Clearly, the follow-up sequences could become quite complicated, but Black has a better plan, as the next variation shows.]

    C[Because Black already has the marked stone, this joseki makes the result even better for Black.

And although the sequences are non-trivial, White cannot successfully push through with A and cut.]

        C[Black not only enlarges the bottom, but also supports the top left stones.

The game looks very interesting for Black.]
