I also devised this chess variant of "paratrooper" chess. Board and pieces (construed to include pawns) are as in standard chess. Initial board orientation is as in standard chess. The board starts empty. Each player starts with a draw pile including all pieces of his color. Plays alternate with White playing first, as in standard chess. On each play, a player may elect to either move or drop a piece. A move consists of a legal chess move, with the following provisos: - Captured pieces are not returned to the draw pile and cannot thereafter be dropped. - Rules governing check, checkmate, stalemate, forced draws, and pawn promotion are as in standard chess, with a drop interpreted as a move. - Two-rank pawn moves, en passant capture, and castling are not permitted. A drop consists of placing a piece from the draw pile on one of the first four ranks. - The king must be dropped on each player's first play. - The king may not be dropped in check. - A piece may be dropped so as to block check.
