There is a village in Buriram Province called Takotaphi — a small, unhurried settlement in the northeast corner of Thailand known as Isan, where the earth is famously dry and the rice harvests thin. The people who live there are Khmer-influenced Thais who speak three tongues — Thai, Lao, and Khmer — and carry the hard-muscled pragmatism of subsistence farmers. It is not, on the surface, a place that produces legends. Yet it is precisely here, in this unremarkable village a few hundred meters from a makeshift gym with two bags hanging from a tree and a mat as a ring, that Muay Thai found one of its most enduring champions.

Uthid Kodprakhon was born on January 1, 1984, the second of four children — three boys and one girl — raised by farmers who worked the area's rice paddies. His given name would eventually be eclipsed entirely by his ring name: Singdam Kiatmoo9, the Fierce Tiger of Khmer, the Black Lion of Buriram. But in the early 1990s, he was simply a boy from a poor farming family, watching his older brother disappear each morning down a dirt path toward a gym called Kiatmoo9 — named for the village district, Moo 9 (Village Number Nine), in Takotaphi. The gym had been founded by Mr. Sutjai Pumprakhon, a true lover of Muay Thai who initially opened it to train his own two sons, Joedja and Chanaphon.

Though both fought creditable careers in Bangkok before choosing education over the ring, Sutjai's camp would soon outgrow any one family and become one of the most celebrated training institutions in all of Thailand. At nine years old, Uthid made his first fight. A year later, he followed his older brother into the Kiatmoo9 camp, adopting the gym name and beginning what would become a 25-year relationship with Muay Thai at the highest levels. His younger brother, Seuadam Kiatmoo9, joined him, eventually amassing over 300 professional bouts of his own. For the Kodprakhon boys, the rice fields remained a backdrop, a reminder of what life might look like without the sport. Boxing offered a different path — and Singdam walked it with singular determination.

Kiatmoo9 Gym was not glamorous. There were no sparring machines or air-conditioned weight rooms; the fighters trained in the open, in the humidity of Isan, jogging on paths that wound through rice fields and conditioning their bodies through the repetition-intensive traditional methods. But what the camp lacked in facilities, it compensated for with culture. Almost every fighter who trained at Kiatmoo9 came from Takotaphi itself — they had grown up together, knew one another's families, and trained with the fierce loyalty of a community rather than the anonymity of a commercial gym.

That tight-knit identity would define both the gym's champions and Singdam's own approach to the sport. Young Uthid — now Singdam — proved himself a fast study. He began accumulating regional wins at a precocious pace and secured his first belt at just thirteen years old, claiming the Isan regional championship at 36 kilograms. It was a sign of things to come. In 2001, aged 17, Singdam announced his national ambitions by winning the prestigious Toyota Marathon Tournament in the 115 lbs (super flyweight) category, defeating Kongdech Kiatprapat — the Channel 7 champion at 126 lbs — in the final. Beating a fighter from a heavier class to win an open tournament was no small feat; it announced Singdam as a prospect capable of punching well above his weight class.

By 2002, Singdam was ready for the biggest stage in Thai boxing. On a storied night at the Lumpinee Boxing Stadium — the cathedral of Muay Thai in Bangkok, where every serious Thai boxer aspires to compete — he defeated Orono Wor Petchpun to capture the Featherweight Championship of Thailand at 126 lbs. He was 18 years old. The victory triggered a cascade of recognition: later that same year, the Sports Writers Association of Thailand voted Singdam Fighter of the Year, one of the sport's most coveted annual honours. His rapid rise had the Muay Thai establishment taking full notice.

"He hit me so hard with a long knee in my stomach in round 4 it bulged a disc in my back and needed months of physio to manipulate it back." — Liam Harrison, recalling his 2015 fight against Singdam

To understand Singdam Kiatmoo9 as a fighter, one must understand the Thai taxonomy of fighting styles. Muay Thai classifies its practitioners broadly by their primary weapons and tactical tendencies: the Muay Mat favours punches and low kicks; the Muay Femur is the elegant technician; the Muay Tae is the devastating kicker; and the Muay Khao is the relentless knee fighter, a grappler who uses the clinch as a weapon and the knee as the instrument of attrition. Singdam was, at his core, a Muay Khao — but with the uncommon capacity to excel across multiple dimensions.

His signature was a thunderous right kick, a weapon so consistently reliable that it became synonymous with his name across Thailand's fight circuit. Coaches and fans would speak of his right kick the way boxing aficionados discuss a great jab: as both a scoring tool and a controlling mechanism that bent entire fights to his will. But Singdam did not rely on power alone. He was distinguished by a relentless forward pressure that herded opponents into the clinch, where his technical superiority in the grapple often proved decisive. Once locked in, his knees were weapons of attrition — methodical, grinding, cumulative. Opponents discovered, sometimes too late, that the clinch they had stumbled into was a trap. Beyond individual weapons, analysts praised Singdam for his ability to read opponents mid-fight and adapt his game plan in real time.

He was credited with an exceptional tactical intelligence — an almost encyclopedic understanding of Muay Thai's subtle scoring language — that allowed him to grind out decisions against elite competition who possessed more flamboyant techniques. His movement was economical, his defence pragmatic rather than flashy. He did not aim to dazzle; he aimed to dominate. It was a style built for longevity and championship-level consistency over spectacle, and it served him across five weight divisions across a career that spanned more than two decades.

The years between 2002 and 2014 represent the fullest expression of Singdam's domestic supremacy. During this period he fought almost exclusively at Lumpinee and Rajadamnern stadiums — the twin pillars of Thai boxing prestige — accumulating titles across multiple divisions while trading blows with virtually every significant Thai fighter of his era. In 2003, the Lumpinee Stadium recognised his consistent excellence by naming him Fighter of the Year for the stadium — a distinction awarded by the stadium itself rather than by a press association, and considered by many insiders to carry even greater weight for reflecting the judgement of the sport's inner sanctum.

By 2004 and 2005, he had added the Super Featherweight (130 lbs) championship at Lumpinee to his collection, defeating Samkor Kiatmonthep twice in succession to claim the belt. The same year, he also defeated the rising Yodsanklai Fairtex, a future all-time great, in a contest that demonstrated Singdam's ability to neutralise opponents whose technical profiles differed sharply from his own. It was also during this period that the great rivalry of Singdam's career was born. In 2005, he first met Saenchai PKSaenchaimuaythaigym — widely considered one of the two or three greatest Muay Thai fighters in history — and won. The victory was significant: Saenchai was already a prodigious talent, and winning that first encounter placed Singdam in the conversation with the sport's elite. Over the following decade, the two would meet ten times in total, contesting some of the most celebrated bouts in Thai boxing's modern era.

The final ledger — Saenchai six victories, Singdam four — tells only part of the story. Every contest was closely fought, each setting was major, and Singdam's four wins over a fighter of Saenchai's calibre remain a benchmark that few fighters in history can match. In 2012, Singdam elevated his career to its domestic apex. He won the vacant Lumpinee Lightweight (135 lbs) title on June 8, defeating Wanchalerm Uddonmuang by decision. A month later, he knocked out Watcharachai Rachanon to make his first successful title defence. Then, on September 8, 2012, in one of that year's most anticipated bouts, Singdam defended his Lumpinee belt against Saenchai himself — and won by decision, a result that generated significant attention across both Thai and international Muay Thai media. It was a statement performance, cementing his status as the reigning king of the Lumpinee lightweight division. He did not hold the belt unopposed.

Rivalries with Nong-O Sit Or (later Nong-O Kaiyanghadaogym), who would become ONE Championship's dominant bantamweight Muay Thai champion, produced multiple fights — some won, some lost — that kept Singdam perpetually tested. By 2013, he had reclaimed his Lumpinee Lightweight title in a rematch against Nong-O, then added yet another championship in 2014 when he captured the Lumpinee Super Lightweight (140 lbs) title and won the Toyota Marathon Tournament for a second time — defeating his old nemesis Saenchai in the tournament final. His four Lumpinee titles across three divisions remain a testament to a career built on sustained excellence rather than a single explosive moment.

For most of his career, Singdam's brilliance played out almost exclusively before Thai audiences. The stadiums of Bangkok knew him intimately; the international Muay Thai community knew him by reputation. That began to change around 2015, when the global promotion YOKKAO Boxing — one of the sport's premier international organisations — brought Singdam to its fight cards in Europe and Asia. His debut on the international YOKKAO circuit made an immediate impression. At YOKKAO 15, held in Bolton, England in October 2015, Singdam met Liam Harrison — the New Zealand-born, UK-based fighter widely considered the top non-Thai competitor of his generation at 65 kilograms — on Harrison's home turf, before a crowd that expected a hometown victory.

Singdam won by decision. Harrison's own subsequent account of the fight is perhaps more eloquent than any scorecard: he described it as one of the most painful bouts of his career, recounting that Singdam landed a long knee to his stomach in round four that bulged a disc in his back and required months of physiotherapy to treat. 'We were both in serious condition,' Harrison reflected, 'as we both absolutely smashed each other to bits.' The defeat on home soil confirmed what Thai fight insiders had long argued: Singdam's level was genuinely world-class. In 2016, Singdam made a significant life and career transition, relocating to Bangkok full-time to train at the YOKKAO Training Center, bringing his older brother and longtime trainer, Kru Petchdam, with him.

The move represented both a personal evolution and a formal change in affiliation: in September 2017, YOKKAO announced that Singdam would henceforth compete under the name Singdam YOKKAOSaenchaiGym, reflecting his integration into the stable that also included his old rival, Saenchai. The pairing of former combatants-turned-training-partners became a recurring subplot of the YOKKAO brand's storytelling — two titans of Thai boxing, once bitter adversaries, now refining the next generation side by side. Singdam's most celebrated international performance came on July 27, 2019, in Dublin, Ireland, at YOKKAO 41-42 — the promotion's first-ever Irish event, held at the National Basketball Arena before more than 2,000 fans. Headlining the card against Craig Coakley, Ireland's top fighter and a KO specialist fighting in front of a fervently partisan home crowd, Singdam competed for the WBC Muay Thai Diamond Super Lightweight World Championship.

The WBC Diamond title is among the most exclusive in combat sports: prior to that night, only two fighters in history had claimed it at Muay Thai — Buakaw Banchamek in 2014 and Saenchai in 2011. Singdam took the fight at his own measured pace, neutralising Coakley's aggressive boxing movement with his signature right kicks and clinch-work. After five rounds it went to the judges, and Singdam emerged victorious by decision — becoming only the third fighter in Muay Thai history to hold the WBC Diamond belt.

"The small country camp has become one of the best camps in the country." — Siam Fight Mag, on Kiatmoo9 Gym

To assess Singdam's impact on Muay Thai, one cannot overlook his role within what has become arguably the most prolific championship-producing gym in the modern history of the sport. Kiatmoo9 Gym — that same barefoot Isan camp with the bags hanging from a tree — has, under the stewardship of Mr. Sutjai Pumprakhon, transformed itself into a national institution. Singdam was not merely its most decorated product; he was its standard-bearer, the fighter whose success drew attention to the village of Takotaphi and demonstrated that elite Muay Thai could be forged far from Bangkok's commercial training infrastructure.

The gym's honours list reads like a who's who of contemporary Thai combat sports. Panomrunglek Kiatmoo9 became a multi-time Lumpinee champion, Thailand champion, winner of the prestigious Isuzu Tournament, and the 2004 Lumpinee Fighter of the Year. His brother Petpanomrung Kiatmoo9 — known as 'The Professor' — went on to win the Glory Kickboxing World Featherweight title and multiple Thailand championships, becoming one of the sport's most technically refined competitive kickboxers. Wanchai Kiatmoo9 won both Lumpinee and Thailand championships. Rungnarai earned Lumpinee, Rajadamnern, and Thailand titles and was named Fighter of the Year in 2018.

Most prominently in the international arena, Singdam's nephew Superlek Kiatmoo9 — known as 'The Kicking Machine' and widely regarded as one of the greatest fighters of his generation — grew up watching his uncle fight and was inspired to begin training at eight years old. Superlek went on to win multiple Lumpinee and Thailand titles before joining ONE Championship, where he has competed at the highest international level.

The uncle-nephew relationship between Singdam and Superlek is emblematic of the gym's inter-generational transmission of excellence: the legends train the prospects, and the prospects carry the tradition forward. Singdam himself is listed as a notable trainer of Petpanomrung, Superlek, and Manachai Kiatmoo9 — all of whom have competed at world championship levels. His influence as a coach and mentor within the Kiatmoo9 family system represents a second chapter of his legacy, one that is still being written by the fighters he helped shape.

Singdam initially retired from professional competition around 2014, the year of his fourth Lumpinee title and his second Toyota Marathon championship. The decision was understandable: he had fought approximately 345 documented professional bouts — a number that staggers contemporary sensibilities but is not uncommon among Thai fighters of his generation, for whom volume of competition is part of the sport's cultural DNA. His body had been tested for over two decades at the highest level; the record of 277 wins against 66 losses and 2 draws was sufficient monument for any career.

Yet retirement, for fighters of Singdam's intensity, is rarely absolute. He returned to competition in 2019 for one final chapter: the WBC Diamond title fight in Dublin that placed his name alongside Buakaw and Saenchai in a select pantheon. It was, by any measure, a fitting capstone — not a comeback driven by financial necessity, but a deliberate pursuit of the one major distinction that had eluded his already extraordinary resume. That same year, in July 2019 — the same month as the Dublin triumph — Singdam co-launched an ambitious project to extend the Kiatmoo9 legacy beyond Thailand's borders.

Working with Mr. Gérard Cheung-Lung, a passionate Frenchman from Reunion Island, and in partnership with the original camp's owner Mr. Sutjai Pumprakhon, Singdam helped establish the Kiatmookao Singdum Saint Denis Gym — a modern, well-equipped facility built directly adjacent to the original Kiatmoo9 camp in Takotaphi, specifically designed to be accessible to foreign practitioners. The camp opened in July 2019, offering international students the rare opportunity to train in the same environment — and under the same roof — as Muay Thai's living legends, far from Bangkok's noise and pollution, jogging on paths through the rice fields where Singdam himself once ran.

The venture reflects a broader global appetite for authentic, source-proximate Muay Thai education — a market that has grown substantially as the sport's international profile has expanded through platforms like ONE Championship and YOKKAO's worldwide events. For foreign students seeking proximity to the sport's roots rather than a sanitised commercial experience, the Kiatmookao Singdum Saint Denis Gym offers something genuinely rare: access to champions in the village that made them.

Numbers are the bluntest instrument for measuring greatness in Muay Thai, but in Singdam's case they are at least impressive: 345 professional bouts, four Lumpinee titles across three weight divisions, three national Thailand championships, two Toyota Marathon titles, two Fighter of the Year awards, and a WBC Diamond world championship that placed him in the company of Buakaw and Saenchai — a credential virtually no other fighter in history can claim. He fought for over two decades against virtually every major name in Thai boxing across multiple generations, and remained competitive at the top level from his teens through his mid-thirties.

But the numbers understate the texture of his achievement. Singdam fought in an era of extraordinary depth in the Thai lightweight and super featherweight divisions, where the domestic circuit was ferociously competitive and a single slip could end a title reign within weeks. He navigated that environment with a tactical sophistication and physical consistency that produced longevity no fighter achieves by accident. His victories over Saenchai — four of them, spread across a decade — are not a statistical footnote; they are among the most significant results in the sport's modern era, achieved against a man many consider the greatest Muay Thai fighter who ever lived.

His legacy is also institutional. The Kiatmoo9 gym's dynasty is, in meaningful measure, his dynasty: he was the fighter who put Takotaphi on the map, whose titles drew the sponsors and the attention that allowed the camp to develop its infrastructure and attract the next generation of elite fighters. Superlek, Petpanomrung, Wanchai, Rungnarai — all carry within them some inheritance of what Singdam built.

That inheritance is generational, and it continues. For the global Muay Thai community — students, coaches, and fans who have come to the sport through its international expansion in the 2010s and 2020s — Singdam Kiatmoo9 represents a bridge between the sport's deep Thai tradition and its contemporary international appeal. He was, and remains, a fighter who could only have come from exactly where he came from: a dry-earthed, rice-farming province in northeast Thailand, from a gym named for the ninth village district, shaped by the discipline of a culture that has refined the art of eight limbs for centuries. The Black Lion of Buriram earned every title he holds — and in the memory of the sport he loves, they will not soon fade.
