I'm still new here but I want to share the links which helped me make my own polyglot book, and other details about it.
1.Start here:
http://wbec-ridderkerk.nl/html/details/PolyGlot.htmlThis is the official site of "polyglot" by Fabien Letouzey. The instruction there will guide you through book-building,merging books and the proper use of polyglot adapter.
2. Marc Lacrosse is the main proponent who mastered the full potential of polyglot. Visit his two sites for the files and tutorials:
http://users.skynet.be/mlcc/chessbazaar/contents.htmlhttp://chessbazaar.mylivepage.com/fileIf you happen to know the strong performance.bin and varied.bin of the Fruit/Toga engines, he's the one who built it. Download his collection of ICC games, use pgn-extract to un-annotate/trim the pgn games and try your luck making your own books. Or you can visit Norm Pollock's website of pgn collections, recommended for book-building:
http://hoflink.com/~npollock/chess.html3. In case you want to get good polyglot books, Pavel Hase is a well-known Czech polyglot book builder. He also builds books for Loop, DeepSjeng, Romichess, Glaurung and his favorite -Spike.
You can find his works here:
http://www.chesspraga.cz/spikebook.htmHe has made a lot of polyglot books to test!
If you want some special compiles for polyglot without using cygwin.dll, pls. send me a note together with your hardware and OS -Windows only.
I hope this small note helps. Thanks.
