(;B[qq]C[An active approach, the corner is big. But this was not optimal.]

Descending at A was also sente for white against the corner, making it even more difficult for black to live on the right side.])

The exchange of white A for black B is very good for black. On top of that, white's shape on the outside is not great.]
