The Empty Data Stratum Beneath Vietnam's World Billiards Title

On the night of the 2026 world three-cushion final in Binh Duong, I sat in the seventh row on the left of table one, where the overhead light turned the blue cloth almost silver. Tran Quyet Chien bent over his cue. The hall held its breath in a very Vietnamese way: nobody shouted, there was only the ceiling fan and someone dragging a plastic chair across the tile.

According to the result published by UMB, Bao Phuong Vinh won that final. A cueist born in 2026, raised inside the club system, beat the man who had once held the world number one ranking. The domestic press called it a historic moment, and they were right.

The next morning I opened my laptop in the hotel and tried to rebuild the match with numbers. I needed four things: innings per player, average per inning, highest run of the match, and innings lost to defensive errors. For a televised football match, those four things take three minutes. For a world billiards final played four hundred metres from where I sat, it took four hours and I still had half of nothing.

People remember that night through emotion. I remember it through an empty file.

The sediment layer of a World Cup is not in the trophy. It is in the players forgotten when the lights go out. To know who was forgotten, someone first has to write it down.

Vietnamese billiards contains a paradox that is obvious to insiders and almost invisible to outsiders: the achievements at the top are far higher than the information infrastructure at the bottom. We have a world champion, we have a cueist who once stood number one in the world, we have a World Cup stage held on our soil almost every year since the mid-2010s. We do not have a single public database that can answer the simplest question: where is Vietnam's eighteenth-ranked young cueist playing right now, what is his average, and has he improved or regressed over the past twelve months.

Three-cushion carom is the flagship discipline, and it entered Vietnam by a very particular route: through small clubs in alleys, where a billiard table is the family's asset, where hourly rental is the household income, where a fourteen-year-old boy is allowed to play free in the mornings because the owner saw something in his hand. That system produced a world champion. It also produced thousands of cueists whose names nobody outside the district knows.

The careers of Tran Quyet Chien, Ngo Dinh Nai, Nguyen Duc Anh Chien and later Bao Phuong Vinh show the model works. But it works as apprenticeship, not as industry. The teacher remembers the student with memory, not with a file. The club remembers achievement with trophies on a wall, not with a spreadsheet. And when a cueist moves from one district to another, the entire record of him disappears.

Above, UMB publishes rankings and a handful of indicators for the elite group. World Cup stages are filmed by Kozoom and distributed to the international market. But that is the atmosphere, not the ground. Between the two layers sits a thick silence, where most of a Vietnamese cueist's career unfolds without leaving a trace anyone can look up.

I came to billiards from football. In 2026, when the V-League was suspended by the pandemic, I built a spreadsheet tracking 47 youth players from the PVF academy and the HAGL academy, logging height, appearances, minutes, expected goals. That spreadsheet taught me something scouting never told me: I found 47 gems not because I have a sharp eye, but because I am far too lazy to trust the reports that already exist. When I moved to billiards, I brought the same attitude and discovered there were no reports here to distrust.

One public number, and only one

In three-cushion, the most cited figure is the average per inning, the moyenne. It is the only thing that appears consistently on the scoreboard, in the rankings, in the newspapers. A cueist averaging 1.4 is considered strong at national level. 1.8 is continental. Above 2.0 is world class.

The problem is that moyenne is an average, and an average conceals more than it reveals. Two cueists can both finish a match at 1.5 with completely different careers. The first reaches 1.5 by steadily scoring three per inning for most of the match. The second reaches 1.5 with four runs of eight and twenty empty innings. The final number is identical. The curve is opposite.

When I sat down with recordings of national championship matches, I counted the distribution of points per inning by hand. The result forced me to revise how I evaluate players. Some young cueists average 1.3 with a very low standard deviation, meaning they never collapse, and that is a far better foundation than a cueist averaging 1.6 thanks to two lucky ten-point runs across an entire tournament.

The second indicator I need is the average number of innings required to close a game. It measures finishing ability. In carom, a defensively strong cueist can keep an opponent low, but if he needs twenty innings to complete fifteen points while his opponent needs twelve, his defensive strategy is masking a finishing hole. Nobody publishes that indicator in Vietnam.

The third is the error rate in active defence, meaning innings where a cueist deliberately pushes the balls into a difficult position for the opponent but leaves a chance open. This is the indicator that separates a good defender from a lucky one. In European setups, analysis teams have this data. In Vietnam, I count it by eye, rewinding each phase, and I know my margin of error is not small.

A ranking with no middle floor

UMB publishes a world ranking. But it only means something for a very narrow group at the top. Below that threshold, a Vietnamese cueist can win three consecutive national titles and still not appear anywhere searchable.

I once tried to build a hypothetical domestic ranking for about forty cueists whose names I knew. I gave up after three weeks, because the only criterion I could verify was results at open tournaments, and even those results are not centrally archived. Every club posts in its own format; some only post a photo of the draw on a personal Facebook page; some delete it after a month.

What is the consequence? A nineteen-year-old cueist who wants to know where he stands against his own age group has no way to find out except by asking people one by one. A coach evaluating a prospect must rely on hearsay. A sponsor deciding where to put money must look at trophy counts, and trophies say nothing about a development curve.

What I counted in Hai Phong

Last weekend I walked a loop around my neighbourhood and counted eleven billiard clubs within roughly three kilometres. Sixty-three tables in total. Four clubs had competition-standard three-cushion tables; the rest were pool tables and smaller carom tables for casual customers.

I went into the four carom clubs and asked the same question: do you keep records of internal matches. Three said no. The fourth had a notebook, but it only recorded the winner's name and the stake, no scores, no innings.

The owner of the fourth club, past fifty, told me about a boy who used to play there seven years ago. He remembered the boy's name, remembered that he ran ten points in a handful of innings, remembered when he left. He did not remember the boy's average, because nobody had ever calculated it.

That is the complete archive of a talent in one district of Hai Phong. The memory of a club owner.

The twenties of a cueist are like a young geological layer: beautiful on the surface, prone to collapse if the base is not checked. At that age, technique is enough to produce shots that make spectators stand up, but the foundations of fitness, psychological stability and tolerance for a dense calendar remain untested.

In football, I can test that base with injury data, minutes played, running load. In billiards, I have no equivalent. Nobody records how many hours a young cueist played this month, how many consecutive events, and how his technical quality changed after the third day of a five-day tournament.

One specific question I once posed and could not answer: after a long tournament, by what percentage does a young cueist's defensive quality decline. In tennis, this is measurable. In carom, people only say with feeling that he ran out of gas.

Scouting networks in places like Vietnam share a feature I always view with caution: they find geniuses and they also manufacture lottery tickets. Every time a young cueist rises, ten families decide to pull their children out of school to pursue the trade, based on a sample size of one. There is no data to tell them the actual probability of success, because nobody has ever counted how many tried and quit.

That is why I keep writing reports by risk tier rather than by upside. The spreadsheet comes before the dream. I do not draw the future; I only measure the dust of time settling on each indicator.

Money follows data

There is a causal link Vietnamese billiards rarely states outright: sponsors do not fund what cannot be measured.

A company putting money into a football tournament receives viewership data, engagement data, estimated brand value. Putting money into a billiards tournament, it receives an opening ceremony and a few photographs. No audience data, no player data, no growth data.

The result is that the market value of a top Vietnamese cueist in sponsorship terms is far below his actual competitive value. A man who beats the world champion can still have no meaningful sponsorship contract, because nobody can prove to a board of directors that the investment pays.

I once took part in appraising a sponsorship proposal for a club. We had photographs, videos, testimonials. We were missing exactly one thing: a table showing how many young cueists had registered for training at the club over the past three years. Nobody had kept that number. The proposal was shelved.

Two billiards cultures to compare

In the Netherlands and Belgium, carom is a sport with a structured national league system, promotion and relegation, clubs that pay cueists, and public statistics published season by season. A twenty-year-old cueist there knows exactly where he ranks in the system, what his nearest rival's strengths are, and which indicator he must improve to move up.

In Turkey, South Korea and Japan, the state and the federation invest in youth systems with record-keeping, training centres and long-term tracking programmes. That is why those countries keep producing cueists across multiple age cohorts rather than producing a few exceptional individuals and then going quiet.

Vietnam differs in that the grassroots technical base is very strong. What we have is dense club coverage, a popular billiard culture, and a generation of cueists who learned the trade by sitting and watching better players. What we lack is the layer of record-keeping that turns what happens in those clubs into transferable knowledge.

Suspicion is not for denial; it is for digging deeper before announcing a discovery. I do not doubt the fact that Vietnam has a world champion. I doubt our ability to reproduce a second, third and tenth world champion through a process rather than through a single lucky alignment of genes and circumstances.

Someone is paying for the emptiness

The counterintuitive view I believe is correct: the data gap in Vietnamese billiards is not a technical fault requiring immediate repair. It is a subsidy, and several parties collect it.

Who benefits? First, the small clubs. No public data means nobody can compare the coaching quality of different establishments. An owner can claim his students are good without proving it. Second, parents. No data on probability of success means hope never has to face a number. Third, the media, myself included, because emotional stories are always easier to write than spreadsheets.

That subsidy has a price. It keeps the sport cheap, accessible, and capable of supporting many people. If tomorrow we published everything, alongside a transfer market and a youth ranking system, we would immediately create a side effect: small clubs without real coaching capacity would be eliminated, and families currently steering children into the trade would see the true odds.

There is a counterargument I raise against myself: publishing data early can create a more sophisticated lottery market. Once you have a youth ranking, you create a new class of brokers who specialise in evaluating fifteen-year-olds, and that class has an incentive to inflate in order to sell. In football I have seen enough of early valuation: an eighteen-year-old tagged at three million euros before thirty appearances, and that pressure crushes him faster than any injury.

I still lean toward publication, for a different reason: information asymmetry always favours the stronger party. When data does not exist, the beneficiary is the person with connections, with voice, with the ability to place a name on a list. The young cueist in a distant district has nothing, not even a number to prove he deserves to be watched.

What troubles me most is not the quantity of data. It is the number of people who know how to read it. We can buy equipment, license software, build a database in two years. But if nobody at the club knows that a cueist with low scoring variance is worth more than a cueist with a high but volatile average, the data just sits there and rots.

I have seen this in football. Academies have software, charts, reports. The final decision is still made by the gut of whoever holds authority. Data becomes decoration, a way to legitimise a decision already taken.

If Vietnamese billiards follows that path, we will have more paperwork and no more champions.

There is a much cheaper direction, and I think a more feasible one: start by recording what already exists. Every club, one notebook, four columns per internal match. Name, points, innings, innings lost to defensive errors. No software. No funding. Only a shared convention so that after three years, data from two hundred clubs can be stitched together.

Three years is the time I need to answer the question I have been carrying since that night in Binh Duong: of the ten best young cueists in one cohort, how many actually go on, and which signals at seventeen predict it.

If by 2029 nobody can answer that question, then Bao Phuong Vinh's title will remain a beautiful archaeological find, standing alone in an empty layer, with nothing beside it to compare and nothing beneath it to hold it up.
