QQ vs. 3 bet, Ace on Flop

[TomBrooks]

Party 1/2 HE 6m/6h

I had the impression SB was LAP. I saw he was 57/9 over 30 hands when I checked later.

Preflop: Hero is Button with Q[img]/images/graemlins/club.gif[/img], Q[img]/images/graemlins/heart.gif[/img].
<font color="#666666">2 folds</font>, CO calls, <font color="#CC3333">Hero raises</font>, <font color="#CC3333">SB 3-bets</font>, <font color="#666666">1 fold</font>, CO calls, <font color="#CC3333">Hero caps</font>, SB calls, CO calls.

Flop: (13 SB) 3[img]/images/graemlins/diamond.gif[/img], 9[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, CO checks, Hero ...checks.

I'm new to SH, but I have seen what seems to me an inordinate number of players in the Party 1/2 game slowplaying Ax with Axx flops. I had a feeling SB might be doing that. He had 3-bet preflop and wasn't particularly pf aggressive, so I thought I would be behind more hands (AA, AK, AQs, KK) here than I would be ahead of (JJ). I didn't feel like getting checkraised which I would have folded to. I figured I would bet the turn if SB checked again or call it down UI from there if SB started betting out (unless a King came.)
