It is even more pleasing that he beat Magnus Carlsen, reigning five-time world champion, in round 10, before advancing to the next stage.
Abdusattorov won the title along with a prize of $60,000.
He only lost one match, against the Ukrainian Anton Korobov, and tied in five others. This gave him a score of 9.5 points.
He racked up seven wins in the 13 rounds of the tournament, including in his match against the previous champion, Magnus Carlsen.
Carlsen, 31, won five world chess titles in a row, most recently the World Chess Championship in Dubai. Before Abdusattorov’s victory on Tuesday, Carlsen had had a complete stranglehold on chess’ most prestigious titles in all time formats.
