Fold to Steal from BB

Overview

Fold to Steal from BB (often abbreviated as "Fold to Steal" or "FTS") is a poker statistic used primarily in No-Limit Hold'em. It measures how often a player in the big blind (BB) folds when facing a raise from a late-position player—typically from the cutoff, hijack, or button—who is attempting to steal the blinds. This metric is a key component of a player's overall blind defense strategy.

Usage in HUDs

In tracking software like PokerTracker or Hold'em Manager, Fold to Steal is displayed as a percentage. For example, a player with a Fold to Steal of 70% means they fold 70% of the time when they are in the BB and face a steal raise. The statistic usually excludes situations where the big blind has already called or folded before the steal, and it applies only to the initial raise, not re-raises or subsequent actions. Many HUDs also break this down by position (e.g., vs. button, vs. cutoff).

Typical Values

Average Fold to Steal values vary by stake and player style, but general guidelines:

• Tight/passive players: 70-80% or higher
• Aggressive/regs: 40-60%
• Loose/defensive players: 30-50%

A very low Fold to Steal (e.g., below 40%) indicates that the player defends their big blind frequently, often by calling or 3-betting. A very high Fold to Steal (e.g., above 80%) suggests the player is exploitable and losing money in the BB by giving up too often.

Strategic Importance

Defending the big blind is crucial because the BB already has a forced investment. To be profitable in the long run, a player must defend enough to prevent opponents from stealing profitably. Game theory optimal (GTO) strategy suggests that a player should defend roughly 40-50% of hands when facing a standard-sized steal (e.g., 2.5x-3x BB), depending on the opponent's range. However, in practice, many players under-defend or over-defend based on opponent tendencies.

A high Fold to Steal can be exploited by opponents who will steal more frequently. Conversely, a low Fold to Steal can be exploited by opponents who 3-bet or tighten their stealing range. Adjusting Fold to Steal based on opponent and stack sizes is a key skill.

Factors Influencing Fold to Steal

• Raise size: Larger raises force the BB to defend less often.
• Stack sizes: Shorter stacks may require tighter defense; deeper stacks allow more speculative calls.
• Opponent tendencies: Against a loose aggressor, defending wider is often correct; against a tight stealer, folding more is fine.
• Position of stealer: Defending vs. button is generally wider than vs. cutoff due to range differences.
• Post-flop skill: Players who are strong post-flop can defend more hands profitably.

Conclusion

Fold to Steal from BB is a fundamental statistic for assessing a player's blind defense. Understanding and adjusting this number is essential for both exploiting opponents and plugging leaks in one's own game. A balanced approach, combined with awareness of opponent tendencies and game dynamics, leads to optimal play from the big blind.
