Dragonfly (1982)

"Dragonfly is a Chess variant played on a 7x7 board using most of the pieces of orthodox Chess, but not a Queen. The setup position puts the king in the center of the first row, with the Bishops left and the Knights to the right. Pawns have no initial double move, all other pieces move as in Chess. Castling is allowed, too. In practice, two sets of pieces are necessary to execute the game's Shogi-like drops: captured pieces are held in reserve and can re-enter later under the capturing player's control. Pawns which reach the opposite side promote to a unit in the opponent's reserve (!), if there is one, essentially re-capturing the reserve unit. Captured pawns cannot be dropped and remain out of play. "
