[Bug-gnubg] race net: 0ply and 1ply

[Joseph Heled]

I now have a race net whose 0ply move error (as given by the race benchmark 
which you kindly helped to roll) is 62% of the current net. The 2ply error is 
90% (i.e. 10% better). Alas, 1ply error is twice as large!

This is a somewhat bizarre result. I think I know in part why and will try to 
solve this, but it seems that improving the 1ply will degrade the 0ply.

This raises a theoretical question. would YOU rather use a net with better 0ply 
and 2ply, or a lesser one with a better 1ply?

Personally, I never use 1ply anymore. I use 0ply for quick, 2ply for more 
quality, but I would like your opinion.
