This is about the 3rd hand into the tourney...no reads of course. Villain/Button is a winning player on OPR, although all his profit comes from 2 wins for 2007.

I'm discounting ATcc, b/c i think he bets it a very high % of the time when flop is checked to him. Is this 2-pair/badly played AQ often enough for me to shove here?
