Questionable on every street

[Leader]

I don't have much on UTG/MP he seems loose and moderately agro so far.
CO is a LAGTAG 34/21/2.1/40 Don't know anything about him.

Pre-flop: (5 players) Hero is BB with Q[img]/images/graemlins/club.gif[/img] A[img]/images/graemlins/diamond.gif[/img]
<font color="#cc0000">UTG raises</font>, <font color="#cc0000">CO 3-bets</font>, Button folds, SB calls, Hero calls, UTG calls.

I wanted to see what would happen with UTG since his call or caps means something IMO. Plus AQo isn't exactly awesome vs. a 3-bet and initiative is pretty worthless here.

Flop: 7[img]/images/graemlins/spade.gif[/img] Q[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/diamond.gif[/img] (12SB, 4 players)
SB checks, <font color="#cc0000">Hero bets</font>, UTG calls, <font color="#cc0000">CO raises</font>, SB folds, <font color="#cc0000">Hero 3-bets</font>, UTG calls, <font color="#cc0000">CO caps</font>, Hero calls, UTG calls.

With the pot 4 way, I figured there was a decent chance it gets checked through. So I bet. I 3-bet because my hand reads like KQ/QJs/QTs or some other weaker stuff. UTG doesn't know me FWIW.

Turn: 9[img]/images/graemlins/heart.gif[/img] (12BB, 3 players)
Hero checks, UTG checks, CO checks.

[img]/images/graemlins/tongue.gif[/img] for that. Anyone think I should have lead?

River: 5[img]/images/graemlins/spade.gif[/img] (12BB, 3 players)
<font color="#cc0000">Hero bets</font>

Not the best card with UTG calling 2 cold on the flop but I figure I have to value bet it against lower pairs.
