Black first to live

KarlKnechtel: This is the best I can do right now... Black already has one eye, and the only plausible way to make a second is by capturing. B1 is a natural way to start - anything other than W2 allows B1 at two to capture something and make the eye.

Black first to live

B3 is double atari, and connecting still leaves White in atari. So White elects to save the larger group of stones here.

B5 plays atari again, starting a ko. If White chooses to connect instead (at W6), B7 puts the pressure back on.


Nando: Good try, but there's a better way to get life (without ko)

Black first to live

B1 is the key. White has no choice but to connect at W2. Then, B3 gets the second eye because of the cutting point at a.

White can't destroy the eye

With the sequence up to B9, Black captures White's group.

alive

So, White must connect and Black then ensures life.


What about this?

[Diagram]

black kills?

Actually, B is dead in gote, being unable to fill the circled point. B fills, W fills, B can't atari while W can.
