Theory Inflation and the Chess Course Market: Seven Openings Inside Six Videos

At two in the morning I opened a course page, and the first thing that stopped me was not a move — it was a headline. "Vlastimil Hort Tournament 2026: Return to Hotel Don Giovanni." Vlastimil Hort — the Czech-German grandmaster who once sat among the world's elite, a relentless competitor still keeping a seat by the board. The name lifted my mood; I thought the night had paid off, that I might find a round, a story, someone looking back at old days from a hall in Hotel Don Giovanni.

But scrolling down, I found not one round, not one player, not one result, not one move. Where the headline promised a tournament, the body carried an advertisement for a video course — six videos by International Master Valeri Lilov, teaching Black how to answer White's "avoidance" systems. That gap between name and content became the loudest signal for me. It exposes the question chess keeps dodging: how much room has theory taken, such that the art of dodging it has itself become a market?

I have watched this game for ten years — sometimes as a commentator, sometimes blowing dust off archives. What pulls me more than scorelines is the economics behind the board, and this page opened exactly such a door.

Context: the mainline nobody wants to play

To understand this, you first have to grasp an ordinary club-level truth. After 1.d4 d5, White's most respectable path is 2.c4 — the Queen's Gambit. But its real weight is so fearsome that playing 2.c4 forces you to face four vast theory-oceans: the Slav, the Semi-Slav, the Queen's Gambit Accepted, and the Orthodox Queen's Gambit Declined. The theory is so deep that even top grandmasters memorise it all their lives, and every year engines carve out new branches.

For a club player, that is an impossible race. So they sidestep it. They don't play 2.c4. Instead they play the London System, the Colle, the Trompowsky Attack, the Torre Attack. The charm of these systems is that they are not memory-based but plan-based. White learns less theory and more structure, and that simplicity often works over a club board.

This is nothing sudden to me. Nobody who watches club chess can deny what the London System's rise has done over the past decade. I have sat through many weekend tournaments and seen it — in the lower boards, White players seem to have quietly reached the same decision: less theory, more structure. That is the soil in which courses like Lilov's grow.

Core analysis: six videos, seven names, one gap

The course announcement says six videos build Black a complete plan — a separate plan for each opening. But the announcement contains its own inconsistency. Seven systems are named: the Colle, the Trompowsky, the Torre, the London — and then, at the end, the Catalan, the Blackmar-Diemer Gambit, and the Richter-Veresov. Six does not match seven.

This may not be mere miscounting. The likeliest explanation is that one video bundles two or three closely related systems — the Colle and London are near-siblings, sharing the same Bd3-Nf3-e3 formation. Or the promotional number was simply rounded. Either way, the gap is the first signal that the information needs verification.

A larger problem sits in the classification. The announcement calls the Colle, Trompowsky, Torre, and London "not ambitious but extremely dangerous." For the London and Colle, that is fair: patient, low-risk, stable systems. But place the Catalan and the Blackmar-Diemer Gambit on the same list and things fall apart.

The reason is clear. The announcement's whole framing rests on 1.d4 d5, White declining 2.c4. The Catalan does not arise from that framing at all — it comes from 1.d4 Nf6 2.c4 e6 3.g3. The Catalan lives inside the Queen's Gambit family, not outside it. A course claiming to answer White's avoidance systems looks odd listing a system that stays home.

And the Blackmar-Diemer Gambit? It is the most aggressive line named — 1.d4 d5 2.e4, a direct pawn sacrifice. Grouping it with the placid London under one "unambitious" umbrella is technically incoherent. Anyone who has played the BDG knows it is a weapon to ruin an opponent's sleep, not a patience powder.

This is not small to me. When an instructional product's classification is at least self-contradictory, the buyer should check it. Here lies the course's biggest lesson: learn to ask questions before buying.

What is genuinely good

After all this criticism, I will fairly concede one thing. Plan-based teaching is the correct method for these systems. This is my belief, not mere praise of the course.

Think about it — the London is won by clamping the kingside with Bd3 and Ne5; the Colle by the e4 break; the Trompowsky by the early activity of Bg5. These are not forced sequences but structural understanding. So a course that teaches plans rather than memorisation matches its material. There is no Slav-scale syllabus here, nor should there be.

From ten years of observation: in club chess, those who play avoidance systems are usually two types — those who genuinely love simple structures, and those fleeing theory-fear. For the second group, plan-based instruction is the greatest help. But that help becomes real only when the player understands the idea behind each line, not merely copies it.

Contrarian angle: the real story is not the course

Here I want to stop somewhere else, because the easy reading is "this is a weak course." I won't say that. My view is that the real story is not this course but the system that made it possible.

Consider how theory inflation has grown so large that the product now exists on two tiers. Above — premium grandmaster masterclasses, teaching the deepest branches of the mainline. Below — exactly this kind of product, teaching how to avoid the mainline. Both tiers are born of the same demand: chess is now so theory-heavy that an ordinary player must learn the art of avoidance just to keep the game alive.

To me this is the story of the Queen's Gambit's weight rather than its beauty. The deeper a line grows, the more people want to walk past it. And every new masterclass, every new engine discovery deepens it further — so demand for avoidance products grows too. A self-driving loop, and Lilov's course is its latest visible marker.

Notice one more thing. The course's authority rests solely on the presenter's title — International Master. That is a real credential, one tier below Grandmaster. But it does not measure current strength. No rating, no recent results, no evidence of student success, no database-verified analysis. Authority rests on title, not proof — a weak promotional habit I have seen many times.

Yet there is a fair point here too. Such avoidance systems are really a coaching-level subject. For a club Black player, an experienced IM trainer who has taught these structures is often more relevant — he has caught the common mistakes a super-GM never faced. So the title is not enough, but it is not irrelevant either.

Where the buyer's real risk lies

Let me be clear. This product carries no competitive risk, because it is no player, no tournament, no governance event. It is an ordinary commercial instructional product. So no game-related risk question arises.

Then what is the risk? Information risk. First — the headline-body mismatch. When a headline speaks of a tournament but the body advertises a course, a gap opens between expectation and delivery. This is not a fairness question but a promotional technique — an easy way to capture tournament-related search traffic. The reader should treat the headline as non-informative and trust only the body's list.

Second — the absence of data. Not one game, not one engine evaluation, not even a metric like average centipawn loss. The promotional text offers no independent way to judge the course's quality. So before buying, any claimed plan should be cross-checked against a database or engine.

Third — numeric and classification inconsistencies. Six videos versus seven names; the Catalan and BDG misfitting the stated framing. Individually harmless, together they tell the buyer: know the exact scope before purchase.

I say this as someone who has wasted time on such pages many times, and also genuinely learned from exactly this kind of course. Both are true.

Why this story is familiar to me

Born in Singapore, raised between two cultures, working from India. I have spent years combing South Asian chess archives. That taught me one thing: a file or a page always says more in what it hides than in what it states.

Think of Bangladesh's chess economy. A small country, a handful of grandmasters, and year after year one question — where is the next grandmaster? I have written many times that this is not a talent drought but a patron drought. Theory's vastness never even arrives there, because the game stops before it — there is no training structure. And at the opposite end, this course shows theory has grown so abundant that a separate product must be built to flee it.

Hold both pictures together and an uncomfortable truth emerges. India built so large a theory market because thousands of players sit at boards weekly, tournaments are countless, coaching is a livelihood. But where Bangladesh sits, coaching still depends on individual charity. A country that could not build the structure to teach the mainline is far from the art of avoiding it.

So this page puts me before a question I have asked many times in my career: when chess knowledge becomes a product, who can buy it, and who falls behind? Between the player who can pay for six videos and the one who cannot, the gap is not only income — it is the future of talent.

What marks good coaching

How do you recognise a good course? I think by three things. First — it teaches plans, not sequences. Second — it is honest about scope, not over-promising. Third — it teaches the player to think freely at the board.

This course likely meets the first condition, being plan-based. But the second and third cannot be verified, because no evidence is given. And here I stop, because criticism has a limit: what is not given cannot be judged.

One addition. Learning avoidance systems is not weak chess. It is a smart decision if your time and energy are limited. Not everyone must dive into Slav theory. But the danger is this — if the plan is not fully internalised, these systems become harder in low time. You forget a memorised line, but a plan you half-understand is dangerous. Rapid and blitz make this plain.

The archive's lesson

For years I have kept a habit — with any new story or result, I hunt the history behind it. So this page handed me two real figures.

One — Vlastimil Hort. The name is placed only to catch traffic, but the man is real. A Czech-German grandmaster who held elite chess for decades and later became a familiar commentator. The headline uses a real name, but it is not linked to the product.

The other — Valeri Lilov. A Bulgarian International Master better known in the industry as a trainer and content producer than as a competitive player. His commercial value hangs on instruction, not live rating. That is no fault — it is honest labour. But remember: authority in such products is measured by the presenter's recent results, not title alone.

I recall 2026, the 44th Chess Olympiad in Chennai, covering Bangladesh's team, writing in the press room that Bangladesh gave the subcontinent its first grandmaster in 2026, while India built eighty-plus on the same idea. I understood then that chess is really a story of capital and structure. Today this course page brings me back to that truth from another side.

The industry flow: who gains, who does not

Consider where this product sits in chess's industry. Upstream — youth training and talent supply. Midstream — events, players, platforms. Downstream — content, commerce, derivative markets.

This course lives in the lowest layer, content-commerce. It turns chess demand into money — not through events or platform engagement, but through the demand for opening understanding. It is a long-tail instructional product feeding the coaching sub-market. Its impact on platforms, sponsorship, or events is near zero.

The commercial logic is demand-driven. The deeper the mainline, the more players buy answers to the shortcuts. A self-reinforcing loop forms between theory inflation and instructional supply. And such products usually earn through subscription bundles or a streaming/coaching platform, not one-off sales — though the promotional text never states the channel.

Warning signals to track

As the instructional content market grows, it needs transparency. The course's plans should be checked against current engine practice; if they diverge from mainline plans, that is a quality risk for buyers. The exact scope should be clarified — does the six-versus-seven mismatch resolve? And the frequency of club-level Queen's Gambit avoidance should be tracked — that demand decides such courses' fate. The presenter's rating and credentials should be verified, because authority hangs there.

A folder nobody opens

Finally, one thing worries me most. The chess industry's question is no longer that theory is too much, but that the people behind that theory are fading from view. We memorise, buy, watch videos, yet forget — behind this knowledge was someone's labour, someone's night at the board. An instructional product's value becomes real only when it makes a player freer at the board, not merely more memorised.

I have written this game's stories for ten years, and each time I understand — chess is not a contest of theory but of attention. A course that teaches moves may help. But a course that teaches you to see the idea behind the move sets you apart. Six videos cannot hold seven openings, but one right question can hold a lifetime.

And the question is: are we teaching chess, or only selling its fear?
