Vietnamese Chess Ahead of the Major Season: Counting Medals Is Not Enough, You Have to Read the Clock

A chess hall is one of the quietest places in sport, and the noisiest if you know how to listen. More than a hundred boards stretching away, wood tapping wood, the click of the clock pressed at the end of every move. I sat in the back row with a notebook, logging each marker: 38 minutes left at move 24, 21 minutes at move 31, 4 minutes 12 seconds at move 38. At board seven, a young Vietnamese player thought for 19 minutes about a move an engine names in half a second. When he set the piece down, nobody in the hall knew whether it was right or wrong. Only I and the clock knew that he had just spent nearly a quarter of his time budget on a move that lay outside his preparation. He drew that game. The next day the report said, briefly, that a young Vietnamese player had held a stronger opponent. Nobody mentioned the 19 minutes.

That detail repeats at almost every tournament I have sat through. We record results, we record medals, we record the celebrations, and we let drop the one kind of data that explains why a game turned. Vietnamese chess enters the major season with a familiar paradox: a thick record of results and a thin record of data.

Over more than two decades, Vietnamese players have collected dozens of medals in regional competition and appeared consistently at the World Chess Olympiad and at continental Games. Le Quang Liem, the first Vietnamese to win the World Blitz Championship, in Moscow in 2026, was also the first Vietnamese player to reach an Elo of 2700. Nguyen Ngoc Truong Son has anchored the national team for nearly two decades. Pham Le Thao Nguyen opened the road for Vietnamese women's chess on the international stage.

At the SEA Games, chess and xiangqi have long been a gold mine for the Vietnamese delegation. At the Olympiad, the men's team has repeatedly finished in the leading group. Those two arenas differ in almost everything: the number of players, the density of grandmasters, the team scoring system, the media pressure. Yet news coverage tends to describe both with the same set of adjectives.

Most fans know Elo at the level of a definition: the higher the score, the stronger the player. Fewer know that Elo is the slowest variable in competitive chess. A nine-round event can lift a player's rating by 15 points, but shifting position on the world ranking list takes months. Every time a headline says a Vietnamese player has crossed 2700, the reader should check one more thing: was that threshold calculated from the official rating list, or from live rating, the provisional figure updated continuously during an event? The official FIDE list is frozen on the first day of each month. Live rating can jump to 2705 on a Friday and fall back to 2694 on Sunday. Both are real data. They answer two different questions.

Performance rating is the most shocking figure and the most abused one. With a sample of only seven to nine games, it depends heavily on the quality of the opposition and on one or two individual games. A player who beats two grandmasters and then loses three games to lower-rated opponents can still finish with a higher performance rating than someone who held steady form across nine rounds. The mean and the median tell two different stories, and the report tends to pick the more dramatic telling.

The most misunderstood metric is ACPL, the average centipawn loss per move. The common reading is that a lower ACPL means more accurate play. That holds only inside a narrow frame. ACPL depends on the complexity of the position, on the depth of the engine used to score it, and on whether the game opened into a sharp variation or a quiet system. A player sitting in a won position will post a very low ACPL regardless of strength. A player in a chaotic position, choosing between three moves that all lose, will post a high ACPL even after picking the slowest defeat. Comparing the ACPL of two players in two different kinds of position is comparing two quantities that do not share a unit.

Another category of data barely appears in any Vietnamese report: time. I mean the clock sheet, the record of time remaining after each move. In a standard game each player has 90 minutes for the first 40 moves plus 30 seconds per move. The clock sheet shows how long a player thought at move 12, at move 25, at move 38. It shows who is using time as a weapon. Someone who spends 15 minutes on move 12 has usually run out of preparation. Someone who spends only two minutes on move 25 while the opponent has burned 20 is the one setting the rhythm of the game. No Vietnamese report quotes the clock sheet. We have result tables, medal lists and podium photographs, but we lack exactly the data that explains why the result came out as it did.

There is one more metric almost nobody measures: the volume of opening preparation. At the top level, a novelty is a new move that has never appeared in a database. Journalists like to call it creativity. True, but not sufficient. A novelty is mostly the product of collective labour: one or several analytical assistants, a cluster of machines running engines, a private game library, hundreds of hours of variation checking. Strong federations keep salaried assistant teams, at a cost running into tens of thousands of dollars per player. Vietnam relies mainly on individual coaches and open-source engines. The novelty gap therefore sits more in infrastructure than in intellect.

The largest missing piece is the archive. Major international events publish PGN files with clock data almost immediately after the game. Many domestic events publish only a result table, sometimes as a photograph of a handwritten sheet. To analyse in depth, a writer has to reconstruct from memory, from personal notes, from a few scattered video clips. I once received an eighteen-page analysis pack for a tournament: it had an article objective, an editorial angle, a draft conclusion, even a note requiring cross-verification against data. Turning to the data page, there was not a single line of figures. No player name, no event name, no game reference, no timestamps. Every heading was full; the body was hollow.

An analysis with a complete skeleton, complete headings and a complete conclusion but no data underneath still looks exactly like a real analysis, and that is the most dangerous kind of error in sports writing.

The pressure that produces that error is real. When the major season arrives, dozens of pieces are needed every day, editors need progress, and an analysis that looks finished is always easier to approve than a note asking for delay. I have worked long enough as a sports documentary screenwriter to know what it costs to fill a gap with adjectives. When data is missing, writers tend to borrow the language of emotion: character, willpower, a historic moment. Those words are not wrong. They simply cannot be verified.

I trust footage more than testimony, because footage does not lie. Years ago, when I proposed building a technical segment around a female athlete at SEA Games 29, the proposal was brushed aside in one sentence: women do not understand sport, just write it emotionally. I did not argue. I borrowed the entire video archive, sat down to count foot strikes, logged every time marker, and built my own data appendix so that when challenged I only had to open it. I rewound the SEA Games 29 footage to find what everyone else had left behind. The two-minute technical segment built from those markers was the only part that kept the audience in their seats.

That experience taught me something that applies to chess as well: a writer does not need to win the argument, a writer needs a place to look things up. In chess, that place is the clock sheet, the PGN file, the rating list frozen on the first of the month, engine data with the depth stated.

Now the contrarian part. A SEA Games chess medal is a real achievement, but it does not measure the distance to the world summit, because it measures a different arena. At the SEA Games, players rated above 2600 can be counted on one hand. At the Olympiad, nearly every board is a grandmaster, and a mistake at move 35 costs as much as an entire regional tournament. A regional gold is treated by coverage as proof of world class, when it proves only one thing: that player was stronger than the rest of the region.

There is one more prejudice to remove. Vietnamese media love the label of prodigy, a label that is easy to attach and easy to drop. A top player's mature years usually fall between 24 and 34, when opening experience, mental endurance and tolerance for clock pressure reach a balance. A 16-year-old winning a junior title says nothing about the summit at 27. Vietnam's bottleneck is a tournament circuit dense enough for a young player to play 80 to 100 classical games a year before turning 25. We have the talent; we lack the calendar.

And there is a sentence I have heard many times in chess halls, usually from older men, spoken behind the back of a female player who has just won: why should a girl play chess at all. It sounded exactly like a sentence I once heard on another track: girls should not run hurdles. The same logic, the same kind of speaker, the same kind of data ignored, which is the score sheet. I ran hurdles all my life, I was just never timed. In chess, the clock is real, it sits on the table, and it does not care who is sitting in front of it.

So the rule I set for myself when writing about female players is simple: mention only results, technique, training process and data; do not describe appearance, do not use words like graceful, do not ask about family more than about the opening. The reason lies elsewhere: it is the condition for the piece to still be worth reading ten years from now.

The major season is approaching and there will be plenty of reports. Readers can equip themselves with one small habit: whenever they meet a claim about class, check what data it rests on, on which date it was frozen, and with what instrument it was measured. Every player knows the move is not on the board, it is in the mind of the person moving. A writer needs a place to look things up, and that place must exist before the article is written, not be assembled afterwards. If this season brings only one small change, I hope it is this: add a clock column to the result table. From that column, every story behind the game will find its own way out.
