Looking at your opponent's games, I would say that he is most likely cheating.
Chess Cheater

Hi guys,
I have just played a game against an opponent ([removed -- MS]) and they seem to be playing very suspiciously. How do I make sure if he is cheating or not?
Thanks
he is definitely cheating I just was watching his game his opp traded rooks and it took him a few seconds to kill it meaning he was updating the analysis to get best move so yes he cheating

@ShikshaWithPraveen I am sorry I didn't know the policy, but I am just asking how to identify cheaters and if the opponent was suspicious or not.

Hey guys. I am playing a daily game against a player who is beginning to feel very suspicious. His rating on rapid is around 300, his daily 1000, but he's been winning all his daily games and all with 95+ accuracy. My rating is around 1800 on all time controls and if you check the game I have a feeling he is somehow going to put me in zugzwang. I haven't played a daily game harder than this one and certainly never played against a 300 rapid rated player who is this good. Can you check the game and if you think he is cheating report him ? I'm 99% certain he is cheating. I've played a lot of chess games in my life and 300 rapid playing 95+ accuracy on every game is just ludicrous. Here's the still going daily game ([removed -- MS])
Thanks

I wish Chess.com would tell us how the people are cheating, this is the primary reason I won’t buy a subscription is because I get cheated everyday
The reason chess.com banns forums talking about cheating is cause complaining does nothing to help why don't you try to create a new system for chess.com instead or move to lichess if you think this website is so overrun
