I feel like on that flop no one should be c/r'ing here w/o a monster--2 pair at the least. I think OOP I should just give him the pot (right?), but I decided to call since I had position and see how the turn played out. I ck behind turn b/c although I've improved, I still don't know where I'm at in the hand (great feeling).

After playing for quite a while with this guy after this hand, I think my judgement is clouded here. So, how should I play this vs. an unknown?
