@Bxf7wins I appreciate your thoughts but you would engender more trust if you actually addressed the larger issue at concern here, which is potential human bias in the cheat detection system.
Just saying it's obvious based on the public dataset alone doesn't set up a lot of room for people to feel good about the future of online chess. Have you ever heard of "pessimistic meta induction"?
Instead of assuming you're always going to be able to spot a cheater from the outside looking in, it would be interesting to consider the possibility that, just like machines can now fake being human, we humans are also evolving to be better able to calculate like machines.
It's not a matter of if, or when, it's happening. It's happening right now, and if your plan for not giving cheaters an edge hinges on them being lazy enough to not google a book written decades ago then it's not gonna offer much solace to the next false-positive.
Because you have the experience and expertise to look at this issue with a degree of certainty I encourage you to also look at it from a degree of humility. Even the model for an atom is constantly in question. If we're struggling to understand our universe on such a fundamental level, then what's to say with certainty that statistics themselves are always proof of only one thing?
