A value
In draughts, a single piece cannot take a double piece directly. However, if a single piece is in a position to jump over an opponent's single piece that is adjacent to a double piece, it can capture that single piece, but it cannot capture the double piece itself unless it is promoted to a king and is in a position to do so. Therefore, a single piece can only take a double indirectly by first capturing a single piece.
In draughts, a single piece cannot directly take a double piece in a single move. However, if a single piece jumps over an opponent's single piece that is adjacent to a double, it can then continue its jump over the double piece if the position allows for it. Thus, the single piece can indirectly take a double by jumping over a single piece first.
A single 'piece' of sand is called a 'grain'.
