Final Table $30k Pacific - What to do?

[mjm]

9 Players remain. 2 players with $200k+ in chips, 1 of them (villan) playing very aggressive, taking lots of blinds. Other 7 players all between $50k-$85k. Blinds $2,500-$5,000.

Hero is on the button with $55k, dealt AJs.

UTG+1 (Villan, aggressive chip leader calls), folded to hero calls, sb calls, bb checks.

Pot ($20k)

Flop A,7,2 (all hearts)

UTG+1 bets $30k, Hero ???

Hero's attitude is that a top 3 finish would constitute a good prize. The difference between finishing 9th and 4th is not of much concern to Hero.
