How a rotation algorithm lets every padel americana player partner everyone

An americana is a social padel format in which partners change each round so players meet as many others as possible. Scheduling this becomes tricky with an odd number of players and limited courts, as with seven players on two courts. The author's TypeScript approach borrows the round-robin circle method, rotating players so that over a full cycle every player partners every other player exactly once. An extra placeholder slot handles odd player counts, and placing it in the pinned position ensures each real player sits out in turn. Because the rotation's length depends on the number of players, the schedule repeats after that many rounds, and resting pairs are balanced to spread byes fairly.
