In modern chess, engines have gotten good enough that we generally do know the top moves and humans can’t beat them. We can even numerically assess someone’s chess play with a computer, which we call “accuracy”. Obviously they can always be improved further, and there are a handful of situations where they might misevaluate, but it’s still pretty incredible.
Engines have only made chess more exciting as they have shattered a lot of old theory and helped people find a lot of new and innovative ideas. They are an incredible aid in analysis and tournament prep.
I’m honestly not sure, but I’m fairly certain it’s intentional obfuscation done for the production build. Why they think it’s so important to hide class names, I’ll never know.
