Go up one level in this thread
For fun I picked one of the positions from your list at random and
analysed it overnight on a 450Mhz machine using Crafty 17.5
The nps count seems a bit low, it may have been slowing down at the
larger depths. Anyway, it shows that in this position crafty does eventually
get to a more equal score. Is anyone willing to try this or others
with crafty or other progs such as rebel?
