Question
every couple need to play every other couple  how long will it take and what would the rotation be?

Answer
Hi,

For 12 pairs, each pair has eleven potential opponents so a complete rotation would last eleven sessions. Give each pair a number from 1-12. A complete rotation follows.

Session     Pair Matchups

 1    12-1  11-2  10-3  9-4  8-5  7-6
 2    12-2   1-3  11-4 10-5  9-6  8-7
 3    12-3   2-4   1-5 11-6 10-7  9-8
 4    12-4   3-5   2-6  1-7 11-8 10-9
 5    12-5   4-6   3-7  2-8  1-9 11-10
 6    12-6   5-7   4-8  3-9 2-10 1-11
 7    12-7   6-8   5-9 4-10 3-11  2-1
 8    12-8   7-9  6-10 5-11  4-1  3-2
 9    12-9  8-10  7-11  6-1  5-2  4-3
10    12-10 9-11   8-1  7-2  6-3  5-4

I can answer questions on bidding and on cardplay with the caveat that the former may necessarily involve some subjectivity. I have been playing tournament bridge for over 20 years and I have won several regional tournaments.
