New to poker? Start with how to play.
No term matches that.
The count starts with the big blind as the first bet and the open as the second, so the reraise is the third. A 3-bet range can be built for value only, or mix value hands with bluffs that have blockers or playability.
Also called three-bet, reraise, 3bet.
See also: 4-bet, Open raise, Squeeze, Cold 4-bet
With 100 big blinds stacks, a 4-bet commits a large share of the stack, so 4-bet ranges are narrow and the next raise is often all-in.
Also called four-bet, 4bet.
See also: 3-bet, 5-bet, Cold 4-bet
A player who is all-in cannot be forced out of the hand and can win only up to the amount they put in from each opponent; any extra betting goes to a side pot.
Also called shove, jam, push.
See also: Effective stack, Raise, Side pot
Example: A Q on K 7 2 has a backdoor flush draw. Backdoor draws add only a few percent of equity but help a hand keep playing.
Also called runner-runner, backdoor.
See also: Flush draw, Draw, Equity
Also called roll.
See also: Risk of ruin, Variance, Unit
Having one big blind already in the pot gives the BB a good price to defend, so it calls a wide range against late-position opens. The big blind is also the unit stacks and results are measured in.
Also called big blind, BB.
See also: SB, Big blind (unit), Blinds, Defend
A 200 stack in a 1/2 game is 100bb. Win rates are often given in big blinds per 100 hands, written bb/100.
Also called bb, big blinds, BB/100, bb/100.
See also: BB, Effective stack, Unit
A balanced strategy includes bluffs so that strong hands still get called. A pure bluff has little chance to win at showdown.
See also: Semi-bluff, Value bet, Blocker
Also called community cards.
See also: Board texture, Flop
Texture decides how many draws exist and how much hand strengths can change on later cards. A K 7 2 flop is dry; a J 10 9 flop is wet.
Also called texture.
See also: Dry board, Wet board, Monotone, Paired board
Because it is guaranteed position after the flop, the button opens one of the widest ranges at the table. The button marker moves one seat to the left after each hand.
Also called button, BTN, dealer, on the button.
See also: CO, In position, Position, Steal
The preflop aggressor continues the betting. How often and how large to c-bet depends heavily on board texture and position.
Also called continuation bet, cbet.
See also: Delayed c-bet, Donk bet, Board texture
Unlike tournaments, there is no payout ladder, so chip expected value is the goal. Common table sizes are 6-max and 8 or 9 handed.
Also called ring game.
See also: No Limit Hold'em, Big blind (unit), Rake
See also: Bet, Check-raise
Also called x/r, check raise.
See also: Raise, Check, Out of position
Example: J 10 on 9 8 2 has 15 outs: 9 hearts plus the 6 non-heart queens and sevens. Strong combo draws can be close to even money against a made hand.
See also: Flush draw, Open-ended straight draw, Semi-bluff
A pocket pair has 6 combos, a suited hand 4 and an offsuit hand 12, so AK has 16 in total. Cards on the board or in your hand remove combos from an opponent's range.
Also called combinations, hand combos.
See also: Range, Blocker, Pocket pair
A preflop flat call is often condensed: the best hands would have raised and the worst folded.
Also called condensed range.
See also: Capped range, Polarized, Range
Defense is often measured as a frequency: how often a range continues against a given raise size.
Also called blind defense, defense.
See also: BB, Steal, Minimum defense frequency
The name once implied a weak play, but leads are part of many theoretical strategies on some boards.
Also called donk, lead.
See also: C-bet, Out of position, Probe bet
Also called drawing hand.
See also: Outs, Flush draw, Open-ended straight draw, Semi-bluff
Example: K 7 2 . Rainbow suits and unconnected ranks make it hard for a hand to improve dramatically.
Also called static board.
See also: Wet board, Rainbow, Board texture
In casino games the house usually holds the edge. In poker, edge is your expected win rate against the other players after rake.
Also called advantage, player edge.
See also: House edge, Expected value
If you have 200 big blinds and your opponent has 80, the effective stack is 80 big blinds.
Also called effective stacks, eff.
See also: SPR, Big blind (unit), All-in
Equity is measured against a hand or a range. A K has about 46% equity against Q Q preflop. Equity is not the same as expected value, since betting still to come can change who wins.
Also called pot equity.
See also: Pot odds, Range, Expected value, Equity realization
Hands in position and hands that make strong holdings realize more; out-of-position or dominated hands often realize less because they fold before showdown.
Also called realization, EQR.
See also: Equity, In position, Out of position
EV weighs each outcome by its probability. In poker it compares choices: the higher-EV play is better even if it loses this time. In casino games every bet has negative EV equal to its house edge, and the right play is the one that loses least.
Also called EV.
See also: House edge, Variance, Long run
Also called floating.
See also: In position, Bluff, C-bet
Example: a K 8 3 flop. Most of a hand's strategic character is set here, which is why board texture is described by the flop.
See also: Turn, Board texture, Street
See also: Flush draw, Straight, Hand rankings
Example: A 5 on K 9 2 is the nut flush draw. On the flop it completes by the river about 35% of the time.
Also called FD.
See also: Flush, Combo draw, Outs, Backdoor draw
Also called FE.
See also: Semi-bluff, Bluff, Equity
Also called action frequency.
See also: Mixed strategy, Range
Also called boat, full boat.

A GTO strategy is unexploitable in theory but is not designed to take the most from mistakes. For full Hold'em it can only be approximated, and solver outputs depend on the bet sizes and inputs they are given.
Also called game theory optimal, equilibrium strategy, Nash equilibrium.
See also: Solver, Exploit, Mixed strategy
Example: 10 9 on Q 8 3 , where only a J makes the straight.
Also called inside straight draw, belly buster.
See also: Open-ended straight draw, Straight, Outs
From weakest to strongest: high card, one pair, two pair, three of a kind, straight, flush, full house, four of a kind, straight flush. Suits never break ties in Hold'em.
Also called hand rank, hand order.
See also: Kicker, Straight, Flush, Full house
Also called HU.
See also: Multiway, Isolation raise
Also called hand, starting hand, pocket cards.
See also: Pocket pair, Suited, Offsuit
Implied odds let a draw call when pot odds alone are too short, as long as you expect to get paid when you hit. Reverse implied odds are the opposite: a hand that loses more when it is second best.
Also called IO.
See also: Pot odds, Suited connector, Draw
The player in position sees the opponent's action before choosing, can check behind to see a free card, and controls the final pot size on the river.
Also called IP.
See also: Out of position, Position, BTN
Iso raises are usually larger than a standard open, adding about one big blind per limper.
Also called iso, iso-raise, isolation.
See also: Limp, Heads-up, Open raise
On A 8 4 2 3 , A K beats A 9 : both have a pair of aces, and the king outkicks the nine.
Also called side card.
See also: Top pair, Trips, Hand rankings
Limping first in is uncommon in modern cash-game strategy because it gives up the chance to win the blinds right away. Raising after one or more limpers is an isolation raise.
Also called open limp, limp in.
See also: Open raise, Isolation raise, Call
On an 8-max table the order is UTG, UTG+1, LJ, HJ, CO, BTN, SB, BB; 9-handed, a middle position (MP) comes between UTG+1 and LJ. The lojack is a middle position; at 6-max it does not exist, and the first seat to act is called UTG.
Also called lojack, LJ, low jack.
See also: HJ, UTG+1, Position, Middle position
The long run is far longer than most people expect, often tens or hundreds of thousands of hands or rounds.
See also: Expected value, Sample size, Variance
Players make the best five-card hand from their two hole cards and the board. FlopMAX trains cash games, where chips are worth their face value and players can leave or reload at any time.
Also called NLHE, NL, Texas Hold'em, holdem.
See also: Hole cards, Board, Street, Cash game
On J 10 4 2 the nuts is the ace-high flush. The nut flush draw is a draw to that hand. Holding the nuts on the turn does not guarantee the nuts on the river.
Also called the nuts, nut hand, nut.
See also: Blocker, Flush draw, Showdown
FlopMAX calls this RFI, for raise first in. A spot labeled "BTN RFI vs BB Call" means the button opened, everyone else folded, and the big blind called. Open sizes are usually 2 to 3 big blinds, a little larger from the small blind.
Also called RFI, raise first in, open, opening raise.
The small blind is out of position against every other seat postflop, and the big blind against all but the small blind. Out-of-position players must act with less information, which is one reason preflop ranges from the blinds differ from the button's.
Also called OOP.
See also: In position, SB, BB
Example: Q Q on a 10 7 3 flop.
See also: Pocket pair, Top pair, Set
Example: 8 8 3 . Few hands connect strongly with a paired flop, so most ranges miss it, and trips or a full house usually decides the big pots.
See also: Trips, Full house, Board texture
PFR is always at or below VPIP. A large gap between the two means a player calls a lot preflop.
Also called preflop raise.
See also: VPIP, Open raise
Acting later is an advantage: you see what others do before you decide. Seats are grouped as early (UTG, UTG+1), middle (LJ, HJ), late (CO, BTN) and the blinds (SB, BB).
Also called table position, seat.
See also: In position, Out of position, BTN
Facing a 50 bet into a 100 pot, you call 50 to win a final pot of 200, so you need 25% equity to break even.
See also: Equity, Implied odds, Minimum defense frequency
Also called pre.
See also: Flop, Open raise, Street
Probability and odds describe the same thing differently: a 25% chance is 3 to 1 against.
Also called chance.
See also: True odds, Expected value
Also called probe.
See also: Delayed c-bet, Donk bet, C-bet
Example: A 9 4 .
See also: Two-tone, Monotone, Board texture
In No Limit a raise must add at least as much as the previous bet or raise added, and can be as large as your whole stack.
Also called bump.
See also: Bet, 3-bet, Check-raise, All-in
Rake reduces every player's results and makes small edges smaller, which favors tighter preflop play in high-rake games.
See also: Big blind (unit), Expected value
Thinking in ranges instead of single hands is the core of modern strategy: you decide what to do with each hand as part of how your whole range plays the spot.
Also called hand range.
See also: Combos, Polarized, Linear, Capped range
Small samples are dominated by variance; they say little about whether a strategy is good.
See also: Long run, Standard deviation
The small blind acts second to last preflop and first after the flop, so it is out of position against everyone except the big blind. Many strategies from the SB favor raising or folding over flatting.
Also called small blind, SB.
See also: BB, Blinds, Out of position
A semi-bluff can win two ways: the opponent folds, or the draw completes.
See also: Bluff, Draw, Fold equity
Example: 7 7 on a K 7 2 flop. A set is well hidden because the pair is in your hand; compare trips, which uses a pair on the board.
See also: Trips, Pocket pair, Full house
See also: River, Showdown value, Nuts
A solver needs inputs: starting ranges, stack sizes and the bet sizes allowed. Its output is only as good as those inputs and how far it was run toward convergence.
See also: GTO, Mixed strategy, Frequency
FlopMAX labels spots by the preflop action, such as "BTN RFI vs BB Call": the button opened and the big blind called.
Also called node, situation.
See also: Open raise, Position, Range
With 90 behind and 30 in the pot, the SPR is 3. A low SPR means stacks can go in with fewer bets; a high SPR leaves more room for maneuvering.
Also called stack-to-pot ratio.
See also: Effective stack, Pot commitment, Pot
The squeeze uses the dead money from the callers and the fact that a caller's range is often capped. Squeeze sizes are typically larger than a plain 3-bet to account for the extra players.
Also called squeeze play.
See also: 3-bet, Cold call, Capped range
Over many trials, results land within about two standard deviations of the expectation roughly 95% of the time.
Also called SD, std dev.
See also: Variance, Sample size
Raises from the cutoff, button and small blind are often called steals because so many hands in those ranges profit just from the times everyone folds.
Also called blind steal, steal attempt.
See also: Open raise, BTN, Defend
The ace plays high or low: A-2-3-4-5 is the lowest straight and T-J-Q-K-A the highest.
See also: Flush, Open-ended straight draw, Gutshot, Hand rankings
Each suited hand has 4 combos. Suitedness adds a few percent of equity and the chance to make flushes.
Also called s.
See also: Offsuit, Combos, Suited connector
Suited connectors rarely flop a made hand but make straights and flushes that are hard to see coming.
Also called suited connectors, SC.
See also: Suited, Implied odds, Draw
Example: K 7 on a 7 7 2 flop. Trips are easier for opponents to suspect than a set, and the kicker matters when both players hold the trip card.
Also called three of a kind.
See also: Set, Kicker, Paired board
See also: Top pair, Hand rankings, Set
Also called betting unit.
See also: Bankroll, Bet ramp, Big blind (unit)
UTG acts first before the flop and is out of position against most of the table after it, so opening ranges from this seat are the tightest. At a 6-max table UTG is followed by HJ, CO, BTN, SB and BB; at 8-max, UTG+1 and LJ sit between UTG and HJ.
Also called under the gun, UTG.
See also: UTG+1, Position, Open raise
A thin value bet is one that only just gets called by enough worse hands to be worth it.
Also called bet for value.
See also: Bluff, Merged, Showdown value
High variance means big swings in both directions. Correct decisions can still produce losing sessions.
Also called swings.
See also: Standard deviation, Expected value, Risk of ruin
Example: 9 8 6 . Connected ranks and two or more cards of one suit give many straight and flush draws.
Also called dynamic board, coordinated board.
