A serious, reasonable suggestion in the randomizing back rank theme for Orthodox Chess. However-- allowing for some license to re-direct the subject matter to CVP entries-- Fischer-random, Shuffle-, or Slide-shuffle as methods for determining initial set-ups, can be adapted to most (90%+) of the 2000 chess variations listed in CVP. It would not be applicable to only one. And each starting array, being able to generate its own data base of specific games, could stand as a unique Game in itself. (Similar to Gothic Chess' considered switch of two pieces warranting its patents) Taking the mentioned 2880 starting positions as near the average, or rounding to 3000, there are now 6 million distinct variants available. Insofar as sheer numbers are the usual goal here, Ralph Betza's Polypiece concept of fluctuating piece powers generates at the very least 1000 cases per chess variant. Overlaying these makes 6 billion separate Sets of Rules. Further, coordinate pieces, hardly used at all to date beyond the time-worn King-Coordinator rank-file standard, could easily contribute another 10*3 factor: 6+ trillion game-play methods-- each capable of having own actual scores. If Orthodox Chess is up to 3 or 4 million of those, then such unique sets of rules (6x10*12), as attainable methods of play (the coequality of all forms ever being sacrosanct), may someday translate into near 25 quintillion games of Chess. [Or, supported by proposed novelties, factor in comparable quantities, mostly on order of 10*3, for Pawns, King moves, Castling rules, time controls, move-turn order, immobilization and reduction, and any twenty(20) other important parameters; then the Googol is in reach: a Googol chess variants and still more games...]
