Cheating, except when done by an extremely strong player to begin with, tends to be utterly trivial to detect. For one reason among many more, a normal cheater will not really understand how difficult or easy some moves are and will tend to play a super-human move, requiring an exceptional depth of calculation, at the same pace which he plays a trivial recapture. Cheating in chess is maybe something closer to steroids in athletics. If you take an average Joe and gear him up with all the steroids in the world, he's not suddenly going to just hulk out and become a world class athlete, contrary to what many think. But if you take a world class athlete and gear him up, he is going to be able to use that gain a substantial and unfair advantage over his clean peers.
