: ( 648aa) | |
: (121 648hn) We also tried the wedge of , instead, but this will end worse for White. : ( 125 648ht; 124 648hx) Taking the large point of at the top right, instead, would be better for her. Black would still win the Semeai Variation, but White could capture his large group at the right, as usual. White might also try Dany's atekomi , but this move is a mistake here, losing one point overall. : In principle, Black loses two Main Semeai Liberties by this move. But becomes an approach-move liberty of his group, so the net effect of this move is a loss of one Main Semeai Liberty. | |
: ( A 648hz; B 648ia) Blocking with at the top, or taking territory in the centre, instead, will not affect the final result of the game (i.e. the score in the Capture Variation), but lessen White's loss in the Semeai Variation. | |
: (136 648ib) It would be too early to prevent White's forthcoming throw-in with a move at , instead. : (138 648ic) Otherwise, Black will connect. Quite contrary to the subvariation above, Black will gain by this "late" connection, after no valuable endgame spot is remaining outside the Main Semeai. | |
Black plays 3/5 reductions. With 5/5 reductions, the final scores would be Jigo / White + 4. Please assume the rejection of Dany's Sacrifice (, ) played before. Before her decision point, White will force Black to capture with , and connect at thereafter. This implies that Black will have to also capture at at the end of the game, due to his lack of an eye above. | |
Capture Variation: Compared to the superordinate variation ...
In total, gains and losses compensate for each other. White + 2 => White + 2 | |
Semeai Variation:
At White's decision point, Black's large group in the upper right will have nine liberties, eight direct ones (), and one approach-move liberty (). Black will win the game by a large margin. | |
