Diagonal Move Rules

A number of chess pieces move diagonally. The Bishop is the chess piece that only moves on diagonals, but Queens can do the same diagonal moves as Bishops (as well as doing the up, down, and sideways moves of Rooks). Kings also move 1-square diagonally, as do pawn capture moves.

Diagonal moves have the pieces staying on the same color square. This means that Bishops always stay on the same color square as they started on.

Chess squares are considered to be joined at the corners for a diagonal move. This means that diagonal moves can thread their way between any pieces that are on the squares adjacent to the diagonal (on opposite color squares).
