Karsten Müller and the Transformation of Endgame Art on the Digital Chessboard

In the small room in Nha Trang, I opened my notebook from 2026. The pages had yellowed, but the handwriting remained remarkably clear: "King and pawn, nothing more to say, only the truth." That was my record of an endgame played by Karpov at the Linares tournament. Thirty-three years later, sitting before a computer screen, I read the news that ChessBase had released a new edition of Endgame Academy, featuring endgame courses by Karsten Müller. Every stadium I have walked through holds a secret door, and the entrance is always a person. For chess endgames, that door bears the name Karsten Müller. Across three decades of commentating on chess for VTC, I have watched how people study endgames transform from printed books to CDs, and then to online platforms. But one truth remains: finishing a chess game has never been easy to teach, and never easy to learn.

On the surface, this event looks small to outsiders. An online learning platform, a chess course, a name that does not hold a world championship. But for those who follow chess in Vietnam — where we have players who have put Vietnamese chess on the Asian map — the story of Karsten Müller's endgame curriculum carries an epochal weight.

Karsten Müller was born in 2026 in Hamburg, in the Federal Republic of Germany. He is not a world champion, nor a super grandmaster with a peak rating. But within the international chess world, he is regarded as the foremost authority on endgames. His "Endgame Corner" columns on ChessBase have run for hundreds of continuous issues. His endgame books are used as training curricula in multiple national chess federations. Among professional trainers, the phrase "nobody is better at endgames than Karsten Müller" is a statement repeated by many grandmasters as a professional fact.

ChessBase has been the world's leading chess software company since 2026, headquartered in Hamburg. Endgame Academy is their structured learning platform, and this new edition introduces Müller's courses on "Checkmate" and "Pawn Endgames" — the two most foundational topics of endgame theory.

What deserves attention is how the timing is framed. The article's headline references the marker "25 years ago." That is an anniversary approach, possibly marking 25 years since Müller began collaborating with ChessBase, around 2026. But it also raises a question about how genuinely new the product is. When a vendor uses the word "classic" to describe its own content, readers need to read between the lines.

When analyzing this product seriously, three technical aspects deserve scrutiny.

First, the shift from passive to interactive learning. ChessBase's announcement states clearly: "interactive options have become indispensable in video courses." ChessBase is not the first to move in this direction — it reflects a global e-learning trend. Studies on online education over more than a decade have shown that learners retain knowledge better when they must actively solve problems rather than passively listen to lectures. In chess, this is especially important: endgames are a field where dry theory is not enough. Learners must calculate with their own hands, make their own mistakes, and correct themselves.

As someone who has commentated on chess for over three decades on VTC, I remember how different my generation's learning was. In 2026, to study endgames, we had to copy games from books, physically set up positions on a wooden board, and analyze on our own with no computer assistance. A single endgame session stretched three hours just to grasp one pawn-push technique. Today, software can display every variation, point out mistakes instantly, and let learners try moves immediately. The difference in learning speed is enormous, and that is a positive thing.

Second, the "classic product" strategy and the question of genuine innovation. ChessBase calling Müller's courses "classic" signals accumulated market validation — they have sold these products for years and they have been accepted. But "classic" can also mean old. If the new edition is merely a refreshed interface with interactivity added to existing content, that is marketing, not innovation. Loyal ChessBase users, those who have bought Müller's courses before, may feel they are buying back something they already own.

Third, curriculum structure and depth remain undisclosed. The announcement says the course "kicks off" with "Checkmate and Pawn Endgames" — meaning this is the first phase of a broader program. But the number of exercises, hours of content, and pedagogical progression are not published. A thin course with interactive features is not necessarily better than a comprehensive video series. This is something buyers must verify for themselves before deciding.

The chess education market has been reshaped by free alternatives. Lichess, with its free endgame puzzles, has millions of users worldwide. YouTube offers countless high-quality endgame tutorials from grandmasters. Chessable has moved ahead in integrating interactivity into grandmaster courses. ChessBase is no longer the only option.

But one advantage ChessBase still holds: its ecosystem. Users of ChessBase software — hundreds of thousands worldwide, including many coaches and professional players in Vietnam — can access these courses directly within an environment they already know. This is the "ecosystem moat" strategy: keeping users inside the platform instead of letting them buy standalone courses elsewhere. As competition intensifies, this is a smart move.

Michael Kotyk and the role of the young reviewer. The announcement introduces Kotyk, a young chess trainer in Hamburg, as someone who has "scrutinized" the product. This is a subtle tactic: instead of merely advertising from the vendor, they include a "review" from a professional trainer, creating an appearance of independence. But readers should ask: is Kotyk truly independent? Is he a ChessBase partner? A review from someone chosen by the vendor is not full independent confirmation.

The counterintuitive angle here is this: focusing on the product's interactivity may obscure a larger pedagogical problem. In academic chess, there is a famous paradox about endgames.

Computers have made everything easier in endgame study — but they can also make learning more shallow. When you have a tool that instantly shows the correct move, you tend not to calculate for yourself, not to wrestle with the position. That very struggle — the pain of sitting for hours before a position, wondering which move is right — is where endgame skill is truly born.

An empty stadium, but the applause of 2026 still echoes in every old record. In chess, the solitary endgame training room resembles that empty stadium — where future victories are prepared, without spectators, without scores, without instant feedback.

An interactive course, no matter how well designed, risks becoming a form of "digital rote learning." Learners answer exercises correctly, receive high scores, but never confront the deep silence of an empty board — where there are no hints, no instant feedback, only the learner and the position.

At 65, with nearly half a century of chess commentary, I believe this deserves to be said: technology can accelerate learning, but it cannot replace patience. In endgames, patience itself is the skill.

This does not mean Endgame Academy lacks value. It has value. But it is a tool, not a miracle. And like any tool, it is only good when used correctly.

A record is never old, it is only waiting for someone who knows how to listen. That holds true for endgames from a century ago, and it holds true for lectures digitized today.

If Karsten Müller — regarded as the greatest endgame authority in chess — chooses to refresh his lectures through interactive technology, that signals the chess education industry is entering a new phase. But chess learners in Vietnam, from a boy in Nha Trang to a coach in Hanoi, should remember one thing: no technology can replace sitting before the board, silent, and wondering. The patience of 2026 is the same as that of 2026. Only the board is different.
