There are good reasons for not counting here as an approach play, in relation with Black's 3-5 point stone.

The exchange of for is normally reckoned as a loss for White.

In order to appreciate White's play one must look at least at the whole side. Here, clearly enough, functions as a wedge, but and permit Black ryojimari with .[1]

Black rejected the idea of simply taking the corner, instead applying a staircase technique with and . This forced the issue, since White here can hardly allow a big corner. In the end Wc is captured in a ladder, but White next can fight out at a.
