The 53rd edition of the traditional Biel International Chess Festival from 18 to 29 July will be played over-the-board with an elaborate protection concept to prevent Covid infections. The top grandmasters in the invitational will compete with transparent plexiglass shields between them. 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.
