Club players love to study openings as so much material is available. However, it has often been shown that results do not match the amount of study invested, as in practice it is much harder to navigate your way around an opening when the opponent deviates from theory. 

This book, the third in its series, provides an overview of the positions and corresponding plans arising from the Sicilian Structures and in this first part the Najdorf & Scheveningen. The method is based on the column Understanding Before Moving in the chess magazine of the Royal Dutch Chess Federation; readers who follow it may hope to significantly increase their skill.
