Hanging connection to the second line as good shape
    Keywords: Shape

[Diagram]
Diag.: Good shape

Black 1 here is a hanging connection, designed to induce White's atari play at a. After that Black will have good shape - just one cutting point; if Black 1 is at a, potentially an overplay, then Black has two cutting points, which makes it quite hard to kill White (but see Enclosure Josekis Query 2).


[Diagram]
Diag.: Tenuki joseki

This is a tenuki variation that is common in practice (NB there is a ladder involved). Black 10 makes good shape.


[Diagram]
Diag.: Continuation

White 1 to live in gote is normal. White at a instead lives in sente: but Black becomes thick, since capturing the stone at a is later going to be sente for Black, and the ladder aji of a white cut at b disappears.
