Fold to 3-Bet

Overview

Fold to 3-Bet (F3B) is a key poker tracking statistic, especially in no-limit hold'em cash games and tournaments. It represents the percentage of times a player folds after raising first (or sometimes after open-limping) when faced with a 3-bet. For example, if a player raises preflop, then an opponent re-raises (3-bets), and the original raiser folds, that counts as a fold to 3-bet.

Calculation

F3B is calculated as: (Number of folds to a 3-bet) / (Total number of times facing a 3-bet after opening) × 100. Most tracking software (e.g., PokerTracker, Hold'em Manager) calculate it automatically. The denominator excludes hands where the player faced a 3-bet but also had other actions (e.g., being all-in or facing a 4-bet).

Importance

F3B is a crucial indicator of a player's aggression and hand strength threshold. A very high F3B (e.g., >65%) suggests a player is opening too wide and folding too often to re-raises, making them exploitable by frequent 3-bettors. Conversely, a very low F3B (e.g., <40%) indicates a player is defending too many raises, potentially with weak hands, which can be targeted by value-heavy 3-bets.

Strategic Use

• Against tight players: If an opponent has a low F3B (defends often), you should 3-bet them with a polarized range of strong hands and some bluffs, since they will call or 4-bet frequently. Avoid 3-bet bluffing against high F3B opponents who fold too much – instead, increase your 3-bet value range and consider stealing with wide opens.
• Adjusting your own F3B: Optimal F3B depends on game type, stack sizes, and opponent tendencies. In general, a balanced strategy might target an F3B around 45-55% in cash games, but this varies. Against aggressive 3-bettors, you might lower your F3B (defend more) to discourage light 3-bets. Against passive opponents, you can afford a higher F3B.

Limitations

F3B alone doesn't capture the full picture. For instance, a player with a high F3B might be folding weak hands but calling/4-betting with strong holdings, which is fine. Also, sample size matters – F3B over a few hundred hands can be noisy. Always combine with other stats like 3-Bet%, Raise First In, and postflop aggression.

Related Concepts

• 3-Bet: A re-raise after an initial raise.
• Raise First In (RFI): The percentage of times a player raises when no one else has entered the pot.
• 4-Bet: A re-raise after a 3-bet; F3B is the step before deciding to 4-bet or call.

Conclusion

Fold to 3-Bet is an essential metric for understanding preflop dynamics. By monitoring and adjusting your own F3B and exploiting opponents' tendencies, you can improve your profitability and reduce exploitable leaks.
