Question
We have a bridge marathon group that plays 8 times a year with 16 couples. Is it possible you give a rotation where each couple plays with every other couple at least once a year?

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.
