One Name, Three Disciplines: Why 'Billiards' Is the First Question of Every Analysis

On Lach Tray Street in Hai Phong, a billiard hall stays open until two in the morning. Last Saturday night I sat there with a friend who coaches amateur players. He pushed his coffee toward me and asked: "You have followed billiards for years, so who is number one?" I asked just one question back: "Which billiards?" He went quiet for a few seconds. Then I started explaining.

In this line of work, I treat every match as an experiment and every article as an honest report of what the data says, as well as what it does not say. But one principle comes before everything else: before citing any number, I must establish which discipline it belongs to. Because "billiards" is not one sport. It is a shared name for at least three parallel competition systems, each with its own rules, its own governing body, and a completely different way of measuring achievement. Newcomers tend to merge all three into one, and that is the first mistake.

The first system is snooker. It is governed by the World Professional Billiards and Snooker Association, known as the WPBSA. The main tour is the World Snooker Tour, or WST. The peak of snooker is the Triple Crown: the World Championship, the UK Championship and the Masters. Achievement here is measured in century breaks, meaning runs of one hundred points or more in a single visit, and the maximum 147. Snooker means Ronnie O'Sullivan, who holds the record of seven world titles and the most competitive 147s in history, alongside John Higgins and Mark Williams in a trio born in 2026 that remains at the top after more than three decades.

The second system is American-style pool, most notably 9-ball. It sits under the World Pool-Billiard Association, or WPA, but most of its media pull comes from Matchroom, the force behind the Mosconi Cup. In pool, nobody counts century breaks. They count break-and-run, meaning a player breaks and clears the entire table in a single visit.

The third system is Chinese 8-ball, also called heyball. It is developed by the Chinese Billiards and Snooker Association, or CBSA, together with the table brand Joy. The rules involve called pockets, the table is smaller than a snooker table, and the pace sits somewhere between the other two worlds.

Three systems. One word. That is exactly where amateur analysis stumbles most often.

I once reread an analysis written by a friend. He praised a player for having a "stable break" and cited numbers from a pool event. But in snooker, a break is a continuous scoring run in a single visit, and a player can have several breaks within one frame. In 9-ball pool, the break is the opening shot, the split of the rack. One English word, two opposite actions. The writer had blended two definitions into one sentence without ever realizing it.

Data never lies, but I have misheard it before. And I realized most of my mishearing did not come from the numbers. It came from forgetting which discipline I was reading. Since then, every article of mine opens with a checklist of "conditions to verify", and the first condition is always: which discipline is this?

In Vietnam, the word "billiards" carries yet another layer. For most amateur players, billiards means a carom table with three balls, or a pool table with colored balls. Snooker barely appears outside international television. So when a Vietnamese reader asks about billiards, they are usually thinking of a discipline completely different from the one the person beside them has in mind.

Each discipline also has its own ranking system, scored its own way, and each updates with its own delay. In snooker, the ranking is calculated from prize money accumulated over a two-year cycle. In pool, the tours use other methods. Placing two such rankings side by side and comparing them is a meaningless calculation in methodological terms.

The calendars differ sharply too. Snooker runs an almost year-round season of ranking events, interspersed with invitationals. Pool has its own structure, tied to Matchroom tours and world championships sanctioned by the WPA. Chinese 8-ball is tightly bound to the domestic Chinese market, where table sales and viewership are both enormous.

Prize money shows a similar gap. A major snooker event offers a total purse measured in hundreds of thousands of pounds, with the champion taking most of it. A major pool event uses a different structure, spread more evenly across rounds. Even the number of events in a season differs, making any form comparison across disciplines an almost impossible task. These differences directly shape how players choose events, schedule their seasons and even choose how to play. A snooker player moving to pool must relearn the feel of the cloth, the power of the cue and even safety tactics. A Chinese 8-ball player stepping onto the international stage must adapt to a wholly unfamiliar ranking system.

This is where I want to slow down, because it runs against the common feeling.

On forums and in the media, people talk about the "world of billiards" as if it were one unified community. Stars appear together in ads, share sponsors, attend crossover events between disciplines. That feeling is pleasant, and it is designed to be pleasant.

But the data paints a different picture. Fans who follow only one discipline rarely know the champions of the other. The convergence we see is largely commercial convergence, serving sponsors and broadcast platforms, and it does not necessarily reflect what happens in competition. One missed break is an error. Three missed breaks of the same kind, across three different disciplines, are a signal that the analyst is applying the wrong frame. That is why I never use a single metric to reach a conclusion, and never compare two players from two disciplines without stating the limits.

I do not write to persuade anyone. I write so that the data has a witness. And the first witness must know which courtroom they are standing in.

If there is one thing I want my friend at the Lach Tray hall to take home, it is a question instead of an answer: next time someone asks "who is number one in billiards", ask back "which billiards". Three thousand matches taught me that one match can teach more than all of them, but only if I know which match I am watching.
