Obviously one would expect the openings advisor feature to add some advantage. It was a matter of determining how much.

Cheers,

Ok, and if it is part of the engine the question is: Why switch it off? what is the intention of testing it on or off and why is there a possibility to switch it off at all?

Nevertheless, the best Shredder has the function ON - I am fine with that!

Maybe it's intended for some analysis situations, if the user thinks a particular position shouldn't be treated like an opening position, e.g. even if the developement isn't finished yet?

(I did look in the Shredder 12 manual which can be read online at Shredderchess.com, but didn't find that feature.)

Still no more than 10-30 elo difference depending on which list you look at.
