Wednesday night, the page opened with a large claim about chess's future — “Chess is massively undervalued” — credited to a man named Turlov. Scroll down and the picture changes. The piece is not Turlov's. It is an advertisement for six training videos by the Bulgarian International Master Valeri Lilov. The headline sells one story; the body sells another. The old newsroom reflex lifts its head: the notebook says one thing, the tape says another.
A week earlier, in a club room at Purana Paltan, I watched the same scene inverted. On the White side, a Dhaka teenager rated in the 1200s quietly laid out the familiar London System setup. The man opposite him burned forty-five minutes inside fifteen moves. He did not know the next ten moves were memorised. The real fight in chess today sits on club boards, between memory and understanding.
Context
The chess boom that followed 2026 stopped being news a while ago — it is a market. Online platforms, streaming, and the quietest growing segment of all: instructional content. Courses, video series, monthly subscriptions. The customer is the player who loses at club level and does not know why.
My own ledger comes from a different place. I have watched Dhaka club chess for nineteen years, first from a print desk, later by phone from a digital desk in Bangalore. The picture I keep of the Premier Division Chess League belongs to no franchise. Police, Navy, Biman, the bank sides — a league balanced between clubs and day jobs. In March 2026 I was in Dhaka with the league running. Play stopped after round three, and the hall at Purana Paltan went dark for eighteen months. Round three is where that season stopped, not where it ended.
The picture changed when it came back. In the 2026 pre-tournament window, fourteen guest players were signed across nineteen days. Eleven of the twenty top-board seats went to imported Indian grandmasters. I did not file that as a scandal. I filed it as a ledger: standards up, local junior board-hours down. Read against that backdrop, Lilov's six videos raise one question — who is the buyer?
Core
The videos package a Black-side antidote repertoire against White's favourite systems: Colle System, Trompowsky Attack, Torre Attack, London System, Catalan, Blackmar-Diemer Gambit, Richter-Veresov Opening.

The list is the first problem, because these are not one family. Colle, London and Torre usually arise after 1.d4 d5 — White deliberately skips 2.c4, sidestepping Slav, Semi-Slav, Queen's Gambit Accepted and Orthodox QGD theory. Trompowsky, Richter-Veresov and Catalan usually arise after 1.d4 Nf6. Selling them together as an “after 1.d4 d5” package is a simplification, and simplification usually costs the buyer time.
The second claim is larger: these systems are “extremely dangerous.” Dangerous to whom? Not at elite level. At a 2700 table a well-prepared Black player is comfortable against them, and outside the London System most of them barely appear. The real danger band sits far lower, roughly 1500 to 2200. There the opponent arrives unprepared, and for a player who works eight hours and sits down in the evening, the opponent's memory is the sharpest weapon on the board.
The problem with Lilov's videos is not quality but evidence. Six videos, one plan per opening. No sample games, no engine match rate, no ACPL, no win-draw percentages. “The painful experience of many chess players” is an unsourced generalisation, not data. In the education market the trick is familiar: manufacture anxiety, then sell the cure.
One concession is due. Of the seven, the London System is the only member with genuine elite relevance. It has been used at the top level in recent years as a low-risk weapon, and that is probably the commercial engine behind anti-London products of this kind. The rest — Colle, Torre, Blackmar-Diemer — are essentially club weapons, or surprise tools.
This is where my own notebook has to come out. In more than twenty years beside club boards in Dhaka, the pattern is plain. A boy memorises the London, crosses 1800, then collapses at 2100 — because he never learned why the setup works or which move hollows it out. The system opening is not the culprit; the memorised system is. That gap is exactly what the course market wants to widen, not close, because memorisation sells and understanding does not.
The 2026 window belongs here. Nineteen days can change a club — fourteen signings, eleven of them foreign at the top boards. The day clubs start importing prepared grandmasters for board one, the local player's only remaining tool becomes the low-theory system, because that is what he can teach himself, what fits his means. The product, then, is a market signal, not a chess-strength signal.
One real signal does survive. The fact that niche-repertoire products — anti-London, anti-Trompowsky — keep launching means the population of low-theory White players is large enough to sustain them. That demand does not come from the elite table. It comes from club level, and a large share of club-level demand sits in South Asia, where coaching hours are scarce, study hours scarcer, and board hours scarcest of all.
Contrarian
The real story here is not the repertoire. It is how the repertoire is served. A quote — in Turlov's name — sits in the headline, and the body carries an entirely separate product. Nothing connects the two. In newsroom terms this is a sourcing failure: two unrelated things stitched together so that a name's aura rubs off on merchandise. Before buying, a player should ask a simpler question — who is Turlov, and from which interview, on what date, in what context, did that sentence surface?

There is also a pedagogical risk no commercial page will print. In the long run the system opening does not build a player's opening understanding; it narrows it. It works as a supplement, never as a substitute.
Takeaway
Two things are worth watching. First, if London usage at the top level continues, this product category will grow — and that growth is itself a measurement of club-level demand. Second, the Turlov quote needs checking against a primary source; otherwise it is a patron's story, not a product's story. And on the day that teenager in Purana Paltan touches 2100, we will know whether he got out of memorisation or stayed inside it.
