Where did I go wrong?

[esspo]

Bay 101 80-160

SB is thinking aggressive player. I haven't played with him enough to know if he is too aggressive for his own good.

Folded to horrible player in hijack who open limps, CO folds, I raise the button with AKo, SB 3-bets, BB folds, horrible player calls two cold, I cap and both call.

Flop: QJxr. Checked to me and I bet, SB calls, horrible player folds.

Turn: x. Check-bet-call.

River: x. SB checks, as I check I say "you got me AK".

Comments appreciated.
