ChessBase Magazine #225: 27 Miniatures from Prague and How a Training Magazine Curates Its Own Sample

The game ended on move twenty-one. The loser still had thirty-eight minutes on the clock, and no move had been blundered in any obvious way. In the VTC commentary booth I had twelve minutes to explain why a game of chess could finish that early. That was 2026. I had just moved from playing and organising tournaments into the commentary chair. I remember saying something clumsy: the loser did not get a single move wrong, only the order wrong. The producer in my earpiece asked me to hold the air for three more minutes, because the audience liked hearing about short games.

That night I understood something I would only be able to name much later: a miniature is not a game with no content; it is a game whose content arrived too early for the opponent. From the next day I kept a notebook, logging every game I ever commentated, with exactly one column: the reason it ended. Fourteen years later, when I saw the line 27 highly entertaining miniatures in the contents of ChessBase Magazine issue 225, I opened that notebook before reading anything else in the magazine. Professional habit: when you meet a data set someone else has already curated, the first question is who curated it, and by what criteria.

Some magazines are built like a curriculum

Issue 225 leads with the Prague analysis: Aravindh Chithambaram, Anish Giri, Ediz Gurel, David Navara and several others annotating their own games from the Chess Festival Prague 2026. Then comes the special section with 27 miniatures chosen for entertainment value. After that, a block of opening videos by Jan Werle, Daniel King and Robert Ris. It closes with ten opening articles presenting new repertoire ideas. The magazine ships in two forms: a direct download including a PDF booklet, or a printed booklet posted with a download key. This issue also comes as a ChessBase Book for iPad, tablet and Mac.

ChessBase is the German chess software publisher, operating from Hamburg since 2026, best known for its game database and the Fritz interface. Its magazine has passed two hundred issues, meaning nearly four decades of material edited under one philosophy: players explain their own games, opening specialists update trends, and trainers teach middlegame, strategy and endgame technique.

For a Vietnamese reader, the names should be placed side by side. David Navara has been the Czech number one for nearly two decades, known for precision and impeccable manners at the board. Anish Giri is the Dutch grandmaster of Nepali origin, long a member of the world elite, famous for keeping the balance. Aravindh Chithambaram belongs to India's next generation. Ediz Gurel is a young Turkish grandmaster. Among the trainers, Jan Werle and Robert Ris are familiar names in opening video production, while Daniel King has been making instructional chess video for decades.

The interesting part is not the list of names but the structure. A publication built as an ordered curriculum is different from an attachment to a news bulletin. The editor must decide in advance what to teach, to whom, and in what sequence.

The setting deserves a paragraph too. Prague hosted the fourth Chess Olympiad in 2026, and the Czech lands are one of the old cradles of European chess. An international tournament held there carries a different weight from a purely commercial invitational: the local audience knows the game, and the players have to perform in a hall that can see. That is the backdrop against which the analysis in issue 225 stands.

27 miniatures, two filters, and a set without a denominator

The number 27 should be read alongside a question about thresholds. In chess analysis practice, a miniature is usually understood as a game finishing within twenty-five moves; some take twenty, some take thirty. The threshold determines the composition of the set. Set at twenty moves, you mostly catch opening disasters. Raise it to twenty-five and you start catching games where a piece got trapped. Push it to thirty and you reach games with genuine middlegame attacks. Those three sets teach three different lessons, even though they share one name.

Then comes the second filter: entertainment. The editors did not simply choose short games, they chose good short games. So the set has been sifted twice, once by length and once by taste. The 27 miniatures are not a report on the Prague festival; they are a collection selected by the editors' aesthetic criteria, and those criteria are the thing most worth reading. When you know what people select, you know what they believe learners need.

In my notebook, the causes of a miniature fall into three groups. The first is opening-related: the opponent deviates from theory on move eight to twelve, and the other side has prepared exactly that line. The second is middlegame-related: a sequence of exchanges is miscalculated, usually because the position of a minor piece was misjudged, a knight sitting on a square with no way home. The third lies off the board: time budget, psychological state, the residue of an earlier game that same day. These groups demand three completely different kinds of training, and this is where a miniature collection can mislead: it gathers all three into one place and makes us think they are the same thing.

I must state the limits of the numbers I am using. My notebook includes blitz and rapid, not only classical chess, so its rate of short games runs far higher than a classical tournament would. Taking only my two years as a commentator, I recorded around one hundred and sixty miniatures, more than half of them in the opening group. That is one person's statistics, not the chess world's. But it is enough to stop me from ever reading a miniature collection the way I read a news report.

There is a historical shift worth noting here, and it distinguishes the classical miniature from the modern one. The three most famous miniatures in history, Anderssen beating Kieseritzky in 1851 in twenty-three moves, Anderssen beating Dufresne in 1852 in twenty-four moves, and Paul Morphy's Opera Game in 1858 in seventeen moves, were all decided by an attack on the king. The miniature of that era was the reward of a brilliant attacker. The elite miniature today is usually decided by a trapped piece or a positional squeeze. Early finishes changed hands: from the attacker to the more patient player. Anyone reading the 27 miniatures only for beautiful combinations will miss most of the lesson.

Ten opening articles and the speed of theory transfer

Opening articles are the shortest-lived part of any such magazine, and also the part most likely to create illusions. Fifteen years ago, a new idea appeared at a major event, reached the database months later, and reached the amateur player a year after that. Today a new line can travel from a board in Prague to online blitz games within days, and to your club within weeks. That distance has been compressed, and what remains valuable in an opening article is not the move but the explanation: why the line works, which structural features it depends on, and what the opponent can do to make it collapse.

That summer in the V-League I learned one thing: a formation only looks beautiful while the opponent agrees to stand still. In chess that reads: an opening line only looks beautiful while the opponent agrees to enter it. A database tells you how many times people entered it and how often they won, but it cannot tell you whether your opponent next weekend will enter it. That is the part no software calculates for you.

The ten opening articles should be read twice. First, to see what people are arguing about. Second, to ask yourself: can this line survive inside the opening system I actually play, and if I graft it onto an existing repertoire, how many lines must I give up. The answer is almost always that something must go. Every new idea entering a repertoire carries an opportunity cost, and that cost is never printed in the article.

Opening videos: learning speed and the cost of attention

The block of opening videos by Jan Werle, Daniel King and Robert Ris is an editorial decision worth analysing. Text and image do not teach the same thing. Text gives you branching: you pause, look at the alternatives, mark the spot you did not understand. Video gives you rhythm and hesitation: you watch the presenter falter over a move, and that faltering is itself information. In the first hour, video takes you much further. From the second hour on, text pulls ahead, because you cannot search backwards through a twenty-minute video.

Packaging is data too. A direct download with a PDF booklet, a printed booklet with a download key, and a ChessBase Book format for iPad, tablet and Mac all say something about the user: they study in different places, and every time they must open a computer to check a line, they skip it. I have measured myself on this: the time between wanting to look up a game and actually opening it decides whether I look it up at all. The lower the friction, the more learning happens. That is why tablet-readable formats are worth more than they appear.

Limits of the data

A publication like issue 225 tells us that 27 miniatures were selected, but it does not tell us how many games were played at the Prague festival. Without a denominator there is no rate. This sounds minor, but it changes how the material should be used. Without knowing what share of the tournament those 27 games represent, I cannot conclude that miniatures are becoming more or less common. I can only conclude something about the editors' taste.

The same error appears when football fans watch a goals compilation and conclude that every match is thrilling. A compilation is a filter. A season is a whole. I write this section in every analysis I publish, and I write it here too, even though the subject is a chess magazine: data without a denominator should be used for observation, not for conclusions about trends.

There is one more point I want to state plainly, because it concerns the value of this kind of publication. A magazine built on the players' own analysis is a record that can be checked. In a period when the integrity of results is being questioned in several circuits, the value of a clean game explained by the person who played it rises rather than falls. Esports taught me what football hides well: a reaction within two hundred milliseconds can break an entire system. Blitz and bullet are where that speed decides the score, and also where training converts into results fastest. Precisely because it is fast, it needs a slow record to check against. That is where a printed publication still stands.

The contrarian angle: a beautiful collection is one that has filtered out the failures

What troubles me most about the 27 miniatures is not the quality of the games. It is that the collection only tells the story of games that ended early. It does not tell the story of the hundreds of other games that ran to move sixty and that nobody wants to replay. A student who reads those 27 games easily forms a false expectation: that top-level chess is mostly settled within the first twenty moves. The opposite is true: most elite games go long, and those long games are where stamina, endgame technique and patience are measured.

I fell into this trap myself, in a different way. In my early years as an analyst I treated every miniature as a mine of tricks and gathered them into training material. After a few seasons I realised the tricks almost never converted into results. What converted was the ability to notice a piece standing on the wrong square before the opponent exploited it. In other words, the lesson is not on move twenty-one but on move seventeen, the move neither player was still paying attention to.

There is another tension every editorial board lives with. Entertainment content teaches you to wait for your opponent to err. Training content teaches you to wait for yourself to err. Those two goals pull in different directions, and a publication selling both entertainment and training must choose its mix. Issue 225 places the tournament analysis first and the miniatures in the middle, a fairly wise order: the reader has already passed the driest part before reaching the most enjoyable one.

And this, I think, is the nature of every chess publication today. Software produces the best move in under a second. What is scarce is no longer the move but the reason. A player saying why he chose that move, under time pressure, with incomplete information, is something no engine produces. To read 27 miniatures only for the combinations is to use the wrong product.

No tactic is ever old; only the way we read a game expires.

In 2026 I threw away half my old data set, because football after the lockdown was a different sport. In chess, that shock came earlier and more quietly: once online games became the main training ground, the frequency of opening lines diverged sharply from over-the-board play. An idea in the ten opening articles of issue 225 is usable only after you ask yourself: will my opponent next weekend meet this line three times or three hundred, and what have they prepared at home. The same opening line, two environments, two different conclusions.

A counting exercise for the next issue

I suggest one small task after finishing the 27 miniatures: count how many come from the same opening family. If eight of the twenty-seven start from one structure, that is a signal about the season's theoretical battleground, not entertainment. And the second task: keep a notebook of your own, logging every miniature you play in a year, with one column only, the reason it ended. A year later you will hold something more useful than 27 games by other people: your own data, about your own mistakes, in exactly the phases where you collapse most. No tactic is ever old; only the way we read a game expires, even when the board is your own.
