Seven Openings, Six Videos, Zero Data: Decoding the 'Royal Road' of Club Chess

The original headline, read correctly, should be "The Right Royal Road" — a literal translation of the German idiom der richtige Königsweg. A translation engine ground it into "the right king road," and that detail alone was enough for me to reconstruct the document's provenance before reaching the second line: a product introduction, originating from a German-language chess shop or blog, re-promoting a commercial video course. No publisher name. No platform. No price. No date. I have tracked the opening-content market long enough to recognise the genre instantly — advertising copy, not reporting. Seven opening systems. Six videos. Not one line of data. The first number had already given the product away. CONTEXT: A machine that sells "plans," not "moves" The product is a video course presented by IM Valeri Lilov, a Bulgarian trainer. On its surface, it is a repertoire for Black against the 1.d4 systems I still call "the lazy player's weapon" — the Colle complex (ECO D04–D05), Trompowsky (A45), Torre (D03/A46), London (D02), Catalan (E00–E09), Blackmar-Diemer Gambit (D00) and Richter-Veresov (D01). The marketing frame is familiar: White lacks the ambition to play the main 2.c4 lines, so White avoids Slav, Semi-Slav, QGA and Orthodox QGD theory. In return, in the author's own words, they walk into "extremely dangerous" systems. That is the second contradiction, and it matters more than the translation detail. The same text calls White's approach "not very ambitious" and then calls it "extremely dangerous." In chess language those two sentences do not actually clash — but they only coexist if the reader understands the true nature of the danger. The danger here is not an objective White advantage. It is drift risk: White gets a riskless game, while Black, lacking the characteristic plan, quietly slides downhill as White accumulates. This product belongs to the "plans" tier, not the "moves" tier. Plans-based teaching is a legitimate pedagogical choice, even a superior one for the target audience. But it is "following the mainstream," not "opening innovation." There is no novelty claim. No engine analysis sample. No win-rate statistics. No ACPL. Nothing. To grasp the scale: a genuine "Lifetime Repertoire" on platforms such as Chessable must come with a GM co-author, engine data, and hundreds of variations. Here we have six videos and a promise. CORE ANALYSIS: The map of seven systems, and its geometry gap This is where I start placing bets. I never evaluate an opening course by its marketing copy — I evaluate it by its table of contents. And this table of contents carries a fatal classification error. The article frames everything as arising "after 1.d4 d5." The Catalan does not. The Catalan requires White to have played c4 and Black to have played ...Nf6/...e6/...d5 (1.d4 Nf6 2.c4 e6 3.g3 d5). That is a mainline, theory-dense opening — exactly what the article says White is fleeing. When you bundle the Catalan into an "avoid-the-theory" package, you mislabel one of the heaviest openings in the entire ECO E00–E09 range. The principle is simple: I bet on the numbers before the world knows how to read them. Here the number is seven systems divided by six videos. At least one video must bundle two systems, or one system is compressed. The most plausible candidate for compression — by theoretical weight — is the Catalan, or the Blackmar-Diemer, or the rarest pair. If I had to bet on the module treated worst, I would pick the Catalan. The second gap is a move-order problem. The proper Trompowsky (1.d4 Nf6 2.Bg5, A45) arises before Black commits to ...d5. A 1...d5-first move order produces a different, loosely named line: 1.d4 d5 2.Bg5. The umbrella framing "1...d5 + plans" inadvertently blurs a genuine move-order decision — one that any repertoire builder must resolve explicitly. The third gap is a mixing of strategic categories. The Blackmar-Diemer (1.d4 d5 2.e4) is a romantic gambit, a pawn sacrifice. Grouping it with the Colle and the London — two quiet, accumulating systems — blends two very different playing philosophies. One demands you seize the initiative; the other two demand patient construction. Learning them together is not wrong, but selling them as a uniform package is skewed. And here is the point I want to press hardest on the technical side: the difficulty gradient across the six systems is too wide for a single uniform product to be equally "sufficient" for all of them. The Colle (2.Nf3/3.e3), Torre and Blackmar-Diemer can be handled by plans plus a dozen concrete moves. The Trompowsky and London demand accuracy against early ...c5/...Ne4/...h6 ideas and against the dark-squared bishop trade. The Catalan demands an actual repertoire decision — the Open Catalan with ...dxc4 and ...b5/...Bb4+, or closed structures with ...Nbd7/...c6/...b6. The distance between "a dozen concrete moves" and "a repertoire decision" is the distance between a primer and a doctoral thesis. Data never lies, but it enjoys testing our patience. And here the only data we have — the ratio of seven to six — has spoken loudly. THE AUTHOR: One line of verification On IM Valeri Lilov, we have exactly two facts: the IM title and the label "Bulgarian trainer." No rating, no age, no activity, no results. In the online-course market, an author's title functions as a positioning signal: IM-authored courses typically target club level, while GM-authored and 2600-plus-tested repertoires aim at the 2100+ segment. The word "trainer" rather than "player" suggests the author's professional identity lies in coaching and content, not elite competition. If so, the course's authority rests on pedagogical clarity, not tournament results. That is an assumption I accept at medium confidence — and I flag it as an assumption, not a fact. The structural risk of the "prolific video author" model is that the presenter's practical experience may be second-hand — engine output re-narrated — rather than tested at the board. There is no data to confirm or exclude this. But the description "one plan for each opening" fits that product type entirely. CONTRARIAN: "Dangerous" is a feeling, not an evaluation This is where most readers will be led astray. The central claim of the promotional copy — that these systems are "extremely dangerous" and that "many players have painfully experienced" them — comes with no number attached. No sample game, no win rate by rating band, no engine line. It is a targeting device: the reader recognises himself in "many players," and the wallet opens itself. But be fair to the kernel of truth underneath. The pain is real. At club level, Black genuinely loses to the London System and Trompowsky without a plan. The problem is the exaggeration, not the existence of the pain. The danger here depends on the rating band. Below 2026, the claim holds. Above 2200, where concrete knowledge dominates, it weakens sharply. And at the top, these systems exist as one-off anti-preparation weapons, not as a career repertoire. Ironically, Lilov's product describes club reality better than elite reality — which is not wrong, only in need of being said clearly. I write from the conclusion, so here it is: if you buy this course expecting "revenge" against the London System, you will be satisfied. If you buy it expecting to understand the Catalan, you will be disappointed. Same product, two promises. SECOND CONTRARIAN: The repertoire economy is the real story The course itself does not deserve a long analysis. What deserves it is what it signals about the industry. The transmission map is clear. Upstream: IM-level video authors producing engine-derived plans at low marginal cost — AI-assisted scripts, home studio. Midstream: shops, blogs, affiliate funnels, where video courses compete with free explorer tools. Downstream: a shift in club-level opening choices toward low-memorisation systems. This chain is demand-pull, not supply-push. The club meta had already shifted toward low-theory systems — the "London-isation" driven by the streaming era and low memorisation cost — and teaching content followed that shift rather than creating it. The result is a self-cancelling paradox. The more Black players buy anti-London plans, the more White players switch systems, and demand for new courses is fed again. There is no bubble about to burst here; there is a durable niche that erodes the advantage of each individual product. The biggest industry risk in this segment is commoditisation. Free explorer tools, engine analysis, and AI-assisted course generation will compress the price of "plans" content over time. Pedagogy and tested experience are the only defensible differentiators left. A course built on "one plan per opening" sits precisely in the danger zone of that compression. In a content market flooded to the brim, data is the only audience left. This course offers the buyer no data with which to judge it. That is its most serious weakness, and also the easiest one to fix. SPECIFIC RISKS FOR THE BUYER Sorted by priority. First, undisclosed commercial interest. Every "fact" in the source is a vendor claim, with no platform, price, date, or independent verification. Handling: treat the entire text as advertising; check publication date, runtime, and platform before buying. Second, scope-versus-depth mismatch. Seven systems, six videos, and a Catalan carrying the theoretical weight of a mainline. Handling: assume the Catalan module is orientation-level only, and budget separately for a dedicated Catalan source. Third, the illusion of repertoire completeness. The "1...d5 + plans" frame excludes the 2.c4 mainlines by design, and apparently also excludes the Jobava-Prie London (1.d4 Nf6 2.Nc3 d5 3.Bf4) plus g3/Bg2 setups. The Jobava-Prie London is one of the most popular anti-establishment systems at both club and GM level in the modern era. Its absence is notable. Handling: audit the course contents against a full anti-1.d4 checklist before adopting it as a repertoire. Fourth, substitution risk. Free explorers and engines deliver most of the underlying information. Handling: buy only for the plan layer; do not expect informational exclusivity. Fifth, opacity of author credentials. Only "IM, Bulgarian trainer" is verifiable. Handling: judge the product by sample material, not by title. SIGNALS TO TRACK There are signals I will follow. Publication or update date: if undated or older than three years, obsolescence risk rises, especially for the Trompowsky and London lines. Depth of the Catalan module: if under roughly fifteen minutes of runtime, the scope-mismatch finding is confirmed. Appearance of the Jobava-Prie London and g3/Bg2 systems in the contents: if absent, the product's usefulness as a standalone Black repertoire falls materially. Frequency of London/Trompowsky/Colle at club level: if it keeps growing, demand for this category is reinforced. And the author's OTB activity on the FIDE rating list: if it stays quiet, the "tested at the board" claim weakens, though the pedagogical value does not. TAKEAWAY: Signals for the next cycle World Cup 2026 did not change the rules of the game; it only showed us a law that already existed. The opening-course market is the same. Lilov's "royal road" does not create a new law — it exposes an old one: when free content is already good enough for the information layer, the only thing left to sell is pedagogy, and the smart buyer pays for the plan layer, not the move layer. The gap I see in the market is a job with a clear shape: a complete anti-1.d4 repertoire, engine-verified, covering both sideroads and mainlines, and kept current. The window for it is the next twelve to twenty-four months, before commoditisation compresses prices across the segment. And for you — the one weighing whether to spend — you should ask a single question: are you buying a plan, or buying a promise? If the answer is a plan, and you play below 2026, this product may be worth it. If the answer is a promise, let the data — the thing absent from the entire promotional text — decide for you.
