The ChessMom DVD and 9...a5: Auditing a Practical 'Antidote' to the King's Indian Bayonet Attack

There is an old DVD case in the corner of my desk in Khulna. Dust has settled on the sleeve, and when I run a finger across it the date surfaces: 2026. Inside, on a folded sheet, three characters are written in a quick hand — 9...a5. The steel cupboard still holds the echo of a crowd that never came. That case is where this piece begins, because a fresh promotional pitch now claims that in the King's Indian Defense, Mar del Plata Variation, the answer to White's Bayonet Attack is 9...a5 — the practical antidote that frees Black from the forced memorisation of the main line 9...Nh5. It is a handsome claim. But since 2026 my desk has followed one rule — every piece opens with a dated physical object — and that rule makes me ask for the account first: where is the evidence?

Context: know the board before the claim

The King's Indian — 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 — is a hypermodern defense. Black deliberately concedes the centre, then strikes back with ...e5. In the Classical branch, 7...Nc6 begins the Mar del Plata Variation, where the two sides attack on opposite wings: White on the kingside, Black on the queenside. That imbalance is what gives Black the courage to play for a win, and what forces White to decide whether to squeeze slowly or storm.

White's Bayonet Attack, 9.b4, is one of the most fashionable systems in the whole complex; it established itself on the international board in the 1990s. The logic is simple: the move restricts Black's queenside plans, creates the b5 and c5 thrusts, and keeps the e4-e5 build-up on the kingside in reserve. For decades the main answer has been 9...Nh5 — lifting the knight to h5, preparing ...f5, opening the position, and entering forced, tactical play. White goes for the king; Black trusts in hard calculation.

This is where the DVD's sales pitch sits. Along 9...Nh5 the engine's account rarely runs out; for a club player it is a mountain of memory. The DVD says: play 9...a5, and with this quiet queenside step either force White's b4-pawn to b5 and freeze the structure, or shut the wing with ...a4 and run the slow machine of ...b5, ...Nc7 and ...Rb8. Less database memory, more conceptual load.

Core analysis: what the antidote actually costs

The difference between the two moves is this — one forces you to calculate, the other forces you to understand. One is a game of tactics, the other a game of plans. In practical terms the appeal of 9...a5 is real: less memorisation, more themes, and comfort in fast time controls.

And yet the question stands. The DVD's pitch says that computers often do not know how to handle the arising complex strategic positions. In the engine era that sentence is dated. Modern engines read the closed, slow King's Indian positions very well; it is humans who err more in such positions. So this is not a technical claim but a marketing ornament — and it is the ornament the line is sold on.

The larger gap is numeric. The DVD's central claim — that objectively chances are equal, yet things quickly become dangerous for White once Black knows the plans — is supported by no engine evaluation, no ACPL, no sample games and no database statistics. That is not surprising; it is the norm for this kind of product. Still, it is the single most important fact for a buyer: you are purchasing a promising plan, not a proven equality.

Closing that evidentiary gap is not hard. The 9...a5 idea is nothing new — it is a known sideline that fights for space with ...a4 and ...b5 while dodging the forcing ...Nh5 branch. You can check the line in the ChessBase or TWIC game archives, and run it through a current engine to see whether its score really is worse than the main line. Two tasks, one hour. What the DVD withheld, the buyer can supply.

There is a simple practical test I teach juniors. Take the sideline into twenty fast online games, then walk back to moves fifteen to twenty with an engine, mark where you lost time, and note which plan tripped you up — ...b5 or ...a4. The one that sits easily in your head is your repertoire; the one that looks pretty in a database belongs to someone else.

My desk experience teaches one rule here. In 2026, at the federation hall in Purana Paltan, I sat for four days and found Niaz Murshed's 2026 norm sheet in a steel cupboard, a coffee ring dried across the black queen's square. That 4,000-word piece became the site's most-read story. And the top comment, from a twenty-nine-year-old reader, was three words: Who is Niaz? That day I understood that proof of talent often sits in a cupboard while nobody keeps its account. In the opening market the opposite happens: the evidence is never in the cupboard, the market chases the claim.

DVD versus subscription: the economics of distribution

The DVD is now a legacy channel. Chessable, Chess.com courses and subscription streaming have taken its place. Demand is met, but it depends on market-friendly language; the word antidote is itself a sales device. Nobody would buy that 2026 case today, yet its claim has returned in new packaging — that is the cycle of the opening market. The repertoire industry runs its own arms race: more sidelines, more courses, more words. What the buyer actually needs is a reliability filter that separates signal from noise.

Some platforms are now experimenting with blockchain-based licensing and course ownership as the next step in digital distribution. The reliable data on this is still thin, so no firm conclusion can be drawn. The question, though, is fair: if it were written on a ledger who earns from a course, perhaps the question of who is Niaz would not have come back. Technology does not fix a talent shortage; it can fix the transparency of the account.

Contrarian angle: the real antidote is not a move

Everyone assumes the antidote is a move. My ledger says the antidote is the economy of preparation. The practical edge of 9...a5 is really an information asymmetry. While the line stays rare on club boards, Black plays in comfort. Once it is popularised, White prepares afresh and the edge dissolves. The promise of less memory, more understanding is also a kind of load-management romance: it sounds comfortable, and it does not change the reckoning on the board.

The Bangladeshi context adds a further layer. No new grandmaster has emerged here since 2026; the federation's annual grant is small, the Standard Chartered school pipeline has collapsed, and no home norm tournament was staged through the 2010s. In a country that cannot even host a home norm event, the 9...a5 versus 9...Nh5 argument sounds like a luxury. In 2026 Ziaur Rahman died at the board; standing beside that fact, writing about the beauty of a sideline is easy, but the account is uncomfortable. The fault lies not with parents or with teenagers grinding moves online at night; it lies with an economy that never turned chess into a job.

And still the game survives indoors. In March 2026, from my Khulna flat, on a router that dropped every forty minutes, I covered Leonine Chess Club's online rapid: 128 players, no arbiter, no handshake, and a nine-year-old beating an IM in 31 moves. The summer stayed home, so the game learned to whisper through screens. In 2026, while Tokyo staged an Olympics in empty stadiums, Bangladesh's team played from bedrooms — Rani Hamid, at seventy-seven, still winning games for the women's side. In December 2026, in a Dhaka junior hall, I watched twelve-year-old Manon Reja Neer refuse a draw in a 78-move rook endgame and play on for two more hours; he lost, and I stayed until the lights went off. Some draws are not stalemates; they are vows the boy kept to himself.

Final account

Forty squares, no crowd: the board remembers what the terraces forgot. 9...a5 is a respectable practical weapon, but it is no antidote pill, and the DVD's claim of equal chances is the language of the market, not the result of a test.

The real question is not technical but financial. The country that produced South Asia's first grandmaster in 2026, a year before Anand, yet has not grown another since 2026 — when it argues about the next 9...a5, who gains? A DVD case may gather dust, and we write poems out of that dust. But the coffee ring on our own board has not dried yet; who will keep its account?
