Joseki error.

Black still has an escape for height-3 ladders, White does not, and it is White who spent a net move here (2-vs-1).

C3 is the usual move for White.]

I think D11 instead.

This is what I tried, since k8 instead would've failed to i9.

I feel there was probably a way for you to still connect through this corner, although I didn't have any specific idea in mind for you.]
;W[k8]C[Eric\: maybe I11?]

L3 is a better try, since it captures M3.

However, I now see that black K4 would almost-certainly still work.]
;B[k4]C[Eric\:

Since white K3 will leave a ladder escape fork at L2, I was able to prove I was winning here.]
