I'm unsure whether the flop check was good or bad, I checked thinking, a bet only folds hands I beat and donates to hands I don't. However the check really doesn't tell me much about where I'm at does it? After he checked behind I was gonna lead a non-scary turn, but the turn was horrible so I checked again, he bet, I thought for a while and folded.

-How's my line?
-How should we play hands like this in general, i.e. OOP, high PP and a scare-card hits the flop?
