300 Most Important Chess Positions

A Book Review

If you follow Chess Skills, then you know that I've been working through Thomas Engqvist, 300 Most Important Chess Positions (2018) at a pace far more accelerated than recommended by the author. When I announced this 60 day effort in December, I noted, “failure may be expected”. I worked through the last four positions this morning, the 74th day.

I heartily recommend this book. Studying five positions per week, as the author suggests, improves retention, and likely long-term benefits from study. Having raced through the book, I will be reviewing and deepening my study of many positions in the book over the coming months.

Engqvist’s 300 positions are selected from classical games, recent master practice, and compositions. Engqvist also includes some of his own most instructive losses. He is guided by a library of chess books, many years of playing, and experience coaching. The core idea of deep study of a limited number of positions developed from the way he was coached by Robert Danielsson while a young player. He studied positions from Ludek Pachman’s books on the middlegame and endgame.

Alekhine builds his gun
In the introduction, Engqvist makes a case for careful, disciplined study and focus on a limited number of positions per week. This contrasts markedly with Jeremy Silman's recollection that as a young chess player, he went through "200 to 500 games a day, every day" ("Studying Master Games and Berkmaster's First Over-the-Board Tournament Battle"). Silman claims that he absorbed tactical patterns and positional concepts in this manner. Engqvist advocates reflection and review with intent to "understand, grasp and assimilate the most important idea(s)" (9). He asserts that studying too many positions at once lead you to forget what you have learned. At the core of this learning process, he writes, is "to gain a deeper appreciation of the inner qualities of the pieces, their movements and their actual value in any specific position" (emphasis in original, 9).

By way of illustration, he offers this composition by Paul Rudolf von Bilguer from 1843.

White to move
This position appears in the introduction and as number 281 in the text. Both Ludek Pachman and André Chéron advocate 1.Qe6 and consider the position a draw, but tablebases show that it is a win. There is much to attempt to absorb in the tablebase moves that Engqvist annotates (274-276), but he notes that sometimes the queen works best when it does no more than a rook can do (9). 1.Qc7! is the only winning move. The queen's demotion explains the first move, but subsequent moves draw on the full mobility of the queen, leading Engqvist to marvel at "how the attacker uses the queen over practically the whole board" (276).

The positions that he chooses are interesting, challenging, instructive, and practical. Most of them were tested with chess players who subscribed to an email course where they were presented five positions per week. Rarely is a single move or short sequence the solution that one must find while examining the position. Only a few offer long computer solutions as in the Bilguer study. A considerable number of positions feature equal or near equal positions from games where strong moves and persistent maneuvers eventually provoked error.

Many of the positions are suitable for training with a study partner. Engqvist recommends playing both sides with another person, or against the computer. Teaching the position to someone else improves retention he notes, and in my experience also depth of understanding. My young students often vex me with moves that were not anticipated in master commentary or computer analysis. The positions in this book are excellent resources for coaches. The day that I acquired this book in February 2019, I took it to a lesson with my top student. We looked at six endgames and then the first position in the book (see "A New Book and a Morphy Game"). The next few weeks, this student and I will be playing some of the rook and queen endings.

Emphasis is on positional concepts, rather than tactical operations. The author notes that this emphasis distinguishes his book from Lev Alburt, Chess Training Pocket Book: 300 Most Important Positions and Ideas (1997), which emphasizes tactics. Alburt also limits the number of endgames. He states that becoming a "strong player" requires knowledge of 12 key pawn endings, not hundreds (9). These 12 are in his Pocket Book. Alburt's book is the second one that I list in "Ten Books to Achieve 1800+".

Some positions in 300 Most Important Chess Positions are surprising, such as White’s second move in the English Opening, Sicilian Reversed.

White to move

But this position is placed alongside others (both English Opening and Sicilian Defense) with references to several games played by top players. There is plenty of study material in these games. I might also note that Engqvist’s opening choices reflected in the positions chosen offer more variety than those in another collection of 300 positions that I’ve spent time working through: Rashid Ziyatdinov, GM-RAM: Essential Grandmaster Knowledge (2000). Ziyatdinov’s positions stem from games where 1.e4 is the overwhelming choice.

An instructive sequence of positions that I found highly motivating began with Bologan,V.--Frolov,A., Moscow 1991, a Sicilian Defense, then in a variation continued with Anand,V.--Illescas Cordoba,M., Linares 1992 and reference to Karpov,A.--Kasparov,G., Moscow 1985.  It continued with Bologan--Frolov for two more positions, then Marin,M.--Korneev,O., Capo d'Orso 2008 takes us through moves 2-4 through three positions in the English Opening, Sicilian Reversed.

The first position in the book is slightly less surprising, but with two book moves played by Adolf Anderssen and Paul Morphy, as well as many other players before and since, Engqvist’s preference for Morphy’s choice provokes reflection.

White to move
9.Nc3 and 9.d5 both get played by masters today. Adolf Anderssen favored 9.d5 and won many games from this position. Paul Morphy showed, Engqvist suggests, that 9.Nc3 is a better developing move.

As I consider Morphy’s 9.Nc3 in the Evans Gambit or Mihai Marin’s view that after 1.c4 e5, 2.g3 is the most precise, I am reminded of my tendency to blitz out opening moves by rote and only begin thinking after an inaccuracy. Engqvist’s positions from very early in the game should help me to develop better habits. Thinking should begin before the first move, even if positions at move 10 are well-studied.

There are positions in this book that I have used with students for many years and there are positions that are wholly new to me. There are many positions with several pages of analysis and variations. There are positions that should be drawn, but one player was able to present sufficient difficulties to provoke error.

Ziyatdinov advocates memorizing the 56 games from which he draws the middlegame positions; Engqvist is more selective in games that he suggests the student commit to memory. Schulten -- Morphy, New York 1857, a King's Gambit that Morphy won in 21 moves, appears in both and I'm close to having it in my long-term memory. I have not yet started the effort to memorize Karpov,A.--Unzicker,W., Nice 1974, which is another suggestion of Engqvist's.
One position that I studied in early January led me to improve my move order in a position that I frequently reach while playing against the Caro-Kann.

Several endgame positions that I played against Stockfish before or after reading Engqvist's notes drove me to dig into some of the volumes in Yuri Averbakh's eight-volume series.

Engqvist's analysis is fresh, lucid, and thought-provoking. Many of his memorable phrases guide me when they should--appropriate moments during play. For example, "Nimzowitsch tried to make his opponent tired and careless by doing nothing" (230). In Duras -- Nimzowitsch, San Sebastian 1912, more than twenty moves of rooks and kings were played in a completely equal endgame. Only when Duras erred did Nimzowitsch move a pawn.

I reflected on this lesson while playing online a completely drawn ending of bishop and knight versus bishop, and then nine moves prior to a draw by the 50-move rule, my opponent allowed a small combination that allowed me to win his bishop. That game, then, became my first opportunity to checkmate with bishop and knight that did not result from a deliberate underpromotion. Because of Engqvist's choice of positions, I had recently practiced that checkmate, too (see "Recognizing Known Positions").

300 Most Important Chess Positions was on my shelf nearly six years, serving as occasional study material and reference for finding positions suitable for some of my students. Now that I've been through every position, I will use it more actively.

I have a to do list that developed as I was going through the book. The list includes studying Jose Capablanca's analysis of a couple of his games in My Chess Career (1920), the only Capablanca authored book that I did not wholly read in 2021. Engqvist brought to my attention a game that Richard Reti analyzes in Master of the Chessboard (1930), which I intend to study. Some of Engqvist's analysis draws from Victor Bologan, Victor Bologan: Selected Games 1985-2004 (2007), and I added it to my library. The long rook endgames and queen endings are games worth reviewing periodically until I absorb their lessons.

Another task presented to me after racing through this book is that Engqvist has also published 300 Most Important Tactical Chess Positions (2020), 300 Most Important Chess Exercises (2022), and Chess Lessons from a Champion Coach (2023). Any or all of these books would be worth my time. Perhaps I'll continue to ignore Engqvist's advice on pacing, and race through his tactics book in the near future.

Lasker's Originality

I am watching chess videos that are part of the Fritz Trainer DVD, Master Class, vol. 5: Emanuel Lasker (2015). Mihail Marin makes the argument that Emanuel Lasker was an original strategic player who sought to bring new ideas into familiar openings. In the fourth game of his World Championship match with Siegbert Tarrasch, Lasker brought his rook to the fifth rank, then transferred in to the fourth, where tactical complications ensued. Tarrasch made a few small errors, leading to this position.

How should Black deal with the fork?

Attack with Simple Moves

The past two days I have been going through games and analysis in Mihail Marin's column in Chess Informant 136, "Attack with Simple Moves" (47-58). The 1967 game Portisch -- Petrosian, in particular, captured my interest.

Portisch,Lajos -- Petrosian,Tigran V [D13]
Moscow 3/584, 1967

1.d4 d5 2.c4 c6 3.cxd5 cxd5 4.Nc3 Nf6 5.Nf3 Nc6 6.Bf4 e6 7.e3 Bd6 8.Bg3 0–0 9.Bd3 Re8 10.Ne5 Bxe5 11.dxe5 Nd7 12.f4

Black to move

12...Qb6

Mikhail Yudovich, who annotated the game for Informant 3, gave this move a question mark. Marin adds, "A curious 'pawn grabbing based' plan with incomplete development" (53). Curiously, the diagram position has occurred in at least 18 games (Portisch -- Petrosian was the second) and 12...Qb6 has been played in 13 of these.

In the one previous game, Max Euwe won from the Black side in 20 moves after 13.Qe2. But White has a healthy 65% score over the 13 game batch.

13.0–0 Qxe3+

Yudovich recommends 13...Nc5, which still remains unplayed in subsequent games.

14.Kh1 Qb6

After 14...a6, Black went on to win in Stobik,D. -- Hoffmann,H., Germany 1977, and also in Pira,D. -- Van Rompu,A., France 2008.

White to move

15.Qh5

15.Nb5 was played in the only other game to reach this position, and Black won, Dreyer,M. -- Mohammad,S., Yerevan 1996.

15...Nf8

Marin offers two alternatives: 15...h6 and 15...g6. My computer suggests that 15...g6 is Black's only hope for eqauality.

16.Rf3 Ng6 17.Bf2 Qd8 18.Nb5

Marin notes Black's "chronic weaknesses" (54). This position is the sort that I am always in search of to present to my students for illustrating the consequences of pieces that are mere spectators. All of White's pieces are in the battle on the kingside, or will be soon. Most of Black's pieces are doing nothing.

18...Nce7 19.Nd6 Bd7

White to move

20.Bh4

20.Nxe8 wins the exchange, but gives Black time to bring the rest of his pieces into the game. It is a grave error to exchange a strong attacking piece for a spectator.

20...Qb6 21.Rh3 h6 22.Bf6 Qxb2 23.Rf1 Nf5 24.Bxf5 1–0

Checkmate comes soon.

Minor Piece Ending

Studying with Mihail Marin

Mihail Marin annotated Stefanova -- Pogonina, Tehran 2016 for Chess Informant 127. It was Stefanova's only win in the event, the second of four events comprising the FIDE Women's Grand Prix. After 28 moves, each player had a knight, bishop, and seven pawns.

White to move

Marin asserts this position is equal. Twenty moves later, White had a clear advantage.

White to move

Stefanova did not play the optimal move here, but played well enough to maintain an edge, albeit not necessarily a winning advantage.

Marin labels as dubious Pogonina's move from this position, and indicates that both players erred on the following move.

Black to move

Then, White's move 63 is given a double exclamation mark--a brilliant move.

White to move

I ask myself, would I find Stefanova's move here if I looked at this diagram after I forgot the game? I think the game and the annotations are interesting and instructive.

Converting an Advantage

My copy of Chess Informant 125 arrived on Monday and is already proving challenging. As a long devotee of the French Defense who occasionally adopts the Rubinstein, my attention fell quickly upon Alexander Morozevich's "Midnight in Moscow".  I will devote considerable time to this article in the coming weeks.

Then, there is an abundance of games from the Sinquefield Cup annotated by Aleksandar Colovic, Sarunas Sulskis, and Michael Roiz. The English language content goes on through more than half of the volume, and includes the second installment of "The New Romantics" by Pentala Harikrishna. Mihail Marin's "One Golden Rule -- Development" is the latest installment of his "Old Wine in New Bottles," a column I always make a point of reading.

Turning to the traditional games section in Informant codes, the first game offers a challenging study. White's opening faltered and Black gained the advantage. The annotator offers suggested alternatives for more than half of both players' moves. Black blundered from the position in the first diagram and White turned the tide.

Black to move

How would you play this position? How would I? I am mulling over the position while I consume my morning coffee.

Expose the King!

In a recent correspondence game, I found a single reference game in which Black's play struck me as a bit timid.

Black to move

My database contains six games that reached this position, one with White to move. I only looked at those games played by masters (ratings above 2200). The highest rated Black player continued with 10...Ne5.

10...Bd6 was played in the other two games. White must address the threat to h2.

11.f4

My opponent threatened e5, following one of my reference games.

11.g3 was attempted in the other reference game. That did not go well for White. 11...Bxg3 12.hxg3 Qxg3 13.Kh1 Ne5 14.Nc5 Nfg4! 15.fxg4 Qh3+ 16.Kg1 Qxe3+ 17.Rf2 Qxc5 and White resigned after two more moves. Brynjarsson -- Bjornsson, Reykjavik 2009.

11...b4

I studied the remaining reference game, and noticed that Black gained an attack on the king. Black's attack faltered, but need not have done so. Initially, Black seems to sacrifice a knight but gains three pawns for the piece. Another sacrifice, however, this time for a single pawn fatally exposes the White king. This second sacrifice was not played in the reference game.

12.e5

The fork.

12...Nxe5

Beginning a tactical operation that exchanges a knight for three pawns and leaves the White king exposed.

13.fxe5 Bxe5 14.Nb1N

The reference game continued: 14.Na4 Bxh2+ 15.Kh1 Qg3 (15...Bxg2+! 16.Kxg2 Qg3+ 17.Kh1 Qh3 18.Rf2 Bf4+ 19.Kg1 Bxe3 and Black has recovered the material with interest.) 16.Bf3=  and the game was drawn in 42 moves. Toubale,T -- Villeneuve,A (2345), Cannes 1989.

14...Bxh2+ 15.Kh1 

Black to move

I had been aiming for this position.

15...Bxg2+! 

As seen in the reference above, 15...Qg3 gives White time to organize a defense.

16.Kxg2 Qg3+ 17.Kh1 Qh3

White to move

18.Rf3

18.Rf2 is better 18...Bf4+ 19.Kg1 Bxe3 20.Qf1 Qg3+ 21.Qg2 Bxf2+ 22.Kf1 Ne4–+.
18.Rxf6 fails. 18...Bg3+ 19.Kg1 Qh2+ 20.Kf1 Qh1+ 21.Bg1 Qh3#.

18...Bg3+ 19.Kg1 Qh2+ 20.Kf1 Qh1+ 21.Bg1 Qh3# 0–1

Finding the decisive blow was almost certainly helped by my having read earlier this summer several of Mihail Marin's recent columns for Chess Informant. In particular, for Informant 122 he wrote, "Is Chess a Matter of Memory? Lasker's Double Bishop Sacrifice."

Giuoco Fortissimo

In Chess Informant 124, Mihail Marin examines the ancient history and recent practice in the so-called quiet game, or Giuoco Piano ("Old Wine in New Bottles," 82-94). He suggests that in the games of Gioachino Greco and in some recent games, the term fortissimo might be more appropriate than piano or pianissimo. Lines with 4.d3, advocated by William Steinitz and many players since merit the name Giuoco Pianissimo. But play in the spirit of Greco is anything but quiet.

Fortissimo is an apt description of Greco's miniatures and of a curious game in I.A. Horowitz, Chess Openings: Theory and Practice (1964). I know of two other books that contain this game: Irving Chernev, The 1000 Best Short Games of Chess (1955),* and Leonard Barden and Wolfgang Heidenfeld, Modern Chess Miniatures (1960).

The game is said to have been played in Mar del Plata, Argentinia in 1946. Both Cesar Juan Corte (1914-1996) and Jacobo Bolbochan (1906-1984) played in a major tournament in Mar del Plata in 1946, but this game was not from that event. It may have been part of another event that year, or it could have been a off-hand game.

Chernev claimed that he went through 15-20,000 games in order to select the 1000 for his classic text (see Edward Winter, "Irving Chernev," http://www.chesshistory.com/winter/extra/chernev.html [updated 14 December 2014]). However, he offered no documentation of his sources. I have not seen a copy of Barden and Heidenfeld, but would be surprised if it offers documentation of sources. It would likely take many hours of digging through late-1940s chess publications in order to locate a primary source for this game, and possibly more information concerning the circumstances of play.

It is an instructive game, nonetheless. It is no surprise that Horowitz saw fit to include it in his opening encyclopedia.

Corte,Cesar Juan -- Bolbochan,Jacobo [C54]
Mar del Plata, 1946

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5

I found four other games in which Bolbochan played the Black side of the Italian. He played 3...Nf6 in two of them. In the two other instances when he played 3...Bc5, one is an Evans Gambit, and in the other White played 4.d4.

4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Nc3 Nxe4 8.0–0 Nxc3

A few years later, Corte faced the line preferred by modern theory: 8...Bxc3 9.d5 (9.bxc3 d5 White lacks compensation for the pawn. Black's chances are better.) 9...Bf6 10.Re1 Ne7 11.Rxe4 0–0 Corte,C -- Martin,P, Mar del Plata 1949 was drawn in 67 moves.

9.bxc3 Bxc3 10.Ba3!

This move was recommended by James Macrae Aitken in an article in British Chess Magazine (1937). Horowitz mentions it as a suggestion of Aitkin, and opines that it is stronger than Greco's 10.Qb3.

Black to move

10...d5

This reply is best.

A game in the Mar del Plata International Tournament of 1946 continued 10...Qf6 11.Qe2+
(11.Rc1 is better. 11...Ba5 12.d5 d6 13.dxc6+-)
11...Kd8 12.Rad1
For the cost of two pawns, White has all of his pieces mobilized. Nonetheless, Black went on to win after a long struggle, Reinhardt,E -- Maccioni Seisdedos,A, Mar del Plata 1946.

11.Bb5 Bxa1 12.Re1+ Be6 13.Qa4 

Stockfish 6 prefers 13.Qc2 Qd7 14.Ne5 Nxe5 15.Bxd7+ Nxd7 16.Rxa1.

Horowitz gives the moves to this point in practical variation 1, stating that White has a winning attack.

Black to move

13...Rb8??

13...Qb8 is equal according to my chess engine 14.Bxc6+ bxc6 15.Qxc6+ Kd8 16.Rxe6 fxe6 17.Ne5 Qb1+ 18.Bc1.

14.Ne5 Qc8 15.Bxc6+ bxc6 16.Qxc6+ 1–0

The Spirit of Greco

Should aspiring chess players study the games of players who have been dead for more than a century? In an interview conducted while he was World Champion, Vladimir Kramnik answered in the affirmative.
I think that if a player wants to achieve much, he should live through the entire history of chess in his thoughts. I can't explain it from a purely logical standpoint, but in my opinion, you have to experience the entire history.
Vladimir Kramnik, 2004*
The interviewer probed further, asking whether it was useful to go back as far as Gioachino Greco. Kramnik did not think Greco was necessary because Greco's games are only the basics of chess, but he thought aspiring players should know the games of Philidor, Anderssen, and Morphy.

Max Euwe expressed a similar view of the importance of chess history. He asserted in The Development of Chess Style (1966) that an individual player's development and chess history follow parallel courses. The longest and most difficult is the first stage, which Euwe characterizes as "excursions with the pieces" (1). Players succeed when they take advantage of the opportunities presented by opponents, "such as winning a piece" (1). Greco embodies this first stage, he suggests.

Euwe annotates two of Greco's games. In another 300+ volumes in my library, I look in vain for annotations of Greco's games. Several books make passing reference to his collections, usually by noting that some tactical idea or opening move "has been known since Greco." Garry Kasparov, My Great Predecessors, Part I (2003) is a notable exception. On the first page of chapter 1, he presents a synopsis of Euwe's argument (without attribution) and four Greco games. In two of the games, he offers a small number of suggested improvements. But Kasparov offers no verbal annotations, no detailed analysis.

Euwe also offers one game by Andre Philidor. Philidor's games, too, are mostly absent from other books. In Philidor's case, however, many more writers mention his contribution towards understanding the centrality of pawns to chess strategy. Kasparov offers one game fragment from Philidor with annotations. His views align well with Kramnik's concerning the merits of Philidor.

Last week, however, DHL brought an exciting new book hot off the presses that offers fresh annotations of the second of the two Greco games featured in Euwe's classic. This new book is Chess Informant 124. In this volume is the tenth installment of Mihail Marin's column, "Old Wine in New Bottles."**

Marin sets out to contextualize the explosion of information that we observe in this era of computers. He challenges a common belief that this explosion is without precedent. He recalls similar claims in opening monographs of the 1970s and 1980s. Even the first systematic opening reference, Handbuch des Schachspiels (1843) describes an explosion of information in its day.

Marin does not stop at simply challenging perceptions that our age is unique due to a massive increase in the information available to us. He also traces the development of new ideas with the point of showing that they are not so new after all. Tracing the continuities between old and new offers an affirmation of the value of studying classic games.
In every game, there comes a moment when a novelty inevitably pops up, but one cannot be sure that the idea behind it has not been played before.
Mihail Marin, Informant 124, 82.
Marin's focus in Informant 124 is the Italian Opening, particularly the Giuoco Fortissimo. He begins with Nakamura -- Giri, Khanty-Mansiysk 2015.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+

White must either Block the check or move his king. Greco blocked with 7.Nc3 and these days 7.Bd2 is preferred. Nakamura, however, played a relatively rare move: 7.Nbd2, which sacrifices a pawn. I can find approximately one hundred instances of this move in my database.

Black to move

After 7...Nxe4, Nakamura shows that he is playing in the spirit of Greco with 8.d5, "fighting for space and an advance in development" (83).

After Nakamura -- Giri, Marin offers analysis of one of Greco's best games. Then, there is another game from Khanty-Mansiysk. Jobava -- Grischuk featured 6.e5 d5, which the author notes is reminiscent of several games played by Morphy and Anderssen. Jobava repeated his opening experiment in a later round of the same event, and Marin refers readers to the column by Sarunas Sulskis, where that game in analyzed in depth.

"Old Wine in New Bottles" continues with an instructive game when Marin lost on the Black side of the not so quiet Italian Game, and then a World Championship game where Karpov employed the quieter line with 5.d3 for the purpose of torturing Korchnoi. But this quieter line still permitted fortissimo in Bologan -- Marin, Bucharest 1990 (a friendly blitz game). Marin finishes the article with a third game of his own and then Dubois -- Steinitz, London 1862, which had been one of my study games a few months ago (see "Some Miniatures").

Marin's column offers a good mix of old and new, of famous games and those less well-known. His ongoing column builds the logical argument that Kramnik deferred in his 2004 interview.

The New Informants

Long a publication that crosses language barriers, in recent years Chess Informant has been expanding its front sections with articles written in English. These changes began with opening theory and expanded into articles on many topics.

Informant 110 offered a new feature called CI Labs with five articles concerned with new trends in the openings. Each article contained a short introduction in English. CI Labs expanded to six articles in the next issue, which also added two other articles. "Chess History" by Harald Fietz celebrates the centenary of Jose R. Capablanca's entry into the world elite. Anna Burtasova's "Women and Chess" marked the 50th birthday of Maia Chiburdanidze, five-time world champion.

CI Labs peaked at ten articles with Informant 113 and that issue also included the first "Garry's Choice" column, which ran through Informant 118. In these columns, Garry Kasparov offered his analysis of recent Grandmaster games. The number of articles continued to grow as did their breadth and depth. With Informant 119, the company added download versions customized for the ChessBase database software. Because I use ChessBase daily, this feature puts Informants in easier reach.

The new content is outstanding. While Informant has long been a periodical that was indispensable to professional players, some average players found it intimidating. Many of the new articles aim at the average tournament player.

Mihail Marin's column, "Old Wine in New Bottles," has proven illuminating. In Informant 119 (the Viking edition), he explored rook endings. Viswanathan Anand missed a draw in a difficult rook ending in his World Championship match with Magnus Carlsen. Most chess enthusiasts know that, but still may find Marin's analysis illuminating. In the same article, he points out a hidden resource in the well-known game Capablanca -- Tartakower, New York 1924. Marin poetically notes that the reputed author of the aphorism, "all rook endings are drawn," missed a drawing opportunity in his most famous loss.

In Informant 122, Marin examines the role of memory in chess through an exploration of the double bishop sacrifice. He works his way back through time, beginning with recent play by a teammate and working towards Emanuel Lasker's famous game against Johann Bauer (1889). The importance of pattern recognition in chess training is brought home for ambitious players and chess teachers working with all levels of students.

There are also compelling columns by Alexander Morozevich, Ivan Sokolov, Karsten Mueller, Wesley So, and an ever changing cast of Grandmasters. These columns are suitable for chess enthusiasts across a wide range of skill levels.

Informants have long had versions compatible with ChessBase, but not all commentary translated well. The image below shows Informant 75/156 in Chess Informant Expert (left) and ChessBase (right). The intended text "with the idea of 17...Rac8, 17...Qa1" is almost unreadable in ChessBase. (readers may click on the image for better viewing).

Side-by-side CI Expert and ChessBase
In the latest versions created especially for ChessBase, such commentary reads perfectly. Below is some text from "Midnight in Moscow: Avoiding the Saemisch by a Less Traveled Road" by Alexander Morozevich. "With the idea" is spelled out, and the figurine algebraic displays correctly.

Informant 122 in ChessBase
I have been a fan of Chess Informants for nearly two decades. My first issue in late 1996 or early 1997 was Informant 64 and it quickly paid dividends in a nice win in a correspondence game (see "Playing by the Book"). In the early years of this century, I started buying electronic editions of Informants and reading them in Chess Informant Reader (CIR). Later, the company came out with Chess Informant Expert, which offered editing and publishing functions not available in CIR. CI Expert also offered a more pleasing interface with options for different color combinations.

CI Expert offers functionality not available in ChessBase. For example, from the electronic edition of the Encyclopedia of Chess Openings, it is possible to jump to reference games in the relevant issue of Informant, as I demonstrated in this YouTube video.

Despite the advantages of reading Informants in their proprietary software, or in print, I welcome these new ChessBase versions. Designing Chess Informant publications specifically for ChessBase software makes Informants more accessible.
