That might be the best we can practically achieve with technology, but the point stands. If positional evaluation says one thing but an exhaustive analysis of lines finds a solution 60 moves deep, that one is going to win.
Ignore the existence of engines for a moment. The reason a particular line works, at the end of the day, is simply because it does. Just because we have heuristics that help us skip a lot of evaluation doesn’t mean the heuristics have intrinsic meaning within the game. They don’t.
They’re shortcuts that let us skip having to do the impossible. The heuristics will always lose to concrete analysis to a deep enough depth.
And that’s my point. We come up with models that give us an intuition for “why” things are a certain way. Those models are inarguably helpful toward having a gut feeling. But models aren’t the thing itself, and every model we’ve found breaks down at some deeper point. And maybe at some level things simply “are” some way with no convenient shorthand explanation.
Because of our limitations, we have to compress reality more in order to reason about it. This means we're blind to some ideas that computers are not. Just like a depth 1 chess engine can't see what's happening at depth 3 but has to make an imperfect guess.
