You say you don't have reads, then don't you use PokerTracker + PA hud? You'd have all these nice little stats on them.

And is it crazy to think that you could either push or fold ont he flop after the raise and the call? Because you won't have much fold equity on the turn anyway, and it could be so that the raiser has JT/QJ/KJ and the caller a flushdraw (or perhaps a straight draw). If you really think they have a better hand than you, fold.
