A: Phân bố điểm theo lượt cơ và thời gian chuẩn bị trước cú đánh khó, theo VangBong.vn Player Depth Index.
The clock in Liverpool read 3:12 a.m. on 11 September 2026. On screen, Tran Quyet Chien walked into the 24th inning of the three-cushion world championship final in Ankara. Across the table stood Bao Phuong Vinh. The scoreboard closed at 50-34, and in the three seconds before it changed, I did what I have done for nine years: I opened a spreadsheet and placed the cursor in a cell named "second-rail trajectory".
That cell has been empty for 214 matches.
I can tell you Tran Quyet Chien's average points per inning in that match, how long each inning lasted, which quarter of the table he left the balls in. I can reconstruct the entire scoring sequence of a quarter-final from a 720p video alone. But the thing that decided the match — the speed of the cue ball off the second rail, and how far the exit angle drifted from intent — exists in no public dataset. The reason is not the difficulty of the measurement. It is that nobody pays to measure it.

A SPORT SO MEASURABLE IT BECOMES ABSURD
Billiards is among the most physically exacting of all non-contact competitive sports. A snooker table is 3.57 metres long and 1.78 metres wide. A three-cushion table is 2.84 metres by 1.42 metres. A nine-ball pool table is 2.54 metres by 1.27 metres. Ball diameters are standardised at 52.5 millimetres for snooker, 57.15 millimetres for pool and 61.5 millimetres for carom. There is no wind. There is no pitch changing character between halves. There is no linesman misjudging a metre. Every shot begins from a state of absolute rest.
To an analyst, this is a closed system dream.
And yet when I run a nine-dimension analytical frame — technique and style, player data and form, tournament format, the power map, rules and governance, career ecosystem and psychology, risk, media narrative, and industry-chain transmission — most of the cells return empty values. Empty not because I am lazy. Empty because the structure of this sport does not generate the kind of data the model needs.
Let me take three of those nine dimensions apart.
WHAT GETS COUNTED AND WHAT GETS DROPPED

In three-cushion, the most quoted metric is the average — points divided by innings. At the top level it hovers between 1.8 and 2.2. A casual viewer reads it as a measure of strength.
Not quite. Two players averaging 1.9 can be playing two different sports.
Player A scores two points per inning for ten innings, then collapses to 0.8 over the next ten. Player B scores a flat 1.9 all match. Same average, entirely different structure. In a race to 40, A wins most of their head-to-head matches, because he can manufacture a scoring run long enough to break the pattern open. In a race to 50, that ratio inverts, because the distance is long enough for B's steadiness to grind A's variance into dust.
I tested this on three-cushion matches from the World Cup circuit that I logged myself from 2026 onwards. Same player, same opponent, change the format and the result changes, while the average does not move an inch. That is why I stopped using it as a label.
The deeper problem lies in what gets dropped. In snooker, people count breaks over 50, centuries, misses on the deciding ball. Nobody counts how many laps a player walks around the table before bending down. Nobody counts the silence after he sets the cue ball down. After nine years of reading matches, I believe the match is settled in precisely those silences.
Error is where reality signs its name. A missed pot is not noise to be filtered out; it is the trace of a decision. When Judd Trump misses an easy red on a break of 40, the thing worth analysing is not the shot. It is the three seconds of silence before it.
A POWER MAP SPLIT BY DISCIPLINE, NOT BY COUNTRY
World billiards today consists of four maps laid on top of each other, and they have almost nothing to do with one another.
Snooker: the United Kingdom still holds the human centre, but the financial centre of gravity has shifted wholesale to China. Recent World Snooker Tour calendars carry a heavier block of Chinese events than at any previous point, while England's golden generation — Ronnie O'Sullivan, John Higgins and Mark Williams, all born in 2026, with 14 world titles between them — is still grinding past the age of 50. A generation born three decades later has not replaced them. England's pipeline is far thinner than it looks.
Carom three-cushion: Europe holds the theory, Asia holds the future. Belgium and the Netherlands are the technical cradles. Turkey is the hosting market. But two consecutive world championship finals with two Vietnamese players facing each other — Tran Quyet Chien winning in 2026, Bao Phuong Vinh settling the debt in 2026 — is a signal every model built on population and historical results gets wrong.
Nine-ball pool: this is the most commercially developed front, run under the World Nineball Tour. The Philippines, the United States, Poland, Austria, Germany, Albania and Vietnam are all crowding into one bracket at once. The Hanoi Open Pool Championship was added to that system for the first time in October 2026 at the My Dinh Indoor Athletics Palace, with a published purse in the six figures in US dollars — the first time an internationally ranked pool event had based itself in Southeast Asia.
Three disciplines, three ecosystems, three speeds. Anyone who says "Vietnamese billiards is growing" without saying in which discipline is saying something analytically meaningless.
THE REAL SUPPLY CHAIN SITS OUTSIDE THE CAMERA'S VIEW
Based on my experience watching matches at events in the UK and following many Asian events online, most of the money in this sport is not in prize funds.
It is in the tables. It is in the halls that open at 10 a.m. and close at 2 a.m. It is in hourly table rental, the carbon-shaft market, and how many gloves and how much chalk move each month.
This is where conventional sports modelling fails outright. It measures the supply and demand of a sport through television viewership. Billiards does not make money from viewers; it makes money from players. A country with a million recreational players and five thousand television viewers is healthier in infrastructure terms than a country with two million viewers and three hundred players. No broadcast metric will tell you that.
And this is where I have to tell a story I do not enjoy telling.
THE BLIND SPOT LIVES ON SOMEONE ELSE'S TABLE
When the spectator-free season arrived in 2026, it took me nearly a year to grasp something I still have not written in full: in sport there are variables that cannot be encoded because they do not exist inside the match, but inside the player's head. The noise that went missing is the variable the model forgot.
Billiards is the quietest of the quiet sports. There is no roaring stand. There is a cough, a struck match, a glass touching a table. From the times I have sat near competition rooms, I believe that very silence is the heaviest pressure. In snooker, an entire arena holds its breath while a player bends down, and no probability model can assign a weight to that moment.
This leads to a counter-intuitive conclusion. For years, the analytical world believed more data would professionalise a sport. With billiards, I suspect the opposite. The more you measure, the more you measure the measurable, and the measurable part of billiards is the least important part. You can build a heat map for ball position. You cannot build a heat map for hesitation.
I once watched a young Vietnamese player lead 8-1 in a domestic event and lose 9-8. Afterwards, his stat sheet was prettier than the winner's in every column: higher pot success, fewer innings, fewer positional errors. He lost for a reason no column could hold. On the ninth inning of the final frame, he bent down, stood back up, and repeated the motion four times in the same visit. On the fifth attempt, he shot.
When the match is over, the statistic lies more artfully than the player.
There is another version of the same problem, one level up. An amateur reaching the final of an open event is usually described as proof of a development system. Most such runs happen because of an easy quarter of the draw, a friendly ballot and one explosive afternoon. Of those three variables, only one belongs to the system. A good match does not confirm a process; it confirms only that the process, on one particular day, did not get in anyone's way.
WHAT I WILL WATCH IN THE NEXT MATCH
The analysis of billiards over the next decade will not be decided by who owns the most cameras, but by who sits down and writes out what the cameras cannot see: whether the cue ball hit the cushion soft or hard, the humidity in the hall, the number of steps around the table before a difficult shot.
Every match is a hypothesis waiting to be refuted by reality. And in this sport, reality always signs its name in the cells we forgot to draw.
A question for your next match: if the loser's stat sheet is prettier than the winner's, will you fix the stat sheet, or fix the way you believe in it?
