Paperback will follow in a week or so.
It took 8 months to write.
Definitely the best chess book out there.
Chernev's "Logical Chess" should pale next to it.
Much more instructive, and much more entertaining.
There might be some grammar mistakes here and there, some intentional, but overall the book rules.
3 times better than "The Secret of Chess", especially the later sections, which the preview excludes.
If you call a "scam" spending 8 full months on it, 240 days X 7 daily hours, = 1700 hours of hard hard work, using Stockfish as well as the knowledge obtained during a decade of analytical work, that fully OK by me.
Here is the last game I played as black trying to improve my Hippo defence... I put a lot of efforts in trying to explain my choices, I hope to get some insights
Thanks, Davide.
