No, a non-king piece in checkers cannot jump backwards. Non-king pieces can only move forward diagonally and can jump over an opponent's piece in a forward direction. Only king pieces, which are obtained by reaching the opponent's back row, have the ability to move and jump both forwards and backwards.

In checkers, you cannot jump backwards over an opponent's piece. Jumps can only be made forward diagonally over an adjacent opponent's piece to capture it. However, once a piece is kinged, it can move and jump both forward and backward.
