SB Fold to 3-Bet

SB Fold to 3-Bet

Overview

SB Fold to 3-Bet is a key statistic in Texas Hold'em that measures the preflop defensive tendencies of a player in the small blind position. It is commonly used as a HUD (heads-up display) stat. This number reflects the frequency with which a player folds their hand after raising from the small blind and facing a 3-bet.

Strategic Significance

The small blind is one of the worst positions preflop because it is always out of position postflop. Therefore, a small blind's raising range is typically tight. However, when facing a 3-bet, many hands that could normally call (such as medium pairs, suited connectors) become difficult to play profitably due to positional disadvantage. A reasonable fold percentage helps players avoid committing too many chips while out of position.

Typical Ranges and Adjustments

• High Fold Rate (approximately 70% or more): Indicates the player is very cautious facing a 3-bet, typically continuing only with strong hands (such as JJ+, AK). Opponents can exploit this tendency by 3-betting frequently.
• Low Fold Rate (approximately 50% or less): Means the player defends with a wider range, including some speculative hands. However, over-defending can lead to postflop losses while out of position.
• Balanced Value: In GTO solvers, the small blind's fold to 3-bet is usually around 60%-70%, depending on stack depth and 3-bet sizing.

Notes

This stat should be interpreted alongside the opponent's 3-bet frequency and overall playing style. For example, if an opponent 3-bets very wide, the small blind should lower their fold rate accordingly; if the opponent only 3-bets with strong hands, the fold rate can be higher. Additionally, stack depth also affects decisions: with deep stacks, speculative hands become more valuable, so the fold rate can be reduced; with short stacks, the tendency is more toward shoving or folding.

Summary

SB Fold to 3-Bet is an important metric for evaluating a small blind player's defensive tendencies and a key reference for exploitative adjustments. A reasonable fold rate should be adjusted based on positional disadvantage, opponent tendencies, and dynamic balance.
