PROGRESSIVE BRIDGE. This is simply a movement of the players from table to table, much as described under the heading of compass whist. The players may either agree that all the N & S pairs shall sit still, all the E & W pairs moving one table; or they may arrange for the winners to move in a certain direction. In all progressive games, sometimes called Drive Bridge, there are no rubbers or games, as one table would keep all the others waiting. An even number of deals, usually four, is the rule for each round before moving.
DUPLICATE BRIDGE. This is bridge with the hands kept separate and put into trays to be carried from table to table. The methods will be found fully described under the titles for duplicate whist. In order to prevent the players from giving too much attention to the honours in declaring, it is sometimes the rule to add a certain number of points to the trick scores, as a bonus. This is called Bridge to the Score. Four deals is a round, before changing adversaries, and fifty points are added to the score of the side having the greater trick score. Another method is to add fifty points to the side winning a game, if a game is won before moving, and then to add a definite number of points for every trick point that one side may be ahead of the other on unfinished games; or as many points as the higher score below the line.
None of these methods have proved attractive enough to be popular, however, although the first is the one commonly adopted for club tournaments, adding fifty points bonus for the higher trick score, regardless of any games or rubbers. All the additions of percentages require special score cards and the services of some alleged expert to run the game, and even then they are not attractive. The problem of duplicate bridge remains as yet unsolved, so far as a popular game is concerned.
SIX-HAND BRIDGE. This is played by six persons, sitting with two card tables pushed together so as to make one. Each dealer sits at the long end of the table, the two dealers being partners. On each side of one sits a pair of adversaries so that the initial arrangement, if pair A had the deal, would be this:—
Numbers are placed on the tables to indicate the positions to which the players shall move after each deal. The player at 6 goes to 5; 4 to 3; 3 to 2; 2 to 1, and 1 to 6. Each pair of partners, as they fall into the end seats, have the deal.
If the dealer at either end will not declare on his own cards, he passes it, and the Dummy hand opposite him must be handed to the dealer that sits at the other end of the long table, who must declare for his partner. The usual four hands are dealt and played at each table, and scored as usual.
Three scores must be kept, because there are three separate rubbers going on at once,—that between A and B; between A and C, and between B and C. If one pair wins its rubber against one of the others, three players will be idle at one end of the table for one deal, but then all will come into play again, for the next deal. Some persons think this is better than four playing a rubber while two look on.
DOUBLE DUMMY BRIDGE. In this form of the game, the dealer always deals for himself. His adversary sits next him on the left for the first deal, and leads for the first trick before the Dummies are exposed. There is no doubling. On the next deal, the adversary must sort his Dummy’s hand and must lead from it, before looking at his own. If the declaration is passed, Dummy must make it on the lines laid down for passed makes in Bridge for Three, which has already been described. There is no penalty for a revoke made by either Dummy; but otherwise the laws of bridge govern.
