Greek Grandmaster Stuns World Champion in Historic Chess Upset

Greek Grandmaster Nikolas Theodorou scored a historic upset Wednesday, defeating reigning world chess champion Gukesh Dommaraju of India at the prestigious FIDE Grand Swiss tournament.

The victory marks the first time a Greek player has ever defeated a sitting world champion in a competitive match, a major milestone for the country's chess community.

The FIDE Grand Swiss, held this year in Uzbekistan, is one of the sport's most difficult events. It serves as a key qualifier for the Candidates Tournament, which determines the next challenger for the world title that Dommaraju currently holds.

The win by Theodorou, who is from Rethymno, Crete, is being hailed as a breakthrough moment that raises the profile of Greek chess on the world stage.
