Pandemonium (Surajang修羅場)
It is a chess variant that mixes Marshal and Cardinal of Capablanca chess, and Crazyhouse rules. However, I adjusted the position of the piece and the size of the board so that it feels close to the FIDE chess, and some of the rules of Crazyhouse were refined. And i combined Xiangqi's General face-off rule and Janggi's Setup change rule.
Setup
(Original Board)
- Based on the picture above, the file(vertical squares) is from a to j from left to right, and the rank(horizontal squares) is from 1 to 10 from bottom to top.
(Western Board)
R N B Q K M C B N R P P P P P P P P P P - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - P P P P P P P P P P R N B Q K M C B N R
The red letter indicates that the piece at that location has been promoted. Queen(奔) and King(陽/陰) are pieces that are not promoted.
Pieces
Rook, Bishop, and Knight have additional King's move when promoted. Marshal and Cardinal become the same as Queen when promoted. King and Queen are pieces that are not promoted.
Pawn (P. Bo步) : Moves one square orthogonally forward but cannot capture with this move. Captures a piece diagonally forward one square to the left or right. Promotes to Gilding.
- Pawn on the second rank can move up to 3 squares orthogonally. Pawn on the third rank can move up to 2 squares orthogonally.
Gilding (G. Do鍍) : Moves like a Queen.
Knight (N. Gi騎) : Moves one square orthogonally and then one square further diagonally. It can pass pieces. Promotes to Scepter.
Scepter (S. Gyu圭) : Moves like a Knight or a King.
Bishop (B. Gak閣) : Moves any number of squares diagonally. Promotes to Horse.
Horse (H. Ma馬) : Moves like a Bishop or a King.
Rook (R. Bi飛) : Moves any number of squares orthogonally. Promotes to Dragon.
Dragon (D. Yong龍) : Moves like a Rook or a King.
Cardinal (C. Ye猊) : Moves like a Bishop or a Knight. Promotes to Whole.
Whole (W. Jeon全) : Moves like a Queen.
Marshal (M. Su帥) : Moves like a Rook or a Knight. Promotes to Apricot.
Apricot (A. Haeng杏) : Moves like a Queen.
Queen (Q. Bun奔) : Moves like a Rook or a Bishop.
Bright/Dark (K. Yang陽/Eum陰) : Moves one square orthogonally or diagonally. White player has Bright, and Black player has Dark. When called without distinction between Bright and Dark, it is simply called King王. (therefore, in notation, Bright and Dark are written as same K.)
- The state in which your King is attacked by enemy piece is called check. if your King has no way to get out of the enemy's check on that turn, call it checkmate and you are defeated.
Rules
<Basic Rule>
Bright player(=White) moves first, and Dark player(=Black) moves next. They moves alternately.
There is no passing a turn.
Before beginning the game, both players can change the position of their Bishop and Knight. However, there must be 1 Bishop and 1 Knight on the left side of the King, and also 1 Bishop and 1 Knight on the right side. Bright player makes the setup first, and then Dark player makes the setup.
- Therefore, there are a total of four setups.
NB - BN : Inner Bishop Setup
BN - BN : Left Bishop Setup
NB - NB : Right Bishop Setup
BN - NB : Outer Bishop Setup
(Of course, both players don't have to have the same setup.)
<Castling (安宮)>
1. Castling is possible if King and Rook are at the starting point and there is no piece between them.
2. When castling occurs, the King moves 3 squares to the left or right, and the Rook in that direction moves to the opposite side of the King and is placed right next to the King. for example, if Bright of e1 and Rook of a1 are castle, Bright is at b1 and Rook is at c1. If Bright of e1 and Rook of j1 are castle, Bright is at h1 and Rook is at g1. Likewise, if Dark of e10 and Rook of a10 are castle, Dark is at b10 and Rook is at c10. If Dark of e10 and Rook of j10 are castle, Dark is at h10 and Rook is at g10.
3. Castling is impossible if the King is attacked, or if even one of the three squares the King has to go for castling is being attacked by an enemy piece. Castling is possible if only Rook is attacked.
4. Castling in the direction of King are called Kingside castling, and castling in the direction of Queen are called Queenside castling.
- Kingside castling : 王側安宮 (In notation, O-O-O)
- Queenside castling : 奔側安宮 (In notation, O-O)
<En Passant (通過捕獲)>
When an enemy Pawn moves 2 or 3 squares to evade a friendly Pawn's attack point, that friendly Pawn may capture that enemy Pawn on next your turn. this is called En passant. When capturing the enemy pawn as en passant, it moves 1 square diagonally forward as usual.
- En passant is only possible with friendly Pawns on the 6th or 7th rank. In other words, friendly Pawns on the 8th rank is impossible to en passant.
<Promotion (昇進)>
1. Pieces that reach the last(10th) rank may be promoted. but Pawn that reach the last rank must be promoted. pieces that are not promoted on the last rank may be promoted again after moving.
2. A piece that has been promoted cannot be returned to before promotion.
3. When a promoted piece is captured, it goes back to before promotion. That is, promotion is initialized. Therefore, when dropping the piece, you must drop it in the state before promotion.
4. Pieces can be promoted even when leaving the last rank. but a piece that has not been promoted when it leaves the enemy's last rank cannot be promoted until it reaches the last rank again.
<Drop (投入)>
1. You can drop a piece you captured on any empty square.
- Only one piece may be dropped on the board per turn, and this must be done instead of moving a piece on the board.
2. The piece cannot be promoted as soon as it is dropped to the last rank. A dropped piece needs to move after it is dropped if it wants to promote.
3. Pawns cannot be dropped on the first(1st) rank and last(10th) rank.
4. You can check by dropping a Pawn, but you cannot checkmate by dropping a Pawn. Of course it is possible to make a checkmate by moving the Pawn on the board.
- That is, When you drop a Pawn, if the dropped Pawn is protected from the frendly piece's attack point, and enemy's King cannot avoid the Pawn, you cannot drop the Pawn at that point because a Pawndrop checkmate is established.
5. Even if the Pawn is dropped or moved, it can move up to 3 squares on the second rank, 2 squares on the third rank.
6. Even if a Rook is dropped or moved, castling is possible if the Rook is at the starting point. Likewise, even if a King is moved, castling is possible if that King is at the starting point. Of course, it requires a starting point, so King can only castling in the e-file.
<Stalemate (膠着狀態)>
A player who cannot move or drop a piece loses the game.
<Kingcheck (王將)>
Two Kings cannot face each other. If each other's Kings are in the same file or in the same rank, and there are no pieces between the two Kings, they are considered facing. Therefore, the player that created the situation where Bright and Dark would face each other loses the game.
<Threefold repetition (千日手)>
If the same state occurs 3 times, it is a draw. that is, if the position of the pieces, the type and number of pieces caught, and the turn are exactly the same three times, the Threefold repetition is established and the match becomes a draw. Even if it does not appear in a row, if the same state occurs 3 times in a match, threefold repetition is established and the match becomes a draw. but if, on a threefold repetition, one player has been checking on every move since the previous occurrence of that position, that player loses the game.
-When a draw is made by threefold repetition, the match is played again by swapping White and Black.
