Move 68 and the Limits of the Body: Vietnamese Chess After a Seven-Hour Game
Le Quang Liem's clock stopped at 0:41 as the game entered its seventh hour. He had not run out of time. He laid his king down himself, extended his hand, gave a quick bow to his opponent, and left the board. In the spectator area, a small group of young Vietnamese stood up to applaud. That applause was not for a victory. It was for a game that had gone to the very edge of what a human brain can endure for nearly seven hours.

I stayed seated long after the pieces had been swept back into the box. Twenty years in this trade — from a provincial player, to a tournament organiser, to a commentator, and now to a writer — have taught me that the moment a game ends sometimes says more than the game itself. This time, that moment spoke of something Vietnamese chess has delayed facing for too long: we are strong in the opening, decent in the middlegame, but once we reach long endings, the body starts speaking on behalf of the mind.
A generation has reached its ceiling
Le Quang Liem was born in 2026 in Ho Chi Minh City. He has been Vietnam's number one player for more than a decade, having climbed into the 2700 Elo range — a milestone very few Asian players ever touch. In 2026 he won the World Blitz Championship, one of the rare bright marks of Southeast Asian chess on the global stage. Beside him, Nguyen Ngoc Truong Son — born in 2026, also from the south — has been his companion for two decades, the man who helped him lift the whole national game to a new level.
But at thirty-five, both have crossed to the far side of the slope. In chess, thirty-five is hardly old — many elite players still win world titles at forty. Yet modern chess is no longer a game of the mind alone. It is a game of the mind set on a body that must withstand six, seven, even eight hours of absolute tension, with a heart rate that at times surges past one hundred beats per minute, with a calorie burn comparable to a long run, and with breathing compressed by every calculation.
I have sat in enough tournament halls to see this with my own eyes. I once watched a young player leave the board after the ninth round of an event and faint in the corridor. I once saw an international grandmaster eat an entire spare bar of chocolate between two games because his blood sugar had crashed to alarming levels. And I have seen older players — like Le Quang Liem that day — calculate flawlessly for five hours, then suddenly play a move they themselves could not explain afterwards.
Vietnamese chess grew up inside a paradox. We have outstanding players trained under very modest conditions, yet a physical-conditioning system built specifically for chess barely exists. There is no dedicated nutritionist for the national chess team. There is no strength-and-conditioning room. There are no baseline tests for sleep and circadian rhythm during long events. We train the opening on computers, but we have never trained the body to bear the cost of the endgame.

This did not begin today. It was forecast years ago, when Le Quang Liem's golden generation entered its peak. But because we fixated on each individual win and each individual feat, we overlooked a more systemic question: what happens when our players must play twice as many games, in a short span, against younger opponents?
At international events, the answer is slowly emerging. At Chess Olympiads, where each team plays nine to eleven games over two weeks, Vietnam often starts well and then stalls in the final stretch. In knockout events, where a player may have to enter a tie-break the same night, our stamina tends to run dry just as the opponent begins to accelerate. That is not coincidence. It is a pattern.
The price of move sixty-eight
Looking back at that game, I divide it into three parts. The first twenty moves were a theoretical opening, balanced to the point of predictability. From move twenty to move fifty, both sides played at a very high level, with sensible exchanges and a position any engine would assess as almost dead equal. That was the mind's portion, and both players completed it perfectly.
Then came the endgame. And that is when everything changed.
On move sixty-eight, Le Quang Liem should have found a sequence to hold the draw. An engine would find it in seconds. But a human being after six and a half hours is no longer an engine. The head still knew what to do; the hands were no longer steady enough to do it. He made a small error — one that, on another day, he would never make. Not an error of knowledge. It was the error of a body whose reserves had run dry.
The key point Vietnamese chess has never fully priced in sits here: in the era of the engine, intellect has become a commodity, while stamina has become the scarce asset.
The statistics suggest something worth pondering. A standard game lasts four to seven hours. In events like the FIDE World Cup, with its knockout format, a player may have to play a tie-break the same night — sometimes ten hours at the board within twenty-four. A sports-physiology study published in 2026 found that an elite player can burn more than six thousand calories in a single long playing day, and that their average heart rate during tense calculations is comparable to someone jogging continuously.
Seen that way, chess is plainly a sport — yet we still train it like a school subject. And that very gap is eroding our best players at the exact moments that decide everything.
I once sat beside a foreign coach at an international event and heard him assess Vietnam's young players. He said something I wrote straight into my notebook: "Their technique is better than their bodies." It was a compliment wrapped in a reproach. Good technique can win you a five-hour game. But to win a two-week tournament, good technique alone is not enough.
The same holds in reverse. The players currently dominating world chess all share one trait off the board: they are prepared by full support teams, and they never enter the seventh game of a tournament with an abandoned body. At the very top, the gap between leading players has narrowed to the point where technique is nearly equal. What remains is who slept better, who ate the right meals, and who stayed sharp to move seventy.
The trap of the lone hero
There is a far more comfortable way to tell the story, and I see it used far too often. It is the tale of the lone hero — the genius who decides a game with one historic move in a moment of transcendence. When Le Quang Liem loses, we say "he collapsed". When he wins, we say "he shone". Both phrasings ignore most of the story: the role of the system behind the board.
Chess may be the most counter-intuitive discipline of all when it comes to the ratio of players to support staff. An elite player needs an opening coach, a middlegame coach, an engine-analysis expert, a conditioning specialist, a nutritionist, a sleep manager, and a whole psychological team for knockout events. That is a machine — not a lone human sitting at a board.
Vietnam has produced players talented enough to stand with anyone. But we have never given them a truly professional support machine. And that is precisely what makes each of their defeats look like a personal tragedy, when in truth it is a failure of the system.
I do not believe every defeat is beautiful. A wrong move is still a wrong move, and the one who errs must answer to the board. But that responsibility should not eclipse a larger one: the responsibility of a chess nation that has sent its best players into long wars with thin physical baggage.
If we truly want Vietnamese chess to take another step, there is far more value in building a conditioning and psychology pathway for young players, and turning international trips into a proper preparation process rather than lonely journeys to "test ourselves". That is the kind of work that produces no headlines. But it is exactly the kind of work that decides the moves at the sixth hour.
I know some will say we have far too little money to think about conditioning specialists or sleep managers. But look at the small chess nations of Europe — countries of only a few million people, with modest budgets, that still regularly place players among the world's strongest two hundred. Their secret is not money. It is that they treat chess as a complete sport, not an intellectual pastime.
Back to that game. After signing the scoresheet, Le Quang Liem walked alone around the corridor. He looked at no one. Over more than twenty years of watching Vietnamese chess, I have learned that such silences are where darkness and light coexist: on one side failure, on the other a generation of children who will grow up without having to search for a drawing move with the last strength of an exhausted body.
The game ended, but the applause still echoes inside me. Not applause for a result, but applause for a belief: a chess nation that places the human body in its rightful position is a chess nation that has begun to mature.
What to watch next season
Vietnamese chess is not short on talent. What we lack is the patience to build a quiet infrastructure — training rooms, specialists, long-term pathways for young players. Next season will bring more games stretching past midnight, more careers weighed on the scale of a sixty-eighth move. The question is no longer who will win those games. The question is whether we have prepared enough for our own players to last that far.

I believe the day will come when Vietnam's name appears among the world's top ten players. But I also believe that moment will not come from one exceptional individual — it will come from a system brave enough to admit one simple thing: a chessboard holds pieces, and it also holds the calluses of a human life.
