Hello Thorsten, One problem with small books is it will lack variety. Given the same first 5 moves the program will sit there and compute the same answer after 3 minutes. So with this knowledge it's even easier to prepare for it in the same way as if it had a large deep book. There is only one possibility from each position instead of multiple possibilities from a wide book. Of course the only way to keep your small book "unknown" is to make one every time you play a game. Jim Walker
