You are all set to move for the next round of play. But not yet. Wait for the Director to announce the change. It might go something like this: "O.K., folks, all change for round 2. East/West move to the next higher table, Boards to the next lower table." What does this mean? Exactly what it says. The East/West players will move to the next higher adjacent table. If you are sitting at table number 3 E/W, you move to table number 4 E/W; if at 8 move to 9; and so on. If there are 12 tables and you are at table 12, you move to table 1. If you are sitting E/W you will move to the next higher numbered table at the end of every round of play. Do this when the Director calls a change for the next round. 
         The Duplicate Boards on the other hand move in the opposite direction; they move to the next lower adjacent table. The Boards at table 6 will move to table 5; the ones at table 10 will move to table 9; and so on. If there are 13 tables, the Boards at table 1 will move to table 13. Even though North/South are responsible for the movement of the Boards, the Director will sometimes assist in this process.
         The tables are usually arranged in a circle or in rows and the players will move in a clockwise direction while the Boards move in counterclockwise direction. The Director will usually facilitate the movement of players and boards. 

The Duplicate session should proceed in a stable, orderly fashion. But if there are an even number of tables then a problem arises. At some point in the session players will get cards that they have already played. To avoid this from happening, the Director at some point will call for a skip. 
       " For this round East/West players will skip a table."  So if you are at table 4 go to table 6; if at table 9 go to 11; and so on. If there are 12 tables, the team at table 12 goes to table 2 (skipping table 1); and the team at table 11 goes to table 1 (skipping table 12).
         If there is a skip there is only one skip per session and this must take place at the halfway point (or sooner) of the session.

If the number of teams at a Duplicate game are a multiple of 2, that is, an even number, then every team will have opponents and play every round. But if there is an odd number of teams, let's say there are 15 teams, then one team will have to sit out. That is, during every round there will be a team that will not be playing. There will be a different team sitting out every round and no team will sit out more than once.
          During any given session in which there is a sit out, all the teams sitting out will be from one direction. Either only the North/South teams will take turns sitting out or only the East /West teams. Which direction (North/South or East/West) sits out is at the discretion of the Director.

The way the boards and the teams move, North/South are stationary while East/West move, is known as a Mitchell movement. At the end of the session there are two winners: a North/South winner and  an East/West winner. Also note that North/South teams never play against other North/South teams, and East/West teams never play against other East/West teams.
           There are other types of Duplicate Bridge movements. One such type is the Howell movement: at the end of each round all the North/South teams and all the East/West teams move to a designated position and table. (One or more teams do, however, stay stationary.)  Thus every team will play against every other team and there will be only one winner. A "true" game of Duplicate. Howell movements are usually done with 5 or less tables. 


This board (7) was played three times: North/South pairs 1, 2 and 3 against corresponding East/West pairs 8, 1 and 3. After each time the board is played, the results are put in the appropiate row and column.
The Traveling Score Slip* (see figure 6) is a printed form that "travels" with the Duplicate Board. It is a folded slip of paper (to conceal the results of previous scores) and is usually in the North pocket of the Board. It should only be unfolded after the hand is played. To see the score before playing the hand gives that person an unfair advantage: he will know how to bid and play the hand. This is a big No-No. 
         When a Board is played for the first time North will enter the Board number on both sides of the Traveling Score Slip. 
         It is only after the hand is played, with both teams agreeing on the final result, that the cards are put back into the slots and the result is entered in the Traveling Score Slip.

* Most sectional, regional and national tournaments use 
   Pickup Slips that are collected after the end of each round.
