Contract bridge, or simply bridge, is a trick-taking card game using a standard 52-card deck. In its basic format, it is played by four players in two competing partnerships, with partners sitting opposite each other around a table. Millions of people play bridge worldwide in clubs, tournaments, online and with friends at home, making it one of the world's most popular card games, particularly among seniors. The World Bridge Federation (WBF) is the governing body for international competitive bridge, with numerous other bodies governing it at the regional level.
A trick-taking game is a card or tile-based game in which play of a hand centers on a series of finite rounds or units of play, called tricks, which are each evaluated to determine a winner or taker of that trick. The object of such games then may be closely tied to the number of tricks taken, as in plain-trick games such as contract bridge, whist, and spades, or to the value of the cards contained in taken tricks, as in point-trick games such as pinochle, the tarot family, briscola, and most evasion games like hearts. Trick-and-draw games are trick-taking games in which the players can fill up their hands after each trick. In most variants, players are free to play any card into a trick in the first phase of the game, but must follow suit as soon as the stock is depleted. Trick-avoidance games like reversis or polignac are those in which the aim is to avoid taking some or all tricks.
500 or Five Hundred is a trick-taking game developed in the United States from Euchre. Euchre was extended to a 10 card game with bidding and a Misère contract similar to Russian Preference, producing a cutthroat three-player game like Preference and a four-player game played in partnerships like Whist which is the most popular modern form, although with special packs it can be played by up to six players.
In the card game contract bridge, the Losing-Trick Count (LTC) is a method of hand evaluation that is generally only considered suitable to be used in situations where a trump suit has been established and when shape and fit are more significant than high card points (HCP) in determining the optimum level of the contract. The method is generally not considered suitable for no trump or misfit hands; also, the trump suit is generally considered to require at least eight cards in length with no partner holding fewer than three.
Skat, historically Scat, is a three-player trick-taking card game of the ace–ten family, devised around 1810 in Altenburg in the Duchy of Saxe-Gotha-Altenburg. It is the national game of Germany and, along with Doppelkopf, it is the most popular card game in Germany and Silesia and one of the most popular in the rest of Poland. A variant of 19th-century Skat was once popular in the US. John McLeod considers it one of the best and most interesting card games for three players, and Kelbet described it as "the king of German card games." The German Skat Association assess that it is played by around 25 million Germans – more than play football.
Polish Club is a bridge bidding system which was developed in Poland, where it is the most popular bidding system, and which is also used by players of other countries. It is a type of small club system.
Sheng ji is a family of point-based, trick-taking card games played in China and in Chinese immigrant communities. They have a dynamic trump, i.e., which cards are trump changes every round. As these games are played over a wide area with no standardization, rules vary widely from region to region.
Tiến lên is a shedding-type card game originating in southern China and Vietnam. It may be considered Vietnam's national card game, and is also played in the United States, sometimes under the names Viet Cong, VC, Thirteen, or Killer.
Zar Points (ZP) is a statistically derived method for evaluating contract bridge hands developed by Zar Petkov. The statistical research Petkov conducted in the areas of hand evaluation and bidding is useful to bridge players, regardless of their bidding or hand evaluation system. The research showed that the Milton Work point count method, even when adjusted for distribution, is not sufficiently accurate in evaluating all hands. As a result, players often make incorrect or sub-optimal bids. Zar Points are designed to take many additional factors into consideration by assigning points to each factor based on statistical weight. While most of these factors are already implicitly taken into account by experienced players, Zar Points provides a quantitative method that allows them to be incorporated into bidding.
The trump coup is a contract bridge coup used when the hand on lead has no trumps remaining, while the next hand in rotation has only trumps, including a high one that would have been onside for a direct finesse if a trump could have been led. The play involves forcing that hand to ruff, only to be overruffed. A similar motive is met in coup en passant, where indirect finesse is used instead of direct.
In the card game contract bridge, DONT is a conventional overcall used to interfere with an opponent's one notrump (1NT) opening bid. DONT, an acronym for Disturb Opponents' Notrump, was designed by Marty Bergen, and is therefore also referred to as "Bergen over Notrump". Although the method is often criticized for being too nebulous, it remains fairly popular. The convention was first published in the September/October 1989 issue of Bridge Today.
Backwash squeeze is a rare squeeze which involves squeezing an opponent which lies behind declarer's menace. A variation of this, known as the "Sydney Squeeze" or "Seres Squeeze", was discovered in play at a rubber bridge game in Sydney, Australia, in 1965, by the Australian great Tim Seres; it was later attested by famous bridge theorist Géza Ottlik in an article in The Bridge World in 1974, as well as in his famous book Adventures in Card Play, co-authored with Hugh Kelsey.
Two-ten-jack is a Japanese trick-taking card game for two players that takes its name from the three highest-scoring cards in the game: the 2, 10 and Jack in three different suits.
Svoyi Koziri, also known as Svoi Kozyri or Vsyak svoi kozyri, is a Russian going-out card game for two players which some consider an elaboration of the Czech game Sedma. This game is one of perfect information and hence entirely of foresight and calculation. It differs from almost all other card games, in that the element of luck is eliminated, as, at any one time in the game, a player will know exactly which cards his opponent has.
Konter a Matt, Kontra a Matt or Konter a Midd is a Luxembourgish trick-taking card game played by four players. The game is popular enough to have been televised on RTL, Luxembourg's leading TV station and for tournaments to be organised. Konter a Matt is one of a family of similar games, known as the Couillon Group, played in the Benelux area. Other games in the family include the Belgian game of Couillon, known as Kwajongen in Flemish areas and Kujong in Luxembourg, the Dutch game of Troeven and the Belgian games of Brûte and Gamelle.
Newmarket is an English card game of the matching type for any number of players. It is a domestic gambling game, involving more chance than skill, and emerged in the 1880s as an improvement of the older game of Pope Joan. It became known in America as Stops or Boodle before developing into Michigan. In 1981, Newmarket was still the sixth most popular card game in Britain.
Maw, formerly also Mawe, was a Scottish card game for two players, popularised by James I, which is ancestral to the Irish national game of Twenty-five as well as the Canadian game of Forty-fives. Maw appears to be the same as Five Cards, a game described by Charles Cotton in the 17th century. The game disappeared from the literature after the period of the English Commonwealth, only to emerge in Ireland in the 19th century in new forms for two or more players and known as Five and Ten, Spoil Five and Forty-Five. These new variants are still played today, the latter has evolved into the Canadian game of Forty-fives.
Within contract bridge a stolen bid is a bid which usually lacks connection to the bidders own hand, and instead is used for blocking a certain bid to be expressed from the next opponent. To "steal a bid" is mainly done when the opponent to the right has given a conventional bid which the opponent to the left is likely to reply to. By far, most stolen bids are related to the Stayman convention. But also other conventions where some kind of reply is expected, the "reply range" can at least in theory be stolen. Blackwood is another example of a convention that might be exposed to a stolen bid.
Bruus, formerly Brausebart or Brusbart, is a north German card game for four players in two teams of two. It was once highly popular but has since died out except for a few pockets in the state of Schleswig-Holstein. As Brusbart, it was the ancestor of a family of similar games in northern Europe, including Swedish Bräus and Danish Brus which are still played today. Bruus features 'daring and tormenting' which has been said to give the game a certain charm. Once considered the national game of Hamburg, Bruus is a descendant of Karnöffel, the oldest identifiable European card game in the history of playing cards with a continuous tradition of play down to the present day. The game is named after the Bruus or Brusbart, once its top card, but now its second-highest trump.
Sjavs is a Danish card game of the Schafkopf family that is played in two main variants. In Denmark, it is a 3-player game, played with a shortened pack of 20 cards; in the Faroe Islands, where it is very popular, it is a four-hand, partnership game using a standard piquet pack of 32 cards.
