Developing the outside  

This way of play, not defending the 4-4 stone but developing the pincer, seems to have been popular mainly in classical Chinese games and is a gate to various Chinese classical joseki.

The fighting old-Chinese way for black is to cut aggressively at a. This position sometimes seems to occur even in modern games (though not early in the fuseki - B1 tends to develop a large moyo), but Kombilo suggests b as the most favoured followup in modern go. (Though the joseki could revert back to Large Opening later.)

There might be more branching that the listed ones, but the popular ones are a - the Large Opening, and b - the Lotus Flower Opening.

The Large Opening

The Large Opening  

Also sometimes referenced to as "Big Corner Pattern", this difficult joseki was apparently quite popular. It has multiple variations (starting by black 1), only one example variation is shown here.

The Large Opening Continued

The Large Opening Continued II; 6 takes ko  

This variation of the Large Opening occurred in a game between Huang Longshi (black) and Zhou Donghou (rotated, colors switched):

W7: tenuki  

The situation is slightly different because of W1. Chen Zude (I think he is the commentator) says that it adds great deal of flexibility to white shape and thus it is wise that black did not follow the usual variation in the end:

Instead of B9, black might push through with a, b, c, but white will set up a squeeze with d and in the end white's top group will have multiple options for escaping while black will be left with troublesome shape in the corner.
