Pandemonium (Surajang修羅場)

It is a chess variant that mixes Marshal and Cardinal of Gothic Chess, and Crazyhouse rules. However, some of the rules of Crazyhouse were refined.

Pieces

 - Rook, Bishop, and Knight have additional King's move when promoted.

 - Pawns move like a King when promoted.

 - King is the only piece that is not promoted.

 - Cardinal, Marshal, and Queen are treated as promoted pieces. These three pieces start with promoted state.

 

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 Guard.

 - Pawn on the second rank can move up to 2 squares orthogonally.

Guard (G. Cho哨) : Moves like a King. (Guard is a non royal piece. So even if the Guard is captured, the game is not lost.)

Knight (N. Gi騎) : Moves one square orthogonally and then one square further diagonally. It can pass pieces. Promotes to Scepter.

Scepter (S. Hol笏) : 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.

Alfil (A. Yu遊) : Moves 2 squares away diagonally. It can pass pieces. Promotes to Cardinal.

Cardinal (C. Ye猊) : Moves like a Bishop or a Knight.

 - It is the only piece that can make a checkmate alone.

Van (V. Jeon前) : Moves 2 sqaures away orthogonally. It can pass pieces. Promotes to Marshal.

Marshal (M. Won元) : Moves like a Rook or a Knight.

Ferz (F. Sa士) : Moves 1 square diagonally. Promotes to 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宮. (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將. if your King has no way to get out of the enemy's check on that turn, call it checkmate執 and you are defeated.

 

Rules

<Basic Rules>

 Bright player(=White) moves first, and Dark player(=Black) moves next. They moves alternately.

 There is no passing a turn.

 Setup does not change. In other words, you cannot change the position of Knight or Bishop like Janggi.

 

<Castling (安宮)>

 1. Castling is possible if King and Rook are at the starting position 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 clings to the opposite side of the King. for example, if Bright of f1 and Rook of a1 are castle, Bright is at c1 and Rook is at d1. If Bright of e1 and Rook of j1 are castle, Bright is at i1 and Rook is at h1.

 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. (Unlike King, Rooks used in Casting do not have these constraint. In other words, even if Rook is being attacked or the path that Rook must go through for casting is being attacked, only the conditions are met, casting is possible.)

 4. If Rook levaves the initial position by moving or being captured, it is no longer possible to castling in that direction. And when King leaves the initial position by moving, castling is no longer possible at all. Therefore, Rook and King must not be moved or captured for Castling. And castling is also considered a kind of move, so castling is only possible once per player.

 - Of course, castling with a dropped rook is impossible.

 5. Castling in the direction of King are called Kingside castling, and castling in the direction of Queen are called Queenside castling.

  - Queenside castling : 遠安宮 (In notation, O-O-O)

 - Kingside castling : 近安宮 (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 : 成)>

 1. The 7th rank and 8th rank is called Enemy camp. Pieces that reach the enemy camp may be promoted. but Pawn that reach the 8th rank must be promoted. pieces that are not promoted on the enemy camp, 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 enemy camp. but a piece that has not been promoted when it leaves the enemy camp cannot be promoted until it reaches the enemy camp again.

 5. there cannot be more than one promoted piece with the same move.

 - For example, if a Rook is promoted to become a Dragon, your other Rooks cannot be promoted.

 - However, the only promoted Pawn can have more than one on the board.

 6. Cardinal, Marshal, and Queen are treated as promoted pieces. So, if Cardinal, Marshal, and Queen are caught, their promotion is canceled and they become Alfil, Van and Ferz respectively. Of course, Alfil, Van, and Ferz can only promote one piece each.

 

<Drop (投入 : 打)>

 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 enemy camp. A dropped piece needs to move after it is dropped if it wants to promote.

 3. Pawns cannot be dropped on the last(8th) rank.

 4. Pawns can drop on 1st rank, but can only move 1 square on 1st rank. Only in the 2nd rank can pawns advance up to 2 squares.

 5. 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.

 6. Even if the Pawn is dropped or moved, it can move up to 2 squares on the second rank.

 7. Unlike Shogi, Pawn can be dropped onto the file where Pawn already exists.

 8. A dropped pawn is not captured en passant immediately after the drop.

 

<Stalemate (膠着狀態)>

 If a player can no longer move or drop a piece, the game becomes a draw.

 

<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 captured in each other, and the turn are exactly the same three times, the Threefold repetition is established and the game becomes a draw. Even if it does not appear in a row, if the same state occurs 3 times in a game, threefold repetition is established and the game becomes a draw. (However, depending on whether Castling or En passant is possible or not, the possible moves differ even if the position of the pieces, the type and number of pieces captured in each other, and the turn are the same. These states are not considered to be the same. That is, it is considered a different state.)

 - But, a threefold repetition with perpetual checks is illegal, and results not in a draw but in a loss by the checking player.

 - When a draw is made by threefold repetition, the game is played again by swapping White and Black.
