Vietnamese Billiards Has No Data Layer: Why I Verify with Video Before Concluding

On a Saturday night in Nha Trang, I reopened the nine-dimension analysis of billiards that a data team had sent me.

Nine sections: technique and playing style, player data, tournament format, power map, rules and governance, career and psychology, risk, media narrative, industry chain. All nine came back with the same line: insufficient information. No shot described. No player named. No tournament identified.

For a breaking-news writer, an empty analysis is a wasted night. For me, it is data. It says exactly what Vietnamese billiards needs to hear: we have a huge grassroots movement running on a data layer that is close to zero. It is also why every serious conclusion about Vietnamese billiards today has to pass through video before it passes through a spreadsheet.

Three branches, three data layers, one shared gap

Vietnamese billiards is not one sport. It is three sports sitting side by side in the same hall.

On a Saturday night at a billiards hall along Tran Phu street, twenty tables are full, balls keep clacking, and nobody records a single metric. That does not mean the match produced no data. It only means the data evaporates the moment the inning ends.

Carom three-cushion has the strongest international record. Pool 9-ball and 10-ball have grown fast for more than a decade. Snooker exists mainly at grassroots level, with fewer events and less money. Each branch has its own data system, and the degree of standardisation differs enormously.

The world billiards federation publishes average per inning for carom championships. The professional snooker organisation logs every century and every 147. Commercial pool systems log break-and-run rates. But at national and grassroots level, where most Vietnamese players actually compete every week, there is no data layer at all. Score sheets get photocopied, results land in group chats, and video sits scattered across spectators' phones.

In September 2026, Bao Phuong Vinh won the world carom three-cushion title in Binh Thuan, beating Tran Quyet Chien in an all-Vietnamese final. It is the biggest milestone for Vietnamese billiards in decades. Now try to look up the two players' average per inning across each round of that event. You will have to collect every score sheet yourself.

Measure what can be measured, draw what cannot

"Before analysing a missed shot, tell me which zone the cue ball stopped in."

That is my first principle, adapted from a rule I used when analysing football. It works in billiards for the same reason: any general description is meaningless unless it is anchored to a coordinate.

Billiards is a more purely geometric sport than football. A standard carom table is 284 cm long and 142 cm wide. A standard snooker table has a playing area of 356.9 cm by 177.8 cm. A nine-foot pool table has a playing area of roughly 254 cm by 127 cm. These parameters are fixed. They do not change by tournament, by weather, or by cloth. That means every shot can be reduced to a positional problem.

When I rewatch a match, I record five things.

The cue ball's position after each inning, dividing the table into six zones. The distance between cue ball and object ball, measured in ball units. The number of state switches, from attack to safety and back. The number of times a player leaves an opponent an easy shot from a difficult position. And for snooker, the number of innings per frame plus the number of frames won through safety play rather than centuries.

The third metric is the one I trust most. A three-cushion player averaging 1.2 can still lose to a player averaging 0.9 if he chooses to attack at the wrong moment. A score sheet does not punish a bad choice; it only averages it out. Video does punish it, if the viewer sits down and counts.

In a snooker frame, I count innings, the number of times a player plays safe while still holding an attacking position, and the number of frames won by forcing an opponent error. In a 9-ball match, I count the break-and-run rate and the rate of breaks that succeed without clearing the table. In a three-cushion match, I count the innings that end with a push to the long rail.

The lesson from getting it wrong on live broadcast

In July 2026, I commentated the World Cup semi-final between France and Belgium. Before kick-off, I declared that Belgium would press high in a 4-3-3. They dropped 35 metres deep, surrendered the initiative and lost 0-1. I said it wrong on live broadcast, and the audience noticed.

After the match, I rewatched all 90 minutes and redrew 12 transition moments. The gap between Belgium's midfield line and defensive line was 25 metres wide. From then on I set a professional rule: never assert anything before rewatching the footage, including things that look obvious.

In billiards, that rule turns into a more specific question. After this shot, which angle does the cue ball open up, and which zone does the next object ball sit in? If I cannot answer, I have no right to conclude.

There was also a time data led me astray. During the European football shutdown of 2026, I wrote a series decoding classic matches from event data. Analysing a match with an expected-goals figure of 2.8 where the team scored only twice, I found it implausible, reopened the footage and found a shot that hit the post in the 67th minute, missed by the data. Since then, every quantitative claim I make carries a note: verified against video.

"In the empty season, the data is quiet, but it speaks most clearly."

What snooker teaches the rest of billiards

Snooker is the only branch of billiards with a data layer thick enough for serious analysis, and that is precisely why it reveals what the rest is missing.

On 21 April 2026, at the Crucible, Ronnie O'Sullivan made the fastest 147 in history, recorded at 5 minutes 8 seconds. In March 2026, at the Players Championship, he reached his 1,000th career century in professional play. Those two items measure two different things: speed of decision-making, and durability accumulated over two decades.

Their analytical value lies in separating variables. A 147 and the fastest 147 in history are two different pieces of information, even though both look at the same table. That is the standard Vietnamese billiards can follow, not to compare domestic players with O'Sullivan, but to understand that a metric is only trustworthy when it isolates the exact variable the writer wants to discuss.

The blind spot sits in the framework we borrowed

"A diagram printed on paper is only the residue of every decision that already happened on the table."

The nine-dimension analysis came back empty not because the analyst was weak. It came back empty because we are imposing a framework built for football onto a sport with an entirely different time structure. Football has 90 continuous minutes with a few dozen recorded events. A three-cushion match runs across dozens of innings, each one an independent decision lasting seconds. Forcing that structure into expected-goals-style metrics is a design error, and the emptiness in that analysis is the visible consequence of it.

The second blind spot sits on the opposite side, and it is mine. I habitually trust the frame more than the spreadsheet. That instinct helps when data is wrong, and hurts when my eyes are wrong. So before challenging any metric, I ask myself: if this metric is right, what must happen on the table? If I cannot describe it, the problem is mine, and the better move is to reopen the footage.

One more blind spot belongs to the audience. We reward the hard shot, the big break, the flashy escape. But the pot success rate of a big break is usually lower than that of a well-timed safety, and no score sheet pays for beauty. A player who wins by choosing the right moment to attack will always be remembered less than a player who loses with a beautiful shot.

What I will look for at the next tournament

"A tactical system is only trustworthy when I can find its hole."

For Vietnamese billiards, the system worth probing is not on the table but in the record-keeping. If one group manages to log cue ball position after every inning at national level, within ten years we will hold something no billiards nation in Southeast Asia has: a domestic data layer to measure ourselves against.

"I do not watch a match for entertainment; I watch to find the moment the diagram starts to collapse."

On a billiards table, the diagram collapses more slowly and more quietly. It collapses in the thirtieth inning, when a player who is ahead chooses to attack from a position that does not require attacking. The audience sees a missed shot. I see a decision made two innings earlier.

At the next tournament, the first thing I will look for is the list of people who stayed behind after the match to record cue ball positions. The trophy will find its own worthy owner; a data layer does not appear on its own.
