3bet AQo OTB, 2/4nl

[ajloeffl]

You got yourself into this mess by not betting the flop. He could either think you have QQ/JJ and is trying to push you off your hand, or he could have KK and hit his set on the turn or 77/88/AK/AA and be value betting. You get to play the guessing game since you let him take the driver's seat. The bet seems fairly big on the river if he is hoping for a call. Do you have some betting patterns on his river value bets?
