Beginner Exercise 70 / Solution

Solution  

Play on the point of symmetry is a good rule in such positions. Since the shape is symmetrical, we show Black replies on one side only - a to c.

a above  

is atari and Black connects easily.

b above  

seems to prevent connection - but Black is caught in a snapback. at is met by at - snapback again.

c above  

White connects again. This is practically the best for Black.

Failure  

only helps Black to prevent the snapback. Keep options open on the second line - in the "a above" diagram, White plays atari on the side with a Black stone on the first line.
