Variations of Our Solution (IIIa)

No Early Kikashi

VAR (.4) (.1)

: ( 648ki)
Black pushes once again at the top, also giving atari at White's three stones below.

Please note that we will not update the board's border colour in this subvariation, just because the "usual" Main Semeai will not become effective.

:
White captures the hanezeki's tail.

Connecting at , instead, would be an outright loss without any compensation.

:
Black has to recapture, as usual.


Ko: ;

:
White reduces Black's lower left corner to only one eye.

:
Black is forced to fight, and to win, the ko in the left centre.
However, this ko is a flower-viewing ko for White.

:
This is the first of White's absolute ko threats in the hanezeki.

:
Black has only valid ko threats in the surroundings of his large group at the left side.


Ko:

:
White has too many ko threats in the lower right corner.

:
White captures the ko for the last time.
Black does not have any valid ko threat left that would be large enough to compensate for the loss of his entire group at the left.

White wins the game by a large margin.
