Dodge question

[Wicked Lurker]

There is a RAW quote that says you can defend against Choke Holds from behind if you are aware you are being attacked.

p. 404 A victim who is aware of you may attempt any legal defense, but suffers the usual penalties for an attack from behind.

Since this is very likely not refering to a runaround attack this again implies you may be allowed to defend if you know you are being attacked from behind.
