The Modernized Ruy Lopez: A Complete Repertoire for White: Volume 1 by Darius Swiercz is one of the best opening books this reviewer has ever seen.The Polish-American Grandmaster, currently rated in the top 100 in the world at classical, rapid and blitz chess, has the reputation as a top-rate theoretician and his first book does nothing to dispel this. This massive work covers the following lines of the Ruy Lopez, primarily concentrating on non 3a6 lines:What comes through in this book is the authors objectivity. Some of the lesser lines are known to be better for White and Swiercz, who successfully played first board for the United States in the 2019 World Team Championship, provides practical solutions (for example 4.d3 instead of 4.Nc3 in the Schliemann). On the other hand the Berlin (3Nf6) and the Open Ruy (3a6 4.Ba4 Nf6 5.0-0 Nxe4 6.d4 b5 7.Bb3 d5) have excellent reputations, and along with a few lines in the Sicilian (the Najdorf and Sveshnikov come immediately to mind) are among Blacks very best answers to 1.e4. Here one cannot speak of a clear path to a White advantage and Swiercz does not pretend to, but he does offer challenging lines with new ideas and analysis. He also offers two lines against both the Berlin and Open Ruy, letting the reader choose depending on their tournament situation.A book like this undoubtedly has to have a lot of theory, and The Modernized Ruy Lopez does, but Swiercz does provide prose to guide the reader when needed. More importantly he provides the judgement of a world class grandmaster. Everyone can turn on their computer and check the computer evaluation but to actually understand the assessment is something altogether different and that is what you are getting with this book. The Modernized Ruy Lopezis must reading for a wide number of chess players. Everyone who plays the Ruy needs this book and those who defend it with non3a6 systems and the Open variation would be well advised to buy a copy. Opening books (especially now) have always had a short shelf life, but I expect Swierczs book to be the standard for some time. Highly Recommended - IM JOHN DONALDSON JANUARY 2021.
