About cheaters.

Everyone must have come across a cheater at least once in their lifetime if you have played at Chess.com for long time. The thing is there are OBVIOUS ones and sneaky people. By means of obvious would be combination of "consistently slow", "Abnormally high accuracy", "Outstanding win rate", "New account". Sneaky people on the other hand, they are pretty smart. Whenever they get stuck on "End of Opening" to "beginning of midgame", they use stockfish moves to get extra advantage. They play on rapid, never on blitz and bullet, sometimes you can spot them they have more than 500 ELO difference. Ex. Rapid 1900 Blitz 1400 Bullet 700. Of course some are slow thinkers but there are incomprehensible feelings I get when I lose to cheaters compared to normal players. The way these annoying cheaters get away with ban is 1. to use stockfish only when critical moment, acting like thinking for long time and making good moves. 2. When winning many times in a row, losing few games on purpose to get out of Win-streak pool. 3. Playing with their own skills whenever they have advantage. I'm 2000 on Bullet and 1900 on Blitz. I am not random noob who is just yapping out on forum. Also with this subject, I feel like everyone faces similar problem. These sneaky cheaters have almost identical patterns. 1. Very quick opening (probably memorized to play 2 or 3 same openings everytime), 2. Normal defensive moves not attacking the opponent too quickly, 3. High win-streak + High lose streak. (Win 6 lose 1 Win 7) and then (Lose 8 win 1 lose 5) to match 50%ish win rate. 4. Very weird fluctuation of ELO over time. Usually people have growing ELO or small dropping, cheaters have high up and down. 5. Terrible end game compared to IM or GM level or mid-game. Especially when they have 2 or 1 min, they move suddenly quickly and can't even mate fast with queen and rook. (1600+ and can't mate with queen and rook over only king?) I feel like Chess.com is putting a lot of effort on catching OBVIOUS cheaters, but not paying too much attention on sneaky ones, I mean who could catch all of them? I just wish there's an trained AI to catch all of them with added systemetic pattern based on what I have mentioned above. Sneaky cheaters are definitely weird when compared to normal players. I hope they are punished by IP ban or sth.
