This is done manually as far as I know. Not much to set. I threw all the hash I
could to it and let it go. After setting the hash verify that the change stayed.
The first time I set mine I had it play a match against Ruffian and Tiger got
killed in a 6 game match. I started another one and watched the game and Tiger
was getting 6-7 ply in  G/10 min. I checked the hash and is was set very very
low. I set it higher again and that was the last match Ruffian has won.

I worried about that myself. You can use Rebel books also. I looked at those and
they were no bigger in Century 1.2  Rebel & Tiger has one of the best book
cookers there is imo. I will let others field the rest.
