Joachim's Ko-Semeai - Putting the Cart
Before the Horse (2013 - 2015)
12b - White Secures Her Eye to the Right
: However, after , and , ... |

: I am afraid that much more important than the matter of shared liberties will become the problems, which White will encounter by an additional ko-shape that Black will be able to establish on the upper edge - either at , or at . |
|
: We will examine White's hane at , instead, later. |
|
The relationship of liberties has changed in Black's favour now. White's group has five liberties (2 * w, 3 * c), but Black's group has eight liberties (3 * c, 3 * b, 2 * k). Therefore, we can expect that Black will win the ko-fight. |

Despite the changed kind of ko-shape on the upper edge, the relationship of liberties is the same as before. White's group has five liberties (w, 3 * c, m), Black's group has eight liberties (3 * c, 2 * b, 2 * k, m). White will need two atari-ko-threats to win the ko-fight, but which she does not have in the problem. |
