Please report cheaters!

I played a CORRESONDENCE game for a few days against someone that made 1 innacuracy, 0 mistakes and 0 blunders, ACL 16.

Is it suspicious or just someone too good for me?

Keep into consideration that I am not a good player by any means, so it must be easy to avoid mistakes against me.

What do you think? All my games and stats are open.

I agree that using an engine to cheat (a.k.a. "(C)heating") is a pretty egregious offense towards the game of chess in general. However, it is quite possible for a player to just be a very good player, and I would not want to see the next Bobby Fischer, Garry Kasparov, or Magnus Carlsen get kicked off the site under suspicion of cheating.

If you play a game poorly enough it's damn near impossible to tell if someone was using computer assistance. I mean, who needs Crafty or Stockfish to see a hung queen?

Here's a computer analysis from a game I played the other day. The names have been removed but the ratings remain. My opponent's accuracy was highly suspicious to me given that it was a 3+0 blitz game. Would you report this sort of game or not?

I used to cheat a lot in the past and I just want to say that it is entirely false that rating will take care of everything. For example, on the old chess.com I would cheat every game and barely get 2000 rating. That's I guess how rating takes care of cheats since all us 2000+ would cheat vs each other, but it didn't really suck for us, even today I'd like engine vs engine games, it just made it suck for the few real people that played there. BTW They have cleaned up the site quite a bit since then, I'm talking 2010 here.

My pride was to keep the rating around 1800-2000 on most sites (I had an honest 2000+ on several sites too) and the fun was to see if others would find the "only move" in some situations. IE: I was creating puzzles with my engine. However, when came tournament times (they were swiss format, not arenas like here) I would purposefully ruin the top place finish of a strong player and lose a "tight" game with the one I felt could beat him.

All that because some AJ Goldsby accused me of cheating publicly when I beat him fair. In fact, I didn't even know how to cheat until the accusations which prompted me to look into it.

@chess240 Yes, you totally should, hopefully admins can check the user's history to check if he is indeed cheating. From you show though, I would not be able to claim he cheated, but he probably didn't cheat only vs you if he is indeed an engine, so it would be an easy catch.

@QBall Magnus Carlsen played in the pro chess league (15 2 time control), hung a queen for a rook and his opponent didn't take it. Even the world champion cannot constantly play at an engine's level, even 2700+ GMs sometimes miss tactics. Don't worry about them getting kicked off by being too good, it won't happen, it will be obvious that they are human.

Stockfish plays at the 2500+ level, every single game, every single move (unless you have a non-retard cheating, then there might be a few non-engine moves here and there) and it becomes very obvious very fast when sometimes plays more than 90% engine moves or tablebase runs.

Magnus is 83% like an engine in classical chess. Imagine how low that gets in blitz.

"I used to cheat a lot in the past ..."
And with everything else you said, sorry tabarjack but if we ever get paired I'm aborting our game.

@CafeMorphy That's a bit of a closed-minded view. If @tabarjack cheated on some other site in the past, that does not necessarily mean (s)he is a cheater now. For all you know, starting over here could be part of "turning over a new leaf" and committing to play only honest chess here.

You are within your rights to refuse to play anyone, of course, just as I am free to say it appears you are doing so for all the wrong reasons (and it does).

I've been playing online for 20 years, been a mod on a site for many years and let me tell you, once you realise what scumbags cheaters are, and how they are ruining online chess, it's indeed very very hard to forgive.
But maybe I need to develop my Jesus side more...

I suggest pairing cheaters against each other preferably resp. pairing them against engines.
