If you're ahead or equal in the pip count, and your opponent has one[...]
or more checkers back, then you typically gain a lot by converting to
a position in which you have no checkers back. This potential gain is usually worth exposing your last checker to a double shot, or
sometimes even a triple shot.
What I often see are players who are afraid to run the last checker
into a double shot, because they underestimate how much they gain if
they are missed and they also underestimate the danger of having their
last checker trapped and/or attacked.

This would seem to be an exception to Pottle's law, at least Stick's
version of it. Few things are more constructive than making the four point.
