The math is right, but you are probably stacking if you are getting 231.

Effective stack after calling the raise is 354, that's more than 231. So look at it this way. . . . how often are you going to be able to stack him, and how often are you not going to get much more out of him? You are probably closer to +EV now.

I think you can stack him when a harmless jack hits often enough to call here. If he's passive enough, maybe he'll even give you a free card when you call the raise [img]/images/graemlins/smile.gif[/img].
