Lots of people thalk about Phil Ivey being the most feared player in poker...I have never seen him win one. I think being across from Johnny Chan, Doyle Brunson or any of the other old timers would be more intimidating.
You are talking about tournament play which is totally different. The blinds get so high people are forced to gamble and the cards decide a lot of times who wins. The question was who would be the most feared heads up. Phil Ivey makes millions playing poker in high stakes cash games not tournaments that you see on TV. I would much rather play Doyle or Chan heads up. They are more traditional. Ivey will push with any two cards and you could never get a read on him.
