Otherwise, Black will connect there, enhancing the final scores in his favour.

Black plays 3/5 reductions.

Please assume the rejection of Dany's Sacrifice (, ) played before.

With 5/5 reductions, the final scores would be Jigo / White + 4.

In the left centre - after has been played - White will enforce the sequence to .
Later, White will play her kikashi , , so that Black will have to capture at before the end of the game in the Capture Variation.

White on her side will suffer from the final ko in the upper right centre - found by Joachim ( 648ag) - that depends on the existence of two White cutting points in the centre (), and Black's ko threat at in the left centre.
Black's large group in the upper right will not survive the semeai, but Black will capture White's two wC-stones.
