I need a schedule for 12 players, 8 players will play on 2 courts with 4 players having a bye each round.

Each player will play with a different player each round against 2 different players.

I have time for the number of games that it will take to accomplish this set of rules.

Example 1,2 vs 3,4  on Court 1.    5,6 vs 7,8 on Court 2.  Byes are 9, 10, 11, 12

If the 12 players are the letters A to L, then you could play the following:

[(B J):(F I)] [(---):(---)]
[(G J):(H K)] [(E I):(C L)]
[(E J):(D F)] [(G H):(I L)]
[(A I):(B G)] [(C K):(E H)]
[(A K):(F L)] [(B H):(D J)]
[(A G):(E F)] [(D L):(C I)]
[(B F):(K L)] [(A J):(C E)]
[(A D):(I J)] [(B C):(G K)]
[(E K):(G I)] [(C H):(A F)]
[(C F):(H I)] [(J L):(E G)]
[(B D):(C G)] [(H J):(I K)]
[(H L):(A B)] [(D I):(F K)]
[(B L):(C J)] [(A H):(D G)]
[(B E):(F H)] [(D K):(A L)]
[(C D):(F G)] [(B I):(A E)]
[(G L):(F J)] [(B K):(D E)]
[(J K):(A C)] [(D H):(E L)]

Note that 33 games are necessary if every player is to partner every other player once, so the odd number of games leads to the short first round.
