Why 9...a5 Is No Longer an Antidote in the Engine Era: The Bayonet Attack, a Samarkand Headline, and the Ledger of a DVD

No Move Is Written on an Empty Chair

It was 2:40 a.m. in Penang when a headline surfaced on my laptop screen — Samarkand, round seven, open section, Uzbekistan continuing their dominant run and extending the lead. Anyone awake at that hour would sit down with a cup of tea. I sat down. Then I opened the link and found no scores, no standings, no boards, no player names. What I found was a DVD advertisement: a new antidote to the Bayonet Attack in the King's Indian Defence, a move called 9...a5.

I stared at the screen for a while. The whistle blew, and my knee learned a language no box score could translate. That was 2026, when I was a sixteen-year-old winger and that language pushed me to the sideline. Watching from there, the game slowly became a sentence I could finally edit. At dawn, that old habit kicked in: I read the headline, then walked down into the sentence — and the sentence no longer matched the headline.

My notebook is called "Things the Scoreboard Cannot See." Since 2026 I have collected moments nobody records before results arrive. Today's is different: there is no result, but there is a ledger. In chess, a ledger is not only a rating; it is also who pays, who gets a board, and who writes the headline.

No move is written on an empty chair. That was my first lesson, learned in a tea stall in Purana Paltan from a Dhaka chess secretary. An empty chair stops the clock, and a stopped clock makes no story. But in the 2026 chess internet, a story is manufactured even with empty chairs — headline, tags, clicks. Today's discussion stands between those two worlds.

Context: Mar del Plata, the Bayonet, and Two Hands

The King's Indian Defence is chess's strangest defence. Black does not begin with a knight but with a pawn, then fianchettoes the king's bishop, then strikes at the centre with...e5. If White castles long and Black castles short, both sides declare war on opposite wings — that is the Classical, that is Mar del Plata.

Black enters Mar del Plata with 7...Nc6. When White castles short and then plays 9.b4, that move is the Bayonet Attack. The name is elegant, and so is the work: b4 clamps down on c5, and b5 drives the black knight off c6, freezing Black's queenside. White is saying: you may storm my king, but first I will brick up the back door of your house.

Black usually has two major roads here. The first is 9...Nh5. The knight goes to f4, becomes a shield in front of the king, then...f5 and...f4 launch the storm. This road is powerful but forced — many moves are near-inevitable, and both players arrive having memorised them.

The second is 9...a5. Quieter, but real. Black touches the Bayonet directly: by conceding a pawn weakening on the a-file, Black destabilises White's b4 pawn, shapes the structure, and pushes the game from piece-by-piece calculation toward spatial bargaining. The DVD markets this second road with the word "antidote."

I laid out the DVD's claims. Claim one: 9...a5 produces complex strategic positions with few concrete lines. Claim two: computers often cannot handle such positions. Claim three: objectively, chances are equal. Claim four: if Black knows what to do, things can quickly become dangerous for White.

Meanwhile the headline spoke of another world: Samarkand, Uzbekistan, open section, round seven. Uzbekistan's rise is real. They won gold in the open section of the 2026 Chennai Olympiad. Nodirbek Abdusattorov became world rapid champion in 2026 at seventeen. Javokhir Sindarov, Nodirbek Yakubboev, Jakhongir Vakhidov — a deep cohort. Samarkand's international opens are part of that growing infrastructure.

But no bridge connects the two worlds. The DVD text contains no Samarkand, no Uzbek name, no standing. The distance between headline and body is today's biggest fact. Before discussing that distance, though, we must return to the board — because without verifying the board, any explanation of the gap stays hollow.

What Actually Happens on the Board

To understand the Bayonet, understand what White wants. Black's centre rests on the e5 pawn, backed by d6. If White can pressure d6, Black's whole flank freezes. Occupying c5 means Black can never break with...c5 — the defence's main job is disabled.

The b4-b5 push then drives the knight off c6. With the knight gone, support for e5 drops, and Black is pressured toward...e4. Black often storms the kingside in the King's Indian, but that storm required a stable centre. With b5, White breaks that condition.

I remember December 2026, the Premier Division Chess League in Dhaka. In a chess world whose annual government grant is roughly 1.1 million taka, Indian grandmasters are hired as guest boards by Police, Navy, Biman and the bank teams. In a tea stall in Purana Paltan an arbiter told me: there is no shortage of talent here, only a shortage of tables. In the King's Indian, Black's problem is the same — the right piece is not on the right square.

9...Nh5: The War of Memorisation

After 9...Nh5, the game turns violent fast. The knight shields the king on f4,...f5 advances the kingside pawns,...f4 shuts the door. White opens the b-file, and grandmasters often burn Black's queenside with a4-a5. Both sides swing knives on opposite wings, and whoever errs first loses.

The problem is real: the best lines are enormous, the first twenty-five to thirty-five moves are near-forced, and engines have refined them so precisely that nobody wants to gamble from memory. For a club player, thirty memorised moves against an opponent's eighteen is less chess than an examination.

That memorisation fatigue — not any theoretical gap — is the true market for antidotes to the Bayonet Attack.

9...a5: Structure Over Space

After 9...a5, Black says: I will stand beside your b4 pawn and make it unstable. If White captures on a5, the game opens; if White avoids it, Black may half-open the a-file and tie down White's queenside pieces. In both cases one thing changes: White's favourite b4-b5 lever no longer works as before.

Structurally Black gains something irritatingly valuable: pressure on the a-file, new ways to break with...c5, freedom to reroute the c6 knight, and time to arrange pieces around the king. Violence decreases, but Black does not die — Black nests inside the position.

Here is the first problem. The word "antidote" sounds clinical, but 9...a5 proves nothing as forcefully as the main line 9...Nh5. It is a known sideline that survives as a practical choice. Calling it new is wrong; calling it main is wrong. The DVD sells reconsideration, not discovery.

An opening product is judged not by its force but by its honesty: what does it claim, and what is the evidence?

"Computers Cannot Handle It" Belongs Before 2026

Here is the biggest technical problem. One claim says computers often cannot handle such complex strategic positions. That sentence is a familiar story from chess's pre-engine era, and its shelf life has expired.

AlphaZero showed in 2026 that positional understanding and merciless calculation are not separate things. After NNUE arrived in 2026, engines like Stockfish and Leela became far more reliable in closed structures, cramped pawn chains and long plans. The engine on a taxi driver's phone can now evaluate the positions arising after 9...a5 perfectly well.

This does not mean 9...a5 is bad. It means the road's value lies in human memory, not engine blindness. In a club tournament where White knows the vast 9...Nh5 lines better, Black may survive by choosing 9...a5. That is memory management, not computer failure.

In the modern engine era, a product's weakest point is its ancient marketing language — when you read "engines won't understand this," ask when that sentence was written.

"Chances Are Equal" Is a Claim, Not a Verdict

Another sentence says chances are objectively equal. Objectivity is a big word, and big words need numbers beside them: a current engine evaluation, a defined database sample with results by level, and an accuracy metric. The DVD description contains none of these — no evaluation, no game sample, no average centipawn loss, not even an author's name.

The industry arithmetic is simple and cruel: equal chances is a verifiable claim, and a verifiable claim without evidence becomes advertising copy. In my own column I hold one rule — every emotional piece must contain at least one number that embarrasses an administrator. The same applies here.

In the antidote market, the rarest commodity is evidence and the easiest is promise.

Who the DVD Is Actually For

A product is easiest to identify by imagining its buyer. At elite level, 9...a5's answers are already verified in preparation files, because top players have analysts and engines at hand. There, the appeal of avoiding lines is weak.

The real buyer is the club player and IM-level player — someone who plays twice a week and wants to skip opening trouble. The market thesis is honest: modern preparation really has become excessive memorisation, and a calmer strategic path genuinely appeals. But if the marketing argument is false, the error spreads through coaching. A junior who reads "computers do not understand this position" may stop using engines — and lose far more.

Where There Is No Inventory: Bangladesh's Ledger

South Asia's first grandmaster was Bangladeshi. Niaz Murshed became a GM in 2026; Viswanathan Anand became one in 2026, a year later. Since then India has produced more than eighty grandmasters, while Bangladesh still counts five. Since 2026, no new Bangladeshi grandmaster — a seventeen-year drought.

In 2026, Ziaur Rahman — a fifteen-time national champion and one of the country's finest players — died of a heart attack during a game on 5 July. I had emailed him four times for an interview since 2026; the fifth email was a condolence note. In December that year, fourteen-year-old Manon Reja Neer won the National Championship undefeated. I wrote both stories as one, because they are one.

And the ledger? The Bangladesh Chess Federation's annual government grant is roughly 1.1 million taka — less than a single franchise cricketer's bat sponsorship. In 2026 the school chess programme was shut down, and no domestic path replaced it for the post-Niaz generation. Parents rationally steer children toward engineering.

Where there is no money for boards, an opening-theory DVD is a luxury — the scarcity is not theory, it is tables.

The Contrarian Angle: What the Headline Conceals

Back to that screen at dawn. A genuine Samarkand round-seven report would be valuable: who is playing, on how many points, the pairings, where the clock stopped. Instead the headline fuels a product page.

The mechanism is now almost a rule in small chess media. Uzbekistan is a trending name — 2026 Olympiad gold, Abdusattorov's rapid title — so putting Uzbekistan in a headline brings search traffic. Producing the news itself is unnecessary when the click leads to a sales page. I fear this because I have been guilty of it: my worst professional errors came not from bad writing but from the temptation of attractive headlines. Since then I have held a rule: I do not write a headline for a result I cannot verify.

The real crisis here is bigger than chess theory: the smaller the sport, the shorter the news chain, and the shorter the chain, the fewer verification steps.

Second Contrarian Claim: The Strategy-Versus-Calculation Split Is a Myth

Behind today's claims sits a deeper idea: calculation belongs to engines, strategy belongs to humans. That split no longer exists. A strong player measures rhythm, pawn risk, time pressure and opponent comfort at once. Engines have moved the same way. Before NNUE, engine strategic blindness was real — and that is exactly when the sentence "computers cannot understand this" was written. It now sounds like an old record that no longer plays.

The practical consequence matters. A club player who believes engines cannot handle closed positions may skip analysis and stop reviewing games — and exactly there progress stalls. My own biggest improvement came when I dropped the superstition and began questioning engines.

Any training method that fears the engine discards the sharpest learning tool available.

What 9...a5 Is Genuinely Good For

Honest assessment: 9...a5 is not the main line, but it is not bad. It is a practical decision, admirable in specific settings — when Black wants to play quickly and avoid deep theory; when Black knows White is a memory player; when the event is a small open where opponents decide fast. Conversely, against an engine-backed preparation file, Black must show that calm play is not enough — the exact reaction sequence must be known. Time control is decisive: a "strategic" position under fast time is not a safe position. The clock runs even in quiet rooms, and the board does not forgive mistakes.

The DVD says one honest thing: "few concrete lines on this path." The subtlety is different — fewer concrete lines gives Black more freedom, but also gives White more freedom. Where theory has no walls, a strong opponent gets room to build plans.

How to Read a Product Like This

• Check a current engine evaluation after White's main replies.
• Search a game database for 9...a5 games, results by level, and years played.
• Find the author's name and title, and verify their King's Indian credentials.
• Look for an evaluation beside "chances are equal"; if absent, treat it as a claim.
• Practically: if your preparation time is short, this path may suit you; if you are a memory player, argue with the engine before the board.

One Plausible Explanation, and Why It Matters

There are two plausible causes of the mismatch. First, a genuine extraction error: a headline attached to the wrong body. Second, SEO bait: a headline borrowing a live event's name while the body sells a product. I cannot determine which is true alone — and that is the point. If a Samarkand round seven genuinely happened, its result deserves reporting by someone who finds the standings rather than copies the headline.

Since 2026 I have followed a strict rule: after Ziaur Rahman's death, I do not file hasty pieces that could wound a family. The same rule applies here — when part of the information is doubtful, no large claim can rest on it.

Takeaway: The Clock Will Stop One Day

The community most at risk here is not the DVD's buyer but Bangladeshi chess. A country whose first grandmaster preceded India's, whose federation grant is 1.1 million taka, whose Premier League rents foreign grandmasters instead of building its own generation, faces an infrastructure question rather than a theory question.

Uzbekistan offers the reverse lesson: a deep cohort, state and institutional support, home opens, and Chennai Olympiad gold. That road began twenty years ago; results are arriving now. Chess develops through budgets, coaches and tournaments — not advertising sentences.

I am not anti-technology. A player who buys the DVD and starts playing 9...a5 may enjoy calmer games and learn something memory chess cannot teach. But I want that player to ask one question before leaving the room: who wrote this sentence, when, and how much of it can be verified?

From the last page of my notebook: what the scoreboard cannot see is that first moment a hand touches the board and the fingers tremble. No DVD, headline, link or traffic explains that tremble. The biggest question in the 2026 chess world therefore remains unexplored: will we learn to love the game again, or only to sell it?
