CO 25bb 3-Bet Jam
CO 25bb 3-Bet Jam
CO 25bb 3-Bet Jam Refers to an aggressive play where the player in the cutoff CO with approximately 25 big blinds re-raises 3-bets an opponent's raise and then shoves all-in.
Overview
CO 25bb 3-Bet Jam is a common short-stack aggressive strategy in Texas Hold'em, typically executed by the cutoff player in tournaments or deep-stacked cash games. The term consists of three parts: position (CO), stack depth (25bb), and action (3-Bet Jam), emphasizing a full-range or exploitative all-in under specific stack sizes to leverage positional advantage.
Principles
- Stack Factor: 25bb is a medium-short stack. At this depth, the pot becomes relatively large after a 3-bet, so shoving puts tremendous pressure on opponents while keeping your own fold equity low.
- Positional Advantage: The CO has a positional advantage over the blinds post-flop. Shoving avoids complex post-flop decisions and maximizes fold equity.
- Range Polarization: Typically consists of strong hands (e.g., TT+, AQ+) and a few bluff hands (e.g., small pairs, suited connectors) to balance value and bluffs.
Execution Conditions
- Opponent's raising range is wide and they have a high fold-to-3-bet percentage.
- Blind players are passive and unlikely to call or re-raise.
- Your own stack is around 22-28bb. Deeper stacks reduce shoving efficiency, while shorter stacks require tightening your calling range.
Risks and Adjustments
- If opponents call frequently, reduce the bluff proportion; if they 4-bet often, tighten your range.
- In late tournament stages, consider ICM pressure and avoid overusing the move when elimination risk is high.
Example (Typical Scenario)
Assume blinds 100/200, CO stack 5000 (25bb), BTN raises to 450. CO holds A♠K♠ and shoves all-in for 5000, forcing BTN to fold or call with a weak hand.
