Fractional Twosome, Twosome Fractional Solid

With the "Couples/Tandem <N/4> Twosome" concept, each Couples or Tandem group adds up their total turning action (as with Fractional Stable) until they reach the given fraction, and then become Twosome for the rest of the call.

To do things in the other order, the caller will give the Twosome concept, then a fraction, and then the word "Solid". The groups are Twosome until they reach the fraction, and then become Solid (Couples or Tandem.)

The groups can also be Siamese, Tandems of 3, Threesome, Diamondsome, etc.

The nomenclature sounds intimidating at first (and the concept wasn't adopted for a while because of this) but it is actually quite logical. The two ways of working (Solid or N-some) are done in the same order in which they are spoken. The fraction is spoken between them. Do things the first way until you reach the fraction, then do them the other way. So, for example, "Couples 1/2 Twosome" means "Couples until you have turned 1/2, then Twosome". Other examples are:

Tandem 1/4 Twosome
Couples of 3 1/2 Threesome
Siamese 1/4 Twosome
Boxes are Solid 1/4 Boxsome
Diamonds are Solid 1/4 Diamondsome
Tandem Twosome 1/4 Solid
Couples Threesome 1/4 Solid
Siamese Twosome 1/4 Solid
Diamondsome 1/4 Solid
