In igo, when I plan dan-level players, they often make two-space approach moves like the one shown in the figure below:
I have many of the standard books on go and they generally only discuss one space approach moves, so I am not sure how I should regard two-space approach moves from a strategic point of view.
So, here if White had played at C, I would play at B or one space to the right of B, I know that from books. But after the two-space approach, how does that change things? Is it better to pincer now at D or play A maybe?
What is the direction of play when the opponent makes "soft" moves, like two-space approaches?
