Chapter I

Definitions

Adjusted Score   An arbitrary score awarded by the Director (see Law 12). It is either "artificial" or "assigned".
1) An artificial adjusted score is one awarded in lieu of a result because no result can be obtained or estimated for a particular deal (e.g., when an irregularity prevents play of a deal).
2) An assigned adjusted score is awarded to one side, or to both sides, to be the result of the deal in place of the result actually obtained after an irregularity.
Alert   A notification, whose form may be specified by a sponsoring organisation, to the effect that opponents may be in need of an explanation.
Auction 1) The process of determining the contract by means of successive calls.
  2) The aggregate of calls made (see Law 17E).
Bid   An undertaking to win at least a specified number of odd tricks in a specified denomination.
Board 1) A duplicate board as described in Law 2.
  2) The four hands as originally dealt and placed in a duplicate board for play during that session.
Call   Any bid, double, redouble or pass.
Contestant   In an individual event, a player; in a pair event, two players playing as partners throughout the event; in a team event, four or more players playing as team-mates.
Contract   The undertaking by declarer's side to win, at the denomination named, the number of odd tricks specified in the final bid, whether undoubled, doubled or redoubled.
Convention 1) A call that, by partnership agreement, conveys a meaning other than willingness to play in the denomination named (or in the last denomination named), or high-card strength or length (three cards or more) there. However, an agreement as to overall strength does not make a call a convention.
  2) Defender's play that serves to convey a meaning by agreement rather than inference.
Deal 1) The distribution of the pack to form the hands of the four players.
  2) The cards so distributed considered as a unit, including the auction and play thereof.

  2) Declarer's partner's cards, once they are spread on the table after the opening lead.
Event   A contest of one or more sessions.
Follow Suit   Play a card of the suit that has been led.
Game   100 or more trick points scored on one deal.

Partner   The player with whom one plays as a side against the other two players.
Partscore   90 or fewer trick points scored on one deal.
Pass   A call specifying that a player does not, at that turn, elect to bid, double or redouble.
Play 1) The contribution of a card from one's hand to a trick, including the first card, which is the lead.
  2) The aggregate of plays made.
