Re: A video guide to playing shutdown defense in Stronghold
 

But pushing them around starts the count, at that point you have a few seconds to push them around. Just trying to figure out what we can and can't do. We got a foul for a defense bot breaking the arm off our bot. (just popped a bolt, was fixed by time the next match started). We'd like to within the rules be able to fight back.

I don't think pushing them around starts the count unless they're up against a wall and cant move or something like that.

Yeah thats how I have always seen it called.
If a robot is completely prevented from moving by another robot (its pushed into a corner its wheels are lifted off the ground, its stuck between two robots) then it is a pin.
If you are spinning out a robot, or just pushing a robot away from its intended direction (without stopping them completely) then I have never seen that called as a pin.
In my head I think of it as "if you are preventing directional inputs on a controller from doing anything then you are pinning if you are not preventing directional inputs from influencing a robot then you are not pinning"
Not that I've ever seen any indication that anyone on the field will be watching controller inputs to robot to robot contact.
