Shape problem 3
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 in that figure also known as an eye-stealing tesuji?
Perhaps this is a better result? White does not lose the two stones in a snapback, like in the previous diagram.
A related shape problem.
Charles Matthews I wonder where this came from. I have just seen this in an old book:
unkx80: With or without , the first move is the same all right. ;)
Kosh Maybe it's better to descent in this shape
else (5 and 6 are miai):
Bill: Black can be satisfied with this result. (Assuming the ladder works.)
