      THE DUPLICATE BOARDS
      
      A duplicate board containing a pack is provided for each deal to be 
      played during a session. Each board is numbered and has four pockets to 
      hold the four hands, designated North, East, South and West. The dealer 
      and vulnerability are designated as follows: 
       
      
      
        
          | North Dealer | Boards | 1 | 5 | 9 | 13 |

          | Both Sides Vulnerable | Boards | 4 | 7 | 10 | 13 | 
      
      
      The same sequence is repeated for Boards 17-32, and for each subsequent 
      group of 16 boards. 
      No board that fails to conform to these conditions should be used. If 
      such board is used, however, the conditions marked on it apply for that 
      session.

      ARRANGEMENT OF TABLES
      
      Four players play at each table, and tables are numbered in a sequence 
      established by the Director. He designates one direction as North; other 
      compass directions assume the normal relationship to North.

      PARTNERSHIPS
      
      The four players at each table constitute two partnerships or sides, 
      North-South against East-West. In pair or team events, the contestants 
      enter as pairs or teams and retain the same partnerships throughout a 
      session (except in the case of substitutions authorized by the Director). 
      In individual events each player enters separately, and partnerships 
      change during a session.

      ASSIGNMENT OF SEATS
      
      
        - A. Initial Position 
- The Director assigns an initial position to each contestant 
        (individual, pair or team) at the start of a session. Unless otherwise 
        directed, the members of each pair or team may select seats among those 
        assigned to them by mutual agreement. Having once selected a compass 
        direction, a player may change it within a session only upon instruction 
        or with permission of the Director.
          
- B. Change of Direction or Table 
- Players change their initial compass direction or proceed to another 
        table in accordance with the Director's instructions. The Director is 
        responsible for clear announcement of instructions; each player is 
        responsible for moving when and as directed, and for occupying the 
        correct seat after each change.
