On March 19 and 20, the 7th(final) game of 56th Osho-sen between Osho Habu and Challenger Kisei Sato was held at Island Sado in Niigata prefecture, Japan. As a result of Furigoma, Habu was a Sente(Black) player and he won the game in 111 moves. He defended the Osho title and he has got entitled to be 2nd permanent Osho following to 1st Ohama since he has 10 terms of the title with this victory. Congratulation on Habu's great achievement You may replay the game here.
The diagram above is the resignation diagram when Habu dropped his kNight on 6e. After the diagram, Gote(White, upper side of the diagram)'s King will be forced to be mated. The possible variations I think are as followings;

There might be more variations. But Gote's king would be mated in any case
