Preflop 32 guides

How a player gets into pots: how many hands they play, how they open and limp, how they defend their blinds, and how they handle 3-bets, 4-bets and 5-bets.

• VPIPVPIPVPIP (voluntarily put money in pot) is the percentage of hands in which a player calls or raises before the flop. The HUD treats 18–38% as typical: below that the player is tight, above it they’re loose.
• Preflop raise (PFR)PFRPFR (preflop raise) measures how often a player raises at least once before the flop, out of the hands where they had a preflop decision. The HUD treats 12–26% as typical. Read it next to VPIP: the two together show what share of a player’s hands they play aggressively.
• Raise first in (RFI)RFIRaise first in (RFI) is how often a player open-raises when everyone before them has folded. The HUD treats 18–45% as typical overall and keeps it by seat, because a good player opens far more on the button than under the gun.
• Open limpOLOpen limp is how often a player limps in, just calling the big blind, in a pot nobody has entered yet. The typical range is 0–12%; above that, the HUD’s read is simple: isolate them.
• LimpLmpLimp is how often a player just calls the big blind in an unraised pot, whether they’re first in or behind other limpers. The HUD treats 0–15% as typical; higher numbers belong to players who want to see cheap flops.
• Iso-raiseIsoIso-raise is how often a player raises over one or more limpers, out of their first decisions in an unraised pot with a limper in front. The HUD treats 15–45% as typical. High means they attack limpers; low means they over-limp or fold behind them.
• Steal attempt (ATS)ATSSteal attempt (ATS) is how often a player open-raises from the cutoff, button or small blind once the action folds to them. Typical is 28–55%; above 55%, the HUD’s read is to re-steal lighter.
• Fold to steal (SB and BB)FtS-SBFtS-BBFold to steal is how often a player in the small blind or big blind folds when the cutoff, button or small blind opens and nobody else is in. A typical small blind folds 55–85% of steals; a typical big blind folds 35–62%.
• BB call vs stealCvSBB call vs steal (CvS) is how often a player in the big blind just calls when the cutoff, button or small blind opens and everyone else folds. Most players flat 25–50% of the steals they face.
• 3-bet vs steal (SB and BB)3bS-SB3bS-BB3-bet vs steal is how often a player in the small blind or big blind re-raises when the cutoff, button or small blind opens and nobody else is in. For both blinds the typical range is 6–16% of the steals they face.
• BB defend vs stealBBDefBB defend vs steal is how often a player in the big blind continues, by calling or 3-betting, when the cutoff, button or small blind opens and everyone else folds. It’s 100% minus BB fold to steal, and the typical range is 38–65%.
• Cold callCCCold call (CC) is how often a player just calls an open raise when they had put no chips in voluntarily, blinds included. The typical range is 4–16%; players above it flat a lot and are good squeeze targets.
• Fold vs openFvOFold vs open (FvO) is how often a player folds when they face a single open raise, nobody has called it yet, and they have no chips in voluntarily. The HUD gives it no typical range; as a rough guide, 70–88% is ordinary.
• SqueezeSqzSqueeze (Sqz) is how often a player 3-bets when someone has opened and at least one player has called. The typical range is 4–12%; above it, flatting an open in front of that player gets expensive.
• Fold to squeezeFSqzFold to squeeze (FSqz) is how often a player who cold-called an open folds when someone behind them 3-bets. The typical range is 55–85%; above it, their flat calls are easy to squeeze out of the pot.
• 3-bet3B3-bet (3B) is how often a player re-raises when they face exactly one raise before the flop and have chips to do it. The HUD’s typical range is 5–12%: under it their 3-bets are strong, over it they re-raise light.
• Fold to 3-betF3BFold to 3-bet (F3B) is how often a player who opened folds when someone re-raises them. The HUD’s typical range is 40–65%: above it, their opens are a target for light 3-bets; below it, they defend and you 3-bet for value.
• Call 3-betC3BCall 3-bet (C3B) is how often a player who opened just calls when someone re-raises them. The HUD’s typical range is 25–50%: above it they flat too many hands, below it they mostly fold or 4-bet.
• 4-bet4B4-bet (4B) is how often a player who opened re-raises again after someone 3-bets them, when they have chips to do it. The HUD’s typical range is 5–15%: under it their 4-bets are premiums only, over it they 4-bet light.
• Cold call 3-betCC3BCold call 3-bet (CC3B) is how often a player with no chips in calls when they face an open and a 3-bet together. The HUD’s typical range is 0–8%; anything above that means they flat re-raises far too often.
• Fold to 3-bet coldFC3BFold to 3-bet cold (FC3B) is how often a player with no chips in folds when they face an open and a 3-bet together. Most players fold the large majority of the time, roughly 86–99%; lower numbers mean they come along or re-raise.
• Cold 4-betC4BCold 4-bet (C4B) is how often a player with no chips in re-raises when they face an open and a 3-bet, if they have chips to do it. The HUD’s typical range is 1–6%; most cold 4-bets are premium hands.
• Fold to 4-betF4BFold to 4-bet (F4B) is how often a player who made a 3-bet folds when someone re-raises to a 4-bet. The HUD’s typical range is 40–70%: above it, their 3-bets fold too easily to a 4-bet bluff; below it, 4-bet them for value only.
• Call 4-betC4Call 4-bet (C4) is how often a player who made a 3-bet just calls when they’re 4-bet. The HUD’s typical range is 15–40%. A high number means they take 4-bets to the flop; a low one means they answer with a fold or a shove.
• 5-bet5B5-bet (5B) is how often a player who made a 3-bet raises again when they face a 4-bet, which at most stack depths means moving all-in. The HUD’s typical range is 5–25%, and in most home games a 5-bet is aces or kings far more often than a bluff.
• Fold to 5-betF5BFold to 5-bet (F5B) is how often a player who made a 4-bet folds when someone re-raises again. The HUD’s typical range is 30–70%. It’s the most direct measure of how many of their 4-bets are bluffs, and one of the slowest stats to fill.
• Limp-foldL-FLimp-fold (L-F) is how often a player who limped folds when the pot is then raised. The HUD’s typical range is 30–70%. A high number makes your iso-raises win the pot on the spot; a low one means you’re raising for value against someone who’ll see the flop.
• Limp-callL-CLimp-call (L-C) is how often a player who limped calls when someone raises behind them. The HUD’s typical range is 25–65%. A high number marks a sticky limper you raise for value and bigger; a low one means they fold or re-raise instead.
• Limp-raiseL-RLimp-raise (L-R) is how often a player who limped re-raises when someone raises behind them: the classic limp-reraise. The HUD’s typical range is 0–10%. Most players almost never do it, and when they do, it’s usually a very big hand.
• Open sizeOSzOpen size (OSz) is a player’s average first raise into an unopened pot, in big blinds. The HUD gives it no typical range: online games often open 2–2.5 bb, PokerNow home games 3–5 bb or more, especially with a straddle.
• 3-bet size3BSz3-bet size (3BSz) is a player’s average 3-bet as a multiple of the open they re-raised: 9 bb over a 3 bb open is 3.0x. The HUD shows no typical range; about 3x in position and 3.5–4x out of position is a common baseline.
• 4-bet size4BSz4-bet size (4BSz) is a player’s average 4-bet as a multiple of the 3-bet they re-raised: 20 bb over a 9 bb 3-bet is 2.2x. The HUD shows no typical range; 2.2–2.5x is a common baseline at 100 bb, and jams push it far higher.

Flop 29 guides

The stats that start on the flop and repeat on every street: c-bets and barrels, donk bets, stabs, check-raises, raises, folding by bet size, and bet sizing. Each guide covers the flop, turn and river versions of its stat.

• Donk betDonkA donk bet is a bet out of position into the player who held the betting lead, made before that player acts. Most players donk 3–15% of the times they get the chance; higher means they lead too often, lower means they nearly always check to the aggressor.
• Fold to donk betFDnkFold to donk bet (FDnk) is how often the previous street’s aggressor folds when a player out of position leads into them. The HUD treats 30–55% as typical; higher means bluff leads make money, lower means lead only for value.
• Raise donk betRDnkRaise donk bet (RDnk) is how often the previous street’s aggressor raises when a player out of position leads into them. The HUD treats 5–20% as typical; above that your leads get attacked, below it a raise is usually a strong hand.

River and showdown 5 guides

How hands end: how often a player gets to showdown, how often they win there, how their river calls do, and how often their river bets are bluffs.

• Went to showdown (WTSD)WTSDWent to showdown (WTSD) is the share of flops a player sees that they take all the way to showdown. The HUD’s typical range is 24–34%: higher means they rarely let a hand go, lower means they fold a lot before the end.
• Won at showdown (W$SD)W$SDWon at showdown (W$SD) is how often a player wins money in the hands where they reach showdown. The HUD’s typical range is 45–58%; a lower number means they bring too many losing hands to the end.
• Won when saw flop (WWSF)WWSFWon when saw flop (WWSF) is the share of flops a player sees that end with them winning money, at showdown or because everyone else folded. The typical range is 40–52%; the stat lives in the player database rather than on the badges.

Overall 4 guides

The numbers behind every other stat: the sample size, the win rate, and how aggressive a player is after the flop.

• HandsHHands is the number of finished hands the HUD has recorded with a player dealt in, shown as “412 h” on their badge. It’s the sample behind everything else, but each stat has its own, smaller sample: the times its spot came up.
• Win rate (BB/100)BB/100Win rate is the net big blinds a player has won per 100 hands, shown as BB/100 (+12, −35). It has no typical range, and over most samples you’ll see, luck outweighs skill: read it as a record of results, not a skill rating.
• Aggression factor (AF)AFAggression factor (AF) is a player’s postflop bets and raises divided by their calls. The HUD treats 1.5–3.5 as typical: under 1.5 they mostly call, over 3.5 they rarely call, and checks and folds don’t count at all.
• Aggression frequency (AFq)AFqAggression frequency (AFq) is the percentage of a player’s postflop actions, checks aside, that are bets or raises. The HUD treats 30–50% as typical across the flop, turn and river together, and 28–52% on each street.
