Nobody wants to hear about PF, but chances are you should fold if this is a typical line of action on this table PF (raisers and no callers).

I'd like your flop line a lot better if BB had folded (and even then, it's marginal). With two players, you have no fold equity with your check raise and not enough people for a value raise.

Unless you have a really conservative image (and no one at .25/.50 has any image at all) I think more times than not you're going to get called down by any pair.
