Chess 68 is a game created by myself, basically in order to give more depth to standard chess and imprevedibility.
Experienced players can continue to use their opening strategies because new pieces get in action only after several moves, in order to give them the necessary space to walk outside.
 
It looks like standard Chess, with the following modifications:

• 4 more squares linked to the 4 corner squares (idea taken from "Omega Chess"), these squares takes the coordinates as their ranks and files were present and contiguous: z0, i0 for white; z9, i9 for black. These added squares modify drammatically the standard finals theory and minimum material needed for mating. i.e = Lonely Rook now is not sufficient if the opposite king safely reaches corner squares; in the contrary two knights, now taking advantages of corner squares, can force mate !
   
  
• 2 more pieces:
   
  The Prince: Moves like a king. Can cover up to 8 squares and it's valued 3 pawns. Its power is maximum when used in defensive tasks particularly for protecting its own king. In the downside, its slow moving and quite far position at the start force it to move outside later. Like all the standard pieces except for the Knights, Prince must wait the development of the nearby Rook (usually by castling) before going into action. In a second variant called "Flanking Bishops" it can develop easily.
   
  The Master: Combines the moves of knight and a king. Can cover up to 20 squares, and great range of forks as it's still a leaper. Excellent for both attack and defense, this piece (valued about 7 pawns) stands in power between the Queen and the Rook; but it's actually the best piece can be promoted to, by a pawn. In the middle game his power equals even the Queen. In a second variant called "Flanking Bishops" can be rapidly developed.
