Six Videos and the 'Theory Tax': When Marketing Crosses the Chessboard Line

In the back row of a small chess club on Pokrovka Street, Moscow, I watched an amateur game one Wednesday evening. White pushed the pawn to d4, then brought the bishop to f4 — the London System. Black, a student of about twenty, scratched his head. He had not gone wrong on move three or move five. He had gone wrong because there was no plan in his head at all. Twelve moves later, White clamped down on the centre, and Black sat waiting to be squeezed square by square. He did not lose because of opening theory. He lost because he did not know where to place his pieces. From the sideline, I see the whole game. What analysts call the 'theory tax' of the main lines — the Slav, the Semi-Slav, the Queen's Gambit Accepted, the Queen's Gambit Declined — is driving thousands of amateur players away from 2.c4. They choose system play to save time. And that very gap creates a market. To grasp why this story matters, we must place it on the right layer of the board. At elite level, 1.d4 followed by 2.c4 is almost a rule. The main lines of the Queen's Gambit demand that a player memorise hundreds of variations, many stretching twenty moves deep, with complex piece manoeuvres and distinctive pawn structures. For an amateur with a few hours a week, that tax is too expensive. So a large share of players take another road. They play the London System, the Colle System, the Torre Attack, the Trompowsky, the Richter-Veresov. These are 'systems' rather than 'variations' — built on plans rather than memorised moves. Such players are often modest in theoretical ambition, yet deeply irritating in practice, because the opponent handling Black rarely has matching preparation. This is precisely the ground that IM Valeri Lilov, a Bulgarian player and coach, targets. He presents a course of six videos designed to give the Black player a concrete plan against each system. The list the product walks through is long: the London, the Colle, the Torre, the Trompowsky, the Catalan, the Blackmar-Diemer Gambit, the Richter-Veresov, alongside the lines players avoid — the Slav, the Semi-Slav, the QGA, the Orthodox QGD. The appeal of the pitch lies in the fact that it touches a real wound. When a club player has Black against the London System, he does not lack moves; he lacks a route. Knowing whether to place the pawn on c6 or e6, which bishop to trade, which file to open — that is worth more than reciting ten opening moves. A clear plan can flatten a gap in strength across the first thirty moves. But hold on. People watch the players run; I watch the whole block of the formation shift. And when you look closely at the structure of the product, cracks begin to show. The first crack is taxonomic. The pitch frames the entire problem around the cluster 'after 1.d4 d5'. But the Trompowsky Attack — 1.d4 Nf6 2.Bg5 — never arises after 1.d4 d5. Neither does the Torre Attack — 1.d4 Nf6, then Nf3 and Bg5. And the Catalan, the positional system with 1.d4 Nf6 2.c4 e6 3.g3, actually includes the very move 2.c4 players want to dodge. The arrangement shows a framework built to sell, not to analyse. It lumps everything 'not main line' into one bag, regardless of different roots. The second crack is structural. Six videos for at least eight distinct opening systems is a telling ratio. If each video runs a normal length, each system receives a very modest span of time — enough to sketch a plan, not enough to handle sub-variations, unusual moves, or structural transformations. The product promises breadth of coverage, but depth is capped by design. For a beginner, that may be acceptable. For anyone aiming to improve at a higher level, it is a ceiling. The third crack is the one I watch most closely. The extracted information shows the product attached to a name in the headline — Timur Turlov — but that name appears in none of the information points in the body. Conversely, the coach Lilov's name never appears in the headline. The title and the content belong to two different subjects. This is a trust problem, not a chess problem. In the content trade, I have learned one thing: the system does not lie, but it can only be heard when the data is thick enough. Here the data is too thin to conclude anything about the product, yet thick enough to conclude something about how it is presented. The fourth crack concerns sourcing. Many of the selling points — 'extremely dangerous', 'help with six instructive videos' — come from the vendor or the writer, with no independent data behind them. There is no ACPL figure, no win-draw rate from a database, no sample game to verify the plans. For an opening product, that is precisely what should be there. A plan that sounds reasonable on paper can collapse under the pressure of engine calculation. The system does not lie — but the seller can exaggerate. My first piece got stoned. Data never takes offence. In 2026 I wrote a long analysis of RB Leipzig's gegenpressing and the Russian online community called me a conservative. I did not argue. I spent six weeks rewatching footage, logging 412 failed pressing situations, then published a correction with figures. Since then I keep one rule: hypothesis, verification, conclusion. Never assert anything absolutely about a new tactic. And Lilov's course deserves exactly that treatment: as a hypothesis, not a truth. So why does a product with such cracks still hold analytical value? Because it exposes a larger reality about the chess content economy. Titled coaches who have not reached grandmaster level are monetising the very gap the 'theory tax' creates. They do not compete with the vast opening courses of grandmasters. They compete with free content on YouTube and blogs. In that fight, the edge lies not in analytical depth but in curation, in branding, and in distribution. Seven months without football, seven months of asking why. In 2026, when the pandemic stopped every tournament, I stopped too and asked how this industry actually works. I compiled a dataset of 214 goalless draws from five top European leagues between 2026 and 2026, classified by nine pressing models. When football returned, my first article on how empty stadiums affect pressing tempo drew emails from three Premier League clubs. That lesson applies directly here: real value lies not in making big claims but in building data thick enough that no one can pick it apart. Lilov's course, in that sense, is an honest example of how this market operates. It does not deceive at the technical layer — the systems named are real, and Black's need for a plan against them is genuine. It only inflates at the marketing layer. The line between instruction and advertising is blurred, and the reader — and the buyer — is the one who must redraw it. What I want to stress is a paradox. The more opening content is produced, the less each piece is worth. When every system has an explanatory video, competitive advantage no longer lies in owning information but in knowing which information to choose and which to discard. Course buyers do not pay for knowledge — knowledge is free everywhere. They pay for curation and for the reassurance that someone has done the filtering for them. Patience is not stillness. Patience is waiting for the right rhythm of the opponent's pressing. For the amateur chess player, patience is waiting for the right moment to invest time in one system instead of leaping from course to course. One deeply understood plan can be stronger than ten plans skimmed through. And here is what I got wrong in the past, to be blunt. In 2026 I predicted Argentina would exit the World Cup at the quarter-finals because their defence was thin. I was wrong, and I had to write a 4,800-word self-criticism analysing exactly what I had underestimated: the depth of the bench and the coach's ability to read a game. I mention it here not to talk about football but to explain how I treat Lilov's product. I do not call it worthless. I simply refuse to call it complete. Moscow 2026 — people remember the goals, I remember the space in the right corridor. So it is with opening products: people remember the flashy names in the headline, I remember the mismatched details in the body. Timur Turlov appears in the headline and vanishes from the content. Lilov instructs in the content and is absent from the headline. It is a small detail, but small details are where the machine's workings are most clearly exposed. A word more about the name Turlov itself. Beyond this article, in circles close to chess, Turlov is known as a financial figure linked to chess sponsorship. If that is right, his appearance in the headline may be a sign of a sponsored piece, where a personal brand serves as the hook for someone else's educational content. I mark this claim at low confidence and it needs independent verification. But it opens a larger question for the whole industry: where is sponsorship money flowing in the chess content chain, and is it shaping what fans read? I am sixty-nine. I still learn from the young. Football does not retire, and neither does chess. The lesson worth taking from this story is not in the six videos but in how the content market is reshaping the game itself. The question is not whether this course is good. The question is: when every opening secret can be bought for a few hours of video, what skill actually remains? And are buyers clear-headed enough to recognise that what they are purchasing is not knowledge, but the feeling of being guided?
