El ajedrez is not a parallel universe nor is it enclosed in a hubbub. The XX siglo is gone, never to return. But its great events on the scaled table deserve to be rescued and valued, as it has been, at the same time, the worst and best of all times. The ajedrez is one of the most beautiful manifestations of the game that has given us life and is inscribed in what happened in its history. The book is not just a report, it is also a homage to the interpreters and protagonists of these hechos: them chess players, whose main seekers of chess gold and table magicians arlequinado has left an imborrable hue in the history of the king of games throughout the twentieth century. Not everyone is a hero. As in life, there are also second-row players and antiheroes, some of whom have left us with stellar and memorable creations. This is the world and this is human nature in its complexity and dialectical interaction.
