Note for Coaches, Parents,
Teachers, and Trainers
After working through the first books in this series, the student has learned about
the relative strength of the pieces, mastered typical methods in attack and defense, and
learned how to checkmate in one move. This book presents the student with more
difficult problems.
Delivering checkmate in two moves is essentially a three-stage process. The winning
side has to find an attacking plan which would allow "capturing" the enemy king in no
less than three moves. Moreover, the player must account for the best defense and find a
way to overcome it.
When a chessplayer is carrying out a two-move checkmate, the opponent often
has several ways to defend. However, checkmate follows each time. This is where the
student will make use of his or her one-move checkmating skills. In order to solve such
problems, the student needs to see the final mating structure; barring that, the puzzle
might pose some difficulties.
This fifth volume sets several goals: a) to review checkmating skills; b) to teach the
student to feel the harmony of the pieces; c) to teach how to overcome the best defense;
d) to get the student into the habit of thinking in terms of calculation.
The book is divided into two distinct parts. In the frrst part, the student checkmates
without sacrificing material, while in the second part the student needs to find a
combination. Usually, authors of tactical manuals classify their material by combinational
theme (i.e., combinations with the theme of distraction, or blocking). Unfortunately,
players don't get such "hints" during an actual game. That is why, in this book, the
problems are structured by what pieces the attacking side has (for instance, the attacker
checkmates with two rooks, two bishops, etc.).
Problems where the attacking side has not more than five pieces and pawns
comprise the largest part of this book. These problems teach key ideas applicable also
to problems with more chessmen. Solving problems with a limited number of attackers
should allow the student to find checkmate in a variety of situations.
Very often the first move is a check. This cuts down on the number of variations the
student has to consider. There are a few problems which do not begin with check. In this
case the first move creates a strong threat, which the defender is unable to parry, and
puts the defending side in a state of Zugzwang, when all moves only make the position
worse. The later problems are more difficult, yet more beautiful. Learning to solve such
problems will advance the student's appreciation of the harmony of the pieces, and will
aid in mastering the deeper secrets of the game.

  • 7. Note for Coaches, Parents, Teachers, and Trainers After working through the first books in this series, the student has learned about the relative strength of the pieces, mastered typical methods in attack and defense, and learned how to checkmate in one move. This book presents the student with more difficult problems. Delivering checkmate in two moves is essentially a three-stage process. The winning side has to find an attacking plan which would allow "capturing" the enemy king in no less than three moves. Moreover, the player must account for the best defense and find a way to overcome it. When a chessplayer is carrying out a two-move checkmate, the opponent often has several ways to defend. However, checkmate follows each time. This is where the student will make use of his or her one-move checkmating skills. In order to solve such problems, the student needs to see the final mating structure; barring that, the puzzle might pose some difficulties. This fifth volume sets several goals: a) to review checkmating skills; b) to teach the student to feel the harmony of the pieces; c) to teach how to overcome the best defense; d) to get the student into the habit of thinking in terms of calculation. The book is divided into two distinct parts. In the frrst part, the student checkmates without sacrificing material, while in the second part the student needs to find a combination. Usually, authors of tactical manuals classify their material by combinational theme (i.e., combinations with the theme of distraction, or blocking). Unfortunately, players don't get such "hints" during an actual game. That is why, in this book, the problems are structured by what pieces the attacking side has (for instance, the attacker checkmates with two rooks, two bishops, etc.). Problems where the attacking side has not more than five pieces and pawns comprise the largest part of this book. These problems teach key ideas applicable also to problems with more chessmen. Solving problems with a limited number of attackers should allow the student to find checkmate in a variety of situations. Very often the first move is a check. This cuts down on the number of variations the student has to consider. There are a few problems which do not begin with check. In this case the first move creates a strong threat, which the defender is unable to parry, and puts the defending side in a state of Zugzwang, when all moves only make the position worse. The later problems are more difficult, yet more beautiful. Learning to solve such problems will advance the student's appreciation of the harmony of the pieces, and will aid in mastering the deeper secrets of the game. 5
