Life In 19x19

Thanks! It just a bit confusing cause later in the book at other examples the author uses "white/black is alive in seki".

I think the topic can be closed now. Thanks again for the replies.

Thanks for the answer. Then it is just an error in the book? Cause at the end of the explaination of Dia 4 the authos says "white is alive", and not "white is alive in seki".

Greetings,

I have a question about one of the diagrams from the book of James Davies - Life and Death.

Dia4 on the pic below. Why is why alive? Doesnt white need to capture the 3 black stones inside in order to try to make 2 eyes - meaning capturing 3 stones is a dead shape?

Or black must first ...
