Optional Rule: Fighting on a Grid

If you run combat on a grid, chesski may be required to move in a manner similar (but not identical) to the way they do in chess.

Pawns and Kings. Pawns and kings can move one square in any direction. Pawns can only attack creatures in a diagonally adjacent square, but kings can attack in any direction.

Rooks. Rooks cannot move diagonally.

Bishops. Bishops can only move diagonally.

Knights. Knights must move either two or four squares in one direction and half that distance in a perpendicular direction.

Queens. Queens can move freely.
