Who raises this river?

[drzen]

Okay, villain is loose and will call down with just about anything or nothing. He's capable of a bluff in my view. His stats show him to be a bit passive (77/14/0.6) but I've seen him pull a couple of moves.

Do I raise the river? I think he only calls a raise, or reraises if I am beaten, because if he's bluffed, he's folding to the raise. Am I right? Do I just call here?

I kind of thought he might be calling this down with A high or K high, hoping to get lucky. I think he bets a ten (he's not *that* passive). I doubt a pair of 7s believes it can get lucky here. Naturally, I didn't think it was all that likely that he flushed, but I'd hate to be reraised and watch him turn over 7s5s.

And please don't say "raise preflop". I can't isolate the limpers here. The blinds will both call and I don't want to pay two bets to play this even in position.
