Middle set 9s vs. turn 3-str8 and flush draw

[BluffTHIS!]

Joe, I was just repeating what Ciaffone and others have said in their writings, that you have to be willing to fold what might be the best hand in order to be a winner overall. This is different than limit where the pot is going to be so big that you justified in calling with outs to improve, but where in pot limit you can be getting insufficient odds to call unless you place the possibility of a bluff at a certain level (the subject of a recent thread).

And I did indicate that the play you made could be correct against known aggressive bluffers (which also can include TAGs). But that player as you described him is likely on the flop to have a two way draw and thus is more likely to hit any draw that gets there. That read is key to making the correct play.
