It's a lot of fun
The A.I. isn't a total pile of shit like most games, in fact, it's rather good! It responds well to everything I can throw at it, and is a formidable opponent. I can say, with little pride, that if it weren't for the "undo button" I'd have lost miserably.
Only thing I didn't like was the "replay" button. I accidentally clicked it 3-4 times and sitting through your own idiotic movements and complaining about how you could have been better (this is just me people) is really irritation, and pretty much boring.
Anyway, good game of chess when you don't have anyone to play it with!
