Chayakorn Yoochumpon (Thai: ชยกร อยู่ชุมพล; born Suvit Yoochumpon Thai: สุวิทย์ อยู่ชุมพล; May 22, 1968), known professionally as Karuhat Sor.Supawan (Thai: คฤหาสน์ ส.สุภาวรรณ), is a Thai retired Muay Thai fighter. He is a four-time Lumpinee Stadium champion across two divisions who was famous during the 1980s and 1990s. Nicknamed "The Top Master", he is often regarded as one of the greatest and most talented fighters in the history of Muay Thai.
Suvit Yoochumpon was born on May 22, 1968 in Phon, Khon Kaen, Thailand. When he was around the age of 16, while playing a game of football, his friends encouraged him to participate in a nearby Muay Thai match as a fighter needed an opponent his size. Remarkably, despite having no training, he won the fight. Afterwards he'd be offered other fights and would be encouraged by his father to continue.
He had his first fights under the ring name of Siannoi Sitkru-O Kongnachai or Siannoi Sor.Ponsaming.[1][2] At this time he was a Muay Khao and Muay Femur hybrid which meant that he used a forward fighting, endurance knee style and an artful, defense-oriented style. He eventually stopped practicing the Muay Khao fighting style since its exhausting nature caused him to vomit during fights.[3] Karuhat, which translates to "castle" or "fortress", was the name given to him by his father. He'd fight in about 20 matches in Khon Kaen before moving to Bangkok.[4]
At 17 years old, Karuhat moved to Bangkok to begin training under Choi Malithong in the Sor.Supawan/Sor.Kanokrat gym, owned by Mrs. Suwimon Pinsathienket, under the name of Karuhat Sor.Supawan.[5] He started fighting so frequently that he could not visiting his home at all. On top of being the youngest fighter in the camp when he first joined, he was also tasked with doing chores in the gym.[3] Karuhat would become popular after a successful run in the suburban Bangkok stadiums at 100 lbs/45.36 kg and later attracted further attention of the Thai audiences by beating Nuengthoranee Petchyindee. He would later change his legal name to Chayakorn Yoochumpon.[4]
Karuhat made his Lumpinee Stadium debut in 1986 with a rematch against Nuengthoranee Petchyindee but lost by a close decision. After winning ten of his next twelve matches, including over elite fighters such as Toto Pongsawang, Panomrunglek Chor.Sawat, and Pairojnoi Sor Siamchai, he'd be given the opportunity to challenge for Hippy Singmanee's Lumpinee Mini Flyweight title in 1987. Both showcased their immense technical skill and lighting speed but Karuhat lost by a close decision.[6] After winning seven of next eight matches, including over elite fighters such as Kaensak Sor.Ploenjit and Pairojnoi Sor Siamchai, he'd be given another opportunity to challenge Hippy Singmanee for the vacant Lumpinee Light Flyweight title in 1988. They fought spectacularly once again but Karuhat lost by decision. Nevertheless, Karuhat's fame continued to grow and his talent prompted the Thai media to nickname him The Top Master (ยอดเซียน / Yodsian) among an array of other names referencing his skills. By this point he was already picked up by the Onesongchai Promotion which was considered the best of his era.[7] While the Sor.Supawan gym also housed other reputable fighters, Karuhat would become its most famous representative.[2]
Karuhat's cornerwoman and boss Mrs. Suwimon Pinsathienket was often shooed away from his corner during fights as women were heavily discouraged by superstition from touching the ring,[8] but she would get on top of it anyway in order to give him advice between rounds. She would corner for him during the most significant wins in his career, often pounding the ring as she told him what to do.[9]
His most preferred techniques were low kicks and elbow strikes.[10] Karuhat was proficient in fighting in both orthodox and southpaw so he'd often switch stances to create new openings and confuse his opponents.
Undeterred after losing his two title opportunities, Karuhat would defeat elite fighters such as Hippy Singmanee, Kaensak Sor.Ploenjit, Veeraphol Sahaprom, Oley Kiatoneway, Namkabuan Nongkeepahuyuth, and Paruhatlek Sitchunthong. He'd earn his third title opportunity against Pairojnoi Sor Siamchai, an elite Muay Khao fighter who was the victor of the record-breaking "Fight of the Century" held just months earlier, for the vacant Lumpinee Flyweight title in 1990.[11] Karuhat would use clinch and knee defense and counters to nullify and outscore Pairojnoi in the latter half of the fight. Karuhat won the bout and was awarded his first Lumpinee title.[12] Decades later Karuhat stated that this victory was his favorite memory from his Muay Thai career.[10]
Karuhat would also be the trainer of the twin fighters Chaiyai and Chailek Sitkaruhat.[13] The latter half of their ring names "Sitkaruhat" translates to "student of Karuhat." The twins would both go on to be elite Muay Femur themselves with Chaiyai earning a Lumpinee junior bantamweight belt.[14] Karuhat was matched up against the Dutch Mikael Lieuwfat for the World Heritage Muay Thai event in 1990. Karuhat won the fight while being unusually aggressive,[15] possibly pressured by the fact that the fight was being broadcast around the world.[4]
Around this time, Karuhat was also fighting at Bantamweight (118 lbs/53.52 kg) which was above his ideal weight class. The Onesongchai Promotion would force their top Bantamweight fighters including Karuhat to move up to Super Bantamweight (122 lbs/55.34 kg)[16] where he was able to fight Samkor Kiatmontep, Hansuk Prasathinpanomrung, and others. Despite fighting far above his ideal weight, Karuhat was still reliably winning against the most significant Super Bantamweight fighters such as Jaroensap Kiatbanchong, going so far as to win the Lumpinee Super Bantamweight title twice.
His 4-fight rivalry against Kaensak Sor.Ploenchit were considered the greatest fights in his career. In their third fight where he knocked down Kaensak with left cross,[17] Karuhat received a purse of 240,000 baht,[10] making him one of the few fighters who were paid above the 200,000 baht threshold. In their 4th fight Karuhat would give a difficult defensive performance against him, shutting down Kaensak's trademark counter-kicking style and consistently manipulating his balance.[18] Karuhat also gave excellent defensive performances against other elite fighters who excelled at pressure fighting such as Nongnarong Looksamrong[19] or the KO artist Veeraphol Sahaprom,[20] controlling their aggression and maintaining his distance well. Nungubon Sitlerchai, a Muay Femur fighter who knocked out both Samkor Kiatmontep and Wangchannoi Sor.Palangchai, singled out Karuhat as the most difficult opponent in his career; in the 3 bouts between them Nungubon was unable to win once.[21]
Although he belonged 2 weight classes below junior featherweight, Karuhat is considered by numerous Muay Thai practitioners as the greatest junior featherweight fighter of the 1990s as well as one of the most skilled fighters in the sport's history.[1] The Thai audiences referred to him by several nicknames such as The Fabulous Fighter, Aysian (The Talented), Yodmuay Atchariya (The Muay Genius), and Yodsian (The Top Master).[2]
Karuhat would no longer be in his prime in 1995,[4] the final year of the Bangkok portion of his Muay Thai career. While he took fewer fights in that year as a result, he was still able to secure the Lumpinee junior featherweight belt by elbow KO and beat Dokmaipa Por.Pongsawang as well as Silapathai Jockygym. After he took a hiatus for several years, Karuhat began fighting again despite not training seriously, resulting in him getting fewer wins and a KO loss against Alexei Pekarchyk.[2]
In the early 2000s, Karuhat opened the Sitkaruhat Muay Thai gym in Bangkok on top of being a trainer in various gyms in Thailand and abroad. He married Joy Pakamas, the daughter of his former boss Suwimon Pinsathienket. The couple had one son and later divorced.[4][10]
Saenchai was nicknamed "Little Karuhat" when he began fighting in the Thai circuit[22] and Prajanchai P.K.Saenchai has been compared to Karuhat due to their short stature as well as due to their combinations of low kicks, elbow strikes, and punches.[1]
