It was half past eleven at night. On a secondhand laptop in a bedroom in Mymensingh, a chess board glowed, and a paused stream sat in the next tab. That room is my studio. No press tribune, no commentary cabin, no chance to put a hand on a shoulder and ask what it feels like. Every round of the 2026 National Championship in Dhaka I watched exactly this way — without attending, opening PGN files and following move by move. From a Mymensingh bedroom, I learned the stadium is only a screen.

A screen has one great advantage: time. You can halt the game, rewind it, return to the same position three times. A reporter does not get that privilege. An analyst does. It was with that analyst's eye that I recently read a product description. It is not a tournament report. It is not a rules controversy. It is advertising for opening preparation. The instructor is the Bulgarian International Master Valeri Lilov. The format is six videos. The coverage is seven openings. The central sentence of the description is the real news: after 1.d4 d5, White's sidelines that dodge mainline 2.c4 theory — and Black's answer to them.
Reading that sentence, an old feeling returned. Batumi arrived to me through remote control, and the game became a signal I could pause. This product's claim is the same kind of signal. But a signal is not evidence, and that is the spine of this piece.
To grasp the subject, you have to hold in mind the reality of club chess here. In Mymensingh evening events and in Dhaka's club-based league, 2.c4 after 1.d4 has almost vanished in recent years. In its place come 2.Nf3, 3.Bf4, 3.e3, 4.Bd3, 2.Bg5, 2.Nc3. These are not the world of the Slav, the Semi-Slav, the Queen's Gambit Accepted or the Orthodox Queen's Gambit. For players who learned chess from YouTube videos and club chatter, these are the real openings.
One thing should be said plainly: this is not a course review. There is no data in the description to judge whether the course is good or bad. No specific move sequence, no sample game, no engine evaluation, no win-draw figures. Only claims. So my question is not whether to buy it. My question is how many problems the thing being sold — "system openings against 1.d4 d5" — actually contains.

The theory map must be drawn first, because without a map a claim cannot be measured. After 1.d4 d5, White's heaviest weapon is 2.c4. That branch gives birth to the Queen's Gambit Declined, the Slav, the Semi-Slav, the Queen's Gambit Accepted, and the Catalan. Black has half a century of accumulated theory there, books, databases, repertoires. If White enters, the game is largely a memory contest.
When White does not play 2.c4, the contest does not stop — the field shifts. Black cannot answer with a stored variation, because White has asked no mainline question. This is the tactical trap. By avoiding the main line, White has decided to play a plan rather than a memory. Black must reply in the language of plans too, and White is drawing the map.
Look at the inner structure of these sidelines and a pattern appears. In the London System White usually plays 2.Nf3, then 3.Bf4 or 3.Bg5, 4.e3, 5.Bd3 — White's dark-squared bishop leaves home while Black's dark-squared bishop gets buried. In the Colle, White plays 3.e3, 4.Bd3, 5.Nbd2 and later e4 — the same skeleton, a different order. The Torre Attack uses 3.Bg5, again trying to activate that bishop, but against a different target.
The Trompowsky (2.Bg5) and the Richter-Veresov (2.Nc3 and 3.Bg5) are a different kind of threat: White pins or harasses the knight on f6 from the very first moves, creating a psychological squeeze in which every natural Black move looks slightly weak. And the Blackmar-Diemer Gambit (2.e4) is a different animal again: White hands over a pawn immediately, buying open lines and attacking tempo. If the reclamation arithmetic works, Black wins quickly; if Black cannot calculate it, Black loses quickly. That is the gambit's eternal charm and its eternal risk.
Analysing the structure of all seven yields something the description never states. Seven openings are not seven problems; they are three families, with the Catalan a fourth and entirely separate creature.
The first family — the bishop-outside-the-chain family: London, Colle, Torre. All three aim at the same thing, getting White's dark-squared bishop out of the house and active, pressing along the b2-f6 diagonal. Understand one set-up and you can resist all three: Black typically strikes at the centre with c5 or e6, shuffles the f6 knight, and renders the bishop's target harmless.
The second family — the pin-harassment family: Trompowsky and Veresov. The first task here is psychological. Black must appear solid while being made to look weak, and that demands nerve. The correct answer usually involves a timely c5 or e6 counterblow in the centre and, if needed, moving the knight off f6, making White's bishop quietly irrelevant.
The third family — the reverse-sacrifice family: the Blackmar-Diemer. Here Black must be an accountant, not an aesthete. Without the exact order for returning the gambit pawn, White wins every time; with it, White suffers every time.
And the Catalan? Here lies a technical crack in the description. The Catalan almost always arises after 2.c4 — for example 1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.g3. The description's own premise is that White avoids 2.c4, yet the Catalan walks straight into it. Either an extra anti-Catalan section has been added — which would be a sound decision — or the summary is muddled. Either way, it shows why the buyer must verify independently rather than decide from marketing copy.
The ratio of seven openings to six videos now becomes meaningful. The most honest explanation for covering seven openings in six set-ups is that two openings share one skeleton. The likely pairing is inside the London-Colle-Torre cluster, since all three are different dresses on nearly the same pattern. This is usually the smartest way to teach: compress everything into a few patterns instead of counting separate lines. Call it a memory-light repertoire. From a Mymensingh bedroom, I learned the stadium is only a screen — and a screen is also where compression either works or collapses.
A memory-light repertoire is not a miracle cure. It has a specific failure mode. Such set-ups survive the opening and die in the middlegame, because recognising a plan and executing a plan are separate skills. Plan recognition can be learned from video. Plan execution is learned from annotated positions — where you can see that at move 25 someone is losing a tempo, or declining a trade.
Here I have first-hand experience. In December 2026 I wrote a 2,400-word breakdown of a Ziaur Rahman rook-and-pawn endgame from the National Championship, explaining the geometry of the "nouka" to readers who had never held a scoresheet. Around 40,000 people read it in a week. The lesson was simple: readers do not want moves, they want positions. They want to see a plan before they buy one.
That points to a structural gap in Bangla. There is no high-quality chess monograph in Bangla, no structured repertoire library, no annotated anthology of junior games. When I launched "Chal," a Bangla-language blog annotating games move by move, in 2026, this emptiness was the reason. Before buying an English course, a player deserves to know what a handful of positions actually mean in his own language.
The market deserves mention too. In the engine era, information is abundant; the scarce goods are time and attention. A player with three hours a week finds six videos attractive. A player with three hours a day finds them nearly irrelevant. The description never names a target rating band, and that is its largest gap.
An inference is not unfair, though: the London, the Colle and the Trompowsky are encountered most often in the roughly 1400–2200 club and online range. At elite level, 2.c4 remains the real battlefield after 1.d4 d5, and these systems are nearly absent there. So the product, if it wants to be honest about rank, is a club-level tool. The adjective "extremely dangerous" cannot be proven by any metric supplied.
A deeper problem hides here. Almost every modern broadcast carries a win-probability bar, an engine's green and red line. The benefit is obvious. The cost is not small either. When best move and best plan collapse into the same line, viewers stop learning to calculate in their own heads. The same data pipe — live evaluation, per-second statistics, probability modelling — feeds broadcasters, scouts and betting markets alike. The more open the data, the more both the insight and the commercial exploitation grow, and in chess that is true in a dangerous way.
In Bangladesh another layer is added: inequality of measurement. Niaz Murshed gave South Asia its first grandmaster in 2026, before Anand. India built a pipeline from school chess, sponsorship and institutional habit. We built a monument in Niaz's name. A seventeen-year GM drought, a ceiling of five grandmasters, a federation budget smaller than a bat sponsor's fee — these are not stories, they are arithmetic. Manon Reja Neer's national title at fourteen in 2026, and Niaz's title at fifty-nine in 2026, opened a window on that possibility again; we looked through it without ever redesigning the room.
Against that backdrop, the difference between a purchased repertoire and a built map matters. The 1500-rated boy in Mymensingh who plays evening events dreams of becoming Niaz or Ziaur. An under-18 player in Dhaka has a personal coach, club access, travel funding. Buying a course against system openings does not close that gap. Hours at the board, against the right opponents, do. The promotional texts rarely mention this asymmetry, because the small-town hero story sells better.
Now to the part where I dissent from the conventional view. First, let the conventional view stand at full strength. The course fills a genuine hole — agreed. When White avoids 2.c4 after 1.d4 d5, a blank region opens on Black's side of the map, a region the mainline books do not cover. The claim for system openings is also true: they hand a preparation-free player a lottery ticket, because White concedes nothing. An International Master is entitled to write the first sentence filling that hole, and the headline is credible.
The fracture starts there. First: behind "extremely dangerous" there is no sample, no rate, no engine comparison. It is not a useless claim — at club level these systems genuinely cut. But a sharp claim should be proven with data, not adjectives, and the description supplies adjectives. Second: the Catalan inconsistency shows the summary itself is not exact. If that is true at the level of the description, a student should verify rather than simply trust.
Third, and most important: Black's real obstacle is often not opening knowledge but the collapse of the plan under time pressure. A plan-based repertoire looks beautiful while the clock is calm. Near move forty, the plan breaks and the old habit returns. And that habit is usually the opponent's plan — the System player's plan. That is the executive blind spot. Buying a six-video course and quietly applying it in round four of a club Swiss are not the same thing.
Honestly, this gap stays unmeasured, because club players' results are not collected in any central database, not in public view. Many active club players have no rating at all; the national federation keeps no player-depth index. The effectiveness of any training product is therefore left to guesswork, because the instrument for measuring success does not exist. Call it an accountability deficit, or selling without measurement.
Chess has always played in empty stadiums. I wrote that in 2026, when the pandemic flattened the club and tournament calendar. The federation ran an online Olympiad; our players competed from bedrooms on domestic connections. That period taught me how heroic club-level streaming really is, and how few hands can make it happen.
In the coming season, the honest way to test this product is not counting videos. If in the next club event you can consciously carry that plan to move 25 — trades, pawn structure, the fate of Black's dark-squared bishop — the course worked for you. If your hands slide back into old habit under pressure, the problem was never the card. It was the screen.
And my own question is this: how many players in Dhaka club chess keep their own games on file, with results worth tabulating? Before buying another course, why are we not building a Bangla repertoire out of our own club positions — because a game with its answer attached can be played again, and that is something nobody can sell you.
