But why? Black cannot castle, he is in check. Also, c6 is the only check for white.

EvinSung got it right but he only gave part of the answer. You can prove it's blacks move because there is no legal last move for black - in chess960 or standard chess. When black starts he has several different options (castling is one of them) but white can checkmate against all of them!

I don't think #361 is correct. One reason is that blacks last move could have been Kg7-h7 moving out of the check.

EvinSung

nf6 x h7

The pawn on a3 started in the e file because the pawn on b5 started on the a file so it actually came from b4 and thus it wasn't blacks last move. For the other pieces there is nothing tricky, the last move black made was g5.

Meaning what? Black has 6 legal forward moves. What are the other mates?

Arisktotle

In #366 blacks last move could have been Kh8xNh7. It's still legal.

That's one white unit too many! Illegal.

Solution(highlight):
Due to the fact that the black king and queen are on the wrong colour, the pieces must have come from the other side of the board. So black can't take the knight as pawns can't move back!

White to move and find a move that is NOT checkmate. Good luck!

Rc6, since it unpins the black rook allowing it to take the bishop on h7
