Xiangqi: Chinese chess, duel

The game is played on a rectangular board of 9 by 10 lines. The shapes are set at the intersections of the lines. There is a river between the two central horizontal lines, which affects the movement of pawns, knights, and bishops. The two areas marked by two diagonal lines of 3-by-3 squares are called palaces. Kings and advisors cannot leave these squares. The first move is made by the red pieces.

The game can be played with artificial intelligence, together with another person on the same device, or with a rival online in multiplayer mode. You can also watch other players' games, act as a spectator, and offer your own version of the player's next move by making it on the board.

Shapes:
- The king can only walk one point horizontally or vertically within his palace. Kings cannot stand on the same vertical so that there are no pieces between them; moves that create such a situation are prohibited.
- The Advisor can only move 1 point in the diagonal direction in 1 turn. Like the king, he cannot leave the palace.
- The bishop moves diagonally by two points. Can't jump over pieces. Can't cross the river.
- The cannon moves like a chess rook. Captures the opponent's pieces only if there is exactly one piece between it and the attacked piece.
- The chariot moves to any number of available points vertically or horizontally.
- The knight moves to one point vertically or horizontally, and then to a point diagonally. It does not jump over the pieces, but moves in the plane of the board.: first horizontally or vertically, and then diagonally. If there is any piece at the intermediate point of the knight's move, it blocks this move.
- The pawn moves one point ahead. In the enemy's territory (across the river), it has the additional ability to walk sideways, also by one point. After reaching the last line, he walks only sideways.

Party Completion:
Check is an attack on the king by any piece. The player whose king has been given a check must defend himself against the check in return. Any other moves are forbidden to him. If there is no protection from a check, it is a checkmate and a loss. To protect against a check, you can either move the king to a point that is not under attack, or beat the attacking piece, or block its attack.
A stalemate is also a loss — the player's lack of legal moves.
The player who repeats the move three times loses.
