Four spaces in a row, whether straight four, bent four or twisted four), are enough to live. We'll show for straight four:

[Diagram]
Diag.: Straight four.

If Black plays 1, White plays 2, and vice versa : 1 and 2 in the diagram are miai.


Five point eyespaces are alive except for the crossed five and the bulky five. Some examples:

[Diagram]
Diag.: A five-point shape that is alive

[Diagram]
Diag.: Another five-point shape that is alive.


Six point eyespaces are alive except for the Rabbitty six. An example is Rectangular six.


All eye shapes of seven points are alive.

[Diagram]
Diag.: Seven lives.

This shape is one that seems most likely to be killed, but after Black 1 the position is seki. See butterfly seven for the explanation.
