Fold to Steal from BTN

Overview

Fold to Steal from BTN is a key positional statistic used in online poker tracking software. It measures a player's tendency to fold their big blind (BB) when the button (BTN) opens the pot with a raise, typically in a situation where no one else has entered the pot. This stat is a subset of the broader "Fold to Steal" category, specific to the button's steal attempts.

How It's Calculated

The stat is calculated as: (Number of times BB folds to a BTN open) / (Total opportunities where BTN opens and BB has the chance to defend). Only hands where the pot is unopened prior to the button's raise and the big blind is the only blind remaining to act are counted. Most tracking software defaults to including hands with antes (e.g., in tournaments) or without, but it's usually tracked for both cash games and tournaments.

Typical Ranges

In modern online games, a typical Fold to Steal from BTN for a solid regular might be between 60% and 85% at low stakes, but this varies dramatically by opponent and game type. A very high percentage (e.g., >90%) indicates a player who is overly exploitable and gives up their blind too easily. A low percentage (e.g., <50%) suggests a player who defends frequently, often with a wider range, and may be difficult to steal from.

Strategic Implications

• Against a high Fold to Steal from BTN (e.g., >85%): The button should steal with a very wide range, including weak hands, since the BB is unlikely to fight back. The button can profitably raise any two cards if the fold rate is high enough.
• Against a low Fold to Steal from BTN (e.g., <60%): The button should tighten their stealing range, as the BB will defend often. The button may also consider using a larger raise size to discourage light defends or adjust post-flop strategy.
• For the BB: This stat helps identify which opponents are stealing too wide. If an opponent has a high steal attempt (Steal % from BTN) and you have a low Fold to Steal, you can profitably 3-bet or call with a range designed to counter their wide opening range.

Important Considerations

• Sample size matters: This stat can be noisy over small samples (e.g., fewer than 100 opportunities). Always consider the number of attempts.
• Game dynamics: Fold to Steal from BTN can change based on stack depth (cash vs. tournament), ante structure, and opponent tendencies. A short-stacked player may fold more often, while a deep-stacked player might defend wider.
• Adjustments: Skilled players will vary their defend frequency based on the button's range, position, and table image. The stat is a starting point, not a fixed rule.

Related Concepts

• Steal: An attempt to win the blinds by raising from late position when no one else has entered the pot.
• Defend: The act of calling or raising from the blinds to protect against a steal.
• Fold to Steal (overall): Often tracked for all positions (CO, BTN, SB), but positional breakdowns like this one are more useful.
• 3-Bet from BB: How often a player re-raises when facing a steal, which complements Fold to Steal.

This stat is a fundamental part of blind defense strategy and is widely used by poker players to exploit opponents' tendencies.
