I was just sent a review copy of Correspondence Senior International Master Jon Edwards' Sacking the Citadel: The History, Theory and Practice of the Classic Bishop Sacrifice, and it's unlike any book I'm familiar with. The question that comes to mind is the one GM Karsten Müller asks in his Foreword:
A whole book on the single motif Bxh7+? Is this really worth it and is enough relevant material, I hear you ask. I can assure you that there is. The theme is so deep and so rich that Jon Edwards has even decided to deal only with Greco's version of the classical Greek Gift sacrifice, Bxh7+.
The book is divided into three unequal parts. Part I, "History", consists of a 12-page chapter called "The Life and Times of Giaocchino Greco" (1600-1634), who Max Euwe called "the first great genius in the history of modern chess". Part II, "Theory", has four chapters. The first three summarize the important classificatory attempts by Edwin Voellmy, Eugene Znosko-Borovsky and Vladimir Vukovic, while the last, "Contemporary Theory", attempts to bring the taxonomy up to date. This brings us through page 92, and now comes the bulk of the book: Part III, "Practice". Chapter Six, "Games", offers 308(!) games dating from Greco-NN in 1610 to Brechin-Shaw, Edinburgh 2009. (The games are all deeply annotated from the point of the sacrifice through the point where the relevant complications have resolved.) The games are presented in chronological order, but if you're looking for various sub-themes there's help in the chapter on contemporary theory and in an index. Finally, the book concludes with 30 puzzle positions, a brief "Related Literature" chapter, a bibliography and several indexes.
Pace Müller, I'm still not sure anyone needs a 400-page book on the Greek Gift sacrifice, but all the same Sacking the Citadel is extremely well done! Edwards is clear and thorough, and even if one's interest in the topic isn't quite as intense as the author's, the book still works as a collection of well-annotated games. If the topic interests you, then this book will be your dream come true.
