Some of the problems in it may seem absurdly simple to experienced chessplayers or coaches. But that isn’t the case – the simplicity of our problems is superficial. If the required attention hasn’t been paid in the past to the development of these kinds of simple problems, that highlights the fact that there are still many blank spots in the matter of how to begin teaching the game of chess. This has to do with the fact that, in every country in the world, these problem books are written by strong practical players, for whom certain subjects seem too simple to be worth any attention at all. Such authors don’t take into account the fact that the earliest stage of instruction deserves closer attention. As a result, in previously published problem collections, a large stratum of useful chess exercises has remained unrevealed. The main goal of our series of problem books is to correct this omission. In order for the beginning chessplayer to learn to play chess well later on, the coach should first help him or her to establish a solid foundation. To this end, beginning players should first get the feel of the possibilities of each piece separately, and also familiarize themselves with the comparative strengths of the pieces. Our series of thematic exercises with a small number of pieces on the board serves this purpose. Problem books are written by strong practical players for whom certain subjects seem too simple, leaving many useful chess exercises unrevealed… At the same time problems from the so-called “pre-checkmate” period play a very important role in the initial stage of instruction. Very often there aren’t even kings in these diagrams, such that in order to win you simply have to eliminate or immobilize all your opponent’s pawns or pieces (as in checkers – play for a wipeout). The point of these exercises isn’t to deliver mate, but to acquire various chess skills, to master the simplest methods of attacking and defending. The purpose is to teach the student to see the chess board, to find hidden threats and connections between different pieces, and to understand how to coordinate the pieces to achieve one goal or another. By using our problem book, in the course of initial study beginning chessplayers can: 1) familiarize themselves with the possibilities and comparative strengths of each piece; 2) learn to attack one piece with another piece; 3) learn how to restrict the mobil5 ity of their opponents’ pieces; 4) learn to see guarded and unguarded pieces on the board; 5) learn to deliver double attacks; 6) learn to find defensive moves; 7) learn to use pins for attack and defense; 8) learn to choose the best capture from several possibilities; 9) master the typical methods of fighting with the various pieces against pawns; 10) learn to see opportunities to announce check in any position; and 11) completely master the rules of the game. In general, in order to achieve success in chess three stages of instruction need to be covered thoroughly: 1) the “pre-checkmate” stage – here, students should develop a feel for the “pre-checkmate” harmony of the pieces in both attack and defense; 2) the stage of giving mate in one – here students should get a feel for the harmony of the pieces when checkmating; 3) the checkmate stage – here students should get a feel for the harmony of the pieces when using a mate threat. Having said that, the younger the student, the longer the first two stages should last. This first problem book allows us to work through the first (“pre-checkmate”) stage, while the second and third books focus on working through the second stage (giving mate in one). Subsequent collections will help students and coaches to work through the third (mating) stage. 6 The Rook Capturing White to move: Can White take Black’s rook? w________w� °wdwdwdwd]� ‡dwdwdwdw]� flwdwdwdwd]� fidwdR4wdw]� ›wdwdwdwd]� ‹dwdwdwdw]� ¤wdwdwdwd]� ⁄dwdwdwdw]� w¡™£¢∞§¶•w� w________w °rdwdwdwd] ‡dwdwdwdw] flwdwdwdwd] fidwdwdwdw] ›wdwdwdwd] ‹dwdwdwdw] ¤wdwdwdwd] ⁄$wdwdwdw] w¡™£¢∞§¶•w 1 2 w________w� °wdwdwdwd]� ‡dwdwdwdw]� flwdwdwdwd]� fidwdwdwdw]� ›wdwdwdwd]� ‹dwdwdwdw]� ¤wdwdwdwd]� ⁄$wdwdw4w]� w¡™£¢∞§¶•w� w________w °w4wdwdwd] ‡dwdwdwdw] flwdwdwdwd] fidwdwdwdw] ›wdwdwdwd] ‹dwdwdwdw] ¤wdwdwdwd] ⁄$wdwdwdw] w¡™£¢∞§¶•w� 3 4 w________w� °wdwdwdwd]� ‡dwdwdwdw]� flwdwdwdwd]� fidwdwdwdw]� ›wdwdwdwd]� ‹dwdwdRdw]� ¤wdwdwdrd]� ⁄dwdwdwdR]� w¡™£¢∞§¶•w� w________w °wdwdwdRd] ‡dwdwdwdw] flwdwdwdwd] fidwdwdwdw] ›wdwdwdwd] ‹dwdwdwdw] ¤wdwdwdw4] ⁄dRdwdwdw] w¡™£¢∞§¶•w� 5 6 7 The Rook Pieces under attack Black to move: Take one of the white rooks. w________w� °wdwdwdwd]� ‡dwdwdwdw]� flwdw$wdwd]� fidwdw4wdw]� ›wdwdwdwd]� ‹dwdwdwdw]� ¤wdwdwdwd]� ⁄dwdw$wdw]� w¡™£¢∞§¶•w� w________w °rdwdwdRd] ‡dwdwdwdw] flwdwdwdwd] fidwdwdwdw] ›wdwdwdwd] ‹dwdwdwdw] ¤wdwdwdwd] ⁄dRdwdwdw] w¡™£¢∞§¶•w 7 8 w________w� °wdwdwdwd]� ‡dwdwdwdw]� flwdwdw$wd]� fidwdrdwdw]� ›wdwdrdwd]� ‹dwdRdwdw]� ¤wdwdwdwd]� ⁄dwdwdwdw]� w¡™£¢∞§¶•w� w________w °wdwdwdw4] ‡$wdwdrdw] flwdwdwdwd] fidwdwdwdw] ›wdwdwdwd] ‹dwdwdwdw] ¤wdwdwdwd] ⁄dwdwdw$w] w¡™£¢∞§¶•w 9 10 w________w� °wdwdwdw4]� ‡$wdwdwdw]� flwdwdwdwd]� fidwdwdwdw]� ›wdwdwdwd]� ‹dwdwdwdw]� ¤wdwdw$wd]� ⁄4wdwdwdw]� w¡™£¢∞§¶•w� w________w °wdRdwdwd] ‡dwdwdwdw] flwdwdwdwd] fi$wdwdw4w] ›wdwdwdwd] ‹drdwdwdw] ¤wdwdwdwd] ⁄dwdwdwdw] w¡™£¢∞§¶•w 11 12 8 The Rook To take or not to take?

But in the mass of chess literature little attention is usually paid to this extremely important stage of learning – problems where you give checkmate in just one move. Books that do include exercises on this theme have three faults: a) the positions aren’t classified; b) in the descriptions they tell you which piece will deliver mate, a circumstance which doesn’t correspond to the reality of a chess game; and c) there are less than 300 problems, which isn’t enough to acquire the skill of checkmating. Our collection doesn’t have those deficiencies. It contains 540 preciselystructured three-, four-, and five-piece positions that cover the typical mating setups for that particular number of pieces. There is also a practice section in the book (54 five-piece positions) and a section of entertaining puzzles (24 positions). After solving all 618 problems, the beginning chessplayer will master the typical mating patterns and gain a solid basis for further improvement. 5 Positions with Three Pieces King + rook vs. king

By solving the problems in the second collection, students acquired their first skills at checkmating the king, and learned to quickly give mate in one in simple positional setups. With the problems in the third collection, we aim to: 1) help students to see patterns in multi-piece positions in the opening and the middlegame; 2) teach students to use important tactical tools such as pins, discovered checks, and double checks to deliver mate; 3) familiarize them with the typical mating scenarios that arise no later than the 16th move of the game in various chess openings – primarily in those that beginners play at first (mainly the open and half-open games); 4) teach them to develop a feel for the smallest changes in the position of the pieces (to this end, we offer pairs of middlegame and endgame situations in which a slight difference in the initial position leads to different mechanisms for achieving mate); and 5) provide practice in giving mate in sixand seven-piece pawn, minor-piece and major-piece endings. Mate-in-one problems are still an underestimated theme in the training of novice chessplayers. The inability to quickly find an opportunity to give mate in one in any position has a negative effect on a player’s development. The majority of modern games end with both players short on time (in time trouble), and in those conditions the one whose skill at giving mate in one has become automatic enjoys a serious advantage. But not knowing just one of the typical mating setups, or being unable to see it in a complicated piece arrangement, often leads to defeat even for the experienced player. 5 Mate in One in the Opening Approaching the Opening Two Pieces Against a Whole Army White to move: Black has all of his troops on the board, and aside from the king, White has just one piece.

Even though there are many books on endgames, those books often disregard the simplest endings. This book has been written to cure this deficiency. The present volume is dedicated to the most important three- and four-piece endgames. In the majority of the problems the first move is relatively easy to find. Positions where the white pieces fight against the black ones comprise the biggest part of this book. Such positions teach the student to keep an eye out for checkmate, stalemate, and a variety of other tactics. Other goals for this book include the following: • enabling the student to learn the skills needed to play elementary endgames; • revisiting the skills of attack and defense learned from previous Chess Camp volumes; • gaining an understanding of the coordination between pieces; and • discovering the hidden potential of the pieces in attack and defense. Many authors underestimate the importance of solving elementary problems for the development of young chessplayers. That is why most of the problems the student will encounter are original and were created specifically for this book. 5 Endgames with Three Pieces King + rook vs. king Black to 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 Checkmate In Two without a Sacrifice King+ piece vs. king King+ rook White to move. 3 5 7 King+ rook Black to move. 7 8 9 8 King+ queen White to move. 13 9 King+ pawn Black to move. 19 23 10 King+ piece vs. various pieces King+ rook White to move. 25 11 King+ bishop Black to move. 32 31 33 12 King+ queen White to move. 37 38 39 13 King+ knight Black to move. 14 King+ pawn White to move. 50 53 15 King+ two pieces vs. various pieces King+ two rooks White to move. 55 57 59 16 King+ two rooks Black to move. 17 King+ two bishops White to move. 18 King+ two bishops Black to move. 73 19 King+ two knights White to move. 79 20 King+ two pawns Black to move. 85 89 21 King+ two different pieces King+ rook+ bishop White to move. 91 92 93 22 King+ rook+ queen Black to move. 97 98 99 23 King+ rook+ knight White to move. 103 a b c d e 106 24 f g h King+ rook+ pawn Black to move. 109 25 King+ bishop+ queen White to move. 26 King+ bishop+ knight Black to move. 27 King+ bishop + pawn White to move. 129 28 King+ queen+ knight Black to move. 133 135 137 29 King+ queen+ pawn White to move. 139 30 King+ knight+ pawn Black to move. 31 Victory in the Opening Open Games White to move. a b c d e f g h 151 32 Open Games Black to move. a b c d e f g h 157 a b c d e 162 33 f g h Open Games White to move. a b c d e f g h a 163 b c d e 164 34 f g h Semi-Open Games White to move. a b c d e f g h 169 35 Semi-Open Games Black to move. 175 179 36 Closed Games White to move. a b c d e f g h 181 37 Checkmate in Two with a Sacrifice King+ two pieces vs. various pieces King+ two rooks White to move. a b c d 191 e f g h a .�H I> (' d l' 192 r g h King+ two rooks White to move. 195 a h c tl 197 e f g ll a h c d e 19H f g h King+ two rooks White to move. 1 99 a h c J e 204 rj() f g h King+ two bishops White to move. a b c d e f g h e f g h 205 a h c d 209 41 King+ two knights White to move. a b c d 215 e f g h a b c d e 216 f g h King+ two pawns White to move. 219 a h c d e f g h 221 4.� King+ two pawns White to move. a b c d e f g h a 227 h c d e 228 44 f g h King+ rook+ bishop White to move. 4S King+ rook+ bishop White to move. a 239 b c d e 240 46 f g h King+ rook+ queen White to move. a b c d e 244 a b c d e f g h 245 17 f g h King+ rook+ queen White to move. 250 4H King+ rook+ knight White to move. a b c d e f g h a 257 b c d e 258 49 f g h King+ rook+ pawn White to move. 259 a h c d e 264 so f g h King+ bishop + queen White to move. a h c d e f g h 269 il King+ bishop + knight White to move. a h c d e 276 f g h King+ bishop+ pawn White to move. a h c d 281 e f g h a h c d e 282 f g h King+ queen+ knight White to move. a b c d e f g h 287 S4 King+ queen+ knight White to move. 289 a h c d 293 290 e f g h King+ queen+ pawn White to move. 295 298 297 a 299 h c d e 300 f g h King+ knight+ pawn White to move. 302 301 a b c d e f g h 305 i7 King+ bishop + queen vs. many black pieces White to move. a h c d e 312 f g h King+ three pieces vs. various pieces King+ three pawns Black to move. 313 a h c d 3 17 e f g h a h c d e 3 18 f g h King+ two rooks+ piece White to move. 3 19 320 3 21 a h c d e 324 323 60 f g h King+ two rooks+ piece White to move. a h c d 329 e f g h 330 King+ two rooks+ piece White to move. 333 335 62 King+ two bishops + piece White to move. 339 a b c d 341 e f g h King+ two knights+ piece White to move.

There is a great number of such motifs in both attack and defense. Some of these ideas -including the "cross" (a type of double pin), the unstop­ pable attack, closing the trap, the skewer, the x-ray attack, removing the guard, reinforcing the attack, and many others - are not always given the kind of attention they deserve. Many books cover typical attacking methods, but very few provide adequate coverage of defensive techniques. Thi� can be explained from a psychological standpoint: it is more exciting to look for winning moves than it is to try to defend a bad position. However, in order to become a great player, the student needs to know how to both attack and defend. That is why learning typical defensive methods is no less important than knowing attacking methods. Learning the typical ways to defend is not easy. There­ f(lre, in this book most problems are arranged by topic, which will serve as a hint for the student. The next volume in this series, however, will offer problems with no hints, so as to reinforce the skills acquired while reading this book. To become a great player, the student needs to learn both skills: how to attack and how to defend.

In previous volumes, the material was grouped by theme. Now the student must use his or her acquired skills in conditions where the theme of the attacking or defensive maneuver is unknown. This corresponds more closely to the reality of a chess game, in which you don't immediately know which specific aspect of the position will be the defining one (a pin; the poor position of a piece; something else). Students themselves must carefully an alyze the positions that have been created, get a feel for their peculiarities, and work out which specific method of play needs to be used to win material '1r defend the position. The contents of this book are classified by opening type. This will help the beginning player to familiarize himself with the fundamental tactical ideas that are characteristic of a particular opening, as well as with some patterns to he found in the treasure trove of the chess arts. The tactical blows most com­ l n o n ly encountered in the games of beginners are presented with a greater number of examples (in different openings) than are other, rarely encountered tactical ideas. The examples include both very simple, one-move problems and positions 111 which a beautiful maneuver will not be found right away. Some attention has been given to rare opening systems, such as openings where the queen romes into the game early. These kinds of positions occur frequently in the games of inexperienced players, but they are not always given the amount of ullention they deserve in the vast chess literature. When solving the problems in which a defensive maneuver needs to be II nmd, above all the student must see the threat itself (check, double attack, l'll'. ), and- based on that- start to look for the best defensive move (or 111ane u ver) . This defensive idea may be: 1) a counterattack in which you man­ llge to defend and to acquire a material advantage; 11mterial equality; 3) 2) a defense that preserves a defense in a difficult position, when even after the dd'cnsive maneuver your opponent's position remains preferable (but a quick loss is likely if you fail to find the best move).
