I'll update the Chess Bit; that one takes a while to program. You might have noticed that the pieces don't always move. Once I get that down, you should have an easier time figuring it out.
Chess Calculators? Geeze. Way to make me feel smart. I felt embarrassed that that three-move checkmate took me more than an hour to figure out when it was first given to me by my grandfather. He didn't think I could do it, though!! Hahaha.
