Unconditional Life
Difficulty: Beginner
Keywords: Life & Death, Go term
Jan: I found I needed the following definition to understand Benson's Algorithm. A group of stones is said to be unconditionally alive if it can never be captured, even with the opponent playing against the group as many times as he wants. Examples:
No matter what White tries against this group, it can not be captured.
This group, although it is normally considered alive, can be captured by White - by playing at 'a', 'b', 'c' and 'd' for example. jvt: Benson's terminology is confusing: unconditionally alive usually means alive without ko in Go literature.
