It seems to me that this is the kind of decision that is almost completely table dependent. This is the classic simibluff hand, on the come. So the question I would ask is the standered question, what is the expected value of the bet at this table. You have to figure what the chances of your opponents folding are, your chances of making your hand, and how much you would likely make if u get it. And then there is the free card senario etc.

So I cant think of any simple advice on how to play this one, there is too much variation in the correct play.
