I've recently learned about gnu chess, but it's poorly documented, and I'm having difficulties:
- Setting a reasonable difficulty level;
- Saving an entire game to a pgn: it's only saving the last move;
How can I do this? Is there an e-book or a good tutorial I can follow?
Thanks in advance
Update (2/8/15): Actually, it's the version of gnuchess that's packaged with Debian 7 (6.0.2) that has a bug; after compiling 6.2.1 pgnsave worked normally.
