THE LAWS OF DUPLICATE AUCTION.
ОглавлениеDuplicate Auction is governed by the Laws of Auction, except in so far as they are modified by the following special laws:
A. Scoring. In Duplicate Auction there are neither games nor rubbers. Each deal is scored just as in Auction, with the addition that whenever a pair makes 30 or more for tricks as the score of one deal, it adds as a premium 125 points in its honour column.
B. Irregularities in the Hands. If a player have either more or less than his correct number of cards, the course to be pursued is determined by the time of the discovery of the irregularity.
(1) When the irregularity is discovered before or during the original play: There must be a new deal.
(2) When the irregularity is discovered at the time the cards are taken up for overplay and before such overplay has begun: It must be sent back to the table from which it came, and the error be there rectified.
(3) When the irregularity is not discovered until after the overplay has begun: In two-table duplicate there must be a new deal; but in a game in which the same deals are played at more than two tables, the hands must be rectified as is provided above and then passed to the next table without overplay at the table at which the error was discovered; in which case, if a player have less than thirteen cards and his adversary the corresponding surplus, each pair takes the average score for that deal; if, however, his partner have the corresponding surplus, his pair is given the lowest score and his opponents the highest score made at any table for that deal.
C. Playing the cards. Each player, when it is his turn to play, must place his card, face upward, before him and toward the centre of the table. He must allow it to remain upon the table in this position until all have played to the trick, when he must turn it over and place it face downward, nearer to himself; if he or his partner have won the trick, the card should point toward his partner and himself; otherwise it should point toward the adversaries.
The declarer may either play dummy’s cards or may call them by name whenever it is dummy’s turn to play and have dummy play them for him.
A trick is turned and quitted when all four players have turned and ceased to touch their respective cards.
The cards must be left in the order in which they were played until the scores of the deal have been recorded.
D. The Revoke. A revoke may be claimed at any time before the last trick of the deal in which it occurs has been turned and quitted and the scores of that deal agreed upon and recorded, but not thereafter.
E. Error in Score. A proved error in the trick or honour score may be corrected at any time before the final score of the contestants for the deal or deals played before changing opponents has been made up and agreed upon.
F. A New Deal. A new deal is not allowed for any reason, except as provided in Laws of Auction 36 and 37. If there be an impossible declaration some other penalty must be selected.[24] A declaration (other than passing) out of turn must stand;[25] as a penalty, the adversaries score 50 honour points in their honour column and the partner of the offending player cannot thereafter participate in the bidding of that deal.
The penalty for the offence mentioned in Law 81 is 50 points in the adverse honour score.
G. Team Matches. A match consists of any agreed number of deals, each of which is played once at each table.
The contesting teams must be of equal size, but each may consist of any agreed number of pairs (not less than two). One half of each team, or as near thereto as possible, sits north and south; the other half east and west.
In case the teams are composed of an odd number of pairs, each team, in making up its total score, adds, as though won by it, the average score of all pairs seated in the positions opposite to its odd pair.
In making up averages, fractions are disregarded and the nearest whole numbers taken, unless it be necessary to take the fraction into account to avoid a tie, in which case the match is won “by the fraction of a point.” The team making the higher score wins the match.
H. Pair Contests. The score of a pair is compared only with other pairs who have played the same hands. A pair obtains a plus score for the contest when its net total is more than the average; a minus score for the contest when its net total is less than the average.
Note.—Some players in America are adopting the English rule, which allows the dealer to pass, without making any declaration. The usual expression is, “No bid.” Each player to the left may then pass in turn, and if no bid is made the deal passes to the left. The lowest declaration is one club, as spades have a constant value of nine and are always “royals.”
The English rule is to score 50 for little slam and 100 for grand slam, and some American players have adopted that rule.
