Antonio and I would fold this preflop. But, as you can see below, that is not a universally held opinion on FR preflop play with AQo.
Laak and Esfandiari fold AQ UTG
The rest of the hand plays itself right into the "I lost my stack to AK or a full house with AQo out of position..."
But since he MIGHT have AJ or ATs, I suppose you need to call the river. If he's not the type to flat call AJ or ATs in a raised pot, then you are probably toast as soon as he calls your cb on this flop. But without a really solid read, I don't think you can find a fold here.
