BOOK 1 - OPENING PROBLEMS
 Chess openings always introduce an element of intrigue and suspense. What will our opponent play? How can we take advantage of our position? What surprises and unpredictable moves await us at the end of each variation?
 In Chess School (1 and 2) attention is paid to openings, within the limited space available in general manuals. In Chess School 2 there are two chapters: the first (The Game in the Opening) and the ninth (The Repertoire of Openings), the latter giving us a glimpse of the theoretical panorama, with some new ideas and, above all, the design of a repertoire according to each player's individual style. Once the player has chosen a repertoire, his task will be to study the openings he has chosen, to study them in depth and to note the novelties that arise at each step. This certainly requires clarification. A theoretical novelty is the new move that high competition (or, as we said before, master practice) supports and ratifies. A novelty is just a new move, an experiment whose merits and demerits have yet to be confirmed by competitive practice.
 There is only one known formula for progress in chess: play as many games as possible, along with theoretical study and analysis of the games themselves. The ideal complement to this formula, as many great masters recommend, is for the player to develop and perfect his tactical and strategic skills by solving numerous exercises, specially selected for their usefulness. Like the ones we offer here.
