QQ's in the BB, how should I play the flop?

[AceHigh]

Playing 2/4 on PP, I'm dealt Q [img]/forums/images/icons/diamond.gif[/img] Q [img]/forums/images/icons/club.gif[/img] in the BB. This table is a little more passive and a little looser than normal, probably cause of the hand promotion jackpot. 5 people limp in, the small blind folds and I raise out of the BB, everybody calls. Anybody just check here?

Flop is:
7 [img]/forums/images/icons/club.gif[/img] K [img]/forums/images/icons/heart.gif[/img] T [img]/forums/images/icons/spade.gif[/img]

OK decision time here, who bets and who checks on the flop?

I bet out, but I think that might be too aggressive, someone is likely to have a K here, correct?

I'll post results later.
