@H.G.,
Thanks for providing the heuristics. I think I will implement this so it doesn't blindly trade it's way into a stalemate endgame thinking it is ahead. It wasn't what I was thinking of though. I'm wondering for which combinations of pieces the GUI should terminate the game and declare a draw. Any combination of pieces that can't be arranged into a checkmate position even if the opponent walks his king into a corner would be a good start (and probably sufficient.) But that could be hard to determine. Probably would have to start with a simple piece property that specifies if that piece with just a king can checkmate another king (your Mating Minor property) and then only detect 3-piece forced draws.
@Jeff,
Thanks, I will look into this. It's possible I didn't test with a completed game. As a work-around, you could just do one "take back move" so that the game is no longer finished. (First, be sure to uncheck "computer plays white" and "computer plays black" so it doesn't try to start playing when you take back a move.) I'm also unsure why it would give you an error and crash during a game. This was certainly tested. Is the computer thinking when you try to go back? That would certainly mess it up, although I think I put checks in place to prevent entering review mode when the computer is thinking. When you get this crash, can you use the button on the crash dialog box to save out the error long and email it to me?
