QQ faces preflop heat OOP and flop comes safe... against unknown

[kelvinsense]

This isn't really a "safe" board since you flat-called preflop, you don't really know where you are. It looks like he has KK-AA here.

I would definitely 3-bet to 12 preflop, and probably fold to a 4bet.

as played c/f the flop. after flat-calling preflop you really don't want to continue with QQ unless you hit a set. (against an unknown)
