King's Indian Defense: The Bayonet Attack and the Sale of Strategic Patience

On the computer screen in the small apartment overlooking the Han River, I slow-motioned an opening analysis clip to the ninth frame. The board froze exactly as 9.b4 appeared — the Bayonet lance, the weapon that generations of White players have used to drive into Black's queenside in the King's Indian Defense. At 55, I still sit for hours in front of such frames, counting each move, measuring each square, wondering why a pattern more than half a century old still sparks arguments. Pull back the curtain on speed, and I meet a whole generation running — but this time it is a generation running slowly, deliberately slowly, trying to escape the treadmill of forced lines that engines have memorized. Recently, an opening product in DVD form chose the move 9...a5 as its banner, selling it as an antidote to the Bayonet lance. That story deserves dissection not because it is right or wrong, but because it exposes a paradox of modern chess: people are reselling each other the very patience that machines taught them to despise.

To understand why a move on the a5 square deserves discussion, we must step back and view the whole landscape of the King's Indian Defense, or KID as the international abbreviation that Vietnamese players increasingly use. This is a system born of hypermodern thinking: Black voluntarily yields the center to White in the early moves, builds a Bishop on the g7 diagonal as a spine, and from there counterattacks the very bulky center the opponent has erected. The basic moves run 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7, and after both sides settle their formations, Black launches ...Nc6 plus ...e5 to open a front. The beauty of the system lies in turning temporary weakness into long-term advantage; the difficulty lies in demanding that the Black player calculate beyond a simple exchange of blows.

The thorniest branch of the KID is called Mar del Plata, a variation named after the Argentine city where it raged in the mid-twentieth century. There, both sides send troops to opposite wings: White advances on the queenside, Black counterattacks on the kingside, sometimes even with the Rook behind the f-pawn for an extra push. The outcome is usually decided by who reaches the opponent's wall first. By the classification of the opening encyclopedia, Mar del Plata falls in the range E97 to E99, a territory where anyone who enters must accept sweating over every move rather than riding a prewritten script.

For decades, White countered Mar del Plata by playing tightly on the queenside, maintaining balance and waiting for Black's lapse. But in the late twentieth century, a new school emerged with the opposite philosophy: instead of waiting, attack first with the b-pawn advance to b4, pushing the black Knight on c3 to the rim and drilling into Black's rear structure. That is the Bayonet Attack, peaking at the ninth move 9.b4. The lance denies Black the leisure to deploy, forcing an immediate decision about the nature of the position. And for years, the accepted answer was 9...Nh5, the knight leaping to h5, ready to trade and bring the kingside Bishop into the fight.

This is precisely where the opening product's story enters. The chess theory market operates by a very particular logic: whenever a line becomes popular, someone sells an antidote to it. The Bayonet Attack became so popular that club-level amateur players sought every way to confront it. So an author chose 9...a5, the queenside pawn advance blocking the lance, as his answer. The marketing message was clear: instead of plunging into the specific, calculation-heavy lines after 9...Nh5, the Black player should choose a strategic position, where the forced lines are few enough to be almost unmemorable, and where both sides have a chance at balance.

That pitch has a reasonable psychological anchor. Many amateur players are tired of cramming dozens of variations only to have the opponent reply with a move deep in theory proposed by an engine. The feeling of being suffocated by theory is real, and any product promising liberation from that burden holds appeal. But here we must separate two things: a widely known move is not an invention, and a secondary move is not inferior merely because it is secondary. 9...a5 is a branch that has existed in the theoretical store for a long time, not a novelty. The real value of the product lies not in inventing a line, but in repackaging an old strategic branch into a system that is easy to remember for players short on time.

When comparing 9...a5 directly with 9...Nh5, the picture emerges as two opposing personalities. The move 9...Nh5 is a forced response: it opens the position, pushes both sides into specific lines, where the engine again becomes the supreme arbiter. But 9...a5 is a strategic response: it does not immediately solve the queenside problem, but poses a new question for White about how to handle the pawn structure, while keeping the position relatively closed so Black has time to pivot to the kingside. In other words, 9...a5 trades forcing power for flexibility. That is a philosophical choice, not a purely technical one.

However, this is where the caution of someone who has followed chess for four decades is needed. I once sat up nights analyzing every lap of a Vietnamese female track athlete through slow-motion software, only to realize that a performance number never tells the whole story. In chess it is the same. The claim that after 9...a5 only "very few concrete lines" remain is a seductive sentence, but it lacks any database foundation. There is no win rate, no draw rate, no move-quality index, no sample game cited. An opening course that offers no statistic at all keeps its promise at the level of advertising, not yet at the level of proof.

The second weakness, and perhaps the more serious one, lies in how the product frames the contrast between human and machine. It argues that 9...Nh5 opens the position, forces the lines, making engine analysis important again; whereas 9...a5 leads to sound positions that engines often do not know how to handle. This is pre-AlphaZero thinking, from an era when people still believed engines were only good at lightning calculation and weak in long-term strategic positions. The reality of the 2020s has inverted that belief. Neural-network engines today play closed KID positions with a subtlety that astonishes grandmasters; they see plans that take humans dozens of moves to recognize. The argument that "machines don't understand" was once a seductive rhetorical weapon, but it is now dated.

There is a paradox worth pondering here. It was the engine that pushed elite chess into a theory explosion, panicking amateur players before a vast mountain of knowledge. Then it was also the engine, through free analysis tools, that made every line so easy to look up that a DVD product must compete with something other than raw data. What does the product sell? It sells guidance, sells lesson structure, sells the reassurance of a learner who believes he is following a path selected by an expert. But the producer attaches a hollow promise about defeating the engine on strategic ground. People talk of speed, but I find time — and in this case, time has outrun the advertisement itself.

On the risk of obsolescence, we must confront the nature of the Bayonet branch. It is a thoroughly plowed territory. Any antidote to a popular line will soon be reverse-engineered by the opposing side. Chess history is littered with "ultimate weapons" that lived a few months before being neutralized. If 9...a5 truly becomes a threat at a high level, it would take only one theory cycle for White players to find a counter. By then, the psychological edge of the DVD buyer will evaporate, and the only thing left will be the underlying strategic principles — which are free and available everywhere.

Another layer the reader should note lies in the customer segment the product targets. It is not aimed at elite grandmasters, but at players who see themselves as independent thinkers, who dislike rote learning, who like to sit at the board and find their own path. This is identity-based positioning, a classic marketing strategy: people do not buy a move, they buy an image of themselves. Everyone wants to believe they play chess "with their head", not as a machine cramming variations. A product that pins that label onto itself touches exactly that identity craving. But strategic freedom is only valuable if it comes with genuine judgment; otherwise it is just an excuse to avoid studying.

So how should a serious player face this kind of product? Before spending money, three questions are needed. First, who is the author, what results do they have in this very Mar del Plata branch, have they played Black in real games against the Bayonet. Second, does the product cite any specific high-level game, include engine evaluations, or consist only of bare assertions of equality. Third, are the sample lines really as "few" as advertised, or is that just understatement to sell. If all three questions lack satisfactory answers, the product deserves to be placed beside the free opening libraries online, where data is transparent and self-updating.

At a deeper layer, the story exposes a problem of information integrity. The source document I encountered already showed a suspicious sign: the title pointed to a team event in Samarkand, while the body was a promo blurb for a King's Indian opening DVD. The two pieces are entirely unrelated. In journalism, such a mismatch is a red flag, reminding one to trace the origin before citing. This is also a familiar lesson of the age of information chaos: content can be spliced, titles can be misassigned, and the alert reader is one who always checks the source.

Broadly viewed, the incident sits within a stable movement of the chess industry: the opening-theory publishing business. This is a modest but durable revenue stream that supports many authors and online learning platforms. To survive, a product must differ not by the correct move — since anyone can look that up — but by its ability to guide and narrate. A good course wins not through lines, it wins by helping learners understand why a move exists. And if anything positive emerges from the 9...a5 story, it is that Vietnam now has a generation of young players knowledgeable enough to judge an opening product themselves, rather than buying on advertising.

I recall the days of building video series analyzing every lap of a female track athlete, when young people called me the technical reporter uncle. Back then I learned that a performance number only matters when placed in the context of a story. In chess too: an engine index is valuable only when the reader understands what it hides. In the silence of the stands, the future wears running shoes — but at the board, the future walks with quiet steps, moves that look dull yet decide the whole position. 9...a5 is such a step: slow, discreet, and extremely easy to underestimate.

What unsettles me is not the technical value of that line, but how its story is sold. In a world where every line can be dissected by engines to the end, the real human advantage no longer lies in knowing the most, but in understanding one branch deeply and knowing when to leave it. A wise player does not buy an antidote; he builds a filter. He learns to read a closed position, to shift the attack axis, to accept that some games will be decided by a small move on the board's rim.

The 9...a5 story therefore does not end at the question "is this move strong". It opens a larger question: when machines have taught us almost everything about the correctness of each move, what is left that humans can sell to humans? The answer, I believe, lies in patience — the ability to sit before a position with no clear outcome, and still find a path. Any product that genuinely teaches that is worth the money. As for products that merely repackage a few old lines and slap on the label "antidote", we can read them as reference material, and move on.

Some will ask whether I use 9...a5 in my own games. The answer is yes, and no. Yes, because I believe in the value of keeping a closed position when I do not want to be dragged into a calculation race my opponent has prepared better. No, because I will not choose it based on a DVD's advertisement, but on the specific traits of each opponent and my own playing style. That is the difference between a theory consumer and a theory user. The consumer buys answers; the user buys questions. And in chess, whoever knows how to ask the right question always holds the long-term edge.

Back to the frame frozen at the ninth move on the screen. The board is still there, silent, waiting for my decision. I turn off the computer, brew a cup of tea, and think about what I have just seen. On one side is the Bayonet lance — a symbol of youth, of the ambition to attack from the ninth move. On the other is 9...a5 — a symbol of patience, of the belief that the position will tell its own story if we know how to listen. Between these two symbols there is no winner or loser. There are only two different ways of seeing the same game, and both are right in their own circumstances. The only wrong thing, if any, is someone trying to sell us one symbol as if it were absolute truth.

Chess has walked with me for more than half my life, from games organized back home to analyses sent around the world. I once believed the value of a move lay in the result it produced. Now, with greying hair, I believe something else: the value of a move lies in the question it plants in the opponent's mind. 9...a5 plants a question about patience. The Bayonet plants a question about ambition. And the best player is not the one who can answer every question, but the one who knows which question deserves an entire evening. The stands are empty, but the board is not silent — it only waits for someone still enough to listen.
