Coming back to the actual book.
Overall this is one of the best repertoire books I have ever seen. Of course the choice of lines can always be argued with, but it seems to fit together nicely.
One exception is perhaps the line against the Ponziani
1.e4 e5 2.Nf3 Nc6 3.c3 Nf6 4.d4 Nxe4 5.d5 Bc5!? where Black is supposed to sacrifice two (!) pieces - perhaps a bit unpractical against a rare opening like this.
A few minor lines that I have found missing:
A)
1.e4 e5 2.Nf3 Nc6 3.Be2 - this has been played successfully by Jobava with the intention to reach a reversed Philidor after
3...Nf6 4.d3; something I haven´t seen mentioned anywhere in the book and which can also be reached via the Ponziani (see above) if White plays 4.d3 instead of 4.d4.
B) If the Portuguese
(2.Bb5) and the Nakamura
(2.Qh5) are covered, the Alapin
(2.Ne2) certainly deserves a mention too.
C) In the Four Knights after
2.Nf3 Nc6 3.Nc3 Nf6 the move
4.a3 is covered but in the Vienna after
2.Nc3 Nf6 3.a3 is not. This may have some importance because now
3...d5 4.exd5 Nxd5 allows
5.Qh5!? so Black should probably prefer
3...Nc6 followed by ...d5.
D) King´s Gambit:
2.f4 exf4 3.Nf3 Nf6 4.e5 Nh5. Now I haven´t seen any coverage of the third most popular move
5.Qe2 in the books by Shaw, Lokander and Ntirlis. It was once used by Keres in a game he lost against Alekhine so I certainly do not claim this to be good for White, but the idea of g2-g4 may not be so easy to deal with otb. At least practical result have been okay for White.
