30/60- KQ facing 3bet c/r on a Q-high drawy flop

[swede554]

Live 30/60. I mostly play 15/30 but there was a really soft spot playing in the 30 so I decided to sit in. Since joining the game about 45 min or so prior to this hand I'd been very aggressive due to a run of good cards but had only gone to showdown twice, winning both hands. My image is probably somewhat laggy.

8-handed. I raise in MP2 with K[img]/images/graemlins/club.gif[/img]Q[img]/images/graemlins/spade.gif[/img]. CO, button and both the blinds call.

We go to the flop 5-handed.

Flop is Q[img]/images/graemlins/heart.gif[/img]9[img]/images/graemlins/heart.gif[/img]4[img]/images/graemlins/club.gif[/img].

Blinds check to me, I bet, CO raises, button folds, SB 3bets, BB folds, I?

CO had just joined the game, no read whatsoever on him, but he bought in for 2k and I think he's a regular 30 player so I assume he's decent. SB is a good regular 30 player from what I understand but I have no prior history vs. him. I'm pretty sure he knows that I usually play 15/30 and am taking a shot in the 30/60.
