# Missing checkmates in one

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?

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.
• Do we have to start with the six moves you've provided? – ZanyG Mar 21 at 10:03

• I don't think "both" means what you think it means. :) – Rubio Mar 21 at 15:30

• I take this is "helpmate", so to speak? – Acccumulation Mar 22 at 14:51
