Claim: Nobuaki Kobayashi (born March 26, 1942) was a Japanese billiards player who beat Raymond Ceulemans and Ludo Dielis.
Evidence: Nobuaki Kobayashi (小林 伸明, Kobayashi Nobuaki, March 26, 1942 – 25 November 2019) was a Japanese professional three-cushion billiards player and 2-time world champion. After placing 2nd to Belgium's Raymond Ceulemans three times (1970, 1972 and 1973) in the UMB World Three-cushion Championship, Kobayashi turned things around and defeated Ceulemans for the world title in 1974. A decade later, he won it again at the expense of Ludo Dielis.
