Your description of this person's games does not sound like cheating. If a person makes an erroneous move and does not lose, that is not simply because they played better later in the game. It is because their opponent also made an erroneous move. As Tartakower put it, "The winner of the game is the person who makes the next-to-last mistake."
dude are you kidding me lol. he admitted to cheating to me in the chat. i checked his matches he plays at an insanely high accuracy often and then purposely loses games in a row to manipulate his rating. I already said in my original post that im not delusional it is a very very obvious cheater ive reviewed a lot of his games and he admitted it to me.
I believe it, the cheating problem grow and grows....
