Pocket Q's with trips on the board

[bags]

Only my fifth hand at the table, but in general it seemed a bit laggy as I watched a couple of orbits before sitting.

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

I think I made the right move in EP calling the re-raise, but looking back at the hand I wonder if I should have tried to isolate the button by capping as I had the best read on him and knew he was even more of a LAG than the rest of the table.

Flop: (10.80 SB) 3[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img], 3[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, CO calls, Button folds.

The A scared me so I bet to get some information. Seeing the call made me a bit more confident CO didn't have it.

Turn: (6.40 BB) 3[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets</font>, <font color="#CC3333">CO raises</font>, Hero calls.

Was he slow-playing me by not re-raising on the last street? I felt the odds were enough to call his re-raise at this point regardless, but I was considering a check/fold on the river as a result of his play on this street.

River: (10.40 BB) 8[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, CO checks.

Final Pot: 10.40 BB
