My bad. I meant 25.
By the way, are engines always correct regarding imprecision? That, from a human point of view regarding chess matches.
Computer Analysis - Why does it mark inaccuracies?
Sort:
"Inaccuracy" is the least serious type of "less-than-perfect" move. All it's saying is that your position would be slightly better by taking its advice, but not much. A worse deviation would be the "mistake" or "blunder."
If can use Windows programs, download and install the freeware Lucas Chess, then use the share icon to save you chess.com analysis to a pgn file on your computer. Load the pgn file into Lucas Chess and have Stockfish analyze it at a setting of 20-ply and 15 moves (you can download Stockfish 10 and Lucas will accept it as an External Engine if the Stockfish version included with Lucas isn't good enough for you.).
After you analyze the game, you'll see a listing like the one below. You can click on any move and a window will appear showing the top 15 moves (if there are that many legal moves), what continuation was best with each one, and how it rated each one. In some cases, you can see that you'd have been better off choosing a different move. Often the difference between the "best" move and your move is 0.1 to 0.3 and basically means either one is equally good.
Hi. After my matches I always analyse my games with the computer, to improve my overall performance and to see where I could improve and what stuff I have missed.
Now I have a question, though: Why does the engines mark some of my moves as "inaccuracies", giving me "better" moves, even though to me it doesn't look like my move was bad?
Take an example at this match. Stockfish engine marks a single error (which I noticed [I could kill the pawn on B 7 with my Bishop and then take a rook through my pawn on move 24]), but it also marks some inaccuracies, giving me "better" moves. Although I understood why it gave me such moves, I still don't get why mine were marked as inaccuracies, as they look to me like good moves anyway?
If you could analyse the inaccuracies and tell me your opinion, that would be much appreciated! Thank you a lot.
