Before I open a product page, I look for a number. Whatever the headline claims, my first question is whether there is a measured variable inside. August 2026, London Stadium. That was where I was first put in the anchor chair — the Delhi digital platform's first female lead host, and the first time it had tried a presenter instead of a commentator. I opened with a twelve-minute block on start mechanics, then called the 100m final live: Justin Gatlin 9.92, Christian Coleman 9.94, and Usain Bolt 9.95 for bronze in his final individual race. I had counted Bolt's 41 strides in his 2026 world record of 9.58 against Gatlin's 44, and used that difference to explain the gap.
That week, the rule of 'mechanics first, atmosphere later' entered my writing and never left. I stopped opening with emotion and started opening with a measured variable. The producers who wanted emotion got a split time; the viewers stayed anyway.
This piece is a test of that same rule. What I have in hand is a description of a chess-education product: six instructional videos by the Bulgarian coach IM Valeri Lilov, promising a so-called 'anti-system' repertoire for Black. Above it hangs a quote — 'Chess is massively undervalued' — attributed to 'Turlov'. There is a crack between the headline and the body from the very start. And that crack, surprisingly, is the most honest place to begin.
Context: The chess boom and the quiet education market
Chess has seen a boom since 2026, and much of it happened off-camera. The wave came after 'The Queen's Gambit', then daily active users on online platforms jumped, and with them a demand was born — newcomers do not just want to learn the moves, they want to improve. During the pandemic years, calling the empty-stadium IPL and the 30 August Online Chess Olympiad final from a Delhi studio — where India and Russia were declared joint winners at 3-3 after a server disconnection hit Nihal Sarin and Divya Deshmukh mid-match — I began to understand that chess has a structural difference from ordinary sport. Chess has a cheap entry point: the internet, a board, an app. But the ladder of improvement is not cheap, and it is precisely on that ladder that an entire education market stands.
The economics of this market differ from ordinary sport. In football, money moves through transfer fees, wages and broadcast rights; in chess, money moves through courses sold directly to consumers, subscriptions and video series. A club never buys a repertoire course. But an improving amateur player buys exactly that for ten or twelve dollars a month. Lilov's six-video product is therefore not a sudden thing — it is the normal product of a mature market.
The part that interests me is the claim. In marketing language, these White systems are described as 'extremely dangerous'. That one word — 'dangerous' — sits at the centre of the whole piece, and it is the first place my habit of hunting for numbers pays off. Dangerous at which level? Dangerous for whom? Under which time control? To answer those three questions, we have to descend to the board.
The product: six videos, one plan
The structure is simple. Six instructional videos for the Black player, each covering one opening plan. The systems covered are the Colle System, the Trompowsky Attack, the Torre Attack, the London System, the Catalan, the Blackmar-Diemer Gambit and the Richter-Veresov Opening. The idea is this: when White avoids main-line theory and plays these 'system' openings, Black will have a ready answer.

In the language of the education market, this is a classic 'niche-solution' model — a narrow answer built for a high-intent problem. To a player who has just felt helpless against the London System three rounds in a row at a club tournament, this product looks made exactly for them. And that feeling — 'my pet opening is losing me games' — is the real engine of this market.

The taxonomy: a mixed bag
The first problem is taxonomic. These seven openings are presented as one family, but they are not one family. The Colle, London and Torre usually arise after 1.d4 d5, where White deliberately refuses to play 2.c4. The Trompowsky, Richter-Veresov and Catalan usually arise after 1.d4 Nf6. The Catalan is actually main-line theory — 1.d4 Nf6 2.c4 e6 3.g3, a main-line system with a fianchettoed bishop and a queenside bind. The Blackmar-Diemer Gambit (1.d4 d5 2.e4) is a sharp gambit, an entirely different species.
Selling these as one 'after 1.d4 d5' family is a simplification, and the simplification itself tells you the product was built for convenience and marketability rather than theoretical precision. The first test of a repertoire product is whether its taxonomy is honest; here the taxonomy is deliberately loose.
Yet there is a truth hidden behind the taxonomic looseness. The Colle, Torre and London share one deep intention: White wants to bypass the vast theoretical territory of the Slav, Semi-Slav, Queen's Gambit Accepted and Orthodox QGD. By not playing 2.c4, White never enters that battlefield. That is their real identity — they are a kind of non-cooperation movement against main-line theory.
Why these systems grow in empty space
A structural observation is needed here, as is my habit. I follow the transfer market the way a meteorologist follows pressure fronts — from which direction pressure is coming, which way the wind is turning — and the opening meta must be read the same way. Over the past decade, chess has seen a clear change in the wind: at club level, and sometimes even at elite level, the popularity of anti-theory, simple setups has risen. The London System is no longer merely club furniture; in recent years it has been used as a low-risk weapon even at the very top.
There is a simple explanation for this change of wind: time. A professional player's hours are limited, and information is infinite. When a player calculates that, against an opponent's main-line preparation, a system opening yields more practical return per unit of preparation than the main lines do — they choose the system. The rise of system openings is therefore not a story of new theory; it is a story of the economics of preparation time. And where demand rises, supply rises — the existence of an 'anti-system' product for Black is indirect proof of White demand.
This point matters, because although the product sells itself as a defence against White systems, its reason for existing is the success of those systems. The more the London System appears at elite level, the bigger the market for anti-London products. Attack and defence here are two sides of one coin.
Analysing the word 'dangerous': for whom, at which level
Back to that one word. The product description says these four systems are 'extremely dangerous', and the basis offered is 'the painful experience of many players'. I am not willing to read that sentence as analysis, because it is an appeal to experience, not evidence. There is no match sample, no engine-match rate, no ACPL, no win-draw-loss record.
My years of watching matches tell me the word 'dangerous' is level-dependent. At elite level, where Black has weeks of preparation, a well-prepared Black player is generally comfortable against these systems. There, the real danger is not in the system but in the White player using it — because White knows the limits of his own plan, and so does Black. But at club level, roughly between 1500 and 2200, the picture flips. There the opponent is not prepared, and by the time they understand what to do against the slow grind of a Colle or a London, it is too late.
So the word 'dangerous' is not wrong — it is sent to the wrong address. These systems are not risky in elite chess; they are risky at the improving amateur level — and the product is written for that second audience. Here I grow a little suspicious. Anyone packaging six IM videos as a principled defensive system knows his buyer is not elite. He knows the buyer is the 1700-rated player who lost to the London three times last month.
Black's defensive structure: a plan instead of theory
From Black's side, the real problem against these systems is not a lack of preparation but a lack of plan. In main-line theory Black has a map — which pawn, which square, which file to control — and almost everyone knows it. In system openings that map does not work, because White has deliberately chosen a debatable, a-theoretical path. Black must build a plan of his own, and that comes not from memory but from understanding.
I once thought this was only a matter of chess literature. Sitting at the Moscow set-piece desk in 2026, I learned the opposite lesson. There I logged all 64 matches and 169 goals and ran a daily eight-minute set-piece breakdown. In the final, France beat Croatia 4-2; France scored 14 goals across seven matches, Griezmann four, Mbappé four at nineteen. I had called Croatia's second-half drop-off before kick-off, citing three consecutive extra-time matches, two of them shootouts. A senior producer suggested the tactics block should go to a former male international. I kept the block, but answered not with an argument but with a tracking model — that INTP reflex that reads as coldness in the studio and as rigour in print.

Moscow taught me to read 'rehearsed chaos' in the language of planning. Black's defence against system openings is the same — not a rehearsed, pre-built reaction, but a structure standing on a small number of specific principles. Since 2026 I have banned the word 'momentum' from my scripts unless I can attach a number to it. The same is needed here: not 'the London is dangerous', but 'Black suffers in this specific plan because of this square occupation and this pawn structure'.
The structure of the quote: Turlov, Lilov and an unverified pairing
Now to that crack I began with. The headline carries a quote — 'Chess is massively undervalued' — attributed to 'Turlov'. But the body is a promotion of Lilov's video product. There is no connective tissue between the two. Turlov's quote and Lilov's product are not bound by the same logic.
This is not a small editing slip. It is a sourcing signal. When a piece's headline and body come from two different sources, you know the piece is not editorial analysis but a pasted marketing placement. In such paste-ups, a quote is often used to borrow prestige — a recognisable name, a big sentence, and a veneer of sophistication over the product.
To me, the identity of 'Turlov' is unconfirmed. If he is a known chess patron or executive, the quote was probably pulled from an interview or a sponsorship context, unconnected to the Lilov material. If he is not, the question is bigger — who placed this quote here, and why. Until the primary source is cross-checked, this quote is not evidence for the piece, only decoration.
This caution is instinctive for me. The anchor chair taught me that silence is a production cue — that what is not said is also part of the edit. When a quote is cut from context and planted, the silence around it becomes the real story. Here the silence is this: no one shows the connection between Turlov's words and Lilov's work.
Where Lilov stands: a coach persona, not a player profile
One thing must be made clear. Valeri Lilov is an International Master and a Bulgarian trainer. But in this piece his relevance is not his competitive record but his coaching identity. No current rating, recent tournament result or rating-versus-form gap is raised here, because there is no need — he is a content creator here, not a player.
That distinction matters, because it saves us from a common error. We often judge a trainer by a player's yardstick — his rating, his tournament results. But value in the coaching market is created differently: the ability to solve a niche problem, clarity of explanation, and the ability to hold an audience. Lilov's authority here rests on an appeal to experience, not on evidence. That is not necessarily a weakness — but the buyer should recognise it.
The most likely reading of this product for me is this: it is part of a larger course library, perhaps repackaged content, not new theoretical research. That is not a bad thing. Repackaging is a normal model in the education market. But the buyer should know whether they are buying new theory or a tidy practical guide.
The transmission map of the education market
Now let me step back. Where does this kind of product sit in chess's industry structure?
Upstream is youth training and talent supply. In the middle are events, players and platforms. Downstream are content, commerce and derivative markets — courses, books, subscriptions. Lilov's six-video product sits at the very bottom layer, in the derivative market.
This layer has its own logic. It is a low-risk, high-margin model. Identify a narrow problem — 'my opponent always plays the London, what do I do' — and sell a ready-made solution. Its impact on youth training is near zero, and not on event structure either. But it has a small yet real indirect positive effect on online platforms, streaming content and sponsorship commerce — because every education product increases time spent on platforms, and time spent is the currency of this market.
There is a subtle point here. This product's impact will never be systemic — it is a course-sale story, not a championship story. But its existence testifies to a larger truth: the economic centre of the chess boom is shifting from play toward education. Once, chess income meant tournament prizes and sponsorship; now chess's most stable income is selling the demand for improvement.
A South Asian mirror: Dhaka, Delhi
This is where my own map comes in. I was born in Bangladesh, live in Delhi, and cover chess for the India market. Holding these two countries in one frame produces a structural mirror directly relevant to this education-market story.
India's chess system stands on a built pipeline and a large domestic market. Bangladesh's story is the reverse. In 2026 Niaz Murshed became South Asia's first grandmaster — a year before Anand. But Bangladesh treated it as a moment, not a movement. Today India has more than eighty grandmasters; Bangladesh has five ever. The BCF's annual government support is roughly eleven lakh taka. In 2026 the Standard Chartered school chess pipeline shut down. No new Bangladeshi grandmaster has appeared since 2026 — not a talent drought but a sponsorship and jobs drought. In July 2026 Ziaur Rahman died at the board, an indictment of the system.
Against this background, a product like Lilov's six videos becomes a strange mirror. To a player with no domestic coach, no domestic league, no durable training structure, an online education product is the only affordable path. But the danger lies here. If a product teaches an improving player to 'memorise these six systems', they do not learn to understand openings; they learn to memorise patterns. And where the training infrastructure is weak, this memory-driven learning can easily become the only learning. System-opening education is a luxury only when a coach stands beside it to teach the understanding; without a coach, it becomes the door that shuts on comprehension.
I say this not from patriotism but from structure. India is not a podium of superiority here, but a structural mirror — showing how education products work when pipeline and market exist together, and how they become isolated when one is missing.
Contrarian: the real risk is not on the board but in the market
Now the counter-angle I enjoy hunting for in every product analysis. Conventional wisdom says the risk of this product is technical — maybe the videos are not good, maybe the plans do not work. I would say the real risk lies elsewhere.
The first risk is informational, and it is the buyer's, not the game's. When a headline and a body come from different sources, the reader must think twice before believing any claim. If 'extremely dangerous' is written without evidence, the buyer should read it as marketing, not analysis.
The second risk is pedagogical, and it is my most important observation. Selling a system opening as a single, self-contained answer does a particular kind of harm. If a player thinks 'I have six answers to these six systems, done', they do not build opening understanding — they build a reaction library. At club level this works temporarily, but it breaks down at higher levels, because there the opponent knows the reaction.
The third risk is this article's own. When a piece joins a pasted marketing pitch and an unverified quote, it is a large signal — some of the content around this product is not maintaining editorial standards. A product's biggest risk is often not its own quality but the quality of the marketing literature around it. If the buyer buys on the strength of that literature, the loss is bigger than the course fee — it is time, and habits built in the wrong place.
One caution is needed here: I am not saying this product is bad or that system openings should not be studied. I am saying the language of marketing and the value of education are different things, and merging them takes away the buyer's own tools for deciding.
Sustainability: evergreen, or a permanent segment
Now the question of sustainability. Is this kind of product a passing wave, or a permanent market segment?
My reading is this: it is evergreen content, not time-sensitive news. It has no expiry date. As long as the London System exists at club and elite level, the demand for anti-London products will exist. So the key signal of this market is not any single course but the steady flow of niche-repertoire products.
Three signals I am watching. First: the identity of 'Turlov' and the original source of the quote — if he is a known chess patron, the quote is not merely marketing but a signal of chess financing. Second: the flow of anti-system repertoire products — if such niche products keep growing on course platforms, a permanent segment has formed in the education market. Third: elite use of the London complex — if it continues, the 'low-theory trend' narrative is confirmed, and the market for Black's defences grows further.
Of the three, the first is the least verified and perhaps the most significant. Because if the quote is tied to a real patron structure, the story changes — then it is no longer a course-product story but a story of patron capital entering chess. I do not yet know whether that is so. And where I do not know, pretending certainty is not my method.
Takeaway
So what stands? On the board, a product; in the market, a demand; above it, an unverified quote.
What I can say with certainty is this: chess's economic centre of gravity is shifting from play toward education, and in that education market the fastest-growing thing is exactly the kind of niche product that stands on the anxiety of the improving amateur. Lilov's six videos are a normal sample of that market — neither good nor abnormal. But the marketing literature around them raises a different caution: an unverified quote, a loose taxonomy, and an evidence-free word, 'dangerous'.
I am not sceptical of anti-system products. I am sceptical of the moment when a product teaches the buyer what to think but not how to verify for themselves. Chess has never been, to me, a game of memorising the right answers — it is a structural test in which every opening declares its strength by admitting its weakness. The London System survives because it admits its weakness; the Colle and Torre do the same work slowly. The real weapon against them is not a six-video package but a clear plan and the patience to carry it.
So I turn the question to the buyer, directly. When your opponent plays the London twice in a row at your next club tournament, will you have a memorised reaction, or an understanding? Because the difference between those two shows up exactly where no course page reaches — under the clock, on the board, in an unfamiliar position. And that moment is still chess's most honest teacher.
