Commerce Cal. St. Champ. Event 2 LHE FT

[SCBet]

Down to the final table with 10 players remaining in the $335 Limit Hold'em Event 2 at the California State Championships at Commerce. 283 players started the tournament, blinds are now 2000-4000 and we're playing stakes of 4000-8000. Average is about 60k.

Hero is on the button with 66k currently in 4th place. Villain is in the big blind around 85k. Villain has been playing aggressive and raising a lot of hands pre-flop against a passive table when it was at 2 tables. Post-flop the Villain tends to continue his aggression until someone plays back, at which point he has either folded or called down. Villain seems like a knowledgeable limit player. Villain probably sees hero as a tight-aggressive player who picks his spots and fights hard for the pot once he is in post-flop.

Folds around to Hero on the button, Hero has A3o and raises. SB folds, Villain 3-bets, Hero calls.

Flop is A-J-3 rainbow. Villain bets, Hero raises, Villain 3-bets, Hero calls.

Turn is a 7 (A-J-3-7) putting 2 diamonds on the board. Villain bets, Hero raises, Villain 3-bets, Hero ?

Pot is now 90k. Hero has 26k left. It's 8k more to call on the turn, then probably another 8k on the river.

Calling down and losing will cripple Hero and leave him with 1.25 big bets. Folding will short stack Hero but leave him with 3.25 big bets and at least a small window to play back into contention. Calling down and winning will make Hero the chip leader and put him in excellent position to attack the other stacks and win the tournament.

Hero is playing for 1st-3rd because Commerce tournaments are super top heavy (1st pays $30k, 2nd $15.6k, 3rd $7.8k, while 10th pays $990). Although there are three players in the 15k-25k stack range, Hero is not looking to move up a couple places (even 7th only pays $2k).

Taking all of this information into consideration, what should Hero do?
