DIABALLEX

On each turn, a player can (optionally) do the following, in order:
1: Make two Halma moves.  They must be with different pieces.
   Only one of these is allowed by the first player on the first move.
2: Swap the King with a soldier provided that they are
   in the same line and with no enemy piece directly between them.
   This may be repeated successively with several different pieces.
The King cannot move by any other means.
GOAL - Win by getting one's king into the last row.
