Beginner Exercise 120 / Solution

Bulky five

The solution of this problem comes when one realizes that the marked spaces actually form a bulky five.

[Diagram]

Black can live

After B1, black has two secure eyes. W2 and B3 are added only to clarify the situation.

[Diagram]

white can kill

After W1, this area is only one eye. The marked space can also never be more than a false eye, so black is dead.

[Diagram]

No ko.

Doesn't black have still a ko if he plays under white 1 ?

unkx80: No. After W3, black dies with a straight three and the marked point is still a false eye.

[Diagram]

ko

White should not capture with W1 here, because she can kill without ko.
