The 2...d5 of a Sixty-Minute Course, and a Name Put in the Wrong Place
Nha Trang, April. Seven in the evening, sea wind slipping through the open window of a small chess club on a street few people walk past. Seven people in the room: three grey-haired men like me, four children. The boards are stacked in a corner, and the whole room is bent over a single phone.
A fourteen-year-old boy hands me the device. The screen lights up with a video exactly sixty minutes long, its title in bold: Elephant Gambit. He asks: "Should I learn this?"
I look at the line above the title: the name of a young English player of Indian origin, Bodhana Sivanandan. Then I scrub through the full sixty minutes. In all that time, the name never appears again.
Every stadium I have walked through holds a hidden door, and the entrance is always a person. The same goes for a chessboard. This time the door was a fourteen-year-old boy, and behind it was a story that had nothing to do with any move.
Context: a market for opening instruction that never sleeps
In close to fifty years sitting at the board, and more than twenty behind a camera, I have grown used to a rhythm: whenever Vietnamese chess gains a new layer of players, the instruction market blooms again. The latest wave began in the early 2020s, when amateur tournaments moved online and tens of thousands of Vietnamese accounts appeared on international chess platforms. Club players in Nha Trang, Da Nang and Hanoi started buying opening courses in foreign currency, something they had only heard about a decade earlier.

Most of those courses are written by European masters. One of the most familiar names is Andrew Martin, an English International Master and author of dozens of opening repertoires sold as online courses. The product in that boy's phone is one of them: a Black repertoire, sixty minutes long, built around a move most Vietnamese players have never seen across a tournament board.
Sixty minutes. That number is worth pausing on. A serious repertoire for a complex line usually runs three to eight hours of video, split into sections, with notes and exercises. Sixty minutes means a product designed for the fast learner, the fast payer, the person who will use it this week — a real and growing segment in Vietnam.
Above that product sits a headline carrying the name Bodhana Sivanandan. Born in 2026, English of Indian descent, she was mentioned widely by the international chess press in 2026 when she became the youngest player ever to represent England at the Chess Olympiad in Budapest. A name like that earns a great many clicks. It simply has nothing to do with 2...d5.
In the age of the thirty-second video, it took me three months to hear one man tell the story of a 400m race from 2026. Here, it took me sixty minutes to understand that I had just read an advertisement dressed as analysis.

Core: what 2...d5 actually is
The game begins 1.e4 e5 2.Nf3. At this point, instead of the familiar defences 2...Nc6 or 2...Nf6, Black plays 2...d5. The d-pawn advances two squares, attacks White's e4 pawn, and willingly steps into the loss of a pawn. If White takes — 3.exd5 — Black continues 3...e4, pushing the e-pawn to chase the f3 knight and reclaiming space and tempo.
That is the whole idea: trading a pawn for time and space on move two, before the opponent can settle. In opening theory this is a gambit centuries old, part of the unorthodox family. It is not a new invention, not the discovery of any analysis room, and not a line recently awakened by computers.
The central technical question is simple: after 3.exd5 e4, can White keep that pawn healthily? At high level, the answer is yes. White brings the queen to e2, develops the knights, restores the pawn structure, and hands back part of the advantage to steer the game toward solid ground. Black gets activity, open diagonals, and traps that less experienced players fall into easily. But "has traps" and "has an advantage" are two different things, and this is exactly where course sellers swap one for the other.
This is also where sixty minutes is not enough. A serious Black repertoire here needs at least three main branches: White takes and tries to hold, White takes and gives back, and White declines by playing in the centre another way. Each branch splits again, and each sub-line has forks where a single move in the wrong order collapses everything. Sixty minutes is enough for an introduction. An introduction usually skips precisely the lines a strong opponent will choose.
Most striking of all is that not a single line of data is presented. No engine evaluation, no win rates, no frequency of use among leading players, no precise metric of any kind. Every argument in that promotional piece is an adjective: sharp, tricky, strange, surprising. Adjectives are not data. In my trade, a record nobody can verify is only a story; an opening with no data is only a promise.
Who plays it? In public databases, 2...d5 is nearly absent from top-level events with long time controls. It lives on another floor: blitz, rapid, amateur tournaments, games where opponents cannot recall the theory and have no time to calculate. On that floor it genuinely has value — and on that same floor, its value is inversely proportional to the opponent's strength. The weaker the opponent, the likelier the trap springs; the stronger, the likelier the pawn is simply held and handed back at the right moment.

In Vietnam the gap between those two floors is stark. A player like Le Quang Liem or Nguyen Ngoc Truong Son prepares openings with engines, with databases, with hundreds of tagged games from the opponent. A boy at a Nha Trang club prepares with a sixty-minute video, watched twice the night before the tournament. The two worlds share a board, but they are playing two different sports.
The course producer understands this perfectly. He does not say the product is for grandmasters. He says it is for "young players and club players." That is a market positioning statement, not a technical verdict. And in that sense it is entirely accurate.
The counterintuitive part: the problem is not 2...d5
I will say something much of the chess world does not want to hear.
The move 2...d5 is not guilty. An offbeat opening, taught honestly, is a legitimate tool. Amateur players are entitled to a surprise weapon; their games last forty minutes, and nobody sits recalling theory to move twenty. The point worth arguing lies in how the move is sold, not in the move itself. The course promises to "rack up points" with a very clever condition attached: "if used with discretion." That condition turns the promise into something that cannot be wrong — because if you lose, the fault is that you did not use it at the right moment.
But there is a deeper layer, and this is the real story. A name like Bodhana Sivanandan appears in the headline of an article about an opening product, then vanishes entirely from the body. She contributed no move to the repertoire, is quoted nowhere, is mentioned not once. Her name is there to do exactly one thing: make a reader click.
In my trade as a documentary writer there is one non-negotiable rule: never attach a person's name to a story in which that person does not appear. For the sake of trust, not for the sake of any moral argument. A false headline ruins a whole archive, and for a sport whose media system is still young, as chess is, trust is worth more than every pawn on the board.
Fairness also requires the reverse point: those who rush to declare offbeat openings the refuge of the weak are missing something. An amateur's game and a grandmaster's game are not the same game. There, surprise has real value, and a good coach has every right to teach it. What that coach has no right to do is turn a tactical choice into an unverifiable promise, then hang it on the name of a ten-year-old girl who is still building her own career.
What remains
I still keep that sixty-minute video on my phone. Not for 2...d5, but for the boy who handed it to me.
He asked whether he should learn it. I told him: learn it. Watch all sixty minutes. Then watch another sixty to understand why it does not work at a high level. A strange move does not teach you how to win; it teaches you how to ask. And in a chess culture where everything is now sold on speed, the most valuable thing left is the time to ask.
A record never grows old; it is only waiting for someone who knows how to listen. So is an opening. But a name put in the wrong place waits for no one — it only quietly wears away the one thing the whole sport needs: the trust of the person sitting on the other side of the board.
