The Karl Jobst Theorem

The idea that "having a better understanding of a game makes you even more likely to cheat", coined by video game speed running Youtuber Karl Jobst.

Guy 1: There's no way Billy Mitchell could have cheated on Donkey Kong, he's so good!
Guy 2: The fact that he is so good at the game means he knows how to cheat better at it, it's a textbook example of the Karl Jobst Theorem.
