For Directors
Web Movements

Web movements are variants of Mitchell movements that can have any number of boards in play.

In most tournament and club sessions, each pair plays 24 to 28 boards. Mitchell movements are often used in sections with anywhere from 4 to 17 tables. Mitchells are simple and flexible, but for some table counts each pair misses six to 15 boards, so 20% or more of the comparisons are “apples and oranges.”

Web movements decouple the number of boards from the number of tables. Today’s dealing machines and electronic scorepads enable well-prepared directors to use Webs routinely.

ACBLscore’s Web repertoire is limited. In 2009 I wrote a Mathematica program that can generate ACBLscore external movement files for any Mitchell, Web, or combination Mitchell/Web, including variants with rovers and party tables. The current version (2019 January 29) includes 1,235 pregenerated movements.
