4Bet Sizing: Master Your Range in 2024
The art of 4Bet sizing is a crucial component of modern poker strategy, impacting everything from pot control to opponent exploitation. This guide dives deep into navigating the complexities of 4Bet sizing in 2024, offering insights for players of all skill levels. Understanding how and why to adjust your 4Bet sizes is paramount to maximizing value and applying effective pressure.
Beyond Value vs. Bluff: Why Sizing Matters
For too long, many players viewed the 4Bet as a purely value-driven play or a simple bluff. However, size drastically alters the dynamics of the hand. A larger 4Bet can induce folds from a wider range, while a smaller 4Bet encourages calls, setting up favorable post-flop scenarios. Proper sizing impacts your 4bet range and ultimately, your win rate.
The 2024 Landscape – Increased Aggression & Solver Trends
The 2024 poker climate is marked by an increase in preflop aggression and a wider adoption of solver-based strategies. Players are more comfortable 3Betting and 4Betting light, making informed 4Bet sizing even more vital. Ignoring these trends can leave you vulnerable to exploitation.
Understanding 4Bet Ranges – A Quick Recap
A solid foundation in range construction is essential before diving into sizing. Your 4bet range should be carefully considered based on your position, opponent tendencies, and the board texture you anticipate.

Polarized 4Betting Ranges – Integrating Bluffs
Polarized ranges combine top-tier value hands with strategic bluffs like A5s, A4s, or K2s. These bluffs contribute to balance and make it harder for opponents to read your hand. This often connects to the use of 4*4bet as a psychological play.
Merged 4Betting Ranges – Situational Adjustments & Weaknesses
Merging ranges involve adding some medium-strength hands to your 4Bet range. This is often used against passive opponents who rarely fold. However, it can make you more vulnerable to aggressive 5Bets.
