Since Black still has a ladder escape in the A1 corner, White needed to push or yield or intrude at D9 or further into the A11 corner.

I would have pushed; see next variation.

Now Black wins. Black keeps this win for the rest of the game.]

Foiling captures the whole corner.

D3 had a connection to the A-edge anyway due to  B6,A7, so D2 is strictly better than C3.

(Also, C2 is equivalent to D2.)

Yes, this is a handicap game and White might not know how to foil, but C2,D2 give Black the ladder escape too.]))

This is strictly better, since it captures A6 and A7,])
