The book is controversial, several strong players love it. I tried to read it several times. Somehow I did not like his humor, although some of his analogies are really great, like the one where he compared the exchange of a figure which moved several times with an undeveloped figure to pigs: if you had to feed a pig during months, if this pig would die this would be much worst than a young pig. A lot of analogies are related to war, what is not a surprise. My face becomes (•◡•) when I have a look at this book. Really liked it.
