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", "handicap": 0, "rules": "japanese", "time_per_move": 88451, "time_control_parameters": { "system": "fischer", "time_control": "fischer", "speed": "correspondence", "pause_on_weekends": false, "time_increment": 86400, "initial_time": 259200, "max_time": 432000 }, "is_open": true, "exclude_provisional": true, "group": { "id": 655, "name": "Romania", "summary": "", "require_invitation": false, "is_public": true, "admin_only_tournaments": false, "hide_details": false, "member_count": 30, "icon": "https://cdn.online-go.com/5.1/img/default-group-v5.svg" }, "auto_start_on_max": true, "time_start": "2025-02-06T07:00:00Z", "players_start": 8, "first_pairing_method": "random", "subsequent_pairing_method": "random", "min_ranking": 18, "max_ranking": 18, "analysis_enabled": true, "exclusivity": "open", "started": "2025-02-06T17:45:27.652285Z", "ended": "2025-07-06T17:36:17.175922Z", "start_waiting": "2025-02-06T17:45:27.520336Z", "board_size": 19, "active_round": null, "icon": "https://cdn.online-go.com/5.1/img/default-group-v5.svg", "player_count": 8, "ranked": true } ] }
