From that shortlist Tom Dwan would have been my pick with Phil Ivey a very close second.
Dwan's game is a little hard to read these days as he spends so much time in Macau. I do not believe he plays with the same bravura he did when young and at times even appears quite conservative but he knows how high profile this game will be and that a lot of credibility will be at stake.
However, they really should cue up Phil Ivey for one of these high stakes duels sooner rather than later. Ivey seems to be in a good place after putting his legal issues behind him (largely self inflicted) and appears both chilled personally yet eager to play poker. I believe he is planning quite a serious
wsop schedule.
But Tom Dwan against Helmuth next- I'll take it!
