Missing checkmates in one












8












$begingroup$


Have you ever missed a one-move checkmate and immediately realized it after making your move? If you have, you just might have what it takes to crack this problem. Let's take an example:





  1. g4 e5

  2. f4 Be7?

  3. Nc3 Nc6?


enter image description here




In this example, black has already missed two mating moves: one with the queen (2...Qh4#), and one with the bishop (3...Bh4#). The goal is to find the smallest number of moves after which the same side has missed a mate-in-one with both a queen, a rook, a knight, a bishop and a pawn. Whoever finds the smallest number of moves wins.



Rules/clarifications:





  • The piece delivering checkmate is what counts. If you move a bishop to discover a mate by rook check, it's a mate by a rook. Mates by double-check are counted as both pieces.

  • Promoted pawns count as the promoted piece, not as a pawn.

  • You can use any moves from the starting position, not necessarily the same ones as in the example.

    I don't think "both" means what you think it means. :)
