Kyu Exercise 23 / Solution

Solution

[Diagram]

Solution

White wins the capturing race on the right with two liberties. Note that black can't play on any three of white's middle-group liberties, as they're all self-atari.



Failure

[Diagram]

Pyrrhic victory

W1 looks like a solution, but it fails on the right: White needs 4 moves more to kill Black's right group, while Black needs 4 moves to kill White's right group, and next play is Black's.

[Diagram]

Complete Failure

Any of W1 fails, as it allows one of the B2. Then White cannot approach further in the center because of self-atari and Black is faster in killing the center White group than Black can approach from the left (a, b, c).

[Diagram]

Not fast enough

White playing from the left gains nothing relevant, not even the left Black group, even when using the ko-play W5.
