Very Artificial Problem / Attempts

Confused: I don't really have a solution for the problem, but it looks to me, that by enclosing the corner, Black has a fair fighting chance to capture. Whatever I try here either ends with White getting captured or in a big mess I can't read properly.

Enclosing the corner  

Illich: I think White runs away like this:
(Black a leaves too many cutting points, Black b is slow, White runs with c - is that right?)

Enclosing the corner  

Niklaus: At a is the hardest resistance Black has to offer. But I still found a way for White to escape. I hope someone can find some better black moves, so I can finally find peace :)

At 'a' is hardest to disprove

Continuation 2  



Herman: I can't find better black moves, but White can escape much more easily and without the ko:

White escapes or lives  

The cutting points at a and b mean that White will either capture the marked stone or the stone 2.


Illich: My idea:
(Can someone disprove it?)

Disprove  

Niklaus: Plays at 1 or a escape easily.

Proof?  

It is not so certain --Dieter

Add Black's answer?  

But what about the double-atari waiting in the wings? Maybe White should make a-b exchange first? --TakeNGive

What about this?  

What if White plays 3 immediately? Niklaus

What about this?  

You mean 4 here --dieter


Herman: You can repeat this pattern for some time, and along both edges, but in the end it is too weak and White will break through as you can see below.

There may be variations on this pattern that work though; I'll see what I can come up with.

Breaking the pattern  

Niklaus: To me that pattern seems strong enough (at least I think I found a refutation for Herman's breaking sequence.)

[Diagram]
Can White really break the pattern?  
[Diagram]
Maybe we finally got the solution  

Herman: What if White first extends the pattern along the top as well? Now Black can't make the atari at a required for the above pattern breaker.

Herman: Maybe a pattern like this one will work:

Repeating pattern number 2  

If White plays 9 at 10, Black plays at 9, locking White in. White has then created one potential eye (half eye). Even if she does the same along the top, two potential eyes are not enough (one will be destroyed), so a pattern like this might work. This one still seems too weak (Black can break out again with multiple atari threats).

Jasonred's Attempt?  

Jasonred I don't see how I have a hope of getting this if stronger players haven't but... I shall try nonetheless... My attempt answers a with b and c with d. If he tries e I answer with a.

unkx80: What about White 1?

Jasonred : Dunno! I'd personally attempt x or y, and then it becomes too confusing for me thereafter, can't read anymore. (mind you, I DID realize that cutting this was gonna end me up with problems... I'm guessing that, after x/y, the continuation is either b or d, and then I have to capture 1, and then it turns into some complicated sequence?

unkx80: Either way, after White 1, b and d are miai.

Jasonred : Obviously I understand miai in a different way from you... if I answer at x or y, how are b or d miai? I thought miai is where, if I play at b you play at d, and vice versa? Anyhow, here's my continuation, since you state no preference between b and d...

Does this sequence work out? I think that black captures here, but I get the feeling I might be missing something highly obvious...

Jasonred's Attempt?  

unkx80: These two diagrams are what I meant. =)

Krit: I feel that the marked black stone is a must, in this position. if A doesn't work it might be B, C or D

[Diagram]
The net is work.
