Leagues
Doubles-only, fixed-partner teams playing a round-robin season across skill-based divisions, with promotion and relegation at the edges.
- Team identity is the two core players — the partnership IS the team. A permanent change to either core player starts a new team (Ship-of-Theseus).
- Each team keeps a small player pool — two cores plus a couple of subs. Any two from the pool can play any match; rating and standings belong to the team, not the individuals on a given night.
- Multiple skill-based divisions with end-of-season promotion and relegation.
