A nice feature to have in a chess program is the ability to resign.
Based on my experience on the ICS, it would seem that gnuchess doesn't
have this. Any thoughts on adding it?

I guess you do it by having the program resign if the evaluation
has been below a certain score (resignScore) for a certain number
of ply (resignPly).

I'd think that something between 7 and 10 pawns would be good
for resignScore. Maybe 6 or 8 ply for resignPly.

If you have it equal to 1, the program will probably resign positions
where the opponent doesn' t see the win. Having the resignPly > 1 also
helps to guard against miscalculations by the program causing resignation.
