Capture Variation:

Compared to the superordinate variation ...

• Black got one point of territory in the left centre, but did not capture a White stone there, so the net effect is zero.
• Black's cumulated gain in the lower left corner is one point.
• Black did not destroy one point of White's territory at the top.

In total, gains and losses compensate for each other.

White + 1 => White + 1

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.
