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 } ] }
