I raise right away on 3rd. Two have folded, nothing higher than a T behind me, I have AK as well as flush draw. It's one of those change up raises, so people can't play you for only raising with big pairs. In an overante game like 3-6, it's especially good, because you don't mind taking it down right there.

I DON'T three bet here -- no one is going away and you are building a big pot against several players who have shown at least a bit of strength with a hand that can brick off on fourth very easily. Pot equity is a very tricky concept on early streets in stud, because there are 3 big bet streets to come. Sixth street raise is very bad against the opponent, who can't possibly fold in a big pot here (unless he's a total idiot). I call the river too -- maybe he missed his flush draw and just has sixes.
