"Chess is something magic" — I stopped at the headline. It was raining in Penang that evening, the tin roof over the veranda drumming softly, and on my laptop screen a promise of an interview was rising into view. The name was Timur Turlov. I assumed someone was talking about chess patronage, and that the word magic was being used in that sense.
The page took seven seconds to load. Seven seconds later a training package was sitting in front of me: six videos, authored by International Master Valeri Lilov, on the subject of a Black repertoire. There was no magic in it — two columns of description, a purchase button, and a certain urgency to buy now.
The moment was not unfamiliar to me. In 2026, in the sixty-third minute of a Malaysia Youth Cup group match against Selangor, the ligament in my left knee tore. The whistle blew, and my knee learned a language no box score could ever translate. Through nine months of rehab, sitting in a room in Penang, my Dhaka-born grandfather taught me to read a board the way I had read a pitch. I have watched from the sideline until the game became a sentence I could finally edit. When the headline and the thing on the page do not match, that editing job is jammed at the first step.
So what is the picture here? The package is a defensive repertoire for Black. The attacker is White — the player who plays 1.d4 and refuses to offer 2.c4. The reason is simple: 2.c4 walks into the enormous theory library of the Slav, the Semi-Slav, the Queen's Gambit Accepted and the Orthodox QGD. At club level many White players dodge that library by choosing the London System, the Colle System, the Torre Attack or the Trompowsky Attack. These are the so-called anti-theory systems — structure in place of theory, habit in place of memory.
Lilov's six videos aim at exactly that territory. The promise is a relevant plan for Black against each of them. Added on top come the Catalan, the Blackmar-Diemer Gambit and the Richter-Veresov Opening. The author's identity amounts to this much: a Bulgarian trainer, an International Master — the tier just below Grandmaster. And Timur Turlov, named in the headline, is linked to none of this in any information point. There is effectively no bridge between headline and product; what exists is ornament.
The first question is straightforward: are these openings really extremely dangerous? The claim being sold hardest — that these systems are extremely dangerous — is not a finding of analysis, it is the architecture of a pitch. In statistical terms the London, the Colle, the Torre and the Trompowsky are lower-variance than mainline QGD play. Their aim is not an opening advantage; their aim is a safe, structured middlegame. A player who chooses the London with White is making a risk-reduction decision, not an attacking one.
The accurate technical sentence therefore reads like this: faced without preparation, these systems are annoying; played accurately and neutrally, they are not objectively dangerous. Annoying and dangerous are not the same word — one involves morale, the other involves valuation. To raise the price of a defensive product you have to turn annoying into dangerous. That is what happened here.

The variance question runs the other way inside. Mainline 2.c4 theory is informationally very heavy, but it is not result-extreme: with correct play from both sides the draw tendency is high. The London, the Colle and the Torre are informationally light on both sides, but White gets nothing from them either. White is left holding structure, Black is left holding plans. The danger, then, is not to White — it is to Black's lack of preparation. That is the risk of ignorance, not a risk on the board.
Still, the technical work genuinely exists, and going deeper makes the picture clearer. In the London System White typically builds a continuous structure with d4, Nf3, Bf4, e3, Bd3 and Nbd2, then pushes e4 into the centre. Black's practical answer rests on three pillars: a firm wall with...d5 and...e6, pressure on d4 and b2 with...Nbd7 and...Qb6, and most importantly the well-timed...c5 break. If Black delays...c5, White's e4 push lands and the board tips toward White's wishes.
The story in the Colle and the Torre Attack is much the same, except the shield comes forward. White presses the centre with Bg5 and e4 and dreams of parking a knight on e5. Black's established antidote:...e6,...Bd6 in a way that offers the dark-squared bishop trade,...Nbd7 keeping e5 under control, and the...c5 break that puts the question to e4 first. While White is finishing the setup and hunting for attacking chances, Black is breaking the structure and dragging the game toward clear equality.
The Trompowsky Attack (2.Bg5) is a slightly different puzzle. White pins the f6 knight, but Black has...Ne4 — a move that plants a knight in the centre and puts the bishop-pair question back on White's shoulders. Then...c5 together with...Nc6 gives Black a share of the dark squares. White's f3 kick takes time, and while it is coming, the...Nxd2 option in Black's hand becomes real.
Now the Catalan. This is my principal objection. 1.d4 Nf6 2.c4 e6 3.g3 d5 4.Bg2 is not a club sideline; it is a fully fledged mainline, containing the broad chains of...dxc4,...b5,...Bb7 and...a6 and long strategic battles in closed structures. Bundling it with the London is not possible, because its information load is two to three times heavier and its plans are of another kind entirely.
The Blackmar-Diemer Gambit and the Richter-Veresov Opening are no more of the same class. The Blackmar-Diemer is a semi-sound heroic attempt; facing it requires knowing specific forced lines of a sacrifice, not a general plan. The Richter-Veresov is a rare sideline; the problem there is not risk, the problem is surprise.
A single plan template cannot solve two different defensive problems: one group dodges theory with systems (London, Colle, Torre, Trompowsky), the other chooses theory-heavy or gambit-dense paths (Catalan, Blackmar-Diemer, Richter-Veresov). The first group is beaten by accurate equalisation, the second requires concrete preparation. Answering both with one structure is a conflict of purposes.
The numbers speak too. Seven openings, six videos. Give the Catalan the depth it deserves and there is barely exploration left for each sideline. Covering Catalan main lines and five sidelines in six videos is impossible in depth. Even if the titles treat the Catalan as a separate expedition, what remains for the other six is signal, not substance. That tells me the videos will most likely deliver plans rather than forced variations — pawn structures, piece placement, typical break timings. For memory this is extraordinarily efficient, because Black's setups converge on a few interchangeable structures such as the e6/d5 wall, in which...b6,...Bb7 and...c5 are all part of one sentence. But in the closed structures of the Catalan precisely that generic wall may leave tactical holes, because there each side is preparing not one square but a syllabus.
And here something missing becomes visible. None of this is independently verifiable. Who the sources behind the videos are — unstated. Almost every factual sentence carries a source field reading none; the claims themselves lack back-data. Yes, the interview headline loaded, but the only verified fact here is that it loaded for you. What you are looking at is not editorial, it is advertising. The mismatch between headline and content is therefore not an anomaly but a pattern.
Back to a familiar scene. On the club boards in Penang this year, at ratings between fifteen hundred and nineteen hundred, the most common setup I saw was the London. One young man walked that setup for thirty moves and then won off a pawn weakness born of White's error. At the next table, thirty minutes of blitz, the same London — and he lost, because...c5 arrived on time. The difference was not some mysterious attack; the difference was a calculation of probabilities, of who opened the centre first.
This is where the central argument sits. The author calls White's choice not very ambitious. A more measured sentence: this choice is famous not because it is lazy but because you cannot out-prepare the giant with a giant's toolset. The old friend across the board wants to attack, but he has no trainer, no hall, no regular coaching. Slav and Semi-Slav theory cannot be carried without planning, so he takes the London. The London is not a matter of temperament; it is the rational answer to scarcity. Where there is no coach, the student does not reach for simplicity — he reaches for a way to survive. And those who mock that simplicity as laziness almost always ignore the economics that pushed him toward it.
Bring Bangladesh into it and the arithmetic gets starker. My own count puts the Bangladesh Chess Federation's entire annual government grant at roughly eleven lakh taka — smaller than a single franchise cricketer's bat deal. At the end of 2026 I spent two weeks in Dhaka covering the Premier Division Chess League and watched Police, Navy, Biman and the bank teams hire Indian grandmasters as guest boards; one signing was reported at one and a half lakh taka. An entire club budget for one board. That league taught me that chess here runs on favour ledgers, not contract ledgers — and that the favours leave traces. Since then my rule has been: first ask who paid for this board, then ask who won. That method fails against this video advertisement, because there is no board, no number, no source there — only an endless market.
The market is not without its own crises. In 2026, locked in a student residence, I wrote about empty stadiums and full servers. The same thing was happening in chess: clubs closed, and the light moved from boards to servers. Not in daylight — three Dhaka International Masters were playing blitz at two in the morning, because the board was then the only room in the city with its door open. The number from those days is still in my notebook: the federation's annual government grant, under twelve lakh taka. That January I thought new coaching capital might arrive out of those two-in-the-morning boards. It did not. What arrived instead was the urgency of a video advertisement.
This is where personal experience does the most work. From those late-night interviews I learned something about format: one video, one signal, one living conversation — when those cost ten taka instead of a hundred and fifty, the honest question is whether I am being coached or sold a product. And someone who buys a variation-based product at a fourteen-hundred rating is skipping an intermediate step: without patterns the plan cannot be understood, and without the plan the patterns never form. Lilov's videos assume a prepared mind — one that already has experience of the d5/e6 structure. That does not make it a bad product. It makes it a conditional product, and the marketing hides the condition.
Not everything should be thrown away, though. The very market trend for this kind of defensive repertoire is a signal. It does not mean the London is fearsome; it means that at club level the London and its cousins are durable, and inside that durability a whole market sits quietly. What elite chess journalism never shows can be found in the aggregate search demand for these defensive products: the world's top twenty may play an eleven-move Sicilian, but the world's top two hundred thousand play the London. That gap between the two worlds is the real story here, not the product.
In closing, I have only one rule about training, and I learned it in rehab: the best columns are built like a rehab plan — small steps, honest pain, no shortcuts. One video series will not solve your London problem. Face one of these four systems twice a week for ten weeks and you will feel the change — that is scientific, not a defensive product's prescription.
## The closing question In chess history Niaz Murshed's 2026 feat came a year before Anand, and Rani Hamid carried the Olympiad board for decades; in December 2026, fourteen-year-old Manon Reja Neer won the National Championship undefeated. In a pipeline that shows long drought and occasional seepage at once, a boy is either entering a beautiful game or a beautiful marketing funnel. In 2026 our attention belongs half on the board and half on the training market. And one ratio deserves watching: six against seven, and one headline. The headline talks of magic; the actual board walks on, the way Neer and Rani Hamid walk on. Instead of the sweet headline hanging in the corridor, we should look at which board, and which two-in-the-morning light, stands behind each training video.
