I have some suggestions for some really new game ideas--some lines of action variation-rules are the same as the regular game,plus some changes.
( I just dreamed these up now)

lines of action-pool shot:
a lines of action variant in which a player can move a piece to a square which is occupied by an opponent's piece, it is not remove from the board.but it is moved to the edge of the board in a straight line along the the route the piece was moved.If another piece is in the way,it jumps over it and continues to the edge.If a piece exist at the edge,that piece is bumped off the board and can be re-entered to only that spot on the board in place of a turn.this can not be done if the spot is occupied.

lines of action-clone:
a lines of action variant in which a player can move a piece to a square which is occupied by an opponent's piece, it is not remove from the board.but is changed to the opponent's colour.

lines of action-antimatter::
a lines of action variant in which a player can move a piece to a square which is occupied by an opponent's piece, it is not remove from the board.but both pieces are removed from the board.(the attacking and the defending piece)

I hope our fearless leader sees these,some feedback would be interesting.
