Hardest Checkmate in 1

why where the heck is the king!

The Answer is pawn takes e5 with en passant.      If you do queen to f6, the king can take the knight.

OMG, this is the en passant Mate-in-One thread that refuses to die. Someone call Rick Grimes please.

???

white to checkmate in one. white is on bottom. black on top. so no tricks.

hint: thiss been the hardest checkmate in one since 1862 and theres actually TWO solutions !!

PxN (R) or (Q) ... that’s TWO 🤔.  I think thou wast editing whilst I was responding 🙂

Cool.

Back to the original puzzle ... I don’t see dxe6 (ep) even being a check, so how can it be a checkmate? What am I missing?

sorry. i take it all back ! i set it up wrong. heres the right way. and theres only (1) solution.

cool

Wrong puzzle. You have to show the last move. Puzzle solved with condition apply.

I can see mate i two moves: white plays Bxe5 black does  pawn xe5 and white does Qxe5#

Rick Grimes is the main character of The Walking Dead.

It was a way of saying this thread keeps coming back from the dead.

#48 is easy. But I am not going to spoil the fun

Clue: "History".

There needs to be a Black rook on a8.

Edited:

Mate in four

ur setup is right in #54. TY eric  . but no its not checkmate in four. Its still checkmate in 1. and ill give u the ans so u can have breakfast.

1. pb8 (black Kn) #

remember ?...i said 1862. thats cuz u could promote to any piece (except a pawn) of either color up til then. William Steinitz fought very hard against this rule change but lost his bid. so now of course u hafta promote to Q, R, Kn, or B that is ur color only. sad.

uhhhhhhhhhhhh...
