A session of bridge consists of several deals (also called hands or boards). A hand is dealt, the bidding (or auction) proceeds to a conclusion and then the hand is played. Finally, the hand's result is scored.
The aim of a single deal is to achieve the highest score with given cards. The score is affected by two principal factors: the number of tricks bid in the auction, and the number of tricks taken during play.
The concept of contract, which distinguishes contract bridge from its predecessors, refers to a statement by one partnership that they shall take at least a certain number of tricks, with a given suit as trumps, or without trumps.
