Libro en inglés “I realize that this book will not cover all open wounds, nevertheless my aim to write a manual about defense which can help us defenders enduring the hardest difficulties in practice, seems to be achieved. Personally speaking this book helped me as a defender to approach a worse position in a much more objective way, optimally use all of my defensive resources available, both psychologically and technically, to set – even under the most dire circumstances – pitfalls, while keeping my nerves under control.” ~ Jan Werle
