how whuld u have played this ?

I play it the same and fold the river. Opp is acting is out of line: he checkcalls flop and turn and goes allin acting first on the river. Either he's got a monster (probably a straight) or he's stone cold bluffing with a missed flushdraw (hearts). With that scary board I fold - theres just to many hands that beat you here.

He has you beat, although I am thinking of two pair....A7 maybe. I think you played it well.

well ill never know what he had but its nice to hear that someone whuld play this as i do..
