How to schedule 12 players and 2 courts is described here.  It is possible to do this by rearrangement of the standard whist schedule for 3 courts.  I will reply about 16 players separately.

Is it possible to do a schedule with say 12 or 16 players with only 2 or 3 courts respectively?  I am new to all this and having  trouble understanding how to make it possible.  It is for a group that will play over multiple weeks with members having bye weeks of course.  Thanks in advance.  If this has been answered please let me know where to look.

Ian,

Thank you very much for getting back to me.

The "Spouse Avoiding" schedule is hilariously named and could be very helpful.

Unfortunately, no such schedule exists. You can have a schedule where the one player who you don't play against is not a partner.  This is the spouse avoiding schedule for 8 players.

Ian,

I searched the site but couldn't find:

eight players
doubles tennis
three rounds
only play against a player once
the one player you don't play against, you have as a partner once during the 3 rounds

Is there a solution that meets these requirements?

Any help is much appreciated.

Welcome back!  I think the schedule below should work, each of the 10 rows is a round.

    G1      G2      G2      G2      G3      G3      G3      G4     G4      G4 
  (13  9) (15 18) (19  3) ( 4 11) (16  6) ( 5 17) (14  1) ( 2  7 (20  8) (10 12)
  (14 10) (11 19) (20  4) ( 5 12) (17  7) ( 1 18) (15  2) ( 3  8 (16  9) ( 6 13)
  (15  6) (12 20) (16  5) ( 1 13) (18  8) ( 2 19) (11  3) ( 4  9 (17 10) ( 7 14)
  (11  7) (13 16) (17  1) ( 2 14) (19  9) ( 3 20) (12  4) ( 5 10 (18  6) ( 8 15)
  (12  8) (14 17) (18  2) ( 3 15) (20 10) ( 4 16) (13  5) ( 1  6 (19  7) ( 9 11)
  (20  1) ( 4  6) (13 10) ( 8 17) ( 5 11) ( 9 15) ( 7 18) (19 14 ( 2 12) (16  3)
  (16  2) ( 5  7) (14  6) ( 9 18) ( 1 12) (10 11) ( 8 19) (20 15 ( 3 13) (17  4)
  (17  3) ( 1  8) (15  7) (10 19) ( 2 13) ( 6 12) ( 9 20) (16 11 ( 4 14) (18  5)
  (18  4) ( 2  9) (11  8) ( 6 20) ( 3 14) ( 7 13) (10 16) (17 12 ( 5 15) (19  1)
  (19  5) ( 3 10) (12  9) ( 7 16) ( 4 15) ( 8 14) ( 6 17) (18 13 ( 1 11) (20  2)

Or perhaps you can divide the 20 teams into 2 groups of 10 teams?  Then it is possible to schedule all games to be between group. Let me know and I can find another schedule.
