Sacrificiul de la mutarea 6.d5 a determinat o revolutie in linia 4...Na6 din Indiana Damei, in ultimii ani.
Marele Maestru ungur Imre Hera si Maestrul FIDE turc Ufuk Tuncer au analizat in profunzime aceasta linie. Ei au oferit un punct de vedere foarte clar asupra istoriei liniei din deschiderea prezentata si au investigat toate raspunsurile negrului, in capitole separate.
Variantele spectaculoase sunt insotite de comentarii atractive.

Iata cateva comentarii in engleza:
Alexey Shirov: The book shows why the line is so attractive for White: fascinating chess, great complexity, chances to create fantastic attacking possibilities. This is exactly what we love chess for.

Dennis Monokroussos, The Chess Mind: "One reason this is an important line is that once Black has committed to a Queen's Indian, there aren't too many reasonable ways for him to avoid this gambit (..) [The authors'] work is thorough, accurate and creative. It's a very good book."

CHESS Magazine: "Plenty of dangerous new ideas."

Carsten Hansen, ChessCafe: "There is a massive amount of original analysis, fresh ideas, countless suggestions, and many novelties that overturn current evaluations."

Uwe Bekemann, German Correspondence Chess Federation: "It is clear that the authors have done their utmost to make the variations transparent and understandable (..) They came up with quite a few novelties."

Marshtower Chess Reviews: "Opened my eyes to a dynamic way of injecting life into one of the most solid of all defences to 1.d4. Even the World Champion, Magnus Carlsen, has played this way!"

Klaus Kreuzer, Rochade Europa Magazine: "Working with this extraordinary book is made easy because every section has an the introductions as well as a summary."

Elburg Chess Reviews: "This pawn sacrifice has been tremendously popular among top GMs ever since Vallejo Pons beat Macieja at the 2006 Turin Olympiad (..) This book shows us, as no other, the development of modern chess."

B.H.Wilders, Nederlands Dagnblad: "The avarage club player is able to fully understand everything and learn a lot from this book."

John D.Warth, Chess Club of Southern Indiana: "Hera and Tuncer excel at explaining complex plans in concise and unexpected ways (..) The book is thoughtful, mature and in-depth, yet straightforward enough to avoid confusion (..) Abundant diagrams adequately illustrate positions under discussion."
