Squeeze
A re-raise after one player raises and others call. The callers are trapped between you and the raiser.
Blinds are 1/2. UTG opens to 6 with pocket nines, hoping for a quiet pot. Middle position calls with A-T suited, planning to see a cheap flop and use position later. It folds to the button, who wakes up with Q-Q and reraises to 22. Now UTG faces a raise almost four times his open, with a live caller still behind him. Middle position is worse off: he put chips in with a speculative hand and now has to call real money against two players, one of whom just repped a big hand. Both fold. The button takes the blinds, the open, and the call without a flop.
The squeeze works because of dead money and weak ranges. A standard open often isn't a monster, and a flat call behind it is rarely premium either, since most players three-bet aces and kings instead of just calling. A modest open plus a passive call is the spot where a big reraise folds out two hands instead of one. That's why you see it against loose opens with callers, not against a tight UTG raise.
The mistake is treating it as a free bluff with any two cards. A squeeze that gets called leaves you out of position against a real hand. So it needs two things: a size big enough to actually fold people out, and a holding that can stand a call.
