Makruk: Thai Chess

Makruk: Thai Chess is a board game from Thailand that shares similarities with chess. It is believed to have directly evolved from the ancient Indian game Chaturanga, which is regarded as the predecessor to modern chess. In Thailand, this game enjoys greater popularity than traditional chess.

The board size is identical to that of traditional chess, featuring an 8 × 8 grid. The initial setup mostly mirrors that of classical chess, with two key differences: the white queen is positioned on the e1 square, and the white king on the d1 square (meaning each king is to the left of its queen from the player's perspective); the pawns are placed on the third rank for the player (white on the third rank and black on the sixth).

The moves of the king, rook, and pawn are similar to those in chess: the king moves one square in any direction—horizontally, vertically, or diagonally; the rook can move any number of squares along a row or column; and the pawn advances one square forward or captures one square diagonally forward.

This game can be played against artificial intelligence, with another person on the same device, or against an opponent online in multiplayer mode.

Piece movements:
The king moves similarly to European chess, but there is no castling (moving the king towards the rook).
The queen moves only one square diagonally.
The rook moves any number of squares vertically or horizontally, as long as its path is clear.
The bishop moves one square diagonally in any direction or one square straight forward.
The knight moves in an L-shape: two squares in one direction and then one square perpendicular, or vice versa, akin to European chess.
The pawn moves one square forward vertically and captures one square diagonally forward, just like in European chess. A pawn can only promote to a queen equivalent upon reaching the sixth rank.

Winning conditions:
The objective, as in classical chess, is to checkmate the opponent's king. A stalemate results in a draw.
