(11) The rubber continues until two games have been won by the same player; it may consist of two, three, or four games.
(12) When the declarer fulfils his contract, he scores as in Auction. When he fails to do so, both of his adversaries score as in Auction.
(13) Honours are scored by each player separately, i.e., each player who holds one honour scores the value of a trick; each player who holds two honours scores twice the value of a trick; a player who holds three honours scores three times the value of a trick; a player who holds four honours scores eight times the value of a trick; and a player who holds five honours scores ten times the value of a trick. In a no-trump declaration, each ace counts ten, and four held by one player count 100. The declarer counts separately both his own honours and those held by the dummy.
(14) A player scores 125 points for winning a game, a further 125 points for winning a second game, and 250 points for winning a rubber.
(15) At the end of the rubber, all scores of each player are added and his total obtained. Each one wins from or loses to each other the difference between their respective totals. A player may win from both the others, lose to one and win from the other, or lose to both.
[23] This hand is generally dealt opposite to the dealer.
THE LAWS OF DUPLICATE AUCTION.
Duplicate 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.
