Here with a quick chess puzzle one of my friends gave me.
The puzzle is a bit interesting; it is White to move and not mate in 1, which is the reverse objective of the usual puzzle (hence the title). The puzzle is a legal position from the starting position. I also have a few hints, given to me by the same friend:
check the tags, it's not just a chess puzzle
Without changing the position of the pieces, how would it be possible for White to make a legal move that isn't checkmate?
Well, I... messed up the FEN. There shouldn't be a white pawn on a6 (or h3 with the intended answer). Now it's possible. I think.
