, they overestimate their abilities, can't make people fold as easily.
Take a 6-man SNG, with Antonio, Ivey, Dwan, whoever, they have little edge on me, I'll play anytime.
