    Place the Black King on the board where...

    a) It is in Checkmate.

    b) Where it is Stalemated.

    c) Where it will be mated in one move with White to play.

    Well done.

    Now it's your turn to post a puzzle (any theme) and the first solver has to post their puzzle.

    We keep doing this till one day (I calculate the year will be 2025) someone
    posts this puzzle again.

    SwissGambit, original

    Place the white King on the board...
    a) ...such that white mates in 1.
    b) such that white is checkmated.

    Rookbycrook seems to have it right.


    That is White in checkmate.


    White checkmates with 1. axb6 ep.


    Of course S.G. maye be wanting an explanation as to why it can be proved
    that en passant can be played in the 2nd diagram and not the first.

    Yep - an explanation's needed.

    Otherwise, why not put the wK on c4, as you did in your 2nd diagram? Works just as well as c5, right?

    We have to prove that the b-pawn was on b7 or b6. Yes?

    I might have to add more years to 2025...it will take me that long to explain this one.

    You have to prove that black's last move was ...b7-b5, and not a move with some other piece.

    The Black pawn on h4 has come from e7 so it cannot have taken from g5.

    The White pawn on c7 is the White b-pawn it has taken something from
    b6 so no Black pawn on b6. So the b-pawn is on b7.

    The white pawn could have taken (b6xc7), and then the black b-pawn could have stepped forward twice (...b6 and ...b5).

    You're trying to mate black.
