But a Rubik's cube solver is a single-player, solitaire game. Its fundamentally different.
Over in the "Cyborg Chess" community, people have already analyzed LeelaZero vs Stockfish. It turns out that Stockfish is far better at tactics (especially the endgame), while LeelaZero is better at opening positions (aka: Positional play).
There are numerous theories about the proper combination: perhaps using an Opening Book database for the first ~10 moves or so, using LeelaZero for moves ~10 through 30, and then using Stockfish to check for tactics (LeelaZero misses a lot of tactical options in the midgame, so double-check to make sure that LeelaZero doesn't lose a queen or something), as well as finish up the endgame.

Choosing the correct combination of tools, studying these tools and coming up with a more beautiful chess game. That's cyborg chess in a nutshell. LeelaZero and Stockfish are both superhuman in terms of play, but the cyborg can choose to use both tools to play superior compared to just a singular tool.
Anyone purely using "Stockfish only" gets beaten by opening book analysis. The dude over there with 1TB of opening book databases consisting of every losing position that Stockfish tends to play will completely own you. Same thing with LeelaZero, the opening book guy will own any LeelaZero-only player. These engines have weaknesses that can be undermined with good analysis, big-data, and a bit of custom code.
That's the funny thing about these computers: they tend to play the same. So you can build opening book databases to exploit their patterns. You require a cyborg / human to play at the "level above that" to guide Stockfish / LeelaZero away from those traps.
