I definitely disagree with all the people saying that a pf raise is possibly +ev. It's freaking 4/8 game, people! The primary reasons for raising (metagame, hand disguising) are pretty much nullified by the general sucktitude of all the people playing. If this were 15/30, 20/40, or even 10/20 I might agree. 4/8 players are by and large not sophisticated enough to employ hand reading in this or later hands.

I also think that raising pf for value is misguided. I don't have pokerstove, but good god, 67s is a tremendous implied odds hand. Even assuming for the sake of argument that it does in fact have a pf equity edge, it would be so miniscule that this would be a clear-cut situation of forgoing a (very) slightly +ev play now to increase postflop ev.

As for the main question, I would give serious consideration to folding the flop. A checkraise behind us would be awful, and as it stands right now our implied odds make calling or folding approximately break-even if we were closing the action. I think that folding the flop is probably correct, although I could be talked into a raise if we were extremely likely to buy a free card with it.
