Volume 1 Problem 74 (transposed)

The marked Black stone is mistakenly shown as White stone in the problem section of the book.

Volume 1 Problem 74 (transposed) Solution

B7 at B3.

unkx80: This diagram looks ridiculous - B3 captures five White stones, and hence B7 cannot be played on top of B3.

[Diagram]

Volume 1 Problem 74 (transposed) Failure

unkx80: Then B5 captures at a. How is this a failure diagram?



unkx80: Why is this an errata? May I assume that it is Black to play?

[Diagram]

Volume 1 Problem 74 (transposed)

unkx80: If WC is indeed a White stone, then this is the solution, which results in a ko.



Volume 3, problem 193

[Diagram]

Problem 193

The theme of the problem is: Black will get an eye at the marked point, she must find a method of creating a second eye.

[Diagram]

Book solution 193

[Diagram]

Refutation of book solution

The marked point is not an eye. White will squeeze at 'a'. Black has only one eye.

[Diagram]

Refutation

If B1, W2 - W4 kill. After W4 Black is damezumari. (Found by Jantje).

Suggestion

ferdi suggested this correction to the problem.
