[Diagram]
An orthodox development in modern go

This formation with three stones shows a balance of an enclosure, for territory, and a 4-4 point, for rapid development and influence.

Black has often adopted this as an opening since the late 1950s, and since about 1975, when Black's default opening became the 4-4 point, it has never been out of style for long.


[Diagram]
Ideal framework

Black by adding BC can get an ideal side framework.

Wedge to break up the side

Therefore White usually plays the wedge at W1 to limit Black's ambitions. White a is also a good wedge here; but White b allows Black a, working too well with the enclosure.

DaveSigaty: Where does this name come from? I did not know that it had a specific name before. Is it from Japanese?

Charles Matthews Just my idea. There are few specific names for fuseki or side formations, in the Japanese jargon. I'd be happy to call this hoshi, orthogonal komoku, kogeima shimari; but that's just my private dialect.
