I'm interested in hearing/seeing other examples of how this problem might be solved in an 'internal' way.
Forrest's sink the chi Stupid Jin Trick is a representation of peng jin.
You can use what I was referring to in the other thread.
Structural alignment will eventually fail given enough force. When you are using jin, it doesn't quite work that way as the other person never can exert their full potential on you because they're always off balance.
