Against the marked approach Black's diagonal response at is simple, and good for territory. Now White at can be considered still to be the standard answer, but extending as far as a is increasingly seen in pro play, for a lighter position. This result is locally considered good for Black, but
White normally plays this approach when a black pincer on the top side would profit black even more.
DaveSigaty: I would like to interject two points about this. See 34 point distant low approach statistical analysis.

Dieter: I'd like to learn more about this fuseki pattern because it often occurs in pro games and it happens to be played against me as well. I assume this is a Kobayashi fuseki variant. The kosumi that this page is about is .

... this is what Dinerchtein in his commentaries on go4go.net very often describes as "the usual pattern". I'd like to understand more about the peep at . I can see it coming that thousands of amateur games will contain this "joseki move" without anyone understanding its purpose.
My ideas: if at a instead, Black doesn't need to defend at because a white approach there can be cut off thanks to the gap at . In this case, both defend. Question: what happens if is left out ?
Charles Well, first, I guess at the circled point is more the normal idea. If we are talking about the variation with , that's less common than one to the right, of course. And I know more about the peep when is at the square-marked point.
That all being said, Sasha is talking about things 'well-known' in Korea, amongst the young pros. His commentaries assume this kind of background.
There is nothing especially mysterious here, I think. If is forced, and there is no way to resist, then becomes an inducing move for . There are other examples on SL that I'll reference when I find them.[1]
Just one point, mentioned by Guo Juan when she was in London a few year ago:

It seems that is the tactical chance to avoid being forced.[2]

Charles I don't see any pro examples exactly like that. I do see what's in this diagram: after an earlier exchange / / , White uses the kikashi to strengthen. This controls the stone to some extent.
