Legal battles, media frenzy and questions that remain unanswered
The news of Magnus Carlsen's withdrawal from the Sinquefield Cup 2022 hit the chess world like a bombshell. The day before, the world's highest-rated player had suffered a one-sided defeat against the young American newcomer Hans Niemann. Carlsen gave no specific reason for his withdrawal, instead making only vague hints on social media, but it soon became clear what the Norwegian was implying: he was accusing Niemann of computer-assisted cheating.
Let our authors show you how Carlsen tailored his openings to be able to outplay his opponents strategically in the middlegame or to obtain an enduring advantage into the endgame.
In an online tournament shortly afterwards, Carlsen refused to play against Niemann and resigned the game after the very first move. In a later statement, Carlsen became somewhat more explicit.
The incident occupied the chess world for months, and when anal beads were even suggested as a possible aid - originally meant as a commentator's joke - the story began to attract the attention of major media outlets, online platforms and television broadcasters. Chess was suddenly in the mainstream.
The story had many facets and invited a wide range of interpretations. The world's best player loses to an underdog - was he unable to lose with grace? Or had cheating really taken place? And if so, how?
Hikaru Nakamura supported Carlsen's view during his stream. The online platform chess.com published statistics on Niemann's unusually rapid rise in strength and revealing that Niemann had previously been banned twice from online tournaments for computer-assisted cheating.
However, experts demonstrated - using computer analysis and other statistical methods - that Niemann's game against Carlsen, as well as other classical games, were above any suspicion of cheating. At the very least, there were no indications of computer assistance.
Moreover, players at the Sinquefield Cup were subjected to checks for technical devices. Resourceful journalists conducted their own experiment, attempting to smuggle electronic aids into tournament halls despite the controls - and succeeded. Not in Saint Louis, but elsewhere.
Hans Niemann fought back through legal channels. He believed his reputation had been severely damaged and filed a lawsuit seeking 100 million dollars in damages from Magnus Carlsen, Hikaru Nakamura, David Rensch, Play Magnus Group, and chess.com. Part of the lawsuit was dismissed, while another part was settled out of court. The episode is over, but not resolved. Did Niemann cheat or not?

In a Netflix documentary, those involved now have their say - above all Carlsen and Niemann, but also Nakamura, Rensch and Henrik Carlsen - sharing their perspectives on events and how they experienced the controversy.
From Niemann's point of view, the incident was a conspiracy, as Carlsen and chess.com were preparing their merger at the time. Others see Niemann as a talented, though at times an erratic chess professional.
The 75-minute documentary follows the typical Netflix style. It features a mix of archival and newly shot footage. The protagonists speak at intervals, often seated in the middle of large spaces. At times, an avant-garde visual style is used: the speaker is placed far to the left or right of the frame and filmed from a low side angle.
Clips from the film, excerpts from news broadcasts and photographed magazine covers comment on the story. In the background, lively music creates a dramatic atmosphere. In the German version, the spoken text - whether voice-over or interviews - is dubbed into German and layered over the still faintly audible original audio.
Many Netflix documentaries, as well as other American productions, are made in this rather conventional narrative style.
Carlsen and Niemann recount their stories and how they experienced the controversy. After the legal dispute was settled, they also faced each other over the board again. Without giving too much away from the documentary: it is unlikely for Carlsen and Niemann to become friends any time soon.
2/25/2026 – Netflix has announced "Untold: Chess Mates", a new documentary examining the controversy surrounding Hans Niemann's victory over Magnus Carlsen at the 2022 Sinquefield Cup. The film revisits Carlsen's withdrawal, the subsequent allegations of cheating and the intense public reaction that followed. It also places the dispute within the broader context of modern chess, including the growth of online play and the challenges it has created for trust and governance at the elite level. | Photo: Netflix

For a long time the Scotch opening was considered harmless and rarely played. This changed in 1990 when Garry Kasparov successfully employed the Scotch opening in his World Championship match against Anatoly Karpov. But that was 25 years ago.

On this 60 Minutes renowned and successful coach Adrian Mikhalchishin gives simple practical tips how to neutralize and counter the Scotch.
