Hey Dieter,
Thanks for running those very interesting stats.
Some info to clear out some confusions:
* Yace is playing as a UCI engine under ChessbaseGUI using it's own book, I
don't know how Yace's learning function works as a UCI engine under CB GUI.
* I don't know if Yace used it's book learning in the first 1000 games, but I do
remember that at some point I added this line: "min_learn_tc 60" in Yace.ini
which you can see here: http://www.pavs.org/yace.ini .
* When I run Yace under Chessbase these are the default value:
http://www.pavs.org/yace.jpg , which I never changed throughout the games.
You will see that Yace has book learning but it's book is set as random.
* Yace played more games as white than as black because this is how my
engine_engine match is setup under Chessbase GUI: http://www.pavs.org/yace2.jpg
So everytime I stopped the games after yace as white, and next game I start
would also play Yace as white. At first I didn't care much, but now everytime I
stop games I make sure that Yace doesn't get more priority as white. However as
you mentioned the games are very few to make any differance and you can always
delete them while making stats.
IMO Yace learning is clearly helping here. If you just consider the last 2-3-4
thousands games you will probably see that Yace performance was superior.
The question is does this learning actually help yace when playing longer time
control? ie, 15min/side?
