basic chess cheating explained and basic chess cheating example chapters.
If you haven't scanned those chapters yet this video might not make very much sense. The only audio during this video is an annoying poor quality song. There's no instruction or explanation. I suggest watching this without sound.
This video is demonstrating the Rybka computer chess engine, which is basically a chess program that's won several computer chess tournaments. If you're interested you can read more about Rybka at the wikipedia page about it - link here. I just used this Rybka video as an example. You don't need to learn about the Rybka to understand how to cheat at chess.
