The Theory Tax and the Detour of Club Chess Players

On a Thursday evening, in a small chess room on Nguyen Thi Minh Khai Street, the man at board four pushed his d-pawn to d4. His opponent, a second-year student, answered with d5. He brought his knight to f3, then his bishop to f4. No c4. Across the next thirty-two moves, the queenside was never opened along the classical path. I sat at the neighbouring board, recording each move in a notebook with a worn spine, and realised this was the twelfth game in three weeks in which I had watched the same pattern: London, Colle, Torre, Trompowsky — and never 2.c4.

The student lost after thirty-two moves. The man stood up, smiled, and said something I had heard at least five times that month: "I don't want to memorise an entire library."

What is happening at club boards carries a different name: emigration. And at the far end of that emigration, a market is quietly growing.

A tax nobody invoices

Club-level players pay a fee nobody names. I call it the theory tax.

Opening with 1.d4 d5 2.c4, White steps into a labyrinth drawn out over more than a century of analysis. The Slav with 2...c6. The Semi-Slav with the 4...c6 complex. The Queen's Gambit Accepted with 2...dxc4. The Orthodox Queen's Gambit Declined with 2...e6. Each branch is a library. Each library has sub-branches, novelties, model games stretching from the 1930s to last week. A serious player wanting full command of these four systems needs thousands of hours and a memory that is not allowed to waver.

For a club player with a job, a family, and one Thursday evening a week for the board, that tax exceeds what he can pay. He chooses another road. He builds a fixed setup where move order matters less than plan, where he does not need to recall move eighteen of a game played at Wijk aan Zee in 2026.

That is why the London System, the Colle System, the Torre Attack and the Trompowsky Attack became popular detours. They do not demand memorisation; they demand only that the player understand what he is building.

I have followed Vietnamese chess for more than eleven years, and this phenomenon is everywhere, from Hanoi chess corners to clubs in Can Tho. Amateur tournaments, weekly club nights, cafe games — in those places, 1.d4 rarely comes with 2.c4. People know the move exists. They have done the arithmetic and chosen not to play it.

What is being sold

In that gap, a market forms. If thousands of players keep choosing systems to dodge theory, those thousands are inadvertently creating a new demand: to be prepared against the very systems they themselves avoid.

A Bulgarian coach, International Master Valeri Lilov, steps into that gap with a package of six videos. The course description lists London, Colle, Torre, Trompowsky, Catalan, Blackmar-Diemer and Richter-Veresov. It adds that these systems are extremely dangerous, and that for each one the learner receives a concrete plan for Black.

I read the description several times. One detail made me pause longer than the rest: six videos, but seven system branches listed, not counting the four main theoretical lines mentioned as things to avoid. Anyone who has produced teaching content knows what that division yields. Each topic receives a single plan — compact, memorable, and surface-level.

The opening lines note that many White players skip 2.c4 to avoid Slav, Semi-Slav, Queen's Gambit Accepted and Orthodox QGD theory. That observation is correct. I have verified the same pattern myself over years: in amateur events, the share of games turning into systems rather than main lines runs consistently higher than in events rated 2,000 Elo and above.

The accuracy of an observation does not automatically turn it into an honest sales argument. Here, the document supplies no figure to back the observation — no percentage, no data sample, no survey window. Everything stops at the level of assertion.

What those plans actually look like

I spent three evenings reconstructing the named systems along the move orders any opening manual records.

The London runs 1.d4, then Nf3, Bf4, e3, Bd3. Black's plan usually revolves around timing ...c5 correctly, trading off the f4 bishop with ...Bg5 or ...Nh5, and exploiting how White's d3 bishop turns passive once the pawn structure is blocked.

The Colle runs 1.d4 d5 2.Nf3 Nf6 3.e3. It is a purely plan-based system: White will push e4 once prepared, and Black must break that rhythm before it forms.

The Torre runs 1.d4 Nf6 2.Nf3 e6 or g6, then 3.Bg5. The Trompowsky runs 1.d4 Nf6 2.Bg5. The Catalan runs 1.d4 Nf6 2.c4 e6 3.g3. The Blackmar-Diemer Gambit runs 1.d4 d5 2.e4 dxe4 3.Nc3. The Richter-Veresov runs 1.d4 Nf6 2.Nc3 d5 3.Bg5.

Read closely, a problem surfaces. The Trompowsky and the Torre never arise after 1.d4 d5. They arise after 1.d4 Nf6, when Black chooses an Indian defence rather than a symmetrical one. The Catalan contains 2.c4 — precisely the move the course claims White is trying to avoid.

The promotional logic is loose at the very first layer. Systems are gathered into one basket even though they do not share a Black move. For a teaching product, that looseness means something. It shows the syllabus was organised on marketing criteria — whatever club players encounter often — rather than theoretical ones, where systems sharing a family of variations would be grouped together.

For the learner, this ambiguity does no direct harm. A Black plan against the Trompowsky can still be useful even if it does not belong to the same family as the plan against the London. But it raises a question about how the material was compiled: if the classification at the most basic level is loose, how much verification does the deeper technical content deserve?

When the name in the headline never appears in the body

Here the story turns in a direction I had not anticipated.

The document I accessed was titled as an interview with Timur Turlov. Yet reading the entire content, the name Timur Turlov does not appear once. Not in the course introduction, not in the list of opening systems, not in the description of the coach. Conversely, the name running throughout the content — Valeri Lilov — never appears in the headline.

Headline and body appear to belong to two different documents.

For someone whose work is recording, this is the most serious kind of discrepancy. It does not affect the quality of any move, but it breaks the only thing that makes a piece of writing trustworthy: the match between what is promised and what is delivered.

I do not have enough evidence to say what happened. Perhaps the original was a genuine Timur Turlov interview, and the course content was merely an advertising block placed on the same page. Perhaps the data-capture system pulled a headline from a different article on the same portal. Perhaps this is sponsored content, where a sponsor's name sits in the headline position as brand endorsement while the actual product lives in the body.

All three possibilities lead to the same conclusion: the document's reliability at source is in question, and every technical claim inside it needs independent verification before use.

Another detail caught my attention. The document supplies no Elo rating for the coach, no sample games, no win-draw-loss statistics, no engine data. Every judgement comes from one side: the seller. In the chess-content industry this is common. But it means words like extremely dangerous should be read as a sales pitch, not as a research finding.

The coach's standing also needs placing correctly. An International Master is a genuine expert, above most amateur players. But on the ladder of opening instruction, above him sits an entire tier of content written by Grandmasters, with deeper systems, denser data, and usually far larger distribution platforms behind it.

The market behind the board

The emigration of club players away from 2.c4 has created three layers of demand.

The first is the demand to learn. Players want a setup that is easy to remember, easy to operate, and light on memory.

The second is the demand to counter. Black players, after losing repeatedly to the London or the Trompowsky, start looking for answers.

The third is the demand for guidance. Amid an ocean of free video content, learners need someone to tell them where to start.

The six-video course targets the second and third layers. Its competitive advantage lies in compression: one plan per system, enough for a learner to sit down at a Thursday game without drowning. Its weakness lies in the same place: compression means surface, and surface does not hold up against a better-prepared opponent.

My experience following games at amateur events shows a repeating rule. System players win a lot early, while opponents are unfamiliar with the setup. Once opponents have seen it enough, the gap closes quickly. A system's advantage lies in surprise, and every surprise has an expiry date.

This circle feeds itself. Players avoid theory to save time, then buy content to deal with people avoiding theory just like them. The original tax does not disappear. It only changes collector.

The empty stand of a teaching economy

One thing is rarely mentioned when discussing the chess content market: most learners never appear in any statistic.

They have no regularly updated Elo. They do not play in streamed events. Their names appear on no ranking list. They exist only in small chess rooms on Thursday evenings, paying a modest fee, playing a few games, then going home.

An empty stand still carries an echo — you only need enough stillness to hear it. Listening closely to the chess content market, you hear this group most clearly of all. They are the reason every opening course, every video package, every promise of a memorable plan exists. And they are also the least equipped to judge what they have just bought.

A player rated 2,300 can read an opening document and immediately see what is solid and what is not. A player with two hours a week has no such tool. He has only trust.

What remains after the board is folded

I thought about all this as I left the chess room that night, after the man at board four packed his pieces into the wooden box and carefully closed the lid.

He does not know the name Timur Turlov. He does not care whether the course has six videos or sixteen. What he knows is that he has two hours a week, and he wants to spend them playing chess, not memorising.

We search for the sound of the stand from back then and find our own youth inside the noise. For today's generation of club players, that noise takes another shape: thousands of opening variations uploaded daily, hundreds of courses on sale, and a widening silence where a trustworthy guide ought to be, someone to show them the shortest road.

Generations will pass, but the poem written about them keeps being written. What I want to keep from this story sits somewhere other than where the headline points.

A course can teach someone how to handle the London or the Trompowsky. It cannot teach the more important thing: how to tell a good salesman from a good teacher. In a market where six videos cover seven systems, where a name in the headline does not exist inside the body, that skill becomes a matter of survival — for the wallet and for trust.

Club players are doing exactly what players of every era have done: choosing the road that lets them play more. The real price of a game of chess is not in the final move. It is in how many evenings were traded to sit at the board, and in whom we trusted to lead us there.
