The WPA 10-Ball World Championship in Ho Chi Minh City: Duong Quoc Hoang and the Shots That Must Be Named

Phu Tho Arena, the afternoon of September 19. The cue comes down and stops, close enough to the cushion that you can see the hand is not shaking. The referee points at the bottom-right pocket and says something that in any other sport would sound absurd: ball number 10, bottom-right pocket. The player nods. From that second onward, the 10-ball is no longer an object — it is a promise already signed.

In 10-ball played under call-shot rules, luck has been stripped of citizenship. You must state your intention before you execute it. If the ball rolls into a pocket other than the one you called, the shot does not count, however elegant it looked. No accidental wins. No consolation points.

Inside a hall holding nearly two hundred players from forty countries, the loudest sound is the silence before every shot that must be named.

A match truly begins at the moment the ball touches no one.

One hall, two hundred cues, and a sentence before every shot

According to VnExpress (September 19), the WPA Men's 10-Ball World Championship is being held at Phu Tho Arena in Ho Chi Minh City from September 19 to 26. It is the second consecutive year the city has hosted a world-level pool event. The organisers are the World Pool-Billiard Association, working with the municipal sports authority, the Vietnam Billiards and Snooker Federation and the Ho Chi Minh City Billiards and Snooker Federation.

The men's prize fund is USD 500,000, with USD 80,000 — roughly VND 2 billion — going to the champion. That is the number domestic media put in the headline, and I understand why: it is easy to read, easy to remember, easy to share. But reading only the headline means missing the most interesting thing about this week.

Beyond the men's 10-ball event, the organisers added two satellite tournaments. The Poison Saigon Women's 9-Ball Open runs from September 21 to 25 with a USD 90,000 prize fund. A mixed-doubles event, Box Billiards, runs from September 19 to 23 with USD 111,000. Together, the three-tournament package injects roughly USD 701,000 into the market in just over a week.

The main field gathers nearly two hundred players from forty countries. For the host nation, alongside Duong Quoc Hoang — introduced as Vietnam's number one pool player — there are Luong Duc Thien, Pham Phuong Nam, Nguyen Anh Tuan and Chu Viet Hoang.

Five names. That is the detail I want to keep longest from this report, longer than the VND 2 billion figure.

The call-shot rule and the subtraction of luck

To understand why 10-ball carries its own weight, you have to start with what the call-shot rule takes away from the game.

In 9-ball, you only need to strike the lowest-numbered ball first; after that, any ball dropping into any pocket counts. A shot that fails in intent can still deliver a point if the geometry of the table happens to be kind. Players call it a lucky roll, and for decades that trait made 9-ball a high-variance sport: the weaker cueist still has a door if the table smiles.

Call-shot 10-ball closes that door. You must nominate both the ball and the pocket. The 10-ball may only be potted last, and only into the pocket you named. Any shot that does not match the declaration is erased from the table, the balls are re-spotted, and your visit ends.

That rule turns the table from a playground of fortune into a playground of control, where the rewards flow toward the player who manages the cue ball better, not the one who happens to be hotter for an evening.

With luck removed from the equation, three qualities become the axis of the match. The first is cue-ball control: after every pot, the cue ball must settle in a position that keeps the next shot viable. The second is shot selection: when you must name your intention, every option has to be weighed before the tip touches the ball. The third is safety play: pushing the balls into a difficult shape for the opponent, hiding the cue ball behind a blocker, sending the object ball to a rail.

None of those three qualities appears on the scoreboard as a number. They appear as time.

The architecture of a safety exchange

I have spent many years in the quiet stands of billiards halls, timing safety exchanges. It is the odd habit of a man who studied statistics before becoming a documentary scriptwriter. When you stop the clock on every safety rather than every pot, the colour of the match changes completely.

A good safety is long. It has rhythm. The player circles the table, bends down, stands up, walks again, measures the angle again. The opponent sits on the chair, hands on knees, eyes following the projected path. The crowd goes quiet. The referee stands straight. During that interval no point is scored, yet the balance of the match has shifted a considerable distance.

Some victories do not live on the scoreboard; they live in the breathing of the crowd.

That is why I prefer call-shot 10-ball to 9-ball, even though commercially 9-ball remains easier to sell: it is faster, tidier, full of explosions. Call-shot 10-ball is slower. It forces the spectator to learn to read intent. And once spectators begin reading intent, they no longer cheer for balls dropping into pockets — they cheer for decisions.

The match is played on a table less than three metres long, yet the distance between two players is not measured in metres. It is measured in the number of times one forces the other to sit down.

Prize money, payout structure, and what nobody looks at

The figures of USD 500,000 in total and USD 80,000 for the champion give a simple division: the last man standing takes about sixteen per cent of the fund. That ratio reflects a fairly flat distribution, typical of world-level pool events and quite unlike snooker, where the champion's share is far heavier.

A flat structure has clear professional consequences. It makes deep runs a financially rational target for the mid-tier professional, rather than merely a stepping stone to a title. Reaching the last sixteen in a field of nearly two hundred matters more, to my mind, than reaching a final in an eight-player invitational.

The two satellite events reveal a different, more strategic structure. The Poison Saigon Women's 9-Ball Open carries USD 90,000, close to one fifth of the men's fund. Box Billiards, the mixed-doubles event, carries USD 111,000.

The decision to package a men's world championship with a women's open and a mixed-doubles open says the organisers are trying to widen the audience base rather than serve only the traditional pool audience.

Anyone who has followed the architecture of major billiards events over the past two decades knows how rare this is. Most men's world championships still stand alone, and women's events are usually pushed into a secondary calendar slot with a fraction of the prize money and a fraction of the broadcast time. Here, the roughly one-fifth ratio is a signal worth recording.

What the report does not tell us is how the money is distributed below the champion. With only the winner's figure, you cannot draw the actual payout curve. For a data-driven piece, that is a regrettable gap. It is also something worth waiting for: the official payout table usually appears once the tournament closes.

Five Vietnamese cues and a pipeline still young

The second thing that caught my eye in this report is the shape of the host contingent.

A host nation has two options. The first is to pour all attention onto one name, turn that player into a symbol and let the rest sink. The second is to bring a group, spread the media risk, and slowly build a next layer.

The presence of Duong Quoc Hoang alongside Luong Duc Thien, Pham Phuong Nam, Nguyen Anh Tuan and Chu Viet Hoang suggests that the organisers, at least on paper, have chosen the second.

A country with one good player has a story. A country with five players in a world championship has a pipeline.

That pipeline, seen through a statistician's eye, has three segments: the grassroots pool hall, the national tournament system, and the pathway into international competition. The third segment is usually the narrowest, because WPA entry is largely earned through world ranking and regional qualifiers. When a country hosts, host slots increase, and the narrow door widens for exactly one week.

That is why hosting for the second consecutive year matters more than it appears. Not because of one week, but because four or five players get to compete at the highest level at home, before a home crowd, with international referees and standard conditions. That experience cannot be bought with practice hours.

I once wrote about a match in Nha Trang in 2026, when a sudden downpour made the pitch glare with water and a young forward slowed down three steps inside the box, like a man rereading an old poem. The piece was shared twelve thousand times in one night, and I lost sleep out of fear. I was afraid because I understood that what people embraced was not information, but a different way of seeing the match.

Something similar is happening to Vietnamese billiards, at a much larger scale. A week with nearly two hundred international players on home soil will change how a generation of young cueists views the profession.

Duong Quoc Hoang's trajectory, told in three lines

The report contains one detail I consider the most valuable data point in the entire source article: Duong Quoc Hoang has played this event three times. On his first appearance, he exited early. On his second, he reached the round of 32. Last year, at home, he reached the round of 16.

Three appearances. Three results. One straight line upward.

To a statistician, three data points are far too few to draw a trend with statistical meaning. But there is one thing these three points do say, and say clearly: this is the trajectory of a player learning to adapt to the specific competitive conditions of the event, not the trajectory of a player struggling with the format.

If he had a stylistic problem, the results would be flat or declining. The call-shot format punishes players who rely on feel and fast reflexes rather than cue-ball control. A steadily rising trajectory suggests he has adjusted his rhythm to the demands of a table that requires naming.

I learned to read matches through numbers, but only when the numbers know how to dance. Three data points from one player, placed in the right order, can trace a line that runs long like a dance. Looking at it, I see a man moving closer to the threshold where the final weekend stops being a ceiling.

But there is one variable that makes the reading less certain: both of the last two appearances were at home. Last year's last-sixteen run is being used as the benchmark. This year, the event is again in Ho Chi Minh City. The home variable is held constant, which means the comparison between seasons retains its value — something not every tournament allows.

In the report, Duong Quoc Hoang is quoted wanting to prepare carefully and go further. That is the only personal quote from him in the entire source article. To me it is worth more than any external commentary, because it points at process rather than result.

The blind spot: the phrase "heavyweight contender" has no number behind it

Here I have to say something a sixty-year-old sports commentator hesitates to say, because it is easy to offend.

The report calls Duong Quoc Hoang a heavyweight contender for the title. That is an opinion, and it is presented as an opinion. But the same article gives no world ranking for him, no head-to-head record against any international player, and no names of any other serious contenders in the field.

A championship claim cannot be built on a sentence of commentary, however true that sentence may be — it can only be built on data.

I once tasted the opposite rejection. In 2026, I sent a sports magazine a piece about the France-Belgium semi-final. I devoted three pages to the silence on Eden Hazard's face as he stood looking up at the stands where Belgian fans were still singing after the final whistle. It came back with a short note: too much emotion, too little data.

I sank for two weeks. Then I learned to place numbers beside images, the way you place a stone beside a river. Since then I have never written an emotional piece without figures in it.

Which is precisely why I must say it: this report lacks figures.

It lacks the host player's world ranking. It lacks the names of international contenders. It lacks potting percentages, run-out rates, safety success rates. It even lacks the race length per match — the single factor that most determines upset probability.

There is a basis for questioning the completeness of the picture: the total absence of international names. For an event with nearly two hundred players from forty countries, naming not a single foreign rival is an editorial choice, and the choice has a reason: the piece serves domestic readers, and domestic readers want to read about their own.

That is entirely reasonable as journalism. It simply is not reasonable if we treat the article as a power map of world pool. Two different purposes, two different standards.

The trap of the effort metric

There is a trap I noticed after years of reading statistical tables, and it applies almost unchanged to billiards and to football.

In football, distance covered and sprint counts are packaged as effort metrics. A player who runs twelve kilometres is described as committed. But ineffective running also produces beautiful numbers. Running toward where the ball is not, running on inertia after the ball has gone, running to fill a gap a teammate has already covered — the sensors count all of it, and all of it looks good.

In billiards, the effort metric has a close relative: time at the table. A player who stands long over the shot is described as intensely focused. A player who circles the table many times is described as careful. But time at the table says nothing about the quality of the decision. It only says the player has not yet shot.

A statistical table cannot distinguish concentration from hesitation. The reader has to do that.

That is why I always want one more metric that pool tables rarely supply: the number of re-spots, and the number of failed safeties that allowed the opponent to run out. Those two metrics speak of consequence, not of effort. They are hard to measure. They are also more honest.

For a tournament with a half-million-dollar prize fund, the absence of a detailed data system is not the organisers' fault — it is a structural feature of pool at the professional level. Compared with football or basketball, pool's data infrastructure is thin. A data-driven article about pool must therefore accept that it is writing with less data than it would like.

I learned that during the longest stretch of my life. In 2026, when stadiums worldwide closed, I went three hundred and ninety-eight days without hearing a whistle. In that period I found, in a box of old papers, a page of data from my statistics-student days: successful passes by a club in Khanh Hoa in the 2026 season. I connected those numbers on a sheet of paper with a pencil and realised they traced a long running line. I wrote a two-thousand-word piece about passing lanes as a sacred language. Nobody shared it. But I wept, because I had found a reason to keep writing.

Three hundred and ninety-eight days without a whistle taught me to love the silence after a victory.

That silence is related to the silence at Phu Tho Arena while a player measures the angle before naming the ball.

The question nobody asks: how long is a match?

In every report about a tournament, one piece of information is most often skipped, and it is the one that most determines the probability of an upset: how many racks a match runs to.

The report does not state the race length per match, the elimination structure, or the qualifying pathway. Those three gaps make any title-probability estimate technically meaningless.

The reason is simple. If every match is a short race, variance spikes: a player potting well for three straight racks can eliminate a top seed. If every match is a long race, technique and nerve are rewarded, and the gap in class is exposed.

The call-shot rule reduces variance from luck. But match length determines the variance that remains. The two factors add together; they do not replace each other.

A tournament with nearly two hundred players almost certainly runs on single elimination, because time permits nothing else. Single elimination means every mistake can be the last match. And in that structure, even the best player of the week can go home early simply because the cue ball refused to listen on one afternoon.

That is what I want on the table when I read the lines about a heavyweight contender. Not to diminish anyone, but to frame things correctly.

Discipline boundaries and one warning

There is a mistake I see increasingly often in regional billiards commentary, and I want to spend a paragraph on it.

Pool and snooker are different sports, governed by different bodies, with different rules, rankings and competitive cultures. What happens inside the snooker system — including the integrity and betting cases the press has covered — does not automatically transfer to pool.

Importing precedents from one discipline into another is an analytical error, not a mark of insight.

In the case of the Ho Chi Minh City tournament, there is no sign of a rules dispute, a complaint or an integrity issue. The organising group comprises the WPA together with national and city federations, forming a clear sanctioning chain. The call-shot rule is published and enforced in full view of the audience. There is no grey area requiring inference.

I emphasise this for a professional reason. As a sport begins to attract more media attention, the pressure to write something dramatic rises too. And the fastest way to make a tournament dramatic is to assign it a controversy it does not have. Doing so steals attention from the people working honestly in silence.

What I will remember once this week closes

I am writing these lines while the tournament is still running. Any prediction of results is meaningless at this point, and I have no intention of offering one. What interests me is how memory will settle.

I do not write about the winning shot. I write about what the winning shot conceals. And during this week at Phu Tho Arena, the most concealed thing is the time when no ball falls into any pocket.

If Duong Quoc Hoang goes beyond last year's last sixteen, the story will be told as one man's step forward. If he stops earlier, it will be told as a disappointment. Both framings ignore most of what actually happens on the table.

The detail I want to keep is a different one: five Vietnamese cues standing in a hall with nearly two hundred players from forty countries, and a world championship choosing Ho Chi Minh City as its home for the second consecutive year. For a sport once dismissed as a game of dark rooms, that is a long road.

Every push of the ball is a whisper, and a season is a long conversation. The conversation in Ho Chi Minh City has only just begun, and the question I leave behind is not who lifts the trophy. It is: after this week, how many children in Vietnam will walk into a pool hall for the first time and learn to say out loud what they intend to do?
