One Word, Six Rulebooks: The Missing Foundation of Vietnamese Billiards Analysis

One Word, Six Rulebooks

Eleven at night in a billiards hall on Nguyen Thien Thuat Street, Nha Trang. Three men sit in front of the same screen, shout the same word — foul — and are wrong in three different ways. The first says the cue ball struck the object balls in the wrong order. The second says the shot did not call ball and pocket. The third says the cue ball did not touch three cushions.

The three of them are not arguing about billiards. They are arguing about three different sports while the screen shows one match.

I sat at the next table, opened my notebook, and wrote those three sentences down. That was the night I understood something nearly twenty years in the trade had never forced me to write as a sentence: the foundational problem of Vietnamese billiards is not technique, not money, not broadcast time. It is that we use one word for six sports.

The word is billiards. The six sports are snooker, pool 9-ball, American 8-ball, Chinese 8-ball (heyball), carom three-cushion, and Russian pyramid.

They share no rulebook. They share no technical base. They share no tournament structure. They share no commercial ecosystem. A carom table has no pockets. A pyramid table uses larger balls and tighter pockets. The break shot is decisive in 9-ball and nearly meaningless in snooker. The called ball-and-pocket convention exists in 8-ball and does not exist in carom. In snooker, we count centuries and 147s. In carom, we count moyenne and runs. In 9-ball, we count break-and-run rates.

Any claim about billiards that does not name the discipline is an unfinished claim. I wrote that line on the cover of my notebook that night in Nha Trang, and it has underpinned everything I have done with billiards since.

Why This, Why Now

I once made exactly this mistake on live television, in another sport. In July 2026, before the France-Belgium World Cup semi-final, I stated that Belgium would press high in a 4-3-3. They dropped thirty-five metres deep, ceded the initiative, and lost 0-1. Afterwards I re-watched all ninety minutes, redrew twelve transition sequences, and found the gap between Belgiums midfield and defensive lines was twenty-five metres wide.

The lesson was not stop predicting. The lesson was that every claim must be anchored to a specific, measurable, video-verifiable structure. When I moved to covering billiards for the Vietnamese market, I met the same problem in a harder form.

In football, even when wrong, I had a shared frame: a 105-metre pitch, eleven players, a round ball, FIFA laws. In billiards, I have no shared frame. Billiards is not a sport. It is a category.

And here is the timing argument. The Vietnamese billiards market is expanding faster than its analytical infrastructure. More halls, more amateur events, more streamed matches, more Vietnamese cueists competing abroad. But the number of articles that can answer one simple question — which rule set, which format, how much does this actually matter — has not grown in step.

That gap does no immediate damage. It accumulates. Every time a report files a carom player and a pool player under the same label, Vietnamese billiards star, we add another layer of blur to the foundation. A decade from now, anyone trying to write a serious history of Vietnamese billiards will have to peel those layers back one by one.

Before analysing a break shot, tell me where the cue ball is being controlled. That sounds technical. It is a foundational question. In 9-ball the break decides the entire rack. In carom there is no break at all.

Six Disciplines, and the Cost of Merging Them

Snooker

Fifteen reds, six colours, one cue ball, a twelve-foot table. The units of measurement are the century and the 147. Snooker has the most stratified tournament structure of any billiards discipline: the two-year WST ranking system, the Triple Crown of World Championship, UK Championship and Masters, plus ranking and invitational events.

Its technical base is cue-ball position management in tight space and a strong preference for safety play. This has no equivalent at comparable intensity in 9-ball, where safety still has to leave a position that can be attacked with a jump or a bank.

Pool 9-ball

Nine object balls, the nine-ball decisive. Races are short — to seven, nine, or eleven — which opens far more upset room than snooker. The break is a trained technique with its own metric: break-and-run rate. A player with a high break-and-run rate can win without ever returning to the table.

American 8-ball

Two groups, solids and stripes, and the called ball-and-pocket convention. That convention changes the nature of a shot entirely: technically beautiful shots are still fouls if they drop in the wrong pocket. No other discipline carries this variable.

Chinese 8-ball

The most confusing discipline for Vietnamese viewers. The table is close to snooker in size and pocket tightness, the rules follow the pool lineage. Commercially, it is an operator-led structure that binds events to equipment and club networks — a closed loop snooker has no direct equivalent for.

Carom three-cushion

No pockets. The cue ball must touch at least three cushions before contacting the second object ball. The metrics are moyenne and run.

This is where Vietnam holds genuine standing. Vietnamese cueists have repeatedly appeared near the top of the World Billiards Union (UMB) rankings and have won world titles in three-cushion. Ma Minh Cam, Nguyen Quoc Nguyen, Chiem Hong Thai, Nguyen Duc Anh Chien, Tran Quyet Chien, Bao Phuong Vinh — each name is a separate chapter.

This is also where the foundation cracks. Vietnamese billiards on television usually means carom three-cushion, while Vietnamese billiards in reality includes a generation of pool players competing on entirely different international circuits. Different calendars, different rankings, different income sources, and almost never on the same results sheet.

Russian pyramid

Bigger, heavier balls, tighter pockets, a different scoring system. I mention it only to fix the number: six, not three, not four.

Consequence One: Numbers Do Not Travel

A 70 percent win rate means nothing without the denominator. Seventy percent in 9-ball over races to seven is a different quantity from seventy percent in snooker over best-of-nineteen matches.

In 9-ball, variance is high. Nine balls, a decisive break, short races — a lower-ranked player retains meaningful win probability. In snooker, variance is lower: long matches, long visits, the better player wins more often and more stably. In carom, moyenne swings wildly with daily form. Three-match averages describe luck more than ability.

I have made this mistake myself. In May 2026, when European football paused, I was assigned a data-analysis series. One expected-goals figure did not match my memory of the match. I re-watched the full video and found the data had missed a shot that hit the post in the 67th minute. I built my own cross-check standard after that, and the first rule was: every number must answer the question, what was it measured on.

Applied to billiards, I establish three things before using any metric. Which discipline. Which format — how many racks, race to what. Which point in the season, because early-season and late-season form differ systematically.

In the empty season, the data is quiet, but it speaks most clearly. That is the only window in which I can check whether the numbers I used all year actually hold.

Consequence Two: Format Beats Personnel

Vietnamese fans evaluate players carefully and formats carelessly. Format is the decisive variable. In 9-ball, the gap between a race to seven and a race to eleven is larger than the gap between the world number ten and number thirty. In snooker, best-of-nineteen and best-of-thirty-five are different psychological sports. In carom, the maximum innings specified in the regulations directly determines whether a player should take risks.

Prize structure matters too, and I have not seen it analysed properly in Vietnamese. Most professional systems concentrate prize money at the top: the champion takes the largest share and the curve falls steeply. A world number forty may not cover travel; a world number five can live on prize money alone.

I give no specific figures here, because systems differ and because I do not want an unverified number in print. The shape of the distribution, however, is stable: very steep.

Consequence Three: No Power Map Without Splitting Disciplines

The world billiards power map is not one map. It is six maps stacked.

Snooker runs on the United Kingdom and China, with a still-influential 2026 generation and a rising new one. Ding Junhui opened the Chinese market, and the consequences still shape the calendar. Pool runs on the United States and Europe, with the Philippines as a striking exception — a country that produces world-class cueists far beyond its population scale. Jayson Shaw, Fedor Gorst, Joshua Filler, Albin Ouschan represent different technical schools, and their differences are differences of coaching systems, not talent.

Carom three-cushion runs on continental Europe: Belgium, the Netherlands, Turkey, Italy, Sweden. Dick Jaspers, Torbjorn Blomdahl, Frederic Caudron, Eddy Merckx defined the standard for decades. Vietnam sits in the top challenger group. That standing is standing in one discipline, not in billiards generally.

Chinese 8-ball runs on the operators who bind events to club chains and equipment manufacturers. Power sits with promoters more than federations.

Merge all six and you cannot answer a basic question: where is Vietnam. The correct answer is that Vietnam is at the top in one discipline, building foundations in a few others, and largely absent from the rest. That answer is useful. Merged into billiards, it becomes meaningless.

Consequence Four: The Monitoring Gap

I write this section with maximum caution, because it concerns compliance risk.

Match-fixing and betting risk in professional billiards is real, and international federations maintain integrity units, betting-market monitoring, and alert procedures. The Vietnamese problem is different. When a billiards report names no discipline, the reader has no way to self-assess risk. An amateur carom event and an international 9-ball event have entirely different risk structures, but in print both are a billiards match.

One principle I apply to myself: when there is no compliance signal, the correct conclusion is not clean. It is not assessed. Silence in the data is not evidence of integrity; it is silence.

Consequence Five: Player Income Ecosystems

At the top, income comes from prize money, personal sponsorships, and exhibitions or digital content. Prize money depends on the calendar; sponsorship depends on public image; content depends on consistent production — the source Vietnamese players have exploited least.

In the middle tier, income comes from coaching and amateur competition. This group carries the greatest financial pressure and receives the least attention. Competing to improve ranking and staying home to coach compete directly for time.

For newcomers, the problem is fixed cost: travel, accommodation, entry fees, equipment. In some disciplines, a season of fixed costs exceeds the potential prize money of anyone outside the top tier.

This matters analytically because a players schedule is an economic decision before it is a professional one. When a player skips an event, I do not assume form problems. I check affordability.

Consequence Six: Public Narrative and Expectation

Vietnamese-language coverage leans on four templates: prodigy, local hero, king of billiards, and comeback. Their durability differs. Prodigy lasts longest because age changes slowly. Local hero lasts moderately. King of billiards is least durable because it is tied to ranking. Comeback lives a week.

The problem is that these templates are applied without discipline labels. A carom world title and a 9-ball semi-final carry different weight, but may receive the same column inches.

I do not watch matches for entertainment; I watch to find the moment a structure begins to collapse. In billiards, structure collapses at the information layer before the technical layer. And the moment it collapses is when we attach too broad a label to too specific an event.

Consequence Seven: Industry Chain Transmission

Upstream: practice and competition infrastructure — halls, clubs, training centres, equipment. Midstream: players, events, broadcast. Downstream: sponsorship, derivatives, collectibles — the least developed segment in Vietnam.

Transmission is distinctive: an international title at the top raises amateur participation with a three-to-six-month lag, while corporate sponsorship responds more slowly and depends on whether that title was reported under the correct discipline. A schematic drawn on paper is only the residue of decisions already made at the table. Here the schematic was mislabelled at the start, so every downstream effect is skewed.

The Counterintuitive Angle: Blurred Labels Are Not a Media Failure

My first reflex on seeing a merged-label report is to blame the writer. Look closer and the problem sits with the data sources more than the writer.

A Vietnamese sports reporter covering billiards rarely has a unified source. Calendars for six disciplines sit in six places. Rankings sit in six places. Regulations are scattered and rarely translated. Player records live on personal pages, unofficial sites, and screenshots.

When sources are fragmented, writing at the billiards level is the only time-feasible choice. It is rational behaviour under irrational conditions. Blaming individuals solves nothing. What is needed is infrastructure: a discipline-labelling standard for every report, a regulation cross-check sheet, and a habit of video verification before publishing any figure. None of that requires a large budget. It requires discipline.

And here is the second counterintuitive point. Splitting labels does not reduce the appeal of Vietnamese billiards. It increases it. A reader who understands that a player stands at the top of the world in one specific discipline cares more than a reader told only that Vietnam has a billiards star. Specificity creates attachment. Vagueness creates indifference.

A system of analysis is only trustworthy when I can find its failure point. Here the failure point is obvious: we have players, events, and audiences, but no data foundation for anyone — journalist, coach, or fan — to build on.

Systemic Risk

If I had to rate the risk of this situation, I would not say high or low. I would say indeterminate, and say why. Low is false reassurance. High is unsupported. The honest position is that we have a monitoring gap at the data layer, and that gap may or may not hide a problem.

The concrete, actionable risk is information-integrity risk. When an unverified figure is published, it gets cited. The second citation drops the source. The third becomes fact. I have seen this in other sports and do not want it repeated in Vietnamese billiards, where the data layer is thin enough that one error can create a variant that survives for years.

A Minimal Proposal

Four actions, kept deliberately simple so they can start this week. First, every billiards report carries a discipline tag in the opening line — snooker, pool 9-ball, American 8-ball, Chinese 8-ball, carom three-cushion, or pyramid. If a story spans disciplines, split it. Second, every format is stated: racks, race length, ranking or invitational. Third, every quantitative figure carries the note verified against video or a specific source; if it cannot be verified, it is not used. Fourth, when there is no compliance signal, write not enough information to assess, never nothing to see here.

Closing

Back to the hall on Nguyen Thien Thuat Street. The three men are still there, still watching, still arguing. They are not wrong. They are simply describing three different sports with the same word.

The point is not a complaint about writing. It is a question for me and my colleagues: if six months from now a Vietnamese cueist wins a world title in a discipline most domestic viewers have never heard named, do we have the foundation to tell that story properly, or do we start again by explaining that billiards is six different sports? Champions are not the unbeaten; they are those who err less often under the same pressure. Vietnamese billiards media does not need to be perfect. It needs to label correctly before it starts counting.
