i guess this is like a taboo subject around here. i once reported a person and measures were taken but it depends. sometime a long period of time is needed to catch a cheater.
Now PGN can be useful for you too: when you suspect someone of cheating take the file and put in a chess engine and compare the person's moves with the engine moves. if you have many similarities then use the file as a proof when you report the cheater.
Have fun!
I don't think this should be enabled until the game is over. I think this would greatly cut down on cheating.
Does anyone have an opinion on this topic? What's Chess.com's stance on this?
Thanks for your time.
