Wedge - when the approach to 3-5 is possible
There are good reasons for not counting
here as an approach play, in relation with Black's 3-5 point stone.
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]
Clearly the positioning of
indicates that White would be happy in the overall position to settle a group with
here.
An example where this is known in pro play is in a Kobayashi variant:
This is from Hong Min-p'yo-Ch'oe Ch'eol-han (B) 2003-03-07. White uses caution in playing into the formation of the
stones.
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.

The end position here would differ by one line from the Kitani wedge idea in the enclosure opening.
