4Bet from CO

4Bet from CO

Basic Concepts

4Bet refers to the fourth bet preflop (in order: small blind or big blind bet → raise → 3Bet → 4Bet). It is a powerful re-raise in Texas Hold'em. When a player in the CO (Cut Off, the position immediately to the right of the dealer) makes a 4Bet, it is called a "4Bet from CO".

Position Advantage and Strategy

CO is one of the most advantageous positions preflop, second only to the button (BTN). Since CO has a positional advantage over players other than the button postflop, its 4Bet range can be wider than early positions. Typical scenarios are as follows:

• Value 4Bet: Holding strong hands (such as AA, KK, AKs, etc.), aiming to build the pot with a 4Bet while forcing opponents to fold or call.
• Bluff 4Bet: When observing that the opponent's 3Bet range is wide, you can use medium–weak hands (such as A5s, KQo, etc.) to make a 4Bet bluff, using fold equity to take down the pot directly.

Influencing Factors

• Opponent Tendencies: If the opponent 3bets frequently and has a high fold rate to 4Bets, you can increase the bluff ratio; otherwise, you should focus on value.
• Effective Stack Depth: When stacks are deep (e.g., over 100BB), opponents may call or 5Bet after a 4Bet, requiring more careful hand selection.
• Positional Relationships: When CO faces a 3Bet from BTN or the blinds, a 4Bet is more effective because the ranges of subsequent players may be weaker.

Common Misconceptions

Beginners often mistakenly believe that a 4Bet only represents a super strong hand, but in reality, it can be mixed with bluffs in appropriate situations. However, excessive bluffing can lead to frequent 5Bet counterattacks from opponents. Generally, the 4Bet range from CO should balance value and bluffs to maintain unpredictability.
