Let's play a game of chess, i'll make the first move: rook to a3.
Sounds like fun! However, that's not a legal first move in a game of chess. If we're starting from a different position, could you please provide me the board state in Forsyth-Edwards Notation (FEN)?
Good catch. How about we start off with a mate-in-one puzzle? It's your move as black. The FEN is `8/8/K7/2k5/8/8/8/1q6 b - - 0 1`.
Ah, I see that it's a mate-in-one puzzle! In this position, I can simply move the queen to b6, which delivers checkmate to the white king. So my move is: Qb6#.
