One Word, Three Ecosystems: Where Vietnamese Billiards Coverage Slips

On a weekend I sat in a billiards club on Lach Tray Street in Hai Phong, looking at three tables placed close together. The table on the left was carom three-cushion: no pockets, a playing surface of 2.84 by 1.42 metres, three balls. The middle table was nine-ball pool: six pockets, a 2.54-metre surface, nine balls. The table on the right was snooker: twelve feet long, 22 balls, pocket openings so tight that a beginner has to squint. The three tables stood less than four metres apart. But if someone asks where Vietnamese billiards stands on the world map, the answer depends entirely on which table the person answering is standing at. Over the past two years I have noticed a recurring sentence pattern in Vietnamese sports outlets: Vietnamese billiards wins the world title, Vietnamese cueists break into the world's leading group. Reading closely behind those headlines, I always find three different competition systems, three different governing bodies, three different prize structures and three different definitions of the word champion. Rolling them under one name does not make an article easier to read. It creates a classification error, and in analytical work a classification error is always more expensive than a data error. Vietnam is one of the few countries where all three billiards ecosystems exist at meaningful scale. Carom three-cushion has more than thirty years of depth here, tied to the world governing body UMB and the umbrella body WCBS, played on a pocketless table where the objective is to contact three cushions before striking the object ball. Nine-ball and ten-ball pool sit under the World Pool Association and commercial promoters such as Matchroom, played on a six-pocket table. Snooker belongs to the World Professional Billiards and Snooker Association and its commercial operator World Snooker Tour: 22 balls, a twelve-foot table, a ranking system that rolls over two seasons. These three ecosystems share exactly one thing: Vietnamese calls all of them bi-a. Names such as Tran Quyet Chien, Nguyen Duc Anh Chien, Ma Minh Cam and Ngo Dinh Nai belong to the first ecosystem. Duong Quoc Hoang belongs to the second. In the third, Vietnam has no name large enough for the public to remember. When a Vietnamese carom player wins a World Cup leg, that is an achievement in a discipline where Vietnam has a genuine coaching base, with dozens of clubs in Hanoi, Da Nang, Binh Duong and Ho Chi Minh City and a generation of cueists trained since the 1990s. When a Vietnamese pool player goes deep at a WPA event, that is the story of a very different base: fewer domestic events, fewer international entries, and a transition path from amateur billiards to professionalism that remains thin. Snooker in Vietnam has almost no pipeline at all: no professional tour card system, no domestic Q School, no ranking event recognised by WST. Three stories. One name. And a habit of building bridges between them. The first word to bend is break. In nine-ball, the break is the opening shot, and its quality determines most of the first-turn advantage. In snooker, a break is a sustained scoring visit, and break-building is the craft of constructing those visits around the black and the pink. The two concepts share nothing but the word. An article describing a spectacular break in a snooker match is importing a concept from another discipline. Likewise, 147 exists only in snooker; break-and-run exists only in pool and Chinese eight-ball; average means something only in carom. Each discipline has its own metric set, and no conversion rate exists between them. In carom three-cushion the central measure is average points per inning. The world's leading group operates between roughly 1.5 and 2.0, meaning each inning yields between one and a half and two points, and a run of fifteen is the moment that builds a reputation. In snooker the measures are pot success, safety success and century frequency. In pool they are break-and-run rate and clearance rate in a single visit. These three datasets cannot talk to each other. A carom player averaging 1.8 implies nothing about his pool break, and a snooker player with two hundred centuries implies nothing about his three-cushion control. Table geometry forbids inference as well. A snooker table is twelve feet by six, with pocket openings of roughly 3.5 inches and a ball diameter of 52.5 millimetres. A pool table is nine feet, with pockets between 4.5 and 5 inches and a ball diameter of 57.15 millimetres. A carom table has no pockets, uses a 61.5-millimetre ball, and its bed is heated to reduce the effect of humidity on the cloth. A cueist moving between these tables must rebuild the entire feel: stroke thickness, follow-through length, contact angle, the reading of cushion rebound. That is why professionals rarely compete across disciplines at the highest level, and when they do, they usually need one to two seasons to re-establish themselves. Governance and ranking systems are equally separate. WST runs a two-season rolling ranking with a professional tour card boundary around world number 64, and every point is tied to WST-sanctioned ranking events. The WPA governs pool with its own points structure. UMB governs carom with points allocated by event tier. A world title in one system converts into nothing in another: no entry, no ranking points, no eligibility. Prize structure is where the divergence is sharpest. The World Snooker Championship pays its winner around half a million pounds, but the cost of surviving on that tour is correspondingly large: travel, accommodation, and a season that runs almost the full year. Chinese billiards events, known as heyball, offer purses competitive with mid-tier snooker ranking events while conferring no snooker ranking points whatsoever. Carom pays less in absolute terms, but the cost of competing is far lower, and for a Vietnamese cueist carom is the only one of the three disciplines that can sustain a career on tournament income alone. I know this because I once got it wrong. In 2026, when domestic events stalled, I built a spreadsheet tracking 47 young cueists from clubs in Hai Phong, Hanoi and Ho Chi Minh City, recording discipline, height, matches played, minutes played and average score. In the third month I realised the spreadsheet was useless in precisely its first column: I had merged three disciplines into a single achievements column, and every comparison downstream was contaminated from there. I had to split it into three separate sheets, three metric sets, three grading scales. The work took six more weeks. I found 47 gems not because I have a sharp eye, but because I am too lazy to trust the reports handed to me. And of those 47 reports, 31 did not state the discipline. There is an unspoken assumption running through most Vietnamese billiards coverage: that carom success is evidence of Vietnamese billiards strength in general. That assumption is structurally false. Carom is strong because we have thirty years of club building, coaches, domestic events and a generation that passed the craft down. Pool inherits none of it. Snooker inherits even less. A country can hold a carom world title and simultaneously have no snooker player inside the top 100, and there is no contradiction. It is simply the consequence of three ecosystems with three different pipelines. The reverse direction is no less troubling. Because Vietnamese snooker is weak, almost nobody tracks the small group of young cueists practising in private clubs, where the table sits in an air-conditioned room and the fees are paid by their families. No ranking, no reports, no one counting. A seventeen-year-old snooker cueist can improve for three years without leaving a single trace of data. A cueist's twenties resemble a young geological layer: beautiful on the surface, prone to collapse if the foundation is never checked. Scepticism is not there to deny; it is there to drill deeper before a finding is published. And this is where I have to state something I remind myself of every time I sit down to write: the spreadsheet comes before the dream. I do not draw the future; I only measure the dust of time settling on each metric. What needs doing is not large, but it has to start at the front of the chain. Every billiards headline should carry a discipline tag in its first sentence. Every statistics table should have a discipline column before the achievement column. Every report on a young cueist should state which table, which rule set, which ranking system, and when the data was collected. Based on my experience following matches, the next Vietnamese name to appear on a world stage will come from one of those three tables on Lach Tray Street. The analyst's job is not to predict the name. Our job is to know for certain which table it came from, and to stop calling it by a generic name while convincing ourselves that all three tables are moving forward at the same speed.
