\n\n\nTitle Tournament: Tianyuan Nines Title Tournament 2020\n\nNote:\n- Bots and use of AI are prohibited in this tournament and violators will be disqualified.\n- If you are seeing bigger board numbers like 'Board 6', it's because in the first 5 boards the assignment of black and white is too unbalanced and it's flagged by one or both of the Title Match players. 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?
