"Iwamoto maintained that he didn't need to add a stone at A, because he had more ko threats than White. According to the Nihon Ki-in rules promulgated the following year, players had to eliminate possible kos at the end of the game, but at this time there was no official set of rules. The game was a win for Go Seigen anyway, but since Segoe, the referee, could not resolve the dispute, the Yomiuri published the result as 'White won by 1 or 2 points'. Several days later, it transpired that a Nihon Ki-in committee set up in Shusai's time had drawn up a byelaw that agreed with Iwamoto's interpretation, so the official result became a win by one point."
