On July 14 and 15, the 1st game of 49th Oui-sen 4-win match between Oui Fukaura and Challenger Yoshiharu Habu took place at Hokuten no Oka in Abashiri City of Hokkaido. Habu became Sente player this game as a result of Furigoma and he won it in 97 moves. The opening strategy was itteson-kakugawari(Bishop exchange with Gote's one move delay). It was a very close game until the end.
