New SALC Opening Books and Positions  



The new SALC opening-books and positions by Stefan Pohl (idea and creation)

SALC was made for engine-testing and engine-tournaments (all engines must use the SALC-book, SALC is not for playing versus other books!!!)

SALC means (S)hort (A)nd (L)ong (C)astling: The SALC books were created out of human games (castling to opposite sides (if white played 0-0, black played 0-0-0. If white played 0-0-0, black played 0-0)), both queens still on board. No double games.
When using SALC, the chance for attacks towards the opponent king is much higher than using normal opening-books. Because of this, computerchess using this book, will bring more action and fun to watch (and a measureable lower number of draws), because the faster the computers get, the higher the quality of computerchess get and the higher the draw-rate in engine-engine-matches get...so the computerchess is in danger to die the "draw-death" in the near future.


You find 3 folders in this download-package:

1) SALC 500pos 2017: 500 SALC-positions (pgn and epd) which are 7.5 moves (15 plies) deep. Evaluation of
Komodo 11.01 in end-position (20 seconds, 3 cores, 2048MB Hash) in an interval of [-0.4,+0.4]
500 different positions

2) SALC 9moves book: 9 moves (18 plies) deep SALC-positions (pgn, epd, FritzGUI-book and ShredderGUI-book.)
Evaluation of Komodo 11.01 in end-position (20 seconds, 3 cores, 2048MB Hash) in an interval of [-0.5,+0.5]
5328 different lines/endpositions.

3) SALC 12moves book: 12 moves (24 plies) deep SALC-positions (pgn, epd, FritzGUI-book and ShredderGUI-book.)
Evaluation of Komodo 11.01 in end-position (20 seconds, 3 cores, 2048MB Hash) in an interval of [-0.6,+0.6]
30000 different lines/endpositions

From 1 to 3 the number of positions is getting higher (because more castling-moves to opposite sides are taking place, when the number of moves is higher)(1 is too small to create an opening-book). And from 1 to 3 the interval of the Komodo-evaluation is getting wider, which rises the number of positions, filtered out of the database, too.

Recommended book-settings in the GUI -> see the booksetting.jpg picture (settings there are without booklearning). IMPORTANT: Set the parameter "minimum games" to 0 (and in the ShredderGUI set Wins=0), otherwise the book will not work!!!

Enjoy this next step of chess-engine matchplay and testwork. Less draws, more spectacular games/mates, without distorting the test-results and scores !

Have fun! - Stefan Pohl (SPCC)
