Of all the so-called superstars of poker i do think he is probably my favourite, he seems fairly human enough to enjoy the game and have a laugh, even at himself.
I know most commentators often put this down to him trying to get to read opponents - he seems just the same 'off table' or when not in a pot.
He has made some amazing reads especially in the WSOP
of 2005 - it was in the middle of his 'non-winning' run but he was still putting everyone on exactley the right hands, it was just the hands were beating him.
So instead of losing he had to fold, so his radar was perfect even if he couldnt win anything.
I have seen all but the last 4 of season 2 of High Stakes (great shows i think) and i dont think you could blame him alone for the mad donk hands that are played - Sammy Farha for starters (is he allergic to paint cards lol), Jennifer Harman sucking out a straight to Helmuths QQ (82 hole cards).
Overall - is he overrated, my opinion No, he deserves the rating
Enjoy and Peace
