ChessBase Endgame Academy: Karsten Müller and 25 Years of Turning Endgames into a Training System

In August 2026, ChessBase announced a new edition of its Endgame Academy, opening with Karsten Müller's Checkmate & Pawn Endgames course. The announcement came without a press conference, without a grandiose advertising video. Just a small line in the subtitle: "25 years ago." For outsiders, it was a harmless footnote. For those who have followed elite chess for three decades, it was a milestone — a full quarter century since the German chess software company began hosting Müller's endgame lectures on its platform.

I became interested in chess endgames for an unrelated reason. In 2026, when every football league in the world was suspended by the pandemic, I sat down to digitize 2,400 old matches from paper notebooks. While the spreadsheet was running, I reopened games by Capablanca and Botvinnik. What astonished me was not the brilliant combinations, but the dry endgames — where an advantage of a quarter-pawn, a single square, a waiting move, could decide everything. That was when I understood why Karsten Müller matters so much.

Everything on the chessboard is data waiting to be read — if you are willing to sit down. Müller has been sitting down for 25 years. And this edition of the Endgame Academy is the first time he has sat down alongside a young architect, an obscure trainer from Hamburg named Michael Kotyk.

Context: From the reading room to the digital platform

ChessBase is not a startup. Founded in 2026 in Hamburg by Frederic Friedel and Matthias Wüllenweber, the company created one of the world's largest chess game databases, along with the Fritz engine and a range of analytical tools used by both the chess world and professional coaches. Over more than three decades, ChessBase has become a kind of "infrastructure" of modern chess — something you don't see while watching a game, but that is always present backstage.

Karsten Müller was born in 2026, a German Grandmaster with a doctorate in mathematics. But his reputation does not come from elite tournaments; it comes from endgames. He is considered one of the world's leading endgame experts, with works such as Fundamental Chess Endings (co-written with Frank Lamprecht), How to Play Chess Endgames, and a steady column of endgame analysis published on international chess platforms. In coaching circles, the phrase "nobody understands endgames better than Müller" appears so often that it has become almost a default — though it remains a promotional statement.

According to data published by ChessBase News on August 14, 2026, the new product launches as an updated edition of the Endgame Academy, with the Checkmate & Pawn Endgames course serving as the opening. This is a deliberate choice. In chess, good endgames and checkmate patterns are the two most fundamental building blocks — unglamorous, ignored by the media, but the place where an advanced amateur is distinguished from a player who truly understands chess.

Müller has collaborated with ChessBase since around the early 2000s. The number 25 in the title is not random. It is both an anniversary and a commercial statement: this product has depth, and that depth has an owner.

Core: Why endgames need a system, and why that system is so valuable

To understand how significant this edition of the Endgame Academy is, it must be placed in the context of how the chess education market has changed over the past two decades.

First, the shift from passive content to interactive content.

In its announcement, ChessBase emphasized that "interactive options have become indispensable in video courses." This sounds obvious, but it actually contains a confession.

For more than a decade, the most popular model of chess course remained video: a Grandmaster sits at a chessboard, analyzes a position, occasionally pauses to ask a rhetorical question. Students watch, nod, and forget most of it. Research on active learning in the e-learning industry has shown that retention rates after passive viewing are typically low, while retention increases significantly when learners must make their own decisions and receive immediate feedback.

Chess is one of the subjects most suited to the interactive model. Every position is an open-ended multiple-choice question. Every learner move can be compared with the engine's move. This is where ChessBase, with its Fritz analysis engine and its vast database, has an absolute advantage over competitors. But a technical advantage only has value when the content inside is good enough to exploit it.

And that is where Müller comes in.

Second, the specialization of the expert.

In the chess world, most famous Grandmasters provide content spanning multiple phases: opening, middlegame, endgame, strategy, tactics. They are generalists. Müller is different. He chose a narrow territory and dug deep into it for decades. This is a rare strategy in the chess education market, and it creates clear brand differentiation.

I have said before that football and chess share the same principle: narrow specialization usually creates higher value than broad generality. A team that excels at defensive counter-attacking can beat a more complete team that lacks a distinctive weapon. Müller is precisely ChessBase's distinctive weapon in the endgame segment.

But specialization also has limits. It narrows the potential audience. A beginner might be overwhelmed by a deeply specialized endgame course, while a club player at an intermediate level needs exactly that. This is the positioning question ChessBase must answer: who are they targeting?

The answer may lie in the appearance of Michael Kotyk.

Third, the role of the coach as a validation channel.

According to ChessBase, the new product was evaluated by Kotyk — a young Hamburg coach — through a "magnifying glass." This phrasing is more notable than it appears. In a product announcement released by the vendor itself, including a third-party reviewer creates a thin layer of validation. Kotyk is not a famous grandmaster, nor an independent critic. He is a young coach working with students — and that is precisely the point.

Chess coaches are the most important purchasing decision-makers in the education segment. They do not buy only for themselves. They buy for their students, and they recommend to parents and colleagues. A positive review from a young coach, who is in daily contact with the new generation of players, has far greater marketing value than an advertisement in a magazine.

However, Kotyk's independence remains unverified. Whether he is a commercial partner of ChessBase is not stated in the announcement.

Fourth, the curriculum structure and its implications.

Choosing the Checkmate & Pawn Endgames course as the starting point has clear pedagogical significance. In chess training theory, pawn endgames are the foundation of all other endgame technique. Checkmate patterns are the most basic building blocks of tactics. A program that begins with the smallest bricks suggests a program designed for gradual progression, from beginner to advanced.

But one thing is worth noting: this structure also means it will be a long-running, multi-volume program. ChessBase may be building a complete learning path — and that means users will have to commit long-term, in both time and money.

Fourth (continued), the economics of chess education in a context crowded with free alternatives.

While ChessBase develops paid, structured courses, a substantial share of the chess education market remains free. Lichess offers free endgame exercises with no paywall. Chess.com offers basic lessons within its free tier. YouTube is flooded with endgame analysis videos by top grandmasters, entirely free and in some cases of very high quality.

This raises a question ChessBase must answer with product rather than advertising: why should users pay for Müller's endgame content when they can watch high-quality free lectures elsewhere?

The answer may lie in a combination of four factors: Müller's authority, the tight structure of the program, the interactivity of the platform, and integration into the ChessBase ecosystem. But that combination only has value if the price is reasonable — a factor not revealed in the announcement.

Transfers are the only place where people pay for hope and then blame time. In the chess education market, the same thing happens: learners pay for a course hoping to get stronger, and then blame their own motivation when results do not come. This is a psychological rule that every education provider exploits, whether unintentionally or deliberately.

Fifth, ChessBase's ecosystem moat.

One aspect rarely mentioned in public discussions is the role of the Endgame Academy as a retention tool. If courses are fully accessible only through ChessBase software or the ChessBase app, buying a Müller course creates an incentive for users to stay within the ecosystem rather than switch to competing platforms.

This is a smart and common business strategy. Major technology platforms use it. But it has a downside: if users do not want to commit to the entire software suite, they may be locked out of the market, even if they only want a single endgame course. In an era of increasingly constrained finances for chess learners, this could be a significant barrier.

Sixth, a larger question about the value of endgames in the computer era.

One of the biggest changes in modern chess is the dominance of the analysis engine. Engines like Stockfish, Leela, and others have reached a level of play far beyond humans. In such a context, is learning endgames through Müller's traditional method still necessary?

The answer is yes, but for a different reason than before. Learning endgames is no longer about finding the precise move — engines do that better. Learning endgames is now about understanding principles, recognizing patterns, developing positional intuition, and learning to make decisions when no machine is available. This is a change in purpose, and it keeps courses like Müller's valuable, perhaps even more so.

In other words, once machines have finished the computation, humans need to learn the understanding. And that is exactly the role of an endgame expert like Müller.

Seventh, the succession problem — when "classic" becomes a burden.

In the announcement, Müller's earlier courses are called "classic." This is a nice word, but it also carries an implication. A product called classic usually means it has existed for a long time, that it has been recognized, and that it may no longer be innovative.

The question is whether this edition of the Endgame Academy is a refresh of interface and format, or whether it truly contains new content. ChessBase does not disclose this. But the way they emphasize interactivity and the participation of a young coach like Kotyk suggests they are trying to renew the product rather than merely reissue it.

If that is true, it is a reasonable strategy. But it also raises a question about over-reliance on a single author. The entire endgame segment of ChessBase is being built around Müller. He is 56 in 2026. Building a product category around a single expert creates clear succession risk in the long term.

Contrarian angle: The interactive revolution may be only a minimum requirement

There is a second reading of ChessBase's announcement. Rather than a statement of innovation, it can be read as a confession that the product has fallen behind.

Look at the competitive landscape. Chessable popularized the concept of MoveTrainer — a spaced-repetition training system where learners must actively replay moves until they are burned into memory. This is a fully interactive model. Lichess offers free endgame exercises with immediate feedback. Chess.com has built a structured lesson system with specially designed interactive exercises.

Against that backdrop, ChessBase's statement that "interactive options have become indispensable" does not sound like a step forward, but like a catch-up move. It may be a confession that for years, their video courses were considered outdated compared to newer competitors.

This does not diminish the product's value. But it recalibrates expectations. Users should understand that they are buying a product with content depth and author authority, not a technology innovator.

The chess game does not create the endgame; it only unmasks those pretending to understand endgames. And in the same way, the market does not create educational quality; it only exposes where educational quality is still insufficient.

Contrarian angle (continued): Endgames may no longer be the decisive skill

Another counter-intuitive reading of this launch concerns the role of endgames in contemporary elite chess.

In the 2010s and 2020s, elite chess underwent a clear shift toward openings. Computer-based opening preparation has become so deep that top-level games often enter balanced, dry positions as early as move 15 or 20. In many cases, games end in draws without ever touching a complex endgame.

If that is true, then deeply learning endgames — however high its quality — may no longer be the decisive skill at the elite level. It remains necessary, but it is no longer the differentiator between top players as it once was.

However, there is a strong counterargument. At the club and amateur level — where most of ChessBase's course buyers sit — the situation is entirely different. At that level, games frequently reach endgames, are frequently decided by basic endgame errors, and frequently end with results that a bit of endgame knowledge could completely change.

This means that the true market of the Endgame Academy is not elite players, but the millions of amateur chess players worldwide, who play weekly and often lose endgames they should win, or draw endgames they should win.

For this group, an endgame course from an expert like Müller could be one of the most effective investments they can make in their chess progress. That is a genuine strength, and it does not require a technological revolution to create value.

Contrarian angle (conclusion): Promotional value lies in scrutiny, not in claims

The most notable thing about ChessBase's announcement is not what they say, but what they do not say.

They do not talk about price. They do not talk about course length. They do not talk about the number of exercises. They do not say what the interactivity specifically is — whether it is exercises embedded in video, a spaced-repetition system like MoveTrainer, or something entirely different.

The absence of this information in an official product announcement is a signal worth analyzing. It may simply be a communication strategy that reserves details for later steps. But it could also indicate that the product's core value lies in Müller's authority, not in technical features.

In either case, the prudent buyer should seek independent reviews, preview videos, and pricing information before deciding. A good product will withstand scrutiny.

Ripple effects: From Hamburg to the practice rooms of young players

To fully understand the impact of this product, one must look at how it spreads through the chess value chain.

Upstream, the Endgame Academy strengthens ChessBase's position as an authoritative provider of educational content. This is a position the company has built over decades, and adding a new course from Müller maintains that momentum.

Midstream, the product adds a new tool to the toolkit of chess coaches. People like Michael Kotyk — young coaches working with students weekly — are the most important end users. They not only use the product themselves but recommend it to students, parents, and colleagues. A positive review from this group can generate significant ripple effects.

Downstream, the impact on amateur players is indirect but potentially large. If an endgame course helps a club player improve their results in weekly games, that impact can spread to the entire club, to local tournaments, and to the next generation of players.

This is a slow, quiet impact, hard to measure. But that is exactly how good educational products change the chess world. They do not create media shocks. They create change at the individual level, and that change accumulates over time.

What to watch in the coming months

There are several signals to monitor to assess the real impact of this product.

First, the announcement of price and access model. If the price is too high relative to competitors, the product will be limited to a narrow user segment. If the price is reasonable and accessible across platforms, it can reach a broader audience.

Second, the appearance of independent reviews from respected coaches and players. If these reviews are positive and not from ChessBase commercial partners, that will be an important validation.

Third, the response of competitors. If Chessable, Chess.com, or other platforms announce similar endgame products at competitive prices, the market will become more vibrant, and consumers will have more choices.

Fourth, the number and quality of subsequent courses in the Endgame Academy. If this is a long-running program with multiple quality courses, it will create a complete learning ecosystem. If it is a single product, its impact will be more limited.

Conclusion: When an expert grows old, and a new generation must learn again from the beginning

I no longer believe in miracles on the chessboard; I only believe in the conversion rate of advantage. And in the case of the ChessBase Endgame Academy, that rate depends on two variables: the true quality of the content, and the true accessibility of the price.

Karsten Müller will not stay young forever. At 56 in 2026, he is at the peak of his teaching career, but he cannot sustain it forever. In twenty years, the chess world will have to face a difficult question: who will succeed him as the endgame expert? Will a new generation of specialists be trained, or has narrow specialization like Müller's become too hard to reproduce in a world where young players are drawn to the speed and glamour of fast chess formats?

This is a question without an easy answer. But it is worth asking. Because when an endgame expert departs, a piece of chess knowledge — knowledge that cannot be replaced by any engine — may depart with him, unless it is passed on to a next generation.

Esports and elite chess differ only in the screen; their operating systems are identical. Both rely on transmitting knowledge from person to person, from generation to generation. And when a transmission system is structured correctly — as Müller is doing with the Endgame Academy — it can outlast any individual.

That is worth watching over the next 25 years.
