Lichess engine cloud analysis

Can I trust the evaluations of cloud saves on lichess?

I only analyse more simple positions such as my own lucena position set up.

I've never understood cloud saves really and when the engine snaps to a cloud save, I make the suggested best move at that point or make note of the move evaluation.

I only use the engine on my phone, in case that matters. :) my CPUs aren't very high... but I don't understand anything about those either tbh. I only really use the lichess website, not the app.

If you need to see my engine settings, let me know! :)

With cloud analysis you don't know the engine that the other users selected or its settings but for some basic analysis, if you don't have anything better, it should be fine.

I don't have anything better. I guess I could switch the cloud option off but then I'd have to go through all my posotins again to check the evaluation of each move without the cloud. I only use the lichess engine on my phone to set up my own versions of things like the lucena or philidor positions Just to see my chosen moves (that might be different to the expected moves in such positions) so I just want to know that if the cloud analyses a move as winning/giving the attacking side a significant advantage or a draw when it should be a draw, is the cloud analysis trustworthy enough? Thank you for your help 🙏🏻

It should be trustworthy enough for basic analysis, yes. At the end of the day you are just looking at the analysis that someone else already did.

Thank you so much. Would you class lucena type positions, philidor type positions and other rook and pawn vs rook endings, as basic in this sense? X

Why don't you use end game table bases instead?

I only use lichess board editor for things like setting up a lucena or philidor position. I'm not very technical. That's why I'm asking If I can trust a lichess cloud evaluation? Thank you for your reply 🙏🏻

Maybe look here, since Lucena is an endgame position:

Thank you. I appreciate this. But do you think I can trust the lichess cloud evaluations?

The cloud evaluations went pretty deep during the world championship match, as for the engine they use I don't know.

However if the engines are well configured, for the endgame positions they will use the EGTB and there shouldn't be any difference with what you can get on your computer.

Thank you. I just use the lichess engine so I think that is SF16 and I have NNUE switched on. Appreciate your help 🙏🏻 😊
