1 Round-robin movements for 3 7 teams David Babcock The Bidding Box Pinecrest, Florida February 7, 2013 This note documents six movements, one per page, following this page, in the order described below (each is underlined). ACBL-legal movements These movements have been prepared with two objectives in mind: Everyone is to play the same boards, or as near to that as possible; All matches are to be scored immediately or after a delay of one round at most. All the movements can be set up in ACBLscore with no difficulty. 3 teams: two 12-board matches, American Whist movement; one set of 36 boards required; everyone plays 24 of the 36 boards 4 teams: three 8-board head-to-head matches, round-robin; two sets of 24 boards required 1 ; everyone plays all the boards 5 teams: four 6-board matches, American Whist movement; one set of 30 boards required; everyone plays 24 of the 30 boards 2 6 teams: five 5-board head-to-head matches, round-robin; three sets of 25 boards required; everyone plays all the boards 7 teams: six 4-board matches, American Whist movement; one set of 28 boards required; everyone plays 24 of the 28 boards 2 A much better, though not-quite-legal, movement for 3 teams 1 can be managed with one set if necessary 2 this movement was published by Pete Matthews of the MIT/Draper Lab Bridge Club
