It continues to storm around the American chess player Hans Niemann. To take a quick summary: Since then the debate has raged, and Carlsen himself has promised an explanation at the start of this week. PROMISES TO SPEAK OUT: … but not about everything. Photo: ARUN SANKAR / AFP On Sunday evening, a new analysis was published by the French chess profile Yosha Iglesias on Twitter. She has gone through a number of specific moves in several long chess games using the analysis tool of ChessBase – a database program for chess games. – Before I looked at this data, I really didn’t know what to think. I was more inclined to think that Hans had cheated, but I wasn’t sure at all. The data analysis shocked me, says Iglesias to news. – Humans don’t have games like that. In the video analysis, it is said with this model that world number one Carlsen is about 70 percent accurate compared to the computer’s move suggestions. The video causes news’s chess expert Atle Grønn to react. Photo: Screenshot, Twitter – In her model, Niemann scores 100 percent around 10 times. The only other one that comes close was at 98 percent, and he was caught cheating. I have to take her word for it, because I have not done the data analysis myself, Grønn continues to news, and points out that Iglesias “can do this with data analyses” and that the model is well known. – Magnus does not have parties like that. Humans don’t have parties like that. And then she shows that Niemann has many parties like that during his career, says Grønn. The American himself has denied that he has cheated. He has nevertheless admitted that he was banned from Chess.com after cheating online twice as a 12- and 16-year-old. – No doubt The Ukrainian Fide champion Andrii Punin has made a similar analysis as Iglesias previously. – I thought it was convincing, but I think this video is even clearer. It takes time to get people to accept, longer than I thought it would take, says Grønn. CLEAR SPEECH: Atle Grønn has no doubt that Hans Niemann has cheated. Photo: Fredrik Hagen / NTB Iglesias has also been surprised in the case. – That no one was aware of this shocked me even more. I’m just a nerdy Fide master, but neither a mathematician nor an anti-cheat specialist. I just wanted this data to be public knowledge and for experts in particular to discuss it, she says. – But for me there is no doubt anymore. And even if some experts may find a flaw in my video, I’m sure it won’t change the overall reasoning or conclusion, Iglesias adds. Thought everything was normal news spoke to Professor Kenneth Regan last week, which Iglesias refers to in his Twitter post. He is known as the great expert on computer cheating in the chess world, and is used by the International Chess Federation (FIDE). He has analyzed all of Niemann’s parties over the past two years. – Everything is completely normal, he told news. RECOGNIZED PROFESSOR: American Kenneth Regan. Photo: news Grønn believes that when many parties are without cheating, the average will be normalised. – Here you look at the moves and not just the parties, and it is not the case that Niemann cheats in all parties, and this means that he is not included in the large qualitative analyses, Grønn explains. – At Regan, there are only numbers, and objective analysis is great, but sometimes you can use common sense as well, continues the chess player. Grønn singles out one particular game between Niemann and Abhimanyu Mishra from 2020. – This video analysis shows the moves, and relatively strong chess players at my level only stiffen when we see them. I haven’t seen people make moves like that. He feels certain that Fide will look into the matter, especially since it has become so big – and because Magnus Carlsen is involved. Grønn also insists that Carlsen has known what he has done in what has turned into a major chess drama. – I have known him for 20 years, and he has always been extremely well informed, points out Grønn.
