Leather Scroll Problem 99 / Attempts

[Diagram]

Failure (white can't approach, and dies)

[Diagram]

Futile black resistance (black dies)

[Diagram]

Solution = Ko

Tapir: After B4 White's only choice not to end up similar to the first diagram (lacking liberties to approach, the black eyed group) is the ko. Black takes first.

[Diagram]

better B2 ?

hhw: Wouldn't this B2 revert back to the first diagram?

tapir: Indeed. Why I always make up non-working sequences. :(

[Diagram]

attempt, W7 at W3, B8 at W1

hhw: This seems pretty convoluted, but looks like it works. Result is ko.

tapir: Seems to work. W7-B8 are not needed imo, W7 at W9 directly, or B8 at a is easier to see, and still the same ko.

[Diagram]

doesn't work (W11 at W7)
