Black first

Black hits the shape point

B1 hits the shape point. Now a and b are miai for connection and the two white stones are in atari. White barely lives.

HolIgor. Note that I've seen this diagram in the Kobayashi Izumi book. At least, her face was on the cover. So, while this kind of move might be obvious, she considered it important enough. I reproduce it from memory and I am to be blamed for the mistakes.


Isn't B1 in that figure also known as an eye-stealing tesuji?

Good for Black

Bill: Black can be satisfied with this result. (Assuming the ladder works.)

Not so good for Black.

W6 at black+circle.

Black attacks strongly with B7 and B9, but W10 is tesuji.

[Diagram]

Not so good for Black (ii).

W10 at W6.

White's throwin, W6, makes a ko which White takes first.
