Stagger movement

Two rows of tables are set up beside each other so that board sharing is possible. For example, with 8 and 10 tables the arrangement is:

1 2 3 4

5 6 7 8

1 2 3 4 5

6 7 8 9 10

With two sets of boards sharing is not necessary.

The pairs move as in a whist movement, boards up 1 table, E-W up 2 tables (or down 1 and 2 respectively) and because there is sharing, the boards do not need to stay on the one side of the movement. The E-W pairs must be careful when they reach the end of a row as they must swap rows and go to the other end.

When the boards have been played by all tables (i.e., after 1/2 N rounds), they are removed and a new set introduced; at the same time the E-W pairs move up 1 table. The movement then continues as before while the director may score the first half. The advantages of this movement are exactly the same as those in the standard twin Mitchell, with the added advantage that it works for all even numbers of tables.
