Cheating allegations 

Sinquefield Cup incident

Niemann beat Carlsen with the black pieces in the third round of the 2022 Sinquefield Cup. With this win, Niemann’s live rating topped 2700. Carlsen withdrew from the Cup the next day, tweeting a video of José Mourinho saying, “If I talk, I’m in huge trouble” Carlsen’s post and the increased security the day after his loss hinted Niemann was accused of cheating over the board, which Niemann and other analysts refuted.

Niemann played Carlsen in the Julius Baer Generation Cup. Carlsen quit after one move, stoking uproar. It’s the biggest cheating scandal in world chess since 2006’s Toiletgate. Garry Kasparov and Elon Musk have both commented on the subject.

Carlsen tweeted on September 26 that Niemann cheated. Carlsen pondered withdrawing from the Sinquefield Cup because to Niemann’s late entry. Carlsen believes Niemann cheated more often and recently than he claimed, and Niemann’s behavior during their Sinquefield Cup game convinced him to withdraw. He said he couldn’t say much without Niemann’s “clear permission” and that he wouldn’t play chess with him again.

Responses and analysis 

Tony Rich, the executive director of the St. Louis Chess Club, said in a statement that “a player’s decision to withdraw from a tournament is a personal decision, and we support Magnus’ choice.” Magnus’ decision to withdraw from the competition was a personal one. Rich explained at a later time that there was never a formal complaint submitted in writing. During the course of the competition, the Chief Arbiter, Chris Bird, issued a statement reiterating that there was “no indication that any player has been playing unjustly.” In her comments, Bird did not address the question of why additional safety precautions had to be taken after Magnus had withdrawn.

Niemann was accused of cheating in online competitions by Grandmaster Hikaru Nakamura, who claimed that Niemann had previously been banned from Chess.com for his dishonest behavior. Later, in an interview conducted after the game, Niemann revealed that he had cheated in online games when he was 12 and 16 years old. However, he categorically denied having ever cheated in an over-the-board game. In light of the incident, Chess.com has once more barred Niemann from participating in the website and any of their events, as Niemann confirmed. Daniel Rensch, the chief chess officer for Chess.com, issued a message on Twitter in which he acknowledged that Niemann would continue to be suspended until he provided an explanation for his previous instances of cheating on the platform.

Anti-cheating expert Ken Regan conducted a statistical examination of Niemann’s games since 2020, including the Sinquefield Cup game between Carlsen and Niemann, and found no evidence of Niemann’s involvement in any form of dishonesty.


Chess.com investigation and report 

Chess.com published a 72-page report in October 2022 that contained an analysis of Niemann’s games and came to the conclusion that he had likely cheated online more than 100 times, with some of those instances occurring as recently as 2020, when he was only 17 years old. According to the investigative record, Niemann admitted to the investigators that he had cheated behind their backs.

Streaming career 

Niemann competes against other chess streamers on Twitch, including Grand Masters Andrew Tang, Daniel Naroditsky, and Hikaru Nakamura, Women’s FM Alexandra Botez, and the current world champion in chess, Magnus Carlsen. Niemann streams chess both online and over the board. During his time as a streamer, Niemann worked as a coach and co-commentator for the second PogChamps online chess tournament. He worked with Twitch streamers such as XQc, Ludwig, Forsen, and Hafu, as well as the strongman and actor Hafór Jlaus Bjornsson.

During the summer of 2018, Niemann began his streaming career with sporadic appearances. In the spring of 2019, he started broadcasting his videos more frequently. Following a period of steady expansion, his audience size exploded in the early 2020 period that was marked by the COVID-19 epidemic. Niemann’s audience increased by a factor of more than 10 thanks to his nearly daily chess broadcasts, which coincided with a general uptick in activity within the chess category on Twitch.
