A loose cutoff opens to 600, the button just calls, and the small blind folds. You're in the big blind with A♥Q♥.

Loose opener, a flat-caller behind, and you hold A♥Q♥ in the BB. Best?

WhyThree-bet squeeze. The opener is loose and the caller's flat caps him at a hand too weak to four-bet - both are squeezed. A large three-bet takes it down often, and A-Q suited has real equity when called. Flatting invites a multiway pot out of position with a hand that wants to be heads-up.
What happensYou squeeze to 2,600 (13 BB); both fold.  You scoop it pre-flop.
A raiser plus a flat-caller is the classic squeeze setup - a big three-bet from the blind put both in a bad spot and took the pot before the flop.

When a raise is flatted in front of you, squeeze with a large three-bet - the caller is capped and the raiser is often stealing, so both fold too much.
