I use it in tournament but I think to delay the job of testing it with book when it will not be extremely weak. As far as I see most programmers do not care much about optimizing book(otherwise I could see bigger difference between results in the nunn match of Heinz and results in serious tournaments) The gap between Movei and Shredder8 in nunn match condition is more than 200 elo. I think that closing that gap should be more important than caring about tests with book because the optimal book today may not be the optimal book after I close the gap to shredder8. Uri
