1. An Evening That Told Me the Business Plan
A small club room across the Neva, February, ice on the window glass. White plays d4, then Nf3, then Bf4. Inside thirty seconds the entire army is in formation — d4, e3, Bd3, Nbd2, c3, and eventually e4. The Black player across the board is rated around 2026; his eyes go to the clock twice, then he simply plays...d5,...Nf6,...e6,...Bd6. Nothing collides for twenty-five moves. White slowly takes the c-file, Black's knights become homeless one by one, and on move thirty-five Black resigns.
Here is the detail that matters: White never played 2.c4. Not once. The whole theoretical cathedral of the Queen's Gambit — Slav, Semi-Slav, Queen's Gambit Accepted, Orthodox Defence — never touched the board. What White played was not an attack; it was a position. Not a winning machine, but a suffering-prevention machine. In thirty-three years of standing beside boards from Dhaka to St Petersburg, this is the scene I keep watching. The main lines of the Queen's Gambit have quietly become a tax at club level — those who don't study it pay that tax, move by move, every evening.
This piece is about that fatigue. But it is not a technical report. What landed on my desk is a promotional document for an instructional product: Bulgarian International Master Valeri Lilov offers six video lessons claiming to give Black a plan against the Colle, the Trompowsky, the Torre and the London System — plus the Catalan, the Blackmar-Diemer Gambit and the Richter-Veresov Opening. My job is not to praise or destroy. My job is to turn the board around and count what is shown, and what is left out.
2. How the Tax Was Built
The Queen's Gambit is not a game; it is a question. White plays 1.d4 and then 2.c4, asking whether Black will accept the tension on d5 or step aside. The classical answer has accumulated for a century: Slav and Semi-Slav build-ups, the active tension of the Queen's Gambit Accepted, the precise pawn structures of the Orthodox Defence. Each of those carries years of memory, analysis and engine verification. That knowledge is expensive to store, and at club level players with two spare hours a week will not pay for it.
So a clear tendency has emerged: skip 2.c4 entirely. Play d4, then Nf3, e3, Bd3, c3, Nbd2 — and the whole theoretical catalogue stays outside the room. The Colle System, the Trompowsky, the Torre Attack, the London System: four setups that do exactly this. White seeks order, not a theory storm. And what sits on Black's side of the board? A simple answer should exist: correct preparation. In practice, what exists is irritation and no time.
That gap is the business. The number of White players avoiding the main Queen's Gambit lines is large at club level — in my own observation, close to a majority. Against a setup that carries no compulsory theory of its own, an unprepared Black simply gets squeezed. Lilov's six videos are entering that market, and the market is real.
3. The First Crack Is in the Title
The document I received is inconsistent on its first important line. The headline reads: 'Chess is something magic' — an interview with Timur Turlov. The body, however, promotes a Lilov video series. No interview, no tournament report, and two different people. An interview headline has been placed on top of a product advertisement.
I am not inflating this. But chess journalism survives largely on federation press notes and platform marketing documents, and this kind of mismatch should not be waved through. If the title points to Turlov, the reader expects a patron or a decision-maker speaking. Opening the piece, the reader finds opening plans. Worse is the second crack: every 'fact' in the document traces back to the writer's own sentence or an empty source field. 'Many chess players consider these systems extremely dangerous' is an opinion, not a data point. Dangerous to whom, how many, at what level, measured against which database? There is no engine match rate, no average centipawn loss, no game count. The product is being built on exactly what is missing.
4. The Mistake of Putting Two Families Under One Umbrella
Seven openings appear in the Lilov list, and that list rests on an error — treating all of them as 'ways to avoid the Queen's Gambit.' In reality there are at least two families.
The first family is structural: London, Colle, Torre, Trompowsky. Their aim is to dodge main theory, but a century of positional knowledge sits behind them too. White is not looking for complications; White wants a structured middlegame with undiminished winning chances. These systems are not dangerous. They are annoying. Annoyance and danger demand completely different answers from Black — annoyance is answered by accurate equalisation, danger by constant concrete verification.
The second family is theoretical: the Catalan, the Blackmar-Diemer Gambit, the Richter-Veresov. The Catalan is not a sideline; it is a mainline with seven decades of accumulated theory behind every move. The Blackmar-Diemer is a semi-sound gambit that demands not a plan but a precise move list. The Richter-Veresov is so rare that preparing against it is itself a cost-benefit question.
One 'plan for Black' template cannot serve both families. The point is simple: the player crushed by a Catalan needs structural instruction, while the player caught in a Blackmar-Diemer trap needs memorisation. Putting both side by side in one video set produces not education but a catalogue.
5. Six Videos, Seven Doors, One Arithmetic Problem
Now the most practical question, the one that sits outside praise and criticism: six videos. Seven openings. Including the Catalan. At a generous thirty minutes each, that is three hours in total. A serious Black player would spend three hours on one branch of the Catalan alone. Six hours, spread across seven openings, leaves roughly twenty-five minutes per door.
Twenty-five minutes can genuinely teach the London plan — if it teaches a plan rather than lines. Against the London, Black's task is essentially one thing: erect the...e6/...d5 wall, improve quietly with...Bd6,...Nbd7,...Re8, and then break the structure with...c5 or...e5. There is no compulsory move chain because White brings none. Black's victory is not on the board but in time: whoever breaks the structure first writes the story.
In the Catalan, twenty-five minutes is self-deception. Every Black decision there matters separately — hold the tension, accept the gambit, push, or keep the flank closed. Those are line-dependent decisions, and lines mean memory. Six hours for seven openings, one of which is the Catalan, is not a coverage claim; it is a marketing claim.
Some readers will object that club players don't need depth. True — and that is precisely why the Catalan should not be on the list. If depth is not delivered, the name serves only as ballast for the sales page. That is advertising's duty, not a teacher's. Confusing the two leaves a product with nothing but a title.
6. In Black's Language
Against the London: Black builds the wall first and reacts second —...d5,...Nf6,...e6,...c5 in some order, so that White's eventual e4 push hits an intact structure. Against the Colle:...c5,...b6,...Bb7,...e6,...Nbd7; never accept Colle's pace. Against the Torre:...e6 and...d5 first, then...c5 or...Qb6 to hit d4 and b2. Against the Trompowsky: accurate...e6,...c5,...Nc6, allocating space before White's bishop relocates.
This is traditional plan-based teaching, and it is what actually works for players with two hours a week. But writing honest plans forces honesty of scope: three openings covered properly beats seven covered thinly. Lilov's list walked the other way.
7. 'Extremely Dangerous' — Who Says So, and Why
The document tells us that many players consider these systems extremely dangerous. We are not told who, how many, or at what level. My experience says the opposite: these systems are low-variance, low-drama, low-risk. The London protects White; it does not attack. The honest description is 'painful without preparation,' not 'dangerous.'
A market psychology is at work. Defensive products sell best when the threat is inflated. Volume is replaced by fear, depth by sensation, system by magic — and the magic is already in the headline, where it never reaches the board.

8. The Real Gap Is Not a Repertoire
Let me step outside the product for a moment. At club level, Black's real crisis is not the opening. A 2026 player's problem is not the first ten moves; it is losing the thread between move twenty and move forty. Watching a twenty-five-minute video is easy; remembering it at a kitchen table in Dhaka is hard. In the video, the engine is running. On the board, it is not.
No video replaces a coach sitting beside the board saying: in this structure, Black has one plan. Six videos cannot do that.
9. The Dhaka Mirror
I see the same process in my own country. Virtual courses multiply; hands-on coach education does not. The Bangladesh Chess Federation's annual budget has hovered around 1.1 million taka — less than a single franchise cricketer's bat deal. In 2026 a teenager in Dhaka became South Asia's first grandmaster. India turned that moment into a national pipeline; we built a statue. Twenty-seven years later, the count is still short.
The market logic in Moscow and the market logic in Dhaka are the same size: buyers want a solution, sellers supply a list. Solutions — a board, a coach, one dedicated hour a week — cannot be sold in six parts.
10. Takeaway: The Question I Want to Ask the Videos
I do not doubt Lilov's intent. An International Master who teaches has every right to sell plans, and this market called him because demand is real. My question is different: does the video teach structure, or does it teach moves?
If structure, it is an aid, and the only argument left is delivery. If moves, it is a time bomb — because when memory fails, the player blames the video, not himself.
So: play the first ten minutes. If you see pawn structures on the board and hear 'in this structure, Black is fine here,' that is a resource. If you see only move orders and warnings, ask where your money is going.
In August 2026 I called an online Olympiad final from my own kitchen, where two teams sat with equal claims to gold because nobody had touched a board in the same room. The lesson that night was plain: we forget the difference between the screen and the board, and that difference is where most of the loss lives. The board remembers what the camera missed — and that truth still does not sell in six parts.
