Practical Chess Notebook 11: The Problem Piece
 The issue of the problematic piece, which is only dealt with in manuals, is of fundamental importance because of its strategic and tactical impact on the game. "One badly placed piece and the entire position is bad", said Dr. Tarrasch in one of his definitive and radical statements. Without going to that extreme, in modern chess, where players are accustomed to detecting the slightest favorable or unfavorable nuances, the existence of a problematic piece can compromise or limit a player's entire position and the opponent can exploit this fact to his advantage, achieving victory. Chapter 5 of the work "Chess School 2" presents a detailed study of the different cases of problematic pieces. In this notebook, we will group the exercises into four chapters, with very interesting cases of pieces whose position on the board is negative. 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, 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.
