Jakov Geller, born in Moscow in 1986, achieved the grandmaster title in 2011.

His new book focuses on a key element of tactics: forced mate. It contains 1500 positions rife with tactical resources; 1380 of them are presented as puzzles. The book is divided into 31 chapters, most of which are dedicated to a single tactical method, which is described in detail. This fundamental work systematizes the methods for delivering forced mate, which include sacrifices, pawn promotion, vacation, attraction, elimination, deflection, blocking, seizing the square, x-rays, pins, discovered checks, double checks, windmill and interference. The rest of the chapters are titled Combinations; they are used to consolidate the provided knowledge and test the acquired skills. They contain the theoretical basics of the combinations and cases studied, but to solve these puzzles the reader will also need to use techniques they studied in previous parts of the book, rather than in only the current chapter. Therefore, each new tactical method studied gradually increases the diversity of combinations used in the subsequent chapters. The puzzles in every chapter also gradually increase in difficulty. The last chapter makes the book useful even for top-level players, because it consists solely of difficult puzzles and can be used as a universal test to check forced mating skills.
