Consolidating frameworks

[Diagram]
Black broadens the framework

This is from a game between kyu players (game 83 from the Go Teaching Ladder). When Black played 1, White invaded deeply with 2. This threatens to use the marked white stone, for example by White a, Black b, White c.

Kim's suggestion

According to Kim Seong-june 6d, Black 1 to consolidate and control the aji of the marked white stone is better. If White 2, Black is content to build up with 3.



[Diagram]
Kim's suggestion (2)

The preceding plays were Black 1 to White 6 shown here. Kim feels that these kikashi should not have been played: Black a immediately is better. This is an example for use of kikashi to build up frameworks.



Another example, this time from pro-level opening theory.

[Diagram]
A known opening

Black 1 is an idea for building a mini-chinese formation later, at a, with an order of play that doesn't allow White to pincer. White 2 is a typical wedge, and by the time of White 10 she has a strong group usefully placed between two black frameworks.

Consolidate the corner

In most cases Black now plays at 1 here, rather than at a (the latter has been tried by Mok Chin-seok, though). There is plenty of corner aji at b; considering the effect of that combined with White's strength above, Black prefers to secure the existing framework, rather than expand it.
