Two quotes:

"I found the chapters on the Samisch and Fianchetto lines the most interesting. Golubev advocates the Panno Nc6 line against the Samisch, and the classical Nbd7/e5 line versus the Fianchetto.  This is of course a matter of taste, but my experience is that players who play the Panno Samisch also play it against the Fianchetto.  So, I was quite intrigued by this slight "change of stance" by a leading KI player.  In any event, the material that the author presents in both variations should be more than enough to make the reader feel confident as well as comfortable when facing these lines."

"On the minus side he doesn't look at Taimanov's 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.Bd2 or at the Larsen line 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be3. Both of these lines are quite venomous if not known."
