A fair match has never been played between humans and computers. Let's say we have a fair match:
* 100 games, to have some statistical relevance.
* One move per day, so that being tired is no disadvantage (engine can ponder all day).
* Human has access to endgame tablebases and opening databases, like the engine.
* Human can make notes and has a software like Chess Position Trainer, which can min max, like the engine.
If the human is a GM with Elo 2700+ I predict 25 draws and 5 wins for the human. The engine wins 70 games.
> Rating Stockfish against a human scale, such as FIDE Elo, has become virtually impossible. The gap in strength is so large that a human player cannot secure the necessary draws or wins for an accurate Elo measurement.
You're way off the mark here on modern engine strength.
There are many examples of top players playing Leela Knight Odds. And none of them even got remotely close to a decent record. Usually a few draws, and maybe a win. But almost entirely losses.
And that is with knight odds. Without that, zero chance.
