Illegal shift/motion or not

[wisref2]

You can argue illegal motion vs. illegal shift all day. In that case, it is both (the motion was illegal because of the shift, and the shift was illegal because of the motion).

Here's how I handle it. The first time the call happens in a game, I pick one or the other. The next time it happens, I pick the other one. I get to use more signals and it makes me look smart.
