The marked white stone is missing in the problem diagram, but present in the solution diagram. In my opinion, it should be present in both, rather than absent in both.

Black to play and live


Here is the book's solution

[Diagram]

Black lives

Black lives by setting up the comb formation. This is possible because Black's move B3 threatens to capture the 4 Black stones on the left.

[Diagram]

Black lives

Black can also start by playing to the left of W4, in order to guarantee two eyes.


It seems to me that White can defend his left 4 stones by playing a typical sacrifice in capturing races, gaining one move

[Diagram]

White gains a move

Now Black can't throw in and atari, due to a shortage of liberties, and has to spend an extra move to capture W3.

[Diagram]

Black gets a ko

I don't see any better result for Black.

Diagram 90: White kills Black

The author writes: if Black B2 at B4, then White W2 - Black a - White W1 kills him. This is not true.

[Diagram]

Variation: White 5 at 1

Black lives with B6.


[Diagram]

Correct variation

White W7 at W1, and this is probably what the author meant.

White can live unconditionally



For this problem the author gives the following solution:

followed by:

[Diagram]

Wrong continuation

Unfortunately W1 is a mistake.


Black may play B2 at W3 here resulting in:

[Diagram]

White is short of liberties



The correct solution is:

[Diagram]

Correct continuation

now black is short of liberties and cannot connect at a.
