Xuanxuan Qijing Problem 43 / Attempts

[Diagram]

meuns?: 1 ?

[Diagram]

meuns?: White don't see 1

[Diagram]

[Diagram]

unkx80: Are you sure W4 at a doesn't live?

meuns? : Humm, i didn't see it.

[Diagram]


[Diagram]

tderz: W4 here looks promising ...

[Diagram]

tderz: ... actually, the shape of the 3 white+circle incites a different B3.
Then, you'll see that it still won't work.
Starting then from there ...


[Diagram]

Attempt

Dieter's attempt. If W2 at B3, B3 at W2. If W4 at B5, B5 at W4.

[Diagram]

Attempt

unkx80: How do you deal with this W2? Dieter: I'll have someone else answer that question.

MrTenuki: Would this work?

[Diagram]

Attempt

Dieter: Oops, another day, another view. I thought B3 at a works. By the way, Mr Tenuki, W6 at a lives.


[Diagram]

meuns?: Another idea, White 2 first move

[Diagram]

tapir: White lives with W4, no?

meuns?: I love my poor brain...

[Diagram]

B3 transponds to the same result, with the right move order?

Tapir: I don't see any possible resistance here to B3

[Diagram]

meuns?: Another idea, White 2 second move

Dieter: Wow, B1 was a blind spot to me. Strange things happen at the one-two point.

Tapir: W6 lives.

meuns?: Indeed, B3 is poor.

[Diagram]

meuns?: 3 ? + tapir: white resistance failing


[Diagram]

tderz: White 2 to resist!

tderz Dieter, inverse problem now, White doesn't want to die, and tries to resist.

[Diagram]

Dieter: White resists

Dieter: Ko


[Diagram]

tderz: different ko

tderz: usually the ko is shown in books in this way (an other way than given by Dieter here above),
perhaps because this ko lasts a bit longer ...
