Hey guys!
I am tired all of the players who can't lose and writing notes to my account with " he is engine user, cheater etc." . I disabled the chat, because the players who play bad always writing something.
And no.. i am not a great player, I am ELO1200-1300. I am bored people harassing other people because they play better. That's why i will not buy premium to this site.
Also I played to a player who play realy bad (We had 7-8 games before with the result of 7W/2L for me) after 10-12 moves he is writing that i am engine user and he will report me, and he is turned on a chess engine and won... i am so tired of these kind of players. Please chess.com try to do something, because players who realy want to improve their game, will not play on this site.
Thank you.
