Doubles Round-Robin Tournament

[Dart54]

Planning tournament with 20 people.  Partners will change after each match.  Each match or set will be four games.  lAfter all matches are completed (each player having played with each person in the tournament) the player that wins the most games will be declared the winner.  I have scheules for 6 up to 9 players, but I am at a loss how to plan for 20.  We will have the use of 4 courts.  Any help you can provide will be appreciated by this old tennis player (78).

Have you looked at the Whist schedules? These may be most of what you want, only you need to rearrange the tables/matches into rounds of 4 games.  Follow the schedules link above and then press the button called Whist.
