In addition to the world chess champion Magnus Carlsen, who organized the tournament, Fabiano Caruana, Ding Liren, Alireza Firouzja, Anish Giri, Hikaru Nakamura, Ian Nepomniachtchi, and Maxime Vachier-Lagrave took part in the event.
The tournament received media attention as one of the few sports events during the early stages of the COVID-19 pandemic.
The tournament was structured as a series of mini-matches, consisting of four games of rapid chess, if needed followed by two rounds of blitz chess (semi-finals and final only), if needed followed by an Armageddon tie-break.
The eight players played a round robin with the top four advancing to the semi-finals.
The tournament was broadcast by Chess24.com with Jan Gustafsson, Peter Svidler, Tania Sachdev and Lawrence Trent providing most of the commentary.
