91% Accuracy? Are You Mocking Me?

I played enough blunders to lose 6 games. SIX GAMES. Accuracy 91? I don't think so.

I don't need your pity analysis tool

lmao

Lol 

Actually, this is pretty common. There are several games of mine where I haven't played a single blunder but still have had an accuracy of less than 85%. The chess.com analysis mainly uses number of best moves for calculating accuracy.

Also, you had a long game. So you got the 90% accuracy just because you played 45 so called 'BEST MOVES' which are engines top choice

LOOL

These engine reports are obviously complete utter rubbish.  The move by move engine evaluation is a much better gauge of move strength. 

Yeah, honestly. I feel bad for whoever pays solely for the analysis. It's a joke. 

I had no idea- I was wondering why my accuracy was inconsistent - sometimes really low and then high. When you go through the analysis report, are the suggestions accurate?

Nobody here's any better than the computer. It's absolutely fine for whatever it is you analyse in your games, and I very much doubt anyone here could beat the computer at the level it reads moves. People just don't understand how it works because they don't bother reading about it so they'd prefer to have a moan.

Does accuracy changes on a greater depth? Could you test that out? Because as you say, these swings are crazy for a 90+ accuracy game.

hi

yo

Accuracy reports are garbage. Don't go by them.

Go to the Details tab. There's a best move % stat there which is usually far lower than the accuracy displayed on this tab. 

I dont care about the "accuracy" stat from this site. When I analyse some of my games I load them up on Chessbase and run an analysis against Stockfish 12. After that, I do an infinite analysis on key positions I feel were key points during my games, especially those in which I was not very sure if my move was right.

Yes. But with a major flaw. When adding up the totals in the analysis of best, excellent and good moves -

often they do not match the totals given in Report.

Sometimes by a substantial amount. I sent a bug report and after weeks received a response. Thanks for bringing this to our attention. The proper department has been notified of this obvious discrepancy. An upgrade is in the works.

Heard that for how long now ? 

A recent game of mine had a position that the computer evaluated as either -3.75 or -1.34, depending on whether we arrived at that (exact same) position via the line played in the game or via an alternative move order.

That's nearly 2.5 pawns difference, in the exact same position, same side to move, same computer evaluating. Go figure.

The tool creates widespread confusion, misunderstanding and mistrust. It’s existence gets justified by the ease of use for new players to check their blunders. All the while Staff is aware of it’s many irregularities and pitfalls. On top of that they have to deal with all the false cheating reports due to Accuracy score- taking up valuable resources and time.

To get such things through their thick skulls can take years.

The tool needs junking. Start over. Attempts at any revision is doomed to further failure. A fix here a fix there .... will never solve the issues as the tool has major flaws, always inconsistent. Run it one time to see one result... run it again to see another.

The depth of analysis is shallow. It often gives a move as best and then quickly changes it’s mind to a blunder after the next move flip flopping back and forth between best, excellent or good or mistakes. How it arrives at an Accuracy score I think has the programmers themselves stumped !

lol yeah the chess.com accuracy system isn’t always too good
