The Ruy Lopez is one of most important openings and the Zaitsev line 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba6 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.h3 Bb7 10.d4 Re8 is one of most popular variations. This book is a complete guide to handling the black side of the Lopez, based principally around the Zaitsev Variation, upon which Anatoly Karpov relied during much of his career. This line leads to sharp play, often in open battles where Black gains active counterplay and challenges White to seize the initiative on the kingside. The authors analyse also other lines by White between the 4th and 9th moves. A sample from the book is available on publishers website gambitbooks.com
