3-3 point pincers

It is quite often said that the 3-3 point doesn't support pincer joseki.

That isn't quite true. The 3-3 point does contrast with the 4-4 point: if you play the latter, you can usually answer an approach move on either side, that is, play either with a corner-enclosing play or with a pincer. If you play a 3-3 point, it is much more difficult to play a pincer, and one expects to add to the corner.

Still, there are plenty of examples in pro games of pincers based on the 3-3 point.

A joseki?  

This sequence was current in the early days of komi go.

Relatively recently, the 3-3 point distant low approach, one-space low pincer has been played.
