Inside the 10-ball Skeleton: Hoang 'Sao' and the Call-Shot Lesson at the WPA World Championship

There is a moment that anyone who has ever stood beside a billiards table remembers: the ball rolls into the pocket, the crowd applauds, and the referee shakes his head. In American pool played under call-shot rules, that shot does not count. The ball is already resting in the pocket, the collision has already echoed, but the scoreboard stands still. I have watched countless snooker matches in the era when Clive Everton still held the microphone, and I remember how he spoke of precision as a rite. But call-shot is a different species. It demands not only physical precision; it demands precision of intent. You must nominate the ball and the pocket before the cue touches the ball. This is not a matter of luck; this is a matter of whether you can control your own hand.

Numbers do not tell the whole story, but they know where the story begins. This edition of the WPA Men's 10-Ball World Championship carries a total prize fund of 500,000 US dollars, with the champion pocketing 80,000 dollars — roughly two billion Vietnamese dong in the way Vietnamese media likes its headlines. Nearly 200 players from 40 countries. The Phu Tho Arena in Ho Chi Minh City. And among them, one name is printed on the front page: Duong Quoc Hoang, nicknamed Hoang 'Sao' — 'Star' — Vietnam's number one pool player. That is where I begin.

Before you pick a team, read what people call them. 'Sao' is not a small name. In a billiards culture where players are often called by their hometown or their trade, attaching the word 'star' to a surname carries another meaning altogether: someone has decided to turn him into a symbol before he has proven it. And that is the point I want you to hold for this entire piece — a symbol is different from a champion. The distance between those two things is where my analysis starts.

This is a piece written for the British audience. I work in Liverpool, reporting on billiards for the English-speaking market, but I still keep the Vietnamese–British hybrid in my pocket as a weapon not everyone possesses. And I will not soften my language: this is a tournament whose name most British fans do not know, yet it contains one of the most compelling stories in global billiards this decade.

Context: a tournament of two layers

To tell it honestly, I have to split this tournament into two layers of history. The first layer is the event that gave birth to it. The WPA — World Pool-Billiard Association — is the governing body for pool disciplines at world level, entirely distinct from the WPBSA of snooker. This is a point I want to pause on, because there is a large trap in sports journalism: confusing snooker with pool. The two use a cue, use balls, use a table with pockets, but they are two ecosystems of rules, two ranking systems and two governing bodies. If you plan to write about billiards and you confuse them, you are writing wrong from the root.

The WPA Men's 10-Ball World Championship is the elite stage for the discipline of 10-ball — a branch of American pool. In 10-ball, the table carries ten balls numbered 1 to 10, and you must strike the lowest-numbered ball first, then pot the 10-ball last. This is not snooker, nor is it Chinese 8-ball. This is pool. And this is the second consecutive year the event has been staged in Ho Chi Minh City — a signal far more important than many assume.

This event is a festival of three tiers: the WPA Men's 10-Ball World Championship, the Poison Saigon Women's 9-Ball Open, and the Box Billiards mixed-doubles open. Three events, with combined prizes of roughly 701,000 US dollars. It sounds like an ordinary sporting figure, but to me it is an indicator of market psychology.

Now I want you to temporarily forget the number and look at the organisational skeleton. The co-organisers include the WPA, the national billiards federation, the city billiards federation, and the municipal sports department. That is a textbook public–private sanctioning chain, exactly what you expect for a world championship. And it says something about the market: a city with enough public funding, enough sponsors, and enough resources to hang a 700,000-dollar prize is not doing this as a one-year experiment. This is organisational.

The core: the call-shot rule is the spine of the entire story

Now we arrive at the technical part. I want you to look at the call-shot rule — call-pocket — the way you would look at the spine of a body. Everything else hangs on it. In 10-ball under this format, you must nominate the ball and the pocket into which you intend to sink it. If the ball drops into a different pocket through luck, it does not count. This is what made the name of 10-ball as against 9-ball.

Why does this matter? Because it kills the luck factor. In 9-ball — the discipline many people know because it appears more often on television — you can score with shots that are not truly intended. A ball that falls 'by accident' still counts. In the trade this is called 'slop' or 'luck'. And precisely because of this, 9-ball is a sport that explodes easily, that surprises easily, but that demands less technical completeness.

10-ball with call-shot reverses all of that. It forces you to speak before you act. It forces you to control the cue ball to the millimetre. It forces you to choose a wise shot rather than a shot that tests your luck. And it is especially severe with safety play — the defensive shot that places the opponent in a difficult position.

I once had the pleasure of comparing pressing systems in football with defensive systems in basketball. But here, I want you to see that call-shot in 10-ball is like a strict offside rule in certain tactical football versions: it punishes you for actions that feel right but are wrong in intent. You must be deliberate. And that turns this game into a sport of the head, not of the arm.

Now I want to speak of the second, deeper consequence: call-shot turns defensive tactics from a fallback option into part of the primary plan. When you know that a risky shot may not count, the safe shot becomes equal in value. This is why analysts of American pool regard 10-ball as a more 'grueling' game than 9-ball — harsher, more gruelling. And that is why the original article's line — describing 10-ball as 'one of the most grueling arenas on the planet' — is not marketing hyperbole. It has a technical basis.

I want to pause here and speak about something very few Western analysts say about Asian billiards: structural misunderstanding. When you report on billiards, there are two mistakes you can make. The first is confusing snooker with pool. The second is lumping 9-ball and 10-ball together as one discipline. Both mistakes lead to wrong expectations. And in a piece like this, where a Vietnamese player is placed at the centre, understanding the playing field correctly is the first condition for being fair to him.

Testing Hoang 'Sao's progression

So what data do we have on Duong Quoc Hoang at this very event? He has appeared three times. The first time, he exited early. The second time, he reached the round of 32. The third time — last year — he reached the round of 16, on home soil.

I want you to read those three numbers as a linear graph, not three scattered data points. Because in a sport where familiarity with the format decides much, this is the most valuable signal.

First, understand the meaning of the round of 16 in a field of nearly 200 players from 40 countries. This is not a village tournament. This is one of the harshest arenas, with call-shot rules removing luck. Reaching the top 16 means you have won several matches in a row inside a tight draw. This is a genuinely significant achievement, not an inflated one.

Second, what does the monotonic progression (early exit → R32 → R16) say about psychology and technique? It says Hoang is not shocked by the big stage. He does not stumble when he steps onto the world stage. He adapts gradually to each level of opponent, and each year he goes one step further. In billiards, that is the signature of a player accumulating experience the right way — not the kind who finishes second then falls back, but the kind who climbs a staircase.

Third, and this is the subtlest point: his top-16 finish last year came at home. This year is also at home. The 'home advantage' variable is held constant. That means if we use the round of 16 as a baseline to judge this year, we are comparing apples with apples. That is an important analytical caution, because many will say 'last year he was top 16 at home, so this year will be the same'. But the reality is harsher: climbing from the round of 16 to a final is an abyss-sized leap in professional billiards, not a small step.

I want to stress this because it matters. In call-shot 10-ball, the gap between a player who reaches the top 16 and one who reaches the semi-final is not a gap of raw talent; it is a gap of mental consistency across a long series of matches under unrelenting pressure. A player can play brilliantly for three matches then collapse in the fourth. That is the nature of this format.

And here is the point I want you to remember: I am not saying Hoang 'Sao' is a title contender. I am saying he is a player on the right trajectory. Those are two different sentences, and journalism often mixes them up.

Data gaps and the 'title contender' trap

Now we arrive at the part where I have to be blunt. The original article describes Hoang as 'Vietnam's number one player' and 'a heavyweight contender for the championship'. The first sentence is an anchored fact: he tops the Vietnamese billiards scene. The second is an opinion — and it has not been proven by data.

I want to analyse the second sentence more closely. 'Heavyweight contender for the championship' requires something the article does not provide: his world ranking. National ranking and world ranking are two different things. A player can be number one in Vietnam and still sit outside the world top 30. That does not mean he is not good; it simply means that calling him a 'title contender' based on a national title is a leap of logic.

This is where I want you to remember what I said at the beginning: 'Before you pick a team, read what people call them.' The name 'Sao' carries weight. The title 'number one in Vietnam' carries weight. But in an event with 40 countries, 'number one in Vietnam' does not automatically equate to 'title contender'. Home media tends to inflate the flag-bearing figure. That is a natural instinct, not a conspiracy. But the intelligent reader must separate the two.

I want you to compare this with a similar context in football. When a player is the number one star of a small nation, that country's press will call him 'the star of the tournament'. But when that tournament features strong teams from Europe or South America, that label becomes a semantic problem. The star of a weak team in a strong tournament is not automatically the star of the tournament. That is the logic I am applying to billiards.

And here is the interesting part: Hoang himself seems to understand it. The quote in the article shows him speaking of 'careful preparation' and 'hoping to improve'. There is no bold claim about winning. That is an important psychological signal. A player who is genuinely confident tends to speak of process, not of the final outcome.

The long-arc ecosystem: where is Vietnam heading on the world billiards map?

Let us set aside Hoang the individual for a moment. The bigger picture — and to me the more interesting one — is that Vietnam is hosting this event for the second consecutive year, and fields a cohort of five players: Duong Quoc Hoang, Luong Duc Thien, Pham Phuong Nam, Nguyen Anh Tuan, and Chu Viet Hoang.

Five names. Not just one flag-bearer. That is a pipeline signal — a system producing athletes, not just one outstanding individual.

I have spoken to many people in the Asian billiards world, and I always get the same answer: the power centres of American pool lie in the United States, the Philippines, Chinese Taipei, and parts of Europe. Vietnam is not yet in that group. But hosting a world championship two years in a row — with a total prize fund of seven hundred thousand dollars and a three-event festival — is a sign that a market is shifting from spectator to player.

And here is the point I want you to notice especially: a five-player cohort does not appear by accident. It means there is a qualifying mechanism or host slots in operation. It means there is a system behind it: training funds, domestic tournaments, billiards clubs from Hanoi to Can Tho. You cannot stage a world event two years in a row and field five players if you only have one excellent person. You must have an ecosystem.

There is a way to test this through cross-sport comparison. Think of small nations in Olympic athletics history. Jamaica did not rise in athletics solely because of Usain Bolt; Bolt was the tip of a system of schools and meets built over decades. Vietnam in billiards is at a possibly similar moment — not an aberrant individual, but a wave.

The counter-intuitive angle: what you cannot see will shape the result

Now I want to flip the issue. Suppose everything I have analysed about Vietnam is correct: a rising ecosystem, two consecutive years of hosting, five players, one man in the round of 16. There is still something I want you to look at — and it is counter-intuitive.

It is this: the very absence of information about international rivals is the largest variable of this tournament.

The original article — and this is where I must be blunt — names no international player as a title contender. No American, Philippine, or Chinese Taipei player is mentioned. That means we are building a power map from only part of the data.

Why does this matter? Because if you do not know which top Philippine players are present, you cannot know whether Hoang can reach a semi-final. If you do not know which Chinese Taipei player sits in his section, you cannot predict the round of 16. The power map of any championship is drawn by the names of the opponents, not by the name of the protagonist.

And this is why I speak of 'counter-intuitive'. Most people think the deciding factor in a player's success is individual skill. To me, the deciding factor is the draw allocation. A player who is number one in Vietnam can be eliminated in round one if he meets a former world champion in his opening match. Conversely, a lower-ranked player can reach a semi-final if the draw opens up.

In billiards, as in any knockout combat sport, your luck does not come only from your shot. It comes from whether you meet a hard opponent at the right time. And in an event of nearly 200 players, with no tight seeding, the draw factor can be larger than skill.

I have no information on the seeding mechanism of this event. Nor do I have information on the race length (the number of racks needed to win a match). Those are two big gaps. If the race is long (say race to 9 or 11), technically complete players will prevail and the arena will produce fewer surprises. If the race is short (race to 5 or 7), luck rises and weaker players have a chance to create an earthquake.

I want you to remember this as a general rule: you cannot judge a person's title chances if you do not know the competition rules. This is not pointless caution; it is necessary caution.

Prize architecture and the financial structure of the event

Now I want to discuss an aspect many Western sports journalists ignore when writing about Asian events: prize architecture. 500,000 US dollars total prize, with the champion taking 80,000. That is a ratio of roughly 16 per cent to the winner.

Compare this with the snooker World Championship, where the champion's share of the total is typically higher. This American pool event has a flatter distribution — spread more evenly from the outer rounds. This means a player who reaches the quarter-finals can still earn, whereas in snooker you must go deeper to be profitable.

What does that mean? It means the financial structure of the 10-ball World Championship encourages broader participation; more players can make a living from the game. That is a plus for the sport's development. Compare it with esports prize structures — where prizes tend to concentrate extremely on the top three teams — and 10-ball looks fairer.

But here is the interesting part: when you have a 500,000-dollar total but stage two additional events with 90,000 and 111,000 dollars, totalling about 700,000 dollars, you are running a sports festival, not just a tournament. This indicates strategic investment rather than a one-off event.

The festival model and the intersection with equipment industry

This is a point I particularly like and want you to notice. The two side events carry brand names: the 'Poison Saigon Women's 9-Ball Open' and the 'Box Billiards mixed-doubles open'. Poison is a famous cue brand. Box Billiards is another brand. The appearance of brand names in event titles is not just sponsorship; it is a commercial transmission channel.

When an equipment manufacturer puts its name on a tournament, it is not just advertising. It is building a direct bridge between its product and the end consumer. A billiards player watches the event, sees the name Poison, and goes to the shop to buy a Poison cue. That is the loop: brand → event name → viewer → shop. In the sports industry, this is a classic but effective sponsorship model.

I want to compare this with other sports. In tennis, there are ATP/WTA events carrying sponsor names such as the Rolex Masters or the MercedesCup. In billiards, this is even more common, because equipment brands are part of the culture of the sport. Billiards players do not just buy a cue; they buy an identity. They choose a cue the way a tennis player chooses a racket.

This means the investment of equipment brands in tournaments is not charity. It is directly profitable investment. And when equipment brands see Vietnam as a potential market, they will pour money in. Two consecutive years of staging the event is a sign that sponsors are seeing growth.

I also want to speak plainly about this: if Poison withdraws next year, the event will come under financial pressure. The title-sponsorship model has the advantage of recognition, but the disadvantage of dependence on a few sponsors. That is a structural risk of the whole festival model.

Cross-sport comparison: why 10-ball matters more than it appears

Now I want to take you into a part of the analysis I enjoy most: why 10-ball, though less popular than 9-ball, matters more for the future of billiards.

I have had the chance to analyse comparisons between sports with different structures. In basketball, people clearly distinguish the regular season from the playoffs. In athletics, between the 100m (sprint) and the 10,000m (endurance). Each format tests a different quality in the athlete.

Call-shot 10-ball is like a comprehensive test event for billiards. It does not only measure the ability to pot a ball; it measures the ability to think. You must control the cue ball, choose your shot, play safe when needed, and plan long-term. This is why the top players in the world often prioritise 10-ball for honour. A 9-ball title can come from a lucky week; a call-shot 10-ball title demands genuine completeness.

And this has direct meaning for Vietnam. If a billiards nation wants to be respected internationally, it must have results in 10-ball, not only in 9-ball. This is why Vietnam hosting a 10-ball World Championship is a stronger statement than merely hosting an extended 9-ball open.

I want to stress this, because I have seen many Western journalists downplay 10-ball. They say '10-ball is a harder version of 9-ball'. That is half true. The full truth is: 10-ball is a distinct discipline, with its own philosophy, its own competition system, and the future of elite billiards may well lie in it.

The story of names: why I write about billiards by reading names

I want to tell a personal story. In 2026, when I commentated the World Cup quarter-final between France and Uruguay for a sports channel, I made a small but serious error: I called Jose Giménez — Uruguay's centre-back — 'Jimenez' three times. Viewers complained. Management reprimanded me. And I spent the following month rewatching all of Uruguay's footage to memorise the pronunciation of each player's name.

I tell this story because it shaped the way I write about billiards. When you write about Duong Quoc Hoang, you cannot carelessly call him 'Duong'. When you write about Luong Duc Thien or Pham Phuong Nam, you must spell their names correctly. A name is a sign of respect. And in billiards, where players come from many countries, pronouncing a name correctly is an act of fairness.

This is why I want to pause on the name Hoang 'Sao' for a moment. In Vietnamese, 'sao' means 'star'. Calling a player by that name carries an expectation. But is that expectation grounded? That is the question every analyst should ask themselves. And my answer, after checking the data, is: that expectation is partly grounded. He is Vietnam's number one, he reached the top 16 at home, he is on an upward trend. But none of this is sufficient to call him a 'title contender' without world ranking data.

I want you to see the difference between two kinds of sentence: 'He is Vietnam's number one player' (fact) and 'He is a title contender' (opinion). Both may be true, but they require different levels of evidence. And good journalism must know the difference.

On the call-shot rule and the psychology of precision

I want to devote a section to speaking in depth about the call-shot rule — not in its technical aspect, but in its psychological aspect.

When you must name the ball and pocket before striking, you are committing yourself to an action. This is a form of contract with yourself. In sports psychology, committing in advance to an outcome reduces flexibility in handling but increases accountability. You cannot say 'I did not intend it' when the ball drops into the wrong pocket. You already called it.

This creates a different kind of mental pressure. In 9-ball, you can strike without calling, and if lucky, you win a rack. In call-shot 10-ball, you must be responsible for every shot. There is no room for rationalisation.

I once said to a friend who coaches billiards in Liverpool: 'Call-shot is like having to declare in advance which corner you will score into.' He laughed and said: 'Right, and if you cannot do it, you are a braggart.' That is the truth. Call-shot eliminates the possibility of bragging. It forces you to be real.

For Hoang 'Sao', this is a psychological test. He has played call-shot 10-ball at least three times on the world stage. He has improved in that format. That means he is not afraid of the format; he adapts to it. And in sport, adaptation is a more important sign than raw talent.

The Vietnamese–British cultural intersection as an analytical lens

I write from Liverpool, but I see billiards through Vietnamese eyes. This is not sentimentality; it is an analytical advantage.

When I watch a Vietnamese player compete in front of a Vietnamese crowd, I see what many British journalists do not: the pressure of community expectation. In England, a player competing in front of a home crowd also feels pressure, but it is different in nature. In Vietnam, a player who stands as the number one of a nation carries an entire community on his shoulders. He is not just playing for himself; he is playing for the pride of a rising billiards culture.

That is something I think international analysts should note. When you assess a player from a nation that is developing in that sport, you must factor in the 'burden of representation'. It can be a positive motivation, but it can also be a psychological weight.

I do not know how Hoang 'Sao' feels when he steps into the Phu Tho Arena. I only know one thing from my own experience: when you are the first, when you are 'number one', every shot you take weighs more than usual. That can be an advantage, but it can also be a disadvantage. And no one can be certain which.

Beyond the table: market, audience, and the future

Let us return to the economic picture of the tournament. A total prize of 701,000 dollars across three events in one festival is not a small figure but not a giant one in the sports industry. The snooker World Championship has a total prize of millions of pounds. The tennis Grand Slams have total prizes of tens of millions of dollars.

But billiards does not need to compete with tennis or snooker at that level. Billiards has its own niche market. And within that niche, a world championship with a 500,000-dollar total prize in Southeast Asia is an important signal.

What does that mean strategically? It means the WPA is looking at Asia as a key growth market. While the traditional markets of American pool — the United States, the Philippines, Chinese Taipei — are saturated, Southeast Asia is a rising region. Vietnam, with two consecutive years of hosting, is placing itself at the centre of that wave.

I want to compare this with the esports story. When esports began to grow in Asia — South Korea, China — international tournaments followed the market. The same is happening with billiards. Tournaments will go where the audience is, and the audience goes where the ecosystem is.

Signals to track

I want to close my analysis with a list of signals to track — not a summary list, but an observation list.

First, Hoang 'Sao's actual result. If he reaches the round of 16 or better, the 'title contender' narrative will be strengthened. If he exits early, the story will change direction. This is the simplest but most important signal.

Second, confirmation of a third year of hosting. If the WPA and the Vietnamese billiards federation announce continuation next year, Vietnam will be confirmed as a regional billiards hub. This matters more than any individual's result.

Third, the composition of international rivals. If more top world players take part next year, the event's pull will grow. If not, the event may be regarded as a regional event rather than a genuine world championship.

Fourth, the presence of sponsors. If Poison and Box Billiards continue to title the side events, the commercial chain is working. If they withdraw, that is a warning.

Fifth, the personal contracts of Vietnamese players. If Hoang 'Sao' signs an equipment sponsorship deal, that is an indicator of his personal commercial value — and of the maturity of the Vietnamese billiards market.

The contrarian angle

I want to finish with a view that may provoke. There is a popular belief that if a country hosts a world championship, that country is on the path to becoming a power in that sport. I am not sure that is true.

Hosting a tournament and winning a tournament are two different things. Qatar hosted the 2026 World Cup, but Qatar is not a football power. China hosts many snooker events, but Chinese players only began to dominate in recent years. Hosting gives you infrastructure, not talent.

So the real question for Vietnam is not 'Can Vietnam host a world championship?' — the answer is yes. The real question is: 'Can Vietnam produce a world champion?' And the answer to that is not yet available.

That is why I say that a call-shot 10-ball title is a more comprehensive test. It tests the ability to think, the ability to withstand pressure, the ability to control emotion across many days. A player can win a 9-ball title through skill and luck. To win a call-shot 10-ball title, you need something deeper: tactical maturity.

Final judgement

The thicker the data file, the more the story must be told with human ears, not machine eyes. And in this case, the data file is thin — we have three appearances, a clear progression, a national title, and a home arena. We do not have a world ranking, opponent names, race length, or draw structure.

Because the data is thin, I must tell the story with what we have. And what we have is a story of progress. Duong Quoc Hoang is not a proven title contender. He is a player rising inside a rising billiards nation. That is a real story, and it is more compelling than a painted one.

When the tournament begins at the Phu Tho Arena, I will sit in Liverpool and follow it on a screen. I will not cheer for a victory; I will cheer for a process. And I think this is the right way to cover sport: you follow not only the winner, but the journey of a sport finding its footing.

To the British readers of this piece: remember the name Duong Quoc Hoang. Not because he will win this week — but because he represents a wave you will hear more of in the coming decade. Billiards is moving east. And Vietnam is getting ready.

A major event does not end when the whistle sounds; it begins when the lights flicker out. The WPA 10-Ball World Championship will end, but the story of whether Vietnam can become a world billiards power will continue. That is not the story of a tournament; that is the story of a decade.
