Knockout event — places follow from the bracket: shared places (e.g. 5-8) are teams eliminated in the same phase; an unplayed decider leaves the place shared. Click a team for its players below.
Cumulative Butler by cross-IMPs. Each round's per-board Butler = mean cross-IMP vs that round's full field (raw / (N−1)), rounded to 0.1. Cumulative = sum of a player's per-board Butler over ALL played rounds ÷ total boards played, rounded to 0.01.
Rounds included so far (3 of 3): R1 R2 R3. Columns QF·1… = each player's Butler total in that stanza (each knockout phase is played in segments); they sum to Total.

Top 12 in each metric — or, with a team picked as ★ My team, that team’s players. Open the full player-statistics page for every player, sortable by any column — including an opponent-adjusted (strength-of-schedule) Butler. Double-dummy is idealised — the true best play needs all four hands — so read these as tendencies, not verdicts.
