Kyu Exercise 23 / Solution

Sub-page of KyuExercise23



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.


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.

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).

Not fast enough  

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