One Word, "Billiards", Hides Four Different Competitive Systems

At a billiard club by the Liverpool docks, closing time is two in the morning. Every night there is an argument. One man insists Ronnie O'Sullivan is the greatest cueist who ever lived. The man beside him names a world pool champion. They use two vocabularies that have nothing in common, argue with two systems of measurement that have nothing in common, and both believe they are discussing the same sport. The word "billiards" they use to cover it all is, in English, an umbrella far too wide.

I sit there, order a cup of tea, and think of a line I have used many times when writing about football: I do not watch to be entertained, I watch to decode. With billiards, the same applies. And the more I decode, the more I see that most of the misunderstanding around this discipline begins in a very small place: people name the sport incorrectly.

You may be thinking this is nitpicking over wording. Consider a familiar sentence: "Vietnam has a world champion billiards player." True or false? It is true if we mean carom three-cushion, or pool, or certain free-form disciplines. It is false — or at least incomplete — if we silently mean snooker. The same word, two different truths. A careless reporter turns a victory in one system into a false claim in another.

That is why I am writing this: not to tell a heroic story, but to rebuild the framework that football already has — the boundary between competitive systems.

Context: four systems under one name

Used narrowly, "billiards" refers to cue-and-ball games on a table. Broadly, it has been collapsed into a single mass, and that collapse erases at least four branches that differ in technique, rules, and the economy surrounding them.

The first branch is snooker — a 12-foot table with six pockets, fifteen reds and six colours. The playing surface is 3,569 mm by 1,778 mm; the ball is 52.5 mm in diameter; the corner pocket is only about 86 mm wide. That gap between ball diameter and pocket mouth is an entire technical doctrine.

The second branch is American pool — 8-ball, 9-ball, 10-ball — played on a 9-foot table, a playing surface of 2,540 mm by 1,270 mm, balls 57.15 mm in diameter, corner pockets around 114 mm. Compare the last two figures — 86 mm against 114 mm — and you understand why a snooker player and a pool player cannot simply swap chairs for an evening.

The third branch is Chinese 8-ball. It is the most interesting intersection: a 9-foot pool table with snooker-style pocket cuts, using pool balls 57.15 mm wide. Pockets are therefore relatively tighter against the ball, demanding far more precision than Western pool. That is why it grew into its own competitive ecosystem in China, with its own prize funds and its own specialists.

The fourth branch is carom — including three-cushion, played with no pockets at all. A three-cushion table runs about 2,840 mm by 1,420 mm, with three balls 61.5 mm in diameter, and the only goal is to strike three cushions before contact. No pockets, no reds, no colours. You cannot describe carom with the phrase "pot the ball."

Then come English billiards, Russian pyramid with balls reaching 68 mm and punishing pockets, and French free-form games. Each branch is a world.

When a report says "cueist X is a world champion," the average reader cannot know whether that means snooker, 9-ball, carom or pyramid. They are given a name but no frame of reference. And without a frame of reference, every comparison that follows floats.

Core analysis: different structures produce different techniques

I spent seventeen years commentating snooker for VTC, spanning the era of Steve Davis and Stephen Hendry. What I learned was not how they played but how they thought. And how they thought was dictated by the table.

On a snooker table, a 52.5 mm ball sits inside a pocket of 86 mm — the ball takes up more than half the opening. There is no wide margin for error. You cannot have "the right idea, slightly off execution." That is why snooker has break-building: a good pot must come with a white-ball route that unlocks the next one. A great snooker player is not the one who pots most, but the one who controls the cue ball to sustain a scoring run.

On a 9-foot pool table, a 114 mm pocket against a 57.15 mm ball means the ball occupies exactly half the opening. The margin is twice as wide. Pool technique therefore leans on power, on cut angles, on the break and the jump. A pool player can win with one career stroke — almost unimaginable in long-format top-level snooker.

Carom three-cushion eliminates the concept of pocketing entirely. There, players count cushions. Every scoring shot is a geometry equation involving three cushion contacts before the correct ball is struck. A great carom player need not know what potting means in competitive terms, and a great snooker player can be utterly lost at a carom table.

Three systems, three spatial problems. When you watch a snooker player, you praise the white-ball route. When you watch a pool player, you praise the break and the cue-ball control after it. When you watch a carom player, you praise the cushion. Those three criteria cannot be swapped, and commentary using the wrong criterion sounds fluent while saying nothing.

I have one rule when analysing: the skewed diamond only appears when you stop looking at the ball. In snooker, the skewed diamond is the cue-ball position after the shot — the thing that decides an entire scoring run, yet falls outside the broadcast frame when they zoom in on the object ball dropping. In pool, it is the cue-ball lie after the break — the thing that decides who controls the rack. In carom, it is the direction of the third cushion — invisible until the point is scored.

In all three, the skewed diamond only reveals itself when you stop watching the rolling ball.

This is where I see Vietnamese coverage slip most often. It clings to results: who won, what score, what record. It rarely rebuilds the table's structure to explain why that result is possible in one system and not another. A 147 maximum in snooker means nothing in carom; a scoring run in 9-ball cannot be compared with a century in snooker. Yet from the headline alone, they all sound alike.

I once tried an exercise: take any billiards report, delete every tournament and player name, then ask yourself which sport this is. Most reports do not contain enough to answer. That is a serious signal about information quality. Geniuses always leave a gap few can measure — and the first gap in billiards journalism is the name of the sport itself.

Structure also flows down into the tournament system. Snooker has three Triple Crown events: the World Championship at the Crucible, the UK Championship, and the Masters. Their prize funds sit well above regular ranking events, and the formats are long — a World Championship final can stretch to 35 frames across two days. Pool 9-ball uses short formats, many events a year, high variance, and far more room for outsiders. Chinese 8-ball is organised around a huge market in China with a very different event architecture.

If you cannot tell these three systems apart, you cannot tell apart three entirely different kinds of psychological pressure: the pressure of a long multi-day scoring run in snooker, the pressure of a short "win or go home" format in pool, and the pressure of a decisive cushion shot in carom. Three kinds of people, three kinds of nerve.

Contrarian angle: media and markets flatten everything

Here I must say what I believe is the industry's biggest blind spot: fragmented governance sits alongside flattening in media.

Each system has its own governing body. Snooker and professional pool in Britain operate under separate organisations, with a professional players' association handling discipline — including betting and match-fixing cases. Carom has its own world federation, largely tied to Europe and Asia. Chinese 8-ball is tied to Chinese associations. These bodies share no rulebook, no ranking system and no disciplinary procedure.

Yet media collapses them all into "billiards," and betting platforms repeat the label.

I have followed the sport's major disciplinary cases. In 2026, John Higgins — one of snooker's greatest players — was splashed across the papers over match-fixing allegations. The investigation concluded he did not fix a match, but found he had acted in a way that damaged the sport's image, and he was suspended and fined. It was important not merely because a big name was involved, but because public opinion convicted him before the disciplinary process finished.

In 2026, a larger wave of discipline arrived: a group of Chinese players received sanctions of varying severity, including long suspensions and one ending a career. It shook both professional snooker and pool.

I raise these two cases not to judge individuals. I raise them to show a structure: when a discipline is collapsed by media, a scandal in one branch is instantly read as a scandal of all "billiards." And when trust is hit as one mass, the damage falls evenly on every branch — including those with no involvement at all, including carom and pyramid, where nobody is fixing anything.

This is what I call the side effect of naming a sport wrongly.

There is a second contrarian point about data. People love big numbers: maximums, consecutive scoring visits, title counts. But those numbers only mean something inside the system that produced them. Remove the reference frame and a big number becomes an attractive but meaningless ornament. Sports analytics in general, not just billiards, suffers from this: packaging data to show off rather than to verify.

I have a habit when reading a report: find three different explanations for the same fact, then ask which ones the available data rules out. In billiards, most reports do not give me enough to rule out any. That is not the reader's fault.

What stands out: the match ends at the eleventh angle

In football, I once wrote that a match ends at the eleventh angle — meaning the stand the broadcast gives you is only one of many. Billiards is the same. A shot filmed from behind the cue ball shows you the line of the ball but not where the player's eyes are, how the feet are set, how the grip tightens into the stroke. The decisive thing lies in the beat before the shot begins.

I have spent many nights at small events in England, sitting close to the table, watching only the feet. Not the ball. What I learned is that a good cueist withdraws the foot before the stroke. Nobody films that withdrawal, nobody scores it in a technique report, yet it separates the consistent from the explosive. The gap between those two states is what I tend to measure.

In snooker, I named a zone the way I once measured the ground Modric occupied on a football pitch: not distance to goal, but distance to the point where the opponent must decide. For a cueist, it is where the cue ball must be placed so the next ball has no choice but to be easier. The best do not create hard shots; they make the next shot easier. That distance is so small that most spectators miss it.

But I must remind myself not to turn scepticism into pseudo-science. When I say "optimal cue-ball distance," that is a hypothesis, not a verified truth. There are at least three other explanations for a beautiful shot: technique, experience, and luck. Available billiards data is not enough to rule out the last two entirely. An honest analyst must say so, even when it makes the piece less exciting.

Progressive thought: the name must be right before the number can mean anything

The night at the Liverpool club ended when people began arguing over the greatest scoring visit in history. I did not join in. I stayed behind alone, thinking of something simple: if the next generation of readers were taught that "billiards" is not one sport but four systems, they would read the game entirely differently. They would ask the right question: which system does this player compete in, under what rules, in what format, under what pressure.

That question sounds dry. But it is the foundation.

As a tactical blogger now living in England and covering billiards for the local market, I see the clearest opportunity here: re-teaching audiences to tell the four systems apart. Not through lectures, but by writing correctly. A carom shot is measured in cushion routes. A pool shot is measured in positional control. A snooker visit is measured in the rhythm of the cue ball. A Chinese 8-ball rack is measured by both the third and fourth ball.

If you want to test what I have just written, try it with the next match you watch. Open the report, delete the tournament name, and ask yourself which sport this is. If the report cannot answer, you have just found a gap few can measure. And if you can answer, you have already begun to decode.

I still believe everything starts with getting the name right.
