Title: 6 person double round robin pickleball
Post by: PickleballerForeve on December 27, 2015, 07:57:37 PM

Dear All:

I'm looking for Round Robin (new partner each time) for 6 people ...play with each person once, and play against different people each time (minimizing against playing against same people).....the table doesnt have a 6 person WHIST.

Any help would be appreciated.

thanks
scott

Unfortunately no balanced doubles schedule for 6 players can exist - mathematically it is impossible.  There will always be asymmetries,  for example in this schedule:

[(B E):(C D)]
[(D F):(A B)]
[(D E):(C F)]
[(B F):(A C)]
[(A F):(C E)]
[(B C):(A E)]
[(B D):(E F)]

AD never partner and EC oppose three times. The other pairs of players partner once and oppose either once or twice.
