If Ruffian doesnt have booklearning as an UCI engine that's a missing feature, nothing more, nothing less. It might be difficult to implement but it's not impossible, as others have it. That's similar to the time usage discussed somewhere else. Ruffian (only as an UCI engine?) doesn't use its time in an optimal way (an understatement) in 40/120. So is usage of this timecontrol unfair? Btw, I expect this problem to be more severe than the book issue because Ruffian's book is quite wide. I am convinced a future version of Ruffian will take revenge anyway :). Peter
