Six Good And Six Bad Shapes/ Discussion

(sIG): Just one thing... in Pushing from behind is mentioned the "devastating bend". Why isn't it one of the "good shapes" since it is so grreat?

They seem at least as good as the good shapes mentioned on the parent page. Maybe they were considered too elementary.

eggsyntax? Could someone explain how counter-hane and double hane could both be good shapes, when counter-hane sets the opponent up to do double hane? I'm very confused by that. Thanks!
