Practical Chess Notebooks 6: Attacks on the King in the Center
 King in the center is a concept that has been established in the chess lexicon, but it is not very precise. In fact, when we talk about attacks on the king in the center, it is understood as being on or near its starting square. This square (or position) does not have much to do with the geometric center of the board, but rather with the center of the last (or first) row. It would be more logical to refer to this figure as a king without castle, or something similar. However, we respect the expression, as we consider it to be a commonly used term. The exercises in this notebook illustrate the topic studied in chapters 8 of the Chess School and 7 of the Chess School 2. When solving the exercises, the student should not try to decipher all the moves of the game (which are sometimes included until the end, for documentary purposes), but only those that lead to a decisive advantage for one side (+ -, - +), or to forced draws (=) when applicable. There are exceptions (and in this regard, the guidance of an instructor or the reader's own common sense are important), because if the first or second move produces this impression, it is to be expected that the solutionist will provide additional concrete lines that enrich the solution. Chess is not a mathematical science and admits of several interpretations. To progress in chess, there is only one formula: participate in as many tournaments as possible, together with theoretical study and analysis of the games themselves. The ideal complement to this formula is, as many Grandmasters recommend, for the player to develop and perfect his tactical and strategic capacity, by solving numerous exercises, specially selected for their usefulness. Like the ones we offer you here.
