Hello There,

SCCT Book ChampionShip IV is already started:
http://www.sedatc...ge_id=1231

The Current Leader: CEGT book - My Congratulations to CEGT Team !

Frankly,
This time, I am very disappointed with WorldChampions book's performance
Unfortunately currently its ranking is at last place (!
It looks like Houdini 4 suffers via WorldChampions book
For example in the previous tour, the same book finished as 9th place

Note that Book Registrations (up to 8 moves) are acceptable !

In case of interest to participate, please send your book to my E-Mail:


The registration date: 17 - 19 December 2014
Note: Registered books will be tested in gauntlet mode !

You have choice to prefer Hoidini 4, Komodo 8, Stockfish 5

I hope to see many book registrations in the current event...)!

Note also that,
In the beginning of the tournament, I set Stockfish 061214 for all book participants
But later I've change my mind, because I noticed nearly 90 % draws
That's why later I switched to 3 different engines:
Houdini 4 (H4)
Komodo 8 (K8)
Stockfish 5 (SF5)

For example after that moment,
The draw percentage is dropped to approx. 55 %

About book settings,
All books are playing with optimized book settings: min games: 3 up to 8 moves
Exception for Baracuda 2014d, it is s playing with Book Author's recommendation

As I mentioned before:
Here are the new conditions/rules for the current book tournament,
To be as book participant: minimum 100 opening lines are required
*For example, minimum 50 as Whites and 50 as Blacks openings
or 30 as Whites and rest 70 opening lines as Blacks
Note: I don't request totally different openings...
For example, your favorite openings can be English, Spanish, Sicilian...but not exactly same and a few lines
Otherwise it will be too boring to see only B90 at 8...h5 or D43 etc...

Please note also that,
Up to 8 move book openings are allowed
Book Settings: recommended by the Book Authors

There will be qualifications for the current playing books:
So each participant will be played 200 games per player
And after that, only the Top 5 books will be continued of participating
The new registered books will be tested against Top 5 books

The books will be tested with Learning OFF (to see more various openings)
The rest conditions will be same as previous one (SCCT CS III)

And here are some of the opening books, which are currently running:
Baracuda 2014d (by Marijan)
CCRL (based on Top engine games played in CCRL)
CEGT (based on Top engine games played in CEGT)
FCT (based on Top engine games played in FCT)
