If I read your post correctly, you mean something like this
In general, ---etc is not a good idea, because black is pushing from behind. If you keep it up like that, white is constantly ahead of you, and may chose to bend around (hane) on the front of your stones (eg: at a instead).
Usually, something like is better, jumping ahead. Now and are pushing from behind, and maybe black will hane in front.
The risk of , however, is that white will cut like this. Whether this is possible depends on the surroundings (eg: is the edge of the board nearby?)
If you think that the cut is too dangerous, instead of the first jump, you can play this knight's move jump of . Now - might follow. This is better than pushing from behind.

It is useful to know how much pushing from behind you need to do.
Now black's connection is locally secure, because can be captured in a net, starting with a and then b. In general, this is overkill, and black will have given up too much to the line of white stones underneath. By adding a 4th stone to , all these black stones become heavy and start to restrict black's options.
More fundamentally, if black doesn't want to get into this kind of mess, he shouldn't attach to the white stone like this.
The shoulder hit of is very often better for black. Now if white continues locally at either a or b, it is white that is pushing from behind, rather than black.

This is a fantastic discussion. It seems to me it should be incorporated into PushingFromBehind, which at the moment is much less comprehensive.
