U have to place the black king so white can mate in 1.
Black king on c8. cxb8=N#
cxb8 choose Knight? (King on c8)
cxb8=N#
Well assuming you're looking at it from the black side of the board, the only way for white to mate in one would be to have the black king at f1. The move is fxg1=N#. The rook has him in check and controls f2, the knight on g2 covers e1 and is protected by the pawn on h3, and the new knight on g1 covers e2 and is protected by the rook on h1.
I think.
Not quite. This is a deductive puzzle, and there's only one way to reach the position shown. The black king was previously on c8, and moved to d7 - Kd7+. So now it is white's move, and he can respond (as several have pointed out) pxb8, underpromoting to N#.
EDIT: I went back and reconsidered, and there are some strange (but possible) sequences that place the black King on c8. The move is still pxb8 Underpromoting to N#, but there are actually two possible locations for the black king.
Aren't we simply talking about the same move from opposite sides of the board? And there was nothing said about how the position was gotten, just that that was the position and you had to put the king somewhere to mate in one.
looks like cxb8=N works for king on d7 too

If the board is flipped, you cannot promote a white pawn - they would be moving in the opposite direction.
There are two ways of looking at the puzzle. In one way, you are simply looking for a location where the black king can be mated in a single move. But I don't think that's the proper way of looking at it. The correct way is to find a position that the black King could be in, AS A RESULT OF LEGAL MOVES, and then mate him in one move. Turns out that there are at least two possible solutions for that.
Please note that I am NOT arguing with what you said. If you interpret the puzzle as you did, then Yes, you are correct. I did not, and do not, interpret the puzzle that way.
This time, it is the Black king who has been turned invisible! Despite this fact, White should still be able to Mate in one. What is the move?
