FOREWORD
Several years ago Soviet theorists were set a task -to create for our classified
chess players a monograph on the concluding stage of the game - the
endgame. This work was to present the latest practical achievements, and to give
theoretical conclusions on all basic types of chess endings.
The preparation of such a work required a fair amount of time, and it became
clear that the material collected could not be contained within the bounds of
one volume. Therefore the decision was taken to issue three books, devoted to
different types of endings, connected by the general title 'Chess Endings'.
The work on 'Chess Endings' proceeded in two directions. For endings with a
small number of pawns the authors attempted to collect as much reference
material as possible.
For endings with a large number of pawns, the basic task set was to show the
most typical positions, and to attempt to give practical advice on the playing of
such endings.
With the exception of a few elementary positions, all the positions for which
no author is specifically mentioned have been compiled and analysed by the
author.
The term 'the stronger side' is often used in this book. To avoid misunder­
standings, we should explain that this refers to the side which has a material or
positional advantage. The book as a whole is intended for players of second
category rating or higher, but the contents of certain chapters may also prove
useful for less experienced readers.
In conclusion, we consider it our pleasant duty to express our thanks to all
who have helped in the preparation of this book.
All comments and criticisms should be sent to the address: 'Moscow, M.

2 BiJhop and Pawn v. Knight
J: Thus in this example White can­
not dislodge the black king and
promote his pawn.T he attempt to win
the knight is also unsuccessful, e.g. I
K-B5 K-Q.l 2 K-K4 K-Q.2 3 K-K5
K-Q.l! (J . .. K-KI ·' 4 K-K6! K-Ql 5
P--Q? and wins) 4 K-Q.4 K-Kl 5 K-B5
K-Q.2 etc.
Now let us turn to a systematic
study of positions where the weaker
side does not succeed in blockading
the pawn with his king. We will state in
advance that positions with a rook's 5: Both the weaker side's pieces are
pawn will be considered separately at taking part in the struggle with the
the end. We will first of all take cases pawn. Here the result depends on who
where the pawn has already reached it is to move. Black to move gives
the seventh rank. perpetual check: I ...N -Q.3+ 2 K-K7
N-Bl+ 3 K-KB (J K-K6 N-NJ) 3 ...
4 N-Q.3+ etc.
+ However, this result is determined
not so much by the position of the
black pieces, as by the poor position
of the white king. White to move im­
proves the position of his king and
wins: I K-K7 ! N-Q.l 2 B-K4 N-B2 3
B-B3 N-Q.l 4 B-Q.5 etc.
Moving position 5 one file to the
left, we obtain position 6.

4: The knight has to take the full
weight of the struggle with the pawn.
The king merely defends the
approaches to the knight. Black's
defensive problems are too much for
him to cope with.
White wins in the following way: I
B-K4 N-B2 2 B-B3 N-Q.l 3 B-Q.5
N-B2 ! 4 K-K6 ! N-Q.l+ 5 K-Q.6
K-N2 6 K-K7.
The winning method -restricting
the mobility of the weaker side's 6: This position is an exception,
knight, leading to a position of since restricting the mobility of the
zugzwang - is typical. black pieces leads only to stalemate.
