[Grease]

I complete PF only as long as the BB is passive. If he's more aggro, I'd most likely muck it.

I like B/Fing the river. If he had an A, I think you'd have heard about it by now, and you'd let him check behind with smaller PP's that he would have called with if you check.

If you check, I think you must fold if he bets and you leave yourself open to be bluffed, but if you bet, I doubt he'll bluff-raise you, and you can collect a river bet a lot of the time.
