[tslhczny] Home and away

Consider a chess variant in which pieces are stronger on their "home" side of the board than the enemy's side.

Rook turns into wazir in the enemy's camp.  Starting anywhere in the first 4 ranks, it can move at most to the 5th rank in one move, then single steps only. Perhaps it retains the ability to retreat quickly.

Bishop similarly turns into ferz.  Similar to rook, it can still do retreating ranged movements two ways diagonally backward.

Knight requires an empty intervening square, either a wazir or ferz move.

On the home side, it's quicker to reorganize your forces.  Rooks for example can range across the whole width side to side, assuming an open rank.

Defense becomes easier, likely making the game more boring.  How should this be counterbalanced?
