Named 'Mother', King's Indian Inside: The ChessMom DVD, 9...a5, and the Arithmetic of Marketing

The DVD menu shows a picture — a mother, a boy seated beside her, a chessboard spread out in front. Above them the words: "ChessMom returns: Supporting mothers on and off the board." Before pressing play, you assume this is an emotional course about a parent and child, a message of encouragement. What actually opens is not that story. It is a King's Indian Defence repertoire — a prepared opening plan for Black — and at its centre a single recommendation: Black's ninth move, 9...a5, against White's Bayonet Attack (9.b4).

The picture is one place; the move is another entirely. That gap is what tells me the most. In the print era of the late eighties, when I first wrote moves with a Dhaka sports page in hand, I learned the same lesson — a headline and a board position rarely say the same thing. The pitch remembers what the camera missed. Here too. The name says 'mother'; inside plays the King's Indian. And within that gap lies the DVD's real story — its claim, its weakness, and the cold arithmetic of the opening-theory market.

The board the camera never reaches

To understand this, you first have to know the board. The King's Indian Defence — 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 — is a hypermodern defence. Black deliberately concedes the centre to White, then strikes with ...e5. In its Classical branch, the so-called Mar del Plata Variation, Black develops the knight to c6 on move seven (7...Nc6). Both sides then attack on opposite wings — White toward the king, Black toward the queen. It is one of the bloodiest, most complex opening schemes in chess history: a race over which attack arrives first.

This is where the Bayonet Attack arrives, 9.b4. White's pawn move wants to block Black's queenside plans, claim space, and unsettle Black's knight. Black then has essentially two roads. One is the main line — 9...Nh5, where the knight rises to h5, the position opens, exchanges begin, and play turns sharply tactical and forced. In the engine era this line is analysed so heavily that it is called a war of memory — whoever remembers more lines stands ahead. The other is a sideline — 9...a5, the one this DVD recommends.

One thing needs saying plainly. The board's arithmetic and the camera's arithmetic are never the same. From years of watching matches I have learned that an opening's popularity is not measured by its strength but by its publicity. Covering the 2026 Tbilisi World Cup — a 128-player knockout across 25 days — I understood that viewers never see the objectively best move; they see the move whose story is told best. The same is happening with this DVD.

9...a5: a move of understanding, not memory

The idea behind 9...a5 is simple in intent, complex in result. It is not a new discovery — it is a known sideline in King's Indian theory, where Black seeks space on the queenside, plays for ...a4 or ...b5, and above all avoids the sharp, forced ...Nh5 lines of the Bayonet.

The DVD's core proposition is a practical sideline that reduces the burden of memorisation and pushes the player toward understanding. That is the product's real selling point. In the main line Black must memorise thousands of lines, in every tiebreak, at every fast time control. In the sideline Black instead holds a plan — gradual queenside pressure, a blocked centre, counterplay built before White's kingside attack lands.

Two different skills are at stake. The main line 9...Nh5 demands memory and calculation — keeping pace with the engine. The sideline 9...a5 demands understanding and patience — the ability to smell a position. The DVD targets the club-level player who is losing ground in the main line daily, because his opponent is preparing ten hours in front of a laptop while he prepares fifteen minutes.

And here is the first crack. The DVD claims that "objectively the chances are equal," and that if Black knows the plans "things might quickly become dangerous for White." A fine sentence, but there is nothing behind it. No engine evaluation, no sample games, no database statistics, no ACPL — the average loss per move against the engine's best. Only language, only promise.

I step back and reconcile the arithmetic. The Bayonet Attack is a fashionable weapon for White, and White plays it because he knows Black's most prepared reply is also the most tested against him. If Black plays 9...a5, White often does not know what to do — that is the sideline's true weapon, surprise value. But surprise value is used once, then gone. Once the sideline is popularised, White's preparation arrives too, and its weaknesses surface.

One more point deserves attention. The DVD says that "computers often do not know how to handle the arising complex strategic positions." In the engine era that claim is anachronistic, almost wrong. Modern engines handle the King's Indian's closed, strategic positions perfectly well — sometimes better than humans. It is not a technical claim; it is marketing language, the same language that has dressed weak products as strong for decades.

Still, the sideline has real practical value that cannot be denied. For a club-level player it is a working weapon. Black takes queenside space, keeps the position closed, blunts White's direct attack, and steers the game toward a setting where long-term planning matters more than memorised lines. It is the repertoire of the think-for-yourself player — one who likes plans, not forced lines.

To reconcile the board's arithmetic we must see two pitches at once — the one the camera shows and the one it does not. Two pitches, one year, and the quiet arithmetic — who stayed, who left. In 2026 I saw two crowds in one year — the football World Cup in June, vast stadiums and fan zones; and in September the 43rd Chess Olympiad in Batumi, more than 180 federations and almost no cameras. The loud pitch needs no poet; the quiet one does. This DVD is the market of that quiet pitch — small, devoted, nearly invisible.

The gap between name and record

Now to the place where the story turns uncomfortable. The title says 'mother', 'support', 'on and off the board'. Inside is a King's Indian DVD. The mismatch is not accidental — it is a warning. When a product's name and its content walk separate roads, it usually means the title is old, perhaps a series memory, and the content is far less attractive. Some will call it branding; I call it a packaging problem that strikes directly at the buyer's trust.

The second problem — no sourcing. Every claim here comes from a promotional text that nowhere states who is speaking, what the evidence is, or how many games were analysed. Yet the claim carries weight — calling a sideline "equal" means building a dependable wall for Black against a fashionable White weapon. Such a claim requires engine output and data from hundreds of games, not language.

Third, the text itself concedes that this is a practical alternative to the main line. That means, plainly, that elite players still play 9...Nh5 or its modern cousin 9...Ne8. The sideline is not an elite upgrade; it is a sideline. This is not weakness — it is honesty. But promotion takes a sideline, labels it an "antidote", and sells it as though it were better than the main line.

Finally, the structural question. A DVD is a legacy distribution channel, gradually being replaced by subscription courses and streaming platforms. In the chess market it is the same story — the person producing the preparation may be fine, but the system that sustains them is eroding.

Closing

This DVD will not change the structure of chess, win a tournament, or make history. But it raises a question we should keep asking: what are we actually buying — a move, or a story? The board is the only witness whose record never stopped.

Three things deserve watching. One, whether the engine rates 9...a5 as equal to the main line. Two, whether anyone at elite level starts playing it regularly against the Bayonet. Three, whether a White counter-preparation emerges that shortens the sideline's life. The answers will decide whether that DVD named 'ChessMom' was a working weapon, or merely the mask of a pleasant name.
