When you have this type of situation (6x from the bar and the X or entering number is a four or five and you have a checker on the other point) you always run from the 20pt. This comes up waaaaay often and a lot of the time the difference in plays isnot even that large, .020 give or take. However, the right play is always 20/14. Even I having created this rule, having collected a fair share of positions on it and seeing it tested time and again have no firm understanding of the why behind it. I

Below is a position that just came up today. I "automatically"
played 20/14 and even Stick might call this a whopper. My guess
is that duplication of 3's is a big part of the explanation.

Also it should go without saying that when I put forth a general rule it's meant for normal match scores/money play. Not that it really changes the analysis here but it should be noted.
