AA facing massive overbet river shove

[Willd]

Unfortately no real reads since I was 4 tabling with no pokerace (I'm gonna get it soon) but from what I can recall he hasn't been out of line or played anything really bad. From my experience massive overbets are normally from a hand that beats TPTK. Turn check is debatable but it wasn't a great board to be called on on the flop and so I opted to check behind for pot control (lol).

Fold river. I'd check the turn also for pot control.
