There is Death in the Hane
Path: GoProverbs   · Prev: DonTFollowProverbsBlindly   · Next: SixDieButEightLive
    Keywords: Proverb

This proverb, "There is death in the hane", refers to the fact that the hane is a very common method of killing groups.

Example 1

[Diagram]
Killing by hane

For example, this black group (an L+1-group) can be killed with the hanes at 1 and 3. If Black blocks at a, it will turn Black's interior space into a dead bulky five. White can then kill Black with a placement tesuji at b.



Example 2

[Diagram]
Example 2

If Black tries to take at a, this does not gain an eye, and White can block Black's escape at b.



Notice that in the above examples, the hane stone is NOT defended when put into atari. Instead another hane or a placement follows. That is because the capturing the hane stone will get a false eye.
