I think I will post some analysis from a default >Rebel later tonight. Is the 0.0 score from your program movei? I admit that I did not try movei in the previous post but latest buggy movei show also 0.00 for Rb1 depth=10 +0.00 f1b1 c5b4 b1b3 c6c5 g8e6 a4a2 e6e5 c7d8 e5h8 d8c7 h8e5 Nodes: 8523578 NPS: 167886 Time: 00:00:50.77 I think you are >right about the bookmoves, especially in a correspondence game maybe a program >should have built in an routine to check some bookmoves.

I do not understand the decision of programmer to use the same book for all time controls. I have a very small book so I know that movei cannot find better moves at longer time control but with a big book it is more logical to have moves in the book that are always played and moves that are played only at short time control.
