ok...heres the set up. i limp with btn on a relatively loose/passive table. not a lot of folds pre, but there are some post flop. original raiser is running SLAA. but, isnt out of line. may just be a TAG running hot. HU on turn villain is LPP, not over a lot of hands. but is carrying an AF of 1 and a WSD of 25%.

this has to be a good spot for a semi-bluff, but how much? or do we just call w/ pos and try and bust him when the draw hits?
