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.
