Name for two knights defending eachother


I'm not aware of any specific term for mutually defending Ns, but you could say that they're connected or communicating.

There is no name for it, and that's mostly becuse of the satement of #5, it can be a potential weakness as a knight can be kicked out form defence of the other becuse knights do not move in a straight line.

Hobbled horses, knights protecting each other is a poor strategy , they can get in each others way like stepping on another's shoes
Yeah, but Rosen also calls geese large ducks, so we can't really trust him. At least where ducks, large ducks & geese are concerned.
