Chessboard Geometry: Vietnam and the Gap Behind Its Leading Light

I often rewatch games with the sound off. No commentary, no crowd noise, only pieces sliding across wood. On one such evening, I stopped at move twenty-three of a top-level game: a knight left the central square, making room for a pawn to advance, and the entire position turned. The commentator called it a "surprise move." I saw a calculation that had been prepared ten moves earlier. When the stands are empty, you hear the pieces touch the board. That is real chess.

That story repeats itself every time I sit down before a Vietnamese game. We have a leader the whole chess world has to name. But behind him lies a gap few are willing to look at directly.

A lighthouse and its shadow

Le Quang Liem was born in 2026 in Ho Chi Minh City. He earned the Grandmaster title at just fifteen, and has since been Vietnam's highest-rated player on the FIDE list. His personal peak is an Elo of 2740 — a number very few Asian players have reached. He won the Aeroflot Open two years running, in 2026 and 2026, a tournament that gathers hundreds of strong players and has launched many great names.

Behind him, Nguyen Ngoc Truong Son is the next name, also a Grandmaster, also born in 2026. In the women's game, Pham Le Thao Nguyen held a high position for many years. But when I place the numbers side by side, a different picture appears: Vietnamese chess has a peak, but a thin base.

I do not say this to diminish anyone. I say it because the data does not let me say otherwise. A country with one player in the 2700 group and no second or third chasing him is a country betting on an individual. And chess is a cruel sport for such bets.

There is a harsh rule every mind sport obeys: a player's peak usually arrives between twenty-five and thirty-five, and begins to decline afterward. That means a generation's time is not infinite. Every year that passes without investment in a cohort is a year that cannot be recovered.

Chessboard geometry and the price of misreading it

Let me recall a game to explain what I mean. In the opening, each side does not merely develop pieces — they draw a structure. Picture the board as a plane, with each piece controlling a zone. When a player pushes a pawn, he does not stop at occupying a square; he changes the geometry of the entire center. Diagonals open, files empty, and a knight can suddenly jump to a square it could not reach three moves earlier.

That is the true language of chess: not isolated moves, but the movement of space. I call it chessboard geometry. People say girls know nothing about tactics. So I write for them to read.

At the top level, the difference between a 2650 player and a 2750 player is not who calculates further — engines have flattened that gap. It is who understands the structure they are creating, and who can accept the trade-offs. You cannot control the center, keep your king safe, and attack on both wings at once. Every move is a renunciation. The good player renounces the right thing.

This holds in both the opening and the endgame. A setup like the Berlin Defense is not attractive to a mass audience, but it is one of the most trusted weapons at the top, because it turns the opponent's attack into a tedious technical problem. By contrast, sharp options like the Najdorf or the King's Indian hand the opponent a chance to counterattack. No opening is better than another. Only more suitable for the person sitting at the board.

This is why I always reopen games with the commentary off. Commentary often tells you which move was "good" or "bad" based on the result. But with the sound off, you must ask yourself: what did the player see at move twenty-three? How far ahead had he calculated? And most importantly — what did he believe in?

Tactics never lie; only those who read them do.

The engine era and the trap of perfection

Opening preparation has never been more important, nor easier to copy. A young player today can access millions of games and machines stronger than any human. That means the knowledge gap between countries has narrowed. But it also creates a trap: dependence.

When everyone has the same engine, the advantage no longer lies in what you know, but in what you understand when the engine stops guiding. At move twenty, no one tells you the next move. That is when instinct and structural understanding speak. And instinct is forged only through thousands of real games, against real opponents, under real pressure.

This is why I stress international competition. A player can learn hundreds of openings in a room, but cannot learn the feeling of sitting across from a foreign Grandmaster, clock running, with thirty seconds left. That feeling is not in any book. It exists only at the board. And that is what Vietnam lacks: real boards, enough of them, for a real generation.

The data: when the numbers tell a different story

Vietnam's chess competition system runs around a few major events: the Chess Olympiad (national team), Asian championships, and a number of international opens. Le Quang Liem is regularly the core of the Olympiad team, playing board one. That means whenever he is present, the pressure on one person is enormous. And whenever he is absent, the team loses its anchor.

A strong team is not measured by its strongest player, but by its weakest across four boards. If your board one wins, but boards three and four regularly lose, you still lose the team match. This is the arithmetic that leading chess nations solved long ago: they do not train one star, they train a constellation.

Look at the powers and you will see it. India has several young players in the 2700 group at once. China has an entire generation of dominant women. The United States, Armenia, Azerbaijan — each has a thick pipeline. Vietnam has a sharp peak and a steep slope.

I am not saying we have no young talent. I am saying we lack a system that turns talent into class. What does a young Vietnamese player need to rise? Strong opponents to sharpen against, international events to build Elo, coaches with top-level experience, and money to travel. Those four things do not appear on their own. They must be built.

And here the data turns cold: Elo does not rise in silence. It rises only when you beat someone stronger than you. If you only play at home, you will forever be the best in a small room.

The four tiers of a large board

To understand Vietnam's position, picture world chess as four tiers. The top tier is the players contending for the world title, around 2800. The second tier is the challenger group, 2700 and up — where Le Quang Liem once stood. The third tier is rising stars, 2550 to 2650, usually in their twenties. The fourth tier is the reserve, young players the world does not yet know.

A healthy chess nation has all four tiers, and more importantly, a flow from the fourth tier to the first. Vietnam has a second tier with one name, and a fairly crowded fourth tier from which few cross the line into the third. The bottleneck lies there. Not at the peak, but at the transition.

The blind spot: we love the lighthouse so much we forget the shore

This is the part I must say plainly, even if it is not easy to hear. The greatest mistake of Vietnamese chess media is turning one person into an entire chess scene. Every time Le Quang Liem wins, we celebrate as if the whole sport had triumphed. Every time he loses, we despair as if the whole sport had collapsed. Both are illusions.

An individual cannot carry a system. And our focus on him inadvertently obscures the more important question: who comes next? If Le Quang Liem retired today, whose is board one? If the answer is "unknown," that is the real news.

I understand why we do it. A star is easier to tell than a system. A personal story spreads more easily than a ranking list. But my job is to read the board, not the headline. And on the board, no move exists alone.

Looking ahead

I do not write this to assign blame. I write because I believe Vietnamese chess stands at a crossroads, and that crossroads is decided not by a single game, but by how we look at it.

If we keep loving the lighthouse and forgetting the shore, we will have a few more years of celebration, then a lost decade. If we begin investing in the next generation — in the fourteen- and fifteen-year-olds training in small clubs — then in ten years, board one will no longer be a question.

Sometimes, to understand a game, you must stand in silence longer than others can bear. I have stood still long enough before Vietnamese games. And what I await is not a miraculous move, but a generation.
