1001kyu: Unless I'm missing something, it is possible to imagine breaking through with something like C11B13E12D11E14F13D14.
I don't see a reliable way for the opponent to kill in this case, so maybe an additional stone on the outside would be useful. Or you could add the variation C11D11A11B10D14E14B14, which would require a bunch of other variations depending on move order...
