It takes a lot of shortcuts, works with just the right lightning, etc., but worked great as a proof-of-concept :)
We got away with not identifying the pieces by just detecting the color, assuming the game started from the initial position, and assuming only legal moves (the whole game is unambiguous using these assumptions).
It's all old-school computer vision with hand-written features, and I'm pretty confident there is tons of low-hanging fruit, but who has the time.
