Captured pieces become prisoners and lose their promotion, guarded on your right. You can use your turn to put them back into play. A player can either move one of his pieces or drop a prisoner back into play on his behalf.
A pawn can’t be dropped on a column with an unpromoted pawn of the same color.
A pawn can’t make an immediate checkmate when dropped. It is allowed for other pieces.
A piece can’t be dropped is no subsequent move is possible, so a pawn cannot be dropped on the last line.
