They showed Moon bluffing a couple of times PF, but never getting out of line at all postflop (beyond a continuation).
I think given the hands he has shown up with the CR by Moon is the end of the hand. No way he doesn't have the flush beat. If he had a 2, given his play in some other hands he either bets out or C/Cs.
I think a call on the turn would have been better given the paired board, crappy flush, and situation in the Main Event with 2 big stacks. Moon doesn't want to bluff much of his huge stack here either.
Crazy, man....Crazy!
