An 8×8 chessboard has 16 chess pieces on each side: king, queen, chariot, horse, elephant, and soldier. Each chess piece moves differently: the carriage moves in a straight line, the elephant moves in a diagonal line, the horse moves in the Japanese character, the rear moves in an arbitrary straight line, the king moves in a square, and the soldier moves forward but eats obliquely. The goal is to kill the other king.
Special rules: the king's chariot moves (the king and his chariot move at the same time), eating passing soldiers (the special eating method of soldiers), and changing soldiers (the soldiers reach the bottom line and become later or other chess pieces). AI uses minimax search and Alpha-Beta pruning, and the evaluation function considers the value and location of the sub-force.
After clicking the chess piece, highlight all legal moving positions, and click on the target position to move. Support repentance and chess recording (algebraic notation). The depth of AI search is adjustable. The greater the depth, the stronger the calculation is, but the slower the calculation.
An online chess game supports double and AI matches, and fully implements the moving rules of all chess pieces, including the transposition of the king's chariot and the promotion of soldiers.
