Anyone wishing to claim successive titles must qualify and compete normally.\n\n### Overview:\nThis tournament uses the [Site 13x13 Ladder](https://online-go.com/ladder/314) for it's preliminaries.\n\nTo have a chance of competing in this tournament you need to be in the top 30 of the Site 13x13 Ladder on the 9th Jan 2020. 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 9th of January 2020, 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. Bots are ineligible for this tournament.",
