How much to raise with 1500 stacks?

[Tater10]

I'm having the same problems at pokerroom.

Hero gets AA 1st hand of the tourney, raises to 125. 2 callers.

Flop 9h 8h 8c.

Hero bets $200, Villan #1 folds, Villian #2 raises all in. Hero (now) folds. Hero has 1100+ chips left with 10/20 blinds and can find out later if the guy is a donk.

Hero calls on party, not much chips left.
