MBL players create teams who play in a round robin tournament from December to June, followed by a final. If at least 10 teams subscribe, the tournament is flighted: A (3000+ average MP per player) and B; otherwise, the tournament is open. The winning Flight A team plays a Montreal-Toronto final at the end of the season.
This is a good occasion to refine your team play with 26-boards matches in a friendly atmosphere (serious, but not too serious).
