Daniil Dubov will not be playing the 7th round of the Tata Steel Chess Tournament today. Due to a COVID-19 contamination in his inner circle, the tournament organisation (after consultation with the chief arbiter) has asked Dubov to play wearing a face mask, in order to protect his opponent, Anish Giri. Dubov did not show for his match, which means that he has lost his game by forfeit. Dubov has indicated that he refuses to play wearing a face mask as a matter of principle. Dubov himself tested negative in a quick scan test. He has also undergone a PCR-test, of which the result is likely to come in this evening.
