Beginner Exercise 132 / Solution

Solution: Seki

B1 maximizes the eyespace and threatens to make a separate eye at a, requiring W2. Then B3 makes a seki life.

Neither player wants to play at a or b. If Black plays one of them, White makes a bulky five by connecting at c. White plays at a or b can be captured later. So both groups are alive in seki.

Variation 1: Life with points

If White doesn't play W2 as in the diagram above, Black can live without seki.

Failure

The other descend B1 is a decisive mistake. White reduces the eyespace with W2 and kills by making the bulky five. Defend the longer side where you can make a separate eye.
