feobos-v20.1-contempt_3-5_tuned-v2.bkt

An order to create a stronger opening book, based on FEOBOS project databases!
https://www.amateurschach.de/download/_feobos-v20.1.zip


based on:
FEOBOS 20.1 Contempt 5 database (Elo 3.000 in database)
FEOBOS 20.1 Contempt 3 database (Elo 3.000 in database)



Step 1:
1. FEOBOS 20.1 Contempt 5 database   =  22.187
2. FEOBOS 20.1 Contempt 3 database   +   2.060  (C00-C99 games, from FEOBOS 20.1 Contempt 3)
3. Positions deleted                 -     194  (collected positions, forced quick draws below
                                                 20 moves, from own produced eng-eng games)
   = used positions                  =  24.053
   
ECO codes added with ChessPad 2.09: http://www.wmlsoftware.com/index.html

With the results:
- lesser quick draws below 20 moves = lesser games to replay.
- Contempt 5 database contains proportionally fewer C00-C99 games.
- C00-C99 codes generally produced less quick draw games.

Step 2:
feobos-20.1-contempt_3-5_tuned-v2.bkt created with 24.053 positions!

Step 3:
Added graphics for Shredder GUI settings in *.zip file (directory: shredder-gui__main-settings).


Notes:
- the opening book should play all 500 ECO codes.
- maximal possible and hand tuned FEOBOS contempt factor, for all balanced opening positions
  inside.


Positions = 24.053
ECO A =   5136 Games (21.4 %) ... mainipulated with priorities!
ECO B =   5531 Games (23.0 %)     "
ECO C =   5510 Games (22.9 %)     "
ECO D =   3691 Games (15.3 %)     "
ECO E =   4185 Games (17.4 %)     "

Move-Range    =  0,5-19,5
Move-Average  =  8,590
Book-Moves    =  119.642
