ChessBase Magazine #225: 27 Prague Miniatures and the Data Nobody Rewinds

I heard it before I saw it. A dry, tight click, without resonance — the sound of a wooden knight's base striking a compressed board in a hall in Prague, where Chess Festival Prague 2026 took place. For a sports documentary screenwriter, that click is the equivalent of a stopwatch press: a decision has just been made, and it cannot be recalled. The promotional description of ChessBase Magazine issue 225 — the periodic training publication of ChessBase, the German chess software house — reads very dryly. Games from Prague analysed by Aravindh, Anish Giri, Gurel, David Navara and a few other names. A special section with 27 miniatures. Three opening videos by Werle, King and Ris. 10 opening articles with ideas for refreshing a repertoire. Skimmed, the list looks like an inventory. Read slowly, it is a structured data file, and the structure is what matters. ChessBase Magazine operates as a training journal rather than a news publication. World-class players sit down with their own games and explain the ideas behind the moves. Opening specialists present the latest theoretical trends and options that can go straight into a reader's repertoire. The rest belongs to coaches, covering tactics, strategy and endgames. All three strands serve one goal: making the reader a better tournament player. Chess Festival Prague is an annual chess festival in the Czech capital, gathering international players across several sections, from the elite group to high-rated amateurs. That David Navara — the Czech number one for many years — analyses games from a tournament held in his home country carries its own meaning. He is not commenting on others from a studio far from the board; he analyses games played by himself or by peers of his generation. In my trade, the distance between the person at the board and the person in the commentary seat is the largest distance of all. Before going deeper, a few concepts need clarifying, because the chess world uses them as if everyone understood. A miniature is a game that ends quickly, usually under 25 to 30 moves, with the result already decided. A repertoire is the set of opening lines a player chooses to play regularly, prepared move by move to certain depths, so he does not start from scratch at every tournament. An opening video is a spoken format with an interactive board, letting viewers watch moves run rather than just read notation. On format, issue 225 appears in two shapes. Direct download comes with a booklet in PDF. The second is a printed booklet sent by post with a download key. A notable addition: the issue is also packaged as a ChessBase Book for iPad, tablet and Mac. Buyers receive both print and digital, or choose one, without losing access to the interactive training material. The layer I care about most is the first: players analysing their own games. Aravindh, Giri, Gurel, Navara — four names representing four generations and four schools. When a player explains a move himself, he supplies something no notation can hold: the range of options he considered and then discarded. That is a primary source. Across many years of post-production work on sports documentaries, I have always ranked interviews with the protagonist above any form of commentary. I trust footage over testimony, because footage cannot lie. But I also know its limits: it records what happened, not what was rejected. A game analysed by the player himself is the necessary complement to the visual record, exactly as a post-race interview completes a rough cut. From years of watching chess events and competition footage, I have drawn one rule: the move on the board is data, the reason retold is context, and missing either reduces analysis to entertainment. The 27-miniature section is the most easily underestimated part of the whole issue. The chess world files miniatures under entertainment: pretty, compact, memorable, good for club storytelling. That filing wastes a valuable data source. A miniature exists because someone erred early, and early errors repeat with patterns. If the 27 miniatures were classified by error type — loss of control of an open file, a forgotten combination on a diagonal, a misjudged pawn structure — we would have an error map rather than a pretty anthology. I rewind SEA Games 29 footage to find what others forgot; the principle here is identical. The three opening videos with Werle, King and Ris represent a different mode of transmission. Daniel King is known for a long-running chess video series, slow and clear, prioritising newcomers. Jan Werle and Robert Ris lean toward openings and the resulting middlegame structures. The strength of video is tempo: learners see moves appear in real time, sensing which move is natural and which is forced. Its weakness is also tempo: nobody re-watches a 40-minute video to find one specific opening branch. Hence the need for 10 opening articles alongside. Those ten articles do something else entirely. They turn ideas into searchable text: notation, branches, assessments, editorial notes. For club players, this is the part that genuinely pays. A video can convince you of a line; an article lets you look it up in round four of a weekend event, when you have fifteen minutes of preparation and need to know what move twelve is. Packaging as a ChessBase Book for iPad, tablet and Mac is a quiet but important signal. It shows chess training content leaving the desk for the dead time of a day: trains, waiting rooms, breaks between rounds. When training material sits on the same device as other apps, the quality of the interface becomes part of the quality of the training. A sluggish interactive board kills the urge to study faster than any notation error. The training-content industry celebrates variety. An issue with game analysis, miniatures, video, articles and a mobile app sounds like a perfect catalogue, and it is certainly better than a single-format product. But format variety does not automatically create depth. The 27 miniatures will teach nothing to a reader skimming past them toward entertainment, and 10 opening articles are useless to someone who only watches video. The value of issue 225 depends on the buyer choosing one data layer and digging to the bottom, rather than touching every layer. One more detail deserves noting, and I note it as a data observation rather than an accusation. In the author list given by the promotional text — Aravindh, Giri, Gurel, Navara, Werle, King, Ris — no woman appears. A single promotional line is not enough to judge a whole publication, and I do not make a habit of concluding from one line. But it is data about who gets invited to the analysis table. In 2026, when I proposed exploring Nguyen Thi Oanh's running mechanics at SEA Games 29, a director dismissed it by asking what women know about running. I did not argue. I borrowed the footage, counted stride rhythm on the final lap, and cut a two-minute segment. The lesson from that carries straight over: an author list is not proof of quality, but it is proof of the structure of who gets to speak. A chess culture that hears analysis from only half the population builds theory on half the data. I have hurdled my whole life, I have simply never been timed — and I know the feeling of a correct result left out of the record. For players in Vietnam, the practical value here is a standard for self-testing. You may not buy ChessBase Magazine issue 225, but you can apply the same structure to your own data: record your games, classify errors, group early-finishing games into a separate set, and read that set before the good ones. A collection of 27 quick losses of your own trains you better than 27 beautiful wins, because a loss points exactly at your weakness. The right approach to a publication like this is to choose one layer and dig to the bottom rather than read everything. If I were cutting a film about Prague 2026, I would not open with the best game. I would open with the shortest one, the game viewers think ended too fast to understand. An empty stadium, and I turn the sound of spikes into the heartbeat of the film — with chess, the heartbeat sits at move twelve, where nobody rewinds. Every documentary is a running track: the audience sees the finish, I live at every starting line.
