[Percussion]

your getting great odds here, I would have to say call and try to see what develops on the turn (I know backdoor low, and flush draw is unlikely) but calling with what, 4.5/1 odds against an aggressive player with possibly the best hand seems a little weak--keep in mind he has position, and that flop looks horrible. What if you had A23Kds?

Now by calling the turn you are telling villian you are pretty much pot committed, so he would probably stop bluffing (if he is of course) oh, and if he isnt, just make sure theres a couple of aces on the turn and river, and im sure you will end up ok!!
