Karsten Müller and 25 Years of Endgame Scholarship: ChessBase Launches Interactive Endgame Academy

On August 14, 2026, ChessBase launched a new version of the Endgame Academy — an endgame technique course taught by Karsten Müller, one of the world's leading endgame experts. The product marks 25 years of collaboration between Müller and the ChessBase platform, while signaling a significant shift from passive video learning to interactive formats. Michael Kotyk, a young chess trainer in Hamburg, personally experienced and reviewed the course, providing highly practical assessments for the German and international chess community. Karsten Müller is no stranger to anyone following chess education over the past two decades. He is the author of dozens of endgame books, maintains the Endgame Corner column on ChessBase for many years, and collaborates with Chess Publishing and chessok.com. What makes Müller special is that he is not a top-level competitive player — his reputation is built entirely on analysis. In the world of chess, where grandmasters often juggle coaching and authoring, Müller's absolute specialization creates a distinct brand: the endgame expert. The "Checkmate & Pawn Endgames" course — the opening section of the Endgame Academy — is designed with a rigorous pedagogical progression. Pawn endgames and checkmate patterns are the most fundamental foundations that any player must master. This is a smart strategic choice: rather than starting with complex structures that only attract professionals, ChessBase targets a broader audience — club players looking to improve their foundational skills. Michael Kotyk, 28, a trainer in Hamburg, is the first independent evaluator of the course. In a 45-minute review video posted on his YouTube channel, Kotyk uses the "experience from my match tracking" methodology — his term for an analytical approach based on observations from hundreds of hours of student coaching. "Endgame is where my students lose the most points," Kotyk shared. "But after experiencing Müller's interactive exercises, they start seeing patterns they previously completely overlooked." Kotyk's assessment is particularly valuable as he represents the younger generation of coaches — those who understand both student burdens and parental expectations. However, notably, the article on ChessBase News is purely promotional. Is Michael Kotyk an independent critic or a ChessBase brand representative? The financial and partnership relationships between Kotyk and the platform are completely undisclosed. In the chess industry, where professional players often serve as brand ambassadors for learning platforms, the blurring between honest evaluation and marketing becomes common. This is a blind spot that readers need to equip themselves against. The technological highlight of the new Endgame Academy version lies in its interactive exercise system. Instead of passively watching lecture videos, students are required to make moves on a digital board, compare their solutions with Müller's standard responses, and receive immediate feedback. This is an advancement over traditional courses — active learning methods have been proven more effective than passive learning in educational research. ChessBase asserts that "interactive options have become indispensable in video courses" — and this assessment accurately reflects the broader global e-learning trend. But the question remains: are the interactive features truly excellently implemented or just a technological veneer over old content? ChessBase does not disclose details about the number of exercises, course duration, or specific feedback mechanisms. In the current market, platforms like Chessable have integrated spaced repetition and adaptive learning systems, while Lichess provides a free puzzle library with diverse difficulty levels. Endgame Academy needs to prove that it surpasses these free alternatives — not just with Müller's name but with execution quality. ChessBase's strategy with Endgame Academy extends beyond selling courses. This is a move within a larger ecosystem: retaining users within the ChessBase system rather than allowing them to migrate to other platforms. When a student buys Müller's course on ChessBase, they have incentive to use Fritz software, the ChessBase mobile app, and databases to support their learning. This is a moat business model — increasing switching costs — common in the software industry but particularly effective in the chess market where platform loyalty affects overall experience. The 25-year milestone of Müller and ChessBase collaboration is a heritage message. If Müller began publishing content on ChessBase around 2026, his first generation of students has now grown up — some have become coaches, some continue pursuing chess as a hobby. Republishing with an interactive format is ChessBase's way of saying: "We are not just preserving the past, we are building the future." This is clever marketing storytelling — targeting both nostalgic emotions and progressive expectations. In the online chess market, pressure from free platforms is growing. Lichess, an open-source project, continues expanding its puzzle library and learning features without any financial barriers. Chess.com is heavily investing in courses from well-known grandmasters. In this context, ChessBase needs a reason for users to pay rather than use free alternatives. Karsten Müller is part of the answer — his absolute specialization in endgames creates differentiation that mass platforms cannot easily replicate. But the question of price — currently undisclosed by ChessBase — will determine whether this value proposition is accepted by the market. When I sat alone in my empty office in Saint Petersburg during the pandemic days, listening to the wind whistling through the window, I realized that chess never needed a packed stadium. It only needed the right moves. Müller's Endgame Academy is not for those who want to witness spectacular checkmates on grand stages — it's for quiet players meticulously studying each move on a board in their home office. And perhaps, that is the true majority of chess players. August 14, 2026 marks a new chapter in the chess education story — not through a top-level match, but through an exercise system. Karsten Müller, in his 50s, continues to illuminate a new generation of players the way he has done for 25 years. ChessBase, with its ecosystem moat strategy, bets that the market will still pay for specialization. Only time will tell whether this game ends in victory or stalemate.
