even if i am 800 i can sometimes get more than 90 accuracy
How good is 800 elo player

I am currently 832 rapid and the main issue i think 800-1000 face are blunders, being forked(non knight or pawn forks) and endgames. Also 1 thing you should never do is resign as you could still or maybe even win as one gome of mine i lost my queen but then my opponent blunderd a backrank mate so then i won. Also if you want to improve you should also start learning discoveries,sacrificies and other motifs. Also at theis stage you should start learning openings.
Shouldn't be blundering in one move 🤔
I disagree but ok....
Low rated players come in all forms, with all sorts of strengths. Thats why they're low rated. They arent masters at the game.
