I don't know what I was looking at, but there is my standard answer for this type of move. That response is, there is no reason to bluff the fish. Fish don't fold, that is why they are fish in the first place. For example, if the villain in this hand has a flush draw and is a fish, he is simple not going to fold, he wants to see if he can hit.

On the other hand, if you know your opponent to be weak or "thinking" a case can be made for pushing them off what seem to be susceptible made hands when a scare card hits.
