Duplicate bridge is the most widely used variation of contract bridge, used in club and tournament settings. It is called duplicate because the same bridge hand (i.e. arrangement of cards) is duplicated at most of the tables playing, in order to allow a fair comparison of playing skill and reduce "luck of the cards". In this way, every hand, whether good or bad, is played in competition with others playing the identical cards, and the element of competition is heightened whilst that of chance is reduced.
