The Wrong Ruler: How Vietnamese Billiards Keeps Misjudging a Generation

In July 2026, at a billiards club on Le Loi Street in Hai Phong, a nineteen-year-old trainee was led to a pool table for an entrance assessment. He had grown up on the three-cushion table, drilling shots along cushions two and a half metres long, calculating force to the millimetre and spin with the tips of two fingers. That day he was asked to play ten racks of 9-ball while an evaluator recorded his run-out rate and his break success. He ran two racks out of ten. The sheet read: below threshold. I sat in the corner with my spreadsheet open and added a line the form had no field for: cushion contact speed steady at 0.4 seconds per contact, cushion-path error under two degrees, cue-ball position retained after three cushions in 71% of attempts. On a three-cushion table those numbers belong to a player with a foundation. On a pool table they mean nothing, because nobody measures them. The trial ended with a conclusion that was correct given the data set used, and wrong given the nature of the game. The boy was filed under needs more time, when what he lacked was a different ruler. It has repeated often enough over five years for me to give it a name: a classification error. Vietnamese billiards runs through three separate channels, and each channel has its own rule system. The first is carom, one-cushion and three-cushion, governed internationally by the UMB. It is the oldest channel, rooted in the French colonial period, anchored in Ha Noi, Hai Phong, Ho Chi Minh City and a handful of provinces with long club traditions. The second is pool, 8-ball, 9-ball and 10-ball, under the World Pool-Billiard Association. Pool arrived later and surged with the urban entertainment-club wave, carried by names such as Duong Quoc Hoang and Nguyen Tran Thanh Tu on the regional circuit. The third is snooker, barely present outside a few private-club tables. No tournament system, no academy, no coaching pipeline. The reasons are physical before they are cultural: a snooker table is nearly three metres long, costs several times a pool table, and no discipline in Vietnam has produced enough coaches to teach it at scale. All three share one word in Vietnamese: bi-a. That is the origin of almost every misjudgement in the sport. In 2026 Tran Quyet Chien won the three-cushion world championship in the Netherlands. In 2026 Bao Phuong Vinh repeated it on home soil in Binh Duong. Those two facts show that Vietnamese carom has reached the world summit through a very narrow path: a few dozen professionals, a few training centres, and regular UMB World Cup entry slots. In pool, Vietnam has competitors at continental events and the SEA Games, but nobody has gone deep at a WPA world championship. The gap comes from competition infrastructure and air miles, more than from talent. In three-cushion the unit of measurement is average points per inning. A world-class player holds 1.8 to 2.2 over a long match; a well-grounded junior sits between 0.7 and 1.0; a beginner stays under 0.5. But the average is only the surface. Beneath it sit three other layers: cushion-path error, the deviation between the intended contact point and the actual one; speed control, the distance the cue ball travels after contact; and the structure of the leave, whether the player hands himself a favourable position for the next inning. I record all three for every trainee, updated each session, because a match average can hide one badly misjudged shot. In pool the unit changes entirely. Break quality is measured by balls potted, cue-ball position after impact and whether the second shot stays available. Run-out rate is calculated on racks with a genuine chance, not on total racks. Safety is measured by how often the opponent is pushed into a speculative shot. And there is a group of metrics three-cushion simply does not have: the jump shot, the masse, and time management under a 30-second clock. The word break is the clearest illustration. In snooker, a break is a continuous scoring sequence within one visit, measured in points. In 9-ball, the break is the opening shot, measured by its quality. Two concepts share one word, sit at opposite ends of the match, and serve opposite analytical goals. Anyone translating mechanically produces a meaningless table. That is why my first question in every consultancy session is always the same: which table is this, which rules, which tournament system. Without that answer, every spreadsheet is literature. In 2026, when junior competition froze, I opened a file tracking 41 young players aged 16 to 21 across six clubs in Hai Phong, Ha Noi and Ho Chi Minh City. Each had a page: dominant hand, original discipline, weekly training hours, number of recorded matches, and the three baseline metrics of that discipline. By the end of 2026, only 9 of the 41 had a complete baseline record. 14 had at some point been assessed with the metric set of a discipline other than the one they trained in. Six were filed as insufficient potential by a test designed for pool, while they were training three-cushion. Six out of 41 is 14.6%. Scaled nationally, that is a generation measured with the wrong ruler. The spreadsheet comes before the dream. I do not draw the future; I only measure the dust that time lays over each metric. One case. Trainee N., 17, four years of three-cushion at a Ha Noi club, averaging 0.95 points per inning with a cushion-path error of 2.3 degrees. A sponsor proposed a move to 9-ball, because pool events offer more slots and more visible prize money. After 14 months N. reached a 22% run-out rate. The threshold I use for a junior capable of competing regionally is 35%. His safety numbers sat in the best band of the tracking group, because placing the cue ball in difficult positions is exactly what three-cushion teaches hardest. His break remained weak. My conclusion was two more years, conditional on 20 training hours a week and a dedicated pool coach. The conclusion was never used. The sponsor withdrew after eight months. The economics of the two channels differ too, and economics decides who gets to play. Across more than twenty clubs I surveyed, a competition-standard three-cushion table costs 80 to 150 million dong, occupies roughly 20% more floor space than a pool table, and demands a flatter surface. A standard commercial pool table costs 25 to 60 million dong. Table time runs 50,000 to 90,000 dong an hour. A club with ten pool tables recovers its capital faster and attracts casual customers more easily than a club with ten three-cushion tables. That is why the number of pool tables has grown quickly in the cities while the number of competition-standard three-cushion tables has barely moved. Competition infrastructure determines the talent flow. More tables produce more players; more players produce more events; more events produce the data from which selection becomes possible. Vietnamese carom is strong at the summit but thin at the base. Pool is thick at the base but has no summit. The most repeated story of the past two years: Vietnamese billiards should pivot to pool, because pool has money, because pool is popular, because pool offers a route into the regional games. I went back to the calendars and the prize structures and found a different picture. Pool prize money concentrates in a very small set of global events, and entry comes largely through ranking systems in regions with dense pool infrastructure. A Vietnamese player who wants into that group must fund his own travel, his own entry fees, and months away from home. Three-cushion is structured differently: the UMB runs a regular World Cup circuit with ranking points, and Vietnam already holds regular entry slots. The cost for a Vietnamese player to reach the world top 20 is far lower than the cost to reach the pool top 20. Marginal return on investment in carom is higher, while most resources flow toward the channel with better optics. That is the counter-intuitive angle: what is being called the big opportunity is the more expensive road for a country with a carom tradition. But this is not a campaign piece for carom. The urban pool scouting network is producing what I call a lottery ticket, billiards edition: a fifteen-year-old drops out of school to train eight hours a day, a family borrows money to buy a table, a small sponsor signs a three-year deal with no injury clause, and a wrist injury ends everything. I have watched three such cases in two years. All three began with a handsome break that was filmed and posted online. Every transfer is a reverse archaeological dig: we excavate the past to find a piece for the future. In Vietnamese billiards, most of those transfers are decided by a 40-second highlight reel. What would change my verdict? Three things. A national junior circuit with separate scoring systems per discipline, not a merged one. A programme that records full junior matches so raw data replaces highlights. And a mandatory injury insurance clause in every sponsorship contract signed with anyone under 18. Watching junior matches live in Hai Phong and Ha Noi, I arrived at something simple: no player loses for lack of talent. They lose because they are placed at a table that is not theirs, and graded with someone else's ruler. Doubt exists to dig deeper before a discovery is announced. Vietnamese billiards does not need another miracle; it needs the fragments of history, geography and people assembled into one solid structure. The sediment of a generation of cueists sits exactly there: the ones forgotten when the lights go out. And out there, nineteen-year-olds are still waiting for a ruler built for them.
