Beginner Exercise 255 / Solution

Solution.

The solution is B1, making miai of a and b.

[Diagram]

Main line.

Specifically, if W2 descends , then B3 and B5 lives.

Be careful, if B5 is greedy and plays at a, then White b removes the second eye.

[Diagram]

Variation.

If W2 makes a placement, then B3 and B5 captures the W2 stone and lives.

[Diagram]

Failure 1.

B1 here is greedy. The placement at W2 makes a and b miai for White.

[Diagram]

Failure 2.

The descend of B1 is also a mistake. After the hane-connect of W2 and W4, Black does not have enough space to form a second eye at the bottom.
