:
Black must connect his partial groups in the top right, and he can do so in sente. Thereafter, he must try to reduce White's group on the upper edge to only one eye.
:
Black must set all his hopes on this move, pre-empting the capture of his single stone. If he plays at , instead, White lives with a move at . If Black plays at , instead, White captures Black's single stone with a move at , and has also secured two eyes.
:
However, Black is handicapped by the fact that he is hindered to directly approach White's captured group in the upper left corner from the left side. He needed five moves on the left edge to give atari. So White simply takes a liberty of Black's group, forcing Black to approach her corner group from the right.
:
Black must defend in the one way or the other. If he plays at , instead, White will play oki at , and capture Black's single stone in sente.
:
So, White gets sente to secure her second eye. All of Black's stones on the right half of the board are dead now, so White wins the game with ease.
:
Black might try a semeai between his top right group and White's group on the lower edge, but he will not be successful.
:
We now can see that Black's group has only six liberties left (). So - the forcing moves in the hanezeki are already played - Black would be forced to connect the hanezeki's tail at , to prevent the Punishment Semeai, starting with White's move there. However, White's group on the lower edge has eight liberties (, ) left, against the resulting five liberties of Black's connected group in the lower right corner. White will win the semeai, and so the game.
