Variations of Our Solution (IIIa)
No Early Kikashi
VAR (.1) (.1)
: ( 648mk) | |
: ( A 648mt; B 648mx) As we now know, White has to play her kikashi in the lower left corner first. Blocking at at the top, instead, will be also mistaken. | |
: (A 648my) After White's mistake above, simplifying the issue by pushing at at the top, not intending to fight the ko in the centre any longer, will be a succeeding mistake, and one point worse overall. | |
|
: : If White played this move later, as an additional ko threat, Black will ignore it and connect the ko in the centre. White would lose two points overall (compared to the correct line of play above). |

; :
We now know that this atari cannot be counted as an additional ko threat. ; ; ; : Please note that we did not update the board's border colour during this ko sequence. |
: White is comfortably ahead in ko threats (3 x vs. ). : Alternatively, she could continue with the Main Semeai, achieving the same final scores. Black is unable to capture at , and to connect thereafter, because he is too close to the Punishment Semeai Liberty Level. | |
Black plays 0/1 reduction. | |
