Main line: Hashimoto Utaro

[Diagram]
Main line

After W1, both a and b, and c and d, are miai for life.


[Diagram]
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 W5, if Black connects at a, White captures three stones to make a second eye .


[Diagram]
Follow-up (ii)

It would be a mistake for White to answer B2 at a (next diagram).


[Diagram]
Mistake in the follow-up move

Black turns the corner into ko with the throw-in at B6.



[Diagram]
Wrong (i)

The 1-2 point is not the right spot to make life for this group. After the sequence to B9, Black throws in at W8 to leave White with a big eye.



[Diagram]
Wrong (ii)

Descending with W1 is also wrong. Black plays hane at B2, making miai of a and b for the kill.



[Diagram]
Wrong (iii)

This W1 may be the hardest one to refute. After B6, White can't play at a because of shortage of liberties. If she captures at b, Black plays at a himself to make the eye false.



[Diagram]
Wrong (iv)

White at W1 here, gives the same result as if White played w1 correctly at W3 here, but errs with her second move, by answering B4 at W1 (see earlier diagram). White lives in ko, which is not good enough.
