Black does without his kikashi in the hanezeki.

:
White occupies the point that Black just rejected.

Please note that this move is gote in itself, so White should think twice before playing it if there were still valuable spots outside the Main Semeai area on the board.

White connects her two stones in the lower left, refuting Dany's Sacrifice.

White might want to not lose two Main Semeai Liberties by choosing Dany's Sacrifice, instead. Joachim's Final Ko in the Semeai Variation, which is explained in the subvariation below, would not be possible then.
However, her score in the Capture Variation would become even worse.

Black plays 2/5 reductions.

: ( A 648ag)
Black uses only two of five possible reductions here.

Joachim found that reducing White's territory in the upper right by another move would be favourable for Black; he would gain one point overall.

With 5/5 reductions, the final scores would be Black + 1 / White + 6

White will connect at after her decision point.

White will start the Semeai Variation with her forcing sequence , in the hanezeki.

Capture Variation:

Compared to the superordinate variation ...

• White did not lose one point of territory in the top right corner, so gaining one point.

White + 1 => White + 2

Semeai Variation:

At White's decision point, Black will have 10 effective liberties left, e.g. nine direct liberties and one approach-move liberties, as marked here. Therefore, White will be unable to kill his large group in the upper right.

Black will win by a very large margin.
