That could be the reason, but the point is that it won't show a lot because these engines are so strong already that they would have won even with a bad book. It would be far more interesting to give Beowulf a 700 Elo book and then go wipeout Shredder & co in the big tournaments. :) >I also do not beliebe in 700 elo but I certainly believe that they can improve >the performance by 100-200 elo in a tournament when part of the opponents. > >If you have statistics of a lot of games that you get 70% against some program >with line A and 50% against the same program with line B then choosing line A is >important. > >If you have similar statistics for many programs then it may give you >significant increase in performance in tournaments. I tend to think the effect is mostly psychological. I can see how comming out of book with a +0.6 score against an equal opponent must feel like half a victory, and it's not hard for me to imagine that some would call that totally winning :) >Even with no special preperation against specific opponent you may have >statistics that your program score 60% with 1.e4 c6 2.d4 d5 3.f3 and only 50% >against the same opponents with 1.e4 c6 2.d4 d5 3.e5 so of course opening >preperation can help significantly in tournament. I believe such is thing is possible, but increasing your score from 50% to 60% is still not much more than 50-100 Elo. -S.
