a2a3 gives me illegal move game over. What am I missing here?

Somewhat surprisingly (given the creator's regex chops) capital letters are not accepted. My guess is that your autocorrect changed the move to A2a3.

Bad news if you're almost done with a game and enter a move with the wrong case.

I'm on PC (firefox) and can reproduce it, no capital letters in my input

Hm. I don't get any errors unless I use a capital, and I get an error every time I do.
