Hi Sedat,

I am still surprised that with Ponder ON, you are able to finish matches with Strelka.
(I think you use Fritz GUI and Shredder GUI)
How often do you get crashes or loss by "Time exceeded"?

Hello Ernest,

There were several time crashes....i can't remember exactly the number

Those Strelka error bugs are appeared under Fritz/Shredder and even under Arena too

But anyway Strelka 5.1 had less crashes under Arena GUI

Note that mostly of the Strelka games are played under Arena GUI with disabled option:
'Restart engines after each game'

Best,

Hello Sedat,

thanks for your new book version. Most interesting available opening book I think. Perhaps for testing engines a lot of more variants should be open in your book.
But all other is perfect, good name for this work

Best
Frank

Hello Dear Frank !

First of all i'd like to say: BIG Thanks to you (for your kind words about my work since many years)

You are not only one of the biggest Experts in Computerchess,but also you are one of the good positive people,who have BIG heart too !!

And now about the openings...
Actually i like to see more various openings,e.g ,Benko/Volga Gambit,Alekhine,Scandinavian,Dutch...have been disabled in Perfect 2012 book

But in case of allowing the above openings, unfortunately mostly of the top engines are falling in a big disadvantage
I mean the chess engine's winning percentage are falling down,mostly of the top engines performs bellow 40% and that hurts the elo performance

And from my experience i can say that if the above openings are enabled,then (for reliable rating) it is needed at least 1000/2000 games per each participant
For example,in case of using Perfect 2012 book:the engines elo performance stay almost same...i mean 400-500 games are enough for reliable rating

BTW,here are available some notes about why those disadvantage openings are disabled in Perfect books:
