Fold to 3-Bet from BTN

Definition and Calculation

Fold to 3-Bet from BTN is a metric commonly used in poker tracking software (such as Hold'em Manager or PokerTracker) to analyze how often a player defends their opening range on the button when facing a 3-bet. This metric is usually expressed as a percentage and calculated as:

Fold to 3-Bet from BTN = (Number of times the button folds when facing a 3-bet) / (Total number of times the button opens and then faces a 3-bet) × 100%

For example, if a player opens from the button 100 times, faces a 3-bet 20 times, and folds 15 of those 20 times, their Fold to 3-Bet from BTN is 75%.

Strategic Significance

• High fold rate (e.g., above 70%): Indicates the player is prone to folding on the button, allowing opponents to exploit their opens with frequent 3-bets. Opponents can 3-bet with a wide range, forcing the player to fold and win the pot immediately.
• Low fold rate (e.g., below 40%): Indicates the player rarely folds to 3-bets and tends to call or 4-bet with a wide range. Opponents should reduce light 3-bets to avoid being exploited and instead 3-bet with value hands to extract more chips.

Typical Ranges and Adjustments

• In standard games (e.g., 6-max or 9-max), most solid players have a Fold to 3-Bet from BTN between 45% and 60%.
• This metric should be evaluated with sufficient sample size: data from fewer than 50 opportunities is of limited value.
• Players should adjust their fold rate based on opponents' 3-bet frequency. If an opponent 3-bets tightly, fold more; if they 3-bet loosely, call or 4-bet more often.

Notes

• This metric only reflects behavior on the button when facing a 3-bet and does not include data from other positions.
• Fold rate is influenced by table dynamics, stack depth, player style, and other factors; it should not be viewed in isolation.
• Advanced players use this metric to develop counter-exploitation strategies, such as balancing their 4-bet range.
