Cooler
Also known as: coolered, got coolered
A big pot where both players play correctly but one holds a strong hand that's dominated — unavoidable, not a mistake.
A cooler is when two strong hands collide and the money goes in correctly — set over set, nut flush versus the second nuts, overpair into a set, AA versus KK preflop. Neither player misplayed; the deck simply dealt a confrontation where the loser was always going to lose a stack. Coolers are a cost of doing business, not a leak.
The key distinction is from a bad beat: in a bad beat you were ahead and got outdrawn by an underdog. In a cooler you were behind (or flipping) the whole time and got the money in for the right reasons. "I got coolered" should mean "I made the standard play with a hand I'm supposed to stack off, and ran into the top of the range" — it is not an excuse for getting it in bad.
Mentally, separate the two: bad beats and coolers are variance, not errors, so they shouldn't trigger tilt or a strategy change. The honest review question is whether it was truly a cooler or whether you can find a fold — many "coolers" hide a leak the loser doesn't want to see.
