Even with the handicap, I think this is bad, since i3 still has at least a ladder and c4 gives Black a switchback.

I probably would've tried h7, which is a ladder escape, and leaves the option of j2 instead of j3.]

Better C7. This captures D6 and means Black wins even without the K11 corner.

i3 has at least a ladder and c4 gives a switchback for that, so Black should play here.

(The switchback connects to f6.)]
