Finally the book has been published! 

Currently you can find it on the New In Chess Website at this link or in ebook format see this link. 
At last here you can read a preview of it.
A great tool to minimize opening study and to create a sound and rock solid opening repertoire.
It's exactly what the non master tournament player needs!

BRAVI Welling & Giddins!
