Standard AA line?

[Triumph36]

Hey all, just wanted to throw my first post in here - it's been almost 7 months since I've made an NL post because of the old forum split.

6 max 200 NL UB

Hero (Button) $267.70.
Villain1 (BB) $258.60.
Villain2 (UTG) $263.85.


Hero: Ah Ac

Pre-flop: Villain 2 calls, UTG+1 folds, CO folds, Hero raises to $9. SB folds, Villain 1 calls, Villain 2 calls.


Flop (board: 7h Ts 3d): ($28)

Villain 1 bets $9. Villain 2 calls. Hero raises to $31. Villain 1 calls. Villain 2 calls.

Turn (board: 7h Ts 3d 4h): ($121)

Villain 1 checks. Villain 2 bets $121. Hero ?

Seems fairly standard, but I just want to check up on the 2+2 popular opinion. I'm sure I'll have more interesting posts in the future.
