Special moves in chess include castling, en passant, and promotion. Castling allows the king to move two squares towards a rook on its original square, then the rook moves to the square next to the king. En passant is a pawn capture that can only occur immediately after a pawn moves two squares forward from its starting position and lands next to an opponent's pawn. Promotion occurs when a pawn reaches the opposite end of the board and can be exchanged for a queen, rook, bishop, or knight. These special moves add strategic depth and complexity to the game of chess. **
