side

This sacrifice is a side technique, playing an attachment, aiming at sacrificing it in favour of 1, or mostly 2 forcing moves.

B1 is the attachment, and if White accepts the invitation to capture, Black cuts and forces with B5 and B7, getting an influential position towards centre and below.

[Diagram]

resistance

White can avoid a second forcing move by capturing immediately, but then invites a ko which is difficult to bear.

[Diagram]

peacemeal

The outside hane of W2 denies the sacrifice. Connections at a and b may follow, depending on how lightly the area will be treated.
