White has a certain advantage in tis game (less so in other Espionage variants). There should be a slight rule change: white can in its first move only move 3 pieces instead of 5, after that the game goes on as usual.
Avun Jahei: Good idea. I remember having suggested something similar at itsyourturn.com many years ago, but alas, it has been ignored. Very probably yours will be ignored too, since this site is not maintained or developed any more.
Avun Jahei: This could possibly work. it can give a slight advantage to black... even 1 less move could work as well. ultimately it comes down to whoever wants to attack first or whoever makes a blunder 1st ( blunder as in gambits his pieces or gambits sight of their piece first.)
