Beginner Exercise 27 Solution

[Diagram]
Diag.: Black saves the groups

Any 'a' is answered by either 'b' and vice versa. Thus black secures eyes on the left group. So white attacks on the right. It looks like black won't have enough EyeSpace. But the cutting point (circled) proves fatal to white's plans.

Diag.: Black saves the groups

Black 3 threatens to capture and thus connect the groups, so white must fill. Black 5 makes the necessary eyes.

Diag.: Black saves the groups

Any other inside play, or a play at the squared point, is met by black 3, which gives atari and also settles the EyeSpace into a BentFour. The circled points are miai to DivideTheSpace.

If white fills, black can still claim enough EyeSpace this way. In this variation white can't play 6 at 7 because of damezumari, and black captures to make two eyes.
