Hi,
As part of my recent research (Elo systems and PR) I generate a number of neural nets, ranging from 500 Elo to about 1800.
I thought it might be a nice feature to have for beginners, to play a weaker, less frustrating, computer opponent. Might also be useful for stronger players - practicing playing against weaker players.
I am willing to adapt the nets to GNUbg. If anyone wants to collaborate with me on the rest, i.e. user interface and glue to the rest of the system, please contact me and we can discuss feasibility.
