the answer is bxc6
Can you post the proof? I can't find it myself.
There are only 2 apparently legal last move for black: c7-c5 or e7-e5 (you want another one? please tell us). However, if Pe5 were on e7 on the last move, how did Bh6 travel from f8 to h6 during the game? Well, it can't and therefore c7-c5 is the only legal last move!
the pawn could only promote on d1

Isn't Qd4 mate as well?
Haha, that's very cool!

This puzzle is not hard at all, but the rating they give to this puzzle is ridiculous. Black to move and win

So here is a serious mate in 1 puzzle, not obvious and not weird. That is to say, it is played by the chess960 rules which means that pieces may start in weird places on the back rank. Also castling may happen with king and rook in different places than usual. How is this "mate in 1"?
@Arisktotle, If it is black to play I don't se anything; if it is white to play then:
1) If white moves bottom up: c6#
2) If block moves bottom up: f5#
Because this is chess960 I cannot see a way to prove whether 1 or 2 is the case.
If you can't prove which side is on move, it is always white. But actually you can prove which side is on move. Just try to take back a legal "last move" for either side and see what comes up. If it turns out that black is on move, it is still white who checkmates in 1. The black starting move is extra.
Note: the coordinates are regular. I added them in the diagram!
Yes, that is correct, I didn't try to prove which side has the move, I just assumed it was white. So the correct solution is c6#, isn't it?
No.
But why? Black cannot castle, he is in check. Also, c6 is the only check for white.
the answer is bxc6
