The engine knows better... right?

Hello again forums! Might anybody know why, despite making just one inaccuracy, one mistake, and four sub-optimal moves, the engine gave me just 70.7 percent accuracy in my last blitz game? I know the four sub-optimal moves (what the engine considers "good") played a role, but I've had more of those moves, more mistakes, and even a blunder in a game where I scored much higher accuracy. Were these more critical mistakes? I'm not sure.

Because the diagram won't tell, my moves h5, Bxh6, Rfe8, and Nf2 were considered "good," which I get, because there were obviously better moves. O-O was considered an inaccuracy, which I realized right as I did it, and g6 was a mistake, giving white "a significant advantage". My opponent did not capitalize on it, though.

If anybody would do me the courtesy, I am also curious if this is how I should be playing for my current blitz rating of 800 (not default, just rather mediocre with the 3-5 min. time control). Am I playing at, above, or to what would be my horror, below 800 ELO? I've only reached that number recently, playing around 690-700 for a while previously.

Any help or feedback on this would be greatly appreciated!

That’s nice to hear! I’m 970 rapid and don’t always (or usually) play blitz like I’ve got 10 minutes, but I guess I did this time. It’s never crossed my mind that I was underrated. I appreciate you man

Just found that you’re 1590 rapid! Interested in an unrated daily game? I could probably learn a few things.

You have to understand what an engine is and what its limitations are.

An engine is a tactics master. It doesn't care that this book move is better for X positional reason, or this piece was moved for this idea. It just cranks out tactics, so sometimes their advice is weird or even wrong for the move you want.

Secondly, chess.com's computer kinda sucks. You can see blatant cheaters crank out perfect game and they won't be rated 100% by chess.com, because the cheater's engines are superior to chess.com's engine.  So even a person playing the best moves can be rated as a mistake.  

And lastly, computers have perfect vision, but humans don't.  Every time a computer finds a mistake or a blunder, you have to ask yourself if your opponent could have found it.  If you honestly don't think they could have, then I would consider the computer wrong.

Yeah I think I may give the engine too much credit sometimes. I hadn't thought about how difficult it would be for my opponent to find a mistake of mine, though. I'll keep that in mind.

You must know to give importance to the engine according to your own rating and level. For example , if the engine points out that a certain move was a mistake because it missed a 6 move sequence that would have made the position better , a 2000 might bother about it . A 1000 need not. However suppose it shows you a 2 or 3 move line that could have won a piece or a pawn , than the 1000 guy certainly needs to look at it.

Engine is goofy

I will also keep that in mind. I'm starting to realize that the engine can help, but like you said, I should pay more attention to the simpler lines and tactics that I can use next time I play.

to clarify i meant to reply to Anonymous_Dragon there. didn't see your post.

Okay so something interesting happened. I went back to look at the game I played with 70.7 accuracy, and the computer changed a few things. It gave me a new (and probably more appropriate) 83.6% accuracy, changed O-O to a good move, Rc8 to a mistake for some reason, and trading my dark-squared bishop on h6 to a mistake, which makes sense. The engine was a little too quick, it seems. I've heard of this happening before, so I thought I'd put it out here.

no because that's a weaker engine

Chess.com accuracy counter is a joke. I had a game were out of 24 moves at least 15 moves were top 4 engine moves and I only got 56.4%. Its a joke

You need to learn school math .

A LOT DEPENDS ON WHICH ENGINE?

The chess.com engine that  gives accuracy is very very poor.

I can tell because you're like the 30th person who's told me that. (I mean that in a joking way, i can''t find the laughing emoji)
