Think Like a Super-GM

I watched an excessively long video on YouTube concerning the best puzzle books. Nonetheless, the long discussion was often interesting. Most of the books highlighted are useful for masters, but less likely to benefit lower rated players. But there were some, such as the Polgar brick, that also earned accolades.

One of the top choices has proven difficult for strong players, but has improved their game. It reminded me of Jeremy Silman, The Amateur’s Mind because the thoughts of players at different levels were recorded, presented, and evaluated.

That book is Michael Adams, and Philip Hurtado, Think Like a Super-GM (2022). I ordered it Thursday morning, it arrived Thursday evening, and I took it with me on a weekend trip to Montana. I did the first exercise while eating breakfast.


I found the key move, but my analysis needs to go deeper to reach a correct evaluation.

Tactics Training

These days, it seems that I spend more time doing puzzles online (chessdotcom mostly, but also Lichess and Chess Tempo) than working with positions in books. Still, for serious improvement in tactical vision and calculation, books are superior.

After racing through Thomas Engqvist, 300 Most Important Chess Positions (2018) in less than three months, I’m more highly motivated to keep 300 Most Important Tactical Chess Positions (2020) near the center of my chess activities through the rest of 2025. Four of the first five positions in the book have forcing continuations that run deep enough that I anticipate some challenge working through the book. Difficulty makes the enterprise worthwhile.

Today’s position arose in Mason,J.—Winawer,S., Vienna 1882. Engqvist’s analysis is instructive. At least three problems for players at different levels can be extracted from Mason’s combination.

Engqvist's position is before Mason's 40.Rxg5 (see photograph). If Black refuses the rook sacrifice, 40...Qf8 41.Rg6 controls the sixth rank. Then, 41...Rxf5

White to move
42.Qxf5! Qxf5 43.Rg7+ Nd7 44.Rxd7+ Kc8 45.Rxb8+ (only move) 45...Kxb8 46.Rb7+ and whichever way Black's king steps, Black's queen is coming off the board and White has a winning endgame.

After the line played in the game (40.Rxg5 hxg5 41.Qh7+ Nd7 42.Bxd7 Qg8--this position appeared as a exercise on chessgames.com in 2003--43.Rb7+ Kxb7), there is a more basic exercise position.

White to move
The discovery (44.Bc8+) is Engqvist's theme for this exercise, and the interference is an important aspect of why it works. Posters on chessgames.com and Engqvist valorize Mason's technique bringing home the full point for the resulting ending of queen and bishop vs. two rooks.

The Superiority of Books


For beginning students, the sequencing in such books as Sergey Ivashchenko, Manual of Chess Combinations (1997) and Susan Polgar, A World Champion’s Guide to Chess (2015) will lead to much more rapid growth in tactics skill than random positions online. Of course, with certain membership levels, chessdotcom and Chess Tempo allow training with particular themes and rating levels, so these can be tweaked with appropriate guidance.

For players who know basic patterns, but need work on strengthening calculation skills and assessing resulting positions after a combination, such books as Mark Dvoretsky, Secrets of Chess Tactics (1992), Paata Gaprindashvili, Imagination in Chess (2004), and Cyrus Lakdawala, Tactical Training (2021) offer abundant exercises.

Yakov Nieshtadt, Improve Your Chess Tactics (2012) is highly regarded for its organizational scheme and definitions, while Yuri Averbakh, Chess Tactics for Advanced Players (1992) articulates a notion of contacts that should be more common in chess literature.

Tactics Binge

This morning I became obsessed with solving puzzles on chess.com. For some of them, I spent a few minutes calculating. For others, I moved almost instantly, believing the puzzle was simple pattern recognition. Errors were frequent. When I failed a puzzle, I tried again, working it until I found the answer. One puzzle was ridiculously easy. As it came after failing four of the previous five, I had the sense that the site’s programming is designed to poke fun at me.

White to move
At this point, I had solved six correctly and failed eight. My tactics rating had dropped 35 points.

As the session continued, my rating kept going down, then up a bit, then down again.
When I finally quit, I had attempted 169 puzzles. My rating rose three points from 3036 to 3039. At one point, I had dropped as low as 2939.

Puzzles

On 19 December 2022, I noted on Chess Skills’s Facebook page that I was considering a push through 266 more puzzles to reach a milestone: 5000 puzzles solved on chess.com by the end of 2022. I did far more, completing 649 puzzles in two weeks.

My puzzle rating on 19 December was 2806 with a peak rating of 2849. My puzzle rating at the end of the year was 2855 with a peak of 3002. I crossed over 3002 early Christmas morning, but became greedy in an effort to surpass a friend who was at 3012. An hour later I had fallen to 2702 (see “Blitz Addiction”). I got back to 2802 before I quit. through the last week of the year, I labored to keep my puzzle rating over 2800.

These are the last three that I failed in my final session on New Year's Eve.



Puzzles on chess.com can be instructive. They can be rewarding. In the last two weeks of 2022, I found them addicting.

Often I find more benefit in puzzles from books. The sequencing of puzzles in The Manual of Chess Combinations by Sergey Ivashchenko provide instructive value that is missing from all online tactics training. I could benefit from working through volume 2, which is at the right level for my current skill. Like the exercises that chess.com feeds me, I should get most of them correct when I am focused. Volume 1 is easier, but I made a personal commitment to do all the more than 1300 exercises in one year's time. I started at the end of February and have about 500 more to go.

The difficulty of the puzzles in Paata Gaprindashvili, Imagination in Chess: How to Think Creatively and Avoid Foolish Mistakes (see my review, “Imagination in Chess”) keep calling me. They offer no instant rewards with a meaningless online rating, but instead offer deeper satisfaction when I solve them correctly. These puzzles are on par with volume 3 of The Manual of Chess Combinations by Alexander Mazja.

Comic Error

There are a few errors on the ChessBase DVD that I mentioned in "Building a Lesson", Master Class 4: Jose Raul Capablanca. The one I found this morning is comic in the light of Capablanca's discursive comment at that point of the game. This position arose in the fifth match game between Frank Marshall and Jose R. Capablanca, 1909.

Black to move

Capablanca annotated this game in My Chess Career (1920). Capablanca played 26...Rxd4, and in his annotations indicated that he could have saved himself a lot of trouble by playing 26...Qf6. ChessBase omits this annotation, but after the subsequent 27.Qb8+ offers 27.Qc3 as an improvement. In fact, after 27.Qc3, Black checkmates in two moves.

In descriptive notation, both Capablanca's improvement and ChessBase's blunder are written Q-B3.

Capablanca comment on his own inaccuracy is instructive regarding ChessBase's error, and my own presumptions to comment on these games.
Not the best, Q-B3 was the right move. Incidentally it would have saved me a great deal of trouble which I had to win the game. Here I will call attention to the poor notes sometimes written by analysts. Games are often annotated by unknown players who have not sufficient knowledge of the game. As a matter of fact, the games of the great masters, at least, can only be properly annotated by very few players. Of course even the best are not exempt from mistakes, but while they make them few and far between the others do so continuously. (31)
I found another, slightly less severe, error earlier in the game as well. In that case a move was omitted from the sequence of exchanges, but this omission leads to an entirely different result--a Marshall win. Capablanca's annotation on his 26th move continued into a second paragraph.
I was highly praised by many because of the excellence of my play in this position, while in reality I could have done better. They simply did not see that here Q-B3 was better than the text move. (31)
White's 27.Q-B3 certainly would have been a lot better for Black. Marshall could have resigned at once.

Five Days to Better Chess

Five Days to Better Chess: Essential Tools was published a few days ago. What is this book about? Who is the audience?

This book offers content and process. This process is for all chess enthusiasts who seek to improve their own game, or who help others to do so. The content aims principally at developing players up to average club strength (Elo 1400-1600). Will it lift you to this level in five days? No. It was noted by a critic on Facebook that a title like "five days to..." cheapens content by promising what no book can deliver. Maybe I could have called it "five steps ..." instead? Better is not best. Improvement is a journey; this book offers a map.

The process mapped in Five Days to Better Chess is neither original nor the norm in chess training. The process is rooted in the experience of watching players of all levels fail to demonstrate basic skills. This process begins at the end of the game and works from there towards the beginning. That is, it starts with checkmate. First, there are elementary checkmates with a few pieces against a lone king. Chess Fundamentals (1921) by Jose R. Capablanca begins the same way. From elementary checkmates, Capablanca moves to simple pawn endings, then middlegame positions, and finally general opening principles. He then repeats the sequence from endings, through middlegames to openings. In Chess Fundamentals, this sequence repeats a third time, then the book contains illustrative games.

Five Days to Better Chess advocates this repeating process, but the book is structured in five units: checkmates, endings, middlegames, openings, and great games. The first four units each begin with relatively elementary skills and build towards more complex. The plan is for readers to read part of each unit and then go through the book again, reading other parts.

The beginning of the checkmate unit illuminates this structure:
How do you become better at checkmate? Skill at execution of checkmate is your tool box for finishing the game. Your tools are 1) mastery of elementary checkmates with heavy pieces, 2) experience with minor piece checkmates, 3) recognition of common checkmate patterns, and 4) calculation skill.
Among the patterns are a list of 37 checkmate configurations, a section on the varieties of corridor checkmates, some work on the weakness of f7/f2 designed to steer players away from attempting scholar's checkmate. Legall's pseudo-sacrifice is offered as a better effort to trap the unwary. Finally, there is a section on the classic bishop sacrifice (Bxh7+) that highlights defensive resources.

Several instructive portions in each of the first three units offer a small number of exercises. Each of the first three also have forty exercises that conclude the unit. For strong class players (above 1600), these 120 exercises could offer a quick warm-up before tackling tougher problems. For those under 1400, they may prove challenging. The exercises offer a range from quick and easy, and thus within reach of those new to the game, to a few with instructive nuances that cause stronger players to pause and calculate.

When I was studying Byrne -- Fischer 1956--the "Game of the Century"--a few months ago, I had this position on the dining room table all weekend.

White to move

Without moving any pieces, I tried to calculate and record the principle variations. I became caught up in long and difficult assessment of variations that follow after 18.Bxe6, which was not played in the game. The obvious answer finally hit me while folding my laundry. The position after 18.Bxe6 is on the book's cover and is Checkmate Challenge #70 at the end of the checkmate unit. The notes that I produced that weekend also appear in the fifth unit, devoted to great games.

After checkmate, the process advocated in Five Days to Better Chess presents endgames as day two. It begins with elementary king and pawn positions that highlight the square of the pawn, breakthrough ideas, and the fundamentals of opposition and outflanking. There are sections on knight vs. bishop, queen vs. pawn, and queen vs. rook. A large chunk on endings presents the most important rook endings, concluding with two examples of Vasily Smyslov's exemplary defense against a rook and two pawns with a rook (pawns on the f- and h-files). All of these topics are treated in much greater detail in books by Yuri Averbakh, Jeremy Silman, Mark Dvoretsky, and others. Nonetheless, my explanations may prove useful to many students and coaches. Five Days highlights those skills that are most fundamental.

A section of the middlegame unit offers an extended discussion of the many aspects of pins. Then a short glossary defines with examples the other thirteen most common tactical ideas from attraction (decoy) to zwischenzug. A section on strategy builds upon Dan Heisman's Elements of Positional Evaluation (1999) through deep analysis of the key moments in Pillsbury -- Lasker 1896.* Lasker's own presentation of this game in Lasker's Manual of Chess (1947) validates the usefulness of Heisman's seven elements. Annotations to a couple of Paul Morphy's games further develop the reader's understanding of positional play.

The opening section develops basic principles, and then returns to Lasker's critique of his loss of time against Pillsbury, then offers move-by-move discussion of one line of the classical French (the opening in that game). Four more openings are presented, highlighting verbal explanations of basic principles--Italian, Spanish, Queen's Gambit, and London System. These are tied to model games, including a thrashing of Pavel Eljanov's Catalan by Magnus Carlsen. The exercises at the end of the chapter are twelve instructive miniatures for readers to analyze. Solutions in the back of the book highlight the key errors.

The chapter on great games offers a narrative of my quest for the best game ever played and annotations of three masterpieces that just missed the top ten. The annotations highlight my own learning process as a model for readers, including an extended discussion of how Vladimir Barsky, The Ragozin Complex (2011) helps elucidate strategies Jon Ludvig Hammer employed in his masterpiece last year in Stockholm. My ten candidates for best game are presented in full for reader analysis. Five Days offers brief statements of the merits that I see in each game. The focus in this unit is offering suggestions on how students of the game might approach learning from such games, especially how these games teach all elements from the opening to the endgame.

Two Notes

The subtitle, essential tools, employs a metaphor. Those are my tools on the cover. The metaphor comes out in the writing.


Regular readers of Chess Skills already know that I am a historian. This book offers many anecdotes and vignettes of chess history, such as the origin of the word pawn.

Genesis of the Work

Five Days to Better Chess is the culmination of more than ten years' work. In summer 2008, I offered my first chess camp for children at the school where I had been coaching eight years. My work as a youth  chess coach began as a parent volunteer at my son's school. When he moved on to another school, I was offered a stipend so that I would stay on as the coach.

Offering a chess camp extended the chess work one week into the summer, while also intensifying the learning opportunities. To keep the children focused, I prepared more exercises than they could possibly finish even if that is all they did during camp. Camp included competition--a pawn wars tournament, checkmate contests, a camp tournament with one game per day--lectures, and solving sessions. Camp points  accumulated as long as behavior was good and exercises were completed. Bonus points were awarded to those who won games, and to those who practiced chess notation.

Assembling the exercises and some of the instructional material into a workbook gave the students something they could take home. My hope was that they would study on their own through the summer. The school photocopied my materials, and then I had them spiral bound with card stock covers at Kinkos or Staples.

I used the same workbook the second summer, changing only the date on the cover. The third year, I created a new workbook focused on learning from Adolf Anderssen, titling it "Attacking with Anderssen". Tactics exercises came from his games. I recycled some of the materials, especially the elementary pawn endings. As the theme changed year after year, some materials that I recycle were fine-tuned. These appear in Five Days to Better Chess.

When I published Forcing Checkmate through Amazon this spring, I learned that Amazon's printing cost and mark-up was barely more than I paid at Staples for spiral binding. It seemed time to expand my workbook and get professional binding. I aimed for 200 pages because that was the minimum length that would allow printing the title on the book's spine. I ended up with more than 225 double-column pages of content, plus front matter and a couple of blank pages to facilitate design elements.



*The second edition of Heisman's book was published in 1999. I have the fourth edition as well.

The Polgar Brick: eBook Edition

A Review

Chess: 5334 Problems, Combinations, and Games by László Polgár contains 306 checkmate in one, 3412 checkmate in two, 744 checkmate in three, and then 600 miniature studies. These miniatures (game of 25 moves or less) are sorted into six groups. Each group contains 100 games that featured a sacrifice on one of a pair of squares--f3.f6, g3/g6, h3/h6, f2/f7, g2/g7, and h2/h7. I described one of the ways that I found this section useful in "Building Upon Morphy". Following the miniatures section are 144 simple endgames and then 128 combinations from the Polgár sisters, Susan, Sophia, and Judit. Susan and Judit are Grand Masters, and Judit was in the FIDE top ten a few years ago. Sophia, who was more interested in art than chess, is an International Master.

The book was first published by Könemann in 1994 under the title Chess in 5333+1 Positions. The "+1" in the original title reflects the distinctiveness of the final position, an artistic checkmate in two composition by Sophia. In 2006, Black Dog & Leventhal brought out a new edition that is approximately half the size--same thickness, but 6 x 9 inches instead of the large 8 x 12 format. I have the Könemann paperback edition, which I bought for $25 in 1998. The smaller edition is still a large book, although considerably lighter than the original. At some point, this book acquired the nickname "Polgár Brick" in several social media forums. Both editions are 1104 pages.

The Black Dog & Leventhal edition added an introduction by Bruce Pandolfini, while eliminating front matter in languages other than English. The Könemann edition has the table of contents, Polgár's forward, and other material in ten languages.

It is a useful book for self-study and useful to chess teachers, but it is awkward to carry in a backpack. Last week, I bought the Kindle eBook edition for $2.99 and now have the book on my iPhone and iPad. Hence, I always have it with me unless I am swimming.

Fifteen years ago, I spent 20-30 minutes per day with this large book during my morning coffee. I would solve each exercise looking at the diagram and write down my answer on a piece of paper. Then, I would check the answers in the back of the book and record the percentage that I got correct. When this percentage was below 90, I would rework the problems a few days later. Over the course of a few months, I solved the first 1596 problems. Since then, the book has mostly sat on a bookshelf alongside other neglected books. Occasionally, I would pull it off the shelf when looking for some instructive checkmate exercises for students or to work through some of the book's miniatures.

Even strong players capable of solving difficult tactics problems could benefit from working through the checkmate in one exercises. The first 156 contain a minimum number of pieces. Beginning with number 157, the board is crowded with pieces. How many can you solve as fast as you turn the page? I found that I could solve the first 156 instantly, but then slowed down. Some took a few seconds; others were as easy as those with few pieces. Solving these exercises quickly and repeatedly should improve board vision and pattern recognition.

Some of the ckeckmate in two exercises are challenging, depending on your skill level. But, they are intended by Polgár to require only a few minutes and to build the reader's confidence. Naturally, the checkmate in three are more challenging, but still not horrendously difficult.

In the print edition, there are six problems per page. The eBook presents one per page. In the solutions, the composer is indicated if is was not Polgár. For the checkmate in one (naturally) and the checkmate in two, only one move is given. The solutions to the checkmate in three are carried out to checkmate. In the eBook, the problem number is a hyperlink to the solution and the number above the solution links back to the problem.

Only a few of the first 4462 positions are from real games. The 600 miniatures, of course, are all real games, as are 127 of the 128 from the Polgár sisters.

The eBook edition extends the usefulness of this book. It is certainly much easier to carry, as noted above. There are a few formatting issues, but these serve only as distractions and do not mar the book's usefulness. Some of the solutions seem to be in a larger font, for example. In the bibliography at the end of the book, the Russian language sources listed are in a smaller font than the other texts.

Now that I have the eBook, I expect to make much more extensive use of the miniatures section. Last fall, I carried the mammoth book to a chess lesson with a student so that we could look at a few of the miniatures together. Then, it sat on the floor of my car for most of the winter. No longer. The book need not leave my house, and I will always have it during chess lessons. I rarely do not have my iPad and never leave my home without my phone.

Print Edition First Miniature
In the book, the miniatures contain the early moved of the game, then a diagram with the critical position. Underneath the diagram is the conclusion of the game. This is the same structure that one finds in the Encyclopedia of Chess Miniatures (2015). Ideally, the student would look at the diagram and solve the position without looking at the continuation below. This exercise is most easily accomplished by covering the moves below with a scrap of paper.






eBook Edition First Miniature
In the eBook edition, the initial moves and diagram are on one page, and the game's conclusion is on the next page. That structure makes it more useful as a training tool than the print edition and the cost is slightly more than 10% of the publisher's list price.

If you do not have this book, it might be time to download the free Kindle app and enter the world of chess eBooks. There are many exceptional chess books in this format. Few are as good of a bargain as the Polgár brick. Do be careful, however, there are chess eBooks that are complete rubbish. Some are even written by people who do not know how to play chess (see "Kindle Chess Books").

One from Greco

The oldest English language book that presents games from Gioachino Greco (c.1600 - c. 1634) is Francis Beale, The Royall Art of Chesse-Play (London 1656). This book contains 94 games attributed to Greco, as well as examples of Fool's Mate and Scholar's mate. This number of 94 exceeds the 77 Greco games that one can find in databases and at sites such as chessgames.com because the variations were reduced to those Angelo Lewis considered the main games. Angelo Lewis (1839-1919) wrote under the pseudonym Professor Louis Hoffman. His The Games of Greco (London 1900) is the basis for those found in David Levy, and Kevin O'Connell, Oxford Encyclopedia of Chess Games, vol. 1, 1485-1866 (Oxford 1981), which in turn became the source when databases were created.

In between Beale and Hoffman, William Lewis (1787-1870) produced an edition of Greco's games, Gioachino Greco on the Games of Chess (London 1819), which was based on a French edition of Greco's games. In Lewis, Greco's games are 168 variations of 47 games.

In Beale's book, the games are called "Gambetts" and numbered with roman numerals. The first game in the book is also in Hoffman and the Oxford Encyclopedia, but the final move differs.


Gambett I (Greco) [C23]
Beale 1656

1.e4 e5 2.Bc4 Bc5 3.Qe2 Qe7 4.f4 Bxg1 5.Rxg1 exf4 6.d4 Qh4+ 7.g3 fxg3 8.Rxg3 Nf6 9.Nc3 Nh5 10.Bxf7+ Kxf7 

White to move

11.Bg5 Nxg3 12.Qf3+ Kg6 13.Bxh4 Nh5 14.Qf5+ Kh6 15.Bg5#

15.Qg5# is given in ChessBase per Hoffman; Levy, and O'Connell; and Lewis.

1–0

This game is in Lewis 1819, 70; Hoffman 1900, 110; Levy, and O'Connell 1981, 4; and Beal 1656, 18-19.

My eBook, Essential Tactics: Building a Foundation for Chess Skill (2017), contains a composed position that I derived from the diagram position above.

White to move

My method in creating that book was to take positions from actual games and typical structures that might occur in games, and then strip away the extraneous pieces. I made such modifications necessary that in most cases there is one clearly best move, and often only one winning move (or drawing move in certain cases).

How Easy?

I created this exercise four years ago for my students. It is one of what I call "one-move worksheets". I create a single page of four to nine exercises that I am able to photocopy for my chess students. I have made some of these worksheets available to other coaches.* Some have been collected and gathered into two books that I self-published through Amazon. Essential Tactics consists of 150 exercises with ten pieces or fewer. Forcing Checkmate contains 160 exercises leading to checkmate.

This position is number 82 in Essential Tactics. Every time I look at it, I worry that White cannot win, but that it should be drawn. Some of my exercises do lead to draws, but not this one.

White to move

This morning, I played the position out against Stockfish and checkmated the silicon beast in 29 moves. I think that I might have won a couple of moves faster if I had calculated a little better. One imprecise move was immediately obvious to me after I made it in haste.

Kindle Chess Books

"The Good, the Bad, the Ugly"

I do not have a Kindle. While at Best Buy, I looked at them, even playing a game of chess with one in the store. It was an easy win. That was in 2010. My wife and I had gone to Best Buy with thoughts of maybe buying Kindles, but went home with two iPads instead. The iPad screen is much larger and Apple offers a Kindle Reader on the App Store.

A couple of weeks later, on a flight to London, I finished reading Zero History (2010) by William Gibson. It was my first Kindle Book. After returning home, I added several more, including the second edition of Mark Dvoretsky, Dvoretsky's Endgame Manual (2008). Adding a copy of this book to my iPad considerably lightened the weight of my chess bag. For most of the previous year, the print version of the first edition of Dvoretsky's Endgame Manual was nearly always with me. In both my chess coaching and personal study away from home, I made frequent use of my pawn ending flashcards (see "Pawn Endings Flash Cards"). It was often helpful to refer to Dvoretsky's analysis.

some light reading
With a lightened chess bag, I increased the number of books that I carried. I added PDF copies of my own self-published pamphlets--"A Checklist of Checkmates" and a couple of camp workbooks. For a few dollars more, the print edition of Gibson's novel would have been easier to read and never face the prospects of a dead battery. But having a growing collection of chess books always in my bag added useful tools to chess study and teaching. I began to see chess e-books as the bee's knees!

Kindle Books are not the only e-books. Google has been creating digitized copies of many old and often rare books. These are available in several formats, including one that can be read in Google Play (Google's answer to the Kindle). The works of William Lewis (1787-1870) have become accessible. Over the course of several months, I translated Lewis's long English descriptive notation in Gioachino Greco on the Game of Chess (1819) into algebraic (see "Gioachino Greco on the Game of Chess"). That expanded my database of Greco's games from the 77 generally available to 168. This expanded database became a core resource for that summer's chess camp and workbook, "Learning from the First Chess Masters."

Unfortunately, the hard drive on my notebook crashed that summer and I had failed to back-up my Greco database. I still have Lewis's book in Google Play, of course. I also have the smaller database created for camp, but most of my work on Greco those two months must begin anew. I have been working with Francis Beale, The Royal Game of Chesse-Play (1656) to rebuild this work. The notation is more difficult than Lewis's. My long-term plan is to have a compendium of the Beale, Lewis, and "Hoffman" (1900) editions of Greco's games. Professor Hoffman (a pseudonym for Angelo Lewis) is the author of the work that forms the basis of the database, but even this work has variations that were left out when the database was created (see "A Greco Miniature").

My collection of seventeenth, eighteenth, and nineteenth century chess books and magazines would fill a bookcase, but they are always with me on my iPad and iPhone. Moreover, they were free. Kindle Books are not free, but they usually cost less than the print edition.

Dan Heisman, Elements of Positional Evaluation, 3rd. ed. (1999) transformed my thinking. In place of Larry Evans' "four elements"--pawn structure, force, space, and time--I have Heisman's seven. Heisman argues against what he calls pseudo-elements--material, space, king-safety, and development. Instead, in a book that reads well alongside John Watson, Secrets of Modern Chess Strategy (1998), he offers mobility, flexibility, vulnerability, center control, piece coordination, time, and speed. It is hard to stop using the word development, but it is much easier to explain what is meant by this vague notion with terms like mobility, flexibility, and vulnerability. Get your pieces to squares where they have maximum mobility and flexibility. Reduce your own vulnerabilities, while looking for ways to exploit those your opponent fails to reduce. Reading the old masters in the light of Heisman's book, it becomes clear that they employed the word mobility to define what they meant by development. They also determined material value by examining how many squares a piece could reach and noting the colors of these squares. See "Principle of Development: Early History" for extended musings on this topic.

The third edition of Heisman's Elements of Position Evaluation contains a minimum of diagrams and few illustrative example. The fourth edition greatly expands the work with many well-illustrated examples. I have the fourth edition in my Kindle library. Other Kindle editions that are always with me and frequently prove useful in my work with youth players include: Bruce Alberston, Chess Mazes (2004); Alexander Alekhine, Alexander Alekhine's Best Games (1996)--a reduced selection from his three volumes with additional notes by John Nunn;  Ray Cheng, Practical Chess Exercises (2007); and now my own Essential Tactics: Building a Foundation for Chess Skill (2017). There are also many books that I use for self-study, especially Alex Yermolinsky, The Road to Chess Improvement (2012), and Garry Kasparov on Garry Kasparov, Part I: 1973-1985 (2011).

Horrors of Self-Publishing

Converting my worksheets with 150 elementary tactics problems into Kindle book format with diagrams featuring colored arrows to highlight the solutions was a year's work. I started in spring 2016, working a few hours per week. The first step was restoring the database used to create the worksheets, because that, too, was lost in the hard-drive crash a few years ago. Then, I started creating colored diagrams as exercises and another set with arrows as solutions. While creating these diagrams, I also wrote the text. After two months of steady work, I set it aside. My body can handle only so much meticulous work in front of a screen. In late winter 2017, I resumed the project with the determination to finish.

Once the manuscript was completed and I had proofread it a few times, publishing was a snap (see "Writing and Publishing"). Only when it was "live" in the Kindle store was I able to see errors that I had missed while proofreading. Over the course of 48 hours, I uploaded five or six corrected editions. I found that it was almost too easy to self-publish a Kindle book.

The first two days that it was available, Essential Tactics sold six copies. That lifted it to #7 among the Kindle chess best-sellers. I started paying more attention to the other top selling Kindle chess books. These lists are updated hourly. Some very good books by strong Grandmasters with a penchant for explaining things clearly are usually on the list. John Nunn, Understanding Chess Move by Move (2013), for example, is in the top ten at this hour. Books about Bobby Fischer, such as Brady's biography, are often near the top. So is Bobby Fischer Teaches Chess, which Fischer did not write.

Also among the top selling chess e-books are instructive manuals by writers no one has ever seen at a chess tournament. A book titled, Chess: Become a Master (2017) aims to lift beginners to the next level. It explains the rules and offers some basic strategy and tactics instruction. The author is not a chess player. The explanations of the rules are full of errors, repeating some of the misconceptions your uncle may have taught you fifty years ago. The strategy and tactics suggestions will make you a worse chess player if you are already over 1000 Elo.

There are similar horrors as bad or worse.

Earlier this week, five of the top ten were a book, The Chess Strategy, by five different authors. All five were the same text: Edward Lasker, Chess Strategy (1915), which is available free from Project Gutenberg. Someone had uploaded this book several times with different covers and fake author names. I wrote a review of one copy identifying the work as plagiarism. Once I received notice that the review posted, I looked at the top selling books again. Ten of the top twenty were Chess Fundamentals, but Jose R. Capablanca was not identified as the author of any of these. Prices ranged from $3.00 to $4.00. This time, however, there was no free Kindle sample, no preview. However, the book description started in mid-sentence and was instantly recognizable to anyone who has spent as much time reading Capablanca's original as I have.

Is it any wonder that I have difficulty attracting potential readers to my self-published books? I, too, am an unknown author without a chess title. My students may call me "Sensei", but I am not a master. I have been teaching beginners and novices, and a few strong local players who have become state champions. My skill at bringing young players up to C Class, and with a foundation that facilitates growing beyond me, is well-established. I have thousands of pages of instructional chess materials ready for conversion into e-book format. No one cares.

The Kindle store is full of rubbish. Even some of the books by established tournament players seem overpriced at $4.99. Some are incompetent. I titled one review of a book by a strong, young expert or master with that word. The author, who should know better, repeats an error that I have seen in several books, "the king cannot fork."*

In Essential Tactics, I have this exercise.

White to move

A king fork wins a piece and likely the game.


*That author currently has seven books in the Kindle store, several of which are always among the top sellers. One is no more than a ChessBase export file that any skilled ChessBase user could create in five minutes. In fifteen minutes, I could produce a cleaner copy.

Studying with Kramnik

Over the course of three sessions, I blitzed through all of the games in Chess Informant 130 that contain an ECO Code beginning with E.* As I did so, I made light notes that would guide me back to games that I wanted to examine further. This morning I played through part of Kramnik -- Vocaturo, Baku 2016, Informant 130/189 at the dining room table. Once I reached the position of the first diagram, I set Informant aside and opened my notebook. I remembered Kramnik's 17.Be7! From the position before that move, I tried to work out Black's principal responses and how Kramnik might have pursued his attack after each one. After recording my ideas in my notebook, I checked them against the annotations by Goran Arsovic.

After 16...h5
My first line is omitted from the annotations, perhaps because it is relatively simple. White wins a pawn and maintains an active position.

Black to move
After 17.Be7!
a) 17...Rd7 18.Bxf6 Bxf6 19.Nxe4 Bg7

In my second line, Black accepts White's bishop sacrifice.

b) 17...Rxe7 18.Nxc6

Black to move
Analysis diagram after 18.Nxc6
I rejected 18...Rxd2 as a critical line for Black, but it is presented in the Informant annotations. Again, White wins a pawn after 19.Nxe7+ Kf8 20.Nxc8. The line ends here, but it is obvious that a7 is en prise and Black has other difficulties. Trading rooks seems obligatory, which leads to a clearly winning ending for White.

My notebook has 18...Red7, which is inferior to 18...Rdd7 given in the annotations. My assessment of Black's defensive resources needs improvement here.

The critical line that I found was the line played in the game, but I mixed up the move order a few moves into the sequence.

17...Rxd4 18.Rxd4 Rxe7 19.Rd8+

I was not certain of this move after 19...Ne8 20.Rxc8 Bxc3 21.Rdd8 Kf8, thinking that Black might be better. White's attack has stalled and Black has two minor pieces for a rook.

Hence, I tried 19.Nxe4 Nxe4 20.Rd8+ Kh7 21.Bxe4 Rxe4 22.Rxc8 and assessed the position as unclear.

Kramnik's play appears more precise.

19...Ne8 20.Nxe4 Be6 21.Ra8 and Kramnik went on to win.

I have a long way to go before I can calculate the consequences of a move like 17.Be7!

Imagination in Chess

A Book Review

Paata Gaprindashvili, Imagination in Chess: How to Think Creatively and Avoid Foolish Mistakes (2004) has been on my shelf for more than a decade. I have read and reread it, and have often found myself repeating its advice to my students.

Gaprindashvili writes, "If we fail to make an idea work, we need to stop and ascertain the cause of the failure (i.e. answer the question 'why?'), and then attempt to correct our design" (40). This sentence, which I have paraphrased to my students on numerous occasions, forms the heart of what the author calls "reciprocal thinking," the title of the second chapter. Imagination in Chess is devoted to "the evaluation and development of the brain's reflective activity" (5).

The book contains a minimum of prose. The only chess books on my shelves with less text are those published in the language-less format of Chess Informant. Even so, the prose is focused and well integrated with the 756 exercises. Gaprindashvili urges his readers to read the first section of instruction, solve a few problems, read the next section, and so on. After passing through the book in this manner, the reader should go back through the book again, and again. With enough time spent repeatedly passing through Imagination in Chess, the thinking process will become second nature. Hopefully, "regular solving of the exercises will improve the cogitative action of the brain and raise your standard of play" (5).

The book contains seven chapters of decreasing length. The instructive portion is well illustrated with flow charts (see image below).


The thinking process advocated appears to be a refinement of Alexander Kotov's well-known "tree of analysis" in Think Like a Grandmaster (1971). It is refined in both its simplicity and flexibility. Gaprindashvili's first step is to study the position. "[I]dentify all of the tactical and strategic peculiarities" of the position (7). This process will reveal certain ideas from which will flow candidate moves. A student employing Kotov's process will then examine each candidate move in turn, analyze each candidate move for the opponent for each of these candidates, and so on. In Gaprindashvili's system, if calculation of the variations following from the first candidate move leads to a positive verdict, you play it. Kotov would hesitate until all candidates had been examined.

The chess positions comprise the bulk of the book. Although varying considerably in difficulty, these are generally quite challenging even to very strong players. They are also fresh. Most of the positions are not found in other books. Even readers who choose to ignore Gaprindashvili's system of progressive thinking, reciprocal thinking, mental agility, and imagination will benefit from study of the positions.

There have been criticisms of this book by those who take the time to check solutions via computer. For example, Sam Copeland explained in a comment to his "25 Books Guaranteed to Improve Your Chess" on Chess.com (12 January 2015) why he excluded this book. The book had been mentioned in a comment by Matty D. Perrine, who asserted it was the "best tactic book" he had gone through. Copeland said that he wanted to like Imagination in Chess, but found some of the solutions frustrating. He offers two examples from the first ten in the book. The diagram below is the book's sixth position.

White to move

Copeland may be correct that his solution is stronger than the one given in the book (my computer favors his at a depth of 34 ply), but the solution given was the one played in the game. The move played also reinforces the thinking process outlined in the first chapter.

Gaprindashvili's solution is historically accurate, but perhaps not the strongest move. The play after Copeland's move seems a little more straightforward. Some readers might prefer that alternate solutions to those played should be given in the book, especially when they are as strong or stronger.

While Copeland's criticism has some merit, I would recommend this book to my readers except for one small problem. the book is out of print. Consequently, new copies, when they can be found, are quite expensive. Amazon lists several third party sellers with the book for $118 plus shipping. Used copies start at $55. When I bought the book, it sold for $22.95.

Researching a Rook Ending

A rook ending that came up in Chess Mentor on Chess.com sent me to the books. The first two moves were easy, but then I lost my way. Once I absorbed the basic idea and found the correct answer within Mentor, I tried it again against Stockfish on the iPad. I went down several blind alleys before finding the correct route.

After learning to win the position easily against the computer, I went in search of additional instruction on this ending in my books. I pored through ten endgame books, including three that are entirely about rook endings, and did not find the position.

It does not appear in Grigory Levenfish, and Vasily Smyslov, Rook Endings (1971 [1957]); in Nikolay Minev, A Practical Guide to Rook Endgames (2004); nor in John Nunn, Nunn's Chess Endings, vol. 2 (2010). I also checked endgame books by Yuri Averbakh, Mark Dvoretsky, Reuben Fine, Mikhail Shereshevsky, and Jeremy Silman. In addition, I checked Smyslov, Vasily Smyslov: Endgame Virtuoso (1997); and Karsten Mueller, and Frank Lamprecht, Fundamental Chess Endings (2001). The last of these had the nearest equivalent, a version of the Kan ending below, but with more work to be done by the stronger side as the pawn behind the rook has not yet moved. That position is from Ivanchuk -- Yusupov, Horgen 1995 (Mueller, and Lamprecht, 198). The solution, however, is completely different due to the exigencies of the position.

The position in Chess Mentor purportedly comes from a game Smyslov lost to Mikhail Botvinnik in their 1954 World Championship match. The first match game, Smyslov -- Botvinnik, Moscow 1954 reached this position after 52...Ra3.

White to move

Smyslov played 53.Kh3 and resigned five moves later.

Had play continued instead 53.Kf2 a4 54.Kg2 Ra1 55.Ra5 a3 56.Ra7, the game would have reached the position that I found in Chess Mentor. This lesson appears in "Rook and Other Endgames", a course created by Jeremy Silman. From the position in the photograph above, the student is presented with these directions.
This endgame would be confusing to most players, however a good understanding of Variations One and Two immediately tells you the dream positions that you would like to achieve. This shows that a working knowledge of basic situations allows you to easily solve otherwise difficult problems. In the position in question, Black must decide when to take on g5 and when to push his a-pawn to a2.
Silman, "Rook and Other Endgames," Chess Mentor, Chess.com
Silman's assertion that Botvinnik played this ending is thus somewhat misleading. That it did not occur in an actual game also serves to explain its absence from textbooks.

Some of the pitfalls that White must avoid are easily found in books. For example, after many moves, Black might threaten a skewer. Minev, A Practical Guide to Rook Endgames presents this position almost at the very beginning of the book (12).

White to move

In my database, I found another game played in the Soviet Union a few years before Smyslov -- Botvinnik that reached a final position where White could no longer avoid this skewer.

White to move
After 65...f4
In Rabinovich -- Kan, Moscow 1935, White resigned in this position. Silman's course offers several exercises almost identical to this position that guides the student to understanding why White chose to resign. White either blockades the pawn with 66.Kf3, allowing 66...Rf1+ and promotion of the pawn, or permits the skewer after 66.Kf2.

I did not initially see a final position like that in Kan's game from the position in Chess Mentor, but nonetheless understood that advancing the a-pawn first created such threats.

Chess Mentor Screenshot
After a couple of correct moves, Silman points out that Black has moved his king towards the center. His note refers the user to "Variation Five", a perplexing reference (see comments on Chess Mentor below). In any case, I was able to discern through trial and error the correct plan and complete the lesson. Then, I played it out against Stockfish with colors reversed.

Stripes,J -- Stockfish
30.01.2017

1.h7 Rh3+ (in Silman's lesson, White shuffled the king between a7 and b7) 2.Kxb4 Rh4 3.Kc3 Rh1 4.Kd3 Rh2 5.c5! bxc5 6.c4

Black to move

This position is "a well known theoretical win," according to Silman. Naturally, I thought it must be in some of my endgame books. In my battle with Stockfish, I tried getting my king to b5, which was possible. However, Black simply sticks the rook on h5 and shuffles the king between a7 and b7. I discovered that I needed to walk the other way.

In my second game against Stockfish, I set up the position with the colors as they are in the lesson.

Stockfish -- Stripes.J
30.01.2017

1...a2 2.Ra6+ Kxg5 3.Ra5 Kf6 4.Ra3 Ke6 5.Ra5 Kd6

This time I headed in the right direction even prior to advancing my f-pawn, a slight inaccuracy it would seem from Silman's lesson, but one that did not matter against Stockfish.

6.Ra8 f4 7.gxf4 f5 8.Ra5 Kc6 9.Ra8 Kb5 10.Ra3

Black to move

10...Kc4 11.Kh2 Kd4 12.Kg2 Ke4 13.Ra5

I unnecessarily expended time worrying about 13.Ra4+, thinking the rook could stay there. But, then I realized that White cannot plant the rook and shuffle the king because I can play Kf3 either forcing the rook to abandon protection of the pawn or walking into checkmate with Ka3.

13...Kxf4 14.Ra8 Ke5 15.Re8+ Kd6 16.Rd8+ Ke7 17.Rd2 f4 18.Rf2

Black to move


18...Rg1+ 19.Kxg1 a1Q+ 20.Kg2 Qc1 21.Ra2 Qe3 22.Rf2 Kf6 23.Rf3 Qe4 24.Kf2 Kf5 25.Rh3 

Black to move

At this point matters are quite simple. The exercise is over. However, Stockfish is not set to resign, so I play until checkmate or abandon the game. The rest of the game required only a few seconds.

25...Kg4 26.Rh8 Qd4+ 27.Ke1 Qxh8 28.Kd2 f3 29.Kc2 f2 30.Kb1 f1Q+ 31.Kc2 Qd4 32.Kb3 Qb1+ 33.Ka3 Qdb4# 0–1


Some Thoughts on Chess Mentor

Chess Mentor was developed several years ago as stand alone software. It remains available as such through their website. In addition, at some point several years ago, the owners of Chess.com purchased the rights to this product. The entire package is embedded within Chess.com's "Chess Lessons" (version three), where it was called "Chess Mentor" under versions one and two. It is available to premium members.

Embedding stand alone software into a web-based format was not accomplished seamlessly. Comments such as Silman's reference to "Variation Five" do not reference anything that can be found under that name in the web version. Sometimes, as in this particular exercise, the carefully crafted teaching modules of Chess Mentor break down.

The original Chess Mentor also offers a "hint" feature, but Chess.com's site design does not implement this feature.

In general, the lessons in Chess Mentor are well designed. I am finding it useful to go through elementary level lessons in search of ideas to use in my teaching, and more challenging lessons as an aid to my own improvement. The lack of an embedded hint feature often leads to blind trial and error until I stumble across the correct move. That groping in the dark can provoke frustration.

Chess.com also gives users a "Lessons" rating. One would not expect to gain rating points from a lesson rated far below one's current rating. However, I have made every correct move in dozens of easy lessons only to discover that I scored 94% and suffered a rating loss of 10 points. I care little enough for the rating, but the logic of 94% for a string of correct moves mystifies me.

It seems to me that Chess.com could invest some of the money it collects from premium users to hire people who can edit the comments to remove references that lead no where and to debug the rating and evaluation system. On the other hand, maybe the technical difficulties of such a task are overwhelming.

The "Lessons" on Chess.com are useful with a few caveats.

Patterns: Some Evidence

Working through a lesson series called "Advanced Tactics" on Chess.com, I came across this problem.

Black to move

The diagram is upside down (Black on bottom).

This lesson series was created for Chess Mentor by Thomas Wolski. It contains many lessons from the games of Wilhelm Steinitz. In addition to enjoying the tactics practice, I am becoming impressed with Wolski's ability to extract lessons from Steinitz's play. I am beginning to think that a more sustained study of the first official World Champion's games might be in my future.

I spotted the first several moves of this combination in one second, that is, instantly. This instant recognition of most of the solution, and the confidence that the rest would be forthcoming stemmed from having seen essentially the same ideas in two other problems that I put in front of youth players in the past two weeks. See "Carlsen's Queen Sacrifice," problems 3 and 6.

This instant recognition strikes me as evidence of pattern recognition as an element in the development of chess skill (see "Patterns and Calculation").

Empty Promises

Year in Review

2016 was a rough year that dropped my USCF standard rating to 2009 levels. In 2007, my rating climbed over 1700 for the first time, albeit briefly. In 2008, it appeared that I would keep it over 1700, but then in the first event of 2009, it fell again to 1698. Then, five months later, I hit 1800! My rating continued to rise, reaching a peak of 1982 in mid-2012. After that height, it was up and down, but mostly slowly dropping. I fell under 1900 a couple of times, but then brought it back up through 2014. In 2015, it fell to 1847, but then I won a weekend Swiss and it popped back up to 1902 (see "Winning an Open"). The last event in 2015 end every event in 2016, except the last, dropped my rating further. In October, I fell to a six year low of 1750.

Later in October, my play seemed better. I won a quick event at the Spokane Chess Club four days after winning an online USCF rated tournament (see "Winning"). Then, in November, I placed second in the Spokane Game 10 and won my section of the Turkey Quads 3-0, lifting my rating to 1791. I have become a B Class player, but the year seems to end on a positive note.

In late December, I managed to lift my Chess.com tactics trainer rating over 2000 for the first time since the early years of the site when such ratings seemed grossly inflated (I have a peak of 2400).

Resolutions

Chess Skills has documented many New Year's Resolutions aimed at chess improvement. None were kept all year, although several lasted into the summer. 2013 was a particularly ambitions year (see "A Time for Reflection"). My goal was to make expert (USCF 2000+), but the resolutions were training oriented. Well into the summer, I posted monthly spread sheets showing my tactics training progress with the accompanying narrative assessing the other goals--whole games, pawn endings, and weight loss. I admitted failure in November.

My resolutions each year since then have been less ambitious, and yet remained unfulfilled (see "Year in Review 2015").

A Fool's Errand

With such a fabulous track record, my resolution for 2017 should be to avoid setting any goals. Stubbornness gets in the way, however. I want to set a goal.

My attitude changed a bit after my abysmal performance in the Eastern Washington Open. I started making time for study again. The main behavioral change was that I started using Chess Mentor and the videos on Chess.com with some regularity. These resources are the reason that I pay for Diamond level membership. It would make sense to set some goal regarding regular use of these resources. For example, I might set out to complete a certain number of lessons each week, or watch a particular series of videos each month.

I need to focus on thinking. I need to look at the position in front of me when I am playing, slow down, and calculate. Tactics training can help. So, can chess mentor.

But, I need a resolution that I can keep.

In 2017, I will set up a chess board on my dining room table and play through games from a printed book. I will perform this task at least once each week.


I make no promises to myself to complete any particular book, but I do plan to make use of several in a manner that balances classic games with contemporary. Hence, I will read portions of Tartakower and DuMont, 500 Master Games of Chess (1952) as well as the latest issue of Chess Informant.

Protect the King

A game brought to my attention by a video lesson by Dejan Bojkov on Chess.com offers a nice display of Ann Chumpitaz's king hunting skill. The game was played in the Continental Championship in Lima, Peru last February.

Determination

Reading Chess Informant

Last Thursday, Chess Informant 128 arrived via courier. With each new issue, I resolve to read all the articles or play through all of the games in the traditional section (see "Discovery"). With each new issue, I fall short of my goals.

I am determined to establish a new pattern, reading all of Informant 128.

Since Thursday, I have read all of the narrative text in Ernesto Inarkiev, "Moscow Candidates Tournament 2016"; Aleksandar Colovic, "Moscow Opening Report"; and Sarunas Sulskis, "European Championship 2016". I also solved rather quickly the first ending and was working on the second when I was interrupted by a text message that required action. Using the CD version that comes with the printed book, I have been working through the games and analysis in Inarkiev's article.

Black to move

Sergey Karjakin played 17...cxb4.

Inarkiev's comment brought my reading to a halt. He writes, "This is a tempting decision. Black sacrifices his queen for a rook, minor piece and a pawn, a balance of material that is usually sufficient" (18). My eye did not perceive the danger to the queen until I saw 18.axb4 Bxc3 19.Nc6 on the board, and only then could I begin to calculate the resulting imbalance.

Karjakin's determination at the Candidates shines in Inarkiev's narrative and analysis. The depth of the analysis and the complexity of the games reveals to me that my determination to read all of the issue clear through will require a significant investment of time.

My reading of Informant goes back two decades. The quality of my play has benefited. On this blog, I wrote about the first tangible benefit--a correspondence win in the 1990s--in "Playing by the Book" (March 2011). In a more recent correspondence game, I had this position with White.

White to move

Our game had been following Botsari -- Polgar,J, Eretria 2011, which Polgar won. Botsari played 28.Re7 and Polgar's pieces put an end to White's initiative. Apparently unbeknownst to my opponent, however, was the analysis of this game in Informant 112/51 by Dejan Antic who recommended 28.f7. I played that move and our game followed Antic's line 28...Rg7 29.Re8+ Nf8 30.Qd6 and then instead of the necessary 30...Qh4, my opponent played 30...Qh5+ and I won a few moves later.


Improving

If I continue to read Informant in bits and pieces and utilize my complete collection in electronic format as a reference in correspondence games, I will continue to see benefits. But I want more. I remain determined to improve my performance in USCF tournaments, reverse the slow downward slide that has been occurring since summer 2012, and renew efforts to push to a new peak rating (see "Eleven Consecutive Wins!" [July 2012]). I believe that Informant is among the most useful tools that I have for improving.

In the wake of my tournament success in 2012, I purchased Informant 113 as book and CD combination. Prior to that point, I acquired most of my Informant books after they went on sale because they were a year or more out of date, and acquired even more electronically via the CDs that had a year's worth. Gaps in my collection were filled when I placed fifth in the Reader's Contest for those who purchased Best of the Best 1000 (2008). When I bought Informant 113, I had a complete collection through the current issue. Several months later, when my collection was no longer current, I began systematically working through the games section (see "Training Log: August 2013"). That enterprise lasted several months, but eventually gave way other training priorities and my recurring obsession with blitz.

I bought a few more multi-issue CDs in 2014. Then, with download editions of Informants 119, 120, and 121, I was up-to-date with the latest issues. These were followed with timely downloads of Informants 122 and 123, keeping me current. Beginning with Informant 124, I became a subscriber. Each issue becomes the center of my chess focus for a few weeks after its arrival, but I never get through more than a fraction of the issue. I skim several articles and play through the games that interest me. Several printed issues contain brief notes that I make as I go through the games on the screen of my computer.

I am determined that with Informant 128 I will maintain the focus and self-discipline to work through every article, the games section, and the endings and combinations sections. There will be distractions. Since Thursday, I have played dozens of blitz games online. I also remain committed to study of Greco's and Morphy's games. I use these with my students. Time spent reading Informant must balance with study of classics.

The time and effort spent on Informant will improve the quality of my play.
