Other Information
Groups and Allocation of Points
Tournaments shall be classified into groups, based mainly on a computer evaluation of previous tournaments while maintaining a geographical balance, with ranking points as set out below
No points will be awarded to a player until he/she has won a round. Advancement through a bye or default in the first round, will not be equivalent to winning a round. Advancement by virtue of retirement following the commencement of a match will be equivalent to winning a round. An abandoned tournament counts as a tournament played if the player had not withdrawn before the decision to abandon was taken.
