It is also possible to replace the pawns with checkers. They would move just as they would in their native game: diagonal movement, taking multiple pieces, and of course the "kinging" piece exchange in place of the "queening" of pawns. This means that a player can have multiple kings, each of which must be taken for check-mate.
