AQs Facing Three Barrels

This hand was shared with me by WCGRider, UTG is 27/20 over a few hundred hands and the caller in the small blind is a fish.

Preflop: Hero is MP3 with Q, A
Pipedreamzz raises to $35, 3 folds, WCGRider calls $35, 2 folds, Put up ur Dukes calls $30, 1 fold
This seems like a fairly standard course of action. Folding is out of the question and 3-betting for value doesn’t really fly against and UTG raiser because he probably isn’t putting more money in with much worse given the situation.

Flop: ($115) 7, J, 3 (3 players)
Put up ur Dukes checks, Pipedreamzz bets $66, WCGRider calls $66, 1 fold
Raising is definitely a viable option and I think it would be clsoer if the pot were heads -up. However, given that we wouldn’t mind the fish tagging along and that we can outplay Pipedreamzz on alter streets if we miss, I like a call.

Turn: ($247) A (2 players)
Pipedreamzz bets $144, WCGRider calls $144
A great card, but I don’t see how we can raise here. Not many worse hands will be playing for stacks given our line and the board, better just to under represent our hand and call for value. Important to note the ace represents a pretty good barrel card for him, whether he has one or not.

River: ($535) K (2 players)
Pipedreamzz bets $400, WCGRider???
Doesn’t change too much and the villain has fired a pretty solid bet at us. Given the stats we have on him over a limited sample and the passive nature of our play this is pretty awkward. Hands that he would three barrel for value like AJ/AK/KJ and sets are certainly a decent portion of his range, but I jsut feel like our hand looks like its so weak. In his mind we can never really have a set or aces up here, so its a pretty good opportunity for him to turn a hand into a bluff on the river. Not fist-pumping by any means, but I like a call here. Thoughts?
