FLAG 8a: ( 1036) Compared to main line (with a larger eye for Black, after White's move at , and Black's moves at , and ), there will be no effect. Black will still need one external ko-threat. Compared to the smaller eye for Black alone, Black needs one external ko-threat less. FLAG 8a1: ( 1040) |

FLAG 8a2: ( 1043) FLAG 8a3: ( 1045) |

FLAG 8b: ( 1047) But Black must not do so, because White will win by double-ko. Please note that there is a precondition that Black needs to play a protective move in the upper left corner, to enable wholly approaching White's centre group. |

FLAG 11: ( 1068) White's solid move at , in an attempt to simplify the matter, is not possible with Michael Redmond's kikashi in the bamboo joint ( / ) being not played already. This means that White's options in the centre are limited then. |
