Dark chess is a game for two people. The chessboard is composed of 4X8 squares, and the chess pieces use 32 chess pieces. At the beginning of the game, all 32 chess pieces are covered face down, and the computer decides who will start the game first. After the first piece is turned over, the color of each player can be determined. Each player can choose to turn chess or play chess according to their own conditions. When playing chess, if the front, back, left and right are the opponent's pieces, and the level of the pieces is lower than your own, you can capture the opponent's pieces. The ranks of the chess pieces are: general (commander) > soldier (official) > bishop (xiang) > chariot (俥) > horse (傌) > pawn (soldier). However, generals cannot eat pawns, but pawns can eat generals. In addition, Bao (cannon) can't directly eat other chess pieces, but it can directly jump and eat other chess pieces, regardless of size, separated by a chess piece, and the distance is not limited. At the end of the game, if one side's chess pieces are all eaten up, the other side will be the winner of the game. If the two sides continue to take 50 steps and still fail to capture any of the opponent's pieces, it will be determined as a tie, and the two sides will be tied. Please note that during the game, if any party keeps making repeated steps without stopping, the computer will judge it as malicious behavior and end or stop the ongoing game.
