In 2014, we finished our theoretical analysis, whether Black could successfully use the three kikashi in the top left corner ( An exemplary application case can also be found earlier in this book ( |

If White wanted to pre-empt Black from forcing her to start the forthcoming ko-semeai on the right side "early", she would have to insert the kikashi in the top left corner first, starting with the atari of |

In the middle of 2013, when analysing the consequences of Michael Redmond's kikashi in the bamboo joint ( |

White could successfully start the ko on the right side "early", with a move at White could also do without these kikashi in the top left corner, which we had thought of as a kind of precautionary measure in the very beginning of our investigation of Joachim's Ko-Semeai. As we ultimately understood in 2014 (late, but not too late), there is really no need for White to play preparatory moves in the top left corner, in order to create potential for own ko-threats in this area. |

As a matter of course, Black is unable to eliminate his weaknesses in the upper left corner with a move at |

Again, White should not occupy an outside liberty, forcing Black to connect the hanezeki's tail. |

As already mentioned above, it will not prove advantageous for White to occupy another direct liberty, for example at |

Here, Black connects the hanezeki's tail, and so captures White's three stones, because his top right group has only seven liberties left. Otherwise, White would capture Black's centre group with a move at Alternatively, Black could use his local ko-threat in the hanezeki, at |

White's group has five liberties, three shared liberties ( Black's group in the lower right has five liberties, too, four direct liberties ( Black's group in the upper right has seven liberties, three shared liberties ( |
