Tracker statistics: how each one is calculated

VPIP, 3-bet, c-bet, WTSD, BB/100: for every statistic in the tracker, what counts as an action, what counts as an opportunity, and the edge cases.

The tracker's Statistics page shows around fifty frequencies, grouped into categories. This page walks through those categories one by one and gives, for each row, the exact definition the calculation uses. Two trackers can show two different "3-bet" numbers for the same hands: the difference is always in the denominator.

How to read a number

Every statistic has the same shape:

Frequency = actions ÷ opportunities × 100, rounded to one decimal.

An opportunity is a hand where you were in a position to take the action. An action is an opportunity where you took it. Hover a cell in the tracker: the tooltip gives both raw counts, for example 412 / 1830.

The columns

Column	What it reads
TOTAL	Every opportunity of the row
IP / OOP	The same, split by whether you were in or out of position
UTG … BB	Preflop only: the row split by seat
FLOP / TURN / RIVER	Postflop only: the row's version on each street
BB/100	The row's impact on your winrate

The vocabulary of the definitions

Action opportunity: you had at least one decision to make on the street. When a hand goes all-in the board still runs out, but nobody can bet any more: it is not an opportunity for any action statistic (c-bet, donk, probe, check-raise…).
Street reached: the card was dealt and you had not folded before it. This is the base of the showdown statistics only (WTSD, WWSF), where an all-in hand counts normally.
Unopened pot: nobody has bet on the street when the action reaches you. You could therefore bet.
Facing a bet: a bet forces you to answer, whether it is already in when you act or comes after your check. Check then fold is a fold facing a bet.
Street checked through: you checked and nobody bet behind you.
Preflop aggressor: the last preflop raiser. The whole c-bet family is read against them. For donk, probe and stab, the "aggressor" of a street is the last player to bet or raise on the previous street.
In position (IP): last to act among the players still in the hand on that street.
First decision: a few preflop statistics look at the situation at your first voluntary action (RFI, limp, iso, cold call, open-shove).
Pot type: limped (no preflop raise), SRP (one raise), 3-bet pot (two raises or more: 4-bet pots and beyond are folded into it).

The BB/100 column

Read it as an impact on your winrate, not as the winrate of the hands where you took the action:

sum of your net winnings over the hands where you took the action ÷ your total hands played × 100

The winrate of the subset alone would be selection-biased (the hands where you 4-bet win hundreds of BB/100, which teaches nothing). Divided by total volume, the figure says what the action earns or costs your overall winrate, and rows become comparable. A +3 on the 3-Bet row does not mean "my 3-bets win 3 BB/100" but "the hands where I 3-bet add 3 BB/100 to my winrate". The column is green when positive, red when negative, and absent for an opponent: their net result is unknown to us.

Sample size and colours

A cell resting on fewer than 200 opportunities is dimmed. That is a display threshold, not a reliability threshold: above it the figure is not "validated", only less fragile. A few hundred hands are enough to read a VPIP or a PFR; a 3-bet or a c-bet takes a few thousand hands; a river statistic or a Fold to 4-Bet, tens of thousands.

Frequencies are not colour-coded, on purpose: a high Fold to c-bet is exploitable the same way a high VPIP is. What matters is the deviation from a reference, not the value. The tracker leaves the judgement to you.

What is never mixed

Every figure is computed within one format (cash, tournament, spin) and one table environment: heads-up, 3-max, 4 to 6 players, 7 players and more. The environment comes from the number of players actually dealt into the hand, not the nominal table size. The "All" view sums the environments, only when you ask for it.

Preflop

Profile

VPIP

Voluntarily Put money In Pot

Action: You call, bet or raise at least once preflop
Opportunities: Every hand you are dealt

Posting a blind or an ante is not voluntary. A walk in the big blind counts as an opportunity, not as an action. A limp counts.

PFR

Preflop Raise

Action: You raise at least once preflop
Opportunities: Every hand you are dealt

Open, iso, 3-bet, 4-bet or shove: any raise counts. PFR is therefore always lower than or equal to VPIP.

Opening & steal

RFI (open)

Raise First In

Action: Your first action is a raise
Opportunities: Nobody has entered the pot before your first decision: no limp, no raise

Only the first raise of the hand is an open. Limping and then re-raising an iso is a limp-raise, not an RFI.

Steal

Action: Your first action is a raise
Opportunities: Same spot as RFI, but only from the cutoff, the button and the small blind

The small blind counts as a steal seat.

3-Bet & squeeze

3-Bet

Action: You make the second preflop raise
Opportunities: You act with exactly one raise in, and you are not the raiser

Whether you folded, called or raised, the opportunity counts. Facing a 3-bet or a 4-bet is not a 3-bet opportunity: exactly one raise has to be in.

3-Bet vs steal

Action: You 3-bet
Opportunities: You are in the SB or BB, the CO, button or SB opened with no limper before them, and the action reaches you with no call or raise in between

The resteal. Read it alongside the Blind defense category, which shares the same denominator.

Squeeze

Action: You 3-bet
Opportunities: You act with one raise in and at least one player who has already called it

The denominator is the squeeze spot itself: an open, at least one player who called it, and the action on you. This is the classic trackers' definition, so the numbers compare.

Fold to 3-Bet

Action: You fold to the 3-bet
Opportunities: You opened, and the action comes back to you facing a 3-bet

The denominator only keeps the opens that actually faced a 3-bet, with the action back on you. If a third player 4-bets before you, you are answering a 4-bet: the hand does not enter here. Neither does a cold 4-bet, made without having opened.

4-Bet

Action: You make the third preflop raise
Opportunities: You opened, and the action comes back to you facing a 3-bet

Category shown in cash only. In tournaments and spins it gives way to Short stacks.

Fold to 4-Bet

Action: You fold to the 4-bet
Opportunities: You 3-bet, and the action comes back to you facing a 4-bet

A slow sample to build: think tens of thousands of hands.

Blind defense

Fold vs steal

Action: You fold preflop
Opportunities: You are in the SB or BB, the CO, button or SB opened with no limper before them, and the action reaches you with no call or raise in between

A UTG or MP open is not a steal: it does not enter here. If the small blind calls or 3-bets before you, you are no longer defending against a bare steal: the hand leaves the category.

Call vs steal

Action: You call preflop
Opportunities: You are in the SB or BB, the CO, button or SB opened with no limper before them, and the action reaches you with no call or raise in between

Fold vs steal, Call vs steal and 3-Bet vs steal describe the same spot: between the three of them they cover your answers to a steal.

Limp & cold-call

Limp

Action: Your first action is a call, whatever happens next
Opportunities: Nobody has entered the pot before your first decision: no limp, no raise

Completing the small blind is a limp, and a limp-raise is still a limp. An over-limp, behind another limper, does not enter here: the opportunity is reserved for the first player in.

Cold call

Action: Your first action is a call
Opportunities: Exactly one raise is in at your first decision, and you are not in the blinds

A cold call is made with no money already in: defending a blind is not one. The SB and BB columns of this row are therefore empty, and defending against a steal has its own category.

Iso vs limp

Action: You raise
Opportunities: At least one limper and no raise before your first decision

Limp-raise

Action: You raise after limping
Opportunities: All your first-in limps

The denominator includes limps that were never raised. The figure reads as a share of your limps, not as a reaction to an iso.

Short stacks

Open-shove

Action: Your first action is an all-in raise
Opportunities: Nobody has entered the pot before your first decision: no limp, no raise

Category shown in tournaments and spins. The denominator is the same as RFI: the figure reads as the share of your opening opportunities played as a shove. Opening to a normal size and then calling a jam is not an open-shove.

Call vs shove

Action: You call the all-in
Opportunities: An opponent moves all-in preflop and the action reaches you, whether or not it is your first decision

Opening and then facing a jam counts just like facing one straight away: what is read is your answer to the first all-in of the hand.

Limp-fold

Action: You fold
Opportunities: Your first-in limps that actually faced a raise

Unlike Limp-raise, a limp nobody raised does not count: there was nothing to fold to.

Postflop

Postflop rows never name a street: the FLOP, TURN or RIVER column says where the action happens. A row that only exists on one street leaves the other columns empty. Outside tournaments, a filter separates raised pots from limped pots.

One rule holds for the whole section: an opportunity means you could act. A hand that went all-in, or a pot already opened when it was your turn to bet, is never a missed opportunity.

Initiative

C-Bet

Rows “SRP” and “3-Bet pot”

Action: You bet the flop
Opportunities: Preflop aggressor, you have a decision on the flop and nobody has bet before you

Turn column · 2nd barrel

Action: You bet the turn
Opportunities: You c-bet the flop as the preflop aggressor, and nobody has bet before you on the turn

River column · 3rd barrel

Action: You bet the river
Opportunities: Preflop aggressor, you bet flop and turn, and nobody has bet before you on the river

If you are donked into, you no longer have the option to c-bet: the hand is read by Fold vs probe / donk. Turn and River follow the strict definition, chained barrels: an aggressor who checks the flop and then bets the turn makes a delayed c-bet, not a turn c-bet. Both rows read the same stat, one in single-raised pots, the other in 3-bet pots and beyond.

Delayed c-bet

Action: You bet the turn
Opportunities: Preflop aggressor, the flop checked through, and nobody has bet before you on the turn

Checking the flop is not enough: a flop check-call or check-raise is not a c-bet being delayed. And if the opponent bets the turn before you, there is nothing left to delay.

Double delayed c-bet

Action: You bet the river
Opportunities: Preflop aggressor, the flop and the turn both checked through, and nobody has bet before you on the river

Donk

Action: You bet into the aggressor on the flop
Opportunities: You are not the aggressor, nobody has bet, and the aggressor has not acted yet

Betting before the aggressor has acted, whatever your seat. If they have already checked, your bet is a stab.

Probe

Action: You bet the turn
Opportunities: The flop checked through; on the turn you are not the aggressor, nobody has bet, and the aggressor has not acted yet

The aggressor skipped their c-bet, you take the lead on the turn. Calling a c-bet and then betting the turn is not a probe: it is a turn donk, and it does not enter here.

Stab (missed c-bet)

Action: You bet the flop
Opportunities: You are not the aggressor, nobody has bet, and the aggressor checked before you

River column

Action: You bet the river
Opportunities: You are not the aggressor, nobody has bet the river, and the aggressor gave up: the turn checked through, or they have just checked the river

The Turn column shows Probe. On the flop, the opportunity only exists once the aggressor has checked: if you act before them, it is a donk opportunity. A limped pot has no aggressor: any bet into an unopened flop is a stab, and the out-of-position turn lead after a checked flop is a probe.

Bet (unopened pot)

Action: You bet the river
Opportunities: You have a decision on the river and nobody has bet before you

Every role included: whether you are the aggressor or not.

Overbet

Action: Your river bet exceeds 130% of the pot
Opportunities: The rivers where you bet

A share of your river bets, not of your rivers. The size is measured against the pot before the bet. A raise is not counted: it is sized against a pot that already holds the opponent's bet, which is not the same quantity.

Reaction

Fold to c-bet

Rows “SRP” and “3-Bet pot”

Action: You fold to the c-bet
Opportunities: The preflop aggressor bets the flop first and the action reaches you, before or after your check, with no raise in between

Turn column

Action: You fold to the 2nd barrel
Opportunities: The preflop aggressor c-bet the flop, bets the turn first again, and the action reaches you with no raise in between

River column · facing the 3rd barrel

Action: You fold to the 3rd barrel
Opportunities: The preflop aggressor bet flop and turn, bets the river first again, and the action reaches you with no raise in between

Check then fold out of position counts: it is the most common case. Only the preflop aggressor's bet is a c-bet: facing another player's donk or stab, the hand does not enter here. If a player raises the c-bet before the action reaches you, you are answering a raise, and the hand does not enter either. The three columns follow the same chain as the C-Bet row: c-bet, 2nd barrel, 3rd barrel.

Check-raise

Action: You check then raise the flop
Opportunities: You checked the flop, then a bet came

A flop where nobody bets after your check is not an opportunity. The denominator is the classic trackers' one: call, fold or raise after a check.

Float

Action: You bet the turn
Opportunities: In position, you called a flop bet, and the opponent checks the turn

If the opponent bets the turn again, there is no float opportunity: the hand is read by Fold after call.

Fold after call

Action: You fold the turn
Opportunities: You called the flop without ever betting or raising, reached the turn, and faced a turn bet

The row a double-barrelling opponent is aiming at. Check then fold on the turn is counted.

Fold vs stab

Action: You fold the flop
Opportunities: Preflop aggressor, you checked the flop then faced a bet

What happens once you have given up the c-bet. Holds for every pot type and for any bet faced after your check.

Raise vs stab

Action: You raise the flop (check-raise included)
Opportunities: Preflop aggressor, you checked the flop then faced a bet

Fold vs probe / donk

Action: You fold the flop
Opportunities: Preflop aggressor, a bet is already in at your first decision on the flop

Turn column · facing the probe

Action: You fold the turn
Opportunities: Preflop aggressor, you checked the flop, and a bet is already in at your first decision on the turn

Two distinct statistics shown on one row: the donk in the Flop column, the probe in the Turn column. The TOTAL, IP and OOP columns read the donk alone.

Showdown & tendencies

WWSF

Won When Saw Flop

Action: You collect a share of the pot
Opportunities: Every hand where you reach the flop

A split pot counts as won: the test is collecting a share of the pot, not ending with a positive net result.

WTSD

Went To Showdown

Action: Your cards are shown at showdown
Opportunities: Every hand where you reach the flop

A called preflop all-in counts: the board is run out, so the flop is reached.

W$SD

Won money at Showdown

Action: You collect a share of the pot, chops included
Opportunities: Every hand where you go to showdown

Same test as WWSF: a chop counts as won. The row exists for your opponents too, since the hand history says who collected the pot.

Aggression (freq.)

Action: You bet or raise at least once on the street
Opportunities: Every postflop street where you did something other than check: bet, raise, call or fold

An aggression frequency, not the Aggression Factor. It is counted per street, not per action: a street where you bet then raise counts once. A street checked through is not an opportunity. The row has no BB/100, which would be meaningless here.

The winnings figures

They appear above the curves and in session tracking, not in the tables.

Figure	Calculation
Net	Pot collected minus everything you put into the hand, blinds and antes included
Winrate (BB/100)	Net in BB ÷ hands played × 100
All-in EV (BB/100)	Same calculation, with all-in results replaced by their expectation
Showdown / Non-showdown	Net split by whether the hand went to showdown
Net / h, Hands / h	Cash only, always in euros
Rake	Shown as an amount, never coloured as a loss

In tournaments and spins, BB/100 measures the change of your stack in big blinds. Blinds go up and a chip has no fixed monetary value: that figure does not compare with a cash winrate.

All-in EV

EV = equity × (total pot − rake) − your amount invested

Equity is computed at the moment the money goes in, using both players' cards. It is exact with one or two cards to come. For a preflop all-in it is a Monte Carlo estimate over 15,000 run-outs. Ties count as half.

The calculation only covers heads-up all-ins, both players' cards known, with at least one card to come. In every other case (multiway pots, side pots, cards not shown) the hand's EV equals its actual result. The EV curve is therefore a hybrid: adjusted on those all-ins, identical to the winnings curve everywhere else. It is not an estimate of the EV of all your hands.

Aggression Factor

The Players page shows an AF on top of the aggression frequency: (bets + raises) ÷ calls, postflop, counted per action. A player who bets, gets raised and re-raises weighs two aggressive actions on that street. It is not a percentage and it is unbounded: 2.0 means two aggressive actions for every call. This is the classic trackers' definition, so the numbers compare.

An opponent's statistics

The same tables exist for every opponent, with the same definitions and the same splits, W$SD included. Three differences:

no BB/100 column, since their net result is unknown;
in the replayer's stats window, the "SRP" and "3-Bet pot" rows are merged and the pot type becomes a filter;
their cells do not open the underlying hands: their cards are only known to us at showdown.

Below 500 hands observed on a player, a warning reminds you that their frequencies have not converged. It is a general marker: as with your own numbers, what counts is each row's number of opportunities. To put them to work in an analysis, see the villain's range.

Frequently asked questions

My statistics changed without me playing a hand. Why?

Several definitions were tightened in September 2026 so that an opportunity only counts when the action was actually possible. Fold to c-bet now counts check then fold out of position, Check-raise only divides by checks that were followed by a bet, Probe and Delayed c-bet require a flop that checked through, Squeeze only divides by real squeeze spots, and a hand that went all-in is no longer a missed opportunity. Your hands did not change: they are read more accurately, and in a way that compares with other trackers.

Why does a row's BB/100 not look like a winrate?

It is not the winrate of the hands where you took the action. It is the sum of your winnings over those hands, divided by your total hands played, times one hundred. It measures what that action weighs in your overall winrate: it is an impact, which makes rows comparable with each other.

How many hands before a statistic is reliable?

The 200-opportunity threshold under which the tracker dims a cell is a display threshold, not a guarantee. Count opportunities, not hands: a few hundred hands already give a readable VPIP and PFR, a 3-bet or a c-bet takes a few thousand, and a Fold to 4-Bet or a river statistic takes tens of thousands.

Are cash and tournament statistics mixed together?

No. Every figure is computed within one format (cash, tournament, spin) and one table environment (heads-up, 3-max, 4 to 6 players, 7 players and more). A heads-up VPIP and a full-ring VPIP are never added together unless you explicitly pick the All view.
