Philippe, Many thanks again for being so helpful and quick to respond.
I think there is a bug in your pubEvalVal() function in gnubg-nn/gnubg/eval.c as explained in the attached PDF. If there are men on the bar, these are not subtracted from the number of men off and the total number of checkers is >15.

First: Are the games played to completion? Or are the games terminated at race or bearoff or ... Second: Does the pubeval evaluate all the position classes? I once did the mistake in a similar experiment where the pubeval player actually used a full bearoff look up table. And then: These are cubeless moneygames I assume. These are not one-point matches. (Another potential bug is the opening roll. I guess that it is taken care of.)I didn't use gnubg + some changes, but the gnubg-nn tools from Joseph Heled, so that should be cubeless games without bearoff databases and, at least, directly comparable to gnubg's 2012 numbers.
