Capture Variation:

Compared to the superordinate variation ...

• Black's cumulated loss in the lower left corner is two points.
• Black captured two White stones less in the lower left, so losing four points.
• White did not capture Black's stone in the lower left, so losing two points.
• Black destroyed one point of White's territory in the upper right corner.

In total, White gained three points.

Jigo => White + 3

White lost one point overall.

Semeai Variation:

At White's decision point, Black's large group in the upper right will have nine liberties, eight direct ones (), and one approach-move liberty ().
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 large ko threat at at the top.
Black's large group in the upper right will not survive the semeai, but Black will capture White's wC-stones in the upper left, and win by about 15 points.

Black will win the game by a large margin.
