Fairly interesting article about suspicions of cheating

The author's too secretive about his metrics for me to give them too much weight, but the general flow of the article (and the links from it) is very interesting.

The guy means that, if someone wins the sweepstakes on a chance of 10 million against 1, he is statistically PROVEN to have cheated? Isn't it possible to get the right move by analyzing the position? My FIDE rating is now 1914, and I managed once at a local championship to play the first 25 moves of an Evans Gambit exactly like a Russian grandmaster played it decades ago. (I won the game, playing white, and can post it here if you are interested...)

of course it is based on probabilit. You can never be 100% that someone is cheating on the internet since they might just play random moves that happen to match some engine.

Interesting read.
