I'm with the OP here. Against crappy opponents I might raise here, but what worse hands are playing this hand this way? Betting on the end after many conceivable draws get there is suggestive that the opener has something. As far as worse hands go, it could be a T, a Q, two pair or a set. I don't think all that many Q's check the turn here, and same thing for two pair hands. Two pair and the set might call the river, but those don't seem like very likely hands (65, 64, 54 maybe, QT probably bets the turn). You're folding probably anything else you're beating - maybe AT calls but I doubt it. A flush is definitely not folding and probably pushing back. I think the range of flush hands that he could have is pretty substantial, and make up (I would guess) about 50% of his possible holdings that he'll call with here. So if he raises us with that flush draw, it's going to be a bad bet, in this situation.
