Everything about this question seems to be telling you not to push all in. You're up against a strong and tricky player, and the fact that he plays the hand exactly like a straightforward player would play a flush draw should set of alarms immediately. And the fact that your whole bankroll is on the table is probably even more important. It's not about expected value anymore when you could lose all your money, because there is no long run if that happens.

With that said, you definitely can't lay it down either. Even if you're sure he has a full house, there a few full houses you beat, so just call and throw up when he turns over his cards.
