TOP-Engines whisper us the balanced moves of opening theorie. They will have and we ... the slaves ... try to understand it. That's called: FEOBOS

That's strong TOP engines, made something others in openings and in most of cases very interesting.
I hope I can test this group of engines for FEOBOS, unclear at the moment!

Time of project: ~ 1 year

You can find here a collection of selected "FCP Rating List" games (~ 80%), newer missed
grandmasters theory games from 2014-2016 (~ 5%) and additional game material on rare
opening lines which I haven't at first (~ 15%).

Games are from selected "FCP Rating List" material based on my own "FCP Live Book", that
were under many years of development. With my own "FCP Live Book" engines try to find often
new lines on its own after the end of ECO code lines.

Summarized, my basics comes from:

- high quality TOP-50 computer chess games on Intel® Core™ i7-4770K hardware with 4Ghz and
  40 moves in 10 minutes with an Elo average from around ~ 2950-2975.
  Please have a look under: http://www.amateurschach.de/main/_conditions.htm
  80% of these material aren't susceptible for fast 3-fold-repetition.

- high quality correspondence games
- high quality grandmaster games
  I am working most of times with Chessbase & TWIC databases.

Before I start the project, "beta-v01.pgn" was cleaned and where analyzed with:

1. "beta-v02.pgn" = Stockfish January 16th, 2017 BMI2 x64
   Setting: > 0.50 / -0.30
2. "beta-v03.pgn" = Komodo 10.3 BMI2 x64
   Setting: > 0.50 / -0.30

- Intel® Core™ i7-4770K, 4.3 GHz
- 4 Cores / 8 Threads (Hyperthreading)
- Windows 7 Professional x64
- 2Gb for hashtables
- 30 seconds per end position
- eval = 0.50 / -0.30

Main interest:

- a strong PGN database for engine-engine matches / tourneys / rating list systems.
- a strong PGN database for openings book developers.
- a strong PGN database for Arena Chess GUI "PGN-Random" feature.
- a strong PGN database for building of strong test-sets for engine research.

- opening book in Shredder Classic GUI *.bkt format
  current versions will be available during the project-time, called FEOBOS v1.0 / v2.0 ...

Additional information:

- move transpositions are included (important for opening book developers).
- length of lines = 3 moves after the ECO code was formed, minimal 4-6 moves.
  Please have a look in the file: "beta-v01_eco-codes-length.txt"
- nevertheless, enough _balanced_ lines to all 500 ECO codes are inside in "beta-v03.pgn"

Current status:

10 engines will be analysed the same and important: "beta-v03_endpos-n.epd"
03 "experimental engines" will be analysed the same and important: "beta-v03_endpos-n.epd"

"beta-v03_endpos-n.epd" = without dublicates (move-transpositions, end position)
"beta-v03_without-dublicates.pgn" = without dublicates (move-transpositions, end positions)
"beta-v03.pgn" = with move-transpositions (important for building opening books)

- Intel® Core™ i7-5930K, 4.3 GHz
- 6 Cores / 10 Threads (Hyperthreading)
- Windows 10 Professional x64
- 4Gb for hash tables
- 60 seconds per end position

v01: Setting: > 0.65 / -0.40, Houdini 5.01 Pro x64
     Result: 838 found = 3.20%

Initial situation after beta-v03 ("mt" = move transpositions)
26.146 lines without "mt" = 81.963 lines with "mt"

--- comming soon ---

v07: Andscacs X x64
v08: Booot X x64
v09: Stockfish X x64
v10: Komodo X x64
v11: Fizbo 1.9 BMI2 x64 (experimental for this project)
v12: iCE X x64 (experimental for this project)
v13: SmarThink X x64 (experimental for this project)

= 26.146 positions x 1 minute x 10 engines = 261.460 minutes
= 261.460 minutes : 60 (in hours) : 24 (in days) = 181,56 days analyze time
= 18,15 days for a final engine result!

FEOBOS v5.0 (June 12, 2017)
rank's Encyclopaedia Of Balanced Opening Systems

Note: Please be informed that FEOBOS v5.0 based on work files after engine analysis v05 and isn't ready yet!
Sure we can speak from a ultra strong "prototyp".

125.047 moves based on
77.606 lines with move transpositions!
3 moves after A00-E99 ECO codes formed!

Opening Book 1 for Shredder Classic GUI

115.595 moves based on
24.218 lines without move transpositions!
3 moves after A00-E99 ECO codes formed!

Opening Book 2 for Shredder Classic GUI
*** An opening book with a perfect calculation of probabillities (Prob) ***

You have to set the "IMPORTANT Book Options" under Shredder Classic GUI!
Priority's & 1-0, 0:1 stats no longer necessary with a clean database!

feobos by Frank Quisinsky

And the same for Chessbase Fritz GUI


Highest length in one of the 500 ECO codes is 17 moves!
Variety of play is optimal with 222, it is required or ECO codes A02, A03 never played!
Shredder Classic GUI made it better with 0.1% steps as Chessbase Fritz GUI with 0.4% steps!

Furthermore, 7.0% for 1.c4 and 6.2% for 1.Sf3 is more logical as 9.4% for 1.c4 and 8.6% for 1.Sf3
(the opening book without move transpositions).
But OK, FEOBOS take up one's new job in both graphical user interfaces (GUI).

febos by Frank Quisinsky

And here FEOBOS v5.0 opening books without move transpositions and "834" variants, danger for fast draws (3-fold-repetition).
If 3 of 5 engines evaluate with 0,00 ... position is reject. For an higher "contempt"!!

Opening Book 3 for Shredder Classic GUI

113.570 moves based on
23.398 lines without move transpositions / draw lines!
3 moves after A00-E99 ECO codes formed!

And the same for Chessbase Fritz GUI
