BTN Fold to Steal

Overview

BTN Fold to Steal is a critical statistic in No-Limit Hold'em (NLHE), particularly in cash games and tournaments. It measures the percentage of times the player on the button folds when facing an open-raise from a later position, typically the cutoff (CO) or hijack (HJ), when no other players have entered the pot. This stat is part of a group of "steal defense" metrics that help evaluate a player's tendency to protect their blinds against aggressive opponents.

How It Is Calculated

BTN Fold to Steal is calculated as:

(Number of times the player folds on the [button](/term/button) facing a [steal](/term/steal) attempt) / (Total number of steal attempts faced on the button) × 100

A steal attempt is defined as an open-raise from the cutoff or hijack position (or even the button itself, though that's less common). The stat only counts situations where the player is on the button, the action folds to a late-position raiser, and the button has the opportunity to respond. It does not include situations where there are callers or re-raises before the button acts.

Typical Values and Interpretation

• Very Low (0-30%): The player rarely folds on the button, indicating aggressive defense through calls or 3-bets. This can be exploitable by stealers who adjust with tighter ranges or larger raises.
• Low (30-50%): Slightly below average. The player defends fairly often but still folds a meaningful portion of the time.
• Average (50-70%): Common for recreational or balanced players. They fold about half the time and defend the rest.
• High (70-85%): The player folds too often, making them a profitable target for frequent steals from late position. Exploitative players will increase their steal range against such opponents.
• Very High (85%+): Extreme passivity; the button is essentially forfeiting their positional advantage. Stealing from any two cards can be profitable.

Strategic Implications

• Exploiting High Fold to Steal: If an opponent has a high BTN Fold to Steal, you can profitably steal from the cutoff or hijack with a wide range, including weak hands. You should also consider larger raise sizes to apply more pressure.
• Defending Against Low Fold to Steal: When facing a button who rarely folds, you should tighten your steal range and avoid marginal hands that will be called or 3-bet frequently. You can also mix in larger raises to discourage light defenses.
• Balancing Your Own Defense: A balanced approach is to defend enough to prevent opponents from profitably stealing any two cards, but not so often that you are dominated by stronger ranges. In GTO terms, the button should defend around 50-60% of hands depending on stack sizes and raise sizing.

Related Terms

• CO Fold to Steal: Similar statistic for the cutoff position.
• BTN Raise to Steal: How often the button raises when action folds to them.
• Fold vs 3-Bet: Often considered alongside steal defense to understand overall aggression.
• Steal Attempt: A raise from late position intended to take the blinds, usually from CO or BTN.
• Defend vs Steal: The complement of Fold to Steal (i.e., 100% - Fold to Steal).

Limitations

BTN Fold to Steal can be misleading in small sample sizes. It does not account for stack depths, opponent tendencies, or table dynamics. It is most useful when combined with other stats (e.g., 3-bet %, call open %) and observed over thousands of hands. In tournaments, ICM considerations may alter optimal defense frequencies.
