Magnus-Hans Chess Controversy

A story about how Magnus Carlsen, the world chess champion, accused Hans Niemann of cheating based on unusual behavior and statistical patterns.

"Magnus Carlsen, world chess champion, played Hans Niemann several weeks ago. Niemann beat him, but then there was controversy after where Magnus was acting sketchy. Eventually he came out with a statement saying 'I believe Hans cheated.'

There are two pieces of evidence. First, Magnus says Hans didn't look like he was trying. He says 'He beat me - I'm the greatest player in the world and I know what it looks like when people try to beat me. They're very focused and concentrated. He barely looked like he was paying attention, yet he played basically a perfect game and beat me.'

The second piece was people went back and looked at all his past games as he ranked up. They put his game history back in this chess solver engine to see how close to perfect, how close to AI did he play. The greatest players of all time have played like 62% or 72% of their moves matched what the AI would do - like perfect moves. Hans had several many games where he's at 100%, and the greatest players ever will have like no games at 100% during their rise to the top. Nobody knows how he did it, if he is indeed cheating."
