HARDEST PUZZLE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Sort:
I assume it's White to move and a1 is in the lower left corner.
If so, it's a mate in 4.
1.bxa8=Q+ Kxa8 2.Ka6 Kb8 3.Rc6 Ka8 4.Rc8#
Just an old puzzle, the white pawn promotes to a black knight and it's mate.
@Prashanth222000 - 1. bxa8=N+ Kxa8 isn't mate just yet.
What's difficult? Extremely easy.
@GuessWhoIAm: No, 1. b8=bN#, not 1. bxa8=wN+.
Yes^…but I'm wondering what makes it hard.
This is old and has been posted before

Look at both ways of promoting.. You can do b8 promotes to black knight instead of taking the rook...
1 move
Oh, I thought you meant promoting to White knight. XD

the white pawn promotes to a black knight????
Chet, that is not legal in real chess. But the only mate in 1 solution to this puzzle is that..

I think you must first get past letting go of the exclamation point on the title. Two or Three would make the point. :)
