100 Poker Hands

So in this hand I am happy with the play preflop and flop.  The flop is pretty good I think since I will get calls from lower pairs and flush draws. Betting the turn seems a good move too when the Jd hits.  The flush draw is still there, but weaker, and no overcards.  I am still going to bet out looking for value from lower pairs and charging the draws. I am sure that if the button has hit a set he would be raising the flop and if he hasn't done that he would almost certainly be raising the turn.  He doesn't so I think that I am still good. Then the river card comes. The cooler.  There is a big question as to whether the villain has got right the way to the river with just an over card, or possibly A2, A4, A8 or AJ I suppose.  Of course he might need to bluff the river with a busted flush draw. So I check on the river and see what he does..and he shoves.  Should I call or fold? PokerStars - $0.02 NL FAST (6 max) - Holdem - 6 players Hand converted by PokerTracker 4 BT
