Variations of Our Solution (IIIa)

No Early Kikashi

VAR (.4)

: ( 648hm)
Black's "early" connection in the left centre is a mistake.

:
White secures two points of territory in return.

:
The Main Semeai continues.

Black plays 3/5 reductions.

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

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

Capture Variation:

Compared to the superordinate variation ...

  • White got two points of additional territory in the left centre.
  • Black does not need to capture White's two stones in the lower left corner, so gaining one point.

In total, Black lost one point.

White + 2 => White + 3

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.
