White blocks at the top.

:
Black pushes for another time, forcing White to connect at .

Alternatively, Black blocks at A14, choosing the Semeai Variation, letting White live in the lower right => about 36 points.

:
Black tries his best to spoil White's eye shape at the top.

:
Creating the ko shape in the upper right, instead, will not benefit Black.

He might even do without, not affecting the consequences of the following moves.

:
Black establishes an eye for his group, but in gote.

If he saved his stones in the upper left by giving atari at , instead, White would connect her single stone in the right centre with . Both groups in the centre would be eyeless, with the better end in the ensuing semeai for White.
Choosing this alternative in the upper left would not prevent the disaster at the right side of the board, but still be about 40 points better for Black.

:
White's centre group is eyeless, and so would lose the semeai with Black's group at the right now. Luckily, she remembers that she can capture Black's stones in the upper left corner at any time she likes.
Here, she takes the maximum profit possible by also capturing Black's large group at the right.

White will win the game by a very large margin.
