What command line is he talking about in here? Need Help in making a good Book for Shredder. Book Making ----------- *** NEW *** You can compile a PGN file into a binary book using PolyGlot on the command line. At the moment, only a main (random) book is provided. It is not yet possible to control opening lines manually. I am working on it though. Usage: "polyglot make-book <options>". "make-book" options are: - "-pgn" Name of the input PGN file. PolyGlot should support any standard-conforming file. Let me know if you encounter a problem. - "-bin" Name of the output binary file. I suggest ".bin" as the extension but in fact PolyGlot does not care. - "-max-ply" (default: infinite) How many plies (half moves) to read for each game. E.g. if set to "20", only the first 10 full moves of each game will be scanned. - "-min-game" (default: 3) How many times must a move be played to be kept in the book. In other words, moves that were played too rarely will be left out. If you scan full games "2" seems a minimum, but if you selected lines manually "1" will make sense. Example: "polyglot make-book -pgn games.pgn -bin book.bin -max-ply 30". Building a book is usually very fast (a few minutes at most). Note however that a lot of memory may be required. To reduce memory usage, select a ply limit.
