面对中间位置4-Bet的弃牌率（Fold to 4-Bet from MP）

Overview

[Fold to 4-Bet] from [MP] (fold to a 4-bet from middle position) is a poker [HUD] statistic used to measure a player's tendency to fold when facing a [4-Bet] from [MP]. It is expressed as a percentage, calculated as: number of folds to a 4-bet from MP divided by total times facing a 4-bet from MP.

Importance

This indicator helps analyze an opponent's aggression or fold tendency when facing a re-raise. A high [Fold to 4-Bet] from MP (e.g., >70%) suggests the player is easily scared by a 4-bet from MP, often indicating a wide [3-bet range] with many bluffs, or weak defense against 4-bets. Conversely, a low value (<40%) shows the player tends to resist, likely holding strong hands or having a high bluff-catching tendency.

Typical Ranges and Interpretation

• High (>65%): The player often folds to MP's 4-bet after 3-betting. This means their [3-bet range] may contain many bluffs or weak hands, or they respect MP's 4-bet range significantly. As an opponent, consider exploiting by [4-bet bluffing] with a wider range.
• Medium (40%–65%): A balanced range typical of a regular player.
• Low (<40%): The player tends to continue, usually holding strong hands or showing high resistance. Against such players, [4-bet bluffing] is less effective; prefer value 4-bets.

Influencing Factors

• [3-Bet] Range: If a player's 3-bet range is wide, their [Fold] to 4-Bet from MP is often high because weak hands cannot withstand a re-raise.
• Opponent Type: Tight-aggressive players ([TAG]) typically have low values, while loose-aggressive players ([LAG]) may have high or medium values.
• Position Dynamics: MP's 4-bet range is generally strong (since MP opened and then 4-bet after a 3-bet), so many players fold reasonably.
• [Stack Depth]: With deep stacks, players may prefer to call or [5-Bet] with speculative hands like small pairs or [suited connectors], rather than fold; with shallow stacks, fold rates increase.

Usage Tips

In practice, combine this stat with others (e.g., 3-bet frequency, 4-bet range, opponent's RFI) for a comprehensive assessment. Relying solely on this indicator can lead to misjudgment due to statistical variance with small sample sizes. It is recommended to have at least 100 hands facing a 4-bet from MP before referencing this data.
