I also beat him CE Bison vs CE Bison. I could probably beat him with some of the other characters I'm good with, but I went with the safest option for the tourny.
Just because CE Bison is good doesn't mean you automatically win, you just have to be better than the person you are playing.
Hell, Alex Wolfe won Evo last year in HSF2 with ST Dhalsim. It's just that CE Bison takes a great game and turns it ugly real quick. I prefer Super Turbo, as does most of the US Pro players, but the Japs are still playing HSF2, so maybe they know something we don't. I doubt it though, I think the US definitely has an edge in SF2.
ps sirlin.net to all of those who were crying, you really should read the play to win articles
