Try to mate the black king in one turn. But remember, you can promote the pawn to any piece.
 

 

This is a nice riddle I came across recently. I could not solve it myself, but once I learned of the solution I was blown away.

 

It definitely was a lot of fun though, so I thought I would share it with you.

 

Hint: This game is under old rules of chess which are not present today
