The book focuses on colour-complex strategies, essentially the control and use of white or black squares. The author has devoted a long time to this subject and considers understanding colour-complex strategies to be one of the key differences between strong and weak players. This topic is covered in over 100 annotated examples in several chapters such as Blockade, Opposite-Coloured Bishops, Exchange Sacrifice, Avoiding Weak Squares, and others, as shown in the table of contents in the second figure. Each chapter contains detailed explanations, and the last chapter contains tests. GM Axel Smith works as a coach, and most of his books have become bestsellers, including The Woodpecker Method, Pump Up Your Rating, and Street Smart Chess.
