In its medical security guidelines for the return to over the board competitions, FIDE endorses the use of masks for players and arbiters. The world federation recommends not to allow spectators and to let all players to sign a declaration that they are free of symptoms. The guidelines don’t mention play in non-closed spaces nor protective shields as they are going to be used in Innsbruck in late August or in Biel from this weekend, with large transparent plexiglass shields between the top grandmasters. In the other adult competitions broader tables will be applied in order to keep 1.5 meters distance. Long moves will require players to stand up, in order to compensate for this the increment per move is 45 seconds instead of 30. Participants that show symptoms will be refused to enter the tournament arena.
