Its author is FM Alessio De Santis, winner of a lot of Chess Tournaments. He has obtained three IM norms.
The book (270 pages) is written in italian language but it has algebraic notation. Price € 19,98 + shipping.
We really like this book because De Santis knows the matter having played 1.b3 many times.
A magnificent work, a labour of love!
