[Diagram]
Diag.: Black to live

Black 1 is the VitalPoint. It clearly makes one eye at the circled point, and White won't prevent another eye left of 1.


[Diagram]
Diag.: Main line

[Diagram]
Diag.: Continuation 1

Note what a difference an extra white stone at A would make.


[Diagram]
Diag.: Continuation 2

Again, an extra stone at A would make the difference.



Once the VitalPoint has been played - 1 in the main line - the rest is not so difficult anymore. Finding that point is the main challenge here. Let's have a look at how things can go wrong.

[Diagram]
Diag.: Failure 1a

One is tempted to cover the two space gap with a move like Black 1 here. However, White strikes at the VitalPoint. If 5 at 8, then 6 at 5.


[Diagram]
Diag.: Failure 1b

This results in ko.
