I was six-years-old when I received my first chess set. It was one of those with the cardboard chessboard and manila and black plastic pieces. I’m sure it came with a rulebook, but I doubt I read it. Perhaps I should have.
There are six pieces in chess. Each piece has its own movement restrictions. The smallest and seemingly the most worthless piece is the pawn. It can move to one unoccupied space on every move with the option to move forward two squares on its first move provided both squares are also unoccupied. It can only move forward unless it is attacking in which case it must move diagonally to capture an opponent’s piece. And, the pawn has a special shape-shifting move in which it can be promoted to any chess piece if it makes it to the eighth rank (the opponent’s back row). That’s it. Or, so I thought. Enter the en passant.
