This movement was devised by John "Spider" Harris (as supplied by George Coffin) and hence the name "Web". This is useful for a medium to large one-session event where a Mitchell type of tournament is required. An even number of tables is required in the whole field.
This field is, broken down into two groups of tables for the purpose of board moving, and stay as one group for the purpose of moving the pairs.
An odd number of sets of boards is required (for example 7 sets of 3 or 4 boards, 9 sets of 3 boards, 11 sets of 2 boards, 13 sets of 2 boards). The tables are numbered from 1 to 2N and there must be 2 copies of each board in play. The duplication of the boards can be done by the players or they can be pre duplicated.
Tables 1 to N/2 play the first set of boards and tables N/2+1 to 2N play the second set of boards. In the first group of tables the first board set goes on table 1, the second on 2, etc., with the excess sets on a relay table at the end. In the second set of tables the highest numbered set goes on table 2N, set 1 goes on table 2N-l, set 2 goes on table 2N-2, etc., with the excess again on a relay table. For example with 7 sets of boards and 10 tables the following arrangement can be made:
In the first group, the boards move down one table at each change so that tables 1 through 5 play the boards in ascending order.
In the second group the boards move down one table also, but tables 6 through 10 play the boards in descending order.
The E-W pairs always move up 1 table ignoring any sectional boundaries and irrespective of the number of tables (never skip).
All players play all boards in this event but all N-S's do not meet all E-W's. As such, if this is used in qualifying events, the seeding of pairs is necessary for the starting positions so that all seeded pairs N-S meet all seeded pairs E-W.
