91% Accuracy? Are You Mocking Me?

It also cracks me up when the report labels what may be the second "best" move as "excellent," even if it is a losing move and/or significantly worse than the "best" move.

And I'm still trying to wrap my head around "brilliancies," and how and/or why they initially fool the engine as opposed to other material sacrifices.

They aren't. It's a percentage. If you read into it wrong then that's your own fault. If someone has 90% accuracy in a 50 move game it is telling you it didn't like 10 moves. 10 moves that could be blunders. It's not a damn report card.

It’s well known the analysis thing, more accurately the accuracy thing doesn’t worth a big deal...

So if it tells you, you 10% of your moves are wrong it's not worth anything? Perhaps your interpretation isn't worth anything.

As long as you continue playing, the site makes money from "your attention."  AND, when you talk about it in a thread, still more attention is drawn to the site.

To wit -- this unfolding thread works according to the same principle.  More eyeballs on site, more $$ for site owners.

What's not to like? grin.png

accuracy also depends on move. if it is excellent or good, it lowers your accuracy even though its positive

And if I score 98% accuracy in a 30 move game which includes 1 mistake and 1 blunder what exactly is the report telling me then?

It literally is exactly that, though. It even says "Game Report" on it tongue.png It's just not as good at is as we had hoped, it seems nervous.png

Except for the half dozen blunders and a handful of mistakes and missed wins, you played pretty accurately. .. let's say about 91.3% and call it a day.

The tool calculates accuracy in comparison to the stockfish engine, the default depth is 18, that means that it’s very superficial, if you set the depth to 26 or higher if possible (takes more time to analyze tho), when the engine starts to actually get good, you will have a much more accurate accuracy calculation. I’m not sure on this but I believe it also takes into account your opponents accuracy.

No it is not. 90% in school would mean you understand 90% of the concepts. In chess 10% of your moves can EACH throw the entire game. It is what it is.

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

Start using your brain properly and probably your eyes too....I never said it’s worthless, but it doesn’t provides an efficient help, there are games with 100% accuracy with only book moves also there are games with only book moves but accuracy not more than 95%

I once blundered my queen but still got 99.1 accuracy

Resigning a winning game is also a blunder but the analysis thing won’t give it a damn

For excellent moves, the engine obviously calculates the moves further than you, even though the moves may look like losing moves at first, the engine could might see a lot of possibilities. In the case of brilliant moves, the engine depth is too low to calculate if the move is in fact the best move. If you play a brilliant move, that means you forced the engine to calculate further (resetting its depth) and if it sees that the move you played was better than the suggested move, you played a "brilliant" move. Even if it is the looks like the only option to us, the engine sees a lot more options. You could also just increase the engine depth and your moves will not be brilliant anymore, because the engine found the move itself... I hope this cleared it up a little, there probably are better explanations but this is the best I could do.
