The Club-Level Theory Tax: Six Videos for Black and a Name That Is Not in the Article

Moscow, a Thursday evening in late January, the basement of an old school in the Tagansky district. Board four. White is a man of about forty, grey sweater, pushing the d-pawn on move one, the bishop to f4 on move three, the knight to f3, then the pawn to e3. Not once does he touch c4. Black is younger, looks book-trained, opens a densely written notebook and thinks for twenty minutes on move six. He loses on move thirty-seven. The striking part is that he loses without making any clearly bad move. He simply runs out of book, and once the book ends he has no plan left to follow.

I was sitting at the table against the wall, in the shadow. From the flank corridor, I saw the whole game. What I saw was not a good game of chess. It was a collision between two kinds of players who coexist at club level: the ones who accept paying what I call the theory tax, and the ones who look for every possible way to avoid it.

The game in Tagansky is a speck of dust. But it leads to a product being promoted in chess circles lately: a six-video course by a Bulgarian International Master, designed to give Black a plan against the system openings White uses to dodge heavy theory. There are more layers to that product than an ordinary advertisement, and that is the part worth writing about.

What the theory tax is, and why it has a market

To understand why such a course has a place, start with the theoretical structure of 1.d4.

A game beginning 1.d4 splits into two branches. One is the main branch: 1.d4 d5 2.c4. The move c4 opens four enormous families: the Queen's Gambit Declined with its Orthodox line, the Slav, the Semi-Slav, and the Queen's Gambit Accepted. The Semi-Slav alone, with the Moscow and Meran systems, fills a shelf. At professional level, one move out of rhythm on move twelve can push the evaluation down by nearly a pawn.

The other branch is the systems branch: White delays or abandons c4 entirely, builds a stable piece structure, and plays to a plan. London, Colle, Torre, Trompowsky, Catalan, Richter-Veresov, Blackmar-Diemer. Here White does not need to remember thirty theoretical moves. He needs to remember one setup, a few exchange tricks, and a middlegame plan.

For a club player this is a straightforward cost problem. Someone with eight hours a week for chess will not spend all eight memorising Semi-Slav branches. He spends two hours learning the London setup and the remaining six on endgames. The result is that at club and intermediate level, the density of London, Colle and Torre players is far higher than the density of 2.c4 players, compared with the ratio at professional level.

That is why a product teaching Black to meet this group has a market. International Master Valeri Lilov, a Bulgarian, does not try to teach the full body of counter-theory. He teaches plans. Six videos, one group of openings each, plus extensions into the Catalan, the Blackmar-Diemer and the Richter-Veresov.

Each system, and the point where advertising separates from analysis

London System: 1.d4, then an early Bf4, Nf3, e3, Bd3, c3, Nbd2. The structure barely depends on Black's moves. White builds one block and waits. London's threat lies in the middlegame: once knight and bishop are placed, White can play Ne5 and push f4, or push c4 at the right moment. The weakness is that c4 is delayed so long that White usually accepts a narrower space advantage.

Colle System: 1.d4 d5 2.Nf3 Nf6 3.e3. The most classical system in the group, and the most underrated. The plan is clear: Bd3, c3, Nbd2, then e4 or c4 depending on the position. Its strength is the ability to shift from one structure to another without losing tempo, which makes it hard for Black to choose a direction of counterplay.

Torre Attack: 1.d4 Nf6 2.Nf3 e6 or g6 3.Bg5. The bishop comes to g5 early to pin the f6 knight. It is an irritating opening. It threatens nothing serious but forces Black to solve a specific problem before completing development.

Trompowsky: 1.d4 Nf6 2.Bg5. The bishop comes to g5 on move two, forcing Black to choose between taking the bishop pair and taking a bad structure.

Richter-Veresov: 1.d4 Nf6 2.Nc3 d5 3.Bg5. The knight goes to c3 before the c-pawn is pushed, then the bishop pins.

Blackmar-Diemer Gambit: 1.d4 d5 2.e4 dxe4 3.Nc3. White gives a pawn for tempo and an open file. At high level the gambit is considered insufficient compensation. At club level it is a deadly trap because Black usually does not know when to give the pawn back.

Catalan: 1.d4 Nf6 2.c4 e6 3.g3. I will come back to this one.

What the systems above share, apart from the Catalan, is that they sharply reduce the amount of theory White must remember. White trades theory for plans. That is exactly what Lilov's course targets: if White trades theory for plans, Black must trade counter-theory for counter-plans. Black does not need to know every branch. Black needs to know precisely what he is doing on move eight, move twelve, move fifteen.

That is a sound argument. It is also an argument an advertisement will inflate. The course calls this group of openings extremely dangerous. In my experience of watching, that phrasing is practically true but has no quantitative basis. London, Colle, Torre and Trompowsky are genuinely unpleasant at club level, because Black usually has no plan. At master level, nobody calls the London extremely dangerous. There, the London belongs to the group of openings Black can neutralise by playing the correct structure.

So two questions must be separated. Do system openings create a real practical problem? Yes. Are they objectively extremely dangerous? No, and the advertisement offers no metric to prove otherwise.

Six videos, eight topics, and the coverage problem

The structure of the course deserves close reading. Six videos cover at least eight opening groups: London, Colle, Torre, Trompowsky, Catalan, Blackmar-Diemer, Richter-Veresov, plus material against the avoided main lines. On average each group receives less than one video. For a complex system such as the Catalan, less than one video is very little. That does not make the course useless. It means the course prioritises coverage over depth.

If you have six videos and eight topics, you are selling a map rather than territory. For a club player the map may be enough. For someone aiming at 2026 Elo, the map expires after about three months, and at that point they must return to the very theoretical branch they were fleeing.

People watch pieces move. I watch the whole block shift. And the block here shifts in one very specific direction: from avoiding theory to paying for having avoided it, only later and at a different level.

Placing this product in the chess instruction market clarifies its position. At the top are courses authored by grandmasters, usually tied to a large platform and sold by subscription. In the middle are coaches holding IM or FIDE Master titles, selling standalone courses. At the bottom is free content on YouTube and blogs, where almost every minor variation has already been analysed by someone.

Lilov's product sits in the middle. It competes with free content on curation and systematisation, and competes with grandmaster courses on price. In a market this saturated with free material, the real competitive advantage lies in selection, not in raw volume of analysis.

The instructor's title also needs to be placed correctly. International Master is the second-highest lifetime title below Grandmaster. For a course aimed at club players, that is an appropriate level of authority. For a player preparing open tournaments at a high rating, it is not enough. The article supplies no rating and no tournament record for the instructor, so there is no way to verify depth of expertise beyond the title itself.

For a club player, the benefit of such a course is measurable. If you meet the London three times a month and each time lose twenty minutes thinking on move six, a prepared plan saves you roughly an hour a month, plus a large psychological edge: you enter the game feeling you already know what is coming.

But that saving only holds if the plan is correct. A plan that is wrong on move twelve will make you more confident and play worse, and that is the most unpleasant kind of loss there is.

The name in the headline and the name in the body

Here is the detail that stopped me. The headline of this product article is an interview with Timur Turlov. Across the entire content, from the course description, the instructor's name, the list of openings, to the promise of a Black plan, the name Timur Turlov does not appear once. No questions. No answers. No quotations.

Two possibilities. One, an editorial error in which the headline of an interview was attached to promotional copy. Two, sponsored content in which a sponsor's name sits at the top as a brand while the body belongs to a third party's product. Both lead to the same conclusion: the reader clicks looking for a conversation and receives a sales page.

The problem is not whether the course is good or bad. The problem is that every source in the article is one-directional. The favourable claims all come from the author or from the seller. There is no sample game. No ACPL figure. No database statistics. No win rate. No tournament name. No elite player named for verification.

For an opening analysis, missing data is missing everything. You can sell a plan in words. You cannot verify a plan in words.

There is also a technical inconsistency. The article frames the whole story around the line after 1.d4 d5. But the Trompowsky begins 1.d4 Nf6 2.Bg5, with no d5. The Torre begins 1.d4 Nf6 2.Nf3, also with no d5. The Catalan includes 2.c4, meaning it belongs to the very branch White is said to be avoiding. The article's logical scaffolding collapses at exactly this point. An opening taxonomy that does not hold up technically is a sign that the taxonomy was written for sales, not for teaching.

If a sponsor's name genuinely sits atop third-party instructional content, that is a notable pattern: private capital flowing into chess education rather than into elite tournaments. It shows the commercial value of chess at grassroots level, where the number of learners far exceeds the number of professional event viewers. That is an economic signal, not a sporting one.

What I got wrong

Seven months without football, seven months of asking why. In 2026, when every competition stopped, I built my own dataset of club-level games to test a prejudice of mine. The prejudice was this: system players are lazy, people who do not dare enter the real theoretical branch.

The dataset gave me a different answer. Most system players are not lazy at all. They allocate their time differently. They invest in structure and endgames. In many games they won not because Black was weak, but because Black was placed in a position where he had to think from move ten while the other side had already thought from move one. I had underestimated the value of plan-based preparation.

I made a similar error on a larger scale. In 2026 I predicted Argentina would be eliminated in the World Cup quarter-finals because their defence was thin. I watched the final live and saw where I was wrong: I underestimated squad depth and the coach's ability to read a game. That principle applies to the board too. Well-prepared plans can compensate for theoretical shortfalls, in football as in chess.

Patience is not stillness. Patience is waiting for the opponent's pressing rhythm. On the board, that rhythm is the moment Black is forced to think without the book. Whoever prepares for that moment wins. Whoever memorises without understanding it loses, exactly like the Black player in Tagansky.

And here is where I must separate two things the promotional article deliberately blends. The phenomenon is real: club-level White players are dodging the theory tax, and that creates genuine demand. The product is unproven: there is not one game, one metric, one rate with which to test the promise. A responsible writer must say both things at once rather than choosing one to make the piece tidier.

Systems do not lie, but they can only be heard when the data is thick enough. And the data in that product article is thin enough that I cannot use it to conclude anything about the quality of the course.

Looking to the next game

Next time, if I sit in Tagansky and see a Black player open a notebook on move six, I will not look at the notebook. I will look into his eyes on move fifteen, once the book has ended. And I will check one thing only: whether those six videos carry him past move fifteen, or merely deliver him there and leave him behind.

I am sixty-nine. I still learn from the young. Football does not retire, and neither does chess.
