Helpmate in 2

    Hi everybody, here is a special chess problem. It is a helpmate in 2 and also a special condition: Andernach chess.

    Helpmate means that black plays first, and black and white cooperate to mate black.

    Andernach chess means that if you capture a piece, the piece you captured with, will turn the other color. Like this: White plays 1.Rxc5=bR. So the rook on c5 turns black. But if he captures with a check, the color still remains the same.

    Here is the puzzle: Helpmate in 2

    It's black to move. It's in the description, but I forgot to set the diagram on black to move... Now it's fixed Wink

    Does checkmate count as check?

    There is nothing in Andernach Chess that says the piece doesn't change color in the event of a check. Moves like Rc6xa6(=wR)?? are illegal self-checks.

    Sol: 1.Rxc5(=wR) Rc4 2.Ka4 Ra3#
