basically, this is a definition of the rules and a (very) limited definition of some (very) fundamental go vocabulary. it contains nothing of value about how to play. at all. it's a decent introduction chapter to a larger book and that's it. when I reached the end I was very surprised that that was it. also, lots of spelling/grammatical errors. basically this is like a B- high school freshman essay on go for some writing class. maybe slightly longer, but not by much. I totally want my money back. even just 3bucks seems like a total ripoff. I just bought "go: a complete introduction to the game" for 5$ and the difference is astounding/astronomical. this is nothing short of a naked money grab.
