There must be some bug in your implementation. The best neural network that
I have trained for Palamedes (including expert features) reaches 0.603 ppg
against pubeval. I will be very much surprised if I see anything scoring
above 0.75.

I am also curious about the performance of gnubg against pubeval. I would
have done it myself if there was an easy way to get gnubg's cubeless
evaluations from any backgammon position.
