A hostage exchange is performed by transferring a piece from one's prison to the opponent's airfield, then selecting and releasing a piece from the opponent's prison and immediately dropping it onto an empty square on the board. The drop completes the turn. The piece transferred must be of equal or

variant. But a variant with two advantages. In the first place, it uses a single chess set, effectively pushing
Chessgi, with its requirement for two sets and the almost inevitable confusion that that causes (have you tried playing it over the board?) into limbo, except perhaps for correspondence
223:
only to a Q, R, B, or N that is available in the opponent's prison. The promoting player selects which piece to release and promote to; the pawn is transferred to the opponent's prison. If the promoted piece is subsequently captured, it retains the type that it had when entering prison.
144:
the freed man back into play on the board onto an open square. The man exchanged for the dropped man is transferred from the player's prison to the opponent's airfield. On any turn, instead of making a normal move, a player can drop a man from his airfield into active play on the board.
73:. Unlike shogi, the piece a player may drop is one of their own pieces previously captured by the opponent. In exchange, the player returns a previously captured enemy piece which the opponent may drop on a future turn. This is the characteristic feature of the game.

to the player's left. There should be a clear boundary between each player's prison and the other player's airfield. Captured men are not removed from the game but are held in the capturer's prison. Instead of making a normal move, a player can perform a

Black cannot take the white queen, because that capture would provide an imprisoned white queen for the white pawn to promote to, thus illegally checking themselves. But Black can threaten the white queen, and does so, while capturing a

Queen for bishop swap. To free their queen from prison, White would have to first capture Black's queen. But White's queen is in Black's prison, and so Black can sacrifice their queen any time, then promptly re-enter it via a hostage
557:
c7+ achieves nothing, as neither the queen nor the rook can be taken, as Black then exchanges hostages and mates on e1. If instead 21.Rxb4, Black has the crushing 21...Qd3, which threatens both (Q-N)N
708:
This is similar to pawn promotion rules in some forms of
European chess as before the rules of chess were standardized in the 19th century: "could only promote to a piece already lost".
46:
f7+ (transferring the black knight in their prison to Black's airfield, then releasing the white bishop from Black's prison and dropping it on f7 with check) to win Black's queen.
174:. (So, any piece can be exchanged to free a pawn; whereas only a queen can be exchanged to free a queen.) A hostage exchange cannot be refused by the opponent.
589:
Four checks (two plain, and a P for P prisoner swap and drop, and a Q for B disadvantageous prisoner swap and drop) chase the white king into the mating trap.
395:
White drops the pawn from their airfield. Black is not in check since White cannot promote, because there is no imprisoned piece to exchange the pawn with.
182:
A drop can occur as part of a hostage exchange, or directly from a player's airfield. The square dropped to must be unoccupied. Additional drop rules:

The opponent may not capture a Q, R, B, or N (since to do so would make the pawn eligible to promote, putting the player in self-check).
