My hacked-together solution, based on Bangkok (http://bangkok.rubyforge.org), is at http://www.io.com/~jimm/rubyquiz/quiz35/. I need to improve the board drawing routine and make the input more tolerant. Input for each move must be of the form used for chess game files (e.g., "f4", "Nf6", "Nxc6").

Egad that's short!
Unfortunately, I'm having trouble running it:
$ ruby -rubygems main.rb
./chessgame.rb:9:in `play': undefined method `board=' for #<DisplayListener:0x39e35c> (NoMethodError)
from main.rb:5

Oops. Remove the line
@listener.board = @board
from chessgame.rb. I've posted a fixed file and playchess.tar.gz file to http://www.io.com/~jimm/rubyquiz/quiz35/\. That's what I get for making a last-minute change without any tests. (Bangkok has tests, but not this simple playchess interface.)

You're going to wish I would shut pretty soon, but...
It's not notifying me of checkmates and looking at the code it seems like it should. Am I missing something?

No, I missed something. Bangkok reads pre-existing chess game files. Those files contain standard chess move strings that have modifiers that explicitly say "check" or "checkmate". Bangkok notifies the listener when it sees those; it does not look at the pieces and determine if there is a check or checkmate.
I think I'd better withdraw my solution. It isn't a solution to the quiz you posed. Oh, well, Only 15-20 minutes of my life wasted.

I'm sorry that I wasted *your* time, though.

I must say, I had seen Bangkok on RubyForge before and wondered about it. That is one unique concept you've got for a library there. It's very interesting and I'm glad I've now had an excuse to look a little deeper at it.

I still found it informative and I'm glad you sent it in. It is a good example for part II of this crazy idea of mine...
