Three in the morning, my workspace in Hai Phong was lit only by the ceiling fan and the blue glow of the screen. I was rewinding a ten-year-old game, pausing at move three. White played e4, Black answered e5, White brought the knight to f3, and then Black pushed the pawn to d5 — a pawn sacrifice before the opening had even settled. The analysis software flagged that move with an exclamation mark and a question mark. In my trade as a documentary filmmaker, the moments labelled 'problematic' are usually the ones most worth filming.
But that night, what kept me sitting there was not the move itself. It was the way it was being sold.

I found a sixty-minute online course advertising an opening system called the Elephant Gambit. The instructor was an international master, Andrew Martin. The promises were the kind I knew by heart: 'aggressive', 'tricky', 'unorthodox', 'shocking', and above all — 'it will rack up points'. I searched for the data section. There was none. Not an engine evaluation, not a database frequency, not a win rate. All I had were adjectives.
Then I looked at the headline of the piece promoting that course. It named a famous young prodigy — Bodhana Sivanandan. Across all fifteen information points in the article, her name never appears again. I rewound to the start, read every line, hunted for the first letters of that name. Nothing. Not a game, not a result, not a single figure about her.
That was when I understood I was no longer reading an analysis, but a flyer — a flyer pinned to a name to pull readers in.
I trust the board more than the advertisement, because a move does not know how to lie.
Context: an old move sold as a new invention
To be fair, I have to say this clearly from the outset: the Elephant Gambit is not a fabrication. It is real, it has history, and it has players. Black sacrifices a pawn on move two to seize the initiative and space. That is the definition of a gambit: trading material for time. The name 'Elephant Gambit' sounds grand, but its technical nature is plain and old.
What matters is its place on the modern opening map. At the highest level, where every game passes through an engine before it reaches the board, mainline openings still rule. Ruy Lopez, Italian, Scotch, Petroff — those are paved roads, signposted, with thousands of sample games to cross-check. The Elephant Gambit sits at the edge of the map, where people only drop by when they want to surprise someone, not where anyone builds a house.
I have spent thirty-two years watching this industry. I have seen irregular openings live and die in cycles. A strange opening rises, wins a few games at an open tournament, gets mentioned by analysis channels, then vanishes months later once opponents have prepared. That cycle is short, repetitive, and without meaningful exception.
But the course market does not care about that cycle. It cares about demand. And the biggest demand among amateur players has never changed: they want to beat people who prepare better than they do, without having to prepare as much. That is a real, persistent, easily exploited need. The Elephant Gambit happens to sit exactly there.
Sixty minutes. That is the entire length of the course. I asked myself: how long does a serious player spend building an opening system? The answer, for anyone who has sat at the board, is hundreds of hours, sometimes thousands. An hour is not enough to understand an ordinary opening, let alone a gambit as branch-heavy as the Elephant. But an hour is just enough to sell.

Reading the move: what actually happens after d5
I rewound the footage to find what people had forgotten. There was no footage here, only a board, but the principle holds: I wanted to look at the move, not at the pitch.
The name Elephant Gambit is sometimes attached to several move sequences, depending on who is writing. But the line cited in the article — 1.e4 e5 2.Nf3 d5 — is the one I needed to check. After Black pushes the pawn to d5, White has one pivotal choice: take. White accepts the pawn sacrifice with exd5, consolidates, and forces Black to prove that the initiative is worth a pawn.
That is the crux every advertisement skips. In chess, the player who gives up a pawn does not automatically gain an advantage. The advantage only exists if the opponent does not know how to defend correctly. In other words, the value of a gambit lies not in itself, but in the opponent's ignorance. That is a hard truth to sell, and because it is hard to sell, it rarely gets written down.
I tried to picture the numbers. If the opponent is a club-level amateur who has never seen the Elephant, the pawn sacrifice can shock. In a fast game, fifteen minutes a side, the opponent may burn most of their clock trying to find a refutation, and one small error is enough for Black to win. In that case, the Elephant Gambit pays.
But if the opponent is someone who opened a database before the game, or simply has seen the move before, the story flips. White takes the pawn, defends cleanly, and Black must play almost perfectly just to retain a sliver of compensation. What was called 'aggressive' becomes 'needless risk'.
I did not need an engine to see that. I only needed to look at the structure of the promise. An opening whose value is inversely proportional to the opponent's level is not a weapon, it is a lottery ticket. A lottery ticket for fun is fine, but nobody sells a lottery ticket by promising a guaranteed win.
And that is exactly what this course does. It promises to 'rack up points' — an absolute promise. But a gambit can never promise absolutely, because the result depends on who is sitting opposite. This is not a small slip in word choice. It is a flaw in the entire logic of the product.
Sixty minutes and the price of absent data
In documentary filmmaking, I have one rule: if a scene cannot be measured, it does not exist. I count footfalls, I time splits, I record how many times an athlete touches the ground. No number, no scene. With chess, the principle is the same, only the units change.
What are chess's units? There are a few. First is the win rate of an opening in a large database. Second is the engine evaluation at each move, usually reduced to a metric called average centipawn loss — lower is more accurate. Third is the frequency of appearance at top events: which openings top grandmasters choose, how often, and how they fare. Those three are evidence. Without them, the rest is opinion.
The course in the article offers not one of the three. It says the opening is 'tricky', but not tricky against whom. It says 'unorthodox', but unorthodox is not a technical quality — a bad move can be unorthodox too. It says 'shocking', and this is the only place with a grain of truth, because shock is a psychological state, not a chess evaluation. Shocking is easy. Shocking and still correct is hard.
I once wrote a film about a track athlete cut from the national team. I did not write it by calling her 'good' or 'talented'. I pulled out seconds, metres, the number of hurdles cleared, the number of falls. When you have those numbers, no one can argue with you. You do not need to raise your voice, only to turn to the appendix.
Here it is the opposite. There is no appendix. Only a voice. And in sport, a voice without an appendix is usually a voice selling something.
The name in the headline: a bigger signal than the move
If it stopped at missing data, this story would already merit a piece. But one detail made me put down my pen and think longer: the headline was attached to a young prodigy named Bodhana Sivanandan.
She is one of the most interesting phenomena in youth chess in recent years. She plays at an age when most children are still learning to read. In chess circles, that name carries weight. It draws attention. And that is precisely the problem.
Because the body of the article says nothing about her. Not a game, not a result, not a technical remark about her play. The name sits at the entrance, then vanishes in the corridor. This is a familiar trick in the content industry: put a hot name at the top so people click, then take them somewhere completely different — here, a course-selling page.
I am sensitive to this because I have been on the side of the name being used. In 2026, I cut a documentary about SEA Games 29. I chose to focus on the technique of a female athlete who won three gold medals in five days. I counted her footfalls in the final lap and wrote down a concrete figure. My male director dismissed it, saying women know nothing about running, just write it emotionally. I did not argue. I borrowed all the footage, sat down and counted, and cut two minutes of technique. Those two minutes saved the whole film.
The lesson I drew was not 'women are treated badly'. The lesson was: in sports media, people often do not tell the real story, they tell the sellable story. And the sellable story usually leans on a name rather than a number. The name of Bodhana Sivanandan on this course article's headline is a perfect example of that kind of storytelling.
I have no proof that she knows or agreed to have her name used this way. Perhaps it is just an editing error. But whether it is an error or a strategy, the effect is the same: the reader is led into a room bearing someone else's name, only to find an advertising board.
The other view: is the Elephant Gambit useless?
At this point I have to argue against myself, because that is my own rule: every claim, including the counterintuitive one, must face the same standard of data.
If I say the Elephant Gambit is entirely useless, I too am speaking without evidence. The truth is that irregular openings are not useless at all. They have a real place, only narrower than the promises suggest. In blitz and rapid — where time is the greatest enemy of accuracy — a strange gambit can be a real weapon. Not because it is good, but because it forces the opponent to think from move two. Destroying someone else's time is a legitimate tactic.
Some strong players in history have used openings deemed 'unsound' simply to avoid routine. They did not believe in the opening, they believed in their own ability in open positions. So the right question is not 'is the Elephant Gambit good', but 'who is it for, and under what circumstances'.
This is where I genuinely dislike that course. Not because it teaches a gambit. But because it recommends it for the young. Children need foundations, principles, the habit of building a healthy position before learning to trick an opponent. Putting an irregular gambit as a child's core opening hands them a gimmick instead of a foundation. A gimmick wins a few games; a foundation wins a career.
The stadium empty, I turned the sound of spikes into the heartbeat of the film. The board is the same: sixty minutes can make a noise, but it cannot make a heartbeat.
The market of one-hour promises
I look at this story as an observer of the content economy, not as a judge of playing style. Because what is being sold here is not chess. It is the feeling that you can win without effort.
That is a real and growing need. As online chess platforms spread, player numbers surge, and most of them are amateurs playing for fun. They have no coach, no club, no time to study. They have a phone, a small sum of money, and a very human desire: to win the next game. The market for short, cheap, promising courses therefore flourishes. It does not need to be right. It only needs to be appealing.
A sixty-minute course is the perfect economic unit for that model. Low production cost, low sale price, high margin, and no need for technical verification because buyers usually lack the tools to verify. Who will use an engine to check a course they just bought? Very few. And that is why this model survives.
This connects directly to the larger story of modern chess. In an era where every game can be judged by machines, the scarce thing is no longer information but verification. Information is everywhere. Verification is almost never sold, because verification is not fun, not fast, not promising. Someone who buys a sixty-minute course feels they are improving. But the feeling of improving and improvement are two different things, like the feeling of running fast and the seconds counted on a stopwatch.
I trust footage more than testimony, because footage does not know how to lie. And I trust a chess database more than a chess advertisement, because a database has nothing to sell me.
So where does the real question lie?
Strip away the advertising and one purely technical question remains, and this is the question I want to leave with Vietnamese chess players: can the Elephant Gambit survive against an opponent who already knows it?
If the answer is yes, then that course is right, only in a more modest way than it promises. If the answer is no, then the buyer paid for a belief, not a tool. And to answer that question, we need buy nothing at all. We just open a database, find some games by the strongest players who tried it, and count the results ourselves.
I have run hurdles all my life, only never officially timed. Chess is the same: many good moves have never been properly measured, so they persist forever in the grey zone of storytelling. The job of the writer, and of the player, is to drag them into the light of numbers.
Every game is a track: the audience sees the finish, I live in every stride. If people only tell me about the finish line, I will walk the road back myself. And if on that road there are only adjectives, no numbers, then I know I must measure it myself.
