Whats my action?




Second hand was vs ultra aggr. guy. Nevern seen something like that before!
I already made some dollars from him simply by check calling things like middle pair and lower. He started betting on later streets though, not on flop.
Once I raised by mistake with A9o OOP to 2 bucks (thought I had AQ but realized it was on a different table ) he calls. Flop 83K rainbow. chk chk. turn K ... i chk he overbets pot and I raise allin, he folds. He never had a good hand when he overbet pot before.
Here some stats from him:

Is this played correctly and river is a 100% standard call? I realized as soon as he has the ace i'll only beat A4, A6 and A7
