100% is possible https://www.chess.com/article/view/5-perfect-chess-games
Is 99.6% accuracy the highest you can go?


I've had over 98%, over 96% etc. on legit games vs. my phone, but I usually lose & hit the back button & find another way. I'm rarely that good even against my phone but can beat most people in jail. Still, I've been looking for highest rated games according to engines for awhile & I think the chess establishment likes to keep that quiet.
I also think AlphaZero probably broke chess & Google is keeping that quiet. "

Long games with 100 accuracy is a scam. I'm not talking about if you are playing with a weaker player, but if you're playing a long game with a same rated player or a higher-rated player with 100 accuracy, you're probably… cheating. Short games may have 95+ accuracy because it has fewer moves.


The highest you can get is 99.7% for an ACTUAL game Chess game review is INSANELY bad at deciding things. it will say "that move sucks play this:" then you play that move and then game review says to play the other.
Even Look at Mikihli tal's "perfect game" after a while chess.com now is like "ehh i cant decide on 100% so ill give 99.99% 127 years later because the brilliant knight sacrifice was a "good move""
Guys, Accuracy is never matters. It is always not accurate, plus, sometimes Brilliant Moves turns out to be a Blunder. The accuracy thing is just for you to have fun, not to find cheaters or anything. Like I said, let you be happy with your own percentage.
