Black fills the ko-shape at the upper edge, so turning the upper left corner into a (temporary) seki.

Please note that this move is played outside the Main Semeai Area (and so does not occupy one of White's liberties), losing one tempo in the Main Semeai.
Black has thus fallen below the Punishment Semeai Liberty level.

:
White can do nothing more but to continue with the Main Semeai.

:
Black takes some tiny profit in-between.

:
This move reduces Black's large group in the upper right to only six liberties (), one liberty too few to survive the Punishment Semeai.

:
Therefore, Black connects the hanezeki's tail, entering the Semeai Variation, which will be better for him than the Capture Variation (where White would choose the Punishment Semeai, to be clear).

:
White's oki is mandatory.

:
White has to occupy Black's internal liberty first.

...

:
Black's oki is mandatory, but comes one move too late.

:
White captures Black's three stones at the lower right edge.

:
Black must give atari at White's left-hand group.

He is unable to play the "usual" oki of , instead, as White would be atari at his connected tail-group.

:
White lives independently in the lower right corner, so killing all of Black's groups at the right side of the board.

:
Black's descent to the lower edge starts a short remaining endgame.

White will win the game by 37 points.
