: ( 127 222ch) It seems that KataGo likes to insert the kikashi of , in the upper left corner just now. : (125 222co ; B 222cv) Black might want to keep this kikashi in reserve and to give the immediate bump at the top a try. As an alternative option, we also investigate what will happen after Black created an eye in the right centre first, with playing at . : : (128 222cw ; 127 222cx ; C 222cy) Alternatively, she might consider connecting at the left edge with , or extending at the upper edge with . The final scores of these subvariations will be the same as with the correct line of play below. Immediately connecting at the top, however, would be too early here, and so a mistake that loses some points. : There is no need to break through at the top with , instead. : (C 222cz) As two moves earlier, White's immediate connection at will also win the game, but still lose a few points unnecessarily. | |
: (A 222db) He must not cut through at the top, instead. | |
: Please note that White must not occupy Black's liberty at , instead. : ( 132 222dc) However, continuing the ko fight for a few moves will benefit him by one point. I found this improvement when studying one of the subvariations above ( 222cw) that contains a change in the order of moves for reaching this position. : | |

: : Alternatively, he might consider connecting at at the bottom, not affecting the outcome of the game. | |
Black must not play any reduction. White will capture at after her decision point, and connect the ko thereafter. | |
