EPC Question

In Response To: EPC Question (Klaus Evers)

I'll give away all my secrets, maybe someone can add to them.

"Rolls" position: EPC = 7N + 1, where N is the number of rolls left.

Closed board wastes 10 pips, 7-5-3 wastes 7 pips. Six checkers spread from 6 to ace point waste 7 pips, three checkers spread on 6-5-4 waste 5 pips. (EPC = pip count + wastage)

Outside checkers: EPC = 3.5N + P, where N is the number of total checkers left and P is the pip count of the outside checker(s).

Anything in between: eyeball or use Keith/Ward adjustments.

Very good articles on EPC at http://www.bkgm.com/articles/EffectivePipCount and http://www.bkgm.com/rgb/rgb.cgi?view+1076.
