Chess is a really interesting piece. It's true that DeepBlue beat Kasparov through its computational brute force calculation power; but the game tree in chess is still too deep and too wide to really compute it all the way through to the end. It relied on heuristics for which branches to explore and which branches to ignore. And those were absolutely created by human chess experts: They programmed in that a queen is worth more than rook, and countless other heuristics related to development, space advantage, piece mobility, king safety etc

And THEN came AlphaZero Chess, where nothing other than the rules of the game itself were programmed into it. All by itself thorugh reinforcement learning it learned about the relative value of pieces, but in a much more subtle way than a strict heuristic. Chess experts agree that AlphaZero Chess plays much more creative, mind-blowing moves than the traditional brute-force heuristic engines.
