Poker Stats Glossary
preflop Stats
VPIP
VPIP (Voluntarily Put money In Pot) measures how often you voluntarily invest chips preflop — by calling, raising, or re-raising. Posting blinds does not count. A high VPIP indicates a loose style; a low VPIP indicates a tight style.
PFR
PFR (Preflop Raise) tracks how often you raise or re-raise before the flop. It is always a subset of VPIP — you cannot raise without putting money in. The gap between VPIP and PFR reveals how often you enter the pot by just calling (cold-call or limp).
Open Raise
Open Raise measures how often you raise when the action folds to you preflop and nobody has entered the pot yet. Unlike PFR, which includes all preflop raises (3-bets, squeezes, etc.), Open Raise only counts raises when you are the first voluntary actor.
Limp
Limp measures how often you enter the pot by just calling the big blind when action folds to you preflop and nobody has raised yet (open limp). It is only counted when you have the opportunity to open — i.e. all players before you have folded.
Overlimp
Overlimp tracks how often you limp behind after one or more players have already limped in. Unlike an open limp, an overlimp occurs when there is already dead money from other limpers but no raise yet.
Call vs Open
Call vs Open (Cold Call) measures how often you call a preflop open raise without having previously put money in the pot (excluding blinds). A high cold-call rate can indicate a passive preflop approach.
3-Bet
3-Bet measures how often you re-raise after a player has opened with a raise preflop. The name comes from the fact that the blinds are the first bet, the open raise is the second, and your re-raise is the third.
Squeeze
Squeeze measures how often you re-raise preflop when there has been an open raise and at least one caller. A squeeze play puts maximum pressure on all players still in the hand because they face a re-raise with additional money already in the pot.
Fold vs 3-Bet
Fold vs 3-Bet tracks how often you fold when facing a 3-bet after you made the initial preflop open raise. A very high fold-to-3-bet makes you exploitable because opponents can 3-bet you profitably with any two cards.
Call vs 3-Bet
Call vs 3-Bet tracks how often you flat-call a 3-bet after making the preflop open raise, rather than folding or 4-betting. Calling keeps the pot smaller but can leave you at a positional or range disadvantage.
4-Bet vs 3-Bet
4-Bet vs 3-Bet measures how often you put in a 4-bet when facing a 3-bet after your initial open raise. A 4-bet is the fourth raise in the preflop betting sequence and typically represents a very strong or polarized range.
postflop Stats
C-Bet Flop
C-Bet Flop (Continuation Bet — Flop) measures how often you follow up a preflop raise with a bet on the flop. A continuation bet leverages your perceived range advantage as the preflop aggressor. The denominator counts only hands where you were the last preflop raiser and saw the flop.
C-Bet Turn
C-Bet Turn (Second Barrel) measures how often you continue betting on the turn after already making a continuation bet on the flop. This stat is only counted when you had a flop c-bet opportunity and took it, and then faced a turn decision.
C-Bet River
C-Bet River (Third Barrel) measures how often you fire a third continuation bet on the river after betting both the flop and the turn. Triple-barreling is one of the most aggressive lines in poker and requires a polarized range of strong value hands and bluffs.
Saw Flop
Saw Flop measures the percentage of dealt hands in which you stayed in to see the flop. This includes hands where you posted a blind and checked through as well as hands where you voluntarily called or raised.
WWSF
WWSF (Won When Saw Flop) tracks how often you win the hand — by showdown or by everyone else folding — once you have seen the flop. It reflects your overall postflop effectiveness.
WTSD
WTSD (Went To Showdown) measures how often you go all the way to showdown once you have seen the flop. A high WTSD can indicate a calling-station tendency; a low WTSD suggests frequent folding on later streets.
W$SD
W$SD (Won Money at Showdown) tracks how often you win the pot when the hand goes to showdown. A high W$SD means you are showing down strong hands; a low W$SD means you are frequently reaching showdown with the worst hand.
Aggression Factor
Aggression Factor (AF) is the ratio of aggressive postflop actions (bets and raises) to passive ones (calls). An AF of 1 means you bet/raise as often as you call; higher values indicate a more aggressive postflop style.
