Status

[Diagram]

Unsettled.

The status of this group is unsettled.



White first

[Diagram]

Solution.

W1 kills easily.



Black first

[Diagram]

Solution.

B1 is the easiest way to live. If W2, then B3, and White cannot connect back the W2 stone.

[Diagram]

Solution.

B1 here is also a solution, but has quite a number of variations. If W4, then B5 connects, and after B7, a and white+circle is miai for life.

[Diagram]

Solution.

For W4, B5 will capture the two White stones directly. Again, a and white+circle are miai for life.

[Diagram]

Solution.

W4, W6, W8 aims at shortage of liberties. But after B7 and B9, the problem is solved, with white+square and white+circle being miai.

[Diagram]

Failure.

B1 is not a solution. The reason is that W4 is an atari.

[Diagram]

Failure.

This results in a bulky five.
