Queen vs. Advanced Pawn

White played an excellent game to reach a simple win and then made two consecutive moves that made it appear that everything prior to that was a fluke. Time was not a factor with 4:19 remaining in a 10-minute game.

White to move
53.b4??=

53.g6 wins quickly.

53...Kxg5 54.Kb5??

Now, Black is winning. Perhaps White saw that both players would promote and failed to anticipate who would have the first check for if Black did, the check would lead to a skewer. Otherwise, this move looks like an effort to lose.

54...h4 55.Ka6 h3 56.b5 h2 57.b6 h1Q 58.b7

Black to move
The technique here is simple, but Black's execution was a bit clumsy. The simple idea that every student should learn is to drive the White king in front of its pawn, then step the king closer. Eventually, there will be an opportunity for checkmate.

With the advanced pawn on the b-file (or g-file), checkmate opportunities come sooner. Black was oblivious to this fact.

58...Qa1+ 59.Kb6 Qb2+

59...Qe5 is better, controlling the promotion square, another element of the basic technique of battling a pawn one square from promotion. To prevent Black from occupying b8 with the queen, 60.Ka7 is forced. Now, 60...Qa5 61.Kb8 Kf6 brings checkmate closer.

60.Kc7 Qg7+ 61.Kb8 Kf6

61.Kf5 was better, stepping closer without restricting the queen's mobility.

62.Ka7 Qg1+

62...Qc7 lead to a more rapid checkmate. Pinning the pawn is a third element of the basic technique.

63.Ka8

Black to move
63...Qg2

Although this move works towards eventual checkmate, less clumsy would have been the simple checkmate in five. 63...Qa1 64.Kb8 Qc3 65.Ka7 Qa5+ 66.Kb8 Ke7 67.Kc8 Qd8#

64.Ka7 Qa2+ 65.Kb6 Qb3+ 66.Kc7 Qc4+ 67.Kd7 Qb5+ 68.Kc7 Qc5+ 69Kd7 Qb6 70.Kc8 Qc6+ 71.Kb8

Black to move
71...Ke7

Black, who has spent many hours teaching the elementary checking technique to young students, could show more finesse and attention to opportunities in the position.

Here, for example, 71...Qc5! forces 72.Ka8 and a mate in three identical to that found in the mate in five above at move 63.

72.Ka7 Qa4+

Better was 72...Qc5+ 73.Ka6 Qb4 (controlling the promotion square via X-Ray) 74.Ka7 and again mate in three.

73.Kb6 Qb4+ 74.Kc7 Qc5+ 75.Kb8

Black to move
75...Kd7

Black knows this checkmate well, but should know also the pattern of mate in two that has presented itself several times earlier in the game. 75...Qa5 76.Kc8 Qd8#

76.Ka8 Qa5+ 77.Kb8 Kc6 78.Kc8 Qc7#

Black was relieved that his opponent threw the game through two consecutive blunders, converting a win to a draw, and then a draw to a loss.

Black showed a simple winning technique, but missed opportunities to end matters more quickly offer some learning opportunities and some positions that might be beneficial teaching young students this fall.

The basic element of this endgame is simple: check until there is an opportunity to move the king closer without allowing the advanced pawn to promote. Prevention includes checks, pins, and controlling the promotion square. Be alert to possible checkmates to show better technique.

64 Endgame Books

It has been a goal of mine to acquire 64 endgame books before I reach the age of 64. That birthday comes soon and I need one more. What shall I add to my existing collection? Will it gather dust on the shelf, or will it be one that I read?
The main shelf

The category of "endgame books" is not perfectly clear. Do works on checkmate patterns fall into this group? I keep those books separate, although checkmate exercises were called "end-games" in nineteenth century chess periodicals and books. I do include studies, although some would put these in a separate category.

There are some classics on my shelves and some books published in the past two months. Most are paperbacks, but there are a few hardcover. Missing from my shelves are four of the five volumes of Encyclopedia of Chess Endings published by Chess Informant. Last summer, seven of the eight volume series edited by Yuri Averbakh were added. I have had the volume on rook endings for several years. In the months since, I've spent some time working through the early chapters on bishop endings.
Part of a second shelf is needed

For decades, the only endgame book in my possession was Irving Chernev, Practical Chess Endings, which I purchased at B. Dalton in downtown Spokane in the 1970s as a high school student. In the mid-1990s, as I was getting back into chess with some seriousness of purpose, I bought a copy of Jenö Bán, The Tactics of Endgames. Even then, my study focus remained largely openings and tactics.

In the twenty-first century, two books provoked serious study of endgames on my part. First, Karsten Mūller and Frank Lamprecht, Fundamental Chess Endings, published in 2001 and acquired that year. Then with purchase of Dvoretsky's Endgame Manual shortly after it was published in 2003, I began to both work on and enjoy endgame study. When I started studying Dvoretsky, I was USCF C Class. Today, it is often suggested that Dvoretsky is too hard for a class player, who should begin with Silman's Complete Endgame Course. Waiting four years for Silman would have deprived me of many hours of productive study. In any case, I rarely read a chess book cover-to-cover. Dvoretsky improved my game (see "Ten Books to Achieve 1800+").

Sometime before then, I had acquired Reuben Fine, Basic Chess Endings, but I always found this book difficult to use with too few diagrams and small print lacking sufficient paragraph breaks. Even so, it was a reference I turned to often when a specific question arose.

As the number of volumes slowly increased, I became a collector, still favoring those that I think I'll read.

The newest book in my collection was published this year and is a reprint, edited with a light hand, of one of the oldest endgame books in existence. Carsten Hansen brought Horwitz and Kling, Chess Studies and Endgames (1851) back into print as part of his Alexander Game Books Classics series.

Knowing and Doing

My opponent's draw offer leads me to believe that he understood that a queen vs. a c-pawn one square from promotion is a draw. Nonetheless, I demanded proof and the opportunity to present it was missed. Alas, my own errors allowed the draw to remain after my opponent's first error, and the queen vs. pawn occurred only because I exchanged rooks when they should have remained on the board.

My individual students saw this endgame last week and then most of them solved some exercises from Georges Renaud and Victor Kahn, The Art of the Checkmate (1953). My afterschool club solved worksheets with checkmate in one. This week, they will see mates in two from some of the same games.

Black to move
56...Rxf6??

Simple counting shows that the next diagram will be reached. I should have played 56...Rc4.

57.Kxf6= Kf4 58.Ke7 g3 59.Kxd7 g2 60.c6 g1Q 61.c7 Qa7

White to move
62.Kd8??

Now, we have reached a position that I know from endgame books. 62.Kc6 was the only move to hold the draw.

62...Qb6??

I know, but did not do. After 62...Ke5-+ 63.c8Q Kd6, White is in zugzwang with a worthless king. In fact, Black has a mate in three.

63.Kd7= Qb5+ 64.Kd8 Qd5+ 65.Kc8 Ke5 66.Kb8 Qb5+ 67.Ka7 Qc6 67.Ka7 Qc6 68.Kb8 Qb6+

White to move
69.Kc8??

69.Ka8=. Knowing this stalemate resource is essential to understanding why a c- or f-pawn against the queen is a draw when the pawn is one square from promotion.

69...Kd6-+

White resigned.



25 May 2022

One Queen Too Many

Four moves after my opponent promoted a second pawn, my rook and queen delivered checkmate while White's two queens idly watched.


How did this come about? Where did White go wrong?

We take up the game after White's 37.Kg5.

Black to move

Black's position seems hopeless.

37...Nxe6+ 38.Bxe6 Kxe6 39.Kh6 e3

White to move

40.Re1??

White needs to push another pawn. 40.g4+-

40...d4= 41.g4 Ke5??

The king is needed elsewhere.

41...Kf7= 42.Rf1+ (42.g5?? Rd6+ 43.Kh5 Kg7-+) 42...Ke6 43.Re1=

42.g5+-

White is back in control.

42...Ke4 43.g6 d3 44.g7 Rd6+ 45.Kg5 d2

White to move

46.Rxe3+??

White spent 31 seconds--half of their remaining time in this 3 2 blitz game on this blunder.

46.Rh1+-

The rook can always remove the first queen and White's pawns are promoting first.

46...Kxe3= 47.h8Q d1Q

White to move

48.Qe8+??

Stockfish offers a long line that essentially leads to a draw by repetition.

48.Qh3+ Kd2 49.Qg2+ Kd3 50.g8Q

Black to move
Analysis Diagram

50...Qc1+ 51.Kg4 Rd4+ 52.Kh5 Qd1+ 53.Kg5 Qc1+

48...Kd2-+

Now Black is winning.

49.g8Q Qg1+ 50.Kf5 Qf2+

White to move
51.Ke5?

White steps into checkmate.

After 51.Kg5 Black has a lot of work to do to convert a one pawn advantage in a queen ending after first forcing White to exchange the second queen for Black's rook. 51...Qg3+ 52.Kh5 Qh3+ 53.Kg5 Qh6+ 54.Kg4 (54.Kf5 Rf6+ 55.Ke5 Qf4+ 56.Kd5 Rd6+ 57.Kc5 Qd4+ 58.Kb5 Rb6+ 59.Ka5 Qb4#) 54...Rd4+ 55.Kg3 Qh4+ 56.Kg2 Rg4+ 57.Qxg4 Qxg4+ 58.Kf2 Qd4+ 59.Kg2 a5-+.

51...Qf6+ 52.Ke4 Rd4# 0-1

Maybe you will find this ending both informative and entertaining.

Endgame Books

As the decade of the twenty-teens comes to an end, I thought it appropriate to consider the value of endgame books. I posted a photo on Facebook of the shelf that holds my collection of endgame books, offering a witty remark about ends and beginnings. I have long been in agreement with Jose Capablanca, Chess Fundamentals (1934) that aspiring players need to begin with the endgame.


I thought it would be a simple matter to list the books on this shelf and one or two other places, and then write brief annotations about all or most. However, the limits of this simple project became clear. Before basic pawn endings, Capablanca presents checkmates. Should checkmate pattern books be on the list? Pandolfini's Endgame Course is listed below and begins with simple checkmates. Why exclude others? 

Then, there is the matter of ebooks. Listed below are a few that are available from Amazon. For beginning chess players, no other author offers clearer analysis and better diagrams that the self-published work of Rodolfo Pardi. And yet, I exclude from the list the many classic texts in my Google Books library that are the result of scanning rare books from libraries. For instance, Johann Berger, Theorie und Praxis der Endspiele (1890) is perhaps the originator of the genre. Why not list it?

So, the list below starts with one shelf of books, listing a few other that might be on that shelf if they fit. As print books, they are the core of the reference materials I turn to frequently while studying or teaching the endgame. Studying the endgame positions in GM-RAM: Essential Grandmaster Knowledge (2000) by Rashid Ziyatdinov, for example, sends me looking through other works because Ziyatdinov offers no solutions. Thomas Engqvist, 300 Most Important Chess Positions (2018) contains many endgames with explanations, but the books on the shelf offer greater detail. I study because I enjoy the process as much as for the benefits to my game.

Alburt, Lev, and Nikolay Krogius. Just the Facts!: Winning Endgame Knowledge in One Volume. New York: Chess Information and Research Center, 2000.

This book is part of a set of seven that claimed to bring secrets of Soviet chess training to an American audience. I have not read it, but the Chess Training Pocket Book that is also part of the series is one of very few chess books that I have read cover-to-cover. And, I've done so twice. 

Averbakh, Yuri. Chess Endings: Essential Knowledge. London: Everyman Chess, 1993.

When someone asks where they should start in their study of endgames, this book is the first that comes to mind. It is short, focused, and written by one of the all-time great chess teachers. Averbakh produced a longer set of books on the endgame that belong in any complete library. I have PDF copies that someone gave me.

Ban, Jeno. The Tactics of Endgames. Mineola, NY: Dover, 1997 [1963].

When I bought this book about the year it came out, my chess library still numbered in the dozens of volumes. I spent some time working through part of it and my play improved.

Barden, Leonard. How to Play the Endgame in Chess. Indianapolis, NY: Bobbs-Merrill Company, 1975.

This book looks good, although I have not spent any time with it.

Chernev, Irving. Practical Chess Endings. New York: Dover, 1961.

I bought this book as a teenager, spent minimal time on chess in my twenties, and returned to serious play in the 1990s after graduate school. For two decades, it was my only endgame book. I studied it a bit in the 1970s, and still pull it off the shelf from time to time. Many of the exercises are composed.

_______. Capablanca's Best Chess Endings. New York: Dover, 1968.

In 2012, after beating me in the match for title of Spokane City Champion, John Julian credited his study of this book for guiding him in an endgame we had played. I bought it later that year, if I recall correctly. In November and December 2020, I worked through ten of the sixty games with my students. Although, in truth, I pay little attention to Chernev's analysis. Capablanca often simply outplayed his opponent from positions that could have been drawn with best play, but errors were made. Good examples of practical play.

De la Villa, Jesus. 100 Endgames You Must Know: Vital Lessons for Every Chess Player, 4th ed. Alkmaar, The Netherlands: New in Chess, 2015.

If any book supersedes Averbakh's Chess Endings: Essential Knowledge, it is this terrific book by Jesus de la Villa. Chessable also has a course based on this book that I understand has been very useful for promoting its innovative approach. Before I had a copy, I watched a video of Magnus Carlsen being taken through the Chessable course. One hundred endgames seems like a reasonable beginning and the explanations are well-written.

Donaldson, John. Essential Chess Endings for Advanced Players. Dallas: Chess Digest, 1995.

I bought this book from the author in February at the only OTB tournament I played this year. I spent my morning coffee time with it much of the next few weeks. It offers good challenging instructive positions. 2020 became a much busier year when my teaching went online, and chess suffered until mid-summer.

Dvoretsky, Mark. Dvoretsky's Endgame Manual. Milford, CT: Russell Enterprises, 2003.

This book is not for beginners, and some have suggested that it is only for players substantially stronger than me (i.e. masters). Of course, I've beaten masters quite a bit in online blitz, and some in online correspondence. I've also held my own in two rook endgames with a FIDE Master in the 2008 Spokane City Championship. Credit time spent with this book. It is a standard reference that I use frequently. I have a newer edition in Kindle format on my iPad. The most recent edition has been revised by Karsten Muller because Dvoretsky is no longer with us. See "Pawn Endings Flash Cards".

Emms, John. Starting Out: Minor Piece Endgames. London: Everyman Chess, 2004.

I keep pulling this book off the shelf with some intent to study, but then doing something else.

Erwich, Frank. Endgame Tactics: Magnus Carlsen. Alkmaar, The Netherlands: New in Chess, 2018. ebook.

Frank Erwich has produced a series of short ebooks for New in Chess. The general pattern is to offer one hundred exercises from the games of the featured player. A diagram is presented with the solution on the next page. I work through a problem or two every now and then. I'm 45% through this one.

Fine, Reuben. Basic Chess Endings. New York: David McKay, 1969 [1941].

The formatting of this book makes this book hard to read. There, I have said it. For its day, it was a mammoth achievement. I mostly look at it when someone else has referred to it. Most recently, Harold van der Heiden referenced it in his Endgame Study Database in an endgame I was studying (see "Textbook Ending"). Dvoretsky proved more useful.

Fishbein, Alex. King and Pawn Endings. Macon, GA: American Chess Promotions, 1993.

Someone was raving about this book, and it seemed to offer insights helpful with one or two of the exercises in GM-RAM. I found a copy online and ordered it. I found it useful. I might spend more time with this book in the future. Unfortunately, it is out of print.

Flear, Glenn. Improve Your Endgame Play. London: Everyman Chess, 2000.

I have probably opened this book a few times, as well as the other two in the set. 

_______. Mastering the Endgame. London: Everyman Chess, 2001.

_______. Test Your Endgame Thinking. London: Everyman Chess, 2002.

Kasparian, Genrikh Moiseyevich. 888 Miniature Studies. Belgrade: BeoSing, 2010.

Genrikh Kasparian has another book on the endgame that I should buy, Domination in 2545 Endgame Studies. It is not cheap in a quality edition. These studies are challenging miniatures (problems with few pieces). When I first acquired a copy, I spent a bit of time most days for several weeks working through the problems. Terrific book, but not necessarily ideal for improving practical play.

Levenfish, Grigory, and Vasily Smyslov. Rook Endings. Dallas: Chess Digest, 1971.

Vasily Smyslov was a terrific endgame player. Positions that he played correctly appear in standard reference works, and you can bet the authors of these books studied this one. I dip into it from time to time.

Matanovic, Aleksandar, et al. Encyclopedia of Chess Endings (Queens). Beograd: Sahovski Informator, 1989.

Part of a five volume set. I picked this book as my prize after a blitz tournament at the Spokane Chess Club a few years ago. It is a terrific reference work.

Mednis, Edmar. Practical Rook Endings. Coraopolis, PA: Chess Enterprises, 1982.

This book is another that I bought from John Donaldson in February. I have not made the time to study it, but Donaldson told me the time would be rewarded.

Minev, Nikolay. A Practical Guide to Rook Endgames. Milford, CT: Russell Enterprises, 2004.

This little book belongs in a small collection of books like Averbakh's Chess Endings: Essential Knowledge. It goes to the heart of the subject in a few pages. terrific beginning point before getting lost in the rook endings in Dvoretsky.

Muller, Karsten, and Frank Lamprecht. Fundamental Chess Endings: A New Endgame Encyclopedia for the 21st Century. London: Gambit Publications, 2001.

This book has served me well as a companion to Dvoretsky's Endgame Manual. It is a terrific endgame reference work that sometimes explains matters more clearly than Dvoretsky.

Nunn, John. Nunn's Chess Endings, vol. 1. London: Gambit Publications, 2010.

When Borders Books opened in my city, they started by stocking nearly everything. Then, the local market affected the selection, and there was a diminishing supply of vital texts like chess books and the works of William Faulkner. In the last few months of its existence, these two were the only ones in stock that were worth having and I did not already own. Owning copies is one thing; reading them is another. Nunn's books are challenging.

_______. Nunn's Chess Endings, vol. 2. London: Gambit Publications, 2010.

Pandolfini, Bruce. Pandolfini's Endgame Course. New York: Fireside, 1988.

I worked through much of this book in a short period of time about twenty years ago, and many of the fundamental positions became central to my teaching. I gave away my copy as a prize at a youth chess tournament. A few years later, I acquired another copy.

Pardi, Rodolfo. Opposition and Critical Squares. Self-Published, 2014. ebook.

This book concerns one elementary chess endgame position and a few that are derived from it. The diagrams are the best I have seen in an ebook. This explanations are clear. Perfect choice for young players starting out.

Polgar, Laszlo. Chess Endgames. Koln: Konemann, 1999.

This is part of a set of three massive reference works that one might assume formed part of the curriculum for training the Polgar sisters. However, Susan Polgar has claimed online that at least one of them was her work when she was a teenager. Chess Training in 5334 Positions is the best known, and the most widely available. This endgame book has more than 4000 endgame positions organized by 171 themes. It has been a useful resource.

Seirawan, Yasser. Winning Chess Endings. London: Everman Chess, 2003.

During the broadcast of a grand master chess tournament a few years ago, Wesley So came into the broadcast booth with Yasser Seirawan to go over the game he had just won. Then they talked more generally. So credited the Winning Chess series that Seirawan wrote with having helped him when he was starting out. I find the story credible and think that Seirawan's books are all very good. They are not comprehensive, but well-written and the examples are quite instructive.

Shereshevsky, Mikhail. Endgame Strategy. London: Cadogan Chess, 1994 [1985].

I bought this book a few years ago from John Donaldson who always brings a batch of new and used books to a tournament in my city that he has attended twenty times or so. Most often, he wins the event. He sells these books at low prices. Shereshevsky's text has a good reputation, but my time with it has been too limited to offer much insight.

Silman, Jeremy. Silman's Complete Endgame Course: From Beginner to Master. Los Angeles, Siles Press, 2007.

Jeremy Silman structures this book as the endgames a player should know at different rating levels. The overall structure tends toward superficiality, which makes it the perfect resourse for those who do not want to spend much time studying. I find the positions that Silman lists for master and above where my current study takes me. I worked through the whole book up to my rating level in the space of a few hours the day I bought it. Now, it mostly gathers dust. Nonetheless, it has influenced me substantially in the material I choose to teach. Silman convinced me to cease teaching checkmate with bishop and knight as a regular practice, and he offers no instruction concerning that elementary checkmate in this book. He also convinced me of the importance of the Philidor and Lucena rook endings.

I used this book as supplementary material while studying some of Smyslov's own rook endings via Dvoretsky.

Stripes, James. Essential Tactics: Building a Foundation for Chess Skill. Self-Published, 2017. ebook.

This book was my first self-published book through Amazon. Previously, I had used the copiers and spiral binding services at Kinkos (now FedEx Office). It is not an endgame book, bit rather a primer on tactics aimed at beginning players that was inspired by the success that I found taking some young students through Bruce Pandolfini, Beginning Chess. Every position has ten or fewer pieces and a simple tactic, the idea I got from Pandolfini. I composed slightly more than 130 of the 150 exercises included here. However, after solving the tactic, one often finds an endgame where there may be a series of only moves. I offer reasonable explanations of these endings in the text.

Van Perlo, C. G. Van Perlo's Endgame Tactics, new ed. Alkmaar, The Netherlands: New in Chess, 2014.

The exercises in this book are unmatched and the quality of the analysis is first rate. However, this is more of a workbook than textbook. It offers not systematic study of endgame themes, but rather a generous collection (1300+) of problems to challenge and entertain.

Endgame Battle

In Wednesday's Morning Membership tournament, my round two game ended quickly because my opponent hung a piece early and gracefully resigned on move 20. That gave me time to watch Twitch, where Chris Bird was broadcasting the event. The top rated played in the event was struggling against a player who has given me trouble. The lower rated player exchanged queens into an endgame that Chris was sure should be winning for Black (the higher rated player), but the game finished in a draw.

Given that both players had perhaps twenty seconds remaining plus the two second increment when queens were exchanges, it is not surprising that both of them missed wins in the pawn ending. I found the errors instructive.

After the tournament, I downloaded this game, set up what I thought was a critical position where Black might have played differently, and proceeded to easily beat Komodo 13. I was less successful playing the queen ending, sustaining a slight advantage with White, but unable to find the win.

White (1386) -- Black (1994) [C01]
Live Chess Chess.com, 26.08.2020

White to move

30.Qxe8+

White exchanged into a lost pawn ending, but Black must play correctly to win.

One of my efforts against Komodo continued: 30.Qxb7 Qa4 31.Qd5 h5 32.Qc5+ Kf7 33.a3 h4 34.Qd5+ Kf8 White is better, but such positions are hard to play on a short increment, and I managed to find ways to lose.

30...Kxe8 31.Kg3 Ke7 32.Kf3 b5 33.Ke4 Ke6

White to move

34.d5+

White's move is technically best, but 34.g4!? presents Black a problem. 34...Kd6 is the only move. For instance, 34...a5 35.d5+ Kd6 36.Kd4 b4 37.Kc4+- and Black is the one in zugzwang.

34...Kd6 35.Kd4

Black to move

35...a5??

Yes, the queenside majority is the decisive advantage in the position. However, the position of the kings makes all the difference. The extra pawn on the queenside must be used to take the White king out of action long enough for Black's king to gobble up pawns on the kingside. See "Fox in the Chicken Coop". Or watch this video on my Facebook page: "Fox in the Chicken Coop".

A little patience reducing White's choices to gain a tempo or two by placing White in zugzwang is necessary to win this ending.

35...f5 would be my instinct, and the computer confirms that this move (or 35...h5) is necessary. My play against Komodo continued 36.Kc3. Why did the computer give up the pawn so easily?

In analysis of my game with the engine, I examined 36.g3 h5 37.f3 a5 38.g4 fxg4 39.fxg4

Black to move
Analysis Diagram

39...h4 is the only move. 40.a3 a4 41.Ke4 b4 and Black will win.

Continuing my game with the engine: 36...Kxd5 37.Kb4 Kc6 38.Kb3 a5 39.Kc3 Kc5.

Black's 35...a5 was not only not the way to win, but it gave White an opportunity.

36.a3??

36.g4! and White is winning. 

Black to move
Analysis Diagram

Black is in zugzwang. For instance, 37...b4 38.Kc4 and White will have the outside passed pawn on the queenside. 37...a4 is met with 38.a3.

Back to the game as played.

Black to move

36...b4??

I also played this position against Komodo: 36...f5 37.Kd3 Kxd5 38.Ke2 b4 39.a4 Ke4 40.Kd2 f4 41.Kc2 f3! 42.gxf3+ Kxf3

36...h5 is the alternative.

37.axb4 axb4 38.Kc4 b3 39.Kxb3 Kxd5 And the game was drawn by repetition after another dozen moves.

Queen versus Knight

Winning with queen versus knight is an elementary skill, but it is easy to falter with the wrong plan. This morning, I struggled briefly with a position that resulted from misplaying a bishop and pawn versus knight ending that I found in Rashid Ziyatdinov, GM-RAM: Essential Grandmaster Knowledge (2000).

White to move

1.Be5

Obvious first move--trap the knight.

1...Ke7 2.Kc5 Kd7 3.Kb5 Ke7 4.Kc6 Kf7

White to move

5.d6 Ke6 6.d7

6.Bd4 would have simplified matters. 6...Nf4 7.d7 Ke7 8.Bc5 and attempting to occupy the promotion square leads to a quick checkmate.

6...Kxe5 7.d8Q Nf4

White to move

I reached this position thinking it would be easier than it was. It became clear that I could use some work on elementary skills.

Elements of the Game of Chess

After several efforts, then engine checking, followed by further practice, I began to see some patterns. I then remembered an old textbook that had some exericises, William Lewis, Elements of the Game of Chess (1822). In "Lesson One" (August 2017), I discussed the merits of Lewis's approach to elementary checkmates with the queen. Queen vs. knight is the next chapter in his book.

Lewis's first position is instructive, and his solution is very close to what chess engines reveal today.

White to move

Lewis
Queen vs. Knight, 1822

1.Qd4+ Ke6 2.Ke4

Black to move 

2...Ng6

Lewis gives the variation 2...Nc6 3.Qd5+.
The engine shows that 2...Nf7 holds out one move longer.

3.Qb6+

Lewis's technique takes one move longer than the engine's top two choices.

3...Kf7 4.Kf5 Ne7+ 5.Kg5 Nd5 6.Qd6 Ne7 7.Qf6+ Ke8 8.Qe6 Kd8 9.Kf6 Nc8

White to move

10.Qc6 Na7

10...Ne7 11.Qd6+

11.Qb6+ 1-0

Lewis treats his readers to two more positions. In both cases, White has a knight-winning fork on the second move.

White to move

My students will be seeing these positions this coming week.

Learn the Ending

As tine was running low on the clocks, I was watching the last two games finish in the second round of a youth tournament. As the tournament director, watching the clocks during a time scramble can be important. In the penultimate game, White offered a draw because he was certain that should be the result. Black wanted to play it out. A few moves later the queens were exchanged and the game was drawn. However, the result could have been different if the player with Black had studied a position that can be found in most endgame books.

White to move

White played 1.a8Q and offered a draw. Play continued 1...Qc6+ and after a few moves the kings were on b5 and b8 and the queens were on b6 and b7. Queens were exchanged.

Mark Dvoretsky, Dvoretsky's Endgame Manual has a similar position.

White to move

1.Qb3+ Ka1 2.Qd1+ Kb2 3.Qd2+

This square is where the queen needs to go. In the game from my tournament, 1...Qd7 was the equivalent move with the same idea.

3...Kb1

3...Ka1 allows 4.Qc1#

4.Kb4

Black's king already occupied the mirror of this square in the youth game.

4...a1Q 5.Kb3

Black to move

Black is in zugzwang with no safe square to move the queen without losing it or allowing checkmate.

The youth game could have continued 1...Qd7+ 2.Kb8 Kb6 and White would be in zugzwang.

Critical Moments

How do you analyze a chess game?

I do several things, but the first step--whether my own game or one played by others--is identifying the critical moments in the game. When did the loser reach a technically lost position?

Today was the last day of my tenth annual youth chess camp. The students spent the week--fifteen hours--solving exercises in a workbook (available on Amazon), playing tournament games, discussing games and parts of games with me and with each other. Throughout the week, I stressed a learning process that extends well beyond the week of camp: work on endgames, then tactics and planning, then openings, then study whole games. When they arrived this morning, I had two positions on the two demo boards. We talked about the endgame first. Then we talked about the middlegame.

Black to move

With two legal moves, Black chose the one that loses.

White to move

White turned an advantage into a lost game by moving the queen to the wrong square.

The whole game with annotations at the critical moments is offered below.

Stripes,J. (1911) -- Internet Opponent (1892) [A43]
Chess.com, 10.08.2017

1.d4 e6 2.c4 c5 3.Nf3 cxd4 4.Nxd4 a6 5.g3 Qc7 6.Qc2 b6 7.Bg2 Bb7 8.e4 Nc6 9.Be3 Nxd4 10.Bxd4 Nf6 11.0–0 Bc5 12.Bxc5 bxc5 13.Nc3 h5 14.Rad1 h4 15.Qe2 hxg3 16.fxg3 Ke7 17.e5 Nh5 18.Ne4 Bxe4 19.Qxe4 Rag8 20.Rd6 f5 21.Qh4+ [21.Qd3] 21...g5 22.Qh3 Nf4 23.Qxh8 Ne2+ 24.Kf2 Rxh8 25.Kxe2 Rxh2 26.Kf2 g4 27.Rfd1 a5 28.Kg1 Rh8 29.b3 Rd8 30.Bc6 dxc6 31.Rxd8 Qxd8 32.Rxd8 Kxd8 33.Kf2 [33.a4 Ke7 34.Kf2 Kf7 35.Ke2 Kg6 36.Kd3 Kg5 37.Ke3 f4+ 38.gxf4+ Kf5 39.Kf2] 33...Kc7 34.Ke3 Kb6 35.Kf4 a4 36.Ke3 Ka5 37.bxa4 Kxa4 38.Kf4 Ka3 39.Kg5 Kb4 40.Kf6 Kxc4 [40...f4 41.gxf4 g3] 41.Kxe6 Kd4 42.Kxf5 c4 43.e6 c3 44.e7 c2 45.e8Q c1Q 46.Qd7+ [46.Qe4+ Kc5] 46...Ke3 47.Qe6+ Kf3 48.Qe4+ Kxg3 [48...Kf2 49.Qf4+ Qxf4+ 50.Kxf4 c5] 49.Qxg4+ Kf2 50.Qf4+ Qxf4+ 51.Kxf4 Ke2 52.Ke4 Kd2 53.a4 Kc3 54.a5 Kb4 55.a6 c5 56.a7 c4 57.a8Q c3 58.Kd3 c2 59.Kxc2 1–0

After these two positions, we looked at Fischer -- Stein 1967, which they have in their book. Following that presentation, the students worked in groups studying other great games. Then, they played the last round of their tournament. During the last fifteen minutes, we went through the whole game from which I had extracted the two positions that we began with nearly three hours earlier.

Decisive Advantage?

When do you resign? Losing an exchange should not be sufficient cause for resignation. But, what if you are down an exchange and your opponent is rated 300 Elo higher? What if you are down an exchange and your position is passive?

Going through the games in Branko Tadic and Goran Arsovic, Encyclopedia of Chess Miniatures (2015), I came across a game where it seemed that Black might have resigned a little early. It did seem as though White's play from the position at the end of the game was relatively straightforward and that Black was consigned to passive defense. Even so, most players would play on in such a position.

I searched for the game online and found that 2700chess.com has it. That site offered me the option of playing against the computer from the final position. Of course, I could easily set up the game on my computer and play Stockfish 7, but it was coffee time. While drinking my coffee, I like to sit in the living room with my dogs and use my iPad. The strongest chess engine setting that seemed available to me on the website was 2200--good enough that it will exploit tactical blunders or force a draw if the opportunity arises.

Komarov,Dimitri (2541) -- Bogdanov,Emil (2249) [E12]
FRA-chT N1 Drancy (3), 06.02.2005

1.d4 Nf6 2.Nf3 e6 3.c4 b6 4.a3 Bb7 5.Nc3 Be7 6.d5 0–0 7.g3 d6 8.Bg2 Re8 9.0–0 Bf8 10.b4 c6 11.Nd4 cxd5 12.cxd5 Nxd5 13.Nxd5 Bxd5 14.Nxe6 fxe6 15.Bxd5 Nd7 16.Bxa8 Qxa8 17.Bb2 Be7 18.Rc1 1-0

Black to move

After playing against the computer, my coffee was finished. I went to my computer, entered the moves into a database, and ran quick analysis with Stockfish 7 at full strength to observe what I or the weakened engine on 2700chess.com might have missed.

Stripes,J -- Stockfish (2200 strength)
2700chess.com

18...b5 19.Qb3 Bf6 20.Rc7

Stockfish seems to prefer that I play Rc7 before Qb3. 19.Qd3 was also an option. All of these moves offer white an advantage of 2.5+, a little more than the material difference.

20...Ne5 21.Bxe5

I did not want this knight plugging the c-file.

21...Bxe5 22.Qe3 Qd5 23.Qxa7 Bb2

White to move

One improvement Stockfish 7 noted up to this point was that I might have played Rfc1 on any of several moves. Now, Black prevents bringing the second rook to the open file.

24.Qb7

Is it beneficial to exchange queens when ahead a rook for a bishop, and with more active rooks? I thought so here.

24...Qe5 25.Re7

At first, Stockfish prefers 25.e3, but as it examines the position longer, it likes my move almost as much as its first choice.

25...Rxe7 26.Qxe7

Threatening checkmate in one.

26...h6

26...h5 might be a little better.

27.Rb1

This move drops the computer's assessment of White's advantage from near 5.0 to 3.5. Even so, it seems that I have improved White's advantage from the end of Komarov -- Bogdanov.

Stockfish likes 27.Qe8+ Kh7 28.a4.

I did not look at this variation during the game. The central Black pawns had been my focus when considering why Bogdanov resigned.

27...Qxe2 28.Qxd6 Kh7

White to move

29.Rxb2!?

The point of my move 27. Giving back the exchange to enter a queen ending with only a one pawn advantage would normally seem the way to convert a win into a draw.

29...Qxb2 30.Qd3+ Kh8 31.h4?!

I had originally planned 31.Qxb5 Qb1+ 32.Kg2 Qe4+ but was not prepared to play 33.f3 Qc2+ 34.Kh3. This unplayed line is Stockfish 7's preference.

31...Qe5

White to move

My advantage has diminished to 1.27, but my confidence is now rooted in the observation that Black's queen can defend both e6 and b5 from relatively few squares.

32.Kg2 Kg8 33.Qf3 g6

Stockfish 7 sees this move as half a pawn worse than 33...g5. Was 33...g6 Black's critical error? It seems to me that I now have a third pawn for my queen to attack. How can Black defend everything?

34.Qb7 Qe2 35.Qb8+ Kg7 36.Qc7+ Kh8

White to move

37.Qd8+

37.Qf7 seems faster.

37...Kg7 38.Qe7+ Kg8 39.Qf6

Black to move

39...h5

39...Qe4+ at first seems to refute my plan to convert a queen ending 40.Kh2

a) 40...Qf5 41.Qxf5 exf5 42.Kg2 should be a simple win for White
b) 40...Qc2 41.Qxe6+ Kg7 42.Kg2 increases White's advantage to two pawns and weaknesses remain in the Black position.

40.Qxg6+ Kh8 41.Qf6+ Kh7 42.Qf3 Qe5 43.Qe3 Qd6

43...Qd5+ 44.f3 Qa2+ 45.Kh3 Qa1 complicates my task.

44.Qe4+

Black to move

44...Kh6

44...Kg7 45.Qb7+ Kf6 46.Qxb5 and now three pawns to the good for White.

45.Qf4+ Qxf4 46.gxf4

Black to move

The rest is simple.

46...Kh7 47.Kf3 Kg6 48.Ke4 Kf6 49.f3+-

Checkmate was delivered on move 69.

Playing by Intuition

Yesterday, I was showing an ending from a blitz game to an adult student. As he does not play blitz, he seemed skeptical of the value of understanding errors that were made because they were played without thought.

It was a challenging teaching moment for me. In blitz, play is by intuition most of the time. How important is this intuition when there is plenty of time on the clock?

We backed the game up to the beginning of the endgame, when I forced queens off the board to go into an pawn ending that I considered comfortable.

Black to move

I played 37...Qg6+ after six seconds thought. For the rest of the game both players moved in one and zero seconds every move, suggesting that we were racing the clock more than playing the board. Nonetheless, during my postgame analysis, I sought to extract the truth of the position as preparation for the lesson with my student.

He wanted to know what I would have thought about if I had fifteen minutes.

Black's pawn structure is worse, I said. With queens on the board, both players are playing for three results: win, draw, or loss. Exchanging queens, I said, reduces the possibilities to two. I am playing for a win or a draw.

However, that explanation assumes correct play. In fact, with correct play this game should be drawn with or without queens. Exchanging queens eliminates the isolated pawn, as was my intent. Even so, both players have three results possible. It is a draw with correct play and a win for one player if the other blunders.

As it happens, I blundered.

38.Qxg6 hxg6 39.Kf3 Ke7 40.Ke4 Ke6 41.g4

Black to move

White's last move restrains Black from playing 41...f5?? Yet, that is exactly the move that I played.

This error gives White an outside passed pawn on the h-file. Black's king is forced to contend with the h-pawn, permitting the White king time to mop up the other pawns. See "Outside Passed Pawn" and "Fox in the Chicken Coop".

Even so, it is not as simple as racing over to the a-file thanks to Black's pawn majority in the center.

Later, my opponent erred by pushing the h-pawn prematurely. My blunder was the second to the last error, and it was the last error that decided the game.

With enough time to think, I would not have played 41...f5. Likewise, my opponent would have held back the h-pawn if not for his or her time pressure.

Today in a rapid game, I played instantly in a position that required a simple counting exercise. Counting might have taken five seconds, but I moved instantly (see "Panic Mode"). My memory or my intuition gave me the result of counting without expending the five seconds to verify. I could have invested the five seconds with ninety seconds remaining on the clock, plus a small increment that can add time.

White to move

It is helpful to be working with a skeptical adult student who wants to learn endgames. He will distrust my intuitive blitzing mode and ask how I calculate.

How do I know that White's h-pawn will promote before Black's a-pawn?

54. Rxg5?? leads to a position where both players have the same number of pawns and neither player can hope for more than a draw. That's why I played 54.Rxc7+ and went on to win the game after a successful pawn race.

If the rook exchange took place on c6, instead of c7, the Black king gets White's a-pawn one move faster. Even then, however, White's queen covers the promotion square and the Black king is too far beyond its pawn.

It seems to me that counting is not the only element of knowledge of rook endgames and pawn endgames that guided my intuition here. There are many pawn races where pawns promote in opposite corners. In the dramatic denouement of the film Searching for Bobby Fisher (1993), Josh Waitzkin's opponent promoted first. However, his king stood on the long diagonal. Josh promoted his pawn with check and skewered the king to win the queen.

My memory of the ending of this movie was not conscious during the game. Did it contribute to informing my intuition?
