Variations of Our Solution (II)

VAR (C) (A)

: ( 219)
Black closes the top left corner.

: (90 224)
Black starts the Nakade Sequence on the left side.

It is much too late now to successfully play the guzumi at 90, instead. The window of opportunity is irreversibly closed.


: (91 222aa)
White gives atari at Black's nakade.

KataGo prefers the atari at , instead, which will benefit White by two points overall.


:
White occupies the guzumi point.


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.

:
Black is unable to connect his single stone in atari, instead. He would lose a decisive liberty, and so the Punishment Semeai.

:
White gained territorially in the upper right corner, so she naturally chooses the Capture Variation.

White wins by two points.

This is the same result as with the classical line of play ( 722), taking into account the two-point effect of Yamada Shinji's tsuke that we used herein.

The Hasami-Tsuke Sequence in the upper right did not affect the outcome of the game.
