The Art of the Game of Chess is the first English translation of Fr. Ruy López’s 1561 book about chess, Libro de la invención liberal y arte del juego del ajedrez. López was a priest who served as King Philip II’s confessor and royal advisor. As a connoisseur of chess, King Philip II promoted the game in his court, and it did not take long for López to become known as Spain’s and one of Europe’s greatest chess players. López is widely acclaimed as one of the most influential chess thinkers of all time whose theories of chess are an integral part of how chess is played today. Academics, including historians, linguists, sociologists, and Hispanists, as well as non-academics, especially chess enthusiasts, will appreciate this translation, which opens with a Foreword by Andrew Soltis, who is a Grandmaster and a United States Chess Hall of Fame Inductee, and includes a critical introduction and more than 275 footnotes.
