In my opinion, neural network engines like Alpha Zero or Leela Zero do a much better job of assessing how difficult a position is to hold. They also report the evaluation in a completely different manner, win/draw/loss probability as opposed to centipawn loss.

For example, in yesterday’s game Stockfish was often giving a drawn evaluation (0.00) where Leela Chess gave a win probability of 30%+. I was posting about this during the game.

Stockfish also uses a neural network for evaluation.

True, it’s works differently though. And Stockfish does not compute win/draw/loss probabilities as part of its eval. It converts cp to wdl using an exponential fit based stockfish vs stockfish games. So draw percentage in Leela is a lot more interesting and useful.

Yes, but at its heart it's still classical alpha-beta search rather than monte carlo.
