You're obsessed dude. Cheaters aren't playing bums like us often enough to notice. The ops reckoning ain't dead, but it's close enough.
Cheats are playing at all rating levels. Intermittent cheating, is quite common. They use their engines during small parts of the game. Often times this is enough for them to win. Sometimes not.
And when they "turn on" their engines, they (sometimes) start to taunt you in the chat box. It's all very entertaining. Except then, you typically lose.
I've been playing chess here for six years. I've played four opponents who were later banned for cheating.
If there are folks who use an engine for only a couple of moves a game, I'd never know the difference anyway. Why do you think there are many folks who do this? What's the point?
I see many who intentionally play worse moves than the best, that were obvious, to lower their t-stat scores that are used in cheat detection analysis. People here have some real misconceptions about what it is like to play against someone, who using engine assistance in various forms.
Of course people cheat here, but this gets a little too machiavellian. Why on earth would you combine cheating with intentional bad moves? Does this make sense to anyone? You play a flawless computer move, then balance it out with a blunder? What is the goal?
What the hell is an obvious best move anyway? Is that a forced move? If it's not, it's obvious to whom? Obviously, what's obvious to trysts isn't obvious to me.
Some people get a decisive advantage using an engine and then play the least highest scoring move according to analysis, so that the resulting mass stats from the games don't reveal anything fishy. This usually isn't discovered until the games are looked at individually and according to the deviation scores.
Some people think things are always so simple, until the are more closely scrutinized....
This discussion isn't on cheating... but really, why would people be cheating. We're not playing for money. In limited time controls, it is difficult. It is hard to use another computer program with chess.com. In long time controls, it is very possible, but you get back to that motivation factor again. Mostly, people are on here because they like to play the game, and think if they play more, they will get better, which sadly seems to be untrue.
