You also have to think that he was planning on showing this one off if his opponent folded. Imagine how hard that player would tilt if he laid down his set of dueces.

Its also great for building the insane maniac image, irregardless if the player calls or folds. I'm sure he bets the same way next time when he has it.

Finally, he lost 16k on this hand, but that's not even a full buyin in that game. I doubt you'd be as shocked if an aggressive player made this play in a $200 NL game losing $160. Relatively, its the same loss to him.
