Volume 1, Problem 64, p. 131

The answer given is B1, but a and b also work.

[Diagram]

Volume 2, Problem 62, p. 127, W4 at B1

The book solution is just B1, W2, B3. But after this, if W4 at B1, then B5 may not be easy for beginners to find, so it should be mentioned in the solution.

[Diagram]

Volume 2, Problem 105, p. 214

B1 is given as answer, but W2 defeats this. After B3-W6, black can't play a. If B3 at W4, then W4 at B3.
The correct answer is B1 at W2: see the next diagram.

Volume 2, Problem 105, solution

[Diagram]

Volume 3, Part 1, Problem 26, p. 53

In the first solution diagram, B1 and B3 should be played in the opposite order, B3 first. (The next two diagrams show why B1 first fails.)

[Diagram]

Volume 3, Part 1, Problem 28, p. 57: failure

In the book's solution diagram, W2 is a mistake, and should be at a instead. White sacrifices white+circle to prevent black+circle from connecting out. (According to KataGo, this may actually be the best play for both sides in some full-board positions, but it doesn't achieve the problem's goal of connecting.)

[Diagram]

Volume 3, Part 1, Problem 28, p. 57: solution

If black does need to connect out, B1 is the way to do it. After W2 and B3, if W4 at a then B5 at b catches white in a shortage of liberties.

Volume 3, Part 2, Problem 5, p. 69

The circled white stone should be a black stone. (The diagram is upside-down in some editions.)

[Diagram]

Volume 3, Part 2, Problem 7, p. 73

There is no clear-cut right move here. KataGo thinks that any of black a, b or c next could be best: it gives different answers depending on what the rest of the board looks like. Note that black b captures the two white stones on the left due to a shortage of liberties. (Just for interest, this position does come up in a pro game: Takagawa-Fujisawa, 3rd Honinbo preliminary round, GoGoD 1944-09-06b, at move 53. Takagawa chose b.)

[Diagram]

Volume 5, Problem 11 Connecting Error diagram

The circled black stone should be a white stone.

[Diagram]

Volume 5 part 3.2 problem 4 (page 237)

The book gives black a as the solution, and black b as a mistake. In fact, black a fails: white can escape by playing either b or c.

[Diagram]

Volume 5 part 3.2 problem 4 (page 237)

The book gives this as a failure diagram. In fact, B1 and W2 in this diagram, followed by B3 at a, is the correct solution.

[Diagram]

Volume 6, Problem 21 Attacking Error diagram

The circled white stone should be a black stone
