MP Fold to 3-Bet

MP Fold to 3-Bet

MP Fold to 3-Bet is a poker statistic that measures how often a player in middle position (typically seats 3-5 at a 9-handed table) folds their opening raise when confronted with a 3-bet. It is a key indicator of a player's post-flop tendencies and ranges from that position.

Why It Matters

In modern poker, middle position is a critical juncture. Players open from MP with a fairly wide range, often including hands like suited connectors, medium pairs, and broadways. How often they fold to a 3-bet directly affects their profitability against aggressive opponents. A high fold rate (e.g., above 60%) suggests the player is exploitable: they are likely folding too much to 3-bets, allowing observant opponents to profit by 3-betting light. Conversely, a low fold rate (e.g., below 40%) indicates the player is sticky, potentially over-calling or 4-betting too frequently, which can be exploited by tighter 3-betting ranges.

Typical Ranges

• Tight/Passive: >60% fold to 3-bet. These players often open with a narrow range and give up easily to aggression. Exploit by 3-betting them frequently with a wide range.
• Balanced: 40-60% fold to 3-bet. This is generally considered healthy. The player is selective about continuing but not overly exploitable.
• Loose/Aggressive: <40% fold to 3-bet. These players defend their opens aggressively, often calling or 4-betting. Exploit by 3-betting them with a stronger range and value-heavy hands.

Example Scenario

Consider a 9-handed no-limit hold'em cash game. A player in MP opens to 3 big blinds. The player in the cutoff (CO) 3-bets to 9 big blinds. If the MP player folds every time in this spot, their MP Fold to 3-Bet would be 100% in that sample. Over thousands of hands, a regular might show an MP Fold to 3-Bet of 55%, meaning they continue with only 45% of their opening range.

Usage in Game Theory Optimal (GTO) Play

GTO strategies suggest that in MP, the ideal fold-to-3-bet percentage depends on stack sizes, the specific opening range, and the 3-bet size. However, a common GTO frequency for a typical 100 big blind stack is around 50-55%. Deviating significantly from this can be exploited. For example, if you fold too often, opponents can profit by 3-betting any two cards. If you call too often, they can tighten their 3-bets for value.

How to Adjust Your Own Game

• If your MP Fold to 3-Bet is too high, consider calling or 4-betting more with hands that have good equity against aggressive 3-bets, such as medium pairs, suited aces, and strong suited connectors.
• If it is too low, you may be playing too many marginal hands out of position. Try folding more hands like low suited connectors or weak offsuit broadways when facing a 3-bet.

Related Statistics

• UTG Fold to 3-Bet and CO Fold to 3-Bet are analogous stats for other positions.
• 3-Bet% measures how often a player makes a 3-bet, which is the other side of the coin.
• Fold to 4-Bet tracks how often a player folds after 3-betting and facing a 4-bet.

In summary, MP Fold to 3-Bet is a vital stat for both analyzing opponents and refining your own strategy. It reveals how a player handles aggression from later positions and provides clear exploitation paths.
