The formation of White 2 and 3 is known as mukai-komoku (opposing
komoku). Black 5 is not necessarily bad, but White can get the
initiative on the left side. Where should she play ?

Now White can pincer again with 7 (or A), but this time, besides
being a pincer, it is also an extension from her stone at 1.
White is satisfied with this result.
