5-10 3-Handed, Villain Loves Overbet

[9cao]

Villain buys in short for like $200 and we play heads up for about 10 minutes and then he stacks me when he overbets with the nuts. We play for another 10 minutes and I fall for it again, once again he shows the nuts.

A couple minutes later we are 3-handed. Villain has about $350ish, new guy has about $750 and I have them covered.

I limp from the button with AA, SB completes, and Villain checks in BB. Pot $30.

Flop comes 669 rainbow. SB checks, BB bets $25. Interested in what most people would do here, but I just call, SB folds. Pot $80.

Turn is a 6 and Villain moves in for around $300. Thoughts?
