Poker terminology glossary
Quick definitions for the terms that show up in real strategy work.
Use this reference when a lesson mentions position, ranges, blockers, SPR, equity, leverage, pot-limit sizing, or exploit language. The definitions are written for No Limit Hold'em and Pot Limit study, with emphasis on how each term affects decisions at the table.
Game flow
Core table language
These terms describe the structure of a hand, from blinds and hole cards through showdown.
Blinds
Forced bets posted by the small blind and big blind before cards are dealt. They create the initial pot and drive pre-flop action.
Button
The dealer position marker. The button acts last after the flop, making it the most profitable position in most games.
Hole Cards
The two private cards dealt to each Hold'em player. They combine with the board to make the best five-card hand.
Pre-flop
The betting round before community cards appear. Decisions are driven by hand class, position, stack depth, and opponent tendencies.
Flop
The first three community cards. The flop defines board texture, range advantage, draw density, and many continuation-bet decisions.
Turn
The fourth community card. Turn cards often change equity, complete draws, and create leverage for larger bets.
River
The fifth and final community card. River decisions are pure value, bluff, bluff-catch, or check-down choices because no future card remains.
Showdown
The point where remaining players reveal hands. The best five-card poker hand wins unless the pot was already awarded by folds.
Side Pot
A separate pot created when one player is all in but others continue betting. Only players who contributed to a side pot can win it.
Actions
Betting and pressure terms
Check
Pass the action without betting when no bet is facing you. Checking keeps the pot unchanged and can protect weaker ranges.
Call
Match the current bet. A call continues with a hand or draw without increasing the price for opponents behind.
Raise
Increase the current bet. Raises build value, deny equity, isolate opponents, or apply pressure to capped ranges.
Fold
Release the hand and give up claim to the pot. Folding is correct when price, equity, or future playability is not good enough.
All In
Put every remaining chip into the pot. All-in decisions depend heavily on stack depth, fold equity, and showdown equity.
Continuation Bet
A bet made by the previous street's aggressor. Usually shortened to c-bet, it represents continued pressure after raising pre-flop or on a prior street.
Donk Bet
A bet into the previous street's aggressor. It is often used when the board strongly favors the caller's range.
Check-Raise
Check first, then raise after an opponent bets. It applies strong pressure and can represent nutted value or selected bluffs.
Probe Bet
A bet by the out-of-position player after the pre-flop aggressor checks back the flop. It attacks missed c-bets and delayed weakness.
Positions
Where action starts and who has information
Under the Gun
The first player to act pre-flop in a full-ring or six-max hand. UTG ranges are usually tight because many players remain behind.
Hijack
A middle-late position two seats right of the button in six-max naming. It can open wider than early position but still faces cutoff, button, and blinds.
Cutoff
The seat directly right of the button. The cutoff can pressure blinds and button but must respect button 3-bets.
Small Blind
The forced-bet seat left of the button. It acts early post-flop and must play carefully because it is out of position.
Big Blind
The forced-bet seat left of the small blind. It receives a discount to call pre-flop but often plays out of position after the flop.
In Position
Acting after your opponent on post-flop streets. Position lets you see checks and bets before choosing your action.
Ranges and blockers
The language of hand groups
Range
The full set of hands a player can realistically hold after taking a line. Good strategy compares ranges instead of guessing one exact hand.
Polarized Range
A range made mostly of strong value hands and bluffs, with fewer medium-strength hands. Large bets are often polarized.
Linear Range
A range built from strongest hands downward without many gaps. Linear 3-bets target callers who continue too wide.
Capped Range
A range unlikely to contain the strongest possible hands because of an earlier action, such as calling instead of 4-betting.
Condensed Range
A range heavy in medium-strength hands, often created by calling. Condensed ranges bluff-catch well but may struggle against big polar bets.
Blocker
A card in your hand that reduces the combinations of strong hands your opponent can hold. Ace blockers are common in pre-flop 4-bet bluffs.
Unblocker
A card that does not remove your opponent's likely folds. Good bluffs often avoid blocking missed draws or weak hands you want them to fold.
Combo
A specific card combination within a hand class. For example, pocket aces has six combinations before blockers are considered.
Nut Advantage
An edge in the strongest possible hands on a board. The player with more nut hands can often apply larger-bet pressure.
Math and stack planning
Terms that explain price and commitment
Equity
Your share of the pot if all remaining cards were dealt and no one folded. Equity changes with board texture and opponent range.
Fold Equity
The value gained when a bet makes opponents fold. Semi-bluffs combine fold equity with the chance to improve when called.
Pot Odds
The price offered by the pot compared with the call amount. A call needs enough equity, implied odds, or future playability to justify the price.
Implied Odds
Future money you expect to win when a draw completes. Implied odds are better with deep stacks and opponents who pay off too often.
Reverse Implied Odds
The risk of making a second-best hand and losing more chips later. Weak top pairs and dominated draws often suffer from this problem.
SPR
Stack-to-pot ratio: effective remaining stack divided by the pot. Low SPR favors commitment with strong one-pair hands; high SPR rewards nutted hands.
Effective Stack
The smaller remaining stack between players in a hand. It determines the maximum amount that can be won or lost between those players.
Expected Value
The long-run value of a decision. A play can lose this time but still be positive EV if it wins enough over repeated situations.
Minimum Defense Frequency
The portion of a range that must continue to avoid being automatically exploited by a bluff at a given bet size.
Post-flop concepts
Board texture and street planning
Dry Board
A board with few draws and limited connectivity, such as K-7-2 rainbow. Dry boards often support small c-bets from the range leader.
Wet Board
A connected or suited board with many draws, such as J-T-9 with two of a suit. Wet boards require careful sizing and protection.
Backdoor Draw
A draw that needs help on both turn and river, such as holding one heart on a two-heart-needed flush path. Backdoors can support flop bluffs.
Overcard
A card higher than the board or a pair. Overcards can add equity or become scare cards for future barrels.
Thin Value
A value bet targeting a narrow set of worse hands that can still call. Thin value requires a clear read on calling ranges.
Bluff Catcher
A hand that beats bluffs but loses to most value bets. River bluff-catching depends on blockers, price, and opponent bluff frequency.
Barrel
Betting on a later street after betting earlier. Good barrels improve your story, add equity, or pressure a range that cannot defend enough.
Leverage
Pressure created by the threat of future bets or stack commitment. Turn bets often create leverage because they imply a possible river shove.
Protection
Betting to deny free cards to hands with equity. Protection is strongest when worse hands can call and many turn cards are bad for your hand.
Opponent profiles
Common player descriptions
Tight
A player who enters relatively few pots. Tight opponents often have stronger ranges when they voluntarily put money in.
Loose
A player who enters many pots. Loose opponents can be exploited with value-heavy betting and disciplined bluff selection.
Aggressive
A player who bets and raises frequently. Aggression can be strong, but over-aggression creates bluff-catching and trap opportunities.
Passive
A player who checks and calls more than they bet or raise. Passive lines often under-bluff rivers and pay off too many value bets.
Station
A player who calls too often and folds too little. Value bet wider against stations and reduce low-equity bluffs.
Nit
An extremely tight player. Nits can be pressured in low-commitment spots but deserve respect when they raise large.
Pot Limit terms
Concepts that matter when the pot caps the raise
Pot-Limit Raise
The largest legal raise in Pot Limit is based on the current pot after calling the existing bet. This creates fast pot growth without unlimited overbets.
Pot-Sized Bet
A bet equal to the current pot. It gives opponents 2:1 immediate pot odds and creates strong future-street commitment pressure.
Redraw
Additional equity that can improve an already made hand or drawing hand. Redraws are crucial in Pot Limit because big pots often involve close equity.
Wrap
A straight draw with many outs, most often discussed in Pot Limit Omaha. In mixed Pot Limit study, wrap awareness helps evaluate draw-heavy boards.
Nut Draw
A draw to the best possible hand, such as the ace-high flush draw. Nut draws tolerate pressure better than dominated draws.
Commitment Threshold
The point where stack and pot size make folding later unattractive or mathematically poor. Pot Limit hands reach this point quickly after pot-sized raises.
How to use the glossary
Pair terms with decisions
The fastest way to learn poker language is to attach every word to a choice: call or fold, small bet or overbet, value or bluff, pressure or pot control. When a lesson uses a term, ask what action changes because that term is true.
- Range term: identify which hands remain after each action.
- Math term: calculate price, equity, and stack depth before clicking.
- Opponent term: change the default only when the profile is reliable.
- Pot Limit term: plan the next legal pot-sized raise before investing.
