Now you're just making me feel stupid. 🙁


Edit 1:

If you capture the rook with the pawn to promote to queen, then you roko is captured by the king, and the new queen moves to c6 for the win.

1. a8=Q Kxc7
2. Qc6#

That's two moves, but that's not what you want I guess.

I don't see anything else that's quicker.


Edit 2:

1. Rc8 Kxa7
2. Rxa8#

Well, since it is Black to move:
0...Kxa7 1.b8Q#
0...Kxc7 1.bxaN#
0...Rxa7 1.Rc8#

Usually, Mate-in-1 problems are Retros (because a simple forward #1 is uninteresting).

White does not have the move in the diagram, because Black has no legal last move. Black can't give checkmate, so it must be that White mates against any Black move.

1...Kxa7 2.b8=N#
1...Kxc7 2.bxa8=N#
1...Rxa7 2.Rc8#

Hey! There's ilywrin. Welcome back. You beat me to the solution, but you got a variation wrong...

Oh, I really did get the variation wrong 😉 Thanks, BigDogg

No squatting in this thread. Get a room 😛

I am digging up old threads randomly. My solution (in 2) would be just:
Rc8+ KxN
RxR#
or:
Kd8 RxN
Rc8#
or:
Kd8 KxN
b8=Q+ Ka6
Qb6#
or even if I were drunk:
Rc8+ KxN
Qa5+ KxP
QxR+ Kb6
Rc6+ Kb5
Qb7+ Ka5
Ra6#
Sorry but I am bored with new ones and practicing my visualizing.

You can dig up old threads and study them without having to post, you know.

Good point. I'll do that. Thanks for the shrouded advice.
