> [1]Tangentially, this induces an obvious concern about cheat and cheat-detection arms races. A clever cheater might scrutinize this report and refine their cheating plan. For example, they might recognize the need to use a second device (such as a phone) to cheat. They might use the data corpus presented in this report to establish limits on how often they use chess engine moves per game, and they might manage their ratings progress over time carefully, so as to stay in acceptable ranges of engine move correlation, rate of improvement, etc.

Important point I'd say. I really can't shake my personal feeling that chess as a sport is just simply dead, especially as an online e-sport. Especially in combination with the possibility that there's plenty more cheating that they're not catching/detecting.

Taking this report along with Hans's admission to only cheating twice, for example, and accepting Chess.com's assessment as accurate, it would seem that Hans's mistake was to confess only to the instances of cheating that he thought had been caught. Which indicates the mentality and experience involved where the actual game is not getting caught and many, just as Hans was before beating Magnus, are playing it successfully.
