Some important clarifications have been made in the qualification systems for the FIDE Chess.com Grand Swiss 2021 and the FIDE Chess.com Women's Grand Swiss 2021. According to the tournaments' Regulations, the system was to be clarified by March 1. Consequently, article 2.1.A. of the regulations has been updated:
A. Average FIDE Rating of the 12 monthly lists starting from 1st July 2020 to 1st June 2021.
One hundred (100) players will qualify by their average rating. For the purpose of deciding one hundred qualifiers by rating, the average ELO from the twelve standard FIDE rating lists from 1st July 2020 to 1st June 2021 is used. In case of equality, two decimals are taken into consideration. If the numbers are still equal then the total number of rated games in all 12 standard rating periods shall be decisive: the player with the greatest number of games qualifies.
FIDE Chess.com Grand Swiss 2021 and the FIDE Chess.com Women's Grand Swiss 2021 will be held from October 25, 2021 to November 8, 2021 in Villa Marina, Douglas, Isle of Man.
