I am back with the chess game between the two engines!

oh very nice! that’s actually quite instructive then:

so even below +1 or -1, engine can very much win with both sides. Good to know and thank you so much for showing the game

I think it’s also worth going through the conversion technique, I might try to use that XD

It’s important to know that for example +1.00 (+100 cp) is = +1 pawn. Therefore ~–0.70 is relatively close beeing a hole pawn up. Since the engine with white was loosing, it spend surprisingly much time on every move. One time I think even more than 50 minutes. Just to try to hold the worse position. The black side played relatively fast though. Interesting, how the position affects the time management.

Edit: But they don’t win every position that is just slightly better. Older versions like Stockfish 13 for example would probably say black would already be winning. That’s because modern computers are incredibly resourceful and therefore evaluate advantages more precisely, without missing certain moves or missevaluations so often. Maybe, one day engines become so strong that they evaluate the starting position of every chess game with +0.00…

oh that's very interesting, and I suppose if the engine even has to think so long, then a human would have a really hard time in that position making it unplayable. I didn't actually take into account the time usage before because I was just using an analysis board, but it does make a difference, and quite a big one!
