Did I miss a value check-raise on the river?

Preflop: Hero is SB with A/images/graemlins/spade.gif, Q/images/graemlins/club.gif.
UTG folds, UTG+1 folds, <font color="#CC3333">UTG+2 raises</font>, MP1 folds, MP2 folds, MP3 folds, CO folds, Button folds, <font color="#CC3333">Hero 3-bets</font>, BB folds, <font color="#CC3333">UTG+2 caps</font>, Hero calls.

Flop: (9 SB) T/images/graemlins/club.gif, T/images/graemlins/diamond.gif, T/images/graemlins/heart.gif <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">UTG+2 bets</font>, Hero calls.

Turn: (5.50 BB) Q/images/graemlins/spade.gif <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">UTG+2 bets</font>, <font color="#CC3333">Hero raises</font>, <font color="#CC3333">UTG+2 3-bets</font>, Hero calls.

Looks like he has Aces or Kings after the 3bet. I know its only one more bet, but anybody fold here? He had a lot of money in front of him, which I sometimes use as a tell to indicate a strong player or not.

River: (11.50 BB) A/images/graemlins/club.gif <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">UTG+2 bets</font>, Hero calls.
Raise or just call down?

Final Pot: 13.50 BB

I check/call the flop. Check/call the turn and bet the river. I would have check/called the river without the ace FWIW.
