iopq: What about here?

erikpan: I'm only mid-level kyu but that seems as if it's too low and has little future. White could for example stretch back into the corner, getting a strong wall going facing to the right while black gains little in terms of territory or influence. Line 2 is played for yose and for saving and killing, traditionally; 2 at 4 would not accord with this quite as well as the above diagram, where 4 is used to save.

Dieter: this move is not the basic technique against the shoulder hit, which is to stretch. As erikpan points out, it gives an inferior result. If we continue with -, Black is indeed kept very low, to the point of even not clearly alive.
