Who's the best celebrity poker player in the world? It was a big source of debate at the second annual "Ante Up For Africa Tournament at San Manuel Indian Bingo & Casino To Benefit Darfur" event in Highland, California on Thursday. "A couple of years ago I would have said Ben Affleck or Leonardo DiCaprio," 'Celebrity Poker Showdown' host Phil Gordon told PopEater. "It's definitely not Don Cheadle," says Gordon, needling the event co- host. "I love Don, but having played with him in a really competitive situation I can pretty much tell you it's pretty much not him."
