The Golden Lemon Cup is designed to strengthen our community while giving everyone the chance to gain valuable experience against opponents of appropriate strength. Here, every game should feel fair, engaging, and worth learning from.\n\nUsing the McMahon format and played without handicaps on the 19×19 board, the tournament encourages balanced matchups and thoughtful, strategic play. We are also using slightly accelerated correspondence time settings to keep games active and engaging—so players are encouraged to actually play rather than endlessly “kick the can down the road.”\n\nWhether you're here to improve, test your skills, or simply enjoy the beauty of the game, this is a space where progress and fun go hand in hand.\n\nLet’s have fun, grow stronger together, and share great games. May your moves be bold, your reads be clear—and may your stones find their perfect place!","schedule":null,"title":null,"tournament_type":"s_mcmahon","handicap":0,"rules":"chinese","time_per_move":45251,"time_control_parameters":{"system":"fischer","time_control":"fischer","speed":"correspondence","pause_on_weekends":false,"time_increment":43200,"initial_time":259200,"max_time":259200},"is_open":true,"exclude_provisional":false,"group":{"id":14970,"name":"Golden Lemon Cup","summary":"","require_invitation":false,"is_public":true,"admin_only_tournaments":true,"hide_details":false,"member_count":13,"icon":"https://user-uploads.online-go.com/35b380c4e57d9aed71a88bfbf4f68b13-64.png"},"auto_start_on_max":true,"time_start":"2026-04-03T01:00:00Z","players_start":4,"first_pairing_method":"random","subsequent_pairing_method":"strength","min_ranking":5,"max_ranking":29,"analysis_enabled":true,"exclusivity":"open","started":"2026-03-31T21:11:08.148500Z","ended":null,"start_waiting":"2026-03-31T21:10:50.417615Z","board_size":19,"active_round":1,"icon":"https://user-uploads.online-go.com/35b380c4e57d9aed71a88bfbf4f68b13-15.png","player_count":100,"ranked":true},{"id":50846,"name":"Julko's Mini Tournament XXII","director":{"id":15530,"username":"Julko","country":"pl","icon":"https://user-uploads.online-go.com/71fa797ba41fd26c92f7ed5fda17613a-64.png","ratings":{"version":5,"overall":{"rating":848.9151935407727,"deviation":66.99361121114354,"volatility":0.05927561375061667}},"ranking":11.124987819220006,"professional":false,"ui_class":"supporter"},"description":"Just for fun!","schedule":null,"title":null,"tournament_type":"roundrobin","handicap":0,"rules":"chinese","time_per_move":89280,"time_control_parameters":{"system":"fischer","time_control":"fischer","speed":"correspondence","time_increment":86400,"initial_time":259200,"max_time":604800},"is_open":true,"exclude_provisional":true,"group":{"id":78,"name":"OGS Mini Tournaments","summary":"The home for all of the old OGS mini tournaments","require_invitation":false,"is_public":true,"admin_only_tournaments":false,"hide_details":false,"member_count":386,"icon":"https://cdn.online-go.com/5.1/img/default-group-v5.svg"},"auto_start_on_max":false,"time_start":"2019-08-08T03:00:00Z","players_start":3,"first_pairing_method":"slide","subsequent_pairing_method":"slaughter","min_ranking":5,"max_ranking":38,"analysis_enabled":true,"exclusivity":"open","started":"2019-08-08T03:00:35.820891Z","ended":"2019-09-10T15:17:10.824883Z","start_waiting":"2019-08-08T03:00:35.230578Z","board_size":19,"active_round":null,"icon":"https://cdn.online-go.com/5.1/img/default-group-v5.svg","player_count":3,"ranked":true},{"id":48322,"name":"Fast Cor. 9x9 10player R-Robin.
