Keys "s"=save "l"=load "b"=back once
Frank Maus, 1924. Pieces may ride pawns to the end ranks. The combined unit is a "chesser" because a checker can be used in place of a pawn on a chessboard. The piece, but not the pawn, can separate anytime with a normal move.
These are simple illustrations rather than strong opponents.
