Variations of Our Solution (II)

VAR (C) (B) (C)

: ( 228)
We will look at several variations here. These will be variations that are not simply the same as ones seen earlier, but with the order of moves changed.

: (A 303)
Black plays on the edge here. An alternative would be the cut at .

Playing at , instead, will result in a change in the order of moves. With , , , we get the same situation as with the cut at , shown next.

: (D 305)
It seems best for White to make her eye as large as possible. White's larger eye is also shown in the theory chapter as FLAG 7b ( 1034).
As long as Michael Redmond's kikashi of in the bamboo joint has not been played, White cannot play at , instead, to minimize Black's eye from below.

: (104 307)
Black starts building a larger eye for his group, which results in an unconditional loss only.

Alternatively, he could try to block at , in order to achieve at least a "late" ko.

:
White cannot prevent Black from also getting a three-point-eye, so she plays some kikashi to enlarge the liberty count of her group on the upper edge by one. It will not matter that her group on the left loses a liberty in the process. This effect may become important in other sub-variations as well.

:
Black does not benefit from living on the right side with a move at , instead. White will capture at in sente, thereafter killing parts of Black's top left corner, which is sufficient to get a clear win on territory.

:
Black must connect the hanezeki's tail, because his top right group has only seven liberties left.

:
White wins the semeai with Black's connected group on the bottom unconditionally by one move.
