Contract bridge in the context of Team game

Zero-sum game is a mathematical representation in game theory and economic theory of a situation that involves two competing entities, where the result is an advantage for one side and an equivalent loss for the other. In other words, player one's gain is equivalent to player two's loss, with the result that the net improvement in benefit of the game is zero.

If the total gains of the participants are added up, and the total losses are subtracted, they will sum to zero. Thus, cutting a cake, where taking a more significant piece reduces the amount of cake available for others as much as it increases the amount available for that taker, is a zero-sum game if all participants value each unit of cake equally. Other examples of zero-sum games in daily life include games like poker, chess, sport and bridge where one person gains and another person loses, which results in a zero-net benefit for every player. In the markets and financial instruments, futures contracts and options are zero-sum games as well.

The International University Sports Federation (FISU; French: Fédération internationale du sport universitaire) is responsible for the organization and governance of worldwide sports competitions for student-athletes between the ages of 17 and 25. It was founded in 1949 as the world governing body of national university sports organizations and currently has 165 member associations (National University Sport Federations) from five continents. Between 1949 and 2011, it was based in Brussels (Belgium); it was relocated to Lausanne (Switzerland) since 2011.

The FISU stages its events every two years. They currently include three World University Games (beach, summer and winter) and 34 World University Championships. It also organizes conferences, forums and seminars to promote sport as a component of the educational system. FISU sanctions other competitions open to university students, such as the biennial World University Bridge Championships in contract bridge, "played under the auspices of the FISU".

Marc Hodler ((1918-10-26)26 October 1918 – (2006-10-18)18 October 2006) was a Swiss lawyer, President of the International Ski Federation (1951–1998), member of the International Olympic Committee (IOC) from 1963 until his death, and bridge player. Hodler is best known for having exposed the Olympic bid scandal for the 2002 Salt Lake City Winter games in December 1998.

Born in Bern, Hodler was a keen skier and first urban member of his national squad. An injury prevented him from entering any international competitions but he became a coach.

Iain Norman Macleod (11 November 1913 – 20 July 1970) was a British Conservative Party politician.

A playboy and professional bridge player in his twenties, after war service Macleod worked for the Conservative Research Department before entering Parliament in 1950. He was noted as a formidable Parliamentary debater and—later—as a platform orator. He was quickly appointed Minister of Health, later serving as Minister of Labour. He served an important term as Secretary of State for the Colonies under Harold Macmillan in the early 1960s, overseeing the independence of many African countries from British rule but earning the enmity of Conservative right-wingers, and the soubriquet that he was "too clever by half".

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 (or, in some settings, books), 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.

Duplicate bridge is a variation of contract bridge where the same set of bridge deals (i.e., the distribution of the 52 cards among the four hands) are played by different competitors, and scoring is based on relative performance. In this way, every hand, whether strong or weak, is played in competition with others playing identical cards, and the element of skill is heightened while that of chance is reduced. This stands in contrast to Bridge played without duplication, where each hand is freshly dealt and where scores may be more affected by chance in the short run.

Four-way card holders known as bridge boards are used to enable each player's hand to be preserved from table to table, and final scores are calculated by comparing each pair's result with others who played the same hand.

The World Bridge Federation (WBF) is the international governing body of contract bridge. The WBF is responsible for world championship competitions, most of which are conducted at a few multi-event meets on a four-year cycle. The most prestigious championships are those for national teams in Open, Women, and Seniors categories: the Bermuda Bowl, Venice Cup, and Senior Bowl (jointly the biennial "World Teams Championships"), and the quadrennial World Team Olympiads, incorporated in the World Mind Sports Games beginning 2008.

The World Bridge Federation was founded August 1958 by delegates from Europe, North America, and South America (now Zones 1 to 3). It is incorporated under the laws of Switzerland as a 'non-profit' organization. Harold Stirling Vanderbilt was made the first honorary member of the WBF for his work developing the game. The current president is Jan Kamras of Sweden.

These terms are used in contract bridge, using duplicate or rubber scoring. Some of them are also used in whist, bid whist, the obsolete game auction bridge, and other trick-taking games. This glossary supplements the Glossary of card game terms.

French-suited playing cards or French-suited cards are cards that use the French suits of trèfles (clovers or clubs ♣), carreaux (tiles or diamonds ♦), cœurs (hearts ♥), and piques (pikes or spades ♠). Each suit contains three or four face/court cards. In a standard 52-card deck these are the valet (knave or jack), the dame (lady or queen), and the roi (king). In addition, in Tarot packs, there is a cavalier (knight) ranking between the queen and the jack. Aside from these aspects, decks can include a wide variety of regional and national patterns, which often have different deck sizes. In comparison to Spanish, Italian, German, and Swiss playing cards, French cards are the most widespread due to the geopolitical, commercial, and cultural influence of France, the United Kingdom, and the United States in the 19th and 20th centuries. Other reasons for their popularity were the simplicity of the suit insignia, which simplifies mass production, and the popularity of whist and contract bridge. The Anglo-Saxon pattern of French-suited cards is so widespread that it is also known as the International or Anglo-American pattern.
