Question
Do you have a party bridge rotation for 20 Couples (40 players), for eight months, everyone playing each month, with 4 couples at 5 different locations each month.

Thank you

Answer
Hi,

This is the best I can do.

Assign each pair a number 1-20. The chart below lists the four pair numbers that are assigned to each of the five locations for each month.

Month    Location #1   Location #2   Location #3   Location #4   Location #5

1       1,10,3,11     6,16,5,19     9,18,4,8      13,17,14,2    12,15,7,20
2       2, 1,4,12     7,17,6,20    10,19,5,9      14,18,15,3    13,16,8,11
3       3, 2,5,13     8,18,7,11     1,20,6,10     15,19,16,4    14,17,9,12
4       4, 3,6,14     9,19,8,12     2,11,7,1      16,20,17,5    15,18,10,13
5       5, 4,7,15    10,20,9,13     3,12,8,2      17,11,18,6    16,19,1,14
6       6, 5,8,16     1,11,10,14    4,13,9,3      18,12,19,7    17,20,2,15
7       7, 6,9,17     2,12,1,15     5,14,10,4     19,13,20,8    18,11,3,16

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.
