Daniil Dubov will play in the 8th round of the Tata Steel Chess Tournament today. He did not play yesterday, because he refuses to play wearing a face mask as a matter of principle. After someone in his inner circle had tested positive, the organisation had asked him to play while wearing a face mask. After a negative quick scan test the result of the PCR-test also came up negative last evening. A second quick scan test also came up negative today. This means that he can sit down behind the board today.
