Ubuntu Linux and Chess -- using xboard to compare engines

I thought I would just make a quick post to say how to use xboard to play a game between two chess engines.  In another post later I will explore a better way of doing this, but I am going to just start with a simple game between stockfish (the strongest engine I have mentioned), and gnuchess (the weakest).

I had stockfish playing white and gnuchess playing black.  I started the game by typing this into a terminal window:

xboard -fcp stockfish -fUCI -scp gnuchess

Now remember what I said about xboard -- it's ugly and you sometimes need terminal commands, but it gets the basics done.

Anyway, after starting xboard and selecting Mode -> Two Machines, I ended up with this little gem of a game:

I don't want to say very much about it at the moment, except that stockfish is a clear winner in 25 fairly unimaginitive moves.  I also didn't use an opening book database and this is only one game.  But it gives you a fairly general idea.
