25 Years of Endgames Without an Audience: Karsten Müller and the Quiet Revolution in Chess Education

In 2026, at a tournament hall in Shanghai, I watched two seventeen-year-old players drag each other into a dry endgame: a king, a passed pawn, and a few empty squares each. No spectators, no commentators, no cameras. Just the ticking of the clock. Right then, one of them pushed his pawn one tempo too late and lost three moves later. Three weeks on, that same boy won a national junior event — but the win came from the opening, not the endgame. I have never forgotten that moment, because it exposed a paradox: we teach the opening with thousands of videos, yet we teach the endgame with a few dozen old blog posts. Today, on August 14, 2026, ChessBase announced a new edition of Endgame Academy, opening with Karsten Müller's “Checkmate & Pawn Endgames” course. The news is not loud. No million-dollar deal, no grand press conference. But for me, it marks a turning point worth writing about. Karsten Müller is not a name that shakes rating lists. He has never been world champion. He does not appear on magazine covers. But within chess coaching and publishing circles, Müller is regarded as one of the world's foremost endgame authorities. For more than twenty-five years he has written for ChessBase and Chess Publishing, and maintained the Endgame Corner column — one of the most cited endgame resources in Western training libraries. That journey echoes the road I have walked myself. In 2026 I began as a player and tournament organizer, then moved into chess commentary for VTC for four years. There I learned one thing: the endgame is the most neglected part of the game. Audiences watch the opening because it is fast, beautiful, and predictable. The endgame — where every mistake is punished coldly — is watched by far fewer. The forgotten queens of chess do not wear crowns; they sit at the endgame board, patiently shifting one square at a time. ChessBase understands this paradox well. Endgame Academy is not a brand-new product; it is an existing platform designed to be a miniature “endgame school,” where learners do not merely watch but must solve. The “25 years ago” framing is a device: it celebrates Müller's journey while reminding long-time users that this is the continuation of a legacy. In the chess education market, legacy is worth more than a few new features. The most notable part of the update is how it responds to a shift in online learning. The announcement states plainly that interactive options have become “indispensable” in video courses. This is not a slogan. It is an admission that the passive-viewing model is dead. Today's chess learners want to click, to try a move, to fail and be corrected immediately. Pedagogically, Müller starting with “Checkmate & Pawn Endgames” is a deliberate choice. Pawn endgames are the technical foundation of the entire endgame. Without mastering pawn coordination, a learner stays stuck at intermediate level forever. Checkmate patterns, meanwhile, are the most basic building block of tactical thinking. Placing these two areas at the head of the curriculum shows ChessBase is targeting serious players, not merely curious beginners. It is a commercially risky but technically honest choice. There is one detail I appreciate: the name of the course reviewer. Michael Kotyk — a young Hamburg coach — is described as holding a “magnifying glass” over the product. It is a smart communications move. Rather than letting the producer praise itself, ChessBase borrows a young coach as a voice of verification. But I also note this: Kotyk is a coach, not an independent player; his degree of independence is unverified. As a writer, I always separate Müller's genuine reputation from the marketing packaging of the announcement. Here I want to be blunt with a harder view: the commercial value of an endgame course never reflects its technical value. Müller does not need a best-selling product to prove he is good. If anything, a best-selling product sometimes blurs his real contribution. The value of an endgame specialist lies not in the price tag, but in the fate of players who dare to believe every mistake can be fixed. The chess community is watching a trend: all content must be interactive, must have exercises, must have gamification. That is progress. But it is also a trap. A course with a beautiful interface and eye-catching interactive drills can still be shallow in pedagogical depth. The real question is not whether a course is interactive, but whether its exercises force learners to think correctly. Without information on exercise count, content volume, or rising difficulty, a buyer is purchasing belief in a name. Another risk few mention: chess education is competing with increasingly good free options. Open-source platforms keep expanding endgame puzzles at no cost. The long-term pressure on any commercial product is real. ChessBase retains users largely through its software ecosystem, not only through lectures. That is an advantage, but also a risk of complacency. And there is one thing I have held to for years: the greatest value of courses like this is not revenue, but keeping a layer of knowledge from being lost. When I wrote my first article on chess strategy, it received 120 reads. A small number. But I understood I was filling an enormous media gap. Müller does the same for the endgame, on a larger scale. In the summer of Russia 2026, while the world turned to a different tournament, I too went looking for values that were not on any map. The endgame is the same — it has no map, only a guide. The change is already happening. Chess education is shifting from performance to practice, from viewers to doers. That is welcome, though we still cannot fully judge the true quality of this product. What I want to see next is not another glossy course, but evidence that such courses produce a generation of players who handle endgames better. If that happens, Karsten Müller will be remembered not for twenty-five years attached to a brand, but for teaching a generation that a game does not end when the opening does. In the world of chess, the only boundary is the boundary of skill. No defense can stop a player who has decided to learn every last square on the board.
