Ten Books to Achieve 1800+

Having seen many lists of top ten chess books recommended for players at different levels, I thought it time to reflect on how books contributed to my rise from C Class to A Class. My first non-provisional rating was 1425 when I was in my mid-30s. I played chess competitively many years earlier, but no events were rated. In the late-1970s, I had a USCF correspondence rating. But when I returned to active play after graduate school, the USCF had lost the records of my postal chess.

I rejoined the Spokane Chess Club in late 1995 and played in my first rated OTB event in March 1996. In October, I played my sixth event and no longer had a provisional rating. By the end of the year, my rating had risen to 1495, but would not rise above that point until 2002. I remained in C Class until fall 2006. While on this plateau, I was gaining both knowledge and skills, but rating progress was slow. Too much online blitz may have held me back.

My journey from wholly ignorant beginner in the late-1960s, to competitive high school player in the late-1970s, to active C Class club member in the mid-1990s involved a lot of book study. Further progress from C Class in my 30s to high A Class in my early 50s included many books, active play, private lessons, chess videos, and I also started coaching elementary students in 2000.

It is no easy matter to choose ten books. By the time I reached A Class, I owned close to 300 chess books and there are very few I had not spent some time reading. At the same time, there are also very few that I read wholly. Some books, or my manner of reading them, may have held me back (just as hundreds of three minute blitz games every month may not have helped me).

The Ten
In November 1996, I played in the Washington Class in Federal Way. There was a book seller set up in one of the rooms near the playing hall. I spent a bit of time there talking with David Weinstock, owner of ChessMate. In our discussions, he recommended a book to me. I was skeptical. The title sounded more basic than my own self-assessment of my needs. Nonetheless, when I found the book at Auntie’s Bookstore when I was back in Spokane, I bought it and started to read it. It was transformative.

Consider my list of ten, pictured above and described below, as a provisional suggestion rooted in experience. What worked for me may or may not work for you. Read all recommendations with skepticism, but also with openness to trying something that might help. There are no magic books guaranteed to improve your chess, but only a few will fail to teach you something of value.

1) Georges Renaud, and Victor Kahn, The Art of the Checkmate (1953) was the book David suggested, and is my first recommendation. Having spent many hours in the 1970s learning the basic checkmates with heavy pieces and even two bishops, and having delivered many fine checkmates in many games, it was hard to believe there was much I could learn from such a book. Reading it, however, exposed me to new checkmate patterns, including some that I had seen, but not absorbed, from a book I studied in 1975: Irving Chernev, The 1000 Best Short Games of Chess (1955). Renaud and Kahn not only taught me new patterns, but they gave me a framework for thinking about checkmate and checkmate threats.

As David Weinstock had, I began to recommend The Art of the Checkmate to any and all who would listen, and also to many who ignore what I say. I still do. This book helped me, and it can help you. But there are other books that could substitute, and might be even better. Victor Henkin, 1000 Checkmate Combinations (2011) takes a slightly different approach. It also teaches an abundance of vital checkmate patterns and greatly exceeds Renaud and Kahn in the amount of study material. Antonio Gude, Fundamental Checkmates (2016) is another option. It is comprehensive and to an extent combines the approaches of Henkin with that of Renaud and Kahn. One can find dozens of other books on checkmate patterns, but these three stand above the others. Get one of them, or even all three.
Vital
2) For a year or longer, Lev Alburt, Chess Training Pocket Book: 300 Most Important Positions and Ideas, 2nd ed. (2000) was my bedside reading. I read it cover-to-cover twice. Alburt’s book was the only tactics book I finished prior to early 2023 when I finished all 1320 exercises in Sergey Ivashchenko, The Manual of Chess Combinations (1999). It is not an ordinary tactics book for practicing basic ideas, but rather, a small set of carefully chosen positions with tactical and positional concepts. It also has a small number of vital endgame positions.

Many grandiose claims have been made by different authors about the legendary 300 positions, but there should be no doubt that careful and deliberate study of a small number of carefully selected positions will take your game up a notch. Alburt’s book helped me. A few years after completing it, I began study of another book focused on 300 carefully selected positions: Rashid Ziyatdinev, GM-RAM: Essential Grandmaster Knowledge (2000). More recently, Thomas Engqvist has gained my attention, now with a trilogy of books containing 300 in the title.
An Idea Worth Considering

3) Quantity matters, too, when it comes to tactics training. A classic that has lifted the skills of generations of chess players has also been part of my training. Fred Reinfeld, 1001 Winning Chess Sacrifices and Combinations (1955) deserves a place in every chess player’s library. In 2008, I spent quite a bit of time playing these positions against the computer. Often I could find the tactic, achieve a clearly superior position, and yet still fail to defeat HIARCS (see "Where the Rubber Meets the Road"). Reinfeld organizes the chapters by themes—forks, pins, double attacks, and so on. I set my database containing these positions to open randomly so I did not know which theme to look for. But I also use the book, either solving from the diagrams or sometimes setting up the positions on a board.

Endgames have been vital to my success. In 2007-2008, I invested a lot of time teaching some elementary rook endings to my top student, the strongest third grader in my city. That summer, in the Spokane City Championship, I played two rook endings against FM David Sprenkle, drawing one game.

Currently, I’m on a collector’s quest to have 64 endgame texts in my personal library. The quest stems from my enjoyment studying positions with few pieces, my conviction that endgame knowledge is vital for all skill levels, and my involvement in an online community of book lovers, Chess Book Collectors on Facebook. During my rise from the 1500s in 2002 to high-1900s in 2012, much time was invested in endgame study.

4) The endgame book that did the most for me was Mark Dvoretsky, Dvoretsky’s Endgame Manual (2003). As one of ten books to recommend to class players, Dvoretsky is a controversial choice. Many players find it too difficult for anyone below master. Poppycock! Chess books are not novels. One does not read every word. Read the part that makes sense and push through a bit that stretches and challenges you. I have read the long chapter on pawn endings in Dvoretsky’s Endgame Manual several times and have flash cards containing the 48 blue diagrams that I use for review, study, and teaching (see "Pawn Endings Flash Cards"). I’ve struggled through perhaps half of the chapter on rook endings and made flash cards for the first 24 blue diagrams. Other chapters I have dipped into from time-to-time.

During the years spent studying Dvoretsky’s Endgame Manual, other books have also supplemented my work. These include, Bruce Pandolfini, Pandolfini’s Endgame Course (1988); Jeremy Silman, Silman’s Complete Endgame Course (2007); Karsten Müller and Frank Lamprecht, Fundamental Chess Endings (2001); and several others. My top recommendation for those looking to begin endgame study is Yury Averbakh, Chess Endings: Essential Knowledge (1993). There are many choices. Choose that one that you like, but do not neglect the endgame. Make endgame study a priority if you want to play better chess.
Splurge
5) Jacob Aagard, Excelling at Technical Chess (2004) also concerns the endgame. However, it is distinct from the endgame manuals listed above. The core of the book focuses on “seven technical tools”—schematic thinking, weaknesses, domination, do not hurry, passed pawns, how to arrange your pawns, and freaky aspects. Aagaard develops each of these ideas with compelling prose and detailed game analysis. As he states in the beginning, this book follows an approach that has made Mikhail Shereshevsky, Endgame Strategy so highly regarded. The technical tools are worthy of detailed attention, and I hope to find time to explore them in more detail. I blazed through this book is a couple of days, reading all the prose and glancing superficially at the game analysis. However, this superficial reading was enough to transform my game. My endgame play became more resilient. Formerly, I would often offer or accept a draw in seemingly equal positions. After reading the book, I play out most positions to the end, often lone kings. If there is any reason to play on—an imbalance, a weakness of any sort in my opponent’s position, even a better king position—a draw is anathema unless it secures a tournament victory.

Annotated games have always been a regular part of my chess study. In my youth, I spent many hours playing through games from three GM tournaments that resulted in books that I purchased: San Antonio, 1972; Leningrad, 1973 (the 42nd Soviet Championship); and Wijk aan Zee, 1975. In addition, I bought and still have two books by David Levy that were collections of games by specific players: Karpov’s Collected Games: All 530 Available Encounters, 1961-1974 (1975); and Gligoric’s Best Games, 1945-1970 (1972). All these books influenced my play as a teenager as I sought to imitate the play of the world’s elite.

6) In my 40s, I had many more chess books to choose from and studied annotated games from many of them. One source of such games that I returned to frequently is Garry Kasparov, My Great Predecessors, 5 vols. (2003-2006). Kasparov culls some of the best insights from many years of chess literature and presents many of the most important games of every world champion before him, as well as many contenders for that title who fell short. Chess history offers a reliable foundation for the development of chess skill. Although Kasparov does a poor job of documenting his sources (see my Patriots and Peoples blog for examples of sourcing problems in the writing of US history), the series remains an important practical overview of chess history.

7) Paul Morphy’s games are particularly useful to chess players who want to play well. Perhaps one day I will be able to report that I have played through every one of his available games. So far, I have been through at least one-third of them, some of them many times. His eighteen tournament games have been imposed by me on some two dozen students, who have been through all of them. I’ve shown the Opera game to students at least one hundred times and of course know it fully. For insights into Morphy’s play, few books are in league with Valeri Beim, Paul Morphy: A Modern Perspective (2005). This book has enriched my study.

8) Chess Informant was long the indispensable source for current master games from before I took up the game in the 1960s into the twenty-first century. Now, of course, these games are readily available from many sources. In 1996, as I was coming back to chess with some seriousness of purpose, I was curious about Informant, which I had seen only in the USCF sales catalog. At the Washington Class, however, David Weinstock had some on the table. He allowed me to look at them and we talked about how they were organized. A month or so later, I included Informant 64 in an order of books from USCF sales. It aided my correspondence play in a concrete way (see "Playing by the Book"). More importantly, learning the Informant system of codes changed my thought processes during play. There are so many things that one contemplates during a chess game while looking for the right moves or the correct plan. Sometimes these thoughts are noise that interferes with clear focus on what matters. To an extent, the limited analytical possibilities in the Informant codes distills chess down to things that really matter in the quest for advantage.

As I grew as a player, Chess Informant was a useful tool. Today’s Informants are changing with the information explosion and are oriented more towards the needs of class players than they were in the past. Give them a try.
A Growing Collection
Of course, I did not rise from C Class to strong A Class without studying the works of Jeremy Silman. His endgame book is already listed above, although it was less useful to me than Dvoretsky. In fact, the day I bought it, I read everything through the section on B Class, finding very little that I did not know. Silman’s endgame book has done more for my teaching than for my own progress as a player. That’s plenty! His writing is compelling and many of his metaphors and personal anecdotes are unforgettable.

I bought and read (partly, of course) How to Reassess Your Chess, 3rd. ed. (1993); The Reassess Your Chess Workbook: How to Master Chess Imbalances (2001); The Amateur’s Mind: Turning Chess Misconceptions into Chess Mastery, 2nd ed. (1999); and The Complete Book of Strategy: Grandmaster Techniques from A to Z (1998). When it finally came out, I added How to Reassess Your Chess: Chess Mastery through Chess Imbalances, 4th ed. (2010), but my rating had risen above 1800 before then.

9) Of these books, Reassess Your Chess and the companion workbook were most useful in helping centralize imbalances in my thinking. When I need to win a tournament game, seeking imbalances from the very first move often proves vital.

The Complete Book of Strategy did nothing for my game and very little for my teaching. Its usefulness has been so slight that I struggle to show proper supportive enthusiasm when a young student has shown me that they just acquired it. I must remind myself that there is a difference between this book’s presence in a chess library of more than 400 volumes that includes several dictionaries and encyclopedias, and a chess library for which this book is the first book acquired. It is a good book, even though it does not meet my needs.

What about the Opening?

In high school, I spent many hours studying lines in I. A. Horowitz, Chess Openings: Theory and Practice (1964). In the 1990s, Walter Korn, and Nick DeFirmian, eds. Modern Chess Openings, 13th ed. (1990) took its place. Even more time was spent on opening monographs, including several on two related variations of the Sicilian Defense that feature an early e5 push by Black. There is some evidence this study hurt my game, or at least retarded my improvement. I tried to memorize lines and often faltered when my opponents deviated from the lines that I knew.
Use at Your Own Risk

In 2003, I began to switch from the Sicilian to the French as my primary defense against 1.e4. The French Defense is not superior to the Sicilian. It might even be a worse choice, but for me it marked a shift in how I approached opening study. Rather than grinding through lines in a book, I sought understanding of the principles, of basic concepts, such as one finds articulated clearly in José Capablanca, Chess Fundamentals (1921), of the ideas behind the moves. Unquestionably, I learned many lines, but when my opponents deviated from these, I was prepared. My play improved.

Detailed opening study and learning concrete lines has aided my preparation for specific opponents in several cases. At a crucial moment while still a B Class player, I won the Spokane Contender’s tournament, earning a shot at the title of Spokane City Champion. Expectations of victory were nearly non-existent. No one expected a B Class player rated in the 1730s to prevail over FM David Sprenkle, rated in the 2250s, down considerably from his peak. As preparation, I spent close to 40 hours on two semi-obscure variations: the Raphael variation against the Dutch Defense for when I had the White pieces, and a seemingly risky Nh6 idea for Black in the French Advance. It took Sprenkle 72 moves to compel my resignation in the French, and I drew my second game with White. It was a very good day.

Most of the time in tournament play, however, such extensive opening preparation is more of a crap shoot. Unless an opponent walks into your pet line, where is the benefit? Tactics win and lose games. Endgames keep chances alive as players grow weary or hungry.

10) Hence, my tenth recommended book is one that I’ve read very little, but that exemplifies how I have come to believe opening study should be pursued. Reuben Fine, The Ideas Behind the Chess Openings (1943) is out of date in terms of the line presented, as should be expected. But, players of the French Defense well-know that White’s pawn on d4 is always a target. The Sicilian Defense is always grounded in creating pawn imbalances and active piece play in the quest for equality and even winning chances.

Other Books

Many other books helped me in my successful quest to reach A Class, and remain there for fourteen years so far, as well as my quest to rise into Expert Class, falling just short and less a goal in my 60s than it was in my mid-50s. Learning drives me. My knowledge continues to grow even as my performance in competition is less consistent.

Rook and Bishop Checkmate

Lesson of the Week

Most of my students this week are receiving instruction in checkmate patterns employing rook and bishop. Most of the exercises feature a queen sacrifice to expose the king. I have drawn several positions from Victor Henkin, 1000 Checkmate Combinations, trans. Jimmy Adams and Sarah Hurst (2022) and several more from Georges Renaud and Victor Kahn, The Art of the Checkmate, trans. Jimmy Adams (2015). I also culled some positions from databases. For discussion of these books, see "Learning Checkmate (Or Teaching It)" and "Two Old Books (and one new)".

This position is published in my own Checkmates and Tactics (2019).

White to move. Mate in three.
This mate in five has stymied many of the students.

White to move
This mate in three is easier.

White to move
Morphy's famous queen sacrifice against Louis Paulsen in 1857 leads a series of imitators offered in Renaud and Kahn, The Art of the Checkmate.

Black to move
Samuel Boden followed Morphy's example to get a winning attack with multiple checkmate threats from this position.

Black to move

In all, I prepared 18 positions, but no students have seen them all. Some of my younger beginners received a worksheet with three mate in one and three mate in two.

This position was on a worksheet for older or more advanced students in my after school chess club. It comes from a game I played against Crafty on the Chessimo iPad app.

White to move
How many can you solve?

Move Order

The exercises at the end of each chapter in Victor Henkin, 1000 Checkmate Combinations (2011)* are not sequenced in order of difficulty. Rather, as the author explains in the introduction:
Easy examples deliberately alternate with more complicated ones. The "lottery" principle of the lucky ticket makes the solving of exercises more like the process of searching for a combination in a tournament game. (9)
Preceding two that were solved easily in only a few seconds were one that I failed with the wrong move order, missing a key subtlety, and then one that I made more complicated than it was.

The first was Vladimirov -- Kharitonov 1977 from the Soviet Young Masters.

White to move

I started with the bishop check, failing to consider that capturing the bishop is not obligatory.

Then one of Henkin's own games against Mudrov, 1956. I could not find this game in a database. In fact, Viktor Khenkin's games in the Chessbase database are limited to ten games from a single event.

White to move

This first move that I considered is correct, but I talked myself out of it as I examined Black's choices and defensive resources against one mate threat, completely missing the other mate threat.


*See "Two Old Books (and one new)", which also has a note on the variability of the spelling of Henkin/Khenkin.

13 February 2022

Two Old Books (and one new)

Koltanowski, George, and Milton Finkelstein. Checkmate! The Patterns of the Winning Mating Attacks and How to Achieve Them. New York: Doubleday and Co., 1978.
Tal, Mikhail, and Victor Khenkin. Tal’s Winning Chess Combinations: The Secrets of Winning Chess Combinations Described and Explained by the Russian Grandmaster Mikhail Tal, trans. Hanon W. Russell. New York: Simon and Schuster, 1979.


Checkmate! (1978) and Tal’s Winning Chess Combinations (1979) are remarkably similar in approach. Each takes an individual piece and offers game conclusions where that piece delivers the check that is mate. Then, individual chapters concern certain groups of pieces: both texts have chapters on two rooks, rook and bishop, rook and knight, two bishops, two knights, and queen and knight. Tal and Khenkin* continue this scheme with queen and bishop, queen and knight, and three pieces. In contrast, Koltanowski and Finkelstein offer chapters on certain patterns—Boden’s Mate, Epaulettes Mate, Long Diagonal Mates, Greco and Damiano Mates, and a chapter on double check. These pattern-oriented chapters are followed by chapters arranged by the piece that is sacrificed to set-up checkmate. There are additional chapters on pawn promotion, drawing resources, and how masters use checkmate threats.

There is a difference in the expectation of the target audience evident in advice about how to read the books. Koltanowski and Finkelstein repeatedly suggest that a reader should set up the position on a board and play through the moves in order to plant the patterns into memory. Tal and Khenkin, in contrast, suggest that readers study the book without a chess board to improve visualization skills, using a chess board "when you're really stymied" (14).

Legall’s Mate appears in both books. Tal and Khenkin have it in the chapter on three pieces, while Koltanowski and Finkelstein place it under queen sacrifices. These books differ on the game score of Legall — St. Brie, as well as the date. Tal’s Winning Chess Combinations has the game played in 1787 when Legall was 85 years old (351). Checkmate! states that the opening trap was first recorded about 1750, but does not explicitly state the game was played then (197-198). Koltanowski’s penchant for dubious stories makes its appearance here in the claim, “Légal was one of the first players to record his games” (197). If he recorded his games, what happened to them? Today, we cannot even be certain of the moves in the sole surviving example of Legall's play.

Checkmate!

Checkmate! was brought to my attention in response to my assertion in the Facebook group Chess Book Collectors that the best books for teaching checkmate patterns are George Renaud and Victor Kahn, The Art of the Checkmate; and Victor Henkin, 1000 Checkmate Combinations (see below). My claim provoked some interesting discussion. One commenter identified Checkmate! as a book that helped him learn these skills. Bruce Pandolfini also commented that Milton Finkelstein "was a wonderful chess teacher". On the strength of such recommendations, I found a copy and bought it.

The chapters in Checkmate! typically begin with some elementary illustrations and an impressive combination from master play. The authors describe conditions and rules for executing the checkmate in question, often producing numbered lists. For instance, the "four conditions necessary for mate with a rook":
1. The enemy king lacks escape squares.
2. A rook can attack it on a rank or a file.
3. The rook is immune from capture.
4. The rook check cannot be blocked by the interposing of a protected piece or pawn. (41)
The bulk of each chapter consists of exercises with a number of blanks on which a student can write the moves--workbook style. The introduction of each exercise typically offers clues, and in some cases the final position is shown. The book contains a bit over 550 exercises in total. Answers are in the back of the book. Here is an example from the chapter, "Boden's Mate", that is simple when you know the pattern, but has vexed many of my students over the years (151).

White to move

Often there are historical anecdotes about a player whose combination is featured. These anecdotes in Checkmate! are entertaining, but unreliable. We learn, for instance, that Akiba Rubinstein was confined to Berlin during World War I, "went bankrupt and then developed a persecution mania that broke his powers of concentration" (47). A more credible work, Akiba Rubinstein: Uncrowned King (1994) by John Donaldson and Nikolay Minev, places Rubinstein in Warsaw, limited to a playing local opponents in that city and in Lodz. Donaldson and Minev offer crosstables and games from the war period. They also note that Rubinstein married in 1917 and had a son born in 1918, both events taking place in German occupied Warsaw (254). There should be no question that Rubinstein's postwar play was inconsistent, as suggested by Koltanowski and Finkelstein, but they leave the impression that he did not play at all after the war. In fact, he won several strong tournaments in the 1920s. His performance in St. Petersburg in 1914 suggests that inconsistency cannot be wholly pinned on difficulties during the war years.

Historical errors are distracting, but do not destroy the book's pedagogical value for learning checkmate patterns. Nor do the errors in Checkmate! make the book unique. The list of errors that could be produced from thorough fact checking of Renaud and Kahn also would be lengthy (see "Pillsbury's Mate").

One of the simple illustrations of a final check by a rook in Checkmate! is identical in concept to one that I use often with my beginning students, and with which I became acquainted through Bruce Pandolfini, Pandolfini's Endgame Course (1988).

White to move

Classifying and organizing checkmate patterns is not a simple matter. In my own efforts, guided by half a dozen books and a few websites, I separated the dovetail and swallowtail checkmates from epaulette, listing all three as checkmates with the queen. Renaud and Kahn use the term Guéridon for the two bird mates and include this pattern with epaulette. Koltanowski and Kinkelstein lump them together under epaulette mate, but do not limit the pattern to a final check with the queen. This position credited to a Russian player surnamed Usachev illustrates (67-68).

Black to move

1...Bc3 2.Ke2

Black could avoid checkmate at the cost of a rook, the authors note. Stockfish shows that both rooks will disappear if Black plays the superior move 2.Kc1. After 2.Ke2, Black has a mate in two that starts with a queen sacrifice and ends with a knight check. Four White pieces occupy the king's escape squares, serving as ornament rather than protection.

Checkmate! includes a substantial number of checkmate examples. Had I acquired it when it was first published during my teen years and devoted myself to working through the book, I may have become a much stronger player.

Unfortunately, whatever the merits of the book, the authors were ill-served by their publisher. The very first diagram in the text is wrong (2). It appears that the image negative was flipped before printing--there is a dark square in the lower-right corner. Black's 4...K-K4 is an illegal move as there is a pawn on that square. The mismatch between the original position and the final position showing checkmate with a pawn alerts the attentive reader to the problem, so the error can be overcome. The publisher also exercised poor quality control over the printing process. Too much ink was allowed to flow, creating many pages where the dark squares are so dark that the Black pieces on them nearly disappear. Many pages have crystal clear diagrams, but a large percentage are dark and even blurred from inattention by the printer. These problems will be even worse in the Ishi Press reprints, which are notorious for poor print quality. 

Tal's Winning Chess Combinations

My Facebook assertion in favor of the value of Henkin, 1000 Checkmate Combinations was grounded in study of Tal and Khenkin, Tal's Winning Chess Combinations, which I have found quite good. My view also stems from superficial examination of the newer translation in Kindle format. Others have assured me that the newer edition is a better translation of The Last Check (more on that below).

Tal's Winning Chess Combinations is more challenging than Checkmate! This position from Adams -- Torre, New Orleans 1920 (given as 1921 in the text) and the winning idea is richer than most of the combinations in Koltanowski and Finkelstein (19).** 

White to move

White offered his queen for six consecutive moves in the effort to divert Black's queen from the defense of e8. The idea reappears as exercise 8 (37) from Guldin -- Bagdatev (1963), a position I remember from Lev Alburt, Chess Training Pocket Book, 2nd ed. (2000).

The initial example in each chapter of Checkmate! is usually comparable, but the rest of each chapter is less demanding. It did not take me more than ten minutes to blaze through the 13 exercises in the rook chapter, and every example was a forced checkmate. In many of the examples in Tal's Winning Chess Combinations, mate threats can be parried with significant sacrifice, still leading to a lost game.

Tal's Winning Chess Combinations also has a clearer demarcation between the instructive section and the exercises. Each chapter begins with diagrams showing the elementary pattern, and then proceeds through instructive and entertaining examples. Most chapters repeat this sequence with more checkmate patterns and game fragments. The object is showing a range of possibilities with the piece or pieces in question. As in Checkmate!, Tal's Winning Chess Combinations presents game endings where a queen did not deliver the final check in an epaulette mate.

This one is presented as Korchnoy -- Petrosyan 1965 (281).

White to move

White has a forced checkmate in four moves with a queen sacrifice on the second.

The bulk of the book is devoted to instructive examples. An idea is presented, then a few position, then a variations on the idea and more illustrations. The Adams -- Torre position above is the ninth instance of a combination exploiting a weak back rank in the chapter on the rook. This chapter begins with a simple illustration of a back rank checkmate. The instructive portion offers fifteen combinations to divert defenders from protecting the vulnerability. Diversion is combined with a second threat in some combinations. Further examples offer other tactical ideas, such as "line interference" in Reti -- Bogoljubow 1924 (22).

White to move
After 24.Bf7+ Kh8 25.Be8, Black resigned.

Tal's Winning Chess Combinations is notable for how it builds understanding of many possibilities related to a simple pattern. Applying what we know from backrank checkmates, the author notes that kings can be hemmed in by their own pieces on a file as well as rank. Even a file away from the edge of the board can become a deadly corridor. Goldenov -- Zakharian 1960 is a memorable example (34).

Black to move
1...g4 2.Kf4 Ra5 3.e5 Ra4+ 4.e4 Ra3 and White resigned.

Tal and Khenkin's chapter on the rook offers 45 instructive positions and then 17 exercises at the end of the chapter for the reader to solve. This abundance contrasts with a total of 13 exercises following four instructive examples in Koltanowski and Finkelstein. Checkmate!, however, offers 25 chapters to the 14 in the other text. The total of 271 exercises in Tal's Winning Chess Combinations are far fewer than more than 550 found in Checkmate!, but many offer greater challenge. On balance, I prefer Tal's Winning Chess Combinations, but expect to lift some examples from Checkmate! while creating worksheets for my students.

The New Book

Henkin, Victor. 1000 Checkmate Combinations, trans. Jimmy Adams and Sarah Hurst. London: Batsford Chess, [2011] 2022.



1000 Checkmate Combinations is a newer translation of the same Russian book as Tal’s Winning Chess Combinations. As such, the two books have considerable overlap. However, the differences are extensive. Both books have the same fourteen chapters, although the sequence differs. Each chapter offers a series of instructive game fragments and studies and then conclude with exercises at the end of the chapter. Tal’s Winning Chess Combinations has a total of 271 exercises, but the newer translation expands these to 456. 1000 Checkmate Combinations was published just over ten years ago, but has been out of print most of that time, although a Kindle edition was available. It was brought back into print in February 2022.

I cannot assess the quality of the translation. I lack both the resources (a copy of the Russian edition of The Last Check) and the competence (knowledge of Russian). However, I prefer the recent Batsford edition for several reasons. Tal's Winning Chess Combinations blurs the lines between Khenkin's work and Tal's contribution. 1000 Checkmate Combinations explicitly states that the book is Henkin's work. The title page reveals that Victor Henkin owns the text copyright. Batsford also asserts copyright ownership. The publisher owns all rights in the 1979 translation by Hanon Russell; there is no mention of the authors on the copyright page.

Tal’s Winning Chess Combinations begins with an Introduction: “Don’t Reinvent the Wheel”, co-authored by Tal and Khenkin (9-14). 1000 Checkmate Combinations has “Don’t Reinvent the Bicycle” by Tal (5-6) followed by “Before You Open the Book” by Henkin (7-9). The joint introduction in the earlier translation contains most of the content presented in the two introductions in the later text. In addition to clarifying authorship, the most notable differences are that Tal ended his introduction in the Batsford edition with a quote from Richard Réti, Masters of the Chessboard. This quote is absent from Russell’s translation. Russell also inserts Legall’s game into the introduction, while Adams and Hurst do not.

In Tal's introduction to the Batsford edition, we find:
There hasn't been a book like this before in our chess literature. The author has done an enormous amount of work selecting and systematizing the material. An experienced master, who in the recent past himself participated in competitions and had a reputation as a staunch tactician, he has retained a particular taste for the last check. (6)
This text is absent from Tal's Winning Chess Combinations. 1000 Checkmate Combinations is clearly the work of Henkin, lauded by Tal. Henkin's authorship is attested in Vladimir Barsky, A Modern Guide to Checkmating Patterns (2020), which is dedicated to Viktor Khenkin, whose pioneering organization in The Last Check is the model for Barsky's text.

Tal's Winning Chess Combinations presents a decisive mating combination played by Vera Menchik against George Thomas in 1932, and then imitated by David Bronstein against Paul Keres 18 years later (32-33). In both books this combination follows Capablanca -- Raubitschek 1906, to which it is comparable. 1000 Checkmate Combinations adds Tal -- Andersson 1976, where Tal's threats to bring about Menchik's combination provoked a series of exchanges that simplified into an ending with queen against knight and rook (25).

White to move
After the immediate 25.Qh6, the combination falters because Black's resources with 25...Rg8 and 26...Nf8 hold the position together. Tal first set out to remove the knight.

25.Bb6 Rc8 26.Qh6 Rg8 27.Rd4!

Henkin writes, "So Ulf Andersson gives up his queen for rook and bishop, which, however, doesn't save the game" (25).

27...Nxb6 28.Rxd5 Nxd5 29.Rf3

With Tal renewing the mating threat, Anderrson is forced to exchange rooks.

29...Rc3 30.Rxc3 Nxc3 31.Qe3 b4 32.Qa7 Rf8 33.Qc5 Rb8 34.Qd6 1-0

This long combination with checkmate threats parried, but still leading to a decisive advantage is a characteristic of Henkin's work. Both translations of his work bring this out, but the more recent text does so in greater abundance.

Detailed comparison of the first chapter of both books shows that the 45 positions in Tal and Khenkin expands to 62 in 1000 Checkmate Combinations. I count five in the older translation that are missing from the newer edition. My count of 15 in the Batsford edition that are absent from Tal's Winning Chess Combinations reveals there is something askew with my counting (15+5 > 17). But there is no doubt that the newer edition has more material. The 1979 text has three sets of basic patterns followed by examples from games and studies. The Batsford edition has four. Above, I credit Tal's Winning Chess Combinations with showing corridor mates on files as well as ranks. The idea is there, but is is made more explicit in the section found only in the newer book.
Mating situations in which the rook delivers a linear blow can also arise on the files. In these cases it is as if the board does a 90-degree turn. (20).
At the end of the chapter on rooks, the exercises have expanded from 17 to 43 in 1000 Checkmate Combinations.

Although many passages in the two books make it abundantly clear that they are derived from the same Russian text, the language employed differs. The familiar term luft is found in Russell's translation, but becomes "the little window" in the work of Adams and Hurst. Diversion becomes deflection. Line interruption becomes interference.

Some readers will object to the small size of the diagrams in 1000 Checkmate Combinations. They are indeed small at 35 mm. Only a few books have smaller diagrams, such as the training positions in Antonio Gude, Fundamental Checkmates (2016), measuring 34 mm. Other chess books typically have diagrams from 40-50 mm, and the main part of Gude's book comes in at 45 mm. Diagrams in Tal's Winning Chess Combinations are 41 mm. They are 43 mm in Checkmate!

In the Kindle edition of Henkin, the figurines in the notation are a larger font than the text. I have found this ebook difficult to read, but the print text is a delight, even with the small diagrams. At least the diagrams are very clear with appropriate shading of the dark squares and clear pieces.



Notes

*Both Khenkin and Henkin appear as the spelling of this writer's name in different places. I favor the spelling used by the book under discussion. Vladimir Barsky dedicates A Modern Guide to Checkmating Patterns (2020) to Viktor Lvovich Khenkin and offers The Last Check as the English title of the Russian work upon which both Tal's Winning Chess Combinations and 1000 Checkmate Combinations are based. Barsky's book follows the general outline of these two, but with far less instructive material. Rather the instruction is provided as exercises. While Khenkin is the spelling on the cover and title page of Tal's Winning Chess Combinations, games played by the author are presented in the text with the spelling Henkin.

**In all likelihood, this game was analysis, possibly by the alleged victim of the combination as instruction for the alleged victor. See Edward Winter, "Adams v Torre -- A Sham?" Chess Notes (updated 14 December 2021).

Checkmating Patterns

I recently added to my bookshelf A Modern Guide to Checkmating Patterns (2020) by Vladimir Barsky. This book extends the work of two older books that are scarce and therefore expensive: Victor Henkin, 1000 Checkmate Combinations (2011), and Mikhail Tal and Victor Khenkin, Tal's Winning Chess Combinations (1979). The latter two books were published in Russian sometime before the English editions came out. I have a hunch it was a single book with two English editions. Tal's introduction "Don't Re-invent the Wheel" in the 1979 text appears as "Don't Reinvent the Bicycle" in the 2011 version with some differences. 

I have a hardback copy of Tal's Winning Combinations that I bought in the past decade, but passed up a chance to buy the Batsford edition, 1000 Checkmate Combinations. My recollection of when and where I looked at it does not correspond to the publishing date because I think it was a few years before 2011. I failed to comprehend then the significance of my opportunity. There is a Kindle version of the Batsford edition. The diagrams are a bit pixilated, but clear enough on my iPad.

All of these books arrange checkmate patterns according to which pieces effect the execution of the enemy king. Barsky credits Viktor Khenkin, The Last Check with the "methodology" (7). A Modern Guide to Checkmating Patterns is wholly new. Barsky assembles illustrative positions and exercises exclusively from the twenty-first century. This one caught my eye this morning in the opening chapter.

White to move


The position arose in Lenderman,A. -- Gareyev,T., Mesa 2010. Lenderman played 30.Rd6 and Black resigned. The rook's interferes with the defensive contact between Black's queen and rook, threatening Qxb8#.  White's queen is safe from capture because of Black's weak back rank. Any move of Black's rook dooms the knight. Barsky gives 30...Rc8 31.Ra6 Nc4 32.Qxc4 Rxc4 33.Ra8+ with mate to follow (12-13).

A few years ago, when I was reading Tal's Winning Chess Combinations, I was struck by the quality of the examples. Barsky's examples also seem rich with possibilities. The book serves not only to teach elementary patterns, but also to stimulate the imagination.

Khenkin's original approach to discerning and organizing checkmate patterns is worthy of attention. It varies slightly in the three books that I have before me. Listing the table of contents of each of the three will serve to highlight the continuities while also marking slight differences in the approach.

1. The Rook
2. The Bishop

The first two books offer the same chapters, but the sequence differs. The content is similar, but the Batsford edition contains more exercises. In the new book by Barsky, the number of chapters is reduced by combining pawns and the three chapters featuring minor pieces into a single chapter.
