I think there are notes from Joseph about gnubg training somewhere on the net: anyone has the address ? _______________________________________________ Bug-gnubg mailing list Bug-gnubg@... http://lists.gnu.org/mailman/listinfo/bug-gnubg

I've had a quick look and if the bear-off database isn't used then the 3+4ply results both give double take. This might be entirely coincidental but I'd expect the bear-off values to be more accurate than the race values? Jon New Windows 7: Find the right PC for you.

I did a further test where the code used the logic for race evaluations but actually got the results from the bearoff database (rather than the NN) and this also gave more correct answers (compared to using the actual bearoff logic). Maybe someone can explain the differences in race vs bearoff evaluations? As I would think (on a logical level), that my test above should give the same values as using the bearoff database directly (as all the evaluation are exact).
