Solution, step 2

White gets two sente moves in the corner.

Also B10 cannot be at a because then W11 at B10 would create ko for life.

White does not even have to play W11 at once, because Black cannot intrude due to shortage of liberties. That leaves a total of four big ko threats for White.

B10 at B12 would enable White to connect to the marked stone.
