WPT 10K hand, Day 2 (Foxwoods)

[HiatusOver]

Villian in the hand re-raised the chip leader in hand #1 of the day from 2500 to 6000 pre-flop. Chip-leader folded. Then the very next hand he made it 2000 to go in MP (blind 400-800 with 100 ante) folded to BB who called...flop 763, check-check. turn 4, check-BET SMALL-raise-VILLIAN PUSHED. Villain also raised UTG a few hands later to 5 times the BB and took it down. Meanwhile I havent played any of the first 9 hands dealt on Day 2 when this hand comes up...

THE HAND

Folded to me TWO OFF the Button, I have yet to play a hand and make it 3000 to go with AKo(Blinds 400-800 with 100 antes, My stack 27.5K.) Villian makes it 6000 to go from the Cut-Off, his stack is pretty much the same as mine. Folded back to me, whats my action. I have done a lot of thinking about this hand by myself and with friends and have come up with some decent conclusions but I figured I would run it by the forum.
