The diverse set of tactical ideas involving a single queen in the finale will enable you to gain a deeper understanding of the queen’s resourcefulness

International Master Maxim Chetverik has written an in-depth study of one of the most popular choices by white in the Queen's Indian Defense - the main line with 4.g3, where white fianchettoes his bishop. This line is often seen at top-level chess. This book contains 181 full games in this line and several hundred fragments with detailed and original commentary by the author focused throughout on giving a balanced evaluation in what are complicated positions.

Tigran Gorgiev (1910-1976) was one of the Soviet Union’s best endgame study composers. In his lifetime he produced around 400 studies and wrote three books and 101 articles with chess compositions. The vast majority of his endgame studies are of a practical nature, meaning that the positions presented could have arisen in over-the-board play. This makes them particularly useful to study for practical players as well as study fans. Sergei Tkachenko, a member of the Ukrainian team that won the 5th World Chess Composition Tournament in 1997 and which came second in 2000, 2004, 2013, and 2017, has selected his 100 favorite Tigran Gorgiev studies, revising some of them and providing explanations suitable for less experienced solvers. There are no more than six moves in most solutions, so experienced chess players can analyze the positions directly from the diagrams.
