E nevoie și de un pic de percuție pentru a nu se lungi prea mult. Partidele jucate la tablă sau pe alte servere vor fi cedate de cei ce au pierdut partida oficială. Precizez că aici vor fi create automat toate partidele indiferent de înțelegerea dintre jucători, și arbitrul nu are control asupra deciderii învingătorului. Pentru conformitate e de preferat ca în comentariul partidei de aici să se dea link către partida oficială dacă acest lucru este posibil\n\nMai jos rezultatele partidelor jucate la tablă în data de 3 octombrie la Clubul lui Codrin. \n\nCostel-Iulian Ilie 1-0 <br>\nCostel-Mihai 0-1<br>\nCostel-Sandu 1-0<br>\nCostel-Codrin 0-1<br>\nCodrin-Mihai 0-1<br>\nSandu-Codrin 0-1<br>\nSandu-Iulian Ilie 0-1<br>", "schedule": null, "title": null, "tournament_type": "roundrobin", "handicap": 0, "rules": "japanese", "time_per_move": 259200, "time_control_parameters": { "time_control": "simple", "speed": "correspondence", "system": "simple", "pause_on_weekends": true, "per_move": 259200 }, "is_open": true, "exclude_provisional": false, "group": { "id": 2993, "name": "Asociația de Go Brăila", "summary": "", "require_invitation": false, "is_public": false, "admin_only_tournaments": false, "hide_details": false, "member_count": 26, "icon": "https://user-uploads.online-go.com/97a4fe5337f2c4f846c9bfa27ce9e6c7-64.png" }, "auto_start_on_max": true, "time_start": "2018-11-11T14:00:00Z", "players_start": 10, "first_pairing_method": "slide", "subsequent_pairing_method": "slaughter", "min_ranking": 5, "max_ranking": 38, "analysis_enabled": true, "exclusivity": "invite", "started": "2018-11-08T18:36:08.278062Z", "ended": "2019-01-16T07:24:25.174323Z", "start_waiting": "2018-11-08T18:36:03.386193Z", "board_size": 19, "active_round": null, "icon": "https://user-uploads.online-go.com/97a4fe5337f2c4f846c9bfa27ce9e6c7-15.png", "player_count": 10, "ranked": true } ] }
