Rotating-partner round robin: you get a new partner every round and score for yourself, not your pair. It runs in three round-robin stages into a bracket. Stage 1: three pools of 4, three rounds each (games to 11, win by 2). The field is re-pooled by standings for Stage 2 (three more rounds), then re-pooled again for Stage 3 (three final rounds). After Stage 3 the top 8 advance as four teams: the Semis pair top vs 4th and 2nd vs 3rd, and the winners meet in the Final — each a single game to 15, win by 2. Standings break ties by wins, then point differential, then points scored.
