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?

WhyThe flat-caller can't have a premium - he'd have reraised it - so he's capped, and the loose opener is often light; a big three-bet leans on both at once. Size it up because you want folds, and A-Q suited still carries real equity the times someone continues. Calling drags you multiway and out of position with a hand that wants to be heads-up.
What happensYou make it 2,600 (13 BB) and both fold. The squeeze scoops a pot neither opponent was strong enough to defend - and you never had to navigate a flop out of position.
Opener plus flat-caller is the textbook squeeze - a big reraise from the blind put two capped ranges to a tough decision and took it down. You don't need a monster; you need the setup.

A raise that's been flat-called is a squeeze setup - the caller is capped below a reraising hand and the opener is often stealing, so a large three-bet makes both fold far too often.
