Originally, the tournament was to be held in Nur-Sultan, Kazakhstan, however, due to coronavirus restrictions introduced by the Kazakh government prompted FIDE to change the location [1] to Warsaw, Poland.

The 2021 World Blitz Chess Championship was held in the Polish capital Warsaw, a day after the longer time-format World Rapid Chess Championship finished in the same venue, after Kazakhstan pulled out of hosting duties due to the spread of the omicron variant.

French star Maxime Vachier-Lagrave ultimately walked away with the men's blitz title.

Three players (Maxime Vachier-Lagrave, Jan-Krzysztof Duda, and Alireza Firouzja) were tied for first after 21 rounds.

Among these, the two players with the highest Buchholz Cut 1 score (Vachier-Lagrave and Duda) played a title play-off to decide the winner.
