I only play Rapid against players around 1900 but games always seem pretty fair. I most certainly don't cheat but I very often get an accuracy in the high 90%.
I have occasionally had points back from an account that has been banned but to be honest, I am not unduly worried.
I only play for fun and don't worry too much about my rating. If players feel the need to cheat it is up to them but that feels like paying for a puzzle book and filling it in from the answers in the back - totally pointless.
I do think that over 1800 where most players are generally premium members, opponents are generally honest - at the end of the day, they will have to live to their grades OTB when things get back to normal.
Fischer said it would be days like this. But we call him crazy😀😀
