Chess Variant: Checked Chess

Each player, either before or after their move, may place one captured piece on any unoccupied square on the board.

For instance, the White Player may check the black king on H8, then place a captured black pawn on H7 to block the king’s escape route. The Black Player may respond by placing a captured white pawn in the path of the piece checking his king (let’s say, a bishop), then moving the black pawn placed on H7 to H5.
