Chelsie Monica, a Women International Master from Indonesia, achieved a remarkable victory over world chess champion Magnus Carlsen during a simultaneous exhibition at the FIDE World Rapid and Blitz Team Championships in Hong Kong. The event, held a day before the main championship, saw Carlsen take on 24 players in a rapid format. Monica was the only competitor to defeat the Norwegian grandmaster, who is widely regarded as the greatest chess player of all time.
With approximately five minutes remaining in the match, Monica moved her rook from c1 to h1, prompting Carlsen to shake her hand in acknowledgment of defeat. The 30-year-old Indonesian player reacted with a smile, a deep breath, and covered her face in disbelief. She later described the experience as both thrilling and nerve-wracking, noting that Carlsen is her idol and the best player in chess history.
After the victory, Monica requested Carlsen's autograph and posed for a photograph with him. She expressed her joy and nervousness in an interview with ChessBase India, stating, "Playing with Magnus made me happy, and yes, there was nervousness because he is the best player of all time. I hoped I wouldn't lose quickly, in five or ten minutes. I just tried to hold on, but I was lucky."
Monica traveled to Hong Kong as part of the Indonesian contingent for the World Rapid and Blitz Championships. Her achievement marks a historic moment, as she is believed to be the first Indonesian woman to defeat Carlsen in a simultaneous exhibition.
