Overview of Lethwei Rules Explained
Lethwei is not governed by a single clean ruleset. It operates across two overlapping systems and four distinct fight formats, each carrying a different purpose. If you flatten those into one “rulebook,” you miss how the sport actually functions.
Traditional vs Modern Lethwei Fighting Rules
Traditional Lethwei (“ရိုးရာ” Yoe Yar rules) comes from Myanmar’s village and festival culture, still visible during events like Thingyan. These rules are deliberately minimal, but not vague.

- No weight classes
Fighters are matched visually rather than by scale. Officials look at height, bone structure, muscle density, and experience. The larger fighter may also be matched despite the difference in physicality if it is deemed to be acceptable. Such uneven and deliberate matches require more adaptability than fairness.
- No fixed number of rounds and time limitations
In some formats, there are indeed rounds, yet no specific time limit for them exists, and their lengths depend on the level of exhaustion of the fighters. In other cases, like prolonged tournament rounds, they have no time limit at all, going on until an outcome emerges. Time is not the governing constraint. Outcome is.
- Bare-knuckle striking with minimal protection
Fighters wrap hands and feet using gauze and tape. No gloves are used in lethwei. This changes technique. Fighters punch more selectively to avoid injuring their hands, which increases the frequency of elbows, clinch work, and headbutts.
- All major striking and clinch Lethwei techniques allowed
This includes punches, kicks, elbows, knees, and headbutts, along with sweeps, throws, and takedowns. The clinch is not a neutral position. It is a primary offensive phase.
- No point scoring system
There are no judges tracking scores. Only referees and juries are present. A fight is not evaluated over time. It is resolved by a decisive event.
- Victory conditions are narrow and strict
A fighter wins only by knockout, stoppage, or opponent inability to continue. If both fighters remain standing at the end, the fight is declared a draw. This is not a fallback. It is the expected outcome unless one fighter proves clear physical superiority.
- Referee authority replaces detailed regulation
The referee can stop mismatches, call in the doctor, or end the fight if one fighter is clearly outclassed. This centralized authority substitutes for a detailed rulebook.
This system is coherent. It removes scoring ambiguity and replaces it with a single requirement: you must physically stop your opponent.

Modern Lethwei (post-1996 reforms) modifies this structure to support organized competition, especially through the Golden Belt Championship system.
- Introduction of weight classes (typically nine divisions)
This was added to improve fairness and allow structured matchmaking across a national pool of fighters.
- Standardized rounds and timing
Fights are usually 3 to 5 rounds, each lasting 3 minutes, with 2-minute rest periods. This creates consistency for scheduling, broadcasting, and tournament brackets.
- Removal of certain recovery mechanisms
Prior matches permitted a fighter to recover for a long time after being knocked down. These recovery methods were eliminated during tournaments in order to avoid any delays.
- Addition of judges in specific formats
In matches with scoring, if there is no knockout, judges declare the winner of the match. This is due to functionality as a tournament, and not because of philosophical abandonment of the knockout.
- Defined scoring criteria
Aggressiveness, amount of effective hits, visible injury, and whether there is any bleeding – all factor into the judges’ decision-making process. These criteria favor fighters who push the action rather than control it passively.
- Knockdown count limits enforce cumulative damage
When a fighter is knocked down and cannot immediately get back up, the referee will begin counting. A count must reach at least 8. If a fighter is knocked down three times in one round or four times across the whole fight, the fight ends as a knockout. Four knockdowns across the fight also trigger a knockout. This prevents endless survival without consequence.
Modernization did not replace traditional logic. It layered structure on top of it so that competitions could produce winners consistently.
Referees, Juries, and Judges
Across traditional and modern lethwei formats, there are three types of officials, called “ဒိုင်လူကြီး” (Dine Lu Gyee) or just “ဒိုင်” (Dine), who oversee the fights and have the authority to determine the outcome of the fight.
Referees “ကြိုးဝိုင်းဒိုင်” (Kyoe Wine Dine) are present in every fight format. They are the officials that enter inside the ring during every match, and are the ones who monitor fights the closest. They can be in charge of determining the length of rounds, watching the conditions of fighters, enforcing rules in the ring, stopping the fight if necessary, and in some cases, even administering medical care. Depending on the format, matches can have one or two referees present in a fight.
Juries “ခုံဒိုင်” (Khone Dine) are also present in every fight format. They are the officials who stay outside the ring and can usually be composed of the announcer, fight organizers, authorities, experienced fighters and referees etc. They do not monitor a fight from within a ring closely like a referee would. However, they are considered the highest authority and influence on the fights, for example, they can order the referees to stop a fight.
Judges “အမှတ်ပေးဒိုင်” (Amat Pay Dine) are only present in fights with scoring. They are in charge of staying outside the ring, observing the fights, and giving scores to fighters based on a predetermined scoring system. In fights with judges, if no winner is determined by any other method (KOs, cuts, referee stoppage, doctor stoppage etc.) by the end of the fights, judges’ scores are used to determine the winner based on who scored the highest.
Types of Lethwei Fights
The rule differences become clearer when you look at the four fight formats, each built for a specific role.
1. Gya Bwe “ကြားပွဲ” (Novice / Community Fights)
Gya Bwe, directly translated to mean “in-between fight”, represents the most traditional and least formal version of Lethwei.
- Purpose
These fights exist for community engagement. They entertain, introduce new fighters, and act as an informal selection system for higher-level competition.
- Fighter selection
There are no registrations or weight divisions. Fighters volunteer, and officials assess them visually. Factors include physical build, toughness, and signs of experience. Some fighters may be rejected or redirected if mismatched.
- No judges scoring
Two referees are present in each fight. A jury also observes, but they do not score. They intervene only if necessary.
- Structure
Each round has no standardized time limit. Instead of using a clock, the referees determine how long 1 round is subjectively based on an “effective exchange of attacks”. 1 effective exchange of attacks is called 1 “လား” (Laar). 3 Laar makes 1 round. Each fight lasts 3 rounds total.
- Rotating round system
Instead of finishing one fight at a time where each match fights consecutive rounds, all bouts rotate. One pair of fighters complete one round, leave the ring, the next pair of fighters enter and fight, and this continues until it returns to the original pair of fighters to continue their subsequent round. This keeps the event flowing and allows extended recovery.
- Victory conditions
Knockout, stoppage due to injury or cuts, opponent quitting, or clear outclassing. If none occur, the fight ends in a draw.
Exposure to the community takes precedence over competitiveness in this structure.

2. Alan Lu Bwe “အလံလုပွဲ” (Flag Tournaments)
The Alan Lu Bwe, directly translated to mean “flag seizing fight”, is considered the pinnacle of traditional competition.
- A division system that ignores the rigid structure of weight categories
Fighters are placed in the appropriate division according to their size, experience, and reputation.
- Format involving tournaments with lottery pairings
Fighters draw lots to determine matchups, reinforcing fairness and unpredictability.
- Expanded format
Fights start with three rounds. The duration of each round is composed of 3 Laar, the same as a Gya Bwe. If no victor appears by the end of the third round, a fourth round commences without a time limit which only ends when a decisive result emerges. This is called fighting “ရေကုန်ရေခမ်း” (Yay Kone Yay Kham), literally translated as “until all the water is gone”, basically meaning until a fighter is absolutely drained of stamina.
- No scoring system
Like Gya Bwe, there are no judges. The fight must produce a winner through action.
- Unique counting ritual
When one fighter is knocked down, instead of a standard count, the standing fighter circles the ring and, upon arriving at their corner, performs a Lekkha Moun three times. After the standing fighter circles the ring three times total, if the downed fighter cannot rise by the end, the fight is over. This blends competition with ritual.
- High endurance demand
Tournaments usually last 3 days, but fighters may compete multiple times in a single day.
Alan Lu Bwe eliminates the possibility of a draw by design. If necessary, it extends the fight until one fighter breaks.

3. Sein Caw Bwe (Challenge Fights)
This is the dominant modern format in Myanmar.
- Professional matchmaking
Fighters are paired based on reputation, rivalry, and audience appeal rather than random selection.
- Standardized structure
Five rounds lasting three minutes each, with two-minute rest periods. Weight classes are not required; open weight matches are an option. This system seeks to be fair while maintaining traditional flexibility.
- No judges and no scoring
Despite modern structure, the outcome remains traditional. If no finish occurs, the fight is a draw.
- Streamlined officiating
One referee and a small jury oversee the fight, reflecting a mix of tradition and professional organization.
- Standardized counting
When a fighter is knocked down, the referee will count from 1 to 10. Each count lasts 2 seconds. The referee will count to at least 8, and the fight continues if the fighter can. If the referee decides the downed fighter is in no shape, the referee will count to 10 and give a loss.
During a single round, if a fighter is counted three times, the fighter is given a loss. During a whole match, if a fighter is counted four times total, the fighter is given a loss.
- Single ‘Special Rest Rule’ timeout
Each fighter can use one two-minute timeout between Rounds 1 and 4. This allows recovery from knockdowns or cuts. No timeout is allowed in the final round.
Sein Caw Bwe is where modern presentation meets traditional philosophy. It looks like a professional sport but still refuses to award non-decisive victories.

4. Amat Pay Bwe (Scored Tournaments)
This is the most modernized format, created for structured competition.
- Introduced during the 1996 Golden Belt Championship reforms
Designed to align Lethwei rules with international combat sports while keeping its identity.
- International weight categories
Fighters are matched up using an international weight category system. Each category will typically have 8 fighters, though the number could be more. The matchups are determined by drawing lots.
- Full judging system
Three or five judges score the fights. If no winner is determined during the fights, the judges’ scores are used to declare a winner. One referee and the jury are still present but they do not score.
- Clear scoring criteria
Aggression, effective striking, visible damage, and blood drawn are prioritized. Defensive point-fighting has limited value here.
- Strict round structure
Five rounds, three minutes each, with fixed two minute rest periods. No special resting rule.
- Knockdown limits enforced
Counting is included, and three counts per round or four total in a match still trigger a loss for the counted fighter.
- Tournament functionality
This system ensures winners advance, solving the draw-heavy problem of traditional formats.
Even here, knockouts are still preferred. Decisions exist as a backup, not the main objective.
The Golden Belt Context
The Golden Belt is the highest recognition in Lethwei, but its meaning goes beyond sport.
- Historical shift from informal recognition to formal titles
Before the 1990s, fighters built reputations through performance. There were no official champions. - Introduction of national structure
The Myanmar Traditional Sports Federation formalized competition, creating weight classes, tournaments, and a ranking system. - One champion per division plus an openweight champion
The openweight champion is considered the strongest fighter overall, similar to a pound-for-pound ranking. - Symbolic significance
Winning the Golden Belt connects a fighter to national identity, not just athletic success. It represents resilience, toughness, and cultural continuity.
The Golden Belt system did not replace tradition. It gave it a formal framework.

Basic Fight Rules
Number of Rounds
Modern Lethwei rules for fights follow a standardized structure, but that structure only exists because of relatively recent reforms tied to organized competition and the Golden Belt system.
- Modern formats (Sein Caw Bwe and Amat Pay Bwe) typically use 3 or 5 rounds, with 5 rounds being the norm for high-level fights. This structure allows promoters to schedule events predictably and lets tournaments progress without disruption.
- Traditional formats are far less rigid.
- In Gya Bwe, fights usually have three rounds, but the emphasis is not on the number itself. It is simply a practical limit for community events.
- In Alan Lu Bwe, fights begin with three rounds but can extend into a fourth round with no time limit if no winner is determined. That fourth round continues until a decisive outcome is reached.
- Historically, there were no fixed round limits at all. Early Lethwei bouts were governed by circumstances such as daylight, fighter condition, or the will of the organizers. The introduction of round limits came later as part of modernization.
The key point is that the round structure in Lethwei is not about pacing a contest for scoring. It exists to create opportunities for a finish, and when that fails, some formats simply remove the limit entirely.
Time Duration
Modern Lethwei uses fixed timing, but traditional formats treat time as flexible.
Modern fights:
- Three minutes per round
- Two minutes rest between rounds
This provides for a very common rhythm typical of boxing or kickboxing, making the sport easier to regulate and broadcast.
Traditional fights:
- Three to six minutes of each round; dependent on the intensity of exchanges and the stamina of opponents.
- There is no clock enforcement. The referees and jurors assess the end of the round based on a subjectively determined effective exchange of attacks called “လား” (Laar). 3 Laar makes 1 round. Each fight lasts 3 rounds total.
- Rotational system of rounds (Gya Bwe and Alan Lu Bwe) complicates time management further:
- Opponents finish a round, exit from the ring, and return for another round when their opponents are done fighting and resting.
- In effect, this incorporates the rest in the format of the tournament without using any kind of official corner system.
- Unlimited rounds in Alan Lu Bwe do away with time constraints at all: the fight goes on till there’s a clear winner, however long it might take.
Flexibility means that fighters have to adopt new tactics when it comes to stamina because now they do not know how long it will go on.
Explanation of the Lethwei Knockout Rule
The lethwei knockout rule is not just another rule. It is the whole basis that is used to construct other rules.
In order to win, a fighter must achieve:
- Knockout (KO)
The opponent is rendered unconscious or unable to continue within the count.
- Technical knockout (TKO)
Either the referee or the doctor decides to end the match in case of serious injury due to the presence of cuts or accumulated damage, or a fighter being clearly overwhelmed.
- Opponent withdrawal or inability to continue
Traditionally, there are three additional ways for a fighter to lose a fight. They are
* Retirement “ကြောက်ရှုံး” (Kyauk Shone)
* Deep cuts “ကွဲရှုံး” (Kwe Shone)
* Stamina loss “သက်လုံရှုံး” (Thet Lon Shone)
If none of these occur:
- In traditional formats and challenge fights (Sein Caw Bwe) → the result is a draw, regardless of who appeared to perform better.
This is a critical distinction. Lethwei does not recognize “winning on points” in its traditional logic. A fighter who dominates but fails to finish has not completed the task.
The Count System
To prevent endless survival, Lethwei rules uses strict knockdown limits:
- A referee counts to 10 times.
- A count must reach at least 8 for it to be recognized.
- Three knockdowns in a single round automatically end the fight as a knockout.
- Four knockdowns across the entire fight also result in a knockout.
These rules serve a specific purpose. They ensure that, despite repeated recoveries, a knockout can be inevitable because of the cumulative strikes received.
In some traditional tournaments like Alan Lu Bwe, the counting process can even take on a ceremonial form rather than a strict numerical count, reinforcing that the goal is not technical precision but clear resolution.
The Outcome of a Knockout
While Lethwei does not simplify the concept of a knockout, it has unique procedures for handling recoveries from a knockout.
- In Sein Caw Bwe (challenge fights):
- Each fighter is allowed one two-minute injury timeout between Rounds 1 and 4.
- This can be used after a knockout or when a fighter is heavily damaged.
- During this time, the fighter can be revived, treated, and assessed.
- If they recover, the fight continues.
- No timeout is allowed in the final round.
This forces a definitive ending. A fighter cannot rely on recovery when the fight is about to conclude.
- In Amat Pay Bwe (scoring tournaments):
- This recovery mechanism was removed during the 1996 reforms.
- The reason is practical. Tournaments require continuous progression, and extended recovery periods slow that down.
- In older traditional contexts, recovery could be even more flexible and extended, depending on the officials and the situation.
The effect of this rule is strategic. A knockdown in Lethwei does not guarantee victory. Fighters must go beyond scoring damage. They must prevent recovery entirely or accumulate enough damage to trigger a stoppage.
This is one of the clearest differences between Lethwei and most other combat sports. In many systems, a knockdown strongly influences scoring. In Lethwei rules, it only matters if it leads to irreversible consequences.

Striking Rules In Lethwei
Legal Strikes
Lethwei is often summarized as the “Art of 9 Limbs,” but that shorthand hides how fully integrated those tools are. Headbutts are not an optional addition. They are part of the same offensive system as punches, elbows, knees, and kicks.
- Full striking range is permitted
Fighters can use:- Punches (bare-knuckle under the bare knuckle fighting rules, with only gauze and tape)
- Elbows from all angles
- Knees in clinch and open space
- Kicks to multiple levels
- Headbutts, both standing and in the clinch
- Clinch fighting is fully offensive
Unlike sports where the clinch is quickly broken, Lethwei allows:
- Extended clinch control
- Sweeps and throws
- Off-balancing into strikes
- Close-range headbutts
This matters because headbutts are most effective at very short range. The rule set does not just allow them. It creates the conditions where they are practical.
- Bare-knuckle context changes weapon selection
Because fighters are not wearing gloves:- Punching carries a higher risk of hand injury
- Fighters rely more on elbows and headbutts in tight exchanges
- Guard structures are different, making head positioning more important
- Headbutts as a tactical tool
In practice, headbutts are used:- To open cuts, especially on the brow line
- To disrupt clinch control
- To break an opponent’s posture before follow-up strikes
This is not theoretical. In a system where cuts can lead to doctor stoppages, a well-placed headbutt can end a fight without a traditional knockout.
The result is a striking environment where distance collapses quickly, and positional control becomes as important as striking volume.
Illegal Moves
Despite its reputation, Lethwei is not unregulated. The difference is how rules are enforced.
- Actions that are specifically forbidden:
- Gouging eyes
- Biting
- Purposeful targeting of sensitive areas that may result in serious bodily harm beyond the competition element.
- Implications can be made using referee discretion
Rather than having a large set of technical fouls to refer to, Lethwei relies on the referee’s discretion to determine intention behind moves or danger involved. - Referee’s authority is central
The referee can:- End the match if it’s clear that one contestant is outclassed.
- Pause the match and have the ringside doctor check on injuries, particularly in case of deep cuts or heavy bleeding.
- Give warnings or intervene when necessary.
- Doctor intervention also determines a TKO
A technical knockout does not have to be based on the count of the referee. Rather, it is often the doctor’s assessment of whether there is any risk in continuing the bout.
Lethwei favors overt decisions and results over the enforcement of technicalities. Instead of preventing every possible foul through detailed regulation, it allows broad action but intervenes when safety is clearly compromised.
Lethwei Scoring System
How Winners Are Decided
The Lethwei scoring system is best understood as two separate models that exist for different purposes.
Traditional and Challenge Formats (No Scoring)
In traditional fights (Gya Bwe, Alan Lu Bwe) and challenge fights (Sein Caw Bwe):
- There are no judges and no point system
- Fights are not evaluated round by round
- A fighter wins only through:
- Knockout
- Technical knockout
- Opponent withdrawal or inability to continue
- If neither fighter achieves this → the fight is a draw
This has several consequences:
- Dominance without a finish does not count
A fighter can land more strikes, control the clinch, and appear clearly superior, yet still not win. - Draws are normal and culturally accepted
They are not controversial outcomes. They indicate that neither fighter proved decisive superiority. - Aggression is structurally rewarded
Since there is no benefit to “winning rounds,” fighters are incentivized to take risks to secure a finish.
In effect, the absence of scoring is not a limitation. It is a rule that forces a specific style of fighting.
Modern Scored Tournament (Amat Pay Bwe)
With the introduction of the Golden Belt Championship system in 1996, a scoring framework was added for practical reasons.
- Judges are introduced (typically 3 or 5)
Their role is to determine a winner if no knockout occurs, allowing tournaments to progress. - Criteria for scoring are very specific:
- Aggression: Who is initiating action and setting up exchanges
- Significant strikes: Not only quantity but also the quality of the impact
- Damage: Visible effect on the opponent, such as destabilization
- Bleeding: Cutting or visible blood drawn are considered
- Priority of knockouts remains
Despite having judges, achieving knockout is always preferred over the decision. - Knockdown rules remain the same
A fighter who gets knocked down three times in a round or four times during a match loses by knockout. - Structural necessity
Without judging, tournaments would stall due to repeated draws. The scoring system exists to solve that logistical problem, not to redefine the sport’s philosophy.
Key Tension Between Systems
The coexistence of these two systems creates a tension:
- Traditional logic: “If you didn’t finish, you didn’t win.”
- Modern logic: “If no one is finished, we still need a winner.”
Lethwei does not fully resolve this tension. It maintains both approaches depending on context. That is why the same sport can produce frequent draws in one setting and clear decisions in another.
Understanding that split is essential. Without it, the rules appear inconsistent. With it, they form a coherent system built around one idea: finishing the fight is the highest form of victory.

Practical Examples of Fights
Case Study Samples
Common Draw
Two fighters compete under a format such as Gya Bwe or a Sein Caw Bwe challenge fight. During three or five rounds, both land punches, exchange clinches, and take hits, but none gets knocked out or stopped.
- What takes place in this particular bout
- They utilize all elements of the Lethwei fighting style, including kicks, punches, knee strikes, elbow strikes, and sometimes head butts.
- Exchanges during the clinches feature attempts to sweep, but neither of them proves successful enough to gain an edge.
- Cuts might happen, but not severe enough for the doctor to intervene.
- The reason behind the draw
There are no judges to score the rounds. Regardless of how cleaner or technically better one fighter appears, this fact is irrelevant without a clear winner being established. - Cultural interpretation
In Lethwei, the fact that this match finished in a draw does not create controversy since both of them have shown their toughness and competitiveness.
Keynote:
It is possible for a fight to be tough, entertaining, and even clearly favoring one competitor while ending up unresolved.
Count-Limit Knockout
The fighter achieves consecutive knockdowns in quick succession.
- What happens during the fight
- Fighter A lands a clean strike on Fighter B, leading to a knockdown → 1st count
- Fighter B gets up and carries on
- Another knockdown from Fighter A occurs within the round → 2nd count
- Another knockdown occurs soon after
- Rule implementation
- Each knockdown must reach at least an 8-count
- When the third knockdown happens within one round, the bout stops automatically
- Why the fight ends now
Though Fighter B is still standing and trying to go on, the rules consider consecutive knockdowns enough evidence of overwhelming damage. - Alternate scenario
If knockdowns are spread across rounds, reaching four total knockdowns in the fight also triggers an automatic knockout.
Keynote:
There is no need for one spectacular finish in Lethwei. Accumulated damage is enough to end the fight decisively.
Extended Tournament Fight
This scenario typically occurs in Alan Lu Bwe (flag tournaments).
- What really goes on in the fight
- Fighters go through three rounds without a knockout or stoppage
- A declaration of draw isn’t allowed, rather, continuation is mandatory
- A fourth round starts without any time limit
- Dynamics of the fourth round
- Fatigue plays the decisive role
- Fighters relying on pacing in earlier rounds must get into ongoing action
- Clinching gets rougher with more headbutts and close-range strikes due to depleting stamina
- Resolution of knockdowns (traditional way)
- No counting is done
- The standing fighter performs a ceremonial act – they circle around the ring, and when they get back to their own corner, they perform the Lekkha Moun three times.
- This performance is done thrice.
- If the fallen fighter cannot stand up, then the fight ends there.
- Conclusion
Ultimately, one fighter is forced to surrender or collapse.
Key takeaway:
The structure eliminates any doubt by removing time limitations. If three rounds are not enough, the fight continues until someone physically breaks.
Modern Judged Fight
This occurs in Amat Pay Bwe, introduced during the 1996 Golden Belt Championship reforms.
- What really happens during the fight
- The fighters engage in combat through five rounds, each three minutes long
- Both strive for a knockout, and both miss
- Attacks involve hard punching, grappling, and efforts to do damage visibly
- Scoring process
In case there are no conclusions to be made, three or five judges score the fight on the following aspects:- Degree of aggression and forward pressure
- Quantity and quality of significant attacks landed
- Amount of damage visibly done
- Drawing blood
- Count constraints still apply
- If one of the fighters receives three knockdowns within a round or four within the match, the bout would be stopped as a knockout
- The judgement occurs only because neither fighter reached those thresholds
- Final verdict
Judges make their decision, declaring the winner of the bout according to the criteria above. - Why this system exists
In tournament settings, fighters must advance. Without judging, repeated draws would halt the bracket.
Keynote:
This is the only context where performance without a finish can produce a winner, but even here, the criteria are designed to reward fighters who attempted to end the fight rather than control it safely.
General Observations
In all four examples, the same observation stands true:
- Fights can go unsolved in common formats rather than forcing winners
- Structural rules like knockdown limits enforce eventual conclusions
- Some formats eliminate time restrictions to ensure outcomes
- Modern systems resort to judging only when competition logistics require it
Each case is not an exception. It is a different expression of the same underlying principle:
A fight is meant to be decided by physical consequence, not by interpretation alone.
FAQs About Lethwei Rules
Why are draws common?
Because the system requires a decisive finish. Without one, neither fighter has proven superiority.
Why allow headbutts?
They are integral to the system, especially in a bare-knuckle environment where close-range tools become more important.
What changed in modern Lethwei?
Weight classes, judges, and structured rounds were added to support tournaments, particularly through the Golden Belt system.
Is the Golden Belt just a title?
No. It represents national recognition and cultural significance, connecting fighters to the history and identity of Myanmar.
Closing Observation
Lethwei is not trying to be a balanced sport in the conventional sense. It is trying to answer a specific question with minimal ambiguity.
Traditional formats ask:
Who can endure and impose their will until the other cannot continue?
Modern formats add a secondary question:
If neither can finish, who came closer under pressure?
The rules, across all variations, are built to answer those questions as directly as possible.
