The a5 Move and the Pause Behind the Antidote

In a small café on Nguyen Dinh Chieu Street, I read for the third time the blurb of a chess training DVD. The product talks about the King's Indian Defense, Mar del Plata variation, and a move openly called an antidote to the Bayonet: 9...a5. The copy promises that this move turns a forcing battle into a strategic race that demands little memorization, aimed at players who prefer to think for themselves. I read, closed it, and sat still. There was a pause in me when an opening line was sold as a door out of calculation. I do not distrust the move. I distrust the way it is being sold.

In chess opening theory (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7), the King's Indian Defense has long been the choice of those who concede the center first and strike back from both wings. The Mar del Plata variation — with ...Nc6 and ...e5 — is classified around ECO E97 to E99, its sharpest form, where both sides race on opposite wings and calculation explodes in the middle. In the 1950s and 1960s it was a weapon for many top players. Today its share of elite games has shrunk, but it never disappeared. Based on my experience following games at open tournaments and online arenas, the variation still appears regularly as a surprise choice rather than a foundational system.

The opponent this variation must face is the Bayonet: 9.b4. White uses the queenside to gain space and forces Black to decide early, before the position closes. The orthodox reply remains 9...Nh5. That move opens the position, pushes play into concrete lines, and drags the player back into computer analysis. It is also why many club players dread it: after 9...Nh5, every move can be looked up in advance.

The 9...a5 move the product promotes is a sideline. It has been known for a long time, not a novelty. Read closely, it is a strategic move: Black challenges the b4-pawn and steers the game toward a closed structure with few forced lines. The advertising claims its merit lies exactly there — a stable position with “very few concrete lines.”

Based on my experience following games, 9...a5 is a legitimate branch. It fools no one. Black gains the right to play a slow game, and that is a practical choice for those who dislike cramming. If a buyer expects a cheap weapon against the Bayonet, they receive exactly that at club level.

But there is a vast gap between the marketing and the data. The product offers no sample game, no ACPL, no win rate, no author name, no credential. That is the signature of a product sold by story rather than proof.

This is a familiar format in the Fritztrainer-style training DVD line, common in the German market. It competes directly with free databases and analysis tools. The raw lines are downloadable by anyone; what sells is a guided narrative. Understanding this lets us read promises of an “antidote” with the right level of suspicion.

More striking is the comparative framing: 9...Nh5 “opens the position and makes computer analysis important again,” while 9...a5 leads to “sound positions with very few concrete lines.” This framing creates a convenient opposition: what must be memorized versus what can be thought through. I understand why it appeals. A large share of chess learners seek a sense of autonomy at the board, and selling that feeling means selling the hardest thing to verify. The advertising does not target deep specialists; it targets the self-image of the self-taught player — a very familiar identity-based marketing angle.

There is one claim I want to read very slowly. The advertising says computers often do not know how to handle these complex strategic positions. That sentence is entirely familiar from the pre-AlphaZero era. With today's neural-network engines, the long-horizon King's Indian positions are evaluated far better than the sentence implies. It is dated marketing language, though it still works on listeners. It turns the computer into a villain, then turns the product into the human escape route.

Here I must mention a detail that made me stop while reading. The promotional text in my hands carried a headline about a team event in Samarkand, round 2, with “all top teams winning.” Yet the entire body discussed a chess DVD and the 9...a5 move. Two unrelated texts had been spliced together. If a journalist copies it verbatim without checking, they will report on a tournament in Uzbekistan while actually advertising an opening DVD. The damage lies here: the opening may be fine, but the event is attached to the wrong place, and the reader has no way to notice.

There is something I always remember when rereading old commentary about the chess world: The true death of a golden generation is when we stop remembering them. For openings this is even truer. A forgotten line does not die because it was refuted; it dies because no one tries it anymore. The Mar del Plata was once the pride of an entire school, and now it exists mainly as a surprise weapon. The 9...a5 line promoted by this product follows the same law: it revives the moment someone spends time on it, and fades when attention withdraws.

If this theoretical line gets played heavily in tournaments, a White-side response will appear within one theory cycle, and the “antidote” story will flip. That is the nature of openings: every antidote is born alongside a counter-antidote. The product is not wrong to sell a strategic option; it is wrong to imply that this option closes that door forever. In chess, no door stays closed for long.

I wonder why claims like “if Black knows what to do, things quickly become dangerous for White” appear in a text so thin on numbers. The answer likely lies in how theoretical products are sold: persuading the buyer that the gap between their current level and safety is one click away. That feeling is not entirely wrong. It is simply unproven.

A note for readers

For club players, the real value of 9...a5 lies not in refuting the Bayonet but in opening another road worth walking. Still, readers should build the habit of checking three things before buying a theory product: who the author is and what they have played in that line; whether sample games with engine evaluations exist; and whether the line has been played in recent tournaments. Those three questions are simple, but they filter out most of the flashy marketing.

The product may still be a good study resource. I am not writing to bury it. I am writing to put it in its proper place: a useful sideline, packaged in outdated language. Generations will pass, but the poem about them keeps being written. The same holds for openings: the 9...a5 line will be forgotten by a later generation, then remembered again by another advertisement. That circle is not deception. It is simply how the chess world keeps its memory.

What I want readers to carry away is a healthy suspicion. A good move does not need to be called an antidote to be worth studying. And an advertisement, however accurate about the board, can never replace a real game — with names, dates, and moves that cannot be denied. As the chess industry expands, players need honest chroniclers more than loud sellers. The echo of an empty stand still has its value: it forces us to listen for ourselves, instead of trusting what is printed on the DVD cover.
