A game of
Texas hold 'em in progress. "Hold 'em" 8️⃣ is a popular form of poker.
Poker is a family of
comparing card games in which players wager over which hand 8️⃣ is best according to that
specific game's rules. It is played worldwide, but in some places the rules may vary.
8️⃣ While the earliest known form of the game was played with just 20 cards, today it is
usually played with 8️⃣ a standard deck, although in countries where short packs are
common, it may be played with 32, 40 or 48 8️⃣ cards.[1] Thus poker games vary in deck
configuration, the number of cards in play, the number dealt face up or 8️⃣ face down, and
the number shared by all players, but all have rules that involve one or more rounds of
8️⃣ betting.
In most modern poker games, the first round of betting begins with one or more
of the players making some 8️⃣ form of a forced bet (the blind or ante). In standard poker,
each player bets according to the rank they 8️⃣ believe their hand is worth as compared to
the other players. The action then proceeds clockwise as each player in 8️⃣ turn must
either match (or "call") the maximum previous bet, or fold, losing the amount bet so
far and all 8️⃣ further involvement in the hand. A player who matches a bet may also
"raise" (increase) the bet. The betting round 8️⃣ ends when all players have either called
the last bet or folded. If all but one player folds on any 8️⃣ round, the remaining player
collects the pot without being required to reveal their hand. If more than one player
remains 8️⃣ in contention after the final betting round, a showdown takes place where the
hands are revealed, and the player with 8️⃣ the winning hand takes the pot.
With the
exception of initial forced bets, money is only placed into the pot voluntarily 8️⃣ by a
player who either believes the bet has a positive expected value or who is trying to
bluff other 8️⃣ players for various strategic reasons. Thus, while the outcome of any
particular hand significantly involves chance, the long-run expectations of 8️⃣ the players
are determined by their actions chosen on the basis of probability, psychology, and
game theory.
Poker has increased in 8️⃣ popularity since the beginning of the 20th century
and has gone from being primarily a recreational activity confined to small 8️⃣ groups of
enthusiasts to a widely popular activity, both for participants and spectators,
including online, with many professional players and 8️⃣ multimillion-dollar tournament
prizes.[2]
History [ edit ]
While poker's exact origin is the subject of debate, many
game scholars point to the 8️⃣ French game Poque and the Persian game As-Nas as possible
early inspirations.[3] For example, in the 1937 edition of Foster's 8️⃣ Complete Hoyle, R.
F. Foster wrote that "the game of poker, as first played in the United States, five
cards 8️⃣ to each player from a twenty-card pack, is undoubtedly the Persian game of
As-Nas." However, in the 1990s the notion 8️⃣ that poker is a direct derivative of As-Nas
began to be challenged by gaming historians including David Parlett. What is 8️⃣ certain,
however, is that poker was popularized in the American South in the early 19th century,
as gambling riverboats in 8️⃣ the Mississippi River and around New Orleans during the 1830s
helped spread the game. One early description of poker was 8️⃣ played on a steamboat in
1829 is recorded by the English actor, Joe Cowell. The game was played with twenty
8️⃣ cards ranking from Ace (high) to Ten (low).[4]
In contrast to this version of poker,
seven-card stud only appeared in the 8️⃣ middle of the 19th century, and was largely spread
by the US military.[5] It became a staple in many casinos 8️⃣ following the second world
war, and grew in popularity with the advent of the World Series of Poker in the
8️⃣ 1970s.[6]
Texas hold 'em and other community card games began to dominate the gambling
scenes over the next couple of decades. 8️⃣ The televising of poker was a particularly
strong influence increasing the popularity of the game during the turn of the
8️⃣ millennium, resulting in the poker boom a few years later between 2003 and 2006. Today
the game has grown to 8️⃣ become an extremely popular pastime worldwide.
Gameplay [ edit

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