Two pair against solid/aggro villain

[Grifter]

I like call, and then block the river if no heart falls. I think you are ahead of his range here, but I don't think you can c/r the turn for value since you are way behind his calling range. Also, I think villain checks behind anything you beat on the river (excpet maybe A2) and probably wouldn't raise anything but flush/set. I'm not at all confident about this though and I'd like to hear other opinions. should we be concerned w/ protecting against lone hearts on the turn?
