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 a plan to immediately secure the rectangular six (respectively a derivation). But W2 threatens simultaneously connection to the outside (W4 at a) and killing the rectangular six (W4 at B3). B3, in the hope of creating seki with the additional point a, cannot work because of the two cutting points in Black's group.

[Diagram]

Failure.

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

[Diagram]

Failure.

This results in a bulky five.
