White continues with the ko fight by capturing the nakade.

In this subvariation, we (once) assumed that White does not want to play at in the hanezeki.

White connects, completing the Nakade Sequence.

She will increase her result in the Semeai Variation - despite still losing the ko fight - if she splits the Nakade Sequence, and recaptures the ko in the left centre, instead.

:
White recaptures the ko.

Please note that we will not split the following diagrams for adjusting the board's border colour after a ko threat is played that loses at least one Main Semeai Liberty.

:
Black's utilises his first kikashi in the hanezeki as an additional ko threat that will win him the ko fight.

:
White has to connect.

If she mistakenly played the atari of at the left edge, Black would cut at , killing all White groups in the hanezeki. White would be forced to capture the hanezeki's tail (otherwise Black could safely connect it), losing the game by about 5 points.

Please note that Black's atari at White's two stones in the lower left is explicitly displayed as a ko threat here.

White connects.

If White chose Dany's Sacrifice just now, and connected the ko in the left centre, Black would capture with and White would achieve only a drawn game in the Capture Variation. Black's large group in the upper right would survive the Semeai Variation (due to White's loss of two Main Semeai Liberties by her sacrifice).

Please understand these two moves as replacement for White's kikashi , in the centre, which had been played too early by us.

We now know that this kikashi cannot be counted as an additional ko threat - in the case that we had played Black's atari at before starting Dany's Ko, in order to generate additional Main Semeai Liberties for Black.
Here, in this subvariation, however, both atari compensate for each other in the ko threat count.

Ko:

:
White has another ko threat in the lower left corner.

:

Black's ko threat in the upper right corner - found by Joachim - costs Black one move overall (i.e. an additional prisoner for White) and one tempo in the Main Semeai.

:
White has run out of valid ko threats.

:
Black connects the ko.

Black plays 1/1 reduction.
