Cold 4-bet
Also: cold four-bet, cold 4bet
A 4-bet made by a player who has not yet put money in the pot — someone behind both the opener and the 3-bettor. It represents an extremely strong hand because the player is up against two ranges that have already shown strength.
Example. Hijack opens, cutoff 3-bets, and the big blind cold 4-bets with pocket kings.
Cold 4-bets are made almost exclusively with aces, kings and sometimes ace-king or queens, plus the occasional blocker bluff by very aggressive players. Facing one, most 3-bettors fold everything except the very top of their range.
