Practical Chess Notebooks 5: Castling Attacks
 The exercises in this notebook illustrate typical castling attacks in their final phase, usually with a combinatorial result. Small castling attacks were studied in Chapter 8 of the School of Chess and then in the extensive Chapter 7 of the School of Chess 2. Of course, the theme of the castling attack is extensively developed, in addition,
 In the three books of the Encyclopedia of Tactics (Tecnica da combinación de mate, Escola de Tática and O Ataque no xadrez), the latter two to be published soon by Editora Solis, the book is properly organized by theme, with numerous diagrams and exercises. The student should take into account that, when solving the exercises, he is not asked to decipher each and every move of the game (which, at times, are included until the end, for documentary purposes), but only those that, let's say, lead to a decisive advantage for one side (+ -, - +) or forced draws (=), when appropriate. There are exceptions (and, in this sense, the guidance of an instructor, or the reader's own common sense, is important), because if the first one or two moves produce this opinion, it is worth expecting the solver to provide additional concrete lines that enrich the solution. Chess is not a mathematical science and admits several interpretations.
 There is only one formula for progressing in chess: playing as many tournaments as possible, along with theoretical study and analysis of one's own games. The ideal complement to this formula, as many Grand Masters recommend, is for the player to develop and perfect his tactical and strategic ability by solving numerous exercises, specially selected for their usefulness. Like the ones we offer you here.
