Don't make public accusations, if you suspect then report and leave it at that. Besides, he hung a piece in the opening which you didn't take, you hung your queen, he made 2 blunders in the game and finished with an accuracy of 77%. So on the balance of that evidence it sounds more like your grapes are sour than that your opponent was cheating.
[Public accusation deleted] is a cheater. Beware
I didn't say that I played a good game. He kept dis on eating then plays perfectly. Took several seconds to take my queen. Also if intermittently using an engine the accuracy will be low. Perfect to hide from moderators
Also look at what the engine suggests in the analysis. From move 7/ 8 onwards plays very very differently. This is a cheater. Using computer engine every now and again

Not really, it's pretty easy to find good moves when you are up a queen plus the top choice was not played every move. OK you have your opinion but regardless you should not accuse publicly in this fashion.

I'm posting to warn everyone not play this cheater. Clear to me using computer intermittently during the game to hide from moderators. Unfortunately I don't think chess.com is good enough or sofisticated 5o detect these cheaters. Keeps disconnecting every time the position is complicated then comes back with perfect moves. Multiple times
