The content of this book is a training program for players who plan to play an over-the-board tournament a few weeks from the time they start training with this book. This book, unlike other similar books in the field of improvement, does not have a central theme. In other words, we are not focused solely on openings, middlegames or endgames. Moreover, the book does not only concentrate on specific themes (calculation, positional decisions, or other strategic aspects), though many of these concepts are addressed throughout the book. Instead, this book offers a holistic view on how to approach every single position in it, regardless of the phase of the game or the nature of the position. We try to teach players how to identify types of decisions in various positions, while pointing at the trade-off between a hardcore calculation and a heuristics judgment.
