Centaur(NB) and Champion(RB) are four hundred years old soon and look-alikes include: Aberg, Bird's, Capablanca's, Ladorean, Teutonic, Optimized, Paolowich, Embassy, Univers. In fact, Sam Trenholme at ''10x8 Variants'' thread kindly documents over 100 of them including his own Schoolbook. How can you have CV of one's own with Capa-pieces? Just follow two-step recipe: (1) Copy the starting array and rules of any of the above. (2) Add rule that En Passant and/or Castling shall be only to the right or only to the left. Voila. That is sufficient to distinguish yours from any run-of-the-mill fine-tuning because of the peculiar uniqueness of application, either 1/2 e.p. or 1/2 castling, neither ever before tried. A New CV. Enter it into post-it of cvpage or just keep it for use at home. As of now, it is only a theoretical construct in ChessboardMath7. In general, with unsymmetrical boards (Ramayana, Slanted Escalator, Ultra Slanted Escalator), e.p. should be permitted where the greater action is likely to be and excluded where the board is sparse. In general, since most starting positions lack full symmetry (you know, Queen faces Queen and Queen faces King crosswise), castling allowed only to the short side, i.e. Kingside, has yet unrealized potential; and some inventor ought to eliminate Queenside castle maneuvre entirely, verboten. CbM7 is for disequilibrated e.p. and disequilibrated castling; also for unsymmetrical boards. In Ramayana case in point, pieces will try to leap into the Archipelago to some extent, and appropriately Pawns should be subject to e.p. nearby. If a Pawn wants to slip by two-sliding, let him do so towards the other perimeter of the narrow board four-wide. (By the way, it is easily shown and proved there are far, far more unsymmetrical boards than symmetrical, on any hierarchy of symmetry.)
