When Vietnamese Billiards Wins the World Title Without a Single Data Sheet

In September 2026, in Binh Thuan, the final of the World Three-Cushion Billiards Championship featured two Vietnamese players standing on either side of the table. Bao Phuong Vinh faced Tran Quyet Chien. The arena was packed, applause rolled down onto the baize, and by the final shot the whole crowd was on its feet.

That night I stayed behind after everyone had gone home. In my hands was a very simple request: an inning-by-inning scorecard. How many innings each player took, how many points each inning produced, what the longest run was, and in which innings the points fell. I asked three different people in the organizing committee. The first promised tomorrow. The second said I would have to request it from the referees. The third handed me a sheet of paper with exactly two lines: the winner's name and the final score.

A world final. The two best players on the planet. Everything that remained from that night, in data form, fit into two lines.

I am not writing this to blame anyone. I am writing because I have spent twenty-nine years working with sports data, and I have learned one thing: a sport can win a world title and still have no memory, if it refuses to write anything down. Football has its own rhythm, and data has its own rhythm. It took me years to learn how to make them stand in the same sentence.

From a pavement table to an arena with stands

Billiards arrived in Vietnam very early, following the French, and then stayed in coffee shops, on porches, under stairwells. Generations of Vietnamese grew up beside a table with worn cloth, a cue slightly warped at the tip, and the sound of balls colliding like rain on a tin roof. That is a shared memory in almost every city.

But there is a line that outsiders rarely distinguish. Pocket billiards, the game played in entertainment venues, is one sport. Three-cushion, also called carom, is an entirely different one in rules, technique, and scoring. In three-cushion there are no pockets. To score, the cue ball must contact at least three cushions before hitting the second object ball. There is no lucky roll into a pocket. Every point must be built with calculation, with force, with spin.

That is precisely why Vietnamese players have gone furthest in this discipline. I remember the early 2010s, when international events began looking toward Southeast Asia. Binh Duong became a familiar stop on the UMB World Cup circuit — the three-cushion World Cup organized by the Union Mondiale de Billard. The event brought the world's leading players to a southern Vietnamese province, competing in an arena filled with spectators, and it created a generation of young players who learned the trade by sitting and watching.

I live in Binh Duong. I have sat in the top row of those events many times, a notebook in hand, recording each inning in scrawled handwriting. The person next to me asked what I was writing. I said I was recording what the crowd would not remember. They laughed. But I know that what is not written down will not exist. Twenty years from now, people will retell the story of Bao Phuong Vinh's title, but nobody will remember how he won it.

What we have already achieved

To be fair: Vietnam's billiards achievements are real, and they are far larger than the infrastructure we actually have.

Tran Quyet Chien, from Binh Duong, spent years among the world's leading players, held the number one position in the UMB ranking at one point, and is a familiar face in World Cup knockout rounds. He plays what people call an "open game" — controlling the cue ball across wide distances, handling long cushions, and being especially good at turning a bad position into a long scoring run.

Bao Phuong Vinh, born later, is a different kind of player. He won the world title in 2026 on Vietnamese soil, in an all-Vietnamese final. That is a milestone few countries ever reach: two players from the same nation contesting a world championship final.

Nguyen Quoc Nguyen, Ngo Dinh Nai, Duong Quoc Hoang — each with a different style, together forming a golden generation any billiards nation would envy. Nguyen Quoc Nguyen with his depth of experience and his ability to hold up under pressure in decisive innings. Ngo Dinh Nai with a solid game and few errors. Duong Quoc Hoang with shots that make spectators hold their breath for their difficulty.

The honors list is long. But if you ask me one single question — which World Cup final did Tran Quyet Chien win against Bao Phuong Vinh, and how, and what was his longest run at that event — I would need several days and might still not find the answer.

That is my point. We have the achievements. We do not have the technical memory.

Three metrics Vietnamese billiards does not have

I work as a football data consultant. There, people talk in xG, in PPDA, in sprint counts, in touch maps. In billiards, we have exactly two numbers published regularly: the average points per inning, and the longest run in a match. That is all.

Those two metrics are like only being allowed to see the scoreline of a football match. You know who won, but you do not know why.

The first metric we lack is a defensive index. In three-cushion, there are innings when a player is not trying to score. He is trying to leave the balls in a difficult position for his opponent, pushing the cue ball into a corner, forcing the opponent into a risky shot. Insiders call these "hiding" innings. These innings decide matches as much as long scoring runs do. But no statistics sheet records them. Nobody can count whether a player won through defense or through attack. In football, this is solved with PPDA and ball recoveries. In billiards, we let it slip away.

The second metric is a scoring map of the table. Watching a good player, people often say he "plays the whole table." But where exactly? What percentage of points come from the right half of the table? How many come from shots across three long cushions? Football has touch maps. Billiards could have scoring maps. We have not built them, because nobody has sat down to draw them.

The third metric is concentration rhythm over time. A top-level three-cushion match can last hours, with dozens of innings per side. I want to know at which inning a player errs. I want to know whether there is a common pattern: is innings 15 to 20 the danger zone, or is inning 30, after a long run, where focus collapses. In football, people know exactly which teams concede between the 75th and 90th minutes. In billiards, we have no data to know the equivalent. And so coaches can only tell students: "try to concentrate harder." Advice that is correct and useless.

Before I trust a number, I ask where it came from. Just like watching a player before making a judgment. The problem for Vietnamese billiards is that we have no numbers to ask.

The value chain of a sport

I often draw diagrams. A professional sport has three layers.

The top layer is where what people see is produced: players, tournaments, broadcasts. Vietnam stands very firm here. We have a world champion. We have international events staged at home. We have audiences.

The middle layer is the operating system: player records, calendars, match data, scouting, youth development, sports medicine. Here we are nearly empty. There is no centralized database of domestic players. There is no seasonal performance tracking file. There is no system recording youth tournament results so that the progress of a 17-year-old can be compared year by year.

The bottom layer is physical infrastructure: billiard halls, tables, cues, balls, cloth, manufacturers, distributors. Here Vietnam has thousands of venues nationwide, a equipment market large enough that international brands must pay attention.

What is worth noting is this: a sport can sit at the top of the top layer for years without ever building the middle layer. It is like a house with beautiful roof tiles but no pillars. The roof still stands, held up by the strength of a few people bracing it. But when those people tire, the roof falls.

The counterintuitive angle: perhaps the lack of data created the champions

I have to say this, even though it seems to argue against everything above.

There is a possibility that the absence of data, of standardized textbooks, of rigid training models, is exactly what produced Vietnam's distinctive billiards style. When nobody tells you the success probability of a given shot, you are forced to trust your hands. When no analytical system says you should play safe in the 20th inning, you are forced to decide by instinct. And that instinct, honed over thousands of hours in billiard halls, is sometimes stronger than any spreadsheet.

But it must be said clearly: correlation is not causation. That Vietnamese players are excellent, and that we lack data, happen at the same time — they do not prove that one causes the other. It is quite possible they are good because they practice a lot, because they have a large billiards community to sharpen against, because they live in a culture that values patience. Those causes are enough to produce champions without a single line of what we call data analysis.

But there is a price attached. Data does not make the current player better. Data makes the next player better, faster. That is the difference between a golden generation and a golden sport. A golden generation will pass. If all it leaves behind is trophies and a few clips online, the next generation will have to start from zero, relearning every secret that should have been written down.

People see the decisive shot; I see the twenty quiet minutes that led to it. That quiet space is not in the scoreline, not in the news, not in the post-match interview. It exists only if someone is willing to sit down and write.

What I have tried to do

I do not want this piece to be only a complaint.

After the final in Binh Thuan, I began recording by hand. I rewatched matches of Vietnamese players on streaming channels, pausing at each inning, and entering data into a simple spreadsheet: inning number, points per inning, longest run, number of defensive shots forced, number of points lost while in an advantageous position. I did this alone, in the evenings, with an old laptop placed beside a cup of coffee gone cold.

The empty stadiums of 2026 taught me to hear the roll of the ball and the fall of a note sheet onto a stadium seat. That period taught me that surrounding context changes results more than people think. Without crowds, home-win rates in European football dropped noticeably. The equivalent question for billiards has never been asked: how much of an advantage does a home player have at a home event? Nobody knows. And because nobody knows, we keep trusting feelings.

My spreadsheet, as of today, holds about forty matches. That is a number too small to conclude anything. But it is enough to show me interesting patterns I had never considered. For example: in the matches I tracked, the average number of innings was usually higher when a player faced an opponent of the same nationality. The all-Vietnamese final had more innings than the earlier rounds. Perhaps because the two understood each other too well, so both chose safer options. Perhaps because the pressure was different. I do not have enough data to say.

But I know I am doing the right thing. Not because I will find the answers. But because if I do not start, someone else will start twenty years later.

What to expect in the next cycle

I am the one who stays with the spreadsheet after the lights go out in the stands — you can call it work, I call it fate.

Looking ahead to the coming season, there are three signals I will track. First, whether any Vietnamese tournament begins publishing detailed inning-by-inning scorecards, even as a simple file. This is the smallest step, the cheapest, and the one with the greatest ripple effect for a sport. Second, whether youth academies begin keeping long-term records for each trainee, so that ten years from now we can look back and see who improved and why. Third, whether a young player is willing to sit down and rewatch himself on video with a notebook, rather than watching only to see whether he won or lost.

None of those three requires expensive technology. They require a notebook, a bit of patience, and a belief that what is not recorded will not exist.

Binh Duong back then had no expensive software, only people who believed a number would eventually find its way. I still believe that. And I still keep the notebook on the desk, open, ready for the next match.
