KyuExercise200/Attempts

Sub-page of KyuExercise200

I've tried to cover it yesterday with some great help from the folks of the KTL, do you think it's reasonable?

Proposed Solution

[Diagram]

It seems that either of these works (With an exactly identical following)

[Diagram]

One liberty ahead

[Diagram]

Reverts to the previous diagram


Some fail paths


Fail 1 - A more "relaxed" approach

[Diagram]

The need for an extra move against the eye here loses the semeai


Fail 2

[Diagram]

Approach ko for B

[Diagram]

W7 mistake

Big eye, too many libs

[Diagram]

W3 mistake

Too easy a ko

[Diagram]

B4 mistake


Fail 3

[Diagram]

Approach ko for B

[Diagram]

B2 mistake

W seems to live easily like this


Fail 4

[Diagram]

ressitance 1

ko again

[Diagram]

W5 mistake

B will get either a or b here and it's either lack of liberties for W or a big eye and a lost semeai

[Diagram]

B4 mistake

After W5 B hasn't got enough liberties to fight

[Diagram]

ressitance 2

ko again

[Diagram]

B4 mistake

Black is captured

[Diagram]

ressitance 3 (B2's a mistake)

hard ko

[Diagram]

Reason for W3

If W takes a or b B will take c (Obviously W can't take c else B will take d)


Fail 5

[Diagram]

I'll either expand on it later or hopefully somebody else will? ;)


Fail 6

[Diagram]

That ko again

[Diagram]

W3 mistake


Fail 7

[Diagram]

A good (direct) ko for B

[Diagram]

B2 mistake
