9...a5 and a Promise Without Numbers: When an Opening DVD Sells a Sense of Safety to King's Indian Players

I opened the analysis file at 2 a.m., the desk lamp shining on two pages, and the first thing I saw was not a move but a mismatch. The original article's headline described a team-event round in Samarkand — "R2 (open): Despite close calls, all top teams grab wins" — while the entire body below discussed a chess DVD teaching 9...a5 against the Bayonet Attack. Two unrelated texts bundled together. No team, no game, no score mentioned in the body. Only an opening product being marketed.

Misreading a player's name is not terrifying. Misreading a game is a catastrophe. And here, from the very first line, the editor had misread the game. That forced me to do what I have done for twenty years: strip the packaging, find the real skeleton, and ask a simple question — what is this product actually selling?

The short answer: it sells a sense of safety. The longer answer is the story of this article.

Context: Mar del Plata, Bayonet, and the two doors of the Black side

To understand why a move like 9...a5 needs its own DVD, it must be placed in the right spot within modern chess theory.

The King's Indian Defense — KID — begins with 1.d4 Nf6 2.c4 g6, with Black placing the bishop on g7 and conceding the centre in the early phase. This is hypermodernism in its classic form: do not occupy the centre with pawns, let the opponent take it, then attack that centre. The Mar del Plata variation is the sharpest branch of the KID, where Black develops the knight to c6 and pushes e5, creating mutual wing attacks — White on the queenside, Black on the kingside. Its ECO codes fall roughly between E97 and E99.

For decades, Mar del Plata was the weapon of players who loved violence on the board. Then came the Bayonet Attack. White's 9.b4 — bayonet, the blade fixed to a rifle — thrusts the b-pawn forward to seize queenside space, threatening b5 and preparing a mass pawn advance on that wing. This is the fashionable answer top grandmasters have used to trouble Black for more than two decades.

Black's main answer to the Bayonet is 9...Nh5. I call it "the sharp door." The knight jumps to h5, threatens f4, forces White to calculate concretely. After 9...Nh5, the game opens, forcing lines appear, and computer analysis becomes central again. This path demands memory, precision, and tolerance for calculation pressure.

The second door is 9...a5. The a-pawn strikes directly at White's b4 structure, not threatening the kingside directly, but pulling the game into a long strategic struggle. Black does not try to seize an advantage through a concrete blow, but seeks to flatten the position, keep a solid structure, and let White create problems alone.

The DVD advertised in the original article sits behind the second door. And that is the starting point for my entire story today.

What the DVD really sells: a promise of freedom

I read through every information point in the original package. Not a single concrete game. Not a single engine evaluation. No ACPL, no win rate, no database figures. Only sentences like "9...a5 leads to sound positions with very few concrete lines," and "if Black knows what to do, things quickly become dangerous for White."

That is marketing language. And it targets a very specific market segment: amateur players, from club level to international master, who lack the time to memorise hundreds of forcing variations, yet still want a credible weapon in their pocket. The players the advertisement describes as "those who prefer to think for themselves rather than memorise."

I have spent enough time in press rooms to recognise this pattern. When an opening product cannot boast a novelty, it boasts strategic character. When it cannot prove an objective edge with an engine, it shifts to promising a psychological edge. When it has no data, it has a feeling.

And here is the subtlest point the ordinary reader misses. The DVD's core promise is not "9...a5 is stronger than 9...Nh5." It is "9...a5 is more bearable than 9...Nh5." These two sentences are very different. The first is a theoretical claim requiring evidence. The second is a claim about user experience, and by nature cannot be falsified with data.

That is why this package is both attractive and suspicious at once. It is attractive because it touches a real pain: most KID players do not lose for lack of talent, but from exhaustion memorising 9...Nh5 variations. It is suspicious because it converts that pain into a reason not to need technical verification.

Core analysis: the three layers of an opening product

From years of following KID games at grandmaster level, I learned to peel an opening product into three separate layers. The first layer is technical truth. The second is the marketing frame. The third is the gap between the first two. This DVD is no exception.

Layer one: technical truth

The first and most important truth: 9...a5 is not a novelty. It is recorded in theoretical systems, played at high level, and is a secondary branch of Mar del Plata. No claim in the package says it is a novelty. That is a small honesty bonus.

The second truth: the Bayonet Attack 9.b4 is a highly fashionable branch, and White players at grandmaster level prepare thoroughly. Any "antidote" to a popular line will be tested, analysed, and countered. The cycle of modern chess theory is short. A move can be a surprise for one season and become ordinary the next.

The third truth: the claim that "computers often do not know how to handle these complex strategic positions" is a trace of a bygone era. I have followed engines from Stockfish 8 to modern neural networks. Before AlphaZero, that sentence had merit. After AlphaZero, engines handle the long-term strategic positions of the KID far better than the advertisement implies. This is dated marketing language, and it is a small red flag any buyer should notice.

Layer two: the marketing frame

The marketing frame has three clear pillars.

Pillar one: an artificial opposition between "human" and "computer." The advertisement casts 9...Nh5 as the symbol of the engine era — open position, forcing lines, making computer analysis important again. And casts 9...a5 as the symbol of the human era — strategic, low-memorisation, freedom of thought. This is an emotionally attractive opposition, but technically false. Both moves can be analysed with an engine. Both can be memorised. The difference lies in the degree of forcing character, not in whether a computer is involved.

Pillar two: the promise of "very few concrete lines." This is the most attractive promise for amateur players, and also the hardest to verify. Mar del Plata is by nature a sharp system. Even when Black chooses the more strategic path, White can still force the game into lines involving concrete calculation. No branch of the KID removes the need for calculation entirely.

Pillar three: the promise of "quick danger for White." This is absolutist, and depends entirely on White's level of preparation. If White is well prepared, the sentence may be true. If White is unprepared, the sentence is true but meaningless. The claim cannot be verified from the original text.

Layer three: the gap between the two layers

The largest gap is the author's absence. No name. No title. No KID track record. No sample games. No engine evaluations. In a market where author credibility is the most important asset, this absence is a major gap.

I once told a young editor that you do not need to be a grandmaster to write about chess. You need to be someone who can prove you know what you are talking about. This product cannot do that. It sells a move, a philosophy, and a feeling of freedom — but it does not sell evidence.

Contrarian angle: why "antidote" is dangerous selling

I mispronounced a player's name, then read the position correctly when the slow-motion replay appeared before my eyes. There is a pattern in the chess-theory publishing industry I have observed for two decades. The pattern is: no move is an antidote to anything. There are only moves that require both sides to work.

When a publisher sells an "antidote," buyers typically do two things. First, they underestimate the preparation needed to understand where the antidote actually works. Second, they overestimate that the opponent will be unable to respond. Both are psychological traps.

Take an example from my experience as a tournament organiser. At an open in Delhi, I watched a young player adopt an "antidote" move advertised as unstoppable. He memorised the main variation, played it in the first two rounds, and won confidently. In round three he met an older opponent who played a simple sidestep the material never mentioned. The young player lost his bearings, made meaningless moves, and lost in 25 moves. The move was not wrong. Misunderstanding its value was wrong.

This is why I always distrust opening products using the word "antidote." Not because they are useless. Because they promise a safety that does not exist. Safety comes only from deep understanding, not from memorising more.

Interestingly, there is a hidden paradox in this advertisement. If the DVD truly teaches players to "think for themselves," it cannot teach through a set of memorised variations. And if it teaches through a set of memorised variations, it betrays its initial promise. This product escapes the paradox by talking about "philosophy" rather than "variations." About "structure" rather than "moves." About "feeling" rather than "numbers." This is a clever marketing strategy, and a weak knowledge-transfer strategy.

The strong players I know do not learn by trusting a product. They learn by placing the product on the table, evaluating each claim, and testing it against their own database. That process cannot be packaged into a DVD.

The bigger problem: headline and body do not match

I must return to the problem I raised at the start. The original headline discusses a team-event round in Samarkand — "R2 (open)," "all top teams grab wins." The body discusses an opening DVD. Two different topics. No intersection.

This is not a small detail. In the sports journalism I work in, this is a serious credibility failure. When a content package has a headline and body that do not match, the intelligent reader should re-ask the question about the source. Not because the content is certainly wrong, but because careless splicing shows weak editorial control.

In fact, two scenarios could explain the mismatch. Scenario one: a real report on a team event in Samarkand exists, and was mis-paired with a DVD advertisement during aggregation. Scenario two: a technical failure in the editorial system placed both texts in the wrong spot.

Whatever the scenario, the consequence is the same: anyone citing this package without verifying the original source may be transmitting false information. I have seen young journalists make this mistake. They take an analysis package, trust the headline, and publish without verifying. That is a fast way to lose credibility.

Samarkand — to my knowledge — is an active chess city in Uzbekistan, and team events in that region are not rare. If a real report of a round there exists, it needs to be analysed from its own primary source, not from this one. If no real report exists, the entire package is an aggregation error, and its reference value is close to zero.

Buyer risk: five things to consider

When I evaluate an opening product, I always look at five categories of risk. This product faces all five.

Theoretical risk

9...a5 is a familiar branch. White players at high level know it. They can prepare a response. A move has surprise value only when it is genuinely surprising. Once public, that value drops.

Buyer-expectation risk

A buyer may pay for a DVD advertised as "no memorisation," only to discover that playing KID Mar del Plata still demands deep preparation. This disappointment is the direct result of the gap between marketing and reality.

Financial risk

Such a DVD competes directly with free databases and free engine tools. Its content — variations, strategic ideas — is available in many places for free. The real added value must come from editorial structure and author credibility. Neither is proven in this package.

Psychological risk

The advertisement builds an image of a player who "thinks for himself." This is one of the most effective sales methods in chess. But it can also create overconfidence. Players believe they have grasped the "philosophy" when in fact they have only memorised a few main variations. That gap will be exposed in real games.

Systemic risk

The claim "computers do not understand" reinforces an outdated anti-engine attitude. In modern chess, using engines is a core skill, not a sign of weakness. A product encouraging players to turn away from engines harms them, however unintentionally.

The wider market picture: KID in the engine era

To place this story in context, one must look at the position of KID in general and Mar del Plata in particular in modern top chess.

The truth is that KID has lost market share in classical grandmaster events. Systems like Grünfeld, Nimzo-Indian, and the Italian Game dominate most top-level games because they carry less theoretical risk. KID survives, but more as a "surprise weapon" than a main choice. A grandmaster choosing KID usually does so because they trust their attacking ability, or because they want to avoid familiar lines of mainstream systems.

Mar del Plata is the first KID branch to work at top level in the engine era. It still works, but with reduced frequency. The Bayonet Attack 9.b4 is one of the main reasons White chooses the system — it is a tool to trouble Black. Any product promising to "solve" the Bayonet competes in a very narrow, very specialised market, and is very hard to sell with a document lacking numbers.

It is fascinating to observe a larger trend. While opening products try to sell "lightness," the reality of top chess moves the other way. Grandmasters prepare more, not less. They use more engines, not fewer. They remember more variations, not fewer. A product selling "lightness" can succeed in the amateur segment, but it does not change the reality of top level.

Three verifiable predictions

Prediction one: if 9...a5 genuinely appears in a classical 2700+ event, I will reassess my entire view of its value. How to verify: monitor top-level games databases over the next 12 months.

Prediction two: if it does not appear at top level, attention to the DVD will decay within one theory cycle — a few months. How to verify: monitor discussion on specialised chess-theory forums.

Prediction three: any short-term attention will provoke a White-side response — a new line or refreshed idea for the Bayonet. How to verify: monitor new Bayonet theory publications over the next 6 months.

What readers should remember when leaving this article

I am 60. I have spent over 40 years observing the chess industry from many positions: organiser, commentator, writer. In that time I have seen many opening products come and go. Some left a mark. Most did not.

What I have learned is this: the value of a chess product lies not in its promise, but in its ability to survive independent testing. A good product does not fear engine verification. A good product does not fear revealing its author. A good product does not need the phrase "computers do not understand" to convince you.

If 9...a5 is a genuinely valuable strategic idea, it will survive without a thick marketing layer. It will appear in top games. It will be analysed by leading players. It will prove itself.

If it does not exist that way, then the buyer paid for a feeling, not a fact. And that — not the move, not the DVD, not the headline — is the real story this article should have told from the start.

In chess, as in journalism, there are no antidotes. Only work and verification. That is the only promise I will offer anyone asking what to buy to play the KID.

The question I ask does not sound like a woman's, but the answers they dodge do not sound like a man's. And after twenty years standing in arguments like this, I still believe a right question is worth more than a good DVD.

The empty stadium that year — I found the tactical diagram lying still under the seat rather than the roar. This package is the same. No spectators. No games. Only a diagram trying to convince me it is the truth.

I am not convinced. But I will keep watching. That is my job.
