"there’s a trained black box evaluator that selects candidate moves, which you then select from via chess theory" You're missing my point. There is no "trained black box evaluator." There is indeed a trained evaluator, but it is not a black box. It is fully understandable. If I gave you private chess lessons, I could teach you my heuristics. And eventually you would understand them enough to be able to teach them to others. This would not be possible if it were truly a black box.
