If a player and his partner make thirteen tricks, independently of any tricks gained by the revoke penalty, they score Grand Slam and add forty points to their honour count.
Little Slam is twelve tricks similarly scored, and adds twenty points to the honour count.
Chicane (one hand void of trumps) is equal in value to three honours, i.e., if partner of player having Chicane scores honours he adds the value of three honours to his honour score, while, if the adversaries score honours, it deducts an equal value from their honour score. Double Chicane (a player and his partner both void of trumps) is equal in value to four honours, and the value thereof may be deducted from the total honour score of the adversaries.
The value of honours, Slam, Little Slam, or Chicane, is in no wise affected by doubling or re-doubling.
At the conclusion of a rubber the scores for tricks, honours, Chicane, and Slam, obtained by each side, are added, and one hundred points are added to the score of the winners of the rubber. The difference between the completed scores is the number of points won or lost by the winners of the rubber.
