I had the impression that in time my knowledge of go has improved. That was not only an impression. I started as 13 kyu, but for a long time I was playing on the plateau of 12 kyu. Even better, for a few months I reached the level of 11 kyu, and occasionally even 10 kyu. But over the last two months I was a “victim” of a black series of losses, losing even to players that I have beaten at the beginning of my “career” and slipping down to an inevitable 14 kyu. I do not know exactly why, but I suspect that one of the reasons was playing in tournaments with players with a way too high a rank.\n\nThat is why I am proposing you a nice, relaxed and friendly tournament where everyone is almost equal in rank (13 to 15 kyu) and everyone has a chance to win and it is not a pre-destined victim.\n\nPlease come on board, for this experiment, which will allow us to continue improving our Go skills and also learning more about ourselves.\n\nThank you in advance.\n\nPS: This is the first tournament I create, so I do apologize for any possible errors and misfits.\n\nPetru","schedule":null,"title":null,"tournament_type":"double_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":259200},"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":"2024-08-17T10:00:00Z","players_start":16,"first_pairing_method":"random","subsequent_pairing_method":"random","min_ranking":15,"max_ranking":17,"analysis_enabled":true,"exclusivity":"open","started":"2024-08-19T14:56:02.912057Z","ended":"2025-05-16T06:21:28.609695Z","start_waiting":"2024-08-19T14:56:02.664448Z","board_size":19,"active_round":null,"icon":"https://cdn.online-go.com/5.1/img/default-group-v5.svg","player_count":16,"ranked":true},{"id":110448,"name":"13x13 9/12/66","director":{"id":984992,"username":"Tonmai Inw of year2024","country":"th","icon":"https://user-uploads.online-go.com/bdd14570ebd42ca882afc6bd5e3be28e-64.png","ratings":{"version":5,"overall":{"rating":1106.7386412361734,"deviation":61.679833429131634,"volatility":0.0602603930083794}},"ranking":17.264680735213798,"professional":false,"ui_class":""},"description":"13x13 9/12/66","schedule":null,"title":null,"tournament_type":"swiss","handicap":0,"rules":"japanese","time_per_move":10,"time_control_parameters":{"system":"byoyomi","time_control":"byoyomi","speed":"blitz","pause_on_weekends":false,"main_time":30,"period_time":10,"periods":5},"is_open":true,"exclude_provisional":false,"group":{"id":5893,"name":"Go Family","summary":"","require_invitation":false,"is_public":true,"admin_only_tournaments":false,"hide_details":false,"member_count":150,"icon":"https://user-uploads.online-go.com/69dc5c9576b388c1fc86c857114ab798-64.png"},"auto_start_on_max":true,"time_start":"2023-12-09T08:00:00Z","players_start":4,"first_pairing_method":"slide","subsequent_pairing_method":"slide","min_ranking":5,"max_ranking":38,"analysis_enabled":true,"exclusivity":"open","started":"2023-12-09T07:38:50.966127Z","ended":"2023-12-09T07:40:03.307043Z","start_waiting":"2023-12-09T07:38:50.896150Z","board_size":19,"active_round":null,"icon":"https://user-uploads.online-go.com/69dc5c9576b388c1fc86c857114ab798-15.png","player_count":4,"ranked":true},{"id":48227,"name":"Training Ground Class 6 June 2019","director":{"id":87790,"username":"WiseBear","country":"ru","icon":"https://user-uploads.online-go.com/87e96797186d0c4042434c29195d8f12-64.png","ratings":{"version":5,"overall":{"rating":1104.0021061102002,"deviation":62.08308547890164,"volatility":0.06028822213904829}},"ranking":17.207368885691388,"professional":false,"ui_class":""},"description":"If you want to be stronger, then you should often play with those who are a little stronger than you.
