I have downloaded Critter 1.4 for Android and I'm able to play against it, but everytime it starts I get a "book.cbk not found" message. I tried to google about it but found little to no information on what book.cbk might be.
Can anyone point me out how to configure Critter on android to properly use opening books? I'm also interested in understanding how to use Gaviota tables.
Thanks and sorry if I'm asking dumb questions.
