AK UTG Late Stage of Tourney

$30 MTT on Pokerroom last night. ~700 entries, down to about 35, ITM but nothing meaningful until FT. I have T80k which is ~12th in chips w/ avg ~40k and leaders are 150k+. Villian has ~90k. Table action has been raise/fold for a while w/ some shorts pushing the action on occasion and some key clashes of premium hands. Both villian and I are likely perceived as TAG - I've been raising just enough to maintain my position and only hands I showed down have been premium. Likewise for the villian.

Blinds 3k/6k I'm UTG w/ AKo and raise to 15k (standard for me), folds to villian in SB who completes, BB folds.

Flop AJJ rb. Villian checks, I continue for 15k. Villian raises to 30k.

What range do you put villian on and what do you do?
