Hostage chess .
How to play ?
The rules are the same as regular chess except for these changes for a refresher of those rules .
Check out this video .
Each player has a prison on the right side of their board and an airfield on the left .
Whenever you capture a piece , you place that piece in your prison on your turn .
Instead of making a normal move , you may perform a hostage exchange transfer one of your prisoners to your opponent's airfield to take an appropriate piece from their prison and place that piece on an empty space on the board .
This is called dropping a piece .
The peace transferred must be of equal or greater value than the peace released from prison .
The relative peace values are queen is the highest followed by rook .
Then bishop and knight are of the same level with pawn .
At the lowest level .
Therefore your ponds may move towards the center laterally around the circle or through the center or any combination thereof .
So long as the move puts them closer to the starting space of the opposing king than the space they are currently on .
This does not mean it has to be the closest space available just closer than what it currently is when a pa is in the center space , it may move out of the center to any of the seven spaces on your opponent's side of the board .
Then it proceeds with movement towards the starting space of the opposing king ponds still capture diagonally in front of them , which translates to being able to capture to either side of any space , they can move to any of your pawns on your half of the board that are adjacent to the center may capture to the center .
If there are no pieces available to promote to , then the pawn may not advance to the eighth row .
Furthermore , if your opponent's king is diagonally in front of the pawn and there are no available pieces to promote to , then the king is not in check as the pawn is unable to advance to the eighth row .
However , your opponent would also not be allowed to capture any piece that your pawn could promote to as that would immediately put the player in self check .
A dropped rook on a rook starting space may be used in castling .
So long as all the normal castling requirements are followed , you may drop a bishop on either color the first player to checkmate their opponent wins .
The bishop's diagonal movement travels through the opposite corner of the space the piece entered , you may not change directions mid move , the bishop may travel through the center to do so .
The bishop travels in a straight line across the center to the opposite color then diagonally in the same diagonal direction that it began .
The move with .
It is as if the two adjacent spaces of the center are the same space .
If the bishop started the move adjacent to the center , then it travels directly across the center to the other side , then it may travel diagonally in either direction towards the outside of the board .
A bishop in the center space can reach any space on the board in a diagonal outward line .
Unless its path is obstructed by another piece , the horse has the same movement as the knight , but it may not travel through the center space to the other side .
If the horse is on the middle or outer ring , in addition to its normal movement , it may also move to the center .
If the horse is in the center , it may move to any of the spaces in the two inner rings .
The horse moves directly to its space , passing over any piece in the way the diplomat which may be represented by a queen or another piece may move one space in any direction to any unoccupied space .
The diplomat may not capture pieces but instead may suborn them instead of moving the diplomat can suborn an adjacent enemy piece to your side .
Simply leave the diplomat stationary and replace your opponent's piece with the same piece of your color .
You now control that piece and all its abilities and may move it .
As soon as your next turn , you may not move a diplomat and suborn a piece .
In the same turn , you may only suborn one piece per turn .
Even if multiple pieces are adjacent , you may suborn any peace except for the king .
The diplomat does not put the king in check , the first player to checkmate or stalemate their opponent wins .
If the same position is repeated three times , then the game is a draw .
