I think that this work is outstanding for its comprehensiveness, lucidity and honesty, and I think that it'll be very useful for many players. It's quite admirable that Vigorito has taken the trouble to point out what's wrong with some of Black's likely alternatives to his recommendations, which ensures that these volumes will be useful for White's partisans as well as Black's.
I do, however,have a very specific observation about the coverage of the Makagonov with 7...Nh5 (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.h3 e5 7.d5 Nh5). After
8.Nh2 Qe8 9.Be2 Nf4 10.Bf3 f5 11.g3 Nxh3 12.Bg2 fxe4 13.Be3, Vigorito says "as Markos points out, Black is okay after 13...Na6! 14.Nxe4 Bf5 15.f3 h5!." This appears to be an untested recommendation; I have three games in my data base that reached 15.f3, none with 15...h5. And given that it is untested, this would be a place that I would look hard to find something for White. Obviously, White can redeploy his h2 knight to d2 with tempo (16.Nf1 Qd7 17.Nfd2), after which I wonder if Black is really all that O.K. with that funny-looking knight of his sitting there on h3.
It's interesting that Vigorito devotes a half page or so to 13.Nxe4, but only this little note to 13.Be3. Maybe this is one place where he wants to keep his secrets. Or is Black's O.K.-ness after 15...h5 really that obvious?
P.S. after 13.Be3 Na6 14.Nxe4, Black has a possible improvement in 14...Nf4!? as played in Macieja - Maze, Aix-les-Bain, 2011. Too late to make the edition, or judged not relevant?
P.P.S. It's worth noting that besides 7...Nh5, Vigorito covers both7...a5 or 7...Na6 in detail.
+1 regarding the initial praise. I have most relevant books published in later years on the KID and concerning comprehensiveness, usability and ratio between variations and explaining prose these 2 volumes come out on top. Other books are useful when the recommended variations does not fit in your own repertoire (I'm not all that enthusiastic about the Panno Saemish f ex) and as a comparison, but if I had to choose one reference work I'd pick this one.
As with all theory books, if you look deep enough in specific variations you'll find assesments which are wrong and recommendations that does not fit your style. A major strength to me is that you get a very good picture of current theory and thus have a good base to do your own research on.
