Neuberg Formula
In duplicate bridge pairs tournaments, the Neuberg formula is a method of adjusting match point scores achieved on boards which have been played fewer times than other boards. Originally developed by Gérard Neuberg of France, its objective is to achieve a formula for the final score of every pair to which each hand they have played contributes with equal weight. Although the objective behind the formula is of questionable soundness, the formula itself follows from well-defined mathematical assumptions, and is almost universally applied in computer-scored bridge tournaments. A board might have been played fewer times than others because: * the movement Movement may refer to: Common uses * Movement (clockwork), the internal mechanism of a timepiece * Motion, commonly referred to as movement Arts, entertainment, and media Literature * "Movement" (short story), a short story by Nancy Fu ... was not completed, or * there was a phantom pair, or * one or more plays of that ...

Duplicate Bridge
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. In duplicate bridge, players normally play all the hands with the same partner, and compete either as a partnership (in a 'Pairs tournament') or on a team with one or more other partnerships ('Te ...

Glossary Of Contract Bridge Terms
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.
