CO Preflop 4-Bet Pot
CO Preflop 4-Bet Pot
A pot where the player in the cutoff position makes a fourth bet (4-bet) before the flop, typically indicating a strong hand or a calculated bluff after an initial raise and a 3-bet.
Overview
In Texas Hold'em, a "CO Preflop 4-Bet Pot" occurs when the player in the cutoff (CO) makes a 4-bet preflop. This action follows an initial raise (usually from early or middle position) and a 3-bet from another player (often from late position or the blinds). The CO is in a favorable seat, acting after most players but before the button and blinds, giving them positional advantage postflop.
Strategic Meaning
The CO's 4-bet range is polarized or merged depending on opponent tendencies. Typically, it includes premium hands like AA and KK, sometimes AKs, and occasionally suited aces or small pairs as bluffs. The size is usually around 2.2x to 2.5x the 3-bet, adjusted for stack depths. Because the CO has position, they can 4-bet lighter than early positions, knowing that if called, they have postflop advantage.
Key Factors
- Stack Sizes: Effective stacks influence 4-bet ranges. Deep stacks allow more speculative 4-bets (e.g., small pairs), while shallow stacks force tighter ranges (value-only).
- Opponent's 3-Bet Tendencies: Against a loose 3-bettor, CO can 4-bet wider for value; against a tight 3-bettor, bluffing becomes dangerous.
- Position: Being in the CO provides leverage—villain in the blinds may 5-bet shove light, but the CO's range remains strong.
Common Mistakes
- 4-betting too frequently with marginal hands (like KQo) out of position postflop? Actually, CO has position, but still, light 4-bets can be exploited by 5-bets.
- Failing to balance: If CO only 4-bets AA/KK, observant opponents can fold cheaply or 5-bet bluff profitably.
- Ignoring table dynamics: In multi-way pots, the CO should be more selective as the 3-bet range from earlier positions is tighter.
Example
A typical scenario: UTG raises to 3bb, MP calls, button 3-bets to 12bb. The CO now faces a decision: 4-bet to 26bb with a strong hand, forcing UTG/MP out and isolating the button. This creates a CO Preflop 4-Bet Pot, heads-up with position.
Conclusion
The "CO Preflop 4-Bet Pot" is a common but nuanced situation. Proper range construction and sizing, adjusted to opponents and stacks, can turn this spot into a profitable one for the cutoff player.
