Support for chess engine opening books #123

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I don't know if pychess supports this already or not, but for several chess
engines, including gnuchess and crafty, you can install opening books which
pychess could take advantage of.

It would be nice to have converters for the different engines opening books.
I've been looking at the crafty source code, and it might be doable.
Gennerelly a better openingbook, with more than 2000 kasparov games, would be 
nice.

Maybe we can add support for "OwnBook" and "Book File" options for UCI engines.

Another enhancement can be adding polyglot format book support:

I just saw this CTG book reader code:
https://github.com/AaronBecker/daydreamer/blob/release/book_ctg.c
(An older unofficial spec 
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?pid=26942 may clarify.)

PolyGlot is the most popular open format, used by SCID and many engines. It has 
good FOSS book-generation tools.
CTG ChessBase's closed format. It's the most popular among book-makers; many 
offer free (gratis) high-quality books.

If we support these two formats and let the user pick a book file, I think we 
can close the issue.
I'm also in favor of killing the existing SQLite book format and book-making 
code.

Yup, let's support PolyGlot first.
If the api good enough, people may contribute code for the rest.
Adding CTG as well is a good test, that the api isn't PolyGlot centric.

There is a new topic on TalkChess: Polyglot keys for chess variants.
http://talkchess.com/forum/viewtopic.php?topic_view=threads&p=482216&t=45121

And the new extension suggested by H.G.Muller(author of Winboard):
http://hgm.nubati.net/book_format.html

This can be interesting when PyChess will support more variants.
