I don't think I can offer any answer to the theoretical angle to your question but I wouldn't be touching this hand with a barge pole.

Against 2 opponents I'm folding the flop here. If both shorties have committed themselves pre-flop (i.e. he has @ pot sized bet or less when he sees flop) then I might call.

If you think he's likely to raise pre-flop and bet on less than TPSK then your going to get a better spot than this to take him.

Either way, I don't understand the call. Either you think you're ahead or you don't. Raise or fold. You have no draw to speak of and if you did you have no implied odds cause he's short. I'd commit his stack now if you think you are ahead.

wow... loose flop call.

if the action was bet (ai) fold fold and i closed the action, i'd call. as it stands, the middle caller would scare me enough to fold.

as for ranges, villain's range is so wide that you're probably in pretty good shape (you're getting 3.5:1 or so, right?)
