How the 12-team chess double elimination bracket is built
12 is not a power of two, so the bracket is padded to 16 slots and the top 4 seeds skip round one with a bye. Everyone gets two lives: losers from the winners bracket drop into a 6-round losers bracket. The grand final is 22 games in, and if the losers-bracket finalist wins it a reset game is played, for 23 games in total.
First-round matchups
Standard seeding puts the strongest seed against the weakest: 8 v 9, 5 v 12, 7 v 10, 6 v 11. Seeds 1–4 wait for round two. List your teams strongest-first in the generator and the seeding is applied automatically.
How long does it take?
With 60-minute games, 23 games take about 23 hours on one board and 11.5 hours on two — but rounds can't overlap, so the last rounds always run one game at a time. Pro's scheduler enforces that ordering when it assigns dates, start times and boards.
Chess rules that affect the schedule
Club round robins use 1 point for a win and ½ for a draw. Colors (white/black) alternate — the home/away column in the schedule can be read as white/black.
Tie-breakers: Sonneborn-Berger, then direct encounter, then number of wins.
Organizer tip: Read "home" as white. The generator balances home games so colors are as even as possible.
