What is the best way to play chess via terminal?

Question

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.

Answer 1

You can save games with:

pgnsave FILENAME

This saves the game played so far from memory to a file.

You can find some documentation here: http://savannah.gnu.org/projects/chess/
