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

Straight four.

If Black plays B1, White plays W2, and vice versa : B1 and W2 in the diagram are miai.



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

Six-point eyespaces are alive except for the rabbitty six. An example is rectangular six.
