There is a video explaining how Hans played ten 100% games (his moves matching 100% moves of what an engine would do) in the last three years and a lot of >90%:

For reference, Magnus at his best does a 70% match with engines, and between 70-75% is historically enough to earn you the World Championship. This guy is consistently over 80%, come on.

Reminds me of Lance Armstrong: a mediocre 90's cyclist that suddenly becomes the best in history, in such dominant fashion that I think everybody suspected something, but without proof you cannot do nothing about it.

And here's Hikaru's video examining the Yosha's evidence by comparing it to games he and other GMs have played. There's definitely something going on with Hans having so many >90% games, when the other higher rated players struggle to 80%.

Exactly. And Nakamura takes in that video the position that 100% is the perfect game. It's not. 100% means you made exactly the same moves an engine would made, but engines sometimes have two best moves with only a minimal preference for one of them. Those decisions are the ones that made Nakamura best games "mere" 80'ish%, in less important moves he did the second bests according to the engine.

If you are a top player and cheat, you would only require a couple of decisions here an there in complex positions, and the games would be still at roughly 75%. But if you don't fully understand the line, or you're not in the zone, and the engine suggest something crazy (but winner) you need all the following moves.
