If these extra boards contributed to a more balanced distribution of black and white, we will cancel the 5th (and the 4th) board and use the result in the new boards. For example: if in Board 1~5 player A is always assigned Black, and in Board 6 and Board 8, player A is assigned White while in Board 7, player A is assigned Black again, we will use the results from Board 1, 2, 3, 6, 8, instead of Board 1~5. This is a workaround to balance the black-white assignment in the title match as on OGS, there's no way for a tournament director to assign the color of individual games.", "schedule": null, "title": null, "tournament_type": "elimination", "handicap": 0, "rules": "chinese", "time_per_move": 107733, "time_control_parameters": { "system": "fischer", "time_control": "fischer", "speed": "correspondence", "pause_on_weekends": true, "time_increment": 86400, "initial_time": 604800, "max_time": 604800 }, "is_open": true, "exclude_provisional": true, "group": { "id": 515, "name": "OGS Title Tournaments", "summary": "Would you like to compete with hundreds of players in epic tournaments and become the Honinbo, Meijin, Kisei, Tianyuan, Mingren or Kuksu?
