This is the first monograph in the English language on one of the most important opening chess strategies. Eric Schiller has carefully researched the Zaitsev Variation of thr Ruy Lopez, the most popular form of the so-called Spanish Inquisition. Although it only surged to popularity in 1976, it has become the dominant variation of the Spanish Game. All of the positions arising after 1 e4 e5 2 Nf3 Nc6 3 Bb5 a6 4 Ba4 Nf6 5 O-O Be7 6 Re1 b5 7 Bb3 d6 8 c3 O-O 9 h3 Bb7 10 d4 Re8 have been thoroughly researched, with references to over 240 games, more than half presented in their entirety. Particular attention has been paid to the Kasparov - Karpov encounters, and fresh new analysis of many critical positions is presented. Present World Champion Gary Kasparov, Former World Champions Anatoly Karpov, Boris Spassky, Mikhail Tal, Vassily Smyslov, Championship Candidates Belyavsky, Byrne, Geller, Hort, Hjartarson, Hubner, Portisch, Short, Sokolov, Timman, and Worls Class players DeFirmian, Ljubojevic, Psakhis, Romanishin and Van Der Wiel are just some of the players who include this variation in their repertoire, many on both the White and Black sides. Anyone who wants to see how the big boys experience the Spanish Inquisition will find plenty of interest in this us-to-date and well-organized volume.
