This is for 4-player doubles games on different maps. Depending on interest, the map may be agreed upon at least a day in advance:
4-players
Doubles
Automatic
Sunny
ideally, (though not necessarilly) also
Sequential
Escalating
Chained
There is also the possibility of forming a group of four (or six, or eight), w/ or w/o rotating partners, which may evolve into steady teams.
