I hate these hands...PP 15/30

[Sully]

PP 15/30, ten handed. The button and both blinds have been LAGging it up for an hour. UTG is a decent player, and is very aware of the value of isolation here. He has been running very well.

UTG Raises, and I reraise from UTG +1 with Q [img]/images/graemlins/diamond.gif[/img]Q [img]/images/graemlins/heart.gif[/img]. Folded around to UTG who calls.

Flop is 3 [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/club.gif[/img]. Check, I bet, he calls.

Turn is T [img]/images/graemlins/diamond.gif[/img]. Check, I bet, he calls.

River is 7 [img]/images/graemlins/heart.gif[/img]. He bets and I call.

Is this a way ahead / way behind situation on the turn? I couldn't do it at the time, but this seems like a good place to check behind on the turn and see the river for one more bet, unless I hit my gutshot.

Fold the river? I called here, largely because I had just gotten done posting a hand where I made a weak fold on the river after similar action and a river donk.

Thanks for the help.
