You're investing 2 BB for the chance to win a pot of 4 BB. I don't think that the play will work often enough to justify that outlay against a good opponent who understands the mechanics of 3-handed play.

Or to ask a better question: if you were going to try this play, why wouldn't you bet the turn? It wouldn't cost you any more, and he'd be a lot more likely to fold without improvement.
