The way I was trained to see this balk: look for the sole of his shoe. If you can see the entire sole, the foot likely went behind the rubber (try it for yourself). Otherwise, legal for a pickoff.

In FED (and NCAA) it's the "entire foot" (or "any part of the stride leg" in NCAA). OBR, it's "any part" of the free foot.

The rest I concur with.

Hadn't heard the "sole of the foot" guideline before. I'll definitely give it a try.
