Question
QUESTION: I need a party bridge rotation for 32 people, 12 months of the year.   We meet at 2 venues per month, 2 tables per venue.
Thank you!

ANSWER: Hi,

Are the players individuals, pairs or teams of four? Also it seems that only 16 players can play per month. How many months do you want each player to play?

---------- FOLLOW-UP ----------

QUESTION: The players are couples , therefore the rotation should be for 16.   However, once at the designated venue, they play individually using party bridge tallies.    It's the scheduling rotation that I need to ensure each couple plays different couples each month.   Ideally, everyone plays each month at a rotating venue,, two tables per venue.

Appreciate your patience!

Answer
Hi,

I can give you a rotation for 16 pairs where each pair plays every other pair exactly once. The full rotation lasts 15 months but you don't need to use the whole thing if it doesn't suit your purposes.

Give every pair a number from 1-16.

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.
