QQ !

Okay. Giving away free cards in your situation is not terrible. You could be beaten badly or they could be drawing quite live to a flush draw, and you aren't gonna be getting them out.

I still like a bet though. Everyone might fold, and you don't want to give free cards to some Kx. If raised, I might peel for the backdoor flush and Q outs. It's better that you have the Q diamonds, so you have a full 2 outs for the Qs. Given the times that he c/r you with only a flush draw, you still have a decent equity edge, which I think makes it a call.

Given the way you played it, turn and river look good. Next time bet the flop.
