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.

Rules

[Castling]

 Castling is possible when there is nothing between Rook and King, Rook is at a1/a10 or j1/j10, and King is at f1/f10. when castles, the King moves 3 squares in the direction of the Rook, and the Rook in that direction is placed directly in front of the King. for example, if King of f1 and Rook of a1 are castle, King is at c1 and Rook is at d1. If King of f1 and Rook of j1 are castle, King is at i1 and Rook is at h1. however, when castles, the 3 squares that the king moves to the side must not be exposed to the attack of the enemy piece.

 

[En passant]

 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 your next turn. this is called En passant. when capturing an enemy pawn as an en passant, it only goes 1 squares as when capturing other pieces.

 - Pawn on the 6th rank can capture enemy Pawn moved 2 or 3 squares, and Pawn on the 7th rank can capture enemy Pawn moved 2 or 3 squares.

 

[Promotion]

 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. When a promoted piece is captured, its promotion disappears.

 

[Drop]

 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 must move after it is dropped so that you can choose whether to promote it or not.

 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. (It is possible to check by dropping a Pawn and checkmate on your next turn. This is because it is not a checkmate as a dropped Pawn.)

 5. Even if a Rook or King moves or drops, castling is possible as long as they are in the correct position. Likewise, 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. Dropped Pawn can capture enemy Pawn as En passant on your next turn.

 

 White moves first, and Black moves next.

 There is no passing a turn.

 Stalemated player loses.

 If the same state occurs 3 times in a row, 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 3 times in a row, the Threefold repetition is established and the match becomes a draw. but if you make the same state 3 times as a repetitive check, you are defeated.

 - If a draw is made due to threefold repetition, the match is played again by swapping White and Black.
