River raise, should i call?

[Peter_rus]

So you raise with AQo somewhere not in a blind. 2-5 callers/cold-callers. Flop is A83r. You bet. Single caller in the BB. Caller is average TAG at 30/60+. Turn is 9, completing the rainbow. Bet-call. River is 7. Check-bet-raise. Now what? How much must be a pot for you to call down here? Don't forget about meta-game before answer.

Sorry for ugly English.
