Antoine,

Your'e welcome.  I find your proposed flipping rule quite interesting,
though the one you had is also playable.

I don't know if the modified cube rule is really needed in the opening
and middlegame. In general, hogging the pocket by putting a piece there
and leaving it for 20 turns is self-defeating, anyway.

But there is one type of endgame I would urge you to consider:

You have King and two Windmills vs. my King, two Bishops, and Knight. At
the moment, your Windmills are not adjacent to anything. If the pocket is
empty and there is no cube rule or you have the cube, you can use the
pocket to move your Windmills.  If there is a cube rule and I have the
cube, your Windmills are immobile if I can keep your King away from them.

If there is no cube rule and it's my move I can immobilize your
Windmills
by putting the Knight in the pocket and leaving it there.

Do you want this type of endgame?


I have a set of rules about the pocket you might want to consider:

1.  If the pocket is empty either player may move a piece into it except
as provided by rule 5.
2. When a piece has been in the pocket for three turns, its owner must
move the piece out of the pocket on the next turn. 
3. If the player is in check when rule 2 applies and he can relieve the
check by moving the piece out of the pocket, he must do so.  
4. If the player is in check when rule 2 applies and he can't relieve
the
check by moving the piece out of the pocket, the player makes any move
that relieves the check and must move the piece out of the pocket on his
next turn.
5. When a player moves a piece out of the pocket, he may not move this or
another piece into the pocket until the pocket has been empty for three
turns or the opponent has moved a piece into and out of the pocket.

Three turns is a guess, you will want to experiment.
