The three-volume work is united by a common idea - tactics and combinations in chess. In fact, this is a turnkey textbook, it explains everything from scratch to an advanced level. The second volume is devoted to the basics of calculation techniques, such topics as the tactical "spectrum" of a position, concentration of attention, inclusion of imagination are considered, the "tree of variations" is interpreted in a new way, the practical component is emphasized - the economy of calculation. A separate chapter allows the reader to assess their ability to calculate variations and outline ways to eliminate weaknesses. Each chapter ends with a large number of carefully selected examples for independent solution. Unlike other similar publications, the author examines chess tactics as a single whole, in combination with strategy and elements of psychology.

Excellently selected examples, a clear logical structure and consistency in the presentation simplify the understanding of the material. For a wide range of chess fans.

The authors continue to study typical opening and middlegame positions. Royal Fortress No. 2 has pawns on squares f7, g6, h7 (or f2, g3, h2), and they are usually joined by another defender – bishop on g7 (g2). This formation is called fianchetto, it is found in many popular openings, such as the Catalan Opening, King's Indian Defense, Grunfeld Defense and a number of others.  The authors analyze in detail the techniques of attack, defense and counterattack. Most examples – from the creativity of modern chess players (for example, a separate chapter is dedicated to the strongest Russian grandmaster Ian Nepomniachtchi); they are complemented by parts that have become a classical heritage. The book contains about 300 positions for independent solution, so it is not only a textbook, but also a solid problem book. Grandmaster Konstantin Chernyshov, head of the Interregional Grandmaster School in Kostroma, and his daughter International Master Natalya Kareva – experienced coaches, whose students include grandmasters and masters, champions of Russia and Europe among juniors.  The book is addressed to young chess players and their mentors.

Den-Hertog, and "Chess Lessons". The first work is designed for beginners, the second for more experienced chess players. The book is a real chess tutorial in the true sense of the word.

International Master Tibor Karolyi and FIDE Master Tigran Gozalyan have prepared a major work (in two volumes) about the life and work of the 9th world chess champion Tigran Petrosyan (he held the title from 1963 to 1969).  Volume II (1963-1984) tells about Petrosyan's victory in the 1963 world title match over Mikhail Botvinnik, about the grandiose two-match confrontation with Boris Spassky in 1966 and 1969, about all his candidates' matches after losing the title – against Bobby Fischer, Viktor Korchnoi and other world-class opponents. All tournaments and matches of the second half of Petrosian's chess career are presented, up to his last performances in 1983. The authors subjected 175 complete games and fragments to an in-depth analysis (using modern computers). Not all of them have been deeply studied and commented on before, but even then the book provides a significantly improved analysis. Among Petrosyan’s opponents – world champions and contenders Kasparov, Karpov, Fischer, Spassky, Tal, Smyslov, Botvinnik, Korchnoi and Bronstein, as well as Timman, Larsen, Reshevsky, Belyavsky, Polugaevsky, Portisch, Romanishin and many others. Special attention is paid to his coaches – Alexey Suetin and Igor Zaitsev.
