Bots are ineligible for this tournament and AI assistance is NOT allowed as per the [OGS terms of service](https://online-go.com/docs/terms-of-service).\n\n### Overview:\nThis tournament uses the [Site 19x19 Ladder](https://online-go.com/ladder/313) for it's preliminaries.\n\nTo have a chance of competing in this tournament you need to be in the top 30 of the Ladder a week before the tournament begins. To guarantee entry, you need to be in the top 8 (see below).\n\nClock settings and rules are the same as for the ladder.\n\n### Qualifying / Invitational Process:\nOn the 7th of January 2021, I will take a snapshot of the ladder and send invitations to the top 8 players. Each day thereafter, I will send additional invitations equal to the number of vacancies+1 until the tournament is full, working down the snapshot-list no further than position 30. \nIf you receive an invitation, decide quickly. The top eight will get ~24hrs to decide but thereafter the additional invitees could miss out as those above make late acceptances. \n\nPlease note that if you close your invitation without accepting or declining, then a bug prevents me from reissuing it and you will need to pm me if you wish to join.","schedule":null,"title":null,"tournament_type":"elimination","handicap":0,"rules":"japanese","time_per_move":89280,"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":false,"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?
