Variations of Our Solution (III)
VAR
: ( 503) Please refer to "KataGo's Unbelievable White Atari on the Left Side" ( 1093a) to see why this atari does not work when played earlier or later. Please note that we inserted the Hanezeki Exchange - (played before the Crosscut Sequence), as found in 2017 to be the correct timing for these moves. | |
: (A 548ka; 97 548kb) Black must not answer White's atari by capturing at . Black might want to immediately complete the nakade by playing at , in order to keep his nakade stones at two liberties, but this move will result in a change in the order of moves only. : | |
: (A 548kc; B 548kd) Preceding the move at by the atari of will not help either, as White has a surprising local response at her disposal. | |
: | |
: (106 548ke) Black might want to resist more forcefully, by giving atari with instead, but will suffer by one point in the final score. Please note that Black might not be able to act as forcefully as he wants to do in the top left corner. He has to play attention to keep his ability of occupying White's marked liberties without any delay; otherwise White will choose, and win, the Punishment Semeai. : (A 548kf) : (B 548kg) | |

: (123 548kh) White might choose the "usual" continuation at to reach the same final result of the game – in the Capture Variation – but she will suffer by one point in the Semeai Variation. : : (A 548kj; B 548kk) Black can also immediately block with to reach the same final scores in both Main Variations. KataGo preferred the solid connection at , but which is one point worse (in the Capture Variation), according to our estimations. | |
: (A 548kl) White might also push at to reach the same result of the game (in the Capture Variation), but she will suffer by one point in the Semeai Variation. | |
( 132 548klk; A 548klp)
Dany found that playing the atekomi of , instead, will benefit White by one point in both Main Variations. If White ever wanted to play the central attachment, she would have to precede it with her kikashi of , , in the lower left corner. However, Black would be able to win the Semeai Variation in this case. : (134 548km) Black can also capture at , instead, to reach the same final scores in both Main Variations. These two moves are miai. : (137 548kn) She can also play at in the centre, instead, to the same effect. | |
: (A 548ko) KataGo's preferred line of play uses the move at from below, favouring White by one point in the Semeai Variation (under territory scoring). (B 548kp) Connecting at , instead, forcing Black to capture with , will not affect the final score of the game, but worsen the Semeai Variation for White. | |

: (A 548kq) Despite the fact that White – compared to Our Solution (2017) – added four stones to her large group at the left side (), but Black only two to his large group at the right (), what seemed to confine White to the Capture Variation, she might also choose the Semeai Variation to get the same final result as here with the Capture Variation. | |
