Here is a LiChess article that some might find interesting. :D

In fact, I believe some amateurs are actually actively ruining their chess by their misuse of engines. Seeing as how engine bars are becoming ubiquitous in chess commentary, I believe that this post must be read very carefully - now more than ever.

The endgame for computer chess will be a small program (by the standards of the time) running on cheap hardware (again by the standards of the time) receiving a random position and immediately responding with an accurate value for x in one of the following 3 formats:

1. White wins in x moves
2. Draw
3. White loses in x moves

I look forward to this. AI will deliver a good quality of truth in all things. If you currently profit from other people's ignorance, you will need to change your ways: new worlds belong to the brave, say I!
Human chess is partly about tactics and strategy, but mostly about memory

What they claim about fortress seem to be wrong
Salov, constructs a fortress that stops Korchnoi's advances



In this position, White, a former world #3, Salov, constructs a fortress that stops Korchnoi's advances. At depth 49, though, SF 14 gives a -5.45 advantage - completely winning? No! This is a fortress position in which Black cannot make any progress. All White has to do is keep the rook on the 5th rank and be careful not to allow a liquidation into a winning pawn endgame were Black to sacrifice their queen.

Also, unfortunately, the engine never reaches a stable evaluation, continuously shifting from -4's and -5's.

In the game black did not play Qe2+

https://www.chessgames.com/perl/chessgame?gid=1120758

I analyzed after Qe2+ and this time with the 5 piece tablebases and got the following analysis:

Re: Understanding Chess Engines' Evaluations

Post by Uri Blass »

What they say in example 2 about stockfish is also wrong for some latest version.

"-11.50 at depth 42? Preposterous! The position is completely closed and the position is just drawn."

My hardware is too slow to get depth 42 or I do not have enough patience so I got only depth 39 but I see a different score.
