Why my accuracy is so low with good moves?



the computer has a low depth analysis if you dont have premium or title so it might have a not so accurate analysis..

I'm on platinum, the depth was 18. I played worse games with many more mistakes and my accuracy was much higher.

like i put your game in lichess analysis and it showed that you have no mistakes besides the one i mentioned
No one knows exactly how accuracy works. If the computer thinks there are 3 or 4 moves that are all super close, do you get dinged for picking #3 or 4? If three moves lead to forced checkmate, do you get dinged for picking one that leads to a longer checkmate? Look at "inaccuracy" "mistake" and "blunder" instead. Those are terms that have been used in online chess for many many years, and we know what they mean. There refer to the difference in the computer's evaluation of the best move vs your move. You had only one inaccuracy (a minor error) according to the computer, and no mistakes or blunders (which are more serious errors). Thats pretty good. After an online blitz or rapid game, I look at all mistakes and blunders and try to learn from them. Thats it; thats all I do.

yes i think the computer hasnt analyzed enough for each move so it might think that some moves are worse than the move computer thinks more about and it reduces the accuracy as an result

22 moves is also short as "book" moves are not taken in to account so we are now looking at 16 moves seven of which are rated as best which is less than half.
I would not worry about the accuracy rating, I have included this game as the difference between me and my opponents accuracy was 0.9
But look I was 5 points ahead in pieces and 6.86 in the computer ratings, in these terms the games was one sided at the end. Look at the moves you make and think about strategies, don't worry about accuracy ratings.

I looked at the game, a lot of your moves weren't accurate... You simply played moves that weren't great, the engine didn't like them, they were just "ok or bad". Qa4, Bg5, a lot of moves just don't accomplish anything, waste time or don't capitalise on your opponents mistakes.
At 22 Depth the accuracy is much lower.
