This is really cool. Rampant cheating is the reason I completely abandoned playing chess, so nice to see something happening.
How do you cheat at chess? Serious question… there are fixed rules that govern the game, certainly a piece of software or in the human case 3rd party observer should be able to enforce them? In other words, given a list of moves, you can write a program that returns `valid` if the set of moves is allowed or `invalid` if it is not, no?
Simple: don’t play moves you discover independently, and instead use an advanced chess AI to tell you what to play. You play your opponent’s moves against an alternative AI program, and then play its moves back in your game against the human.
I don’t know why people do this. It’s not like it makes them better at chess.
