According to FIDE rules,
the pawn may move to a square occupied by an opponent’s piece diagonally in front of it on an adjacent file, capturing that piece.
So, what's in front of a pawn? I'll let you choose.
Find a minimal sequence of moves for the following board, such that one white and one black pawn remain after the sequence of moves is executed.
- Each pawn may only capture pieces of its own color
- Each pawn may face up, down, left, or right at the beginning
- Each pawn may only have one orientation for the entire sequence
- Each pawn may move to a square diagonally in front of it on an adjacent file/rank, capturing that piece.
A minimal sequence requires 62 moves.
