Eight Empty Columns: Vietnamese Chess Is Missing a Public Data System

On a rainy Tuesday night in Hanoi, I reopened the eight-column file I use for every analysis. Eight pages, eight questions: opening technique; player data; tournament system; competitive landscape; rules and governance; risk; public narrative; industry transmission.

I typed into each cell. Every one returned the same line: insufficient information.

I sat still for about ten minutes. In chess there is a state called zugzwang — it is your move, but every move makes the position worse. People picture zugzwang as an endgame affair, a few cramped squares. It also happens to an entire chess nation that has no reliable record with which to read itself.

Vietnamese chess has big wins. What it lacks is a paper trail.

People say girls know nothing about tactics. So I write for them to read.

I have said that since 2026, when I was sixteen, after my first piece dissecting Vietnam U20's 3-4-3 drew more than forty dismissive comments. Eight years later the workflow is unchanged: open the data file first, write second.

In football that workflow works. Every V.League match produces hundreds of event rows, and I can rebuild a passage of play second by second. In chess I hit a different wall.

Chess enjoys an advantage football does not. Results are absolute: win, draw, loss. And there is a single rating scale run by FIDE since 2026, applied to every registered player on earth. A fourteen-year-old in Hanoi and a forty-year-old in Buenos Aires are measured in the same unit. In principle, this is the most transparent sport there is.

But a rating system measures only outcomes. It does not measure process.

The entire process layer — how a player prepares for an event, how a SEA Games slot is decided, how a twelve-year-old is raised from a summer class to the national team — sits outside every public database.

Vietnam has Le Quang Liem, who won the 2026 World Blitz Championship in Moscow and once reached a peak rating of 2740. It has Nguyen Ngoc Truong Son, who broke into the world's elite as a teenager. It has a women's generation in Pham Le Thao Nguyen, Nguyen Thi Mai Hung and Vo Thi Kim Phung, who delivered most of Vietnam's regional chess medals.

That is the visible part. The invisible part begins immediately behind it.

In chess, the opening is the easiest thing to measure — and the emptiest column in Vietnam.

Every game can be recorded as a PGN file of a few kilobytes, containing every move plus the thinking time behind it. From that you can calculate win rates by opening system, the average number of moves before leaving theory, and ACPL — the average deviation from the engine's best move.

For a professional, ACPL is the equivalent of a midfielder's heat map. It shows where he errs, in which phase, under how much clock pressure. Without it, every judgement about form is an educated guess.

In Vietnam that metric barely exists in public. Games at the National Chess Championship, the national team event, the youth circuit — most are never released as organised PGN. Results exist, on a standings table. But a standings table does not tell you how a game was played.

The consequence: when a Vietnamese player loses a decisive game abroad, we have no basis to say why. We can only guess. And guessing is the one thing readers do not need more of.

I have a habit of rewatching games with commentary off. No noise, no emotion, just squares changing colour. The board is wider when there is no noise. I see it more clearly than ever. But to rewatch, I need a record. In football I have one. In Vietnamese chess, I usually do not.

FIDE publishes monthly ratings for every registered player. That data is open, free and accurate. The problem lies elsewhere.

Classical rating does not decide most events Vietnam enters. Sea Games, Asian Games and regional team events are played largely in fast formats — rapid and blitz. Time shrinks, the gap between players narrows, variance rises. A 2500 player can beat a 2700 player in an afternoon. That does not mean he is stronger. It means he is steadier inside a narrow time window — exactly the kind of information open data does not supply.

I want to know: over the past three years, what is the win rate of Vietnamese players with under five minutes on the clock? The draw rate with the black pieces? How many games were turned around from a losing position? Nobody can answer, because nobody aggregates it.

This is where I have to be blunt. The gap does not come from FIDE or from anyone abroad. It sits in local organisation and archiving. A national championship runs seven days, with arbiters, computers, digital clocks. Exporting a PGN file afterwards takes about ten minutes of work. Its absence comes from a choice, not a technical limit.

Vietnam's tournament structure has every tier: national championship, national team event, a youth ladder from U9 to U20, open events and selection trials. On paper it is a complete pyramid.

But a pyramid only means something if you can count how many people climb each step.

I could not find a single public figure for the simplest question: in one chess intake in a major city, how many children enrol, how many last three years, how many reach a provincial team, how many reach national master level? The conversion rate from summer class to professional athlete is the single most important indicator any sporting nation has. It is also the most absent one here.

The Vietnam Chess Federation oversees both international chess and xiangqi — two disciplines with different competition systems, calendars and resources. In Asia, Vietnamese xiangqi carries very high standing. That dual mandate is an organisational fact, and it carries a data price: resources split, and standardising records for each discipline becomes harder.

Asia is where the picture is clearest, and where the gap shows most plainly.

India has produced a new generation at unprecedented speed. D. Gukesh became world champion in 2026 at eighteen. R. Praggnanandhaa and Arjun Erigaisi crossed 2700 and pushed toward 2800. China has sustained depth in both open and women's chess for two decades. Uzbekistan has produced a world rapid champion.

What matters is not the medals but how these nations retell them. They publish games. They publish analysis. They build content channels where a single game is dissected move by move. As a result, a coach in Hanoi can learn from a junior game in Chennai without leaving the room.

Vietnam leads Southeast Asia and sits among the continental leaders in several categories. But at the very top the squad is thin: the number of Vietnamese players holding above 2600 can be counted on one hand, and that number moves very slowly.

We have a peak. We have not yet proved we have a body.

Chess has a detailed and largely unified rulebook. Three areas, though, are rarely explained to a Vietnamese audience.

Anti-cheating comes first. FIDE bans electronic devices in the playing area, and regulates arbiters and screening. When online events exploded during the pandemic, a large share of play moved to the internet — bringing the whole question of fairness with it. Vietnam staged many online events, but public anti-cheating infrastructure is thin, and disciplinary processes are almost never reported.

Next comes the tiebreak. Buchholz, Sonneborn-Berger, Armageddon. In many events medals are decided by indices spectators do not understand. A medal lost on a secondary index is a media story, and it usually goes untold.

What remains is selection. Which steps lead to a Sea Games or Asian Games slot, and by what criteria — the public has a right to know. Many countries publish this as a document. Transparency at this stage determines the credibility of the whole system.

Vietnam's biggest chess risks are mostly uncounted.

Career risk tops the list. Chess prize money is not a living for most players. An adult professional depends on support from a sponsoring institution, a handful of coaching contracts, or teaching. When income is unstable, the dropout rate at twenty is high — and that rate is measured nowhere.

Burnout among juniors is the same story. Children start at six or seven. Many compete continuously through age-group events. The "junior medal bubble" — champion at twelve, gone by eighteen — is discussed as a feeling, not as a figure.

Systemic risk lies in dependence on a few individuals. When Le Quang Liem or Nguyen Ngoc Truong Son steps away from competition, pressure lands on the next player almost immediately, and there is no metric to show whether that player can carry it.

Vietnamese chess appears in the media on a two-year cycle, tied to the Sea Games and Asian Games. Before the event, expectations are inflated. During it, coverage is dense. After it, silence.

The gap between expectation and result is usually explained by form. That explanation is convenient because it requires no data. A form-based explanation can cover any result, at any event, in any year — which is precisely the sign that it is useless.

In 2026, the series The Queen's Gambit produced a global wave of new players, especially women. In Vietnam the wave was real. Chess classes in Hanoi and Ho Chi Minh City recorded growth. But how much it grew, how long it lasted, and how many stayed — none of that has figures.

There is one parallel between the football transfer market and professional chess: both are dominated by noise.

In football, hundred-million-euro fees for players who have not played fifty top-flight games are naked gambling. In chess the equivalent gamble sits elsewhere: a junior title is amplified by media, then a sponsorship is signed on expectation rather than on conversion rate.

Chess's transmission chain runs along a fairly clear line: junior coaching upstream, events and players in the middle, content and commerce downstream. Vietnam has a strong upstream — many centres, many good coaches, many parents willing to invest. But the middle and final tiers are not joined by data.

One concrete consequence: Vietnamese players increasingly join club leagues abroad — Germany, Czechia, China. That is an important professional flow. Yet the games they play there, the results, and the effect on the national team are barely tracked.

Tactics never lie. Only the reader gets it wrong.

The biggest blind spot here is not missing data. The blind spot is that we are measuring the wrong thing.

In football, possession is the most deceptive metric. A side grinding out 60% with meaningless sideways passes looks in control, while in reality it is passing in areas where nobody scores. Vietnamese chess has an equivalent: the peak rating of two individuals.

That is a lagging indicator. It tells you what happened, not what is coming. It celebrates a golden generation — but a golden generation, statistically, is a distribution tail. It looks like genius, while much of it is clustered luck.

The leading indicator is pipeline conversion: how many enter, how many exit, how long it takes, where they are lost. Nobody tracks it.

There is a fair counter-argument I must include. Many believe publishing games hands weapons to opponents. In the database era, opening secrets last about two weeks. But the counter-argument is not entirely wrong, and I will not pretend it is. A reasonable compromise is delayed release — PGNs published three months after an event. That still beats publishing nothing.

And I have to remind myself of one thing. Data is a shield, not a weapon. Stuffing in thirty numbers instead of three does not make a piece stronger. It only makes the reader more tired.

Sometimes, to understand the game, you must stand in silence longer than others can bear.

I am setting one test for next season, specific enough to be wrong: when the National Chess Championship closes, will every game in the open and women's sections be released as PGN within forty-eight hours?

If yes, this article becomes meaningless within a season — and I will be the first to celebrate.

If not, we will sit here again in two years, telling each other the same story with the same lack of certainty.
