The 9...a5 Move, the Empty Applause, and a Mismatched Document

On an October afternoon in Nha Trang, I sat before my screen with a document a younger colleague had sent over. At the very top was a headline about round two of a tournament in Samarkand, where all the strong teams had won by narrow margins. The further I read, though, the more I realised I had wandered into an entirely different story. Beneath that title lay the promotional copy for a DVD teaching Black's ninth move in the King's Indian Defence. Two unrelated texts, spliced together like two chess games played on the same board with no one naming the opponent. Across thirty-two years of commentary for VTC, I have learned one thing: when the pieces do not fit, the storyteller must take them apart by hand and examine each one. The stadium is empty, yet the applause of 2026 still echoes inside every old record. And in this document, that applause rings out from a room far removed from the one the headline describes. So where does the core lie? It lies in Black's ninth move, and in a debate that has run for decades across the chess world. Twenty years ago I sat in a Saigon café with an old coach. He taught me to turn the pages of an opening book slowly, without hurrying. He said: "The King's Indian is not an opening; it is a declaration." The King's Indian Defence, or KID, begins with moves such as 1.d4 Nf6, 2.c4 g6, 3.Nc3 Bg7. Black deliberately concedes the centre to White, then counterattacks by degrees. That is the hypermodern approach, where patience is placed ahead of force. The Mar del Plata variation is one of the sharpest branches of the KID. Black plays ...Nc6 and ...e5 while White pushes pawns on both wings. The two sides attack on opposite flanks, and whoever arrives first wins. The Bayonet Attack, the move 9.b4, is White's way of seizing space on the queenside and forcing Black to answer. For years, 9...Nh5 was the mainstream reply. The knight leaps to h5, pressing White to choose, opening the position into a chain of forced calculations. That is why I am always wary of opening products advertised as an "antidote". The chess world is crowded with promises of that kind. This DVD, as described, proposes 9...a5 instead of 9...Nh5. The idea is plain. The pawn advances from a7 to a5, attacking White's b4-pawn and forcing an immediate decision. The move is not new. It has sat in databases for decades. What stands out is how the seller frames it. There is no claim of invention, only of practicality. According to the pitch, 9...Nh5 opens the position, forces concrete lines, and makes computer analysis important again. By contrast, 9...a5 leads to sound positions with very few concrete lines, suited to players who prefer to think for themselves. That is the appeal of the argument. I have watched hundreds of club-level games in which amateur players try to memorise long variations from opening books. They usually lose the moment an opponent steps outside the book. If there is a path toward a strategic position where calculation and positional feel matter more than memory, then that is a promise worth hearing out. But the promise carries a trap. I called three coaching friends in Hanoi, Da Nang and Can Tho. All three said the same thing: the Bayonet variation remains sharp, and 9...a5, though legitimate, is a side branch. No statistical table in the document proves that this move delivers genuine equality. There is no ACPL, no win rate, no sample game cited. Nor is the DVD's author named. We cannot tell whether he is a titled master with results in the KID. One other thing caught my attention. The document states that "computers often do not know how to handle these complex strategic positions." The sentence sounds familiar. It belongs to the era before AlphaZero, when classical engines genuinely struggled with positions demanding long-term thinking. In today's neural-network era, engines understand the KID far better than this line suggests. It is dated marketing language, and it reveals an obsolete mindset being recycled. There is a temptation I want to name. When an opening product promises "few concrete lines", the buyer often hears "no study required". But the Mar del Plata has never been flat ground. It has always been a place where calculation cannot be removed. The move 9...a5 redirects the game, but the new direction is still full of forks. A well-prepared White player can still find counterplay. The true value of this DVD most likely sits at club and international-master level, not at the level of leading grandmasters. Marketing absolutism is a signal. When the document writes that "if Black knows what he is doing, things quickly become dangerous for White", it is inflating expectations. The truth depends on White's preparation, something the document cannot measure. Buyers should verify with a database and an engine before adopting it. I recall a VHS tape I found in storage in 2026, when tournaments were suspended by the pandemic. It held footage of the 800m record-holder Nguyen Thi Minh Phuong. I am not comparing chess to athletics mechanically, but I noticed a shared point: every story, large or small, needs a trustworthy source. A record never grows old; it simply waits for someone who knows how to listen. An opening line is the same. It is not new. It is only waiting for someone to verify it with real data. Every stadium I have walked through holds a secret door, and the entrance is always a person. With this DVD, that person has yet to appear. Perhaps he is a genuine KID specialist. Perhaps he is merely a good salesman. We cannot know without a name, without results, without sample games. When the Samarkand document and the 9...a5 DVD are placed side by side, we learn more about how information travels through chess today. The opacity of origin, the blending of advertising and analysis, the claims carried without supporting figures. This is a problem beyond any single product. It belongs to an entire ecosystem busy telling stories to itself. If I were to put one question to the reader, it would be this: when you sit at the board, are you reading an opening book, or are you listening to an advertisement dressed in the clothes of an opening book?
