Chengdu, a rainy September evening. I reopened a game of my own from the previous winter — a Petroff Defence that I lost in nineteen moves. Nothing dramatic happened in that game. The seventeen-year-old boy facing me on the online platform did not produce a single combination worth applauding. He just waited. Traded pieces. Simplified the position. By move nineteen, I realised I had run out of ideas long before the game had formally ended.
The board never lies; we are the ones who deceive ourselves with applause. The applause in my head that night was the belief that I was playing actively, that I was attacking, when in truth I was only pushing pieces toward a wall that had been built from move two onward.
I tell this story because last week, reading ChessBase's August product roundup — published on September 13, 2026 — I saw the name Petroff surface again. Not in a game, not in a tournament, but in a database update listing. I sat quietly at my screen for a while, thinking about how an opening system can shape the entire way a person thinks about chess.
An August With No Tournament
That piece did not tell anyone's story. It contained no competitive results, no Elo ratings, no rankings, no victories. That is the first thing I need to state clearly, because there is a labelling confusion in the source material: the header reads "chess historians meet in Copenhagen," while the actual content is the August product roundup. The two are unrelated. I chose to analyse the real content — the product listing — because that is the part that can be verified.
ChessBase publishes these roundups on a monthly cycle. August brought a range of new products spread across several thematic groups: opening database updates, courses on positional play, and courses on calculation and strategic decision-making. This is the familiar rhythm of the training-content market — a steady monthly treadmill designed to retain paying users.
The first thing worth noting is the human structure. Three authors are named: Bahne Fuhrmann, Andrew Martin, Kostya Kavutskiy. Andrew Martin is an English International Master whose name has been attached to this product line for years. Kostya Kavutskiy is an American International Master, active as a commentator and content author. Placing three names side by side in one release cycle is not accidental. It is a strategy to cover several audience groups at once — beginners, club players, and those with a foundation who want to go deeper into specific skills.

I have spent most of my career in commentary booths, where I see a game before it is written down. But there is another kind of chess I have also followed for forty-one years: the chess that is sold, packaged, split into lessons, data packs, and courses. It is loud in a different way from a stadium crowd, and sometimes it is frighteningly quiet.
Petroff and the Art of Promising Nothing
The Petroff Defence begins with 1.e4 e5 2.Nf3 Nf6. Four moves only. But within those four moves lies a clear declaration: White, having opened with the king's pawn, will not be granted free initiative.
The name is tied to Alexander Petroff, a nineteenth-century Russian player. The core idea is simple: instead of defending the e5 pawn passively, Black attacks the e4 pawn immediately. If White rushes to drive the knight away, the position can drift into repetitions — Black can repeat the position to seek a draw if desired. That is why Petroff has a reputation as the system loved by those who want to neutralise the position, and the nightmare of those with only one plan.
I remember an old story. In the early 2000s, when I still worked in tournament organisation, a young player came to me after a loss. He was angry because his opponent had "played ugly" — played Petroff, simplified, then agreed a draw. I asked him one question: if a legal opening system can take away your joy of attacking, is the problem the system, or the fact that you only had one plan?
He did not answer. Years later, he became one of the positional players I respect most.
The fact that a Petroff database was updated in the August cycle says something about the nature of opening theory in the computer age. In the engine era, an opening is no longer a list of fixed variations for humans to memorise. It is a living entity, refreshed continuously as analytical tools find small improvements — moves whose value sometimes lies only in the fact that they have never been played. People call these novelties. An updated Petroff database means there are still people paying to know the newest moves in a system everyone assumed was exhausted.
That is where I want to pause. Petroff is one of the most stable openings in all of chess theory. It is not where people look for drama. But precisely because it is stable, it is where the smallest differences carry the greatest value. In a system where every move has been analysed to the end, novelty survives only in the corners the engine has not yet illuminated. And those corners are a commodity.
I once spent a month reviewing seventeen recordings after a collapse at a major event, and what I learned was not a specific opening variation. I learned that opening knowledge without structural understanding is just a pile of memorisation, and memorisation is never enough when your opponent can play a move you have never seen. An updated Petroff database, then, is not merely a product. It is a reminder that in modern chess, knowledge must be maintained like a machine.
Two Positional Courses and the Question of Overlap
The second thing that caught my attention in the listing was the appearance of two courses on positional play in the same cycle. Two. Not one.
In a mature content market, releasing two products on the same theme in one month can mean two opposite things. It can signal depth — the publisher believes the theme is large enough to serve multiple skill levels. But it can also signal internal erosion, where products compete with each other within the same catalogue and split an already limited customer base.
I do not have enough data to claim this is genuine overlap. But I have enough experience to recognise a pattern. When a major publisher expands its catalogue horizontally rather than vertically, it is often a sign of pressure to maintain release cadence. The month-after-month treadmill demands new content, and sometimes new content is generated to fill a gap in the schedule, not a gap in the learner's knowledge.

Positional chess is a fascinating subject because it is hard to teach. Unlike an opening variation — which can be presented as a sequence of moves with clear evaluations — positional chess requires the learner to change how they see. It is not memorisation; it is learning to feel. A good positional course does not teach you which move is correct, but how to ask questions about a position. And that kind of knowledge cannot be conveyed by a product listing alone.
I remember the feeling of sitting in an empty tournament hall after everyone had left, alone with the pieces on the board. No clock, no spectators, no murmuring. Just the position and the question: what should the next move be? That is the essence of positional chess — a dialogue between you and a position that says nothing.
Two courses on the same subject are not necessarily wrong. But they raise a question any buyer should ask themselves: am I buying knowledge, or am I buying the feeling that I am improving?
Calculation, Decision-Making, and Segmentation by Skill
The remaining product group — courses on calculation and strategic decision-making — belongs to a different category. These are transferable skills, tied to no specific opening. They promise to improve how you think in every game, regardless of what you open with.
This is the most interesting intersection between the two halves of the training-content market. One half sells opening theory — knowledge with an expiry date, needing constant updates. The other half sells skills — knowledge that is more durable but harder to package. Publishers serve both halves because both have buyers.
The way these products are segmented by playing strength says a great deal about market strategy. Aiming at "different playing strengths" is not merely a pedagogical choice; it is a statement about the target customer base. A product for everyone is a product for no one specific. But in the content market, it means the market is reachable — and that is the number that matters more.
I have watched this model shift over many years. When I began my career as a chess player and tournament organiser, chess knowledge was transmitted mainly through books and through actual games. Today it is transmitted through video, through interactive exercises, through downloadable and updateable content packages. This shift has created opportunity for millions — but it has also turned knowledge into a product chain that learners must continuously consume to feel they are not falling behind.
The authors of these courses describe their method as combining theoretical explanation with annotated games and practical exercises. This is the standard pedagogical triad of the modern training market — a formula proven over years. It works. But that formula also means that different products within the same catalogue often look more alike than different.
The Contrarian Angle: When the Seller Writes the Review
Here I need to address something the product listing does not state, but which matters more than any technical detail.

This review article was published by ChessBase itself. The product publisher is also the product reviewer. The photographs in the piece are credited to ChessBase. The tone is supportive, positive, describing the products' value in the manufacturer's own language.
That is not an accusation of fraud. It is simply a structural observation. In sports journalism, I have encountered a milder version of this problem many times: articles about a football club sponsored by that very club. They are not necessarily wrong. But they always lack one thing — the possibility of independent verification.
When the publisher and the reviewer are the same entity, every quality claim becomes part of marketing. That does not mean the product is poor. It simply means we have no way of knowing how good it is if we rely only on the seller's word.
I have been in that position — behind a microphone, talking about a match whose result I already knew, describing moments as if everything were still open. That is a skill. But it is also a conditional form of honesty. I always reminded myself that my voice on air must never become an advertisement for something I had never tried.
Failure is not an own goal; it is when we see the goal clearly and still shoot wide. In this case, the goal is transparency about sources. And I am not certain that review was aiming at it.
There is a specific market risk hidden behind this structure: the pressure to maintain a month-after-month release cadence can lead to prioritising quantity over quality. A mature content market, where users pay for a continuous product line, creates an incentive to favour regularity over breakthrough. And when breakthroughs become rare, buyers gradually learn to distinguish between products that make them improve and products that make them feel they are improving.
The Silence Between Release Months
When the stands are empty, I hear the match whisper in another language. I wrote that line in 2026, when every stadium fell silent and I had to relearn how to listen to chess without the sound of people. In the world of training content, the silence between release months does not exist in that way. There is always a new product. Always an unexplored theme. Always a reason to keep consuming.
That is why I believe today's chess learner needs a skill my generation did not have: the ability to be selective. In a market where everything is available, value lies not in owning much but in understanding deeply. A person can buy every course in the world and still not improve a single Elo point, because understanding is not downloaded — it is built.
Across thirty-two years of commentating classic finals, I learned that the most beautiful moment in a game is often not the decisive move. It is the silence before that move is played — the moment when the player sees something the audience does not yet see. The modern training-content market rarely allows that silence. It fills every gap with a new product, a new course, a new update.
I do not oppose convenience. I oppose substitution. When learning is replaced by consumption, the learner loses the ability to sit quietly before a position and find the answer alone.
What Remains After Reading the Whole Catalogue
The August catalogue ends like every other catalogue — no conclusion, no afterglow, just a list. But one detail stayed with me: the Petroff database update. Out of the entire catalogue, that was the only point of contact with genuine opening theory, and it reminded me that Petroff is still alive. There are still people playing it. Still people studying it. Still people paying to know the latest about it.
That makes me think of the seventeen-year-old boy from Hangzhou who beat me in nineteen moves by promising nothing. He probably did not buy any Petroff course. He simply understood it. And in chess, understanding always beats memorisation.
From keyboard to pitch, the speed of words is never as fast as the speed of the pieces. But the distance between a learner and an understander is not measured by how many products they own. It is measured by how many silences they can endure while sitting alone before a position that has no answer yet.
A match without spectators is still a piece of music, played only for one's own ears. An updated opening database is still a piece of music, played only for a market that is listening. And the final question, the one no one in that catalogue asked, is: as all the future Augusts pass by, as that treadmill keeps turning, are we becoming people who understand chess more, or merely people who consume chess better?
In 2026, I thought I was stepping onto a stage. It turned out I had only entered a corridor. After July 2026, I understood that humility is also a strategy. And in a content market where everyone is confident their product is the best, that humility is perhaps the only opening no publisher can sell.
