In Search of Numbers That Know How to Dance: Vietnamese Billiards from Sidewalk Cafés to the World Crown

2:47 in the morning. A billiard hall tucked deep in a small alley off Nguyen Thien Thuat Street in Nha Trang, four tables still lit, three empty. The ceiling fan turns slowly, like an old man telling a story. The smell of cue chalk mixes with the damp of sea wind — a smell anyone raised on the central coast recognises even with their eyes closed. The man at the third table is H., thirty-two years old, an air-conditioning repairman by day and a three-cushion billiards player by night. He is thin, wearing a t-shirt faded more by washing than by wearing. His left hand rests on the cushion like someone holding something very fragile. There are only three balls on the table: one white, one yellow, one red. The cue ball sits tight against the long cushion, almost glued to the cloth. He needs three cushion contacts before he touches the target ball. Not two. Three. It is one of the hardest patterns this sport can lay in front of a player. He bends down. The cue line is straight, the shoulders loose, the wrist locked like a joint lubricated by twenty years of repetition. He shoots. The cue ball hits the first cushion, swings to the second, brushes the third, then touches the yellow ball. One point. He straightens up, walks a lap around the table, resets the position. Then seven more points. Then he stops, because it is his opponent's turn. His friend on the red plastic chair, pencil in hand, says quietly: "Nine points. Nice shooting." Nobody records it. No camera. No electronic scoreboard. No statistics software, no analytics department, no one typing each shot into a spreadsheet. The next morning, those nine points dissolve into the humidity of the coastal city, and I am the only person left who remembers they existed. I sit at the corner table, my black coffee long cold, and I think about what I have pursued for forty years: how to tell the story of a match that nobody measured. The match truly begins from the moment nobody is touching the balls any more. When the cue ball stops, when the player straightens up, when the scorekeeper taps a finger lightly on the table — that is when the match actually happens, in a place no scoreboard records. I learned to read matches through metrics, but only when those metrics know how to dance. And tonight, in this hall, H.'s nine points have no metrics at all. Vietnamese billiards has travelled a distance over the past two decades that very few sports in the region can match. From tables set up in front of houses under hot tin roofs, where people played to kill time between shifts, this sport has climbed to its biggest stage: a world championship final with two Vietnamese players standing on opposite sides of the table. Tran Quyet Chien won the UMB World Three-Cushion Championship in Ankara, Turkey. In that final, the man across the table was a compatriot nearly two decades younger: Bao Phuong Vinh. An all-Vietnamese world final, in a sport that thirty years ago nobody in Vietnam would have dared imagine. I remember that night. I sat in front of the screen, a notepad in hand, trying to record every shot. By the twelfth point I put the pen down. I could not keep up. Not because my hand was slow, but because there was no data source to cross-reference, no live statistics feed, no rolling average updated after every inning. I had to do all of it by eye. That is one of the great paradoxes of Vietnamese billiards: the summit of this sport has reached world level, but its data infrastructure is still on the ground, exactly where the sidewalk billiard cafés begin. Consider the scale of the movement. According to estimates from people in the domestic billiards business, there are tens of thousands of active billiard tables nationwide, from three-table cafés in coastal towns to clubs with dozens of tables in Hanoi, Ho Chi Minh City, Da Nang and Binh Duong. Every night, hundreds of thousands of Vietnamese pick up a cue. Every night, millions of shots are taken. And almost all of it vanishes from human memory the moment the ball stops. This is what separates billiards from football. In football, even if you play on a bad pitch in a rural district, the result is recorded by someone: the score, the scorers, the line-ups. In billiards, if you play in a sidewalk café at two in the morning and you produce a ten-point run — a pattern any professional would nod at — that run does not exist in any data system in the world. There is a sentence I wrote in a draft I never published, and I still keep it in an old notebook: too much emotion, too little data. I wrote it on a July night, after a young editor sent me a rejection letter with exactly those words. I was angry then. Now I think it is the most accurate description of Vietnamese billiards I have ever heard. To understand why this matters, you need to understand the language three-cushion billiards speaks. This is not a directly confrontational sport. Two players do not fight over a ball. They share a single table, take turns at the cue, and each tries to score as many points as possible during their turn. The target of a match is usually a round number — forty, fifty points — and whoever reaches it first wins. Which means the entire match reduces to two quantities: the points you score, and the innings you need to score them. From that comes the most important metric in the sport, the one Vietnamese players simply call "the average": total points divided by innings. A player averaging 1.5 means that every time he bends down, he brings back one and a half points. A player averaging 2.0 belongs to a completely different class. It is a strangely beautiful metric, because it does not measure technique, or power, or speed. It measures patience. A high-average player is not the one who plays the most beautiful shots, but the one who makes the fewest mistakes on the most ordinary shots. In my entire career of watching, I have never seen a sport where the ordinary is so expensive. Beside the average lies the run: consecutive points within a single inning. This is the quantity audiences love, because it produces excitement. A ten-point run makes the stands rise. A fifteen-point run makes people remember a player's name. And in a match to fifty points, a fifteen-point run is a psychological earthquake. But here is what very few outside the sport realise: high runs do not equal winning. I have watched plenty of matches where the winner had the single highest run, while the loser finished with the better average. A run is a peak. The average is the whole mountain range. And in this sport, the range decides who is still standing at the end. If you want to see this clearly, look at Tran Quyet Chien's record in recent years. He is not the type of player who produces long runs like a storm. He is the type who holds a rhythm. The tournaments where he goes deep are usually the ones where his average rises only slightly — but rises steadily across the whole week. That is the kind of data that makes no noise, and it is precisely what creates championships. On the other side, Bao Phuong Vinh represents a different generation. Younger, faster at the cue, and more willing to accept risk in situations where the previous generation would choose the safe option. In a sport with a fixed target and no time limit, choosing risk or safety is not a technical decision. It is a philosophical one. The safe player stretches the match out. The risky player compresses it. And in tournaments with dense schedules, both strategies have a price. This is why tournament format becomes part of the data story, not just a technical detail. A knockout event with matches to forty points creates an entirely different environment from a round-robin where every match runs to fifty. In short formats, a player can win on two lucky runs. In long formats, luck is diluted to almost nothing, and the average is exposed. In Vietnam, most domestic tournaments still lean toward short formats. There are practical reasons: table rental costs, organising costs, and the entertainment needs of audiences. A three-cushion match lasting three hours is a great match for people inside the sport, but a test of patience for television viewers. So organisers compress it. And by compressing it, they unintentionally create a playing field where sudden shots are rewarded more than stable systems. I look at an ordinary billiard hall in Nha Trang and see exactly that structure, only at a smaller scale. A match between two friends usually runs to twenty or thirty points. It lasts about forty minutes. In those forty minutes there may be a six-point run — and there may also be thirty innings that produce only two points. The winner is sometimes the luckier player, not the better one. This is where I have to talk about what I call the ritual of silence. In three-cushion billiards, the time between one player's innings is usually longer than the time he actually holds the cue. The player sits down, wipes the tip with a cloth, takes a sip of water, watches his opponent. During that time the match does not stand still. It is happening inside his head: reading the position, recalling what the opponent has done, calculating how many points he still needs, and weighing whether to change the tempo. Nobody films that silence. No statistics table records it. And that is exactly why I believe the match truly begins from the moment nobody is touching the balls. The resting chair is where the most important decisions happen, and also where they are most forgotten. There are points that never appear on the scoreboard; they live in the breathing of the hall. I have sat in Vietnamese billiard arenas where hundreds of people held their breath as a player prepared the third contact of a difficult pattern. When the ball was struck correctly, the applause broke like a rainstorm. No metric measures that rainstorm. But it is real. And it affects the player in the next inning — something anyone who has competed knows, even if nobody can quantify it. So where does Vietnamese billiards data live? A small part sits in the UMB ranking system, where Vietnamese players appear with points accumulated from World Cups. Another part sits in the records of the Vietnam Billiards & Snooker Federation (VBSF), which logs the results of national tournaments. But the largest part — by far the largest part — lives in the memory of people like H., and in the notebooks of people like me. Compare this with snooker and the gap becomes obvious. Snooker has an almost complete data system: every professional match is recorded, every break is counted, every safety success rate is calculated. You can look up anyone, any match, any moment. In three-cushion billiards, even at world level, the detail of data is far lower. At Vietnam's national level, it is close to zero. This creates a fascinating paradox. When you have no data, you cannot prove anything. And when you cannot prove anything, every judgement becomes a personal opinion. In Vietnamese billiard circles, arguments about who was the best player of a generation usually end in sentiment: people remember this shot, remember that win, and forget the twenty matches in between. Collective memory has a very specific blind spot: it keeps only the moments with the highest emotion, not the moments with the highest value. A decisive shot at the forty-fifth point will be remembered forever. A safety at the twelfth point — the shot that actually created the chance for the decisive one — is forgotten before the match ends. I do not write about the scores. I write about what the scores hide. And in billiards, what is hidden most is the innings that produced no points but left the opponent unable to strike back. When you watch a professional three-cushion match, you usually see about thirty per cent of the game. The other seventy per cent lives in the moments spent pushing balls into corners, leaving distant positions, accepting a bad shot in order not to hand the opponent a good one. These decisions are not glamorous. They do not appear in viral clips. But they decide who wins. The problem is that almost no data exists about them. Nobody counts how often a player leaves a hostile position. Nobody measures the success rate of safe shots in Vietnamese three-cushion billiards. So tactical debate in the sport usually runs on intuition, and intuition cannot be verified. Here I want to name another paradox: the wider the movement, the shallower the data. It sounds absurd, but it is true. A country with few tables and few players finds it easier to build a data system, because there are fewer events to record. A country with tens of thousands of tables and hundreds of thousands of players turns recording into an infrastructure problem, not a technical one. South Korea is a useful comparison. The arrival of the professional PBA circuit turned three-cushion billiards in Korea into an industry with contracts, television and data. The world's leading players from Belgium, the Netherlands and Sweden compete there regularly. And along with that comes a statistical infrastructure any analyst can access. Vietnam does not yet have an equivalent system. But Vietnam has something not every country has: a generation of players who have proven themselves at world level, and a billiards culture that grew out of everyday life rather than sports academies. In Vietnam, a child can start playing in the family café and fifteen years later stand at a world championship. That does not happen in many places. But precisely because it starts in a café, it lacks what sports academies have: tracking, recording, evaluation. Nobody recorded that a twelve-year-old in Binh Duong had an average rising steadily month by month. Nobody noticed that a thirty-year-old in Can Tho had an unusually high success rate on cushion-angle shots. Those signals exist. They are simply not seen. This is the point where I want to spend the rest of this piece on the opposite idea — what I call the blind spot of collective memory. Over forty years of watching billiards, I have repeatedly seen one phenomenon. A young player appears, impresses with two or three big matches, then disappears from the lights within three years. Fans call it "loss of form", "lack of nerve", or simply "no luck". But when I dig deeper, most of these cases share a cause that has nothing to do with psychology: they had no support system to sustain progress. A professional in Europe has a coach, a video analyst, a designed training schedule. A Vietnamese player usually has a cue, a phone, and a group of friends to play with. He improves by playing more. But playing more does not mean improving faster, because nobody points out the systemic flaw in his game. This is where data should do its work. If you have numbers on which group of shots costs a player the most points, you can design drills to fix it. If you have numbers on whether a player performs better when trailing or leading, you can adjust psychological strategy. Without data, all of this becomes guesswork. Of course, there is a counter-argument, and I think it deserves serious consideration. Three-cushion billiards is a sport of feel. The greatest players in history all speak of something hard to describe: the feel of the table, the feel of the cushion's bounce, the feel of the ball as it leaves the tip. None of that lives in a spreadsheet. If you turn billiards into a purely data-driven sport, you can ruin it. You can produce players who play too safe, avoid risk, and play to protect their metrics rather than to win. That has happened in other sports, and it has produced dull seasons. So where is the balance? In my view, it lies in one very specific place: data used to understand, not to constrain. You measure to know where you are, to know where you need to go — not to prove you are better than someone. The best players understand their own numbers clearly while keeping their freedom when they bend down to the table. In Vietnam, I am not worried that data will kill that freedom. I am worried about the opposite: the absence of data is wasting the talent this country has. Go back to the billiard hall in Nha Trang. In the four hours I sat there, seven people played. Two of them had technique at a level that could compete in a national tournament if they were trained properly. Neither of them knows that, because nobody told them, and no data shows them where they stand against the field. This is a waste that could be measured if we had the tools to measure it. But we do not have the tools, so we do not see the waste. And what is unseen does not have to be solved. There is one more thing I want to raise, though it is more sensitive: the lack of data transparency and the problem of betting in billiards are connected in a certain way. When the result of a match is not recorded in full detail, checking a suspicion becomes far harder. In sports with complete data systems, an abnormal win rate can be detected automatically. In grassroots billiards, no system does that work. I have no evidence about any specific case, and I will not speculate about individuals. But structurally, this is a weakness anyone who cares about the sustainable growth of this sport should recognise. And here I must admit something about myself. For a long time I believed that writing about billiards meant recording clear moments, without numbers. I was rejected by an editor for exactly that, and I spent two weeks unable to write, shutting myself in a room to rewatch matches alongside passing data. During that time I realised something: if I did not use data, I would be left behind. Not because data is truer than emotion, but because data is the common language of the age. A good piece about billiards has to speak both languages. I began placing statistics beside imagery, like setting a stone beside a river. In every piece I gave at least one paragraph to cold metrics before entering the emotional section. I never skip data, because I understand it is the evidence for the emotions I want to describe. But another lesson came later. In 2026, when the pandemic closed stadiums and arenas around the world, I went through a crisis of faith. During 398 days without live sport, I stayed home, re-read old recordings, and happened upon data of my own from seventeen years earlier: figures on successful passes by a Khanh Hoa football club in an old season. I took a pencil, connected the data points on a sheet of paper, and realised they formed a long line that seemed to dance. That was when I understood what I had always felt but never expressed: data is not only evidence. Data, placed correctly, is a form of emotion. I wrote a two-thousand-word piece about passes as a sacred language and posted it on my personal page. Nobody shared it. But I cried, because I had found a reason to keep writing. Since then I keep one habit: after every match I follow, I write a draft twice as long as the published piece, shared with nobody. In those drafts I record everything: statistics, silences, feelings, even meaningless details like the temperature of the arena. That draft is where I keep the largest part of the match — the part nobody else sees. And in every draft, I always write one line about the players in the sidewalk halls, the ones who will never appear in any data system. I write about them because I believe a sport cannot grow sustainably if it remembers only the winners. Back to H.'s nine points that night. Three weeks later I met him again in the same hall. I asked if he remembered that match. He thought for a moment and said: "Of course. I practised that pattern for three months before I could play it." Three months. That is a metric. It is a number that can be measured, recorded, compared. And it tells us more than any ranking: that progress in this sport does not come from flashes of brilliance, but from months of repeating a single shot until it becomes part of the body. If there were a system recording those months — for hundreds of thousands of players across Vietnam — we would have a map of this country's talent that nobody currently possesses. We would know where talent grows, how it grows, and what it needs to mature. We would stop wasting it. But I also understand that building such a system is not something an individual can do. It needs a federation, clubs, tournament organisers. And above all, it needs a change in how we see this sport: from a leisure pastime into a sport that can be studied. While waiting for that, I still sit in billiard halls at two in the morning, taking notes by hand, telling myself that one person recording a match is still better than nobody recording anything. There is a question I have never answered, and perhaps never will: if H. had scored ten points that night instead of nine, would it have changed his life? I do not know. But I know that if nobody recorded those nine points, the answer is certainly no. And perhaps that is all I need to keep writing: not to find the answer, but to keep the question alive. Because a sport truly dies only when nobody remembers how it was once played.
