Twisted four (version 2)

Twisted four  

Just like the bent four, this eye shape makes a group alive. The points 'a' and 'b' are miai: Black can always play one of them to make two eyes.

Just like the bent four, twisted four is affected by the special properties of the corner although the implications are not quite the same. See twisted four in the corner.
