AQo 15-30 PP hand

[Turning Stone Pro]

10 handed PP 15-30. Usual suspects.

I have AQo on the button. Early UTG player raises. Appears to be a typical PP player, dont know him (or her).

All folded to me. I call. (Buckshot posted a similar situation a few weeks ago . . .is calling the worst thing? I can never bring myself to muck in this situation, so the only other option is raising).

flop comes 9 7 2. rainbow. UTG bets, I raise. UTG calls.

Turn is a 6. UTG checks, I bet, UTG calls. (I am almost 100% positive he has AK)

River is an 8. (board is 97268) UTG checks.

I'd appreciate comments on every street, as well as what you would do on the river.

Thanks in advance!
