This is a classic hand from the 2004 WSOP between Greg Raymer and Mike Matusow.
Mike never said what his read on him was, but he had to have known it was a coin flip. I really doubt that he thought that Raymer was making a move.
Even with top pair, he was a slight underdog to Raymer's two overs and a flush draw.
Question: How would you play this? It's still pretty early in the tournament, and with so many people left to get knocked out, would you call 2/3rds of your stack with top pair in this situation?
I wouldn't.
