players,\n\nIt is the second tournament dedicated exclusively to 12 k players. This is no longer unique and unprecedented. The 8 players requested almost instantly join the first tournament. A few other players wanted to join but it was too late. \n\nThat is the reason why I proposed to you a new one. With a slight difference in format: single elimination, instead of round robin. \n\nSo this a new opportunity to enjoy an exciting and challenging tournament. Join as soon as you can to make sure that you are still 12 kyu. \n\nOnce in, please accept my congratulations: you are already quarter-finalists! Would that happen in a tournament where you have to face since the beginning all sorts of merciless dan and single digit kyu?", "schedule": null, "title": null, "tournament_type": "elimination",
