At this stage it might be impossible. I would start writing the players and their schedules on index cards and seeing if you can fit them into the following pattern. 16 is on the left end and does not move--everyone else moves clockwise to face the player/team on the other side.
8 15 7 14 6 13 5
16 1
9 2 10 3 11 4 12If you can find some kind of near fit you might have to provide for makeup games or having extra rounds since it is going to be impossible for all matchups to be made each round. You will have to make the pairings by hand.
If you would like to see the above in a pairing table, click
here and choose "Porter" and "Board Number". Good Luck!
