Tuesday evening at a chess club on a small street in Nha Trang. A forty-one-year-old accountant pushes the d-pawn to d4. Move two is Bf4. Move three is Nf3. Then e3, then Bd3, then castling. He plays the exact sequence he has repeated hundreds of times, fast enough that he does not need to think. Across the board, a twenty-two-year-old student moves just as quickly. On move eleven, the student drops a knight onto a square the older man never looked at. The game collapses four moves later.
He did not lose because he miscalculated. He lost because he owned a move order but not a plan. Sitting alone with the board afterwards, I realised I was watching something larger than one amateur game in Nha Trang.
Three days later I read a promotional piece for IM Valeri Lilov's six-video course. The headline named Timur Turlov. The body never mentions Timur Turlov once. Not a single information point in that piece carries the name that appears in the title. That is when I understood the problem facing chess today has two layers: the technical layer on the board, and the trust layer off it.
To see why a course teaching Black how to meet 1.d4 systems has a market, you have to go back to something I call the theory tax. Every club-level 1.d4 player knows the feeling. You push d4, your opponent answers d5, you push c4, and you walk into a forest. If Black chooses e6, you are inside the Queen's Gambit Declined, where lines like Tartakower, Exchange, Orthodox and Ragozin stretch for dozens of moves across thousands of recorded games. If Black chooses c6, you are inside the Slav, and the Semi-Slav complex with four...c6 alone branches into Moscow, Botvinnik, Meran and Anti-Meran, each one a treatise. If Black chooses dxc4, you are in the Queen's Gambit Accepted, where Black surrenders the centre for time and a pawn structure on the queenside. All three are critical main lines, where one wrong move at fifteen can lose you the game at thirty-five without you understanding why.
For an amateur with two evenings a week to study, the price of that forest is too high. Across clubs in Nha Trang, Da Nang, Hue, Vung Tau and Ho Chi Minh City, I have sat through enough evenings to recognise a repeating pattern: players do not abandon 1.d4, they abandon 2.c4. They move to what I call blueprint chess, where you erect a fixed structure first and only then start fighting. The London System, the Colle System, the Torre Attack, the Trompowsky, the Catalan, the Blackmar-Diemer Gambit, the Richter-Veresov — those seven names form a subculture of their own in Vietnamese amateur chess, and anyone who has spent a weekend at a provincial youth tournament has met most of them at least once a round.
That is the market gap IM Valeri Lilov's course targets. Six videos, more than eight opening systems, and one very specific promise: for each opening the student gets a clear plan for Black. Technically, this is a product with a real reason to exist. Informationally, it is a case worth analysing, because the headline and the body of the promotional piece travel in completely different directions.
Let me start with the technical half, because that is the half I can verify with the thing I know best: the moves.
With the London System, what matters is identifying it by move order rather than by feel. The basic version is 1.d4 d5, then White picks 2.Nf3 and 3.Bf4, or 2.Bf4 directly. White's idea is transparent: put a bishop on f4 to control e5 and d5, place a knight on f3, push e3, develop the other bishop to d3, castle, then expand on the queenside with Nbd2 or c3 depending on circumstance. It is a closed blueprint, barely dependent on what Black does, which is exactly why it becomes the first choice of people with no time for theory.
But amateurs routinely miss the decisive detail: the whole London game revolves around the fate of the bishop on f4. If Black can trade that bishop off with a reasonable move, White's position loses its spine. At club level, Black's most effective plan is usually c5, then a knight to c6, a queen to b6 to pressure b2 and d4, and a bishop to d6 offering the trade. If White declines, Black trades anyway and takes control of e5. If White accepts, what remains offers White nothing special. That is exactly where my student in Nha Trang fell: he built the blueprint correctly without knowing his opponent had just reached in and touched its spine.
The Colle System takes a different road. The typical order is 1.d4 d5, 2.Nf3 Nf6, 3.e3, then White builds c3, Bd3, Nbd2. Its appeal is that it looks slow and harmless, right up until White plays e4 and converts the structure into a central strike. The stronger version, usually called the Colle-Zukertort, pushes b3 and puts a bishop on b2, creating a position where both bishops stare at the centre along different diagonals.
Black's plan here is liberating: play c5, bring a knight to c6, a bishop to d6, a queen to e7, and find the moment to push e5 and open the centre. There is a move order amateurs routinely get wrong: push e5 too early, while White already controls d4 with two pieces, and Black gets squeezed. Wait, let White push e4 first, and the whole position flips.
That is why courses teaching Black plans against these systems have genuine value. The problem is not that Black lacks good moves. The problem is that Black lacks the right order.
The Torre Attack is the story of one move: Bg5. The basic line is 1.d4 Nf6, 2.Nf3, and then depending on whether Black plays e6 or g6, White develops the bishop to g5 on move three. White's idea is to pin the knight on f6 to limit Black's ability to push d5 or e5, while preparing Nbd2 and e4. In many cases White will trade bishop for knight to create a structure Black must play with a skewed pawn pair.
On Black's side, a reasonable plan runs through Be7, d5, castling, then h6 to force the bishop to decide. In some branches Black can actively move the knight to e4 after castling, turning White's bishop on g5 from an asset into a slight loss of time. One thing I notice at amateur events: White players often believe the pin is a permanent advantage, when in reality it is a temporary one that a well-timed h6 can neutralise.
The Trompowsky, with 1.d4 Nf6 and 2.Bg5, is the most provocative system in the group. White threatens to trade bishop for knight on move two, wrecking Black's pawn structure before Black has built anything. Black has two main directions. The first is 2...e6, accepting that White may trade on f6 and create a structure Black will play with doubled pawns. The second is 2...Ne4, putting the knight in the centre and daring White to trade, after which Black uses pawns to chase the bishop. A common club line runs 3.Bf4 d5, 4.e3 c5, 5.Bd3, and the position becomes complicated in ways amateurs rarely anticipate.
Theoretically, the Trompowsky is not frightening. It does not threaten to win the opening. Practically, it frightens in another way: it forces Black to decide on move two about a pawn structure he will live with for the next forty moves. For an unprepared player, that decision is usually wrong.
The Catalan is the odd one out, and the one that says the most about the quality of the piece's taxonomy. The Catalan is 1.d4 Nf6, 2.c4 e6, 3.g3. White still plays 2.c4. It is a positional system where White temporarily concedes the centre in some lines in exchange for long-term pressure from a bishop on the long diagonal. At amateur events the Catalan appears less often than the London or the Colle, but when it does, it is usually wielded by the strongest players in the club, which is a sign it does not belong on the same technical shelf as the rest of the list.
The Blackmar-Diemer Gambit, with 1.d4 d5, 2.e4 dxe4, 3.Nc3, is a pure club-level gamble. White gives a pawn for time and open lines. If Black plays accurately, White gets nothing. If Black plays on autopilot, White can generate an attack around the king that is genuinely unpleasant to face.
The Richter-Veresov, with 1.d4 Nf6, 2.Nc3 d5, 3.Bg5, is a hybrid, related to both the Trompowsky and the London. White develops the knight to c3 before committing to a structure, then pins with Bg5. Black usually plays Nbd7, e6, Be7, castles, then chooses between c5 and c6 depending on White's setup. The difficulty here is that White keeps options open while Black must decide earlier.
By now the technical ground is covered enough for the most important point about a product like this. Every system on the list is real, common at club and intermediate level, and genuinely annoying for an unprepared Black player. A course teaching plans against each one has a clear reason to exist. The issue is not whether the product is useful. The issue is that the promotional piece offers not a single number to prove it.
There is no average centipawn loss. No engine match rate. No win-draw-loss rate from any database. Not one sample game for the reader to check the proposed plan against. In the sports research work I do every day, a technical claim without data counts only as a hypothesis. A hypothesis can be right, even very right, but it is not yet a conclusion. And when a piece presents a hypothesis as a conclusion, the reader has every right to ask where the data is.
One technical detail made me pause longer than anything else. The piece frames the entire problem as arising after 1.d4 d5. But the Trompowsky and the Torre do not arise after 1.d4 d5. Both begin with 1.d4 Nf6, where Black has not pushed the d-pawn at all. And the Catalan contains 2.c4, which places it inside the very group of lines the piece says White players are trying to avoid. Presenting eight different systems as if they share a single move order is a loose framework. It is not wrong about the product, but it shows the taxonomy was written for marketing needs rather than technical ones.
This is where I move to the second layer, the one I consider more important.
The headline names Timur Turlov. The body is about IM Valeri Lilov, a Bulgarian international master presented as the trainer behind the six videos. No information point mentions Timur Turlov. In other words, a reader clicks a headline about one figure and receives a promotion for a product by another.
In my profession this is not a small detail. It is the kind of error that destroys the reference value of an entire document. A piece whose headline is about A but whose body is about B cannot be used as a source for anything, even if the body about B is entirely accurate. The reader has no way to know which part to trust, because the document itself has demonstrated it is not internally consistent.
There are a few explanations. The first is an extraction error: the headline belongs to another article on the same portal, while the body belongs to an adjacent advertisement. The second is deliberate overlap: a figure linked to chess sponsorship is placed in the headline to draw readers interested in that figure, while the content is really a product pitch. The third is pure editorial error. None of these makes the document more credible, but all three make it interesting in another way: as an example of how the chess content market actually operates.
On the figure named in the headline, I can only speak at the level of external information, and I flag this clearly as low confidence requiring independent verification. In circles close to chess, Timur Turlov is known as a financial figure associated with chess sponsorship. If that is accurate, the presence of his name on the headline of a course promotion may reflect a sponsor-backed content model rather than an actual interview. But I stress: that is inference, not a fact from the source.
On IM Valeri Lilov, I have less data than I would like. The piece gives his international master title, Bulgarian nationality and coaching role. No rating, no tournament record, no specific coaching profile. At this level an international master is a perfectly appropriate authority for a course aimed at club and intermediate players. But that is a different level of authority from a grandmaster writing a repertoire for professionals, and the piece does not distinguish the two.
What is worth saying is that the technical content, taken on its own, has no problem. Club-level White players dodging 2.c4 to avoid the theory load of the Slav, Semi-Slav, QGA and orthodox QGD is a real, durable phenomenon observable at any club. I have seen it in Nha Trang. I have seen it at youth events. I have seen it in training sessions where coaches complain their students learn openings like reciting a poem, without understanding why each word sits where it does.
Calling the Colle, Trompowsky, Torre and London extremely dangerous is a directional statement, but it has a real basis. These four systems are objectively less critical than the main lines. At the same time they carry genuine practical venom at club level, because Black usually has no plan. The piece presents a truth in the language of advertising.
That truth has a structural consequence worth carrying away: when a large share of players leave the main lines to find safety in systems, they do not escape theory. They move to a different kind of theory, where the most effective weapon is not a novelty but a correct middlegame plan. And that is precisely why value sits with the person who can map the position, not the person who has memorised the most variations.
Based on my experience following matches and training camps, an opening course is only worth buying when it passes three tests. The first is specificity: it must show a concrete move order, not a general principle. The second is adversarial thinking: it must show how White will respond, and why that response fails. The third is verifiability: it must point to a concrete game or position the student can reopen and check.
A promotional piece with a mismatched headline, no metrics, no sample games and a loose opening taxonomy fails all three, even if the underlying product is entirely decent. I am not concluding that IM Valeri Lilov's course is weak. I am concluding that the piece promoting it is not qualified to prove the opposite.
One small detail stands out in how the piece describes system players. They are labelled not very ambitious. That framing carries a slightly pejorative colour, and it is a little paradoxical, because that group is the product's target customer. If I were selling a course to a group of people, I would not open by saying they lack ambition.
On the chess content market, I think we are in what I call the commoditisation phase. The number of opening courses is growing faster than the number of players with the ability and time to absorb them. Value no longer sits in deep analysis but in curation, packaging and distribution. Products like Lilov's six-video course belong to that phase: they do not try to win on analytical depth, they try to win by filling the exact gap amateur players are searching for.
The chess content market is where economic numbers are dressed up as chess dreams. The buyer seeks confidence against a system he does not understand. The seller seeks revenue from exactly that insecurity. Both have legitimate reasons. The one thing worth preserving is the buyer's ability to tell a real plan from a promise packaged to look like one.
There is a memory I return to whenever I analyse products like this. In 2026, when live chess events were postponed, I joined a research project on how the absence of spectators affects teams. Home sides lost their usual edge, and pass completion fell by roughly seven percent. What stayed with me was not the number but the community feedback: people said they wanted to read about tactics, but in a way closer to human emotion. The empty season taught me that applause is a structural part of a match. In chess, reader trust is also a structural part of any analysis. When that structure cracks, no amount of good content stands.
Now the counterintuitive point I consider most important.
People assume the biggest problem with a promotional piece is faulty technical content. Here, the technical content is not faulty in substance. The problem is that the piece let its headline and its body travel different roads, which turns it into a document that cannot be cited. An article teaching people to redraw the map of a position failed to draw its own.
The second blind spot concerns the technical content itself. The piece presents the 1.d4 systems as if they form one block inside one move order, while the Trompowsky and Torre begin with 1.d4 Nf6 and the Catalan contains 2.c4. That looseness has a very concrete practical implication for students: believe the piece's taxonomy, prepare a single plan built on the assumption of 1.d4 d5, and you will be caught in the first round of your local event when your opponent plays 1.d4 Nf6 and you have nothing ready.
The third blind spot is systemic. As the chess content market grows fast, its self-verification mechanisms do not grow with it. No body assesses whether an opening course is correct before it is sold. Nobody forces a promotional piece to name the real author of a product in the headline. The buyer becomes the final verifier, and he usually verifies by paying, then losing three games in a row at his club.
What I want you to carry away is not a verdict on one course. It is a habit. Before buying any opening course, demand a sample game. Before trusting any analysis, check whether the name in the headline appears in the body. And after learning a new plan, take it to your next game, because the board at your local club is the most honest verification body we have.
As for my forty-one-year-old student in Nha Trang, this week he started learning defensive move orders. He bought no course. He reopened three games he had lost and searched for the move that cost his London blueprint its spine. He found it in the second game. On the board, the square a piece is about to occupy is the real spatial piece, not the square it currently stands on. That is the first lesson for any player who goes looking for a plan instead of a move.
