AQo vs a preflop LAG

[IPSC]

UTG has only played 4 hands at the table.

UTG-2 is more than likely a preflop LAG.

VPIP 67%, PFR 13%, AF 1.31, WTSD 59, Won $ SD 60%.

**Only 24 hands on this player when this hand was played**

I know this sample is very small, but I think I can safely use his VPIP and PFR stats to help me play this hand.

Preflop: Hero is Button with Q[img]/images/graemlins/club.gif[/img], A[img]/images/graemlins/spade.gif[/img].
UTG calls, <font color="#666666">1 fold</font>, <font color="#CC3333">UTG+2 raises</font>, <font color="#666666">4 folds</font>, <font color="#CC3333">Hero 3-bets</font>, <font color="#666666">2 folds</font>, UTG calls, UTG+2 calls.

I feel at this point my AQ compares favorably to the hands UTG-2 is playing. I want to encourage the blinds and the limping UTG to fold.

Flop: (10.50 SB) K[img]/images/graemlins/diamond.gif[/img], 4[img]/images/graemlins/heart.gif[/img], 9[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
UTG checks, UTG+2 checks, <font color="#CC3333">Hero bets</font>, UTG calls, UTG+2 calls.

I think this flop bet is marginal since I have no backdoors and one my overcards could be no good, but the pot is 10.5 SB, a bet may improve my winning chances, and I may be able to get free card.

Flop didn't fold anybody. I'm positive I'll have to improve to win, doubt I can fold anyone, and I'm drawing very thin so I think this is an obvious free card.

Well I luckily improve. Is this the correct spot to make an overcall? Overcall section has me pretty confused in SSH. Am I good more than 10% of the time here?

Final Pot: 9.75 BB
