What is the answer to Lichess Analysis Engine riddle ?? • page 1/1 • Lichess Feedback • lichess.org

The Lichess analysis engine has "NNUE" and "cloud" systems and has a lot of claims, but I realized something strange today. We all know that such analysis engines can solve the question of the famous "Georgian farmer", but in this very strange case, this analysis engine succeeds in solving the Question in some systems and in others it can not Solve the Question and as I understand it has little to do with "Windows", "CPU", "32-bit, 64-bit" and "memory".
Thank you for answering this riddle.

A bug with cloud analysis, there is quite the number of these positions.

Nf6+ Kg7 2. Nh5+ Kg6 3. Bc2+

Then suddenly from -6.7 to +4.5

In other words, every once in a while it gives a different answer, or if we have two completely similar laptops, the answer it gives on the first laptop may be different from the answer it gives on the second laptop.

If it says "Cloud" that means that it was previously run by other computers to a limited depth.

If you're running the analysis and it DOESN'T say "Cloud", then it's running on YOUR computer, to whatever depth you allow it to reach.

Different depths will give you different answers because at a depth of, say, one move, it's not going to know what the best move is. But if it's allowed to look many more moves ahead, then it will figure it out eventually.
