perhaps black hoped for this variation (black can continue with a or b):

Playing around with katago (40-block), I think that just before this is also interesting. Katago calculates that the shoulder hit at "a" played in the game is not bad, but not the best. At 100K blue is the other shoulder hit at "b". However, the pincer at 1 is right in there, slightly better than "a" and slightly worse than "b". Katago calculates that Black peeps at 2. The interesting point is how to answer

and what to expect?

At around 200K, katago prefers attaching at

below and letting White cut through the knight's move (!) while capturing the pincer stone. This gives White sente to turn away to the top.

Almost as good, however, is pushing up at

below. Rather than continuing on the bottom, Black answers the cut with

in order to play against the White stones on the right with

. This idea is not on my radar screen at all.

The only idea I would have for playing this

would be to build strength to play on the bottom.

EDIT: As is not too uncommon in my case, I forgot to close katago when I wrote and posted all this. When I noticed later, katago shifted

below to "a" somewhere on the way to 1 million PO's. Black may or may not get back the right side later.
