Variations of Our Solution (II)

VAR (L) (A)

: ( 392)
Black continues with the Crosscut Sequence, following the classical line of play. He will win the game even without playing the guzumi.

: (98 399)
Black can do even better, if he plays the hiki at , instead. In principle, this will lead to Joachim's Ko-Semeai that has been explained in great detail earlier ( 225). However, related to these special semeai, Black gained a liberty for this large group in the upper right, due to White's solid connection, and will win the game decisively.


The Hanezeki Exchange ( - ) must be played earlier.

Here, White will gain one point by playing an unbelievable tenuki in the hanezeki in order to attack Black's upper left corner with a hane at .

Please refer to 503 for details why our previous order of moves was mistaken.

:
If Black answered with a move at , which is possible due to the additional liberty for his top right group, he would gain one point in the Capture Variation (Black + 3 then), but loose one point in the Semeai Variation (Black + 2 then).

: (A 404)
White might choose the Semeai Variation, instead, which will end one point worse for her.

Black wins by two points.
