Round-Robin (RR) Correspondence Tournaments

Goal: A flexible, "rolling-start" tournament created by the community. Management & Access Creation: Restricted to Premium Members/ (or maybe 1 active tournament per free account) (to not pollute the system with many tournaments). Eligibility: Only players with an established rating (non-provisional) may join. Capacity: 3 to 9 players. Access Modes: Public: Instant join. Public-Approve: Join request sent to owner for manual approval. Invite-Only: Entry by owner invitation only. Rating Gates: Owner can set optional min_rating and max_rating requirements. Gameplay Logic Legs: * 1-Leg: 1 game vs. each opponent (random colors). 2-Leg: 2 games vs. each opponent (1 White, 1 Black). Time Controls: Fixed options of 1, 3, or 5 days per move. Dynamic "Rolling" Start: * Games trigger as soon as the 3rd participant is joined/approved. Example: When Player 3 joins, 3 games start (1v2, 1v3, 2v3). When Player 4 joins, 3 new games start (4v1, 4v2, 4v3). Strict Exit Policy: Tournament games cannot be cancelled or aborted under any circumstances, regardless of the move count. If a player wishes to stop playing, they must Resign, which awards 2 points to the opponent and 0 to the resignee. Scoring & Tie-Breakers Primary: Points (Win = 2, Draw = 1, Loss = 0). Secondary: Sonneborn-Berger Score. Tertiary: Timeouts, Lower initial rating (rewards the underdog). Final Fallback: Random selection.
