Bronznik, Valeri m.fl: Techniques of Positional Play (PB)
Opening preparation is useful, but understanding the middlegame is much more important. This book, an improved edition of a Russian classic, teaches amateur chess players 45 extremely effective skills in a crystal-clear manner.
Quite a few of the ideas presented here will surprise the reader, because they offer solutions for problems the club player is only subconsciously aware. How do you activate your rook pawn? How do you prevent your opponent from opening a file? How do you restrict the efficacy of your opponents pieces? Which rook belongs on the c-, d- or e-file? What is the best way to exchange a piece? How do you castle artificially?
In most cases the techniques are easy to understand and memorize. Bronznik and Terekhin do not burden the reader with deep analysis and only present those variations that are really necessary to get the point. There is a special training section at the end of the book where you can test your skills.
