This one really bothers me. I generally have trouble against these kind of opponents where their raise could mean anything. I am looking on advice, not just in this particular hand, but this situation in general. Fair hand OOP against a loose and aggressive opponent. Would c/c the whole way be better? In the hand as played was folding the river good or bad?
