LAW 2 - 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
East Dealer:Boards 2 6 10 14
South Dealer:Boards3 7 11 15
West Dealer:Boards4 8 12 16
 
Neither Side Vulnerable:Boards 181114
North-South Vulnerable:Boards 251215
East-West Vulnerable:Boards36916
Both Sides Vulnerable:Boards471013

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.
