Thoughts:
Preflop: Getting 3 to 1.
Flop: My c-bets have been either getting called or raised. I thought he might check behind. With that big bet, I think there's a good chance he might be bluffing at it. He's recently taken down a lof of pots without showing his cards.
Turn: Decent card for me. I'll c/r. If he has a pair less than aces (he might, he was in the BB,) he might give it up here.
Turn push: Oh damn. He's probably got Ax now. If he is holding just an A, I still don't think I have the pot odds to call. But he's pushed about 1/3 the hands he's had, and had a lot of people fold on him. This could be a full out bluff.

Should I have just passed preflop to the big stack? Passed to his flop bet? What a mess.
