Early career

Cheawchan was born on April 8, 1970 into a family 7, consisting of his parents and 4 brothers in Phra Pradaeng district in Samut Prakhan province. Although he was disinterested in Muay Thai, his father forced him to become a fighter like all of his brothers. His father, an ex-Muay Thai fighter, trained Kaensak and his siblings. He adopted the ring name of Kaensak Taputhai and had his first fight at the Samrong Stadium. Despite winning the fight for a purse of 200 baht, Kaensak was not happy with fighting, even wearing shorts that were embroidered with the phrase "ผมถูกบังคับ" ("I was forced").^[1]

Kaensak's father continued to force him to fight around 50 times out of the Taputhai gym until he became a "rising star." He was initially a Muay Khao fighter (knee fighter) at this time. In 1981, his father wanted him to join a better Muay Thai gym, hence Kaensak was sent to the prestigious Sor.Ploenjit gym which was owned by Thai millionaire Sathien Sathiansut. At 15-years-old, Kaensak would begin training under the famous Gimyu Lerkchai, a top trainer of the various Sor.Ploenjit fighters as well as Lakhin Wassandasit.^[2] Kaensak would fight dozens of times in various venues until he won the Littleweight championship (80 lbs) at the Karunniwet Stadium in Chonburi province.^[1]

Fighting style

After training at the Sor.Ploenjit gym, Kaensak became well-rounded and explosive Muay Femur fighter meaning that he was a rope-a-dope fighter with fast and powerful defense. Muay Thai fighter and journalist Sylvie von Duuglas-Ittu, who has trained with dozens of elite golden era fighters including Kaensak, notes that his style was unusual compared to most other fighters of his time. He excelled at punching and kicking, was adamant about having an immediate response to every one of his opponent's techniques, and kept his opponents busy as much as possible. He would find or force openings for him to reliably land strong kicks to the body, as well as being able to throw powerful punches. The foundation of Kaensak's style was to turn protective techniques into offensive attacks. The amount of skill he had in combination with his unusual style led to him being praised by various golden era fighters, with Kaensak repeatedly appearing in the lists of top 5 Muay Thai fighters by renowned golden era fighters.^[3][4]

Owing to his fluency with knee fighting that he honed before transferring to the Sor.Ploenjit gym, Kaensak did not lose to Muay Khao fighters (knee fighters) by using a wide variety of both inside and outside techniques to prevent clinches and to cancel knee strikes. Most notably, Kaensak's trilogy against "The Vampire's Knees" Lamnamoon Sor.Sumalee wherein Kaensak shut down and controlled the tall knee fighter^[5][6] were considered top-of-the-line matchups. In addition, Kaensak scored a draw and a victory against "The Heartless Knee Striker" Langsuan Panyuthaphum.^[7]

Elite career in Bangkok

In 1989 Kaensak would enter the peak of his career by earning Lumpinee and Rajadamnern stadium titles simultaneously within the same weight class, becoming one of the handful of fighters who were able to do so. He ended the year with a 9-0-1 record for which he was given the most prestigious and respected title in Muay Thai: The Sports Writers Association of Thailand Fighter of the Year. Kaensak's peak continued into 1990 and he won the Fighter of the Year award for a second time, becoming the first nak muay (Muay Thai fighter) in history to win it for 2 consecutive years. In 1991, Kaensak would receive a purse of 380,000 baht, making him the highest paid athlete of the golden era of Muay Thai.^[7][8] In comparison, the usual purse of elite fighters was 100,000 baht and it was rare for one to earn 200,000 baht or higher.^[9][10]

As for his final fight of 1990, he was matched up against "The Sadist" Taweesaklek Ploysakda in Rajadamnern Stadium. Both fighters presented their usual styles, using powerful stikes of wide variety as Taweesaklek was a Muay Bouk (well-rounded pressure fighter) and Kaensak was an explosive Muay Femur. Kaensak was knocked down by a right cross in the 2nd round, prompting him to become aggressive and to use powerful low kicks; at the time Kaensak would also be known to be one of the strongest low-kickers in the Thai circuit. In the 3rd round, both fighters would use powerful low kicks against each other while Kaensak was pressing forward with punches. Taweesaklek was worn down by the low kicks and got knocked down by Kaensak's boxing in the 4th. Kaensak would win the fight by a large margin. This fight was Kaensak's favorite memory from his fighting career,^[7] in addition several newspapers and TV stations including Thairath and Channel 7 would label this fight as the 1990 Most Brutal Fight of the Year.^[8][11]

To determine who was to win the 1992 Fighter of the Year award, Jaroensap Kiatbanchong was matched up as the underdog against Kaensak in December 1992 with the Lumpinee junior bantamweight championship (115 lbs) at stake. Jaroensap won the fight on points and earned both the championship title and the award.^[12]

Kaensak and "The Earth-Shattering Left Kick" Singdam Or.Ukrit were matched up in 1993, the most significant year of Singdam's career. In the 2nd round, Kaensak knocked down Singdam with a right hook, and less than 20 seconds later Singdam knocked down Kaensak with a left hook and landed a right hook as Kaensak fell. Kaensak would fight hard for the rest of the fight but so did Singdam. Singdam ultimately won on points and achieved one of two biggest wins of his career.^[13] Both fighters would be awarded the 1993 Sports Writers Association of Thailand Fight of the Year.

Afterward, Kaensak would go on to continue fighting elite competition such as "The Master of Masters" Karuhat Sor.Supawan, Lamnamoon Sor.Sumalee, and "Samart 2" Chatchai Paiseetong. Kaensak was praised for his excellent defensive performance against Lamnamoon's clinches and knees and was also able to defeat the highly skilled Chatchai while he was still in his prime. Kaensak also secured victories against Nungubon Sitlerchai and Hansuk Prasanthinpanomrung.

From 1994 and onwards, Kaensak would begin to lose more often than usual as he went from fighting between 115 to 118 lbs to fighting as high as 125 lbs.^[14] Despite this, he would almost always be wearing red shorts which in the Thai circuit meant that he was the bettor's favorite.

Kaensak's nickname Yod Muaythai Song Por.Sor. (ยอดมวยไทย 2 พ.ศ.)^[5] translates to "The Two-Time Fighter of the Year," a nickname that would also go to Anuwat Kaewsamrit who is the second Muay Thai fighter in history to win the Sports Writers Association of Thailand Fighter of the Year for 2 consecutive years. Kaensak's victory against Langsuan Panyuthamphum as well as both of his fights against Taweesaklek Ploysakda were considered his best fights. Kaensak was matched up against Saenklai Sit Kru Od but they did not fight. The most difficult opponent Kaensak ever faced in his career was a fighter named Samart Lookindia, a fighter that Kaensak faced 4 times before he transferred to the Sor.Ploenjit gym. Samart defeated him in all 4 fights.^[1][7]

Retirement and later years

After losing to one of Superbon Banchamek's predecessors Baiphet Loogjaomaesaiwaree, Kaensak decided to retire from Muay Thai competition within Thailand in 1997. Just 6 Days after his final Bangkok Muay Thai fight, Kaensak would turn to professional boxing and won his first fight by KO. He would have a second boxing match in the next year and lost by points.^[7] In 2000 Kaensak moved to the United States where he became a Muay Thai instructor and judge. He came out of retirement multiple times fighting at a higher weight class against foreign champions Fabio Pinca and Tetsuya Yamato. He taught at AMA Fight Club in New Jersey, and now teaches at his own gym called the Kaensak Muaythai Gym which opened in 2020.^[15][16]

Kaensak cited Poot Lorlek, Vicharnnoi Porntawee, Dieselnoi Chor.Thanasukarn, Samart Payakaroon, and Chamuekpet Hapalang as his top 5 greatest Muay Thai fighters.^[4]
