In the Netflix documentary 'Untold: Chess Mates,' released globally on April 7, 2026, Hans Niemann reflects on the significant cheating scandal that emerged in 2022 following his unexpected victory over world No. 1 Magnus Carlsen at the Sinquefield Cup in St. Louis, Missouri, USA. Niemann, then 19, had entered the tournament as a last-minute replacement and shocked the chess world with his win. Shortly after, Carlsen withdrew from the event and suggested that Niemann may have cheated, leading to widespread controversy. Niemann stated on social media, 'I never received an apology. Let that sink in,' highlighting the impact of the allegations on his reputation. He has previously filed a $100 million lawsuit against Carlsen, grandmaster Hikaru Nakamura, and Chess.com, which was dismissed after a settlement. Although Niemann has admitted to cheating in online games during his youth, he firmly denies any cheating in over-the-board play, a stance he reiterates in the documentary. Despite the legal resolution, tensions remain high between him and prominent chess figures.
