History of poker

Harry Truman's poker chips

The history of poker is a matter of some debate. The name of the game likely descended from the French poque, which descended from the German pochen ('to knock'), but it is not clear whether the origins of poker itself lie with the games bearing those names. It closely resembles the Persian game of as nas, and may have been taught to French settlers in New Orleans by Persian sailors. It is commonly regarded as sharing ancestry with the Renaissance game of primero and the French brelan. The English game brag (earlier bragg) clearly descended from brelan and incorporated bluffing (though the concept was known in other games by that time). It is quite possible that all of these earlier games influenced the development of poker as it exists now.

English actor Joseph Crowell reported that the game was played in New Orleans in 1829, with a deck of 20 cards, four players betting on which player's hand was the most valuable. Jonathan H. Green's book, An Exposure of the Arts and Miseries of Gambling (G. B. Zieber, Philadelphia, 1843), described the spread of the game from there to the rest of the country by Mississippi riverboats, on which gambling was a common pastime.

Soon after this spread, the full 52-card English deck was used, and the flush was introduced. During the American Civil War, many additions were made, including draw poker, stud poker (the five-card variant), and the straight. Further American developments followed, such as the wild card (around 1875), lowball and split-pot poker (around 1900), and community card poker games (around 1925). Spread of the game to other countries, particularly in Asia, is often attributed to the U.S. military.

The game and jargon of poker have become important parts of American culture and English culture. Such phrases as ace in the hole, ace up one's sleeve, beats me, blue chip, call one's bluff, cash in, high roller, pass the buck, poker face, stack up, up the ante, when the chips are down, wild card, and others are used in everyday conversation even by those unaware of their origins at the poker table.

Modern tournament play became popular in American casinos after the World Series of Poker began in 1970. It was also during that decade that the first serious strategy books appeared, notably The Theory of Poker by David Sklansky (ISBN 1880685000), Super System by Doyle Brunson (ISBN 0931444014), and The Book of Tells by Mike Caro (ISBN 0897461002).

Poker’s popularity has experienced an unprecedented spike in recent years, largely due to the introduction of online poker and the invention of the hole-card camera which finally turned the game into a spectator sport. Viewers can now follow the action and drama of the game, and broadcasts of poker tournaments such as the World Series of Poker and the World Poker Tour have brought in huge audiences for cable and satellite TV distributors.

Poker game play

The game of poker is played in hundreds of variations, but the following overview of game play applies to most of them.

Depending on the game rules, one or more players may be required to place an initial amount of money into the pot before the cards are dealt. These are called forced bets and come in three forms: antes, blinds, and bring-ins.

Like most card games, the dealer shuffles the deck of cards. The deck is then cut, and the appropriate number of cards are dealt face-down to the players. In a casino a "house" dealer handles the cards for each hand, but a button (any small item used as a marker, also called a buck) is rotated among the players to determine the order of dealing and betting in certain games. In a home game, the right to deal the cards typically rotates among the players clockwise, but a button may still be used.

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. During a round of betting, there will always be a current bet amount, which is the total amount of money bet in this round by the player who bet last in this round. To keep better track of this, it is conventional for players to not place their bets directly into the pot (called splashing the pot), but rather place them in front of themselves toward the pot, until the betting round is over. When the round is over, the bets are then gathered into the pot.

After the first betting round is completed (every participating player having called an equal amount), there may be more rounds in which more cards are dealt in various ways, followed by further rounds of betting (into the same central pot). At any time during the first or subsequent betting rounds, if one player makes a bet and all other players fold, the deal ends immediately, the single remaining player is awarded the pot, no cards are shown, no more rounds are dealt, and the next deal begins. This is what makes it possible to bluff.

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.

Computer players for poker

The game of poker (or at least most of the variants) is considered to be computationally intractable. However, methods are being developed to at least approximate perfect strategy from the game theory perspective in the heads-up (two player) game, and increasingly good systems are being created for the multi-player or ring game. Perfect strategy has multiple meanings in this context. From a game-theoretic optimal point of view, a perfect strategy is a minimax one that cannot expect to lose to any other player's strategy; however, optimal strategy can vary in the presence of sub-optimal players who have weaknesses that can be exploited. In this case, a perfect strategy would be one that correctly or closely models those weaknesses and takes advantage of them to make a profit. Some of these systems are based on Bayes theorem, Nash equilibrium, Monte Carlo simulation, and Neural networks. A large amount of the research is being done at the University of Alberta by the GAMES group led by Jonathan Schaeffer who developed Poki and PsOpt.

One major aspect of poker is being a game of imperfect information. Some cards in play are concealed, so the players cannot deduce the exact state the game is in. This fundamentally differs from games like chess where all information about the game's current state is public. A major part of the skill of live poker games, however, is guessing at the strength of a player's hand by identifying tells made by other players, while concealing one's own. As a computer would not make any tells, playing against a computer would fundamentally change the nature of the game far more than chess and similar games.

Although you cannot read a computer opponent, playing against computer opponents can still help you sharpen your skills by learning how to count outs and play the percentages. With the advancing technology of artificial intelligence, computer players can be created to incorporate bluffs and other human-like decisions.

Online poker

Online poker is the game of poker played over the Internet (online). It has been responsible for a dramatic increase in the number of poker players worldwide, and as of December 2003, revenues from online poker were estimated at US$34 million per month.

Traditional (or "brick and mortar", B&M) venues for playing poker, such as casinos and poker rooms, may be intimidating for novice players and are located in geographically disparate locations. Brick and mortar casinos are also reticent to promote poker because it is very difficult for them to profit from the activity. Though the rake, or time charge, of traditional casinos is often very high, the opportunity costs of running a poker room are even higher. Brick and mortar casinos often make much more money by removing poker rooms and adding more slot machines.

Online venues, by contrast, are dramatically cheaper because they have much smaller overhead costs. For example, adding another table does not take up valuable space like it would for a brick and mortar casino. Online poker rooms tend to be viewed as more player-friendly. For example, the software may prompt the player when it is his or her turn to act. Online poker rooms also allow the players to play for very low stakes (as low as 1¢) and often offer poker freerolls (where there is no entry fee), attracting beginners.

Online venues may be more vulnerable to certain types of fraud, especially collusion between players. However, they also have collusion detection abilities that do not exist in brick and mortar casinos. For example, online poker room security employees can look at the "hand history" of the cards previously played by any player on the site, making patterns of behavior easier to detect than in a casino where colluding players can simply fold their hands without anyone ever knowing the strength of their holding. Online poker rooms also check player's IP addresses in order to prevent players at the same household or at known open proxy servers from playing on the same tables.

The major online poker sites offer varying features to entice new players. One common feature is to offer tournaments called satellites by which the winners gain entry to real-life poker tournaments. It was through one such tournament that Chris Moneymaker won his entry to the 2003 World Series of Poker. He went on to win the main event causing shock in the poker world. The 2004 World Series featured triple the number of players over the 2003 turnout. At least four players in the WSOP final table won their entry through an online cardroom. Like Moneymaker, 2004 winner Greg "Fossilman" Raymer also won his entry at the PokerStars online cardroom.

In December 2003 it was reported that online poker revenues stood at around $34m (€ 40m) per month and were growing by 27% per month. By March 2005, at peak times approximately 100,000 people were playing for real money at the various cardrooms with a like number playing free games.

In October 2004, Sportingbet Plc, at the time the world's largest publicly traded online gaming company (SBT.L), announced the acquisition of ParadisePoker.com, one of the online poker industry's first and largest cardrooms. The $340 million dollar acquisition marked the first time an online cardroom was owned by a public company. Since then, several other cardroom parent companies have gone public.

In June 2005, PartyGaming, the parent company of the largest online cardroom, went public on the London Stock Exchange, achieving an initial public offering market value in excess of $8 billion dollars. At the time of the IPO, ninety-two percent of Party Gaming's income came from poker operations.

Famous poker quotations
