Title: horseshoe schedule
Post by: bobbyboy on April 25, 2012, 09:12:34 AM
hi     I can't find a whist round robin schedule for 30 players. I am running a horseshoe league where each player has a different partner each week.  Had 31   one dropped out.    28 and 32 listed   but no 30   ??

Hi Robert,

There is no listing because it is impossible to have a balanced schedule.  In this situation, I usually try to give everyone the same number of games, so the 30 round schedule below where everyone gets 2 byes (last column) and 28 games would be my recommendation.  All the partnerships in the schedule are different, and no two players oppose more than twice.

Hope that helps.

Ian.
