A cold 4-bet is poker’s ultimate show of strength from a player who hasn’t invested a chip yet, you face an open raise and a 3-bet, then announce your presence with a massive re-raise.
In poker, a cold 4-bet occurs when a player makes the fourth bet in a sequence after witnessing both an initial raise and a 3-bet, without having any money invested in the pot. This aggressive action represents one of the strongest moves in preflop poker, typically indicating a premium holding like pocket aces, kings, or ace-king. The “cold” aspect refers to entering the pot for the first time with this significant raise.
The play requires careful consideration because you’re committing substantial chips against multiple opponents who have already shown strength. Most commonly executed from late positions or the blinds, a cold 4-bet typically sizes between 2.2x to 2.5x the 3-bet amount, creating immediate pressure on both the original raiser and the 3-bettor.
How Does Cold 4-Bet Work?
Example 1: Premium Value
You hold A♠A♣ on the button. The hijack raises to $10, the cutoff 3-bets to $35, and you cold 4-bet to $90.
This represents the classic cold 4-bet scenario, you have the best possible holding and want to build a massive pot against opponents who’ve shown strength.
Sizing Considerations
Cold 4-bet sizing typically ranges from 2.2x to 2.5x the 3-bet size. Going smaller invites too many callers, while going larger often folds out hands you want action from.
When Should You Cold 4-Bet?
- With premium hands (AA, KK, AK) when facing loose 3-bettors
- As a bluff against players who 3-bet too wide and fold to 4-bets frequently
Common Mistakes with Cold 4-Bet
Cold 4-betting too wide. Many players see a 3-bet and feel compelled to “show who’s boss” with hands like AQ or JJ, but these holdings perform poorly when called by multiple opponents.
Key Takeaway
A cold 4-bet is an extremely powerful but high-risk play that should be used sparingly. Reserve it primarily for premium hands and occasional well-timed bluffs against specific player types who over-3-bet.
