On the board, only a pawn has moved. a7 to a5 — two squares, one file. Nothing above it, no threat, no capture. To a spectator who does not play chess, it looks like a wasted pawn move; to anyone who plays the King's Indian Defence, it is a declaration. White is about to take space on the queenside with the b-pawn, and Black has narrowed that space in advance.

I am writing about a single move because a training DVD has landed in front of me like two separate documents stapled together. On the cover, Capablanca, and a line about the individual gold medal on board one at the 2026 Buenos Aires Olympiad. Inside, something else entirely: a King's Indian recommendation against White's Bayonet Attack — 9...a5.
A headline is a promise; the body is its ledger. When the two do not reconcile, one of them is usually not true.
The DVD does not name its author. It gives no rating, no record in the line, no engine version, no sample games, no database statistics. It gives a sentence: this move solves the computer-era problem. That sentence may be true. But a sentence cannot occupy the place of verification, and in the chess market it is precisely sentences that sell.

I began writing on the sports desk of a Dhaka newspaper in 2026, the year Niaz Murshed became Bangladesh's first grandmaster — a full year before Anand. We had no engine, no online database, no rating server. We had a notebook and a pen and one question written beside every move: what was this move bought for? Today the question has changed. Now it is: how much did this move sell for? This piece is an attempt to put the first question back in front of the second.
The Buenos Aires Olympiad ran from 21 August to 19 September 2026. On 1 September, German forces crossed into Poland. Outside the hall the world was coming apart; inside, pieces kept moving. Many players never went home, staying on in Argentina because the ships and the borders had closed. Capablanca took the individual gold on board one in that tournament — a tournament whose results are preserved and whose politics and labour nobody has audited. A historic gold, a war, and a DVD cover can all be placed in one sentence, because the market always remembers history and always leaves the present unaudited.
Back to the board. In the Classical and Mar del Plata structures of the King's Indian, White's sharpest practical plan is the Bayonet Attack, 9.b4. The move looks simple and its logic is merciless: prepare c5, take queenside space, nail down Black's c7-pawn, and then lean on the d5 square.
The acknowledged main road is 9...Nh5. The knight threatens f4, prepares...f5 and...f4, and binds the kingside attack into a chain of forcing moves. That forcing character is both its strength and its weakness. Where moves come almost automatically, preparation means memorisation, and in a memorisation contest the better computer wins.
That is where the DVD's commercial logic begins. If 9...Nh5 leads to a forcing line where a well-prepared White is deep, why should a club player enter it? Hence 9...a5: stop the queenside first, so that Black can run the...Nh5/...f5/...f4 programme without worrying about b4-b5.
The technical argument is sound. a7-a5 makes White's b4-b5 thrust less relevant; if White pushes anyway, Black has...c5 or...a6-based counterplay; and Black can complete the standard kingside build-up undisturbed. It sits in the ECO E97–E99 band — adjacent to the main road, not on it.
9...a5 is neither a novelty nor a refutation; it is a prophylactic device that buys Black time and quiet for his own attack.
Had the cover said that, this article would not exist. Instead it says antidote, solution, remedy for the computer age. In marketing language those are selling words; in technical language they are claims. Claims require evidence, and there is none.
What an opening product should minimally disclose: the author's name and his record in the line; at least a dozen complete sample games with dates and events; which engine version, at what depth, on what hardware; the win-draw-loss ratio of the structure over how many games; and an explicit list of lines not covered. Without these, what is being sold is not preparation but confidence.
My professional habit interferes here. In 2026 I sat with a headset for a streaming platform at the FIDE World Cup in Tbilisi — a 128-player knockout over 25 days, no studio, no producer, a laptop and a chat window scrolling faster than I could read. The deadline was every four seconds. When Levon Aronian finally broke Ding Liren in the rapid tiebreak, I was answering a schoolteacher from Khulna about why a king cannot be captured. That taught me something durable: what an audience asks for is not the result, it is the reasoning, and the first condition of reasoning is to name the source.
The second problem is larger. The DVD revives an old complaint: computers often cannot handle complex strategic positions. Before 2026 that was defensible. Since 2026 it is not. Neural-network engines, Leela-type evaluation and NNUE-class tools read closed structures with remarkable reliability. The closed King's Indian is now one of the deepest prepared areas in chess, precisely because human and machine speak the same language there.
The claim that computers do not understand these positions is no longer technical information; it is nostalgia packaged as a product feature.
Then there is the time-control question. The low-theory selling point works best at classical controls, where understanding compounds over a long game. In rapid and blitz it reverses. Fewer forcing lines mean more decisions, and every decision is a chance to err. Where pieces show you the path, even a memoriser survives; where you must find the plan, the clock runs out. The DVD does not mention this risk once.
And there is an internal tension. The argument is that 9...Nh5 is forcing and computer-relevant, therefore 9...a5 is preferable. But against a strong, engine-prepared White, entering a theoretically secondary line concedes the initiative without compensation. The variable being optimised is comfort, not expected score. Comfort is a legitimate purchase; it cannot be sold as the best preparation.
The question is not memory versus understanding; it is comfort versus expected result. The second is being advertised while the first is being sold.
This small DVD is a miniature of a larger problem in my own city. Why does a club player in Dhaka buy such material? Because there is no coach. The coaching chain Bangladesh should have built never existed. The last home norm tournament was held in 2026; seventeen years on, the country still has five grandmasters and no sixth. The federation's annual budget is roughly Tk 11 lakh — less than a single franchise cricketer's bat deal. That is my one cricket comparison, and it concerns money and infrastructure, never sentiment.
On that budget there is no school-level coach education, no norm-tournament calendar, no regular funding to send juniors abroad. So players try to coach themselves, and the market sells them confidence.
Open the old notebook. When Niaz Murshed became a grandmaster in 2026, we thought a door had opened. In 2026 Viswanathan Anand became a grandmaster. India walked through that door and built a machine — schools, salaried coaches, a norm calendar, long-term sponsorship. We built a statue. A statue is venerated; a statue gives no junior a rating.
The crisis is not one of talent but of employment. Parents who steer a son towards engineering rather than chess are not betraying a culture; they are making a rational economic call, because chess does not pay the rent.
And that argument returns me to the DVD. In a society that does not demand verification from its institutions, the market does not demand it either. We put Capablanca on the cover because Capablanca is safe; nobody reads what is inside, because reading means asking. The same habit runs through a national budget and a personal purchase. Nobody publishes how Tk 11 lakh was spent, and nobody publishes who wrote the DVD. Two places, one deficit: the absence of a record.
My second memory applies here. In 2026 I stood before two crowds in one year. In June my city hosted the football World Cup — eleven cities, fan zones, eighty-thousand-seat stadiums. In September I flew to Batumi for the 43rd Chess Olympiad, where more than 180 federations gathered, China took both the open and women's titles, and the hall held almost no cameras. Two pitches, one year. The loud pitch needs no poet; the quiet one does. But quiet is not darkness — quiet means nobody is writing the testimony down.
And a sport that keeps no testimony makes both fraud and exaggeration easy.
In 2026 I commentated the FIDE Online Olympiad final from my kitchen in Saint Petersburg — India against Russia, ending not in checkmate but in a disconnection, both teams awarded joint gold, thousands of fans asking whether a result counts if nobody touched a board in the same room. That summer the Dhaka Premier Division League went dark and players with day jobs stopped receiving match fees. I spent July interviewing them about rent. Nobody wanted tactics; everybody wanted to be heard.
That changed my writing permanently. I stopped opening with results. I open with what the camera missed — a hand, a move, a cover.
The pitch remembers what the camera missed; so does the board.
So what is the objection here? Not to 9...a5. The move is sound, playable, reasonable for anyone comfortable in closed structures. The objection is to the advertising: a secondary line sold as an antidote, an author left unnamed, sample games withheld, and an outdated technical claim used to move new stock.
The second half of the objection is less comfortable: as readers, we want the gap. We want one simple sentence — play this and your problems end. The complex truth is that no move ends the problem; preparation habits do. The market gives us comfort because comfort sells.
The question I would put to every reader is plain: before buying this, what would you want to know? The author's name? A list of sample games? The engine version and depth? The database ratio for the structure? If those four answers are missing, you are not buying chess — you are buying confidence, and the price will be paid out of your rating.
Bangladesh's question sits on the same line. The sixth grandmaster will not arrive from a DVD, nor from the discovery of a new move. He will arrive from a coach's salary, a school circuit, and a norm-tournament calendar that has been closed since 2026. A fourteen-year-old national champion proves a pipeline is possible; he is not the pipeline. The question is not about him but about the coach standing beside him — who pays that salary, and who keeps that ledger.
The golden memory of Buenos Aires and the empty calendar in Dhaka are two faces of one account. One says what we achieved; the other says who paid for it. A Capablanca on the cover makes a buyer believe the history is inside the product. History reminds; it does not audit.
If you sit at the board tonight and choose 9...a5 as Black, know what you are buying: time, quiet, and a long strategic fight in a closed structure. You are not buying guaranteed equality, and you are not buying computer ignorance.
Two pitches, one year, and the quiet math — in the end the board is the witness that never stopped recording. The only question left is who reads the record.
