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 |
| East Dealer | Boards 2 6 10 14 |
| South Dealer | Boards 3 7 11 15 |
| West Dealer | Boards 4 8 12 16 |
| Neither Side Vulnerable | Boards 1 8 11 14 |
| North-South Vulnerable | Boards 2 5 12 15 |
| East-West Vulnerable | Boards 3 6 9 16 |
| 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.
