With 14 weeks, the schedule can never be balanced in the sense that some players must have more matches than others. But here is a possible solution:
Court 1 Court 2 Byes
(10 4 v 7 12) ( 8 2 v 5 1) ( 3 9 11 6)
( 9 3 v 8 11) ( 7 1 v 6 2) ( 4 10 12 5)
( 3 2 v 7 4) ( 1 9 v 12 5) (10 11 8 6)
( 4 1 v 8 3) ( 2 10 v 11 6) ( 9 12 7 5)
(10 11 v 12 4) ( 5 9 v 3 6) ( 7 1 2 8)
( 9 12 v 11 3) ( 6 10 v 4 5) ( 8 2 1 7)
(11 1 v 3 7) ( 6 4 v 8 9) (12 5 10 2)
(12 2 v 4 8) ( 5 3 v 7 10) (11 6 9 1)
( 8 5 v 11 7) (12 1 v 6 9) ( 4 10 3 2)
( 7 6 v 12 8) (11 2 v 5 10) ( 3 9 4 1)
( 4 11 v 1 6) (10 8 v 9 2) (12 3 7 5)
( 3 12 v 2 5) ( 9 7 v 10 1) (11 4 8 6)
( 1 3 v 12 10) ( 4 9 v 5 7) (11 8 6 2)
( 2 4 v 11 9) ( 3 10 v 6 8) (12 7 5 1)
Players 1,2,5,6,7,8,11 & 12 have 9 games each and 5 bye rounds.
Players 3,4,9 & 10 have 10 games each and 4 bye rounds.
A player's 9 or 10 partners are all different. All 11 opponents are seen at least once and at most twice.
Hope that helps.
