AA on the button. Standard?

[7ontheline]

6/12 at Ho-Chunk in Wisconsin. Not very many interesting hands to post, I was pretty card-dead except for a few big pairs. Pretty loose table with lots of rivering going on.

SB is fairly solid TAG, MP1 typical loose/passive, MP2 slightly tighter but still not very aggressive, LP1 kind of a donkey, I'm on the button with black Aces.

Preflop:
So MP1, MP2, and LP1 limp, I raise, SB calls, all limpers call.

SB bets out, MP1 raises, MP2 calls 2, LP1 folds, I call planning to raise any non-spade/non-king turn.

Turn (9 BB)

SB checks, MP1 bets, MP2 calls, I raise, SB folds, 2 calls.

Checked to me and I bet.

Any problems here? Or super-standard?
