Shimamura Formation

Shimamura Formation  

The Shimamura Formation is the combination of the left Black shape with black+triangle. The common nature of B1-B5 joseki (see 4-4 point low approach low extension, slide, 3-3) allows for the formation to be easily made, thereby leading many professionals to research the position.

Sugiuchi Masao v. Chen Zude, 1963-09-27  

The first use in modern professional play was by Sugiuchi Masao, in 1963. Several years later, in 1975, Shimamura Toshihiro played it in a game with Kudo Norio. In 1978, he played it once more, and since then it has become known as the Shimamura Formation

The formation is discussed in Charles Matthews [ext] Fuseki on Your Side Part 7.
