Poker Glossary: Every Term You Need to Know

Poker has its own language. Whether you are a beginner hearing "pot odds" for the first time or an experienced grinder looking up "equity realization," this glossary has you covered. We have compiled over 80 essential poker terms with clear, practical definitions.

Terms with dedicated articles on GrindLab include deeper links so you can explore further. We regularly update this glossary with new terms — use it as your go-to reference whenever you encounter unfamiliar poker jargon.

A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | R | S | T | U | V | W

A

All-in

Betting all of your remaining chips on a single action. Once you are all-in, you cannot be forced out of the hand — you are eligible to win the main pot up to the amount you have invested from each opponent.

Ante

A forced bet that every player at the table must post before each hand. Antes increase the pot size preflop and create more incentive to play hands. In tournaments, antes typically begin in the middle stages to accelerate action.

Aggression Factor

A statistic that measures how aggressively a player bets and raises relative to how often they call. Calculated as (Bets + Raises) / Calls. A higher aggression factor indicates a more aggressive player. Useful in HUD-based analysis.

B

Backdoor (Draw)

A draw that requires hitting on both the turn and the river to complete. For example, holding two hearts with one heart on the flop means you need hearts on both remaining streets. Backdoor draws add a small amount of equity — typically 1-3% — to your hand.

Bad Beat

Losing a hand despite being a heavy statistical favorite. For example, getting your money in with A♠ A♥ against 7♦ 2♣ and losing when the board runs out 7-7-2-K-7. Bad beats are inevitable and a normal part of variance.

Bankroll

The total amount of money you have set aside specifically for playing poker. Your bankroll is separate from your living expenses. Proper bankroll management is one of the most critical skills for long-term survival in poker.

Bankroll Management

The discipline of choosing stakes and game types that your bankroll can sustain through natural variance. A common guideline for tournaments is 100-200 buy-ins, while cash game players often use 20-50 buy-ins.

Barrel

A bet on a postflop street, usually used in the context of betting multiple streets. A "double barrel" is betting the flop and the turn. A "triple barrel" adds a river bet. Barreling is a key aggression tool for applying pressure.

Big Blind

The larger of the two forced bets posted before each hand. The big blind sits two seats to the left of the dealer button. In cash games, the big blind typically equals the minimum bet for the table.

Blinds

The two forced bets (small blind and big blind) posted before each hand by the players to the left of the dealer button. Blinds ensure there is always money in the pot to fight for.

Blocker

A card in your hand that reduces the probability of your opponent holding a specific combination. If you hold A♠ on a board with three spades, you block the nut flush — your opponent cannot have the A♠ because you have it. Blockers are critical for advanced bluffing decisions.

Bluff

A bet or raise made with a weak hand, intended to make opponents fold stronger hands. Pure bluffs have no chance of winning at showdown and rely entirely on fold equity.

Board

The community cards dealt face-up in the center of the table. In Hold'em, the board consists of up to five cards: three on the flop, one on the turn, and one on the river.

Broadway

Any card ten or higher (T, J, Q, K, A). A "broadway straight" is A-K-Q-J-T, the highest possible straight. Broadway cards are premium holdings preflop because they make top pair and strong straights.

Bubble

The point in a tournament where one more elimination will put the remaining players into the money. Bubble play is heavily influenced by ICM because the pay jump from zero to minimum cash is the largest relative increase in the tournament.

Buy-in

The amount of money required to enter a poker game or tournament. In a $100 tournament, the buy-in is $100 (often split into the prize pool contribution and a fee).

C

Call

Matching the current bet to stay in the hand. Calling is a passive action — it does not put pressure on opponents and does not generate fold equity.

C-bet (Continuation Bet)

A bet made on the flop by the player who raised preflop. The c-bet leverages the initiative and perceived range advantage from raising. Standard c-bet sizes range from 25-75% of the pot depending on board texture and range dynamics.

Check

Declining to bet when no bet has been made in the current round. Checking passes the action to the next player. You can only check if no one has bet before you in that round.

Check-raise

Checking with the intention of raising after an opponent bets. The check-raise is a powerful move that builds the pot with strong hands and can also be used as a bluff to represent strength.

Chip EV ($EV)

A decision's expected value measured purely in chips, ignoring tournament payout implications. In cash games, chip EV equals real-money EV. In tournaments, chip EV and monetary EV diverge due to ICM.

Cold Call

Calling a raise (or re-raise) when you have not yet voluntarily put money in the pot on that street. Cold calling a 3-bet, for example, means calling a re-raise without having been the original raiser.

Combo Draw

A hand with multiple draws simultaneously — for instance, a flush draw combined with a straight draw. Combo draws often have 12-15 outs and can be favorites against made hands on the flop.

Cutoff

The seat directly to the right of the dealer button. The cutoff is the second-best position at the table because it acts second-to-last postflop. Players open wider from the cutoff than from earlier positions.

D

Dealer

The player (or position) designated by the dealer button. The dealer acts last postflop in most variants, giving this position a significant strategic advantage. In casino games, a professional dealer handles the cards while the button rotates.

Deep Stack

Having a large number of chips relative to the blinds — typically 150 big blinds or more. Deep-stacked play increases the importance of implied odds and postflop skill because more money can be won or lost on later streets.

Donk Bet

A bet made out of position by a player who was not the preflop aggressor, typically on the flop. The term originated as a derogatory label, but donk bets have legitimate strategic applications in specific board textures.

Double Barrel

Betting both the flop and the turn. Double barreling is used to apply sustained pressure, represent strong hands, and deny equity to opponents' drawing hands.

Draw

A hand that is not yet complete but has the potential to improve to a strong hand with one or more cards to come. Common draws include flush draws (9 outs), open-ended straight draws (8 outs), and gutshot draws (4 outs).

Dry Board

A board texture with few or no draws available. A flop like K♠ 7♦ 2♣ is dry — there are no flush draws and very few straight draws. Dry boards favor the preflop raiser's range.

E

Early Position

The seats that act first preflop, typically under the gun (UTG) and the next one or two seats. Playing from early position is challenging because many players still act after you. Open tighter from these seats.

Effective Stack

The smaller of the two stacks in a heads-up confrontation. If you have 200 big blinds and your opponent has 80, the effective stack is 80 — that is the maximum either player can win in the hand.

Equity

Your mathematical share of the pot based on your probability of winning at showdown. If you have 60% equity in a $100 pot, your expected share is $60 over the long run. Equity is the foundation of every profitable poker decision. → Read our complete guide: Poker Equity Explained. Calculate it instantly with GrindLab's equity engine.

Equity Realization (EQR)

The percentage of your raw equity that you actually capture in practice. Position, hand playability, and range advantage all affect EQR. A hand with 30% raw equity might only realize 20% if it plays poorly postflop. → Learn more in our equity guide.

Expected Value (EV)

The average profit or loss of a decision over the long run. A play with positive expected value (+EV) makes money on average, even if it loses in any individual instance. EV is calculated by weighting each possible outcome by its probability and payoff.

Exploitation

A strategy that deviates from GTO in order to maximize profit against opponents who make specific mistakes. If a player folds too much, you exploit them by bluffing more. GrindLab's tools are built around exploitation — identifying and capitalizing on real-player tendencies.

F

Final Table

The last table remaining in a multi-table tournament. Reaching the final table typically guarantees a significant pay jump. ICM pressure is at its highest during final table play.

Fish

A weak or recreational player who makes frequent strategic mistakes. The term is not meant as an insult — it simply describes a player whose errors create profitable opportunities for more skilled opponents.

Float

Calling a bet on one street (usually the flop) with a weak hand, intending to take the pot away on a later street — often by betting if the opponent checks. Floating works best in position against opponents who c-bet frequently but give up on the turn.

Flop

The first three community cards dealt face-up simultaneously after the first betting round. The flop dramatically changes hand equities and is where the most critical postflop decisions begin.

Flush

A hand consisting of five cards of the same suit. If more than one player makes a flush, the highest card in the flush wins (the "nut" flush is the ace-high flush).

Flush Draw

Holding four cards of the same suit with one or two cards to come. A flush draw has 9 outs and approximately 36% equity on the flop or 19% on the turn.

Fold

Surrendering your hand and forfeiting any chips already invested in the pot. Folding is often the correct play when your equity is lower than the pot odds being offered.

Fold Equity

The value gained when your opponent folds to your bet or raise. Fold equity allows you to win pots without needing the best hand and is a key reason why aggressive play is more profitable than passive play. → Read more: Fold Equity Explained.

Freeroll

A situation where you can win additional money without risking any of your own, or a tournament with no entry fee. In a hand, a freeroll occurs when two players have the same made hand but one has a draw to a better hand.

G

GTO (Game Theory Optimal)

A strategy based on game theory that cannot be exploited by any opponent. GTO play finds the mathematical equilibrium where no player can improve their results by changing their strategy unilaterally. While theoretically perfect, most real-world profit comes from exploiting deviations from GTO.

Gutshot (Inside Straight Draw)

A straight draw that can only be completed by one specific rank. For example, holding 5-6 on a 3-4-K board — only a 7 completes the straight. Gutshots have 4 outs and roughly 8% equity on the turn or 17% on the flop.

H

Heads-up

A pot or game involving only two players. Heads-up play requires wider ranges and more aggression than full-ring play because you are always in the blinds.

Hero Call

Calling a large bet (usually on the river) with a relatively weak hand — typically a bluff-catcher — because you believe your opponent is bluffing. Hero calls require strong reads and an understanding of opponent tendencies and range composition.

HUD (Heads-Up Display)

A software overlay that displays real-time statistics about your opponents during online play, typically showing stats like VPIP, PFR, and aggression factor. HUDs are allowed on some poker sites and banned on others.

I

ICM (Independent Chip Model)

A mathematical model that converts tournament chip stacks into real-money equity based on the payout structure. ICM accounts for the diminishing value of each additional chip — doubling your stack does not double your prize equity. → Read more: ICM in Poker Explained.

Implied Odds

The expected additional money you can win on future streets if you complete your draw, beyond what is currently in the pot. Deep stacks and hidden draws increase implied odds. Implied odds can justify calls that pure pot odds do not. → Read more: Implied Odds in Poker.

In Position (IP)

Acting after your opponent on each betting round. Being in position gives you more information and more control over the pot. Position is one of the biggest edges in poker.

Isolation Raise

A raise made over one or more limpers with the goal of playing heads-up against a weak player. Isolation raises thin the field and give you position and initiative against a player who has shown weakness.

J

Jam (Shove)

Going all-in, especially as an aggressive move. "Jam" and "shove" are interchangeable. In tournament poker, shoving is a fundamental weapon during the mid and late stages when stack-to-blind ratios are low.

K

Kicker

The side card that breaks ties between hands of the same rank. If two players both have a pair of aces, the player with the higher kicker wins. Kicker strength is a major factor in hand selection — AK dominates AJ because the king outkicks the jack.

L

Late Position

The seats that act last preflop: the cutoff and the button. Late position allows you to see how most opponents act before making your decision, which is a significant strategic advantage. Open wider from late position.

Limp

Calling the big blind preflop instead of raising. Limping is generally considered a weak play in modern strategy because it forfeits initiative and invites multiway pots where your equity realization drops.

Loose

A playing style characterized by entering many pots with a wide range of hands. The opposite of tight. A loose player has a high VPIP (voluntarily put money in pot) percentage.

M

Made Hand

A hand that is already complete and does not need to improve — such as a pair, two pair, trips, a straight, or a flush. Made hands have showdown value but may still be vulnerable to draws.

MDF (Minimum Defense Frequency)

The minimum percentage of your range you must continue with (call or raise) to prevent your opponent from profiting with any two cards as a bluff. MDF = 1 - [Bet / (Pot + Bet)]. Against a pot-sized bet, MDF is 50%.

Middle Position

The seats between early position and late position — typically the hijack and sometimes the lojack. Middle position allows slightly wider opening ranges than early position but is still behind the cutoff and button.

MTT (Multi-Table Tournament)

A tournament format where players start across multiple tables and are consolidated as eliminations occur until a single winner remains. MTTs feature increasing blinds, antes, and dramatic ICM implications as the field narrows.

Multiway Pot

A pot involving three or more players. Multiway pots require tighter ranges and stronger hands to continue because more opponents mean more hands competing for the same pot.

N

Nit

A player who plays extremely tight, entering very few pots and only with premium hands. Nits are predictable and easy to exploit by stealing their blinds frequently and folding when they show aggression.

Nuts

The absolute best possible hand given the current board. On a board of A♠ K♠ Q♠ 7♦ 2♣, the nuts would be J♠ T♠ — the royal flush. The nut hand changes as each community card is dealt.

Nut Advantage

When one player's range contains more of the strongest possible hands (the nuts) than their opponent's range. The player with nut advantage can bet larger and more frequently because they threaten the biggest hands.

O

Offsuit

Two hole cards of different suits, written with an "o" suffix (e.g., AKo). Offsuit hands are weaker than their suited counterparts because they cannot make flushes.

Open Raise

The first voluntary raise preflop. If no one has entered the pot, you "open" by raising. Standard open-raise sizes in modern poker range from 2x to 3x the big blind, depending on position and game type.

Open-Ended Straight Draw (OESD)

A straight draw with eight outs — cards on both ends can complete the straight. Holding 8♣ 7♠ on a 6♦ 9♥ K♣ board, both a 5 and a T complete the straight. OESDs have roughly 32% equity on the flop.

Orbit

One complete rotation of the dealer button around the table, meaning every player has been in every position once. "One orbit" at a 9-player table equals 9 hands.

Outs

The number of remaining cards in the deck that would improve your hand to a likely winner. A flush draw has 9 outs, an OESD has 8 outs, and a gutshot has 4 outs. Use the Rule of 2 and 4 to convert outs into equity percentages.

Overbet

A bet larger than the current pot. Overbets are used with polarized ranges — very strong hands that want maximum value or bluffs that need maximum fold equity. Common overbet sizes are 125-200% of the pot.

Overcards

Hole cards that are higher than any card on the board. Holding A♦ K♠ on a 9♣ 5♥ 3♦ flop, both cards are overcards. Overcards give you approximately 6 outs (three of each rank) to make top pair.

Overpair

A pocket pair higher than any card on the board. Holding Q♠ Q♥ on a 9♣ 7♦ 3♠ flop is an overpair. Overpairs are strong made hands but can be vulnerable to sets, two pair, and straight draws.

P

Pay Jump

The increase in prize money between tournament finishing positions. ICM strategy is heavily influenced by pay jumps — larger pay jumps create more pressure to avoid elimination and more incentive to target short stacks.

PLO (Pot-Limit Omaha)

A poker variant where each player receives four hole cards and must use exactly two of them combined with exactly three community cards. PLO produces more action and closer equity matchups than Hold'em due to the additional hole cards.

Pocket Pair

Two hole cards of the same rank (e.g., 8♠ 8♥). Pocket pairs range from 22 (deuces) to AA (aces). Small pocket pairs are valuable for their set-mining potential — flopping a set occurs roughly 12% of the time.

Polarized Range

A betting range composed of very strong hands (value) and very weak hands (bluffs), with few or no medium-strength hands. Polarized ranges are typically used on the river where there is no more drawing — you either have it or you are bluffing.

Position

Where you sit relative to the dealer button, which determines the order of action. Position is one of the most important concepts in poker — acting later gives you more information and more control. Build and study positional ranges in GrindLab's Range Manager.

Pot

The total amount of chips or money currently at stake in a hand. The pot grows with each bet and call. Your share of the pot is determined by your equity.

Pot Odds

The ratio between the current pot and the cost of calling a bet. Pot odds tell you the minimum equity your hand needs to make calling profitable. If the pot is $100 and you must call $25, your pot odds are 20%. → Read our complete guide: Understanding Pot Odds.

Preflop

The first betting round, before any community cards are dealt. Preflop is where hand selection, position awareness, and range construction begin. Your preflop decisions set the stage for everything that follows.

Probe Bet

A bet made out of position on the turn after the preflop aggressor checked back the flop. Probe bets take advantage of the opponent's capped range (they checked the flop, so they likely do not have a very strong hand).

R

Rainbow

A board where all cards are different suits. A K♠ 9♥ 4♦ flop is rainbow — no flush draw is possible, making the board drier and more favorable for the preflop raiser.

Range

The complete set of hands a player could hold in a given situation. Rather than putting opponents on a single hand, skilled players think in ranges — assigning probabilities to groups of hands based on position, action, and tendencies. Build and organize your ranges with GrindLab's Range Manager.

Range Advantage

When one player's overall range is stronger than their opponent's on a specific board. The player with range advantage can bet more frequently and with more sizing flexibility because their range contains more strong hands.

Rake

The fee taken by the house (casino or online site) from each pot or tournament entry. Rake is how poker rooms make money. Beating the rake requires a meaningful edge over your opponents.

Reg (Regular)

A player who plays poker regularly and seriously, typically with at least a basic understanding of strategy. Regs are harder to exploit than recreational players and often populate mid-to-high stakes games.

Reverse Implied Odds

The potential money you could lose on future streets when you hit your draw but are still behind. Non-nut flush draws carry significant reverse implied odds — you might complete your flush only to find your opponent has a bigger flush. → Read more: Reverse Implied Odds.

Ring Game

Another term for a cash game — a poker game where chips have direct monetary value, players can buy in and leave at any time, and blinds remain constant. The opposite of a tournament.

Risk Premium

An ICM concept describing the extra equity you need beyond chip EV to justify a call in a tournament. Because busting has outsized negative consequences in tournaments, you need better odds than a pure chip-EV calculation suggests. Practice tournament risk premium decisions with GrindLab's RP Trainer.

River

The fifth and final community card. All remaining betting action happens on the river, and then hands are shown down. River decisions are binary — no more cards to come, so you are either ahead or behind.

Run It Twice

An agreement between players to deal the remaining community cards twice after going all-in, splitting the pot based on the results of each run. Running it twice reduces variance but does not change expected value.

S

Semi-bluff

A bet or raise made with a hand that is currently behind but has outs to improve. Unlike a pure bluff, a semi-bluff can win both by making the opponent fold immediately (fold equity) and by hitting the draw if called.

Set

Three of a kind made using a pocket pair plus a matching card on the board. 9♠ 9♥ on a 9♦ K♣ 4♠ board is a set of nines. Sets are extremely strong and well-disguised — they are a primary reason to play pocket pairs.

Short Stack

Having a small number of chips relative to the blinds — typically 20 big blinds or less. Short-stack play in tournaments revolves around push/fold strategy because there is not enough depth for complex postflop play.

Showdown

The point after all betting is complete where remaining players reveal their hands to determine the winner. You only reach showdown if at least two players remain after the final betting round.

SNG (Sit & Go)

A tournament that starts as soon as a set number of players register — typically 6, 9, or 10. SNGs have faster structures than MTTs and emphasize ICM and heads-up play.

Solver

Software that calculates GTO strategies for given poker situations. Solvers find Nash equilibrium solutions by iterating through billions of decision nodes. They are essential study tools but cannot be used during play.

SPR (Stack-to-Pot Ratio)

The ratio of the effective stack to the pot size at the start of postflop play. A low SPR (under 4) favors committing with top pair. A high SPR (over 10) allows for more postflop maneuvering and rewards hand playability.

Squeeze

A preflop re-raise made after one player opens and one or more players call. Squeezing is profitable because the original raiser's range is capped (they did not 4-bet) and the cold callers typically have medium-strength hands that cannot stand a re-raise.

Stack

The total number of chips a player currently has. In tournaments, your stack size relative to the blinds dictates your strategic options. In cash games, you can typically rebuy to maintain a full stack.

Street

A round of dealing and betting. Hold'em has four streets: preflop, flop, turn, and river.

Suited

Two hole cards of the same suit, written with an "s" suffix (e.g., AKs). Suited hands have about 3-4% more equity than their offsuit counterparts because they can make flushes.

Suited Connectors

Two consecutive cards of the same suit (e.g., 7♥ 8♥). Suited connectors are valuable for their ability to make straights, flushes, and combo draws. They perform best in position and in deep-stacked situations where implied odds are high.

T

Table Image

The perception other players have of your playing style based on your recent actions at the table. If you have been folding for an hour, your table image is tight — and opponents are more likely to fold to your bets. Table image can be leveraged for strategic advantage.

Tell

A physical or behavioral cue that reveals information about a player's hand strength. Tells range from betting patterns and timing to physical gestures. Online tells include bet sizing patterns and time-to-act tendencies.

Tight

A playing style characterized by playing few hands and only entering pots with strong holdings. The opposite of loose. A tight player has a low VPIP percentage. Being selectively tight from early position is a fundamental winning approach.

Tilt

An emotional state where frustration, anger, or anxiety causes a player to deviate from their optimal strategy. Tilt is one of the biggest bankroll killers in poker. Common triggers include bad beats, extended losing streaks, or playing above your comfort level. Managing tilt is as important as understanding strategy.

Top Pair

A pair made using one of your hole cards and the highest card on the board. On a K♣ 8♥ 3♦ flop, holding K♠ Q♠ gives you top pair with a queen kicker. Top pair is a common strong-but-vulnerable hand.

Triple Barrel

Betting on all three postflop streets — flop, turn, and river. Triple barreling applies maximum pressure and forces opponents to have very strong hands to continue. It is used for both value and as a bluff.

Turn

The fourth community card, dealt after the flop betting round. The turn is often called "the most important street" because bet sizes grow and the remaining deck shrinks, making equity calculations more precise. On the turn, multiply your outs by 2 for equity estimation.

U

Under the Gun (UTG)

The position directly to the left of the big blind — the first player to act preflop. UTG is the worst position because you act first with the most players remaining behind you. Open with your tightest range from this seat.

Underdog

The player or hand with less than 50% equity in a matchup. The underdog is the statistical favorite to lose but can still win any individual hand. In poker, even significant underdogs hit often enough to matter.

V

Value Bet

A bet made with a strong hand, intended to be called by weaker hands. The goal is to extract maximum chips from opponents who hold second-best hands. Effective value betting requires accurately assessing what your opponent will call with.

Variance

The natural statistical fluctuations in poker results over time. Even the best players experience extended losing streaks due to variance. The higher the sample size, the closer your results converge to your true win rate. Understanding variance prevents tilt and promotes good bankroll management.

Villain

A generic term for your opponent in a hand. In hand analysis discussions, the opponent is typically called the "villain" while you are the "hero."

VPIP (Voluntarily Put Money In Pot)

A statistic showing the percentage of hands where a player voluntarily puts money into the pot preflop (not counting blinds). A VPIP of 25% means the player enters 1 in 4 hands. It is one of the most fundamental player profiling stats in HUD analysis.

W

Wet Board

A board texture with many possible draws and connecting cards. A flop like J♠ T♥ 9♣ is wet — straight draws, flush draws, and combo draws are everywhere. Wet boards favor the caller's range and require different betting strategies than dry boards.
