It took some time to get my copy of this book:

Written by GM and worldchampion Slumstrup Nielsen, Steffen 1975 and (otb) GM Jacob Aagaard.

Endgame Labyrinths presents the reader with 1002 challenging studies selected and truncated, with their usefulness for the practical player in mind. 

At forwardchess.com Jacob gives an introduction of the contents of the book.

In the book with 424 pages 1002 nice endgame studies are presented.

Its starts with a foreword by well known Afek, Yochanan 1952.

Then it explains why training by solving endgame studies is useful to develop calculation skills and decision making skills.

Because the authors did extensive computer checking, the studies presented should all be sound.

The selected studies are realistic reflecting types of positions and decisions that you are likely face in "normal" chess games.

They explain the "Points System" used by solving tournaments.

With each study they present the difficulty is showed using up to 5 stars.

Then they explain how the quality of a study is valued by naming 8 conventions.

This of course can be found on this website but it is good that it is explained.

They mention and explain:

1. Traditionally endgame studies do not begin in “mid-action”
2. The first move of a study cannot be a capture
3. The king cannot be in check in the initial position
4. All pieces must move during the solution
5. Avoid exchanges
6. A natural starting position
7. White begins
8. The composer dictates the main line

Then there is a chapter with explaining Themes and Tactics which are used in the book.

A few of them I could add to Glossary || Terminology

With chapter 7 the real work begins with Pawn Endgames.

Chapters 8 to 17 are organized around material like "Knight Endgames", "Rook vs a Minor Piece" etc.

Chapters 18 to 26 are organized around themes and tactics like: Fortress, Active Defense.

Finally ending with Brain Crushes

and an Index of all Players and Composers in the book..

A very usefull book to enjoy solving endgame studies and developing endgame skills.

But also very important explaining where and why points are given in Solving contests.
