This time the championship is expanded to 3 groups, each consisting of a round-robin tournament. Each tournament is equivalent and the winners, runners-up and two best third placed players of each tournament will qualify to a final-8 knockout tournament.\n\nIMPORTANT NOTES\n\nIf you do not manage to join a specific group you can join one of the remaining ones if there are still vacant places.\nPlayers with ranking between 10-25 kyu are allowed to join the tournament.\nEach player should join a SINGLE group. If someone joins two or more groups, the tournament manager will remove him/her automatically.", "schedule": null, "title": null, "tournament_type": "roundrobin", "handicap": 0, "rules": "chinese", "time_per_move": 88320, "time_control_parameters": { "system": "fischer", "time_control": "fischer", "speed": "correspondence", "pause_on_weekends": false, "time_increment": 86400, "initial_time": 172800, "max_time": 432000 }, "is_open": true, "exclude_provisional": true, "group": { "id": 4957, "name": "Beginners 9x9", "summary": "", "require_invitation": false, "is_public": true, "admin_only_tournaments": false, "hide_details": true, "member_count": 32, "icon": "https://cdn.online-go.com/5.1/img/default-group-v5.svg" }, "auto_start_on_max": false, "time_start": "2020-12-23T12:00:00Z", "players_start": 4, "first_pairing_method": "slide", "subsequent_pairing_method": "slaughter", "min_ranking": 5, "max_ranking": 20, "analysis_enabled": true, "exclusivity": "open", "started": "2020-12-23T12:00:34.878164Z", "ended": "2021-01-28T19:30:24.335549Z", "start_waiting": "2020-12-23T12:00:33.869344Z", "board_size": 9, "active_round": null, "icon": "https://cdn.online-go.com/5.1/img/default-group-v5.svg", "player_count": 10, "ranked": true }, { "id": 70434, "name": "Correspondence 9x9 RoundRobin 2021-01-23 19:00", "director": { "id": 4, "username": "matburt", "country": "us", "icon": "https://secure.gravatar.com/avatar/1dff84686f829e8ef90e2e123f1baddf?s=64&d=retro", "ratings": { "version": 5, "overall": { "rating": 1125.8827017028436, "deviation": 78.19731452501959, "volatility": 0.06006087171771568 } }, "ranking": 17.66169912212786, "professional": false, "ui_class": "supporter moderator admin" }, "description": "Automatic Sitewide Tournament", "schedule": { "id": 5, "name": "Correspondence 9x9 RoundRobin", "rrule": "DTSTART:20260315T190000Z\nRRULE:FREQ=DAILY;INTERVAL=3", "active": true, "created": "2015-02-20T05:56:18.340749Z", "last_run": "2026-03-15T19:00:12.019803Z", "lead_time_seconds": 86400, "tournament_type": "roundrobin", "handicap": 0, "rules": "japanese", "size": 9, "time_control_parameters": { "time_control": "fischer", "initial_time": 259200, "pause_on_weekends": true, "max_time": 259200, "time_increment": 86400 }, "min_ranking": 0, "max_ranking": 36, "analysis_enabled": true, "exclude_provisional": true, "players_start": 4, "first_pairing_method": "slaughter", "subsequent_pairing_method": "slaughter", "settings": { "num_rounds": "3", "upper_bar": "20", "lower_bar": "10", "group_size": "3", "maximum_players": 10 }, "next_run": "2026-03-18T19:00:00Z", "base_points": "10.0" }, "title": null, "tournament_type": "roundrobin", "handicap": 0, "rules": "japanese", "time_per_move": 89280, "time_control_parameters": { "time_control": "fischer", "initial_time": 259200, "pause_on_weekends": true, "max_time": 259200, "time_increment": 86400 }, "is_open": true, "exclude_provisional": true, "group": null, "auto_start_on_max": false, "time_start": "2021-01-23T19:00:25.394746Z", "players_start": 4, "first_pairing_method": "slaughter", "subsequent_pairing_method": "slaughter", "min_ranking": 0, "max_ranking": 36, "analysis_enabled": true, "exclusivity": "open", "started": "2021-01-23T19:00:30.050747Z", "ended": "2021-02-21T03:07:15.230451Z", "start_waiting": "2021-01-23T19:00:28.665445Z", "board_size": 9, "active_round": null, "icon": "https://cdn.online-go.com/5.1/img/trophies/gold_title_9.png", "player_count": 8, "ranked": true } ] }
