The life status is a fundamental notion
not only for go game
but also in geopolitics.
A group of stones with no liberties is captured.
And this means
that it’s dead.
It’s like a mat in chess.
But there is also
something which is even more important.
If a group has a means
to evade capture forever
then it’s called alive.
This is a new notion
which doesn’t belong to chess.
This possibility allows
a deeper strategy
and especially at the high level
which is similar
with Grand Strategy.
With life and death is possible
to study tactics
and by this way
to create a more robust strategy
at the higher level.
