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?
