As a standalone the book makes a well organised and researched impression.
I´m especially happy to see coverage of the lines
A) 1.e4 c5 2.Nf3 d6 3.Bb5+ Nc6 4.0-0 Bd7 5.Re1 Nf6 6.c3 a6 7.Bf1 and
B) 1.e4 c5 2.Nf3 e6 3.g3, while the option of
C) 1.e4 c5 2.Nf3 d6 3.Bb5+ Nd7 4.d4 Nf6 5.Nc3 (instead of Jones´ 5.0-0), retaining the possibility to castle long in some lines, also looks interesting.
Thanks to the tree structure and the index of variations the book is easy to work with.
However, there are also some things I find annoying, like the author stating the obvious, e.g. after black plays ...g6 in some position I have read countless
times something like "Black prepares the development of his bishop to g7."
Also I´m under the impression the book lacks somewhat in proper attribution of lines analysed in earliers works of other authors (Jones, Greet).
A strange example I have found:
Here Greet in "Experts on the Anti-Sicilian" wrote after black´s next move 12...Qxc6: "Black wants to retain the possibility of ...b5."
And this is what Kornev has to say: "Black preserves the possibility to play b7-b5."
I have found some cases where the analysis of other authors is used without giving credit.
There might be some other things to critize but overall I think the book is a good addition to Jones´ earlier work.
