Card game
"Poker player" redirects here. For the magazine, see Poker Player
A game of
Texas hold 'em in progress. "Hold 'em" 🍐 is a popular form of poker.
Poker is a family of
comparing card games in which players wager over which hand 🍐 is best according to that
specific game's rules. It is played worldwide, but in some places the rules may vary.
🍐 While the earliest known form of the game was played with just 20 cards, today it is
usually played with 🍐 a standard deck, although in countries where short packs are
common, it may be played with 32, 40 or 48 🍐 cards.[1] Thus poker games vary in deck
configuration, the number of cards in play, the number dealt face up or 🍐 face down, and
the number shared by all players, but all have rules that involve one or more rounds of
🍐 betting.
In most modern poker games, the first round of betting begins with one or more
of the players making some 🍐 form of a forced bet (the blind or ante). In standard poker,
each player bets according to the rank they 🍐 believe their hand is worth as compared to
the other players. The action then proceeds clockwise as each player in 🍐 turn must
either match (or "call") the maximum previous bet, or fold, losing the amount bet so
far and all 🍐 further involvement in the hand. A player who matches a bet may also
"raise" (increase) the bet. The betting round 🍐 ends when all players have either called
the last bet or folded. If all but one player folds on any 🍐 round, the remaining player
collects the pot without being required to reveal their hand. If more than one player
remains 🍐 in contention after the final betting round, a showdown takes place where the
hands are revealed, and the player with 🍐 the winning hand takes the pot.
With the
exception of initial forced bets, money is only placed into the pot voluntarily 🍐 by a
player who either believes the bet has a positive expected value or who is trying to
bluff other 🍐 players for various strategic reasons. Thus, while the outcome of any
particular hand significantly involves chance, the long-run expectations of 🍐 the players
are determined by their actions chosen on the basis of probability, psychology, and
game theory.
Poker has increased in 🍐 popularity since the beginning of the 20th century
and has gone from being primarily a recreational activity confined to small 🍐 groups of
enthusiasts to a widely popular activity, both for participants and spectators,
including online, with many professional players and 🍐 multimillion-dollar tournament
prizes.[2]
History [ edit ]
While poker's exact origin is the subject of debate, many
game scholars point to the 🍐 French game Poque and the Persian game As-Nas as possible
early inspirations.[3] For example, in the 1937 edition of Foster's 🍐 Complete Hoyle, R.
F. Foster wrote that "the game of poker, as first played in the United States, five
cards 🍐 to each player from a twenty-card pack, is undoubtedly the Persian game of
As-Nas." However, in the 1990s the notion 🍐 that poker is a direct derivative of As-Nas
began to be challenged by gaming historians including David Parlett. What is 🍐 certain,
however, is that poker was popularized in the American South in the early 19th century,
as gambling riverboats in 🍐 the Mississippi River and around New Orleans during the 1830s
helped spread the game. One early description of poker was 🍐 played on a steamboat in
1829 is recorded by the English actor, Joe Cowell. The game was played with twenty
🍐 cards ranking from Ace (high) to Ten (low).[4]
In contrast to this version of poker,
seven-card stud only appeared in the 🍐 middle of the 19th century, and was largely spread
by the US military.[5] It became a staple in many casinos 🍐 following the second world
war, and grew in popularity with the advent of the World Series of Poker in the
🍐 1970s.[6]
Texas hold 'em and other community card games began to dominate the gambling
scenes over the next couple of decades. 🍐 The televising of poker was a particularly
strong influence increasing the popularity of the game during the turn of the
🍐 millennium, resulting in the poker boom a few years later between 2003 and 2006. Today
the game has grown to 🍐 become an extremely popular pastime worldwide.
Gameplay [ edit

Further information on betting rules: Betting in poker
In casual play, the right 🍐 to
deal a hand typically rotates among the players and is marked by a token called a
dealer button (or 🍐 buck). In a casino, a house dealer handles the cards for each hand,
but the button (typically a white plastic 🍐 disk) is rotated clockwise among the players
to indicate a nominal dealer to determine the order of betting. The cards 🍐 are dealt
clockwise around the poker table, one at a time.
One or more players are usually
required to make forced 🍐 bets, usually either an ante or a blind bet (sometimes both).
The dealer shuffles the cards, the player on the 🍐 chair to their right cuts, and the
dealer deals the appropriate number of cards to the players one at a 🍐 time, beginning
with the player to their left. Cards may be dealt either face-up or face-down,
depending on the variant 🍐 of poker being played. After the initial deal, the first of
what may be several betting rounds begins. Between rounds, 🍐 the players' hands develop
in some way, often by being dealt additional cards or replacing cards previously dealt.
At the 🍐 end of each round, all bets are gathered into the central pot.
At any time
during a betting round, if one 🍐 player bets, no opponents choose to call (match) the
bet, and all opponents instead fold, the hand ends immediately, the 🍐 bettor is awarded
the pot, no cards are required to be shown, and the next hand begins. This is what
🍐 makes bluffing possible. Bluffing is a primary feature of poker, distinguishing it from
other vying games and from other games 🍐 that use poker hand rankings.
At the end of the
last betting round, if more than one player remains, there is 🍐 a showdown, in which the
players reveal their previously hidden cards and evaluate their hands. The player with
the best 🍐 hand according to the poker variant being played wins the pot. A poker hand
comprises five cards; in variants where 🍐 a player has more than five cards available to
them, only the best five-card combination counts. There are 10 different 🍐 kinds of poker
hands, such as straight flush and four of a kind.
Variants [ edit ]
2006 WSOP Main
Event table
Poker 🍐 has many variations,[7][8] all following a similar pattern of play[9]
and generally using the same hand ranking hierarchy. There are 🍐 four main families of
variants, largely grouped by the protocol of card-dealing and betting:
Straight A
complete hand is dealt to 🍐 each player, and players bet in one round, with raising and
re-raising allowed. This is the oldest poker family; the 🍐 root of the game as now played
was a game known as Primero, which evolved into the game three-card brag, 🍐 a very
popular gentleman's game around the time of the American Revolutionary War and still
enjoyed in the U.K. today. 🍐 Straight hands of five cards are sometimes used as a final
showdown, but poker is almost always played in a 🍐 more complex form to allow for
additional strategy. Stud poker Cards are dealt in a prearranged combination of
face-down and 🍐 face-up rounds, or streets, with a round of betting following each. This
is the next-oldest family; as poker progressed from 🍐 three to five-card hands, they were
often dealt one card at a time, either face-down or face-up, with a betting 🍐 round
between each. The most popular stud variant today, seven-card stud, deals two extra
cards to each player (three face-down, 🍐 four face-up) from which they must make the best
possible 5-card hand.
Draw poker Five-card draw: A complete hand is dealt 🍐 to each
player, face-down. Then each player must place an ante to the pot. They can then see
their cards 🍐 and bet accordingly. After betting, players can discard up to three cards
and take new ones from the top of 🍐 the deck. Then, another round of betting takes place.
Finally, each player must show their cards and the player with 🍐 the best hand
wins.
Community card poker Also known as "flop poker," community card poker is a
variation of stud poker. 🍐 Players are dealt an incomplete hand of face-down cards, and
then a number of face-up community cards are dealt to 🍐 the center of the table, each of
which can be used by one or more of the players to make 🍐 a 5-card hand. Texas hold 'em
and Omaha are two well-known variants of the community card family.
There are several
methods 🍐 for defining the structure of betting during a hand of poker. The three most
common structures are known as "fixed-limit," 🍐 "pot-limit," and "no-limit." In
fixed-limit poker, betting and raising must be done by standardized amounts. For
instance, if the required 🍐 bet is X, an initial bettor may only bet X; if a player
wishes to raise a bet, they may 🍐 only raise by X. In pot-limit poker, a player may bet
or raise any amount up to the size of 🍐 the pot. When calculating the maximum raise
allowed, all previous bets and calls, including the intending raiser's call, are first
🍐 added to the pot. The raiser may then raise the previous bet by the full amount of the
pot. In 🍐 no-limit poker, a player may wager their entire betting stack at any point that
they are allowed to make a 🍐 bet. In all games, if a player does not have enough betting
chips to fully match a bet, they may 🍐 go "all-in," allowing them to show down their hand
for the number of chips they have remaining.
While typical poker games 🍐 award the pot to
the highest hand as per the standard ranking of poker hands, there are variations where
the 🍐 best hand, and thus the hand awarded the pot, is the lowest-ranked hand instead. In
such games the best hand 🍐 contains the lowest cards rather than the highest cards; some
variations may be further complicated by whether or not hands 🍐 such as flushes and
straights are considered in the hand rankings. There are also games where the highest
and lowest 🍐 hands divide the pot between them, known as "high low split" games.
Other
games that use poker hand rankings may likewise 🍐 be referred to as poker. Video poker is
a single-player video game that functions much like a slot machine; most 🍐 video poker
machines play draw poker, where the player bets, a hand is dealt, and the player can
discard and 🍐 replace cards. Payout is dependent on the hand resulting after the draw and
the player's initial bet.
Strip poker is a 🍐 traditional poker variation where players
remove clothing when they lose bets. Since it depends only on the basic mechanic of
🍐 betting in rounds, strip poker can be played with any form of poker; however, it is
usually based on simple 🍐 variants with few betting rounds, like five card draw.
Another
game with the poker name, but with a vastly different mode 🍐 of play, is called
Acey-Deucey or Red Dog poker. This game is more similar to Blackjack in its layout and
🍐 betting; each player bets against the house, and then is dealt two cards. For the
player to win, the third 🍐 card dealt (after an opportunity to raise the bet) must have a
value in-between the first two. Payout is based 🍐 on the odds that this is possible,
based on the difference in values of the first two cards. Other poker-like 🍐 games played
at casinos against the house include three card poker and pai gow poker.
Computer
programs [ edit ]
A variety 🍐 of computer poker players have been developed by
researchers at the University of Alberta, Carnegie Mellon University, and the
University 🍐 of Auckland amongst others.
In a January 2024 article[10] published in
Science, a group of researchers mostly from the University of 🍐 Alberta announced that
they "essentially weakly solved" heads-up limit Texas Hold 'em with their development
of their Cepheus poker bot. 🍐 The authors claimed that Cepheus would lose at most 0.001
big blinds per game on average against its worst-case opponent, 🍐 and the strategy is
thus so "close to optimal" that "it can't be beaten with statistical significance
within a lifetime 🍐 of human poker playing."[11]
