Re: Regrading grabs in Aikido...
Most people forget, the aim of an attack need not be to actually hurt someone. What is the easiest way to take a hostage? Grab from the back and eventually put a knife on the throat... There are probably lots of scenarios for attacks from the back, or moving into the back. Just takes a little bit fantasy.
Some people actually don't start from the front, but rather from the side, which is a more natural start for ushiro ryo kata(te) tori.
