Ko:

:
Black gives atari at the upper string of White's left-hand group.

:
White has to capture the hanezeki's tail now.

Continuing with the ko fight by capturing at , instead, is out of the question here.
White has run out of viable ko threats against Black's right-hand group. Black would turn the upper left corner into a seki, and thereafter still be able to win the Central Semeai on its own.
White would have to capture the hanezeki's tail anyway, but her loss in the upper left would cost her the game.

:
