Ok, thanks for the input. I thought this was horrible when I played it, but that was because he had a set and I sucked out. However, I was looking at it and the math looks ok. Here's what I came up with:

My estimation of villians flop calling range: JJ+, 77
My equity on the turn against that range: 25%.
x=% of time he folds
What I win when he folds + what i win when he calls and I win - what I lose when he calls and I lose = 0
134x+.25(266)(1-x)-.75(132)(1-x)=0
x=0.195

Does that look right?
So if villain will fold 20% or more of the time, this is a profitable play. If his range is wider, it become more profitable.
