I have been using the chess.com app for over a year and played approx 2000 games on it. Chess.com is generally a nice app to start playing chess with (Elo 0-900).What i experienced after 900 is that random players start playing “surprisingly” well once they are about too loose the game. Quite often combined with a suddenly very fast playing style and essentially either winning by time or by checkmate. In timed offline games I play with an Elo between 1200-1400 but not on chess.com.There is certainly too much cheating / engine playing going on. When making chess.com aware of the problem, you do not receive any concrete answer but the forums and reviews indicate chess.com has a serious issue with cheaters.The other thing i disliked is the way chess.com automatically mutes your ability to chat with players. They call it an “artificial intelligence” but in truth it is a pretty ordinary word detector without any ability to understand the context! Calling this function an AI gives you a feeling how the people behind the app think and operate.If the app spots for example the word “idiot” they automatically mute your account between 1 to 7 days, despite the fact you wrote “i m such an idiot :)”. They then refer to their community guidelines..When you address this with their support, they frequently apologize about their “artificial intelligence” but make no effort in changing something. Some real intelligence would be needed!I also do not see the issue with fun or arousing talk. The chess.com bot does by also muting your chat function.Although I purchased the premium version of the app and have addressed the topic several times, chess.com does not react. Neither on the chat muting nor the cheating part. Being a premium user but being served and sanctioned by a bot which is working incorrectly is annoying over time.For everyone who plays better then Elo 900 (or has the ambition to get to this level) and also likes to communicate without immediate disciplinary actions, I would strongly discourage selecting chess.com and purchasing the premium version. After 1 year of premium subscription I will be leaving the app.PS: Also the automatic chess.com apology reply will not change my decision.
