The points marked ‘x’ are cutting points      The triangle points are solid connections

The triangle points are hanging connections   White 1 can be captured immediately: no cut

White has a choice of ways to capture the stone, and so connect

White 2 is dangerous...                                ...Black 3 is very good

Again, White 2 is dangerous...                      ...and Black 3 is good

White 2 is correct ...                                ...Black gains some points

Lesson 5 Ko

1

After Black captures, the rule of ko states that White may not recapture at once.

This is an important ko: if White can connect it all the black stones with triangles will die.

   White answers Black’s threat                         White makes threat against Black

Black makes threat against White                  Black answers White’s  threat
