A cooler is a hand where two players both have very strong hands, and the one with the slightly weaker hand loses a big pot. Neither player made a mistake: given the cards, almost anyone would have put all their money in.
Classic cooler examples
- KK vs AA preflop: kings are the second-best starting hand, so folding them is almost never right. AA wins about 81% of the time. See AA vs KK odds.
- Set over set: you flop a set of sevens, your opponent flops a set of jacks.
- Flush over flush: your king-high flush runs into the ace-high flush.
- Full house vs quads.
Cooler vs bad beat
A bad beat is when you get your money in as a big favorite and lose because your opponent hits a lucky card — for example, AA losing to 72 offsuit. In a cooler, the winner usually was ahead or close all along; in a bad beat, the loser was ahead when the money went in.
How often do coolers happen?
If you hold KK at a full table, the chance that one of eight opponents holds AA is about 4%. When two pocket pairs see a flop, both flop a set roughly 1% of the time. Coolers are rare in any one hand but common over thousands of hands.
How to handle a cooler
Accept it and move on. Coolers are part of the game’s variance, not a sign you played badly. Letting one lead to tilt costs far more than the pot itself. More terms in the poker glossary.
