Three Judges, One Roundhouse Kick: The Scoring Gap in Vietnamese Traditional Martial Arts Exposed After the Whistle

Round three, 47 seconds left. The red-clad fighter stepped back, rotated his hips, and threw a roundhouse kick into his opponent's ribs — a strike so loud that anyone in the front row heard it clearly. The arena erupted. But on the scoreboard, three judges pressed three different numbers: 2-1, 1-2, and one draw. The kick that the entire arena saw, the rules read as three different fights. I stayed behind after the whistle faded. The crowd drained toward the gates, still filming, still talking about one name, one kick, one robbery. What remained in the ring was the refereeing panel adding notes to the scorecard. On the empty stands, one could see more clearly what no one noticed while ten thousand spectators were shouting: the gap between what the audience calls a connection and what the rules call a valid point. In any scoring martial art, that gap exists. But in Vietnamese traditional martial arts, where the scoring system remains traditional and depends heavily on judges' perception of difficulty and precision, that gap is wider than most realize. Every time a controversial decision appears, public opinion rushes at the individual judge rather than examining the structure of the rules that produced the decision. That quarterfinal was not the first. Over roughly a decade of following national and regional traditional martial arts tournaments, I have documented many similar scorecards: the same round, the same technique, with scores diverging enough to change the result. What I collected was not a list of incompetent judges, but a map of gaps in the scoring regulation, repeating in a measurable pattern. The match context was typical. This was the quarterfinal of the national traditional martial arts championship, between Tran Duc Thinh of a famously technical central club and Le Huu Phuoc of a northern training center. Thinh was smaller but mobile, favoring single, fast strikes. Phuoc was taller, three kilos heavier, favoring clinch and takedowns. The format followed the national regulations: three rounds, two minutes each, one minute of rest. Three judges scored independently, no discussion during rounds. Points came in three groups: technical points for valid strikes, difficulty points for complex techniques, and dominance points when one fighter controlled most of the round. That three-tier structure itself created the problem: each tier requires judges to quantify something inherently qualitative. Valid strikes are relatively clear. But what counts as a high-difficulty technique, and how dominance is measured, depends on each judge's experience and worldview. This is what I want to dissect here, because it is not the fault of any individual, but of a system not standardized enough to withstand inevitable disputes. Data stays silent until someone asks the right question. For years, debates about traditional martial arts scoring in Vietnam revolved around who was right and who was wrong, rather than the key question: does the regulation allow two judges to watch the same strike and reach two opposite conclusions, both valid under the rules? When I began collecting scorecards from several tournaments, I found the answer was yes, and that was the problem. In the quarterfinal above, I accessed the detailed scorecard after the match. The roundhouse kick I opened with was recorded by judge one as a valid technical strike with added difficulty points for a complete hip rotation. Judge two acknowledged contact but judged the strike partially neutralized at the moment of impact, granting only basic technical points. Judge three saw the blue fighter slightly retreat before being hit, considered the strike to land on a guarded area, and awarded no points. Three readings, one kick. Notably, all three judges had reasoning within the current regulation. The regulation says a valid strike must land on permitted areas and not be blocked, but it does not define what partially blocked means, nor does it set criteria for measuring the completeness of a rotational strike. That gap is not accidental negligence, but an inherent feature of a system built on qualitative observation rather than clear quantitative thresholds. I tried to compare this problem with how Western martial arts organize. In professional boxing, scoring criteria are tiered clearly: effective strikes, ring control, defense, and aggression. Each category has specific descriptions to reduce interpretive space. In professional kickboxing, promoters often add a numerical contact scale. No system eliminates controversy, but all try to narrow the blind spots. In Vietnamese traditional martial arts, the problem is more complex because this is not only a sport but a cultural heritage. Techniques were not designed for a scorecard; they were designed for combat and for aesthetic motion. That makes quantifying a roundhouse kick far harder than a Western jab. Precisely for that reason, building clear criteria is more necessary, not less. This is where I want to mention a personal calibration marker. When I was a contributor to a sports site, my first assignment following a regional traditional martial arts tournament, I made a serious wrong call about a judge's decision. I assumed bias, wrote a short emotional piece, and was pulled by editors for lack of evidence. Later, accessing the scorecard, I saw the decision was fully within the rules, even if the result frustrated me. The first error is not to be forgotten, but to serve as a calibration marker. Since then, whenever a controversial decision appears, my first question is not whether the judge was right or wrong, but how far the regulation allowed him to go. If a decision is valid under the rules but against the crowd's sense, the problem is not the judge, but the rules. This is the lesson I have applied to every decision analysis since. Back to the quarterfinal. At the first data layer — the event — this is just a controversial split decision. But at the second layer — historical context — a pattern appears. For years, matchups with physical and stylistic differences like this one have frequently fallen into dispute. Smaller, faster fighters often impress audiences with clear strikes, while dominance points often lean toward larger, clinching fighters. This is the most controversy-prone decision type in any combat sport. The third layer — technical analysis — is where I want to dig deeper. Thinh's roundhouse kick was biomechanically high quality: complete hip rotation, solid base, well-timed. Tactically, it came as Phuoc threw a blocked punch and exposed his side. Under the rules, it was a valid strike with high difficulty. But in terms of fight management, it created no clear advantage, because Phuoc kept pressing immediately after and regained control of the rest of the round. This is where the crowd and the rules diverge. The crowd remembers the beautiful moment — the roundhouse kick. The rules remember the whole — who controlled the fight. In a discipline where dominance points carry significant weight, one beautiful moment cannot replace two minutes of control. But the current regulation does not specify the weight between the three point groups, nor the priority order when they conflict. Judge one prioritized the moment, judge two prioritized valid contact, judge three prioritized overall control. All three acted within the rules, but under three different priority orders. If I were writing the regulation, my first question would be: when a beautiful technical moment conflicts with fight control, which wins? Currently, the answer depends on the judge. That is a fixable shortcoming, achievable through text, without altering the essence of the martial art. Referees do not create errors; they only record what the rules already contain. This holds true in football with VAR, and in traditional martial arts with scorecards. When rules are vague, judges must fill the gaps with personal judgment. When personal judgments differ, results differ. When results differ, audiences assume bias. This loop repeats at every tournament, and the only way to break it is standardization, not judge discipline. What I noticed following traditional martial arts tournaments in the north, center, and south is regional scoring style differences. Northern tournaments tend to value clinch and takedown techniques. Southern tournaments tend to value precision and speed of hand and foot strikes. This is not personal bias, but the result of different training traditions passed down through generations. My sovereign outsider perspective — born in Japan, working in Vietnam — gives me a useful reference. Japanese traditional martial arts have disciplines with very tight scoring systems, breaking points down by technique and accuracy level. Karate has clear criteria for valid points. Judo has clear criteria for throws and landing positions. But these disciplines also took decades of debate to reach relative consistency. Interestingly, Vietnam has a latecomer advantage Japan did not: the ability to learn from predecessors' systemic mistakes. When building scoring regulations, there is no need to walk the entire path. One can learn from boxing's tiered criteria, karate's clear point grouping, and modern combat sports' weight specifications. But this requires the traditional martial arts community to accept changing traditional rules, not easy in a culture that values inheritance. The empty arena still keeps the rules; people just see more clearly without the noise. When the match ends and the stands empty, what remains is the scorecard and the regulation structure that produced it. If you only look at the angry crowd, you see an accused judge. If you look at the scorecard, you see a system needing revision. I always choose to sit in the empty arena and read the latter. One more detail. After the match, when I asked a veteran judge about his decision, he answered briefly: per the rules, I scored correctly. I did not doubt that. But when I asked whether clearer criteria for rotational strikes should be added, he paused and said: difficult, because each person sees with different eyes. That answer is the essence of the problem. Different eyes cannot be eliminated, but what can be eliminated is giving those eyes too much decision power without a shared frame of reference. I understand why audiences react strongly. They come to watch a match with a clear result, and when the result depends on interpretation, they feel cheated. That emotion is legitimate. But stopping at judge criticism means the community stays in a loop: each tournament has a controversy, each controversy has a blamed judge, and nothing changes. The only escape is to look at the structure. This is where I want to separate myself from the crowd, not to appear superior, but to point out something the crowd gets right in feeling but wrong in conclusion. The crowd is right to feel something is unjust. They are wrong to assume the cause is one person's character. Swap that judge for another and the result might differ, but the problem remains in the regulation. That is why individual criticism never solves the root cause. Another point: the lack of standard recording tools at many traditional martial arts tournaments makes post-match verification nearly impossible. In football, VAR turned controversial decisions into reviewable, analyzable events. In traditional martial arts, without multi-angle recording, we only have audience memory and judge scorecards. Those two rarely match. Installing standard recording systems at national tournaments is the cheapest, most effective first step toward resolving disputes. On proposals, I believe the community should focus on three things. First, standardize the definitions of the most contested terms, especially partially blocked strikes and rotational strike completeness. Second, specify a clear priority order among the three point groups when they conflict. Third, build multi-angle recording for national tournaments, as a basis for post-season review. None of these proposals erases the cultural identity of traditional martial arts. On the contrary, they help the discipline be seen more seriously as a modern combat sport while preserving its traditional spirit. The only issue is that they require community consensus, and consensus is often harder than technique. I return to the roundhouse kick once more. If clearer criteria had existed that day, the kick might have been scored the same on all three cards, or if different, the difference would sit in a specific criterion judges had not agreed on. Audiences might still disagree, but at least they would know what they were disagreeing with. Currently, they disagree with something vague called the judge's eye. Building clear criteria would also help the judges themselves. For years, I have seen highly qualified judges bear unfair public pressure because the regulation let them interpret without giving them a shared frame. They score by experience, and when experiences differ, they are seen as biased. This is an unfair burden on serious professionals. I recall a conversation with a veteran coach in the center. He told me the hardest thing in traditional martial arts scoring is not seeing the strike, but seeing the intent behind it. A strike can land as a result of luck, and a strike can miss as the result of a correct technical sequence. The current regulation does not distinguish these two cases. That is a very thought-provoking observation. If we accept that scoring aims to recognize technical quality rather than only contact outcomes, then criteria for technical intent must be added. Of course, this is the hardest criterion to quantify and the easiest to abuse. But ignoring it entirely creates a larger fairness problem. In the future, I believe traditional martial arts tournaments will face a strategic choice. One: keep the traditional scoring system, accept controversy as part of the discipline, and preserve cultural identity. Two: shift to a more standardized system, reducing controversy but risking the discipline's flexibility. Likely the best path is the third: standardize at the minimum level needed to reduce major disputes, while retaining interpretive space for situations where traditional technique exceeds quantification. In Japan, modernized martial arts went through this process over decades, and each discipline ended with its own scoring system, built from its own technical nature, not copied from outside. This is what Vietnamese traditional martial arts can do, if the community sits down together. My final thought is this: every time a controversial decision appears, the traditional martial arts community stands before an opportunity. Burn it into online outrage and the opportunity is lost. Turn it into data for regulation review and progress is possible. That roundhouse kick in round three, though not scored identically on all three cards, can still become one of the most valuable kicks for Vietnamese traditional martial arts — not because it was beautiful, but because it forced people to ask the right question. And I will keep sitting in the empty arena after every match, taking notes, cross-checking, waiting for a better regulation. The work of a referee is calibration, and calibration only means something when you know exactly what you are measuring.
