The books says 70's, but have a nice game's selection, from different decades, Kasparov knew the key games to explain the develoment of the opening.
Kasparov doesn't give, infinite variation, (like Kasparov used to) he argued the approach at that time, and how new ideas appear, this book in my personal opinion has better redatation from the Great Predecessor's collection, just for the approach.
This book was publish after Prdecessor's colectiion, but is not a sequel, this book focus to the opening, Predecessor focus on players and owesome games.
How does the book work?
The book have been divided in 24 chapter, each chapter approach to one opening. Kasparov marked the approach of the game and opening theory in particular variations, and how the process continues that overturned traditional impression.
All games as seen through the explication of leading player who were at the forefront of the develoment of chess theory during modern era.
My experience with the book?
I just use this for any advise, improve my insigth and help me a lot to understand opening, (acourding to the approach) and i can memorize lines easily. Just in my opening repertoire.
My recomendation?
Any kasparov's book, is a big deal but this book are oriented for opening lover or to improve a repertoire. This book will help any player but beginer player do not expect better result in games, for early result first must study tactic or positional games.
Great book, nice redation, for any chess player. I enjoy this book a lot and help me a lot to improve my repertoire.
Thanks, i hope this rewien help you a little.
