E-book Attack with Black

Gambit Publications issued the Kindle version of my "Attack with Black". Though, mostly it copies the paper book, it has one superimportant improvement. Those of you, who didn't know what to do against 12.a4 in the King Walk Variation, can find a revolutionary idea in this e-book! Hurry up to play it first in the real game!
