Gokyo Shumyo, Section 1, Problem 87 / Solution

Main line & variations: unkx80 and Dieter

Solution

[Diagram]

Main line

After 9, White can't play at a because of the snap back.

[Diagram]

Continuation

So Black captures and can connect at 3 if White ataris at 2.

[Diagram]

Variation 1

If White connects at 6, Black 7 and 9 captures the three stones including 8 (White a, Black b and the result is connect and die).

[Diagram]

Variation 2

White can not play this way because the marked black stone makes assures the second eye at the circled point.


Failures

[Diagram]

Failure at 7

The order of play is important here. If Black tries to get a stone at 7 first, then gives atari, White's shortage of liberties has bvanished. She plays 10 to make miai of cutting at a or saving the cutting stones at b.

[Diagram]

Failure at 7 (ii)

Here, White simply connects and has one liberty more than the 4 stones in atari.
