sequences, is also attributed to him; as is the strategy of amashi. In playing Peichin Hamahika from the Ryukyu Islands, in 1682, he gave a practical demonstration of his theories, winning easily when giving a four-stone handicap. This game is a textbook piece and is still frequently cited. (The first game he won by 14; the second game on the same day was also recorded and he lost by a small margin, which may naturally mean that he had nothing to prove and was being diplomatic.) In the field of joseki, he innovated with the three-point low pincer, a more strategic play than the two-point low pincer favoured in particular by the players of the Yasui house. Pupils He taught Ogawa Dōteki, Sayama Sakugen, Hoshiai Hasseki, Kumagaya Honseki, and Kuwabara Dōsetsu. All but one died young, in their early twenties, and the Honinbo house faced a period of rebuilding. Dōsetsu became the Inoue house head. The young Hon'inbō Dōchi carried on the tradition.
