Why does people cheat on Chess?

huh? how can you tell that they're cheating? what is "theonspy"?

People cheat in chess primarily to gain an unfair advantage, often using computer engines or external help during games. Fire kirin

First to answer the question: some people cheat because they can't deal with losing, be it out of anxiety or a fragile ego, lust for elo to show off to others - there probably are several reasons but the root is an inability to cope with a loss in a meaningful way.

I'll have to add that "self deiagnosed" cheating of opponents is a pseudo science and the road down to paranoid general suspicion on anybody that beats you in a way you don't understand is a very quick one. People think their opponent is cheating way to often, they don't present any proof and yet they're convinced they're right - that doesn't seem sensible.

I'm not saying cheating isn't happening, I'm saying the number of unfunded accusations is too high.

Then if you don't know the code and performance of some anti cheating software then what does your opinion about it matter?

cause they suck, and are scared to admit it.
