With the move notations listing origin and destination on all moves, it eliminates one important type of move, found on variations of this game elsewhere. It is the ability to play the "switch"
Say the relative value of one important piece has been determined by your opponent ( not revealed, just determined. Example your 4 was blindly attacked by a 3. Opponent lost a 3 , and now has determined the value of your piece at 4 or greater)
I am not too good in describing how it is done, however here it is:
In a 4 square area, A1,A2,B1,B2, you have the one piece on one corner( say a1) and the other at the opposite corner( B2)(both must be pieces not revealed by a spy). One turn passes where these do not move, then each piece moves to one of the other corners. Now the opponent is not sure where the piece has moved to.


As I said, the move notation given, unfortunately eliminates the ability to do this.
I would like to suggest that the notation be simplified so that the "switch" may become possible.
