What is PFR in Poker?

PFR (Preflop Raise) is a HUD stat that shows how often a player raises before the flop, expressed as a percentage of all hands dealt. It is one of the most important numbers on a poker HUD because it separates passive players from aggressive ones. Many players confuse PFR with VPIP, but they measure different things: VPIP counts every time a player voluntarily puts money in the pot (calls or raises), while PFR counts only raises. A player who calls a lot but rarely raises will have a high VPIP and a low PFR, revealing a passive style. A player who raises often will have a PFR close to their VPIP, indicating aggression.

How this stat is counted

PFR is calculated by dividing the number of hands in which a player made a raise before the flop by the total number of hands they were dealt, then multiplying by 100. For example, if a player raises preflop in 15 out of 100 hands, their PFR is 15%. The stat includes raises made as the first action (open-raises) and raises over another player's raise (3-bets and 4-bets). It does not include calls, folds, or checks. It also does not include raises made after the flop, since those are tracked by other stats like Aggression Factor (AF) or Flop C-bet.

Sample size matters. A PFR over a small number of hands, say 50, is noisy and can swing wildly. You need at least a few hundred hands to trust the number. With 1,000 hands, the stat becomes more reliable, but even then, it is an average that hides situational differences. For example, a player might have a PFR of 20% overall but raise much wider on the button than from early position. The overall number is a starting point, not the whole story.

How to use PFR in your decisions

PFR helps you classify opponents and adjust your strategy. A common way to read it is to compare it to VPIP. The gap between VPIP and PFR tells you how often a player calls instead of raising. A tight-aggressive (TAG) player might have a VPIP of 15% and a PFR of 12%, meaning they raise most of the hands they play. A loose-passive player might have a VPIP of 30% and a PFR of 5%, meaning they call a lot but rarely raise. You can use this to decide whether to isolate, value bet, or bluff.

Here is a rough guide to interpreting PFR values (these are general ranges, not exact targets):

These bands are typical for 6-max cash games, but they shift with table dynamics. In a full-ring game, players tend to have lower PFRs because they play fewer hands from early position. In heads-up, PFRs are much higher, often above 40%.

When not to use PFR

PFR is a preflop stat, so it tells you nothing about postflop tendencies. A player with a high PFR might be a terrible postflop player, while a low-PFR player might be a strong postflop player. Do not use PFR to decide whether to call a river bet or whether to bluff on the turn. For those decisions, look at stats like Aggression Frequency, C-bet, or WTSD (Went to Showdown).

Also, PFR is less useful in tournaments with deep stacks and antes, where players may raise more or less depending on stack sizes and payout pressure. In short-handed or dynamic games, the stat can be misleading if you do not consider position. A player with a 15% PFR might raise 25% on the button but only 8% from early position. If you only look at the overall number, you might misjudge their range in a specific spot.

Leaks on this HUD number

• Overvaluing small samples: A PFR of 20% over 30 hands is meaningless. Wait for at least 100 hands, and ideally 500+, before making assumptions.
• Ignoring the VPIP-PFR gap: A player with VPIP 25% and PFR 20% is aggressive, but a player with VPIP 25% and PFR 5% is passive. The gap is the key to reading their style.
• Using PFR as a postflop guide: PFR does not predict postflop aggression. A high-PFR player might check-fold too much, while a low-PFR player might be a calling station. Use other stats for postflop decisions.
• Assuming PFR equals hand strength: A high PFR does not mean a player only raises premium hands; they might be raising a wide range. Conversely, a low PFR might be raising a tight range, but that range is strong. Adjust your calling range accordingly.

Next decision after reading PFR

When you see a player's PFR, your next decision is to adjust your preflop strategy against them. If their PFR is high, you should tighten your calling range and consider 3-betting more often with hands that play well against a wide range. If their PFR is low, you can fold more to their raises and avoid bluffing them, since they are likely to have a strong hand. The key is to combine PFR with VPIP and position to build a profile, then act on that profile in the current hand.

Frequently asked questions

What is a good PFR in poker?

A good PFR depends on the game format and your strategy. In 6-max cash games, a typical TAG player might have a PFR around a typical fraction, while a LAG might have 20% or more. In full-ring, lower PFRs are common. There is no single "good" number; it is about consistency and matching your VPIP.

How is PFR different from VPIP?

PFR counts only preflop raises, while VPIP counts any voluntary money put in the pot, including calls and raises. A player who calls a lot but rarely raises will have a high VPIP and a low PFR, indicating a passive style.

What does a high PFR mean in poker?

A high PFR means a player raises a large percentage of hands before the flop. This usually indicates an aggressive style, but it could also mean they are raising too wide and are exploitable. You can counter by 3-betting more often with strong hands.

How many hands do you need to trust PFR?

You need at least a few hundred hands to get a reliable PFR. With fewer than 100 hands, the stat is too noisy to be useful. The more hands you have, the more accurate the number becomes, but always consider the context of position and game type.

Can PFR be used in tournaments?

Yes, PFR is useful in tournaments, but it can be affected by stack sizes and blind levels. In tournaments, players may adjust their raising ranges based on their stack and the payout structure, so the stat may not be as stable as in cash games.
