Missing checkmates in one
$begingroup$
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:
- g4 e5
- f4 Be7?
- Nc3 Nc6?
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.
