BTN PFR
BTN PFR
BTN PFR refers to the Preflop Raise percentage from the button position, a poker statistic measuring how often a player raises preflop when seated on the button.
Meaning and Calculation
BTN PFR (Button Preflop Raise) is a positional poker statistic that tracks how frequently a player raises before the flop when they are in the button position. It is typically expressed as a percentage and is derived from hand history data in tracking software such as Hold'em Manager or PokerTracker. The calculation is: (Number of times the player raised preflop on the button) / (Number of opportunities to raise preflop on the button).
Importance in Strategy
BTN PFR is a key stat because the button is the most advantageous postflop position. Players generally have a wider raising range from the button compared to early positions. A high BTN PFR (e.g., above 50% in full-ring or 60% in 6-max) indicates an aggressive player who frequently exploits the positional advantage. A low BTN PFR (e.g., below 20%) suggests a tight player who only raises strong hands even in position.
Typical Ranges
- Tight-aggressive (TAG): 25–35% in 6-max, 15–25% in full-ring.
- Loose-aggressive (LAG): 40–55% in 6-max, 30–40% in full-ring.
- Very tight (nit): 10–15% in 6-max, 5–10% in full-ring.
These ranges vary by stake, player pool, and game type (cash vs. tournament).
Relationship to Other Stats
- Overall PFR: BTN PFR is a component of a player's total PFR. A large discrepancy between overall PFR and BTN PFR often indicates a positionally aware player.
- RFI (Raise First In): BTN PFR is essentially the same as BTN RFI when no one has entered the pot. However, if there are limpers, BTN PFR can include raises over limpers, so it's slightly different.
- VPIP: BTN VPIP (Voluntarily Put Money In Pot) complements BTN PFR. The gap between BTN VPIP and BTN PFR shows how often the player limps or calls raises on the button.
Usage in Analysis
Tracking software allows players to filter stats by position. When studying opponents, BTN PFR helps determine their button stealing tendencies. A high BTN PFR suggests they will raise many hands, so you can defend your blinds more light. A low BTN PFR indicates they are selective, allowing you to apply more pressure.
Limitations
Sample size matters. BTN PFR can be volatile over small numbers of hands. For reliable analysis, at least 100–200 button opportunities are recommended. Also, BTN PFR does not account for table dynamics, stack sizes, or opponent tendencies; it is just one piece of the puzzle.
