I have read that the game of chess was invented by giving each piece different powers in a 5x5 grid.
The Bishop used to be the Alfil and jumped 2 squares diagonally. The Queen used to be the weakest piece on the board, moving only one diagonal square at a time. The Rook was the same.
Mapping out each piece's powers, so far:
The Knight got the leftovers.
With computer advances, it could be expanded to be 12x12 in the future.
In an other thread I was depicted as an idiot for requiring chess to be played on a bigger board to avoid engines. Posts like this strengthen me somewhat that !'m not alone with my idea.
