I took things too easy here with connecting at immediately.
Mistakenly, I thought that this connection would be simply a change in the order of moves, because Black would have to add a protective move in the corner anyway, before approaching White's left-hand group at .

However, I overlooked that the exchange of for is White's sente, reducing Black's corner by one additional point.

Black must block at , instead.

:
White pushes for a second time, in sente, punishing Black for his previous mistake.

:
White got this third push for free.
Compared to the superordinate variation, where White exchanged for before, White's third push at is sente here.

If it were gote, as in the superordinate variation, Black would be able to play an additional territory-destroying move (in the Capture Variation), compensating for his one-point loss in the upper left corner.

:
White must connect her single stone in the right centre.

: ( 146 58av)
Black defends his territory in the left centre.

He would benefit in the Semeai Variation, if he played the descent to at the upper edge, while not affecting the overall result of the game.

: (A 58aw)
Black defends his upper left corner immediately, so taking profit outside the Main Semeai area.

He might continue with the Main Semeai, instead, but will lose two points in the Semeai Variation.

Black plays 3/3 reductions.
