Queens getting squeezed after A-high flop?

[chesspain]

Online 3-6...UTG seems like a basic, weak ABC player.
UTG+1 is a lagtard who will try to steal pots, especially with position. HJ is a "show-me" idiot--after having his AQ three-bet PF, he bet/called all three post-flop streets after flopping an ace.
Preflop: chesspain is LP w/Q [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/club.gif[/img].
UTG limps, UTG+1 raises, 2 folds, chesspain reraises, HJ coldcalls three, 2 folds, SB coldcalls 8/9, 1 fold, UTG calls, UTG+1 caps, everyone calls.

Flop: (20sb) 9 [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/club.gif[/img] A [img]/images/graemlins/heart.gif[/img] (5 players).
Everyone checks!?

Turn: (10BB) 3 [img]/images/graemlins/diamond.gif[/img] (5 players)
SB checks, UTG bets, UTG+1 folds, chesspain...?

1) Folds?
2) Calls?
3) Raises, with the plan of putting no more money into this pot?
4) Raises, with the realization that by doing so the pot will be so bloated he may have to call a single bet on the river?
