The format of the tournament for 2021 has been adapted to meet the COVID-19 guidelines and measurements from local authorities and the RIVM. The Tata Steel Chess Tournament is normally visited by several chess enthusiasts. It is an opportunity for them to see the top of the chess players in action at close quarters. The organisation would like to offer this opportunity to chess enthusiasts in 2021 as well. However, this will have to be in an adapted format. The possibility to allow visitors to the Tata Steel Chess Tournament depends on the measurements of the local authorities at the time of the start of the event.
