I'm about to run a 3 session pairs event with 13 tables. Twin board sets available.
They expect 2 x qualifying to a 5 table final & Mitchell plate.

The simple way is to run a 13T Mitchell & repeat. Separate fields.
That's okay but they like & expect longer rounds.

I could run 2 x 6½ table Mitchells wth the EW sit outs at the last table in each section playing each other.
Slightly random, since the EWs might catch two strong/weak pairs at table 7.
Also has to be a one winner move, presumably scrambled. Last round enough? Last 2?
Does this move have a name?

Secondly, would your players expect or prefer 3-session cumulative?
All-play-all over 3 sessions is a little awkward with 13 tables.
How would you run the Howells & Mitch? 5 Howell + 8 Blackpool? 4H + 7+2 App? Arrowswitch the Mitchell?

Is there a better forum for asking these sort of questions?

ACBL Score (download for free from ACBL.ORG) has a 13 table / 13 round interwoven howell. There are two groups of pairs who meet only other pairs from their group with one exception. At table one a pair from group A meets a pair from group B.

First run a 13 round mitchel numbering the E/W pairs as 13+table number. Omit the first round (after pairs take their pair numbers). Those match-ups will meet at table 1 in the howell. Second session - run the interwoven howell. Everyone will have met everyone. I haven't looked in detail but I don't think you should scramble the mitchell. A better mathmetician than I should determine that.

After the two sessions everyone will have met everyone. Take the top 10 pairs as your qualifiers and put them in the 5 table (howell) final. The rest go to the Plate.

Yes I have that move keyed & movement cards for it. Not sure that all the 75-year-olds will appreciate going to
1E, 11E, 8N, 8E, 13E, 10N, 7E, 9E, 13N, 9N, 10E, 11N, 7N.
Worth a thought though. Thx.
