    Keywords: Problem

Main line: Hashimoto Utaro
Variations: Dieter

[Diagram]
Diag.: Main line

After White 1, both a and b, and c and d, are miai for life.


[Diagram]
Diag.: Follow-up (i)

For those who have solved or looked at the earlier problems in this series, this line of play will have become familiar. After White 5, if Black connects at a, White captures three stones to make a second eye .


[Diagram]
Diag.: Follow-up (ii)

It would be a mistake for White to answer 2 at a (next diagram).


[Diagram]
Diag.: Mistake in the follow-up move

Black turns the corner into ko with the throw-in at 6.



[Diagram]
Diag.: Wrong (i)

The 1-2 point is not the right spot to make life for this group. After the sequence to 9, Black throws in at 8 to leave White with a big eye.



[Diagram]
Diag.: Wrong (ii)

Sagari with 1 is also wrong. White plays hane at 2, making miai of a and b for the kill.



[Diagram]
Diag.: Wrong (iii)

This White 1 may be the hardest one to refute. After Black 6, White can't play at a because of damezumari. If she captures at b, Black plays at a himself to make the eye false.



[Diagram]
Diag.: Wrong (iv)

White at 1 here, gives the same result as if White played 1 correctly at 3 here, but errs with her second move, by answering Black 4 at 1 (see earlier diagram). White lives in ko, which is not good enough.
