Checkerboard games {chess} can have one king, one queen, two bishops, two knights, two rooks or castles, and eight pawns for each side. Pieces capture by displacing opponent's piece. King can move one square in any direction. Queen can move any number of squares in any direction, with no jumping. Rook can move any number of squares on row or column, with no jumping. Bishop can move any number of squares on a diagonal, with no jumping. Knight can jump two squares on a row or column plus one square on a column or row. Pawns can move one square forward, with no jumping, and capture diagonally. Pawns can move two squares forward first time. Object is to capture king.
