so what do you think he thinks about you? have you been playing loose agressive?

you bet from the button...he raises, is it not possible that he thinks you are stealing?

two diamonds on the flop, and two hearts on the board by the turn...he took control preflop and has tried to keep it the entire time...looks like he thinks you are drawing to a flush and he is trying to price you out, so he bets on the river...

meanwhile you sit on a set...oughtn't you re-raise?
