Kanazawa Problem 75 / Solution

Sub-page of KanazawaProblem75

Main line: HashimotoUtaro
Variations: Dieter

Main line

By the way, W5 is the famous move Sai immediately spots at a children's tournament in HikaruNoGo chapter 3.

[Diagram]

Continuation

If Black protects his stone, White captures three to make an eye.


Variations

[Diagram]

Variation at 6

If Black destroys an eye at B1, White surprisingly makes one at W2.

[Diagram]

Variation (ii) at 6

If B3 here, W4 connects and captures because of shortage of liberties.

[Diagram]

Variation (iii) at 6

This way variation (i) still holds its own.

[Diagram]

Variation at 4

Maybe this is a ridiculous variation but I couldn't help wondering what happens when Black takes that marvelous 1-2 point himself.

[Diagram]

Variation at 2

Anyone?

Nando: Well, I gave it a shot and couldn't find a way to unconditional life for White after B2 in this diagram, my best result being ko.

JoelR: After working on this problem a couple of nights and missing some lines, I showed it to my boss, who is 3dan. He was able to finish it off. For now, I'll put the analysis at /Varation.



By the way Dieter, I totally agree with what you said at the bottom of the tsumego page. I figured a lot of variations starting with that diagram, and although I didn't succeed in solving the problem, I feel that I've learned quite a lot about shape and the special properties of the corner.
