Black plays Joachim's tenuki, and captures White's single stone in the upper right.

:
White plays her first kikashi in the lower left corner.

: ( 130 649ap ; A 649ar ; B 649as)
KataGo favours to continue with White's second kikashi there immediately.

However, preparing the path to Dany's Ko with the wedge at in the left centre would be better for White in the Semeai Variation. KataGo simply does not care about the final result of that alternative Main Variation, and therefore does not favour this move.

Playing the central attachment at in the left centre, instead, is a mistake here, losing one point overall.

The same is true for the connection at at the upper edge, which would be too early now.

: ( C 649at)
KataGo (2021i) favours Black's connection at the lower edge here, providing us with evidence that it does not care about the result of the alternative Main Variation (i.e. the Semeai Variation here).

Quite surprisingly, KataGo's solid connection in the centre - that is "usually" played in other subvariations - is not favoured by KataGo (2021i) here. Choosing this subvariation would not affect the outcome of the game, but benefit Black in the Semeai Variation by four points.

:
We continue with White's wedge in the left centre.

KataGo captures at before. We think that this does not make a difference, as Black has already played the push at the top that hurts his upper left corner decisively.

: ( 136 649au)
KataGo likes to play this atari immediately, but which loses a ko threat for the case of Dany's Ko.

Dany's atekomi at is favoured neither now, nor after Black's connection at . We can assume for sure that KataGo does not care about the result of the alternative Main Variation.

:
KataGo favours the central attachment in the left centre.

White would benefit by one point in the Semeai Variation, if she played Dany's atekomi at - followed by Dany's Ko - instead.

:
White secures two points of territory in the left centre.

:
Black pushes at the upper edge in return.

:
Black is able to connect.

Black plays 2/2 reductions.

Before the end of the game, Black will have to capture at .

Capture Variation:

Compared to the super²ordinate variation ...

• Black destroyed two points of White's territory at the upper edge.
• White's cumulated gain in the left centre is three points.
• White's cumulated gain in the lower left corner is two points.
• Black captured White's single stone in the upper right, so gaining two points.
• White did not capture Black's stone in the lower right, so losing two points.

In total, gains and losses compensate for each other.

White + 2 => White + 2

Semeai Variation:

Compared to the super²ordinate variation ...

• Black destroyed two points of White's territory at the upper edge.
• White's cumulated gain in the left centre is three points.
• In the lower left corner, Black lost three points of territory, but captured an additional two White stones, so the net effect is zero.
• White captured an additional two Black stones at the right, so gaining four points.
• White lost one point of territory in the upper right corner.

In total, Black lost four points.

Black + 4 => Jigo
