A QQ hand

50 NL, 6 handed. everybody is playing pretty typical straightforward poker, except that they chase too much. I am playing moderately loose, and have been 3-betting light for about 1/2 an hour.

Effective stacks are ~110 BB.

UTG raises to 1.75, button calls, SB calls, I raise from the BB to 8 w/ :Qc: :Qh:
UTG calls, SB calls.

pot: ~25
Flop: 3 rags with 2 spades. SB checks, I bet 20, UTG folds, SB calls.

pot: ~65
Turn: another non-spade rag. SB checks, I push for about 25, he calls.

I have 2 reasons for posting this hand. First, I would like to ask if I overplayed my hand here at all. I have a bad habit of overplaying QQ (and JJ to a lesser extent). I assumed SB was on the draw here, probably with the :as:.

The second reason (which will give away opps hand) was to show the importance of reraising AK preflop. SB had :As::ks:, and lost his stack on the hand. If he had put in a reraise pf, I doubt that I would have 4-bet him, and probably would have been a lot more cautious postflop, allowing the SB to draw for much cheaper. This would have been bad for me, but very good for him. If he had bet the flop hard, I may have even found a fold.

You played the hand fine.
